HealthSpark 2: Improving Asthma Care for Preschool Children

Asthma is the most common chronic health problem affecting children in the U.S., and it is
getting worse. Children under the age of 18 years account for one third of the nation's
asthma sufferers. The percent of children with asthma has increased from 3% in 1981 to 6% in
2003. Asthma is a leading reason for hospitalizations of children under the age of 15 years
and causes 14 million days of missed school each year. Previous studies suggest particularly
high asthma rates among Hispanic and African-American populations. Poverty, increased
exposure to indoor allergens, low education level, poor access to healthcare, and failure to
take prescribed medicines increase the likelihood of having a severe asthma attack, or dying
of asthma.

According to the results of HealthSpark I, children in the target communities have rates of
asthma that are more than three times the national average. 29.3% of HealthSpark families
with children ages 3 to 5 years responded "yes" to the question, "Did a doctor ever tell you
that your child has asthma?" In a national survey in 2002, only 7.3% of parents with
children ages 0 to 4 years responded "yes" to the same question. The high rate of asthma
among HealthSpark families is similar to recent reports of high prevalence in Harlem, NY,
and other underserved, minority communities.

Of HealthSpark parents reporting that their child has asthma, 38.7% also reported that their
child was taking a medication regularly for more than a year. It is reasonable to assume
that most of these were asthma medications, which suggests that approximately 11.3% of the
total HealthSpark population has moderate to severe asthma. These children also had high
rates of comorbidity. HealthSpark children with asthma were twice as likely as children
without asthma to be limited in their daily activities, and three times as likely to require
increased medical, educational, and mental health services. HealthSpark children with asthma
were also two to three times as likely than children without asthma to have early signs of
attention deficit hyperactivity disorder (ADHD).

Our analysis also revealed ethnic differences in asthma prevalence consistent with national
patterns. African American children were nearly twice as likely to have a diagnosis of
asthma when compared with Hispanic children (40.6% vs. 23%). None of these findings were
related to access to child health care. Children with asthma, in fact, had better access to
care than children without asthma, as demonstrated by the following measures: having a
regular source of care (99.4% vs 91%), having health insurance (92.5% vs. 88.6%), and having
a regular doctor that their parents could name (94.0% vs. 86.5%). Children with
moderate/severe asthma had even better access to care: 98.4% of parents could name their
physician and 97% had health insurance for their child.

In 1989, the National Asthma Education and Prevention Program (NAEPP) was initiated by the
National Heart, Lung, and Blood Institute (part of the NIH) to address the growing problem
of asthma in the United States. To accomplish these broad program goals, the NAEPP works
with intermediaries including major medical associations, voluntary health organizations,
and community programs to educate patients, health professionals, and the public. The
ultimate goal of the NAEPP is to enhance the quality of life for patients with asthma and
decrease asthma-related morbidity and mortality. As part of this broad program, the NHLBI
released guidelines for CCCs to provide optimal care for children with asthma. These
"asthma-friendly" guidelines are at the core of this proposal.

This project is a community-based intervention to begin to improve asthma care among these
preschool children. The target population is 2000 children aged 1-5 years who attend the 51
child care centers that remain as part of the SPARK network.

The long-term goals of this project are to (a) improve the health of children by improving
asthma care in the targeted, underserved areas of Miami-Dade County and (b) to enhance
readiness for school by reducing the burden of asthma and related conditions.

The specific objectives for this project are:

1. Document the prevalence, severity, and impact of asthma among preschool children
attending the 51 SPARK child care centers (CCCs) in Allapatah/Model City and
Homestead/Florida City.

2. Identify barriers to optimal asthma care in these children.

3. Determine how "asthma-friendly" each child care center is according to guidelines of
the National Heart, Lung, and Blood Institute (part of the NIH) (see Appendix I).

4. Work with CCCs and community health clinics to improve clinical outcomes for children
with asthma.

Outcomes

1. We will better understand the prevalence, severity, and impact of asthma among
preschool children in underserved communities (parent surveys).

2. We will identify barriers to optimal, community-based asthma care projects (parent
surveys and CCC survey).

3. We will increase the number of CCCs that are "asthma-friendly" (CCC surveys, site
visit).

4. We will improve clinical outcomes for children with asthma (parent survey).

5. We will increase the number of children with written asthma plans from an estimated 10%
to greater than 50%.

Other outcomes:

Baseline correlations to identify significant relationships among individual characteristics
including asthma severity, healthcare utilization, healthcare access, comorbidity, quality
of life, environmental exposures, maternal health literacy, and maternal education
