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
"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 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."
