Warranties And Reimbursements For Family Caregivers Provide Alternative Payment Methods
The New York Times reports on a proposal for a new health care reimbursement model that offers warranties to patients, a topic also examined in a piece by Francois de Brantes in the journal, Health Affairs. Brantes and co-authors developed a model, called the Prometheus Payment, which offers set fees to providers that "cover all recommended services, treatments and procedures for specific conditions but are also "risk-adjusted" for patients who may be older or frail. The warranty is based on the costs incurred by avoidable complications. In current fee-for-service plans, all costs from these complications are covered by the third party payer, regardless. But in the Prometheus Payment model, half of the costs from avoidable complications must be paid for by the providers themselves. The result, Mr. de Brantes and his co-authors write, is a payment system that offers patients a health care warranty, since "providers win or lose financially based on their actual performance in reducing the incidence of avoidable complications.""

Fathers Respond To Teens' Risky Sexual Behavior With Increased Supervision

Two-thirds of American teenagers have sex by the time they"re 18. A new longitudinal study finds that when adolescents engage in risky sexual activity, fathers respond by increasing their efforts to supervise and monitor their children. Researchers at Boston College, the University of Pittsburgh, and Harvard University conducted the study, which appears in the May/June 2009 issue of the journal Child Development. The study followed more than 3,200 teenagers ages 13 to 18 over a period of four years. The teens were a subset of participants in the National Longitudinal Survey of Youth, a representative sample of American adolescents. Each year, the teens reported on their parents" knowledge of their activities, friends, and so forth. Starting at age 14, the teens also answered questions about their engagement in risky sexual activities, including frequency of intercourse, number of partners, and incidences of unprotected intercourse. The study suggests that fathers react differently than mothers to their children"s sexual behavior. When teens engaged in risky sexual behavior, instead of parents becoming less involved, as previously seen, fathers boosted their involvement, learning more about their children"s friends and activities. This finding contradicts previous research, which has found that parents react with hostility and are less engaged following such discoveries. This study also identified involvement in family activities as a protective force. Specifically, it found that teens who took part in routine family activities like eating meals together or joining in fun projects were less likely to engage in risky sexual activity, and teens who didn"t engage in risky sexual behavior were more likely to participate in family activities. "This research highlights the complex interplay of relationships between parents and their adolescent children," according to Rebekah Levine Coley, associate professor of applied developmental and educational psychology at Boston College and the study"s lead author. "Given the notably negative potential repercussions of risky sexual activity during adolescence, this study can inform efforts to increase parents" oversight of and active engagement with their teenage children." The study was funded, in part, by the Eunice Kennedy Shriver National Institute of Child Health and Human Development.
