INTRODUCTION: The in-hospital mortality rate after @entity348 ( @entity348 ) is unknown. The purpose of this study is to quantify the in- @entity1 mortality rates and associated demographic risk factors for @entity1 undergoing a @entity348 from 2005 to 2011 using a comprehensive Medicare registry database. MATERIALS AND METHODS: We conducted a retrospective review of the Medicare database within the PearlDiver database. The PearlDiver database is a publicly available Health Insurance Portability and Accountability Act-compliant national database that captures 100% of the Medicare hospital data for @entity348 between 2005 and 2011. Using International Classification of Diseases, Ninth Revision codes for @entity348 we identified a dataset of @entity1 undergoing @entity348 as well as a subset of those for whom there was a @entity204 discharge (i.e., in- @entity1 @entity204 ). Risk for this outcome was further quantified by age, gender and year. Linear regression was performed to identify risk factors for the primary outcome. RESULTS: A total of 101,323 @entity1 underwent 125,813 TSAs between 2005 and 2011. There were 113 in- @entity1 mortalities during this period. Thus the incidence of @entity204 was 0.09%. Increasing age was a significant risk factor for mortality (P = 0.03). Gender and year of procedure were not significant risk factors for mortality. CONCLUSION: The incidence of in- @entity1 mortality for Medicare @entity1 undergoing @entity348 between 2005 and 2011 was <1 in 1000 surgeries. Increased age is a significant predictor of mortality. LEVEL 4: Retrospective analysis.
