Effects of Medicare Part D implementaGon in the long-term care seIng: a systemaGc review Opportunity Background Medicare Part D is a voluntary prescripGon drug benefit implemented in 2006 to improve access to medicaGons to all Medicare enrollees, including those residing in long term care faciliGes. Long-term care residents, however, may have special medicaGon needs since they take more medicaGons, have a higher rate of chronic condiGons, and have more cogniGve impairments. Knowledge regarding the effect that this program has had on long term care residents is sGll relaGvely sparse.
Goal
To evaluate the current literature regarding Medicare Part D, with a focus on the effects that Part D coverage restricGons have on drug classes commonly prescribed in the long-term care seIng.

Results
Eight arGcles met inclusion criteria and were included in this systemaGc review. Part D implementaGon provided sufficient coverage and resulted in a relaGvely low number of rejecGons and uGlizaGon management requirements, but residents who did face coverage restricGons had lower medicaGon conGnuaGon rates and increased medicaGon changes or gaps in use than those without restricGons. There was a decrease in the use of Part D excluded drugs deemed unsafe for elderly, but also an indirect increase in negaGve clinical outcomes. Figure 1.

55 abstracts reviewed 36 articles excluded after abstract review • Not NH/LTC setting specific (n=9) • Not related to Part D outcomes (n=11) • No medication related outcomes (n=6) • Reviews, opinions, commentary, surveys, news articles (n=8) • Not U.S. based study (n=2)
Approach Methods
Relevant arGcles were idenGfied through a Medline search for literature published between January 2006 and July 2016 and a combinaGon of search term were used to limit search results. Search terms included “medicaGon insurance” or “Part D” and “nursing home(s)” or “long term care.” ArGcles that included these search terms were further evaluated for inclusion and exclusion criteria. Eligible arGcles were then fully reviewed for data extracGon. References
