1. INITIATIVE LAUNCHED TO HELP STRENGTHEN PUBLIC HEALTH PREPAREDNESS
FOR PANDEMIC INFLUENZA
Promising Practices: Pandemic Preparedness Tools aims to enhance public
health preparedness for an influenza pandemic and conserve resources by
sharing promising practices. The initiative, conceived by the Pew
Charitable Trusts, was launched to collect and review practices that
can be adapted or adopted by public health stakeholders. Materials were
submitted chiefly via survey to state and local experts in pandemic
influenza preparedness, and they underwent a peer-review process. The
current collection represents a year-long effort and includes more than
130 practices in the following categories and focus areas: models for
care (surge capacity, standards of care, triage strategies,
out-of-hospital care, collaborations); communication (risk
communications, community engagement, resiliency); and mitigation
(social distancing). Reviewers' comments have been incorporated into a
project description to provide a more complete context for each
practice. Practices may also be searched by language, personal
preparedness, vulnerable populations, home care, school toolkits,
ethics projects, other toolkits, and state. More information, including
instructions on submitting a practice, is available at http://pandemicpractices.org.

2. SUPPLEMENT EXAMINES INFLUENCES ON OBESITY AMONG ADOLESCENTS AND
HEALTHY ADOLESCENT BEHAVIOR
The October 2007 supplement to the American Journal of Preventive
Medicine examines the impact of the policies, programs, practices, and
other environmental influences on obesity among adolescents. The
supplement includes an introduction and 11 papers containing some of
the first findings from research supported by the Robert Wood Johnson
Foundation (RWJF) on the environmental determinants of obesity among
adolescents and on the physical inactivity and poor dietary practices
that contribute to the problem. The introduction to the supplement briefly
describes RWJF's Bridging the Gap (BTG) initiative and the surveys and
other data sets from which it has drawn its data; highlights some of
the initiative's research on adolescent substance abuse to illustrate
its potential for parallel contributions to the childhood obesity
issue; and discusses the conceptual framework that underlies BTG's more
recent work on youth physical activity, healthy eating, and obesity.
The papers that follow emphasize the disparities that exist in these
factors and outcomes among different racial and ethnic and
socioeconomic groups. Two papers from the National Cancer Institute's
related efforts to identify, rate, and track state policies potentially
affecting these behaviors are also included. The supplement is
available at http://www.ajpm-online.net/issues/contents?issue_key=S0749-3797(07)X0129-6.

3. ANALYSIS MEASURES ASSOCIATION OF MATERNAL EDUCATION LEVEL AND
CHILDHOOD IMMUNIZATION RATES AMONG STATES
"We have demonstrated in a nationally representative probability sample
. . . a direct monotonic relationship between the level of maternal
education and the probability of children being up-to-date for vaccine
receipt," state the authors of an article published in the October 2007
issue of Social Science and Medicine. Research has shown that higher
levels of maternal education are associated with better child health
outcomes, although explaining how this correlation develops and is
maintained remains an elusive research goal. An improved understanding
of this relationship will enable policymakers to design more successful
interventions to help narrow existing socioeconomic health disparities
in children. The article examines the relationship between maternal
education level and the receipt of childhood vaccinations.
Pooled data from the National Immunization Survey (NIS) provided
information on receipt of vaccines for a national probability sample of
children ages 19-35 months. Outcomes of interest included whether a
child was up to date for the 4:3:1:3:3 series and the pneumococcal
conjugate series. The NIS also provided information on the highest
grade that the index child's mother ever completed, as well as state of
residence. The researchers stratified the level of maternal education
into four categories (less than high school, high school degree, some
college, and college degree or higher) and designated states as
universal (provide free vaccines to all residents) or non-universal
(established a limited entitlement to purchase and distribute vaccines
for a specific target population of children). The definitions of
universal and non-universal were adjusted depending upon the year of
data and the vaccine series being analyzed (for the period 1995-2005
for the 4:3:1:3:3 series and for the period 2001-2005 for the
pneumococcal vaccine). The analyses generated estimates of the
independent effect of maternal education on up-to-date status,
controlling for race and ethnicity, income, child age, family size, and
state, as well as year fixed effects.
The authors found that
- Relative to children of women with a college degree, children of
women with less than a high school education were 7.1% less likely to
be up to date for the 4:3:1:3:3 series, and those of women with a high
school degree were 4.6% less likely to be up to date.
- Children of women with less than a high school education were
2.4% less likely to be up to date for the pneumococcal conjugate
vaccine than were children of women with a college degree, controlling
for all other covariates.
- Although all states manifested negative maternal education
gradients for pneumococcal vaccine up-to-date status, those gradients
were significantly attenuated by residency in a universal state.
"Designing effective policies to maximize vaccine distribution and
acceptance is an important public health priority given the potential
returns on such an investment in knowledge," state the authors. They
conclude that "how we understand both the magnitude of the maternal
education effect on choices that influence child health and the
mechanisms by which maternal education exerts its impact will play an
important role in these policy deliberations."

