Dear Governor and Legislative Leaders:
As directed by the Joint Legislative Audit Committee, my office conducted an audit of the California
Department of Health Care Services (DHCS) and the California Department of Public Health (CDPH).
Our assessment focused on both the administration of lead tests to children in Medi-Cal and the
activities of the Childhood Lead Poisoning Prevention Program, and the following report details
the audit’s findings and conclusions. In general, we determined that millions of children in Medi-Cal
are not receiving the lead tests they should be receiving, and CDPH is not prioritizing the prevention
of lead poisoning.
State law generally requires that children enrolled in Medi-Cal receive tests for elevated lead levels
at the ages of one and two years. When we reviewed data maintained by DHCS, we found that from
fiscal years 2009–10 through 2017–18, more than 1.4 million of the 2.9 million one- and two-year-old
children enrolled in Medi-Cal did not receive any of the required tests, and another 740,000 children
missed one of the two tests. As a result, the rate of eligible children receiving all of the tests that
they should have was less than 27 percent. Without these tests, health care providers do not know
whether these children are suffering from elevated lead levels and need treatment. Despite low lead
testing rates, DHCS has only recently begun developing an incentive program to increase testing and
a performance standard for measuring the extent to which managed care plans are providing the tests.
We also found that CDPH, which manages the State’s Childhood Lead Poisoning Prevention Program,
does not focus on proactive abatement of lead hazards to prevent future poisoning. Instead, CDPH
requires local childhood lead poisoning prevention programs (local prevention programs), to which it
delegates many of its responsibilities, to monitor abatement in the homes of children who have already
been poisoned. However, such efforts only prevent future poisoning in those specific homes. Although
CDPH claims that the local prevention programs are reducing lead exposure through education and
outreach, it could not demonstrate the effectiveness of this outreach. Finally, CDPH has failed to meet
several legislative requirements, including a mandate to update the factors that health care providers
must use to determine whether a child is at risk of lead exposure, which help them identify children
who need testing.
Respectfully submitted,

states have successfully used to increase testing rates.
Like DHCS, CDPH has not adequately met its responsibilities to
protect children from lead poisoning. Although state law requires
CDPH to identify geographic areas at high risk for childhood
lead exposure and publish an analysis of this information each
year beginning in March 2019, CDPH had not yet done so as of
October 2019. In addition, it failed to meet a statutory requirement
to post on its website a list of certain census tracts in which
children have tested positive for specified lead levels. An analysis we
performed using CDPH’s data shows that the number of children
with elevated lead levels varies significantly by geographic area.
Specifically, from fiscal years 2013–14 through 2017–18, half of
children with elevated lead levels were located in just 15 percent
of the State’s census tracts.
Although CDPH is responsible for reducing the incidence of
excessive lead exposure in children, its current efforts do not
appear to align with preventing future instances of lead poisoning
in those geographic areas in which children are at the greatest risk.
Specifically, CDPH has not proactively identified such high-risk areas
and taken steps to abate lead risks in these locations. In fact, CDPH
contracts with childhood lead poisoning prevention programs at
local agencies (local prevention programs) to increase the testing of
at-risk children, to provide follow-up services for children with lead
poisoning, and to eliminate lead in the environment. However, it
only requires these programs to monitor abatement in the homes of
children who already have lead poisoning, even though that effort
prevents future poisoning only in those specific homes. In addition,
although CDPH claims that local prevention programs are reducing
lead exposure in high-risk areas through outreach, it could not
demonstrate the effectiveness of this outreach.
CDPH has also not been proactive in managing the State’s
Childhood Lead Poisoning Prevention Program. For example, in
recent years, CDPH failed to meet several legislative mandates that
could enable it and health care providers to better identify children
who need testing for elevated lead levels. One such mandate
requires CDPH to update the factors health care providers use
to determine if children are at risk of lead exposure. In addition,
California State Auditor Report 2019-105 3
January 2020
CDPH has not taken steps to advocate for changing a state law that
currently makes it optional for laboratories to report certain contact
information with test results for children tested for elevated lead
levels. This state law does not require the use of a unique identifier
that would allow CDPH to effectively match lead tests with existing
cases of lead poisoning. The fact that this information is missing
from lead tests has contributed to CDPH’s backlog of unprocessed
test results and impeded its ability to contact families and monitor
lead poisoning cases. Finally, CDPH has allocated funding to local
prevention programs based on a funding formula that uses outdated
information on the number of children with lead poisoning in each
jurisdiction. This funding formula has led to significant differences
in the services that local prevention programs have been able to
provide to children with lead poisoning.
Summary of Recommendations:
Legislature
To support CDPH’s efforts to efficiently contact families and
monitor lead test results, the Legislature should amend state law
to require laboratories to report contact information and unique
identifiers with children’s lead test results.
DHCS
Because of the severe and potentially permanent damage that lead
exposure can cause in children, DHCS should do the following:
• Prioritize its effort to adopt a performance standard for lead tests
and ensure that this standard is specifically designed to monitor
its success in meeting the State’s requirements for the lead testing
of one- and two-year-old children.
• Incorporate into its contracts with managed care plans a
requirement that the plans identify each month all children
without records of required lead tests and remind the responsible
health care providers of the need to test those children.
CDPH
To identify the highest priority geographical areas for using
resources to alleviate lead exposure among children, CDPH should
immediately complete and publicize an analysis of high-risk areas
throughout the State.
4 California State Auditor Report 2019-105
January 2020
To ensure that local prevention programs’ outreach results
in a reduced number of children with lead poisoning, CDPH
either should require local prevention programs to demonstrate
the effectiveness of their outreach or should analyze the
cost-effectiveness of approaches such as proactive abatement and
require the local prevention programs to replace or augment their
outreach to the extent that resources allow.
To better ensure that children with lead poisoning are identified and
treated, CDPH should prioritize meeting legislative requirements,
including updating the factors health care providers use to
determine whether children are at risk of lead exposure.
To ensure a more equitable distribution of resources for treating
children with lead poisoning, CDPH should update its allocation
formula to take into account the most recent data for the number of
children with lead poisoning in each jurisdiction.
Agency Comments
DHCS agrees with our recommendations, but its approach for
implementing certain recommendations does not fully address the
related findings. CDPH agreed or partially agreed with most of our
recommendations. However, its proposed implementation plan does
not sufficiently address several concerns described in our report.

Introduction
Background
Lead is a naturally occurring toxic metal with many uses. It is
highly damaging when absorbed into the human body, particularly
for children. The amount of lead in the environment rose
dramatically during the 20th century, reflecting the increased
worldwide use of leaded gasoline. Lead was also widely used in
house paint and plumbing pipes and fixtures, and it continues to be
used in batteries and electronics. Although the federal government
has now banned some uses of lead, its nonbiodegradable nature and
continuous use means that it has accumulated in the environment,
causing lead poisoning in both children and adults. Today lead can
be found in the air and soil. It is also present in the drinking water
of housing and other structures that contain lead pipes, such as
some schools.
Children younger than six years of age are especially vulnerable to
lead poisoning and its harmful effects. Because of their increasing
mobility and normal developmental behavior, the blood lead
concentrations of children in lead-contaminated environments
typically increase rapidly when those children are between the ages
of six months and 12 months, and they peak when the children
are between 18 months and 36 months of age. Young children
also absorb lead more efficiently than adults and are less likely to
eliminate it through their waste once it has entered their bodies.
Further, children are more sensitive than adults to the negative
health effects of lead exposure, some of which may be irreversible.
The primary way to determine whether a child has been exposed to
lead is to perform a blood test. Lead exposure is generally measured
by the level of lead in a person’s blood, expressed in micrograms
per deciliter (micrograms). For the purpose of this report, we define
childhood lead poisoning as a child’s blood lead levels reaching or
exceeding a concentration of 10 micrograms of lead per deciliter
of blood, which is the point at which health care providers in
California are required to take action to reduce the child’s lead
level.2 Although extreme lead poisoning can lead to seizures
and death, studies have indicated that even lead levels below
10 micrograms per deciliter can affect normal growth patterns.
Studies have also shown that low levels of lead exposure at an early
age can lead to reduced IQ, as Figure 1 shows. This exposure can
affect children’s ability to pay attention and to succeed in school,
and it can cause decreased productivity when those children
2 Because California rounds lead test results to the nearest whole number, this definition includes
lead levels of 9.5 micrograms and greater.

become adults. According to research cited by the American
Academy of Pediatrics, one in five cases of attention-deficit/
hyperactivity disorder among U.S. children has been attributed to
lead exposure.

Many California Children Face the Health Risks of Lead Exposure
Thousands of California children have experienced elevated lead
levels.3 The California Department of Public Health (CDPH)—
which receives lead test results from laboratories and health care
providers—provided reports showing that the percentage of children
with elevated lead levels has dropped considerably since 2010,
and the number of children tested also decreased significantly.
Nevertheless, as Table 1 shows, nearly 10,000 children in California
in 2017 had elevated lead levels that met or exceeded CDPH’s criteria
to provide, at a minimum, education and outreach related to lead
poisoning. Of these children, 86 percent were younger than six years
old. Further, the number of children with lead at these elevated levels
increased by more than 1,000 from 2015 to 2017, even as the number
of children tested declined by nearly 15,000.

