Background  Medicare Part D excludes benzodiazepine medications from coverage, and some state Medicaid programs also limit coverage. We assessed whether such policies decrease the risk of fractures in elderly individuals living in nursing homes.

Methods  This is a quasi-experimental study with interrupted time-series estimation and extended Cox proportional hazards models comparing changes in outcomes before and after implementation of Medicare Part D in a nationwide sample of nursing home residents in 48 states. The study included 1 068 104 residents and a subsample of 50 874 residents with fracture data from 1 pharmacy. We assessed monthly prescribing rates of benzodiazepines and potential substitutes from January 1, 2005, through June 30, 2007, and hazard ratios for incident hip fracture and falls, adjusted for age, sex, and race/ethnicity. Estimates were stratified by concurrent Medicaid limits on benzodiazepines: no supplemental coverage (1 state), partial supplemental coverage (6 states), or complete supplemental coverage (41 states).

Results  The no-supplemental-coverage policy resulted in an immediate and significant reduction of 10 absolute points in benzodiazepine use (27.0% to 17.0%) after Medicare Part D was implemented (95% confidence interval, –0.11 to –0.09; P < .001). Benzodiazepine use remained stable in the partial-supplemental- and complete-supplemental-coverage states. Hazard ratios for incident hip fracture were 1.60 (95% confidence interval, 1.05 to 2.45; P = .03) in the no-supplemental-coverage state after Medicare Part D implementation and 1.17 (95% confidence interval, 0.93 to 1.46; P = .18) in the partial-supplemental-coverage states, relative to complete-supplemental-coverage states.

Conclusion  Supplemental drug coverage exclusion policies affect the medication use of nursing home residents and may not decrease their fracture risk.