4. ARTICLE EXPLORES THE ASSOCIATION BETWEEN MEDICAID MARKET
CHARACTERISTICS AND ADVERSE MEDICAL EVENTS FOR HOSPITALIZED CHILDREN
"We find that, at the market level, the concentration of Medicaid
managed care payers is positively related to the occurrence of an
adverse event for hospitalized children," write the authors of an
article published in the October 2007 issue of HSR: Health Service
Research. In 1999, an Institute of Medicine report estimated that
preventable medical errors were responsible for between 44,000 and
98,000 deaths and that the total cost of preventable errors was as high
as $17 billion, or approximately 2% of health care expenditures.
Attention to patient safety in hospitals has focused largely on adult
populations. However, while children are disproportionately
underrepresented as hospitalized patients, approximately 40% of all
pediatric hospitalizations are charged to public insurance programs,
primarily Medicaid (compared with only 17% of adult hospitalizations
that are charged to Medicaid). In the study described in this article,
the authors examine whether consolidation in Medicaid-payer markets is
associated with preventable medical error in hospitalized children,
using a measure they developed for their study.
The authors used two Agency for Healthcare Research and Quality (AHRQ)
pediatric specific safety indicators (PSIs; decubitus ulcers and
laceration) and conducted an analysis using a new, pediatric-specific,
risk-adjusting, patient-safety algorithm from AHRQ. Study participants
included all pediatric hospital discharges from birth through age 17 in
Florida, New York, and Wisconsin for which either of these two adverse
events could occur.
The authors found that
- The rate of preventable adverse events in hospitals is at least
an order of magnitude lower for children than for adults.
- Overall, patients enrolled in Medicaid experienced two fewer
preventable adverse events than privately insured patients for every
10,000 discharges of each type of patient at risk.
- At the hospital level, there is a pattern of hospitals that
reflect higher Medicaid service levels, either in terms of the
proportion of Medicaid patients or the amount of disproportionate share
hospital (DSH) payments received, having higher PSI rates. (DSH
payments are supplemental state and federal funds intended to reduce
the financial burden of hospitals treating large numbers of individuals
who are uninsured or who are covered by Medicaid.)
- Also at the hospital level, in Medicaid-payer markets, the
difference in PSI rates between concentrated and unconcentrated markets
is much smaller, and in no case is the difference statistically
significant. However, there are statistically significant higher PSI
rates in markets with relatively high vs. low enrollment in Medicaid
health-maintenance organizations (HMOs).
- At the market level, the odds of experiencing a preventable
adverse medical event are 60% higher in a concentrated vs.
unconcentrated Medicaid-payer market. In contrast, hospital
concentration tends to be protective against adverse events.
- Also at the market level, neither Medicaid HMO enrollment nor
overall HMO penetration is statistically significant. There is also no
statistically significant relationship among the discharge-level or
hospital-level Medicaid variables.
The authors caution that "while our analysis reveals a clear link
between Medicaid market concentration and pediatric patient safety, the
cross-sectional framework of our analysis does not explain the
mechanism by which they are related." However, they conclude, "our
findings point to a factor -- the Medicaid market -- that policy makers
have heretofore not generally considered in their efforts to improve
pediatric safety."