Residential sources of lead exposure pose a health hazard to
children in California. Lead-based paint and lead-contaminated
dust in older buildings, along with lead-contaminated soil, are the
most common sources of exposure for children with elevated lead
levels. Lead-contaminated dust in homes is frequently a byproduct
of deteriorating lead-based paint on surfaces, especially those
that rub together, such as sliding windows. Similarly, urban soil
has often been contaminated by the past use of lead-based paint
and leaded gasoline, among other sources. In some communities,
airborne emissions from the ongoing operation of battery recyclers,
incinerators, and piston engine aircraft also may contaminate soil.
Other sources of lead poisoning include certain imported foods
and spices, traditional remedies, cosmetics, ceramic dishware,

jewelry, toys, bullets, and fishing weights, as Figure 2 shows. Finally,
take-home lead exposure—when children are exposed to lead that
adults bring home from their jobs—is another common source of
childhood lead poisoning. A CDPH analysis of the sources of lead
exposure for a sample of 188 children in 31 counties during fiscal
year 2015–16 indicated that the children were exposed to lead from
a variety of sources, including 30 from take-home sources and
37 from items such as cosmetics or remedies.

The State and the federal government have been working for
decades to prevent childhood lead poisoning. Congress approved
the creation of the U.S. Environmental Protection Agency (EPA)
in 1970 to address a variety of environmental concerns. In 1971
Congress passed the Lead-Based Paint Poisoning Prevention Act
to determine the nature and extent of the problem of lead-based
paint poisoning and how lead paint hazards could most effectively
be removed from housing where children might be exposed.
In 1973 the EPA implemented regulations that began reducing the
lead content in leaded gasoline in 1975. The federal government
banned the manufacture of lead paint for use in residential
properties in 1978 and banned lead pipes in 1986, and in 1990
it prohibited the sale of leaded automobile gasoline after 1995.
Additionally, Figure 3 shows that the U.S. Centers for Disease
California State Auditor Report 2019-105 9
January 2020
Control and Prevention (CDC) has gradually lowered the definition
of an elevated blood lead level from 60 micrograms in 1960 to
5 micrograms in 2012, when it concluded that no level of lead
exposure is safe.

Although federal law no longer allows lead to be used in residential
paint, gasoline, or plumbing, lead contamination from these and a
variety of other sources continue to contribute to childhood lead
exposure. Because of lead’s durability, lead paint and plumbing lines
10 California State Auditor Report 2019-105
January 2020
frequently remain for many decades after installation. Also, according
to the federal Agency for Toxic Substances and Disease Registry,
lead that falls onto soil sticks to soil particles and lingers in the upper
layer, which is why past uses of lead in gasoline and paint continue to
contribute to the lead found in soil today. Finally, lead is still used for
other purposes, as Figure 2 shows, and is still used in some products
in other countries. Children in California can be exposed to these
products through foreign travel or through the importation of the
products.
The California State Legislature declared that childhood lead exposure
was the most significant childhood environmental health problem in
the State when it established the State’s Childhood Lead Poisoning
Prevention Program (lead prevention program) in 1986 to, among other
things, reduce the incidence of excessive childhood lead exposures.
In 1991 the Legislature expanded the lead prevention program to
include case management for children with lead poisoning and lead
testing for at-risk children. At the same time, it created a fee that
manufacturers of certain products that contribute or have contributed
to environmental lead contamination must pay to help support the lead
prevention program.
With Limited Exceptions, State and Federal Requirements Mandate That
Children Enrolled in Medi‑Cal Receive Lead Tests
In accordance with state law, California employs a targeted approach
for testing children the State believes to be at the greatest risk of lead
poisoning. This includes testing children enrolled in the California
Medical Assistance Program (Medi-Cal) or other publicly funded
programs for low-income children. With limited exceptions, state
and federal requirements mandate that all children enrolled in
Medi-Cal receive lead screening tests at 12 months of age and again
at 24 months of age. DHCS, which oversees the Medi-Cal program,
adopted a schedule of care for children in Medi-Cal that includes
these required tests. However, according to federal Medicaid data for
2017, California ranked 31st among states in the nation for providing
lead tests to children at these ages.
State regulations also generally require that children in Medi-Cal
from two to six years of age who were not tested at age two be tested
whenever their providers become aware of the missed test. Further,
state regulations require that health care providers inform parents or
guardians of all children—whether or not they are in Medi-Cal—about
lead poisoning at each periodic health assessment from the time they
begin to crawl until six years of age. DHCS’ recommended schedule
of care for children in Medi-Cal also includes periodic lead risk
assessments from age six months to six years. Moreover, beginning
January 1, 2018, state law has required CDPH to develop regulations
California State Auditor Report 2019-105 11
January 2020
identifying which environmental risk factors health providers must
consider when determining whether children are at risk of lead
poisoning. Although state law permits parents or guardians to refuse
lead tests for their children, CDPH and DHCS both stated that they
do not track these refusals.
CDPH Contracts With County and City Agencies to Reduce and Prevent
Lead Poisoning in Children
Although DHCS oversees the provision of lead tests to children in
Medi-Cal, CDPH is the state agency responsible for overseeing the
statewide lead prevention program and implementing it in a way
that will reduce the incidence of excessive childhood lead exposures.
In addition, when lead tests identify that a child has lead poisoning,
state law requires CDPH to ensure the delivery of appropriate case
management services for that child. These case management services
include nutritional assessments and home visits by public health
nurses, as Table 2 describes.
Table 2
Children With Lead Poisoning Are Provided Access to a Variety of Services
EXAMPLES OF
DESCRIPTION
SERVICES
Nutritional An assessment of the child’s nutritional status by a public health nurse or the child's health care provider. This
Assessment assessment includes evaluating eating habits, dietary intake, and possible food sources of lead poisoning.
Nutritional guidance can be instrumental in decreasing the child’s susceptibility to lead absorption and retention.
Home Visit A visit by a public health nurse to the child's home to perform a nutritional assessment, assess the needs and
capabilities of the family, explain the case management services the State or local prevention program will
provide, educate the family about lead poisoning, discuss the importance of follow‑up tests, and help the
family understand practical approaches to reducing lead exposure in the home. The public health nurse also
searches for possible sources of lead poisoning, such as imported food and spices and lead‑soldered cans. CDPH
recommends that the home visit and environmental investigation be conducted together, if possible.
Environmental An environmental professional holding one of several qualifications, such as certification as a CDPH inspector/
Investigation assessor, performs an assessment at the address at which the child resides. The assessment consists of a number
of elements, including testing potential sources of lead poisoning, such as paint, dust, soil, and water. If lead
hazards are identified, the environmental professional notifies the property owner of the requirement to abate
the hazards and must follow up with the property owner until the lead hazards are abated. After the lead hazard
control work is performed, the environmental professional performs a clearance inspection to ensure that the
work was performed and no lead contaminated dust remains. As resources permit, environmental inspections
may also be performed at an additional property where the child spends a significant amount of time. CDPH
recommends that the home visit and environmental investigation be conducted together if possible.

As Figure 4 illustrates, CDPH currently contracts with 50 local
prevention programs. These programs are located in 46 counties,
three cities, and the city and county of San Francisco. The
programs—which local public health departments operate—are
intended to accomplish a number of goals, such as increasing
the testing of at-risk children, providing case management for
children with lead poisoning, and eliminating certain sources
of lead exposure. In some contracted counties, CDPH performs
the environmental investigations, during which an inspector
examines a child’s home for sources of lead exposure. In areas
where the local public health departments choose not to contract
with CDPH, CDPH provides the required case management
services directly. However, two noncontracted counties currently
perform their own environmental investigations, while CDPH
provides the public health nursing services in those counties.
Figure 5 shows the relationships between CDPH, DHCS, and
local prevention programs.
The Lead Prevention Program Relies on a Dedicated Funding Source
but Is Currently Operating at a Deficit
The lead prevention program is funded through fees that the State
collects from manufacturers or other parties that have contributed
or currently contribute to environmental lead contamination. State
law has required these manufacturers and other parties to pay this
fee annually since 1993. The Legislature originally capped the total
amount that the State could collect from this fee at $16 million
per year, adjusted for inflation. However, CDPH used its authority
through state law to issue regulations effective 2001 to increase this
amount to $22 million, after we recommended that it do so in our
May 2001 report titled Department of Health Services: Additional
Improvements Are Needed to Ensure Children Are Adequately
Protected From Lead Poisoning, Report 2000-013. In that report, we
discussed projected funding shortfalls that threatened the level of
services CDPH’s lead prevention program was providing.
CDPH retains any unspent funds it collects in the Childhood
Lead Poisoning Prevention Fund (lead prevention fund), which the
Legislature established. As a result of various legal settlements,
the reserve balance in this fund increased from $2 million in
fiscal year 2007–08 to $63 million in fiscal year 2011–12. However,
after several years when it mostly operated at a surplus, the lead
prevention program operated at a deficit in fiscal year 2014–15.
Further, when CDPH broadened its definition of lead poisoning
to include lower lead levels in fiscal year 2016–17, it increased its
program costs and used its reserves to make up for the shortfall.
By fiscal year 2018–19, the program’s budgeted operating deficit had
increased to more than $13 million per year.

As Figure 6 shows, at its current spending rate and without a fee
increase, we project that CDPH will deplete its fund balance during
fiscal year 2021–22. This projection takes into account that in 2019
CDPH received approval to spend an additional $9 million from the
lead prevention fund for state operations—$8 million of which is for
an information technology project. These expenditures will increase
the lead prevention program’s deficit to more than $23 million
in fiscal year 2019–20, or more than twice as much as it will receive
from the lead prevention fee, thereby accelerating the depletion
California State Auditor Report 2019-105 15

of its reserves. CDPH is considering increasing the total fees by
$21.5 million annually, roughly double the amount it currently
collects. Because state law requires that the lead prevention
program be fully supported by the revenue collected from the lead
prevention fee, CDPH stated that unless a fee increase is approved,
it will not be able to pay for its expected level of operations.
According to CDPH, it has not identified the specific services it
would have to reduce.

