Although predictors of hospital-acquired VTE are well-known, triggers of VTE before hospitalization are not as clearly defined. The objective of this study was to evaluate triggers of hospitalization for VTE. METHODS AND RESULTS: A case-crossover study was conducted.

The study differs from previously published analyses of this issue in that it deals with the current Medicare risk program (TEFRA) rather than with earlier Demonstration… Continue reading Selection bias in TEFRA at-risk HMOs
Behavioral adaptation and late-life disability: a new spectrum for assessing public health impacts
OBJECTIVES: To inform public health efforts to promote independent functioning among older adults, we have provided new national estimates of late-life disability that explicitly recognize behavioral adaptations. METHODS: We analyzed the 2011 National Health and Aging Trends Study, a study of Medicare enrollees aged 65 years and older (n = 8077). For 7 mobility and… Continue reading Behavioral adaptation and late-life disability: a new spectrum for assessing public health impacts
