Antipsychotic Use Among Nursing Home Residents, Becky Briesacher, Jennifer Tjia, Terry Field, Daniel Peterson, Jerry Gurwitz

Jennifer Tjia

The prescribing of antipsychotic medications persists at high levels in US nursing homes (NHs) despite extensive data demonstrating marginal clinical benefits and serious adverse effects, including death.1- 2 However, imprecise and outdated data have limited the understanding of the current state of antipsychotic medication prescribing in NHs.3 We analyzed recent and detailed NH prescription data to address: (1) What is the current level of antipsychotic use? (2) Does antipsychotic use in NHs display geographic variation? and (3) Which antipsychotics are most commonly prescribed?

Perceptions Of Evidence-Based Programs Among Community-Based Organizations Tackling Health Disparities: A Qualitative Study, Shoba Ramanadhan, Josephine Crisostomo, Jaclyn Alexander-Molloy, Ediss Gandelman, Milagro Grullon, Vilma Lora, Chrasandra Reeves, Clara Savage, Kasisomayajula Viswanatha, Chyke Doubeni

Chyke A. Doubeni

Dissemination of prevention-focused evidence-based programs (EBPs) from research to community settings may improve population health and reduce health disparities, but such flow has been limited. Academic-community partnerships using community-based participatory research (CBPR) principles may support increased dissemination of EBPs to community-based organizations (CBOs). This qualitative study examined the EBP-related perceptions and needs of CBOs targeting underserved populations. As part of PLANET MassCONECT, a CBPR study, we conducted six key informant interviews with community leaders and four focus groups with CBO staff members in Boston, Worcester and Lawrence, Massachusetts, in 2008. Working definitions of EBPs among CBO staff members varied greatly …

The Associations Between Victimization, Feeling Unsafe, And Asthma Episodes Among Us High-School Students, Monica Swahn, Robert Bossarte

Monica H. Swahn

We examined the associations between victimization, missed school because of feeling unsafe, and asthma episodes among US high-school students using the 2003 Youth Risk Behavior Survey. Cross-sectional analyses on adolescents with asthma (n=1943) showed that any victimization and missed school because of feeling unsafe significantly increased the odds of having an asthma episode in the past year (adjusted odds ratio [OR]=1.45; 95% confidence interval [CI] = 1.07, 1.95 and adjusted OR = 2.93; 95% CI = 1.90, 4.53, respectively). Victimization and feeling unsafe are important but poorly understood risk factors for asthma.

Insurance Status And Length Of Stay For Involuntarily Hospitalized Patients, William Fisher, Paul Barreira, Alisa Lincoln, Lorna Simon, Andrew White, Kristen Roy-Bujnowski, Marylou Sudders

Alisa Lincoln

General and private psychiatric hospitals are becoming increasingly common as sites for involuntary hospitalization. Unlike the public facilities that these settings are supplanting, these hospitals must pay strict attention to issues associated with reimbursement, insurance status, and managed care. This article examines the effects of insurance status on length of stay for involuntarily hospitalized patients in general and private hospitals in Massachusetts. Using a two-stage sampling procedure, data on episodes of involuntary hospitalization were gathered and assessed using multiple regression. The primary effect was found between patients with Medicare, who had the longest stays, and individuals who were uninsured, who …