January 2020
Chapter 1
DHCS’ FAILURE TO ENSURE TIMELY LEAD TESTING OF
CHILDREN IN MEDI‑CAL HAS PLACED THEM AT RISK FOR
PERMANENT HEALTH PROBLEMS
Chapter Summary
Millions of children in Medi-Cal are not receiving the tests they
need to determine whether they have lead poisoning and require
treatment. DHCS’ data show that from fiscal years 2009–10
through 2017–18, 1.4 million of the State’s 2.9 million one- and
two-year-old children enrolled in Medi-Cal were not tested,
and another 740,000 children missed one of the two tests they
should have received. Some of these children reside in areas of
the State with high occurrences of elevated lead levels, making
the missed tests even more alarming. Nonetheless, DHCS has not
effectively overseen the managed care plans with which it contracts
to provide lead tests to children in Medi-Cal. Specifically, DHCS
does not require the plans to follow up with health care providers
that do not report administering lead tests, and its method of
determining whether managed care plans ensure that providers
administer these tests is not effective. Although DHCS plans to
implement a performance standard for lead testing and a financial
incentive program to encourage lead testing, it has not yet done so.
In the meantime, DHCS could direct managed care plans to inform
providers immediately about children who have missed tests and
the need to test them and report those tests.
DHCS Has Failed to Ensure That Health Care Providers Administer
Required Lead Tests for Millions of Children
DHCS has not ensured that all children enrolled in Medi-Cal
receive the lead tests to which they are entitled. State regulations,
with few exceptions, require health care providers to administer
tests for elevated lead levels for one- and two-year-old children who
are enrolled in Medi-Cal. However, DHCS’ data show that from
fiscal years 2009–10 through 2017–18, health care providers failed
to administer all of the required tests for nearly three-quarters of
these children, as Figure 7 demonstrates. According to DHCS’ data,
1.4 million of the 2.9 million one- and two-year-old children in
Medi-Cal were not tested, and an additional 740,000 children missed
one of the two tests they should have received during those years.
These data—which, as we discuss below, may contain inaccuracies—
suggest that the rate of eligible children receiving all of the tests that
they should have was less than 27 percent.

DHCS has also failed to ensure that children are tested by age six.
State regulations generally require that children in Medi-Cal who
are from two to six years old and who were not tested at age two
be tested once their health care providers become aware of the
missed tests. However, DHCS has not ensured that these children
are tested, despite having the necessary information to make
this determination. Moreover, it does not require managed care
plans to notify health care providers that these children have not
been tested. When we evaluated DHCS’ data related to children
in Medi-Cal who turned six years old during fiscal years 2015–16
through 2017–18, we found that of the 466,000 children who
did not receive lead tests at age two, only 152,000, or 33 percent,
received lead tests before age six, as required. Until these children
are tested, their health care providers cannot know if they have
elevated lead levels and need treatment.
Further, some of the children who did not receive the required lead
tests reside in areas of the State with high occurrences of elevated
lead levels. When we reviewed CDPH’s data on the location of
children with elevated lead levels, we found that some geographic
California State Auditor Report 2019-105 19
January 2020
areas had a higher number of such children. For example, nine of
the census tracts with the largest number of children less than age
six that had elevated lead levels during fiscal years 2013–14 through
2017–18 are in Sacramento County, including the census tract
with the largest number of such children in the State. Appendix B
shows the 50 census tracts throughout California where we noted
the highest numbers of children less than age six with elevated
lead levels.
Figure 8 shows the locations of children in Medi-Cal who,
according to DHCS’ data, missed tests they should have received.
When we compared DHCS’ data on children in Medi-Cal at ages
one and two years who had not received tests with CDPH’s data
on the location of children less than age six with elevated lead
levels, we found that some of the geographic areas with the largest
populations of children with elevated lead levels also had a large
number of children enrolled in Medi-Cal who missed required
tests. For example, in the Sacramento census tract described
above, DHCS’ data show that children in Medi-Cal at ages one
and two years received just 392, or 35 percent, of the 1,135 lead tests
they should have received, despite the fact that these children may
be at a high risk for lead exposure. DHCS’ data show that in the DHCS’ data show that in the
50 census tracts with the highest number of children less than age 50 census tracts with the highest

had administered and that the testing rates were actually higher
than its data show. According to DHCS, its data do not reflect a
lead test if a health care provider administers it but only records an
office visit. However, laboratories are required to report to CDPH
all lead test results for blood drawn in California. Nonetheless,
even after combining the lead test results that health care providers
reported to CDPH with DHCS’ data, the resultant data still show
that a majority of children did not receive all of the required tests.
For example, in 2018 the two agencies reported that by combining
their data for those children continuously enrolled in Medi-Cal for
12 months during federal fiscal year 2015 they were able to identify
additional blood lead tests that had been provided, which changed
the percentage of children with an identified test from 40 percent to
49 percent for children aged 12 to 23 months and from 33 percent
to 41 percent for children aged 24 to 35 months.4

California State Auditor Report 2019-105 21
January 2020
Our analysis of DHCS’ and CDPH’s data also demonstrates that
even when CDPH’s data is included, more than half of children in
Medi-Cal did not receive the tests necessary to determine whether
they need treatment. Specifically, we found that combining lead test
data from CDPH with DHCS’ data identified another 8 percent of
children who were eligible at one and two years old and received
both tests during fiscal years 2009–10 through 2017–18. This analysis
confirms that DHCS’ data alone do not include all of the lead tests
children receive, leading us to question why DHCS has not yet
implemented processes to ensure the accuracy of the information it
collects. More importantly, this analysis also confirms that more than
half of children did not receive the required tests. The two agencies
also developed an estimate of the number of children in Medi-Cal
who turned three years old in federal fiscal year 2016, who were
enrolled in Medi-Cal all three years, and who received a single lead
test by age three years. However, even under these more lenient
criteria, the analysis showed that more than a quarter of the children
in Medi-Cal had not received a single lead test by the age of three.
DHCS Has Not Effectively Overseen the Managed Care Plans’ Provision
of Lead Tests
DHCS has not demonstrated effective oversight of the managed care
plans’ provision of lead tests. Although DHCS requires the managed DHCS requires the managed care
care plans to report to it the lead tests they provide, DHCS does not plans to report to it the lead tests

requirements; however, it does not verify that the plans follow up
with health care providers that do not report administering lead tests,
nor do its contracts with the plans specifically require this sort of
follow-up. The monitoring chief stated that DHCS delegates oversight
of this issue to the managed care plans but does not know how the
plans ensure that health care providers are administering lead tests,
other than through the reviews of provider records that it requires
managed care plans to conduct.
The monitoring chief described the facility site review (FSR) process
as DHCS’ means of oversight for ensuring children in Medi-Cal
receive blood lead tests. The FSR process involves the managed care
plan reviewing the medical records of a small sample of patients
at each primary health care provider site once every three years
to verify whether those patients are receiving sufficient care, such
as lead tests. However, this process does not adequately identify
health care providers who are failing to administer childhood lead
tests because it involves a sample of only 10 patients, which is not
limited to young children. A DHCS medical program consultant
22 California State Auditor Report 2019-105
January 2020
acknowledged that the FSR process is not a comprehensive approach
for determining whether children have received lead tests in part
because it looks at so few records. In addition, even when managed
care plans conduct an FSR and identify health care providers that
have failed to administer required lead tests, the plans do not
implement corrective actions unless those providers have also failed
to administer a variety of other pediatric services.
Moreover, DHCS has not fully implemented a way to ensure that
providers report the tests they administer. The underreporting we
previously describe suggests that some providers lack motivation
for administering and reporting tests. In 2018 the director of DHCS
at that time stated that health care providers did not have sufficient
incentive to report all of the services they administered. To create
an incentive for providers not only to administer lead tests but also
to report the tests they do administer, DHCS received approval in
June 2019 to provide payments to providers for each lead test they
report administering on or before a child’s second birthday. However,
we are concerned with how long it will take to begin making
these payments because as of September 2019, DHCS had not yet
determined when it would begin making these payments.
It is unclear how long it will be until DHCS can evaluate the success
of this program. DHCS plans to measure the program’s success by
evaluating lead testing rates over time, but it does not currently use
a performance measure for managed care plans’ reporting of lead
testing, despite the effectiveness of such standards. Our March 2019
audit report titled Department of Health Care Services: Millions of
Children in Medi‑Cal Are Not Receiving Preventive Health Services,
Report 2018-111, concluded that children receive services more often
when DHCS imposes performance measures on managed care
plans related to those services. In that report, we recommended that
DHCS establish performance measures for children’s preventive
services. Implementing a similar performance measure specific to
lead testing may increase testing rates. According to its monitoring
chief, DHCS is in the process of establishing a standard to assess the
DHCS is several years away from plans’ performance in providing lead tests and intends to work with

While it continues to develop its method of monitoring and
enforcing lead testing requirements for managed care plans, DHCS
could require them to inform health care providers of missed tests.

