BACKGROUND: The purpose of the present study is to use a statewide, population-based data set to identify mortality rates at 30-day and 1-year postoperatively following @entity572 ( @entity572 ) and hemiarthroplasty (HA) for displaced @entity2249 . The secondary aim of the study is to determine whether arthroplasty volume confers a protective effect on the mortality rate following @entity2249 treatment. METHODS: New York's Statewide Planning and Research Cooperative System was used to identify 45 749 @entity1 older than 60 years of age with a discharge diagnosis of @entity2249 undergoing @entity572 or HA from 2000 through 2010. Comorbidities were identified using the Charlson comorbidity index. Mortality risk was modeled using Cox proportional hazards models while controlling for demographic and comorbid characteristics. High-volume @entity572 centers were defined as those in the top quartile of arthroplasty volume, while low-volume centers were defined as the bottom quartile. RESULTS: @entity1 undergoing @entity572 for @entity2249 rather than HA were younger (79 vs 83 years, P < .001), more likely to have @entity309 , and less likely to have @entity299 , @entity303 , @entity5 , or @entity6 (all P < .05). Thirty-day mortality after HA was higher (8.4% vs 5.7%; P < .001) as was 1-year mortality (25.9% vs 17.8%; P < .001). After controlling for age, gender, ethnicity, and comorbidities, risk of mortality following @entity572 was 21% lower (hazard ratio [HR] 0.79; P = .003) at 30 days and 22% lower (HR 0.78; P < .001) at 1 year than HA. @entity1 undergoing @entity572 at high-volume arthroplasty centers had improved 1-year mortality when compared to those undergoing @entity572 at low-volume hospitals (HR 0.55; P = .008). CONCLUSIONS: Based on this large, population-based study, there is no basis to assume @entity572 carries a greater mortality risk after @entity173 than does standard HA, even when accounting for institutional volume of hip arthroplasty.
