INTRODUCTION: This study aimed to define risk factors associated with inpatient mortality in @entity1 undergoing elective repair for unruptured @entity1028 and utilize these factors to create a scoring system to estimate risk of mortality. METHODS: A retrospective analysis was completed using the Nationwide Inpatient Sample from 1998 to 2011. @entity1 who underwent elective @entity1028 repair were identified using ICD-9 codes. Demographics, comorbidities, length of stay, insurance status, and mortality were recorded. Statistically significant variables were identified using a multivariate analysis, and a discriminant analysis was used to identify factors predictive of inpatient mortality. RESULTS: Over a 14-year period, 28,448 @entity1 underwent elective repair of an unruptured @entity1028 . Independent variables associated with inpatient mortality included: age >60, female gender, congestive @entity712 , peripheral @entity455 , @entity177 , @entity3147 , and @entity49 . @entity439 repair was protective against inpatient mortality. The area under the curve for the discriminant function was 0.83 (95% CI, 0.81-0.85) and successfully classified 87.9% of @entity1 within the Nationwide Inpatient Sample (25,006/28,448 @entity1 ). CONCLUSION: Seven factors that predict an increased risk of mortality and one factor that decreased the risk of mortality were identified. Preoperative risk factor mitigation may improve mortality following elective @entity1028 repair.