Services (CMS) data show that California’s 36 percent lead testing

lead tests.
Several states with Medicaid lead testing rates in the top 20 percent
of the nation, including Michigan and Wisconsin, performed
targeted outreach by identifying children who were not tested
and following up with health care providers who were not in
compliance with testing requirements. For example, beginning
in 2006, Wisconsin’s Medicaid staff collaborated with its state
lead prevention program staff to send reports to Medicaid health
care providers identifying their testing rates and the children
in their care who had not received the appropriate blood lead
tests. Wisconsin’s 2014 Department of Health Services’ report
on childhood lead poisoning indicates that testing subsequently
increased 29 percent, from almost 82,000 children tested in 2006 to
more than 106,000 in 2010. The program ended after 2011 because
of a loss of federal grant funding, and the number of children tested
then decreased each subsequent year—dropping to about 84,000
by 2016. By requiring managed care plans to identify the health care
providers for the children in Medi-Cal who have not received all of
their required lead tests and informing those providers of the tests
that they need to administer, DHCS would reinforce testing and
reporting requirements.
DHCS could also use the data that we summarize in Figure 8 to
identify children who have not received the required tests and
contact their families. Our March 2019 audit report concluded that
DHCS was not meeting a requirement in federal law to perform
annual outreach to the families of children who have not received
preventive services, such as blood lead tests, to inform them of the
benefits of preventive health care and explain how to obtain these
types of services. Although DHCS stated at the time that it relies on
the managed care plans to follow up with families of children who
have not used preventive services, we found that the plans had not
adequately communicated with these families. In that report we
recommended that DHCS ensure that families of children who do
not use preventive services are contacted annually. DHCS indicated
in its six-month response to that report that it is developing a
process to follow up with the families of children who have not
received preventive services over the course of a year.
5 CMS’s data represents a one‑year snapshot of the percentage of children ages 1 and 2 years
continuously enrolled in Medicaid for 90 days or more who had at least one lead test. CMS’s
numbers differ from ours because we looked at multiple years of data to determine whether
children received all, one, or none of the tests that California requires. We reference CMS’s data
here so that we can compare California’s performance with that of other states.
California State Auditor Report 2019-105 25
January 2020
Similarly, DHCS does not reach out to the families of children
who have not received lead tests. DHCS’ monitoring chief was not
able to provide a reason for why it does not do so. However, as we
describe above, federal law requires DHCS to inform children or
their families about the services that they are eligible to receive
and also requires DHCS to provide lead testing as part of those
services. Most importantly, because lead testing is the primary way
to determine whether a child needs treatment for lead poisoning,
DHCS’ failure to contact their families to follow up on missed tests
leaves children at risk.
Recommendations
DHCS
Because of the severe and potentially permanent damage that
lead poisoning can cause in children, DHCS should ensure
that all children in Medi-Cal receive lead tests by finalizing, by
December 2020, its performance standard for lead testing of
one- and two-year-olds. DHCS should use its existing data to assess
the progress of managed care plans in meeting that performance
standard and impose sanctions or provide incentive payments as
appropriate to improve performance.
To ensure that families know about the lead testing services
that their children are entitled to receive, DHCS should send a
reminder to get a lead test for children who missed required tests.
It should send this reminder in the required annual notification
it is developing to send to families of children who have not used
preventive services over the course of a year.
To increase California’s lead testing rates and improve lead test
reporting, DHCS should, by no later than June 2020, incorporate
into its contracts with managed care plans a requirement for the
plans to identify each month all children with no record of receiving
a required test and remind the responsible health care providers
of the requirement to test the children. DHCS should also develop
and implement a procedure to hold plans accountable for meeting
this requirement.

Chapter 2
CDPH HAS NOT PRIORITIZED ITS MISSION TO PREVENT
LEAD EXPOSURE
Chapter Summary
CDPH has not sufficiently identified areas of the State at high risk
for childhood lead exposure, nor has it met its obligation to reduce
the lead risks in those areas. CDPH’s data show that the number of
children with elevated lead levels varies significantly by geographic
area, but CDPH does not have an effective method of proactively
reducing lead risks in the areas where elevated lead levels are most
prevalent. Instead of addressing lead hazards before children are
exposed to them, CDPH’s approach is to monitor lead abatement
activities in the homes of children who already have lead poisoning.
Further, CDPH largely delegates responsibility for addressing lead
risks to local prevention programs—the county and city agencies
we describe in the Introduction—but it does not sufficiently assess
their performance. According to CDPH, it does not have the funds
to perform proactive abatement of all regions of the State where
children are at risk for lead exposure, yet it has not sought funding
on behalf of the local prevention programs to accomplish abatement
activities. Further, it could provide better information to the public
about lead risks, particularly in properties being sold or rented.
CDPH Has Not Identified Areas Where Children Are at High Risk for
Lead Exposure
Although state law requires CDPH to identify areas of the State
where childhood lead exposure is especially significant, it had
failed to complete this analysis as of October 2019. Specifically,
since 1986, state law has required CDPH to identify geographic
areas at high risk for lead exposure. However, CDPH last reported
a list of high-risk areas using data from 2015. A more recent
state law requires that commencing March 1, 2019, and annually
thereafter, CDPH must publicly post an updated analysis of
the high-risk geographic areas and other information related to the
lead prevention program on its website. However, as we discuss
in Chapter 3, CDPH has not met this deadline. Because it has not
completed this analysis, CDPH lacks information on the locations
where the risk of lead exposure is most significant.
In contrast to CDPH’s approach, Washington and Colorado have
both created interactive maps that they publicly post detailing lead
exposure risk by geographic area. They also use these maps to target
their outreach and intervention efforts. If CDPH knew where the
28 California State Auditor Report 2019-105
January 2020
highest risk of lead exposure was, it could prioritize the resources it
has to reduce the incidence of excessive lead exposure in those areas
and better prevent lead exposure—the requirement established in
state law and a goal described in the mission of CDPH’s childhood
lead poisoning prevention branch.
In addition to an analysis of high-risk geographic areas, state law also
required CDPH, to the greatest extent possible, to post on its website
by March 1, 2019, a list of the census tracts in which children tested
positive for blood lead levels at rates that are higher than the national
average and that are in excess of the level CDC considers elevated.6
CDPH informed us that in March 2019, it completed a draft version of
a report addressing this requirement. However, despite the assertion
of CDPH’s lead prevention program branch chief (branch chief) that
CDPH intended to approve the draft report for public release as soon
as possible, it had still not done so as of October 2019. The branch
chief subsequently indicated that CDPH would publish the report by
December 2019 and provided several explanations for the report’s
delay, including a lack of staff capacity, the vacancy of a branch chief,
and the fact that the draft is currently under review by CDPH’s Office
of Legislative and Governmental Affairs.
Our analysis of data from CDPH’s case management system shows
that elevated lead levels vary significantly by geographic area. As
Figure 10 shows, the data indicate that from fiscal years 2013–14
through 2017–18, the majority of children younger than six years old
with tests showing elevated lead levels were concentrated in certain

Nonetheless, CDPH’s approach is focused on eliminating sources
of lead only for children who already have lead poisoning. Although
this approach may prevent future cases of lead poisoning in
those locations, it does not focus on prevention in the many other
locations throughout the State where lead poses a risk. In fact,
CDC’s advisory committee on childhood lead poisoning prevention
concluded in 2012 that rather than just concentrating on activities to
lower a child’s blood lead level, there is a need to reduce exposure
to known sources, such as soil, dust, paint, and water, before they
contribute to the child’s exposure. However, if CDPH does not know

January 2020
where these hazards are most prevalent and where children with
elevated lead levels are concentrated, it is unclear how it will
proactively mitigate lead exposure to protect California’s children
from future lead poisoning.
CDPH Does Not Proactively Reduce Lead Exposure
CDPH’s approach to reducing lead in the environment is to take
action after it determines a child has lead poisoning. In 1986
the Childhood Lead Poisoning Prevention Act established the
requirement for CDPH to create a program of environmental
abatement and follow-up to reduce the incidence of excessive lead
exposure. State law defines lead abatement as any set of measures
other than containment or cleaning that is designed to permanently
eliminate lead hazards or lead-based paint in public and residential
buildings. CDPH’s lead hazard reduction chief stated that CDPH’s
approach to abating lead in high-risk areas is to monitor abatement
activities in the homes of children who have already been lead
poisoned. However, this approach only prevents future poisoning
in these same homes rather than addressing lead hazards before
children are poisoned.
CDPH primarily delegates the responsibilities for addressing
environmental lead risks to local prevention programs. However,
CDPH’s contracts require abatement of lead hazards only for
children who have lead poisoning.7 CDPH’s lead hazard reduction
chief informed us that CDPH does not require local prevention
programs to perform proactive abatement but stated that their

abating lead in the environment. However, this approach relies on other individuals, such as parents
and guardians, taking action based on the outreach and education.
The extent to which individuals take such action is unknown because
neither CDPH nor the local prevention programs we reviewed
measure the effectiveness of their outreach activities in reducing the
number of children with lead poisoning. Because the Legislature has
given CDPH the responsibility to reduce the incidence of excessive
childhood lead exposure, it should take steps to ensure that the local
prevention programs’ activities are directly resulting in a reduction in
the number of children with lead poisoning.
7 CDPH’s contracts give local prevention programs the option to apply for additional lead
prevention program funding to develop and implement activities to prevent lead‑exposed
children and at‑risk children from exposure to lead hazards. These optional activities include
investigating locations where children are being exposed or have been exposed in the
past, responding as necessary with appropriate enforcement actions, investigating tips and
complaints about lead hazards, and documenting those high‑risk areas.
California State Auditor Report 2019-105 31
January 2020
In addition, CDPH does not sufficiently assess the performance
of local prevention programs. The branch chief stated that CDPH
performs a comprehensive site review of each local prevention
program, which involves its evaluating the program’s processes
for carrying out contract requirements. CDPH’s policy requires it
to conduct one site review of each local prevention program per
contract cycle. However, as of August 2019, CDPH had conducted
site visits of less than one-third of the 50 programs, despite having
already begun the third year of its three-year contract cycle. Further,
it had not conducted site visits at many of the local prevention
programs for nearly five years.
Moreover, CDPH requires the local prevention programs to submit
progress reports twice a year with updates on activities such as
their outreach efforts, environmental investigations, and home
visits to children with lead poisoning. However, CDPH’s review of CDPH’s review of lead prevention
these reports does not appear to sufficiently address performance programs’ progress reports
because its feedback generally summarizes the information that does not appear to sufficiently

activities in the first half of 2017, CDPH provided nine responses to
Los Angeles evaluating its accomplishment of its contract goals. In
six of those responses, CDPH merely summarized the information
reported and thanked Los Angeles for its efforts. In two other
responses, CDPH suggested that Los Angeles should repeat its
description of activities performed for other goals but did not offer
any insight on shortcomings. Without a more robust assessment
of the performance of local prevention programs, CDPH cannot
determine whether its method of delegating its responsibility
to address environmental lead risks is effectively preventing
lead poisoning.
CDPH Is Missing Opportunities to Facilitate Lead Abatement
Throughout the State
Although CDPH asserted that it does not have the funds to perform
proactive abatement of all regions of the State at risk for lead
exposure, it could nevertheless better ensure that it uses existing
funding effectively and apply for additional funding to perform
abatement activities in the highest risk areas. For instance, a variety
of federal grants and funding resources are available that can be
used to offset the cost of abatement and other intervention efforts.
CDC and the U.S. Department of Housing and Urban Development
have awarded grants to perform abatement and prevention
activities, and the Centers for Medicare & Medicaid Services (CMS)
offers funding that some states use for lead abatement.
32 California State Auditor Report 2019-105
January 2020
When we asked CDPH’s branch chief why CDPH has not applied for
these funds, she stated that the amount of lead exposure prevented
might not be worth the effort to manage such grants. Specifically,
she explained that such grants would require a memorandum of
understanding with DHCS, the State’s lead agency for interacting
with CMS. In addition, she stated that it would take time for CDPH
to create a team dedicated to lead hazard abatement and learn how to
contract with private abatement companies. She further asserted
that CDPH would be competing with local jurisdictions and that
such funding would pay for abatement for only a tiny fraction of
the State’s housing with lead risks. However, we do not find these
reasons compelling. As we describe previously, more than half of
the children with elevated lead levels are concentrated in 15 percent
of the State’s census tracts. Moreover, as the agency overseeing lead
poisoning prevention statewide, CDPH could efficiently facilitate
the distribution of such funding by directly applying for it and
passing it on to local programs, rather than having them expend
resources competing against each other.
Unlike California, some states use proactive methods to facilitate
lead abatement in the environment. For example, a number of
states—including Massachusetts and Maryland—maintain publicly

already require CDPH to collect lead inspection and abatement
information. In fact, according to the lead hazard reduction chief, it
receives such information on tens of thousands of properties every
year, and it maintains this information in a database. Nonetheless,
CDPH does not currently make this information available to the
public, and it does not have plans to do so.
When we asked CDPH’s branch chief about the value of such
registries, she agreed that they might encourage property owners
to abate lead on their properties. However, she suggested that
it is more useful to presume that a house built before 1978 has
lead-based paint, and she explained that the public can obtain
the age of a home from the local tax assessor’s office or realtor
websites. In addition, she noted that the data in the registry might
be misleading because some level of lead always remains after
abatement and because the data may not be current. However, the
points she raises do not appear to outweigh the value to the public
of such information. In addition, CDPH’s lead hazard reduction
chief raised concerns that its database may contain personally
identifying or medical information in cases where the inspection or
abatement resulted from its case management efforts. If CDPH uses
California State Auditor Report 2019-105 33
January 2020
the information it already collects to create a registry, it will need to
take steps to ensure that it does not make information available
to the public that could be used to identify individuals in its case
management system.
Federal law requires landlords and sellers of properties to disclose
lead hazards for most residential properties built before 1978 unless
they have been inspected and found to be free of lead-based paint.
However, according to California’s real estate disclosure guidelines
we reviewed, this information is provided with the actual leases
and contracts. As a result, potential renters and buyers may not
have this information readily available when they are comparing
their options. By providing this information to the public, CDPH
would allow individuals to make more informed decisions about
the potential risks of properties and to more accurately assess the
possibility of future costs for abatement.
Recommendations
Legislature
To provide sufficient information to homebuyers and renters, the
Legislature should require CDPH, by December 2021, to provide
an online lead information registry that allows the public to
determine the lead inspection and abatement status for properties.
To accomplish this task, CDPH should use the information it
already maintains only to the extent that it can ensure that it does
not make personally identifying information, including medical
information, public.
CDPH
To identify the highest priority areas for using resources to alleviate
lead exposure among children, CDPH should immediately complete
and publicize an analysis of high-risk areas throughout the State.
To ensure that local prevention programs’ outreach results in a
reduced number of children with lead poisoning, CDPH should, by
December 2020, require local prevention programs to demonstrate
the effectiveness of their outreach in meeting this goal. If the local
prevention programs are unable to demonstrate the effectiveness
of their outreach in reducing the number of children with lead
poisoning, CDPH should analyze the cost-effectiveness of other
approaches, including proactive abatement, and require the local
prevention programs to replace or augment outreach to the extent
resources allow.
34 California State Auditor Report 2019-105
January 2020
To offset the cost of mitigating lead exposure in the highest-risk
areas of the State, CDPH should seek out and apply for additional
lead prevention funding as funding opportunities become available
from CDC, the Department of Housing and Urban Development,
and CMS. To the extent necessary, CDPH should enter into a
memorandum of understanding with DHCS to apply for and obtain
this funding.
To better hold local prevention programs accountable for
performing required activities, CDPH should, by June 2020,
conduct direct oversight through site visits for each of the local
prevention programs, and it should ensure that it continues to do so
at least once per contract cycle. In addition, CDPH should use the
local prevention programs’ biannual progress reports to assess local
prevention programs’ performance and provide feedback on their
strengths and shortcomings.

Chapter 3
CDPH HAS NOT DEMONSTRATED EFFECTIVE
MANAGEMENT OF THE LEAD PREVENTION PROGRAM
Chapter Summary
CDPH has failed to effectively manage a number of aspects of
the lead prevention program. For example, it has not met several
legislative requirements that would allow it and health care
providers to better identify children who need testing for lead
poisoning. In addition, it has not effectively advocated for changes
to a state law that makes it optional for laboratories to report
information CDPH needs to match lead test results to children,
thus causing a backlog of unprocessed lead test results. Finally,
CDPH has continued to use outdated information in its formula to
allocate funds to local prevention programs, resulting in differences
in the services that some local programs are able to provide to
children with lead poisoning.
CDPH Failed to Meet Several Recent Legislative Mandates
CDPH has failed to meet several legislative requirements that could
improve the identification of children who need testing for elevated
lead levels. For example, CDPH is overdue in producing a statutorily
required report on the effectiveness of the lead prevention program.
Further, it did not adhere to state law requiring it to develop
regulations by July 2019 that include its determination of factors
indicating that a child is at risk of lead poisoning, based on its
assessment of the most significant environmental risk factors. In
addition, CDPH’s failure to meet a requirement to notify health care
providers in a timely manner of the risks and requirements related
to lead poisoning may have resulted in children not receiving the
follow-up lead tests necessary to identify whether case management
services have been effective or children require further services.
CDPH Has Not Produced a Required Biennial Report
CDPH has failed to meet several legislative deadlines related to
childhood lead poisoning prevention and testing. As Table 3 shows,
one of these requirements is to post on its website a biennial
report describing the effectiveness of its case management efforts.
According to state law, this report must include information on
the number of children tested for lead poisoning, the number that
received certain case management and environmental services, the
identified sources of lead exposure, and whether those sources have
36 California State Auditor Report 2019-105
January 2020
been removed, remediated, or abated. However, CDPH did not
produce the report by the March 2019 deadline. As we discuss in
Chapter 2, the branch chief stated that CDPH was unable to meet
this deadline because it lacked the staff to do so and its branch chief
position had been vacant. However, given that CDPH had prepared
a draft of the report by March 2019, it is unclear how those factors
led to such a lengthy delay.

CDPH Could Improve the Identification of Children at Risk for Lead
Poisoning by Finalizing Its Assessment of Environmental Risk Factors
A state law effective January 2018 required CDPH to develop
regulations by July 1, 2019, identifying which factors health care
providers must consider when determining whether children
are at risk of lead poisoning, but it has not yet adopted these
regulations. The law directs CDPH, when determining the risk
factors, to consider a variety of significant environmental risks
associated with lead exposure. The current regulation—which
has not been updated since 2001—requires health care providers
to assess only one environmental risk factor. Specifically, the
current regulation requires health care providers to ask parents
or guardians if their children live in or spend considerable time
in a structure built before 1978 that has peeling or chipped paint
or that has been recently renovated. However, many cases of lead Many cases of lead poisoning
poisoning among children are caused by sources of lead exposure among children are caused by
other than lead-based paint. Although lead paint was the most sources of lead exposure other than
common source of lead exposure CDPH reported in its analysis of lead‑based paint.
188 cases of children poisoned by lead during fiscal year 2015–16,
the analysis also indicates that 95 of these children were exposed
to other sources of lead, such as cosmetics and traditional remedies
(37 children) and imported foods and spices (six children). The
current state regulation does not address these sources.
As Table 4 shows, other states address more risk factors in the
questionnaires they use to assess whether children are at risk of
lead exposure. By addressing only the age of a building—which aids
in determining whether it might contain lead paint—California’s
current regulation does not assist health care providers in
identifying children exposed to lead through other sources. CDPH’s
branch chief acknowledged the limitations of the current evaluation
requirement and indicated that CDPH failed to meet the deadline
for developing the new regulations because it lacked sufficient
feedback from stakeholders. However, CDPH did not start
soliciting this stakeholder feedback from medical providers until
mid-June 2019, less than a month before the deadline for developing
the regulations. If CDPH intended to develop the regulations by
July 1, 2019, it should have solicited this feedback from stakeholders
several months earlier.
CDPH currently anticipates submitting its regulations to the
California Health and Human Services Agency (CHHS) for review
by March 1, 2020, eight months after the deadline. This delay has
resulted in health care providers not having updated information
on the current environmental lead risk factors that they need to
consider, and possibly not detecting and treating lead poisoning in
certain children. Moreover, even after it submits these regulations
to CHHS, additional steps in the process are necessary before the
38 California State Auditor Report 2019-105
January 2020
regulations are finalized. For example, the draft regulations must be
submitted to the State’s Office of Administrative Law to commence
the formal rulemaking process. Consequently, the process will take
more time than the March 2020 date suggests. However, when
we asked CDPH when it anticipated that the regulations would
be finalized, it did not share its time frame for completing these
subsequent steps.

CDPH Has Failed to Communicate the Importance of Lead Testing to
Health Care Providers
Our review of CDPH’s data found that thousands of children did
not receive follow-up lead tests when needed. When children are
identified as having elevated lead levels, CDPH requires providers
to administer follow-up tests to determine whether they have
continued to be exposed to sources of lead even after receiving
treatment. However, as Figure 11 shows, many children are not
receiving follow-up tests on time, or at all. Without follow-up tests,
California State Auditor Report 2019-105 39
January 2020
CDPH and the local prevention programs do not know whether
treatment has been effective and whether children continue to
require care for lead poisoning.

The Legislature passed a law effective January 1, 2019, that requires
CDPH to inform all health care providers who perform periodic
health assessments of children about the risks and effects of
childhood lead exposure, as well as about testing requirements.
Despite the fact that it already had the necessary information
available when the law was passed in 2018, CDPH did not take
action to provide that information to health care providers until
August 2019. CDPH’s care management chief stated that CDPH
took additional time to address the requirement because it was
developing numerous ways to communicate with health care
providers. However, we question CDPH’s apparent lack of urgency.
In August 2019, CDPH submitted information for publication in
the Medical Board of California’s fall 2019 quarterly newsletter,
yet much of this information could have been included half a year
earlier in its spring newsletter. Further, CDPH had other resources
it could have used to communicate the required information
directly to providers, including pamphlets it already produces,
such as the one shown in Figure 12.

CDPH’s delay in informing providers of the risks and effects of
lead exposure and the requirements to test for it may result in
certain children not receiving appropriate care. State law requires
health care providers to share the information from CDPH with
parents and guardians, and the need to fulfill this requirement
seems especially crucial given the number of parents and health
care providers who fail to prioritize lead tests or do not follow
lead testing requirements. Specifically, in 10 of the 40 cases of lead Health care providers gave
poisoning we reviewed, health care providers gave incorrect incorrect information about
information about whether children needed follow-up tests or whether children needed follow‑up
administered incorrect tests. Further, parents declined to return tests or administered incorrect tests

and missed tests demonstrate the importance of CDPH promptly poisoning we reviewed.
providing the required information. Not only will the information
help educate health care providers on lead testing requirements, it
will also assist those providers in communicating the importance of
lead tests to parents.
CDPH’s Failure to Ensure That Laboratories Submit Adequate
Patient Identification With Test Results Has Led to a Backlog of
Unprocessed Cases
Despite a backlog of lead test results, CDPH has not sufficiently
advocated for changes necessary to efficiently assign lead test
results to children’s cases. CDPH must ensure that a child obtains
appropriate case management when lead test results indicate
the child has lead poisoning. When it receives test results from
laboratories, it must link that data to existing cases in its case
management system. Therefore, CDPH needs information that
clearly identifies the child tested.
According to CDPH, the system currently uses identifying
information for the test results, such as names, birth dates, and ZIP
codes from addresses, to assign lead test results to new or existing
cases. However, state law related to blood lead test reporting
requires laboratories to report birth dates and addresses only if
they have that information. If they do not have a child’s birth date,
the law allows reporting the child’s age. Similarly, the law allows
reporting a phone number when the address is not available.
However, when labs do not submit addresses or birth dates, the
case management system is sometimes unable to assign test results
to children. If the system is unable to match new test results to
existing cases, it cannot update the cases with new measurements
of blood lead levels or close the cases when test results indicate it
is safe to do so. Instead, it sends the records to a queue for manual
processing by CDPH staff.
42 California State Auditor Report 2019-105
January 2020
Since 2006 CDPH’s case management system has received
more than 9 million test results, 9.6 percent of which required
manual data processing. Test results without sufficient identifying
information have contributed to the nearly 700,000 test results
CDPH had queued in its system as of August 2019. Based on its 2018
average manual processing rate of 14 tests per day, CDPH would
need an estimated 132 years to address this backlog, even if no
additional test results were added. According to CDPH, it prioritizes
manually reviewing and assigning to cases those test results in its
queue that are above 3.3 micrograms. Our review verified that the
lead test results remaining in the queue did not include any children
with lead levels greater than this value. However, according to the
chief of care management, this backlog has limited CDPH’s and
local prevention programs’ ability to efficiently track cases and
determine the need for follow-up care, as manually searching for
tests consumes a significant amount of staff time.
Although requiring more complete identifying information would
help in assigning test results to new or existing cases, matching
tests to cases can best be accomplished with a unique identifier,
according to an epidemiologist at CDPH. She described various
unique identifiers, such as Medi-Cal identification numbers and
medical plan identification numbers, that laboratories could include
with their test results. State law allows laboratories the option
of reporting additional identifying information to CDPH, and
CDPH’s case management system has the capacity to collect such
information. However, this law does not require such reporting.
In addition, even though laboratories must review Medi-Cal
identification numbers for billing purposes, CDPH states that they
rarely submit them with test results.
CDPH’s chief of its program evaluation and research section stated
that CDPH is concerned that advocating for changes to state
law might adversely impact the information it receives because
laboratories and health care providers might advocate for less
stringent requirements in response. Nevertheless, this information

to require a unique identifier with for CDPH to prioritize advocating for legislative changes to require a

Poor data reporting by laboratories has also impeded CDPH’s
ability to contact families of children who need services. CDPH
requires contact information for children in order to provide
additional services, such as home visits and environmental
assessments. State law requires laboratories to report either phone
numbers or addresses with test results. However, laboratories
often do not submit sufficient information. Specifically, more than
California State Auditor Report 2019-105 43
January 2020
325,000 records—or 12 percent of the lead tests that laboratories
reported from July 2013 through June 2018 for children age 6 and
under—lacked both addresses and phone numbers. Requiring
laboratories to report both an address and telephone number would
improve CDPH’s ability to contact the families of children with
lead poisoning to deliver appropriate case management services.
Further, it would provide information that CDPH could use to
match lead tests to children’s records that do not have unique
identification numbers.
CDPH’s Failure to Update Its Local Prevention Program Funding
Allocation Methodology Has Led to Inequities in Allocations to
Local Programs
CDPH’s inequitable methodology for allocating funds to local
prevention programs has led to significant differences in the
level of services those programs provide to children diagnosed
with lead poisoning. Specifically, CDPH uses a formula based
on outdated data, such as the number of children with lead
poisoning in 2007. As a result, it has allocated to local prevention
programs dramatically different amounts of funding per child
with lead poisoning in their jurisdictions. According to CDPH’s
administrative section chief, it generally bases funding for the local
prevention programs on a number of factors, including an area’s
number of low-income children, its number of children in older
housing, and the number of children with lead poisoning in the
county in which the program is located. However, CDPH did not
maintain documentation specifying how or when it calculated the
proportions in which it distributes funds, so it had to recreate that
analysis in response to our request for information.
Although the standard of care for case management of children
with lead poisoning is the same regardless of where they live in the
State, one of the local prevention programs we visited explained
that its ability to provide home visits is limited by the amount
of funding it receives. We found that during the contract period
for fiscal years 2017–18 through 2019–20, the allocations to local
prevention programs did not align with the numbers of children CDPH allocated the Riverside
with lead poisoning for which the programs are responsible. For County local prevention program
example, CDPH allocated the Riverside County local prevention almost $550,000 in basic funding,
program almost $550,000 in basic funding, while it allocated the while it allocated the Sacramento
Sacramento County local prevention program—which had twice County local prevention program—
as many children with lead poisoning—only $409,000. In fact, for which had twice as many
local prevention programs with five or more such children, we children with lead poisoning—
found that the annual funding CDPH allocated varied from roughly only $409,000.
$3,000 per child with lead poisoning to more than $30,000 per
child with lead poisoning, based on CDPH’s counts of children
with lead poisoning from 2015.
44 California State Auditor Report 2019-105
January 2020
We observed differences in the levels of service provided by some
local prevention programs because of funding levels, despite
the fact that they are contracted to provide case management of
children with lead poisoning according to the same criteria. For
example, the Humboldt County local prevention program, to which
CDPH allocated the equivalent of about $3,000 in basic funding
per child with lead poisoning, performed home visits in only six of
the 10 cases we reviewed, and it averaged 1.5 visits for those cases
before their closure. It generally conducted a greater proportion
of its outreach to the families of children with lead poisoning by
telephone or letter rather than through home visits. In contrast,
the Fresno County local prevention program—to which CDPH
allocated the equivalent of more than $6,000 in basic funding per
child with lead poisoning—performed home visits for every case
we reviewed, and it visited each child eight times on average. Given
that the suggested case management is similar for the lead levels
of the children whose cases we reviewed in the two programs,
we find the differences between the levels of service the children
received troubling.
CDPH intends to continue using these funding allocations for
contracts beginning in fiscal year 2020–21 despite the disparity
in the services the local prevention programs have provided.
According to CDPH’s administrative section chief, CDPH plans
to continue using its current allocations because it anticipates
upcoming changes to the lead prevention program as a result of
the regulations it is in the process of completing to expand the
definition of environmental lead hazard risk factors. However, he
did not provide an expected completion date for these regulations.
CDPH’s continued reliance on a formula that uses outdated
information to allocate funding to local prevention programs has
contributed to children receiving unequal levels of service. CDPH
should instead create an allocation methodology that provides more
equitable funding for these programs before it executes additional
contracts with them.
Recommendations
Legislature
To support CDPH’s efforts to efficiently monitor lead test results,
the Legislature should amend state law to require that laboratories
report Medi-Cal identification numbers or equivalent identification
numbers with all lead test results.
California State Auditor Report 2019-105 45
January 2020
To ensure that CDPH can contact the families of children with lead
poisoning and has alternative information to match lead tests to the
children’s records that do not have unique identification numbers,
the Legislature should amend state law to require laboratories to
report phone numbers and addresses with all lead test results.
CDPH
To better ensure that children with lead poisoning are identified and
treated, CDPH should prioritize meeting legislative requirements
related to these issues, including doing the following by March 2020:
• Finish developing the lead risk evaluation regulations and
include in them multiple risk factors, such as those used in lead
risk evaluation questionnaires in other states. It should also
commence the formal rulemaking process.
• Provide guidance to health care providers about the risks of
childhood lead exposure and statutory requirements related to
lead testing.
To ensure a more equitable distribution of resources for treating
children with lead poisoning, CDPH should, by June 2020, update
its methodology for allocating funds to local prevention programs,
including accounting for the most recent annual count of children
with lead poisoning in each jurisdiction. CDPH should revise the
allocations before each contract cycle.
We conducted this audit under the authority vested in the California State Auditor by Government
Code 8543 et seq. and according to generally accepted government auditing standards. Those standards
require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a
reasonable basis for our findings and conclusions based on our audit objectives specified in the Scope
and Methodology section of the report. We believe that the evidence obtained provides a reasonable
basis for our findings and conclusions based on our audit objectives.

Assessment of Data Reliability
The U.S. Government Accountability Office, whose standards
we are statutorily required to follow, requires us to assess the
sufficiency and appropriateness of the computer-processed
information that we use to support our findings, conclusions, and
recommendations. In performing this audit, we relied on DHCS’
Management Information System/Decision Support System and
CDPH’s Response and Surveillance System for Childhood Lead
Exposures II (case management system) to identify when children
received blood lead tests and the results of the tests. To evaluate
these data, we reviewed existing information about the data,
interviewed agency officials knowledgeable about the data, and
performed electronic testing of the data. We identified various
limitations with the data.
Specifically, we reviewed a 2015 report from an organization
DHCS contracted with that revealed concerns with both the
completeness and the accuracy of DHCS’ data from 2012. This
report issued several recommendations to DHCS in an effort to
improve data quality, and DHCS took steps to implement these
recommendations. Further, a 2019 report from the same contractor
found that DHCS’ 2016 data were more complete and accurate
than its data from 2012, but it also found gaps in the quality of the
more recent data. However, we are unable to quantify the effect
these issues had on the data we used for this audit because we
were unable to perform completeness or accuracy testing as source
documentation was available only at individual medical providers
throughout the State, making such testing cost-prohibitive. With
respect to the case management system, as we discuss in Chapter 3,
we noted that insufficient data from laboratories, such as names,
birth dates, and unique identifiers, limits CDPH’s ability to assign
lead test results it receives from laboratories to the correct children
in its system.
As a result of these data limitations, we found that the Management
Information System/Decision Support System and case
management system data were of undetermined reliability for our
purposes. Although this determination may affect the precision
of the numbers we present, there is sufficient evidence in total to
support our findings, conclusions, and recommendations.

Appendix B
Many Children in Medi‑Cal Who Did Not Receive All Their Lead Tests Live
in the 50 Census Tracts Where Elevated Lead Levels Are Most Common
As part of this audit, we identified those geographic areas where
the largest numbers of children under age six with elevated lead
levels reside and determined for the same areas the number of
missed tests children in Medi-Cal at ages one and two should have
received. From fiscal years 2013–14 through 2017–18, the results of
lead tests for the 50 California census tracts with the most children
with elevated lead levels showed that in nine census tracts in
Sacramento County nearly 700 children under age six had elevated
lead levels, and children at ages one and two who were enrolled in
Medi-Cal in those areas missed nearly 70 percent of their required
tests. Similarly, in eight census tracts in Fresno County, children at
ages one and two in Medi-Cal missed nearly half of the required
tests (4,408 of 9,026), despite the fact that 488 children under
age six with elevated lead levels lived in those areas. Los Angeles
County also had seven census tracts among the 50 with the most
children with elevated lead levels, while Humboldt County and
Imperial County each had four, as Table B shows.

Department of Health Care Services’ Response to the California State Auditor’s
DraftReport, Childhood Lead Levels: Millions of Children in Medi-Cal Are Not
Receiving Required Testing for Lead Poisoning
Report Number: 2019-105 (19-22)
Finding 1: Department of Health Care Services’ (DHCS) Failure to Ensure Timely
Lead Testing of Children in Medi-Cal Places Them at Risk for Permanent Health
Problems
Recommendation 1
Because of the severe and potentially permanent damage lead poisoning can cause in
children, DHCS should ensure that all children in Medi-Cal receive lead tests by
finalizing, by December 2020, its performance standard for lead testing of one- and two-
year-olds. DHCS should use its existing data to assess the progress of managed care
plans in meeting that performance standard and impose sanctions or provide incentive
payments as appropriate to improve performance.
Current Status: Will Implement
Estimated Implementation Date: December 2020
Implementation Plan:
DHCS will release the first version of its Preventive Services Utilization Report (Report)
by December 2020. DHCS will seek public comment on measures that should be
included in the Report. However, it has already been determined that the Blood Lead
Screening measure will be included.
1 DHCS will utilize Medi-Cal managed care plan (MCP) administrative data to calculate
the rate of Blood Lead Screening for each MCP per National Committee for Quality
Assurance, Healthcare Effectiveness Data and Information Set, technical specifications.
The use of these nationally recognized technical specifications will allow DHCS to
compare California’s Medi-Cal MCP rates to the performance of other Medicaid plans
nationally. Furthermore, it will assist DHCS with establishing a performance standard
and utilize them to drive quality improvement. MCPs that do not meet the established
benchmark will be placed under a Corrective Action Plan (CAP). Should they not come
into compliance with the CAP, DHCS will impose sanctions and/or penalties.
2 Of note, DHCS has already implemented a Value Based Payment (VBP) Program
which incentivizes providers to conduct various activities relating to care for Medi-Cal
beneficiaries. Providers receive a payment for completion of a measure relating to said
activities. Blood Lead Screening is one of the measures.
Recommendation 2
To ensure that families know about the lead testing services their children are entitled to
receive, DHCS should send a reminder to get a lead test for children who missed
required tests. It should send this reminder in the required annual notification it is
developing to send tofamilies of children who have not used preventive services over
the course of a year.
Draft Report Response | 19-22 Page 1 of 2
California State Auditor Report 2019-105 59
January 2020
Current Status:Will Implement
Estimated Implementation Date: March 2020
Implementation Plan:
DHCS is working on a targeted outreach campaign to inform beneficiaries about the
availability of American Academy of Pediatrics (AAP)/Bright Futures services under
Medi-Cal and how to access them. Part of this outreach will include highlighting the
availability of lead testing services that children in Medi-Cal are entitled to receive.
DHCS is targeting March of 2020 to mail its first outreach notice to all beneficiaries. This
notice will be sent to all beneficiaries up to the age of 21. It will be followed by a more
targeted outreach notice which will be mailed to beneficiaries who have not accessed
preventive services during the prior twelve months. Medi-Cal MCPswill also conduct a
call campaign to follow-up with children and their families who have not used preventive
services over the course of a year, including lead testing services for children younger
than sixyears old.
Recommendation 3
To increase California’s lead testing rates and improve lead test reporting, DHCS
should, no later than June 2020, incorporate into its contracts with managed care plans
a requirementfor the plans to identify each month all children with no record of
receiving a required test and remind the responsible health care providers of the
requirement to test the children. DHCS should also develop and implement a procedure
to hold plans accountable for meeting this requirement.
Current Status:Will Implement
Estimated Implementation Date: June 2020
Implementation Plan:
By June of 2020, DHCS will submit a contractamendment to the Centers for Medicare 3
and Medicaid Services (CMS) for approval that will include a requirement for MCPsto
identify each quarter all children with no record of receiving a required lead test and
remind the responsible health care provider of the requirement to test the children.
Given CMS has a contract review and approval process, DHCS will release an All Plan
Letter establishing the MCP policy pending contract approval from CMS. DHCS will
review heath plan policies and procedures to ensure MCP compliance with the policy.
DHCS will also review the MCP process related to this contractual requirement during
its annual medical audit, and impose a CAP if non-compliance is identified. Since the
DHCS annual medical audit is a one year retrospective audit, the DHCS will begin
auditing this policy in July 2021.

CALIFORNIA STATE AUDITOR’S COMMENTS ON
THE RESPONSE FROM THE DEPARTMENT OF
HEALTH CARE SERVICES
To provide clarity and perspective, we are commenting on DHCS’
response to our audit. The numbers below correspond to the
numbers we have placed in the margin of DHCS’ response.
DHCS’ plan does not address our recommendation to finalize 1
its performance standard for lead testing of both one- and
two-year-olds. The technical specifications it refers to measure
only the percentage of two-year-olds who had at least one test by
their second birthday. As we state on page 17, state regulations,
with few exceptions, require health care providers to administer
tests for elevated lead levels for both one- and two-year-old
children. Thus, the plan DHCS describes will not be effective in
determining whether children have received the tests required
by the regulations.
DHCS’ statement that it has already implemented a value-based 2
payment program for lead testing contradicts information it
provided during the audit. Specifically, as we state on page 22, as
of September 2019 DHCS had not yet determined when it would
begin making payments for lead testing. We look forward to DHCS
informing us when it begins making payments for reported lead
tests under this program.
Although DHCS’ plan for notifying health care providers would 3
be an improvement from its current practice, we believe that it
should include in its contracts the requirement to identify these
children and remind the responsible health care providers each
month, rather than each quarter. As we describe on page 17,
state regulations generally require children in Medi-Cal to be
tested at ages one and two. Further, as we explain on page 5 in
the Introduction, children at this age are especially vulnerable to
lead exposure. Because delays in testing may result in additional
exposure for children who have lead poisoning, and due to the
relatively limited age range during which these tests should be
conducted, we believe that providing this information on a monthly
basis is in the best interests of a child’s health.

Comments
CALIFORNIA STATE AUDITOR’S COMMENTS ON THE
RESPONSE FROM THE CALIFORNIA DEPARTMENT OF
PUBLIC HEALTH
To provide clarity and perspective, we are commenting on CDPH’s
response to our audit. The numbers below correspond to the
numbers we have placed in the margin of CDPH’s response.
CDPH has organized its response by summarizing the findings and 1
conclusions described in our report. Its descriptions of the findings
do not precisely correspond to the text of the report.
CDPH responded to several issues in our report by citing actions it 2
asserts are reported in its draft biennial report. As we describe on
page 28, CDPH informed us during the audit that it completed the
draft report in March 2019 but had not approved the report as of
October 2019. CDPH asserts that its draft report is confidential, and
because we cannot discuss this draft report we are unable to verify
or dispute CDPH’s claims.
CDPH overgeneralizes in its assertion that it has implemented a 3
program of medical follow-up and environmental abatement that
has reduced the incidence of excessive childhood lead exposures
in California. As we state on page 49, CDPH assesses the progress
it has made toward eliminating lead poisoning by tracking the
percentage of children tested who had elevated lead levels over
time. Although the number of children with elevated lead levels has
varied from year to year, as Table 1 on page 7 shows, from calendar
years 2015 to 2017 the number of children with elevated lead levels
has increased. Further, as we reference on page 49, during the past
five years these percentages have not consistently decreased.
CDPH did not provide evidence to support its assertion that it 4
targets areas at high risk for lead exposure. Specifically, as we state
on page 27, although state law requires annual analysis to identify
geographic areas at high risk for lead exposure, CDPH’s most recent
update to its list of high-risk geographic areas was based on 2015
data. Thus, it follows that it does not have up-to-date information to
use in targeting areas of high risk for reducing lead exposure. As we
describe on page 30, CDPH’s lead hazard reduction chief stated that
CDPH’s approach to abating lead in high-risk areas is to monitor
abatement activities in the homes of children who have already
been poisoned.
CDPH’s response does not address our concern that it does not 5
know whether its outreach has reduced instances of lead poisoning.
As we state on page 30, neither CDPH nor the local prevention
72 California State Auditor Report 2019-105
January 2020
programs we reviewed measure the effectiveness of their outreach
activities in reducing the number of children with lead poisoning.
Evaluating the effectiveness of outreach by measuring changes
in knowledge and behavior such as increased handwashing and
increased screening, as CDPH suggests it will do, will not establish
whether these efforts have reduced the number of children with
lead poisoning.
6 We disagree with CDPH’s perspective that it is more effective for
local agencies to apply for funding to perform abatement. As we
describe on page 32, CDPH stated that one of the reasons it has
not applied for these funds is that it would be competing with local
jurisdictions for the funding. CDPH’s branch chief also told us that
it is inefficient for multiple agencies to apply for the same funds.
However, as we state on page 32, we believe that CDPH could more
efficiently facilitate the distribution of such funding if it were to
apply for the funds and pass them on to local programs, rather than
have the local prevention programs expend resources competing
against each other. Further, we did not recommend that CDPH
perform abatement work directly, as CDPH implies. Nevertheless,
because of its role in providing oversight of the statewide lead
prevention program, and because a state agency is better equipped
to apply for these federal funds, CDPH is best suited to seek out
and apply for additional lead prevention funding to offset the cost
of mitigating lead exposure in the highest-risk areas of the State,
identify areas of the State with the highest need for such funds, and
allocate them to the local prevention programs as appropriate.
7 CDPH’s response is confusing. We do not suggest that CDPH is
better suited to address local needs, enforce local laws, or enforce
the cleanup of lead hazards. Rather, we are suggesting that CDPH
obtain funds from federal sources and make them available to local
prevention programs to use for lead abatement activities.
8 Notwithstanding CDPH’s description of the experiences of other
states using CMS funding, we believe that any opportunity to
prevent lead poisoning without cost to the State is of value.
Therefore, we stand by our recommendation that CDPH should
seek out and apply for additional lead prevention funding.
9 CDPH misinterprets our recommendation. As we state on
page 33, CDPH should report information only to the extent that it
can ensure that it does not make personally identifying information,
including medical information, public. Thus, development of an
online lead information registry in this manner would not result
in the disclosure of confidential information. As we describe on
page 33 of our report, CDPH will need to take steps to ensure that
it does not make information available to the public that could
be used to identify individuals in its case management system.
California State Auditor Report 2019-105 73
January 2020
Therefore, it is unclear why CDPH asserts that implementing this
recommendation would result in the disclosure of confidential
information related to the addresses of children with lead
poisoning. Further, as we state on page 32, CDPH indicates that
it receives lead inspection and abatement information on tens of
thousands of properties every year. CDPH’s lead hazard reduction
chief also informed us that only 1 percent of these records are
related to the addresses of children with lead poisoning. As a
result, CDPH could make public the majority of the abatement and
inspection information it has collected without risk of disclosing
confidential health information.
CDPH’s statements are irrelevant to our conclusions and 10
recommendations. Our report does not suggest that a record
of an abatement means that there is no lead on the property, or
that it represents a guarantee that lead hazards could not exist in
the future. Specifically, we state on page 32 that such registries
can provide information on whether and when a property was
inspected for lead, and the status of any identified lead hazards.
Therefore it is unclear why CDPH implies that reporting such
information as a short-term abatement status would limit the
usefulness of providing this information to the public.
CDPH’s suggestion that it cannot mask forms related to children 11
with lead poisoning is not relevant to our recommendation. Our
recommendation does not suggest that CDPH post forms in the
registry. Rather, as we recommend on page 33, CDPH should
make public the information it already maintains to the extent it
can ensure that it does not make personally identifiable medical
information public.
CDPH did not present the full text of this recommendation. As 12
page 33 shows, our recommendation includes the following text:
“To accomplish this task, CDPH should use the information it
already maintains only to the extent that it can ensure that it does
not make personally identifying information, including medical
information, public.”
CDPH chose to respond to this recommendation even though we 13
directed it to the Legislature. Nevertheless, CDPH’s proposal to
provide guidance to the public on how to request information for
specific addresses instead of reviewing an online registry would
be inconvenient and time-consuming. Further, as we describe on
page 32 of our report, state regulations already require CDPH to
collect lead inspection and abatement information. Moreover,
creating such a registry should not be an overly burdensome
process. As we described to CDPH during the course of our audit,
74 California State Auditor Report 2019-105
January 2020
our office was able to create a working model of such a registry
in less than a day using a copy of CDPH’s database that contains
this information.
14 CDPH asserts that it assesses local prevention programs’
performance through site visits and biannual progress reports, but
it has not done so for all local prevention programs. As we describe
on page 31 of the report, CDPH has failed to perform a majority
of the site visits in its current contract cycle as its existing policy
requires. Further, as we describe on page 31, we have concerns that
CDPH is not sufficiently addressing performance when reviewing
the progress reports.
15 CDPH has not presented the full text of this recommendation. As
page 34 shows, our recommendation includes the following text: “In
addition, CDPH should use the local prevention programs’ biannual
progress reports to assess local prevention programs’ performance
and provide feedback on their strengths and shortcomings.”
16 The activities that CDPH describes in its response are not specific
to the legislative requirements our recommendation addresses.
As we state on page 39, the Legislature passed a law effective
January 1, 2019, requiring CDPH to notify all health care providers
who perform periodic health assessments of children of the risks
and effects of childhood lead exposure, as well as the testing
requirements. None of these efforts that CDPH describes, which we
reviewed during the course of our audit, ensures that all health care
providers who perform periodic health assessments for children
received this information, as the law requires. Further, as we state
on page 39, CDPH already had resources it could have used to
communicate the required information directly to providers when
the law was passed in 2018.
17 CDPH’s statement that it introduced different allocation methods
is inaccurate. Despite increasing the amounts paid to local
prevention programs, CDPH allocated the amounts using the
same proportions as before. We look forward to reviewing the
information that CDPH provides regarding the equity of its funding
allocation mechanism in its follow-up responses to the audit.
18 We do not suggest in the report that children with elevated lead
levels have gone without any case management due to unavailable
funding. Rather, as we describe on page 44, the level of services
provided by the local prevention programs that we reviewed differ
because of different funding levels. Specifically, we found that the
annual funding CDPH allocated to local prevention programs using
its current methodology varied from about $3,000 per child with
California State Auditor Report 2019-105 75
January 2020
lead poisoning to more than $30,000 per child with lead poisoning.
These dramatic differences in funding levels highlight the effect of
CDPH’s use of its current funding methodology.
We discussed our conclusions about the Humboldt program 19
with CDPH on multiple occasions, but CDPH did not request
information about the cases we reviewed.
CDPH’s statement that parents have the right to refuse services 20
does not change our conclusion that CDPH’s inequitable method
of allocating funds has led to differences in the level of services
provided. As described on page 43, we determined that the amount
of funds allocated to local prevention programs did not align
with the numbers of children with lead poisoning for which the
programs are responsible. Further, the Humboldt County local
prevention program explained that its ability to provide home
visits is limited by the amount of funding it receives. As we state
on page 44, our review determined that in those cases where it
performed a home visit, the Humboldt program provided fewer
visits on average than the Fresno County local prevention program,
which received the equivalent of twice the funding per child with
lead poisoning.
CDPH’s statement regarding removing children from their families 21
and entering homes without consent is unrelated to the text of our
report and the nature of our recommendations. At no point did we
recommend that CDPH should remove children from the homes
of their parents, nor did we advocate for or against parents’ right to
refuse services.
