title: Inpatient mortality after primary total hip arthroplasty: analysis from the National Inpatient Sample database.
abstract: Although inpatient mortality rates following total hip arthroplasty are low, understanding factors that influence inpatient mortality rates is important. Discharge data from the 2007-2008 HCUP Nationwide Inpatient Sample database were used in this study. Patients were identified based on whether they were admitted for a primary total hip arthroplasty and grouped based on their mortality status. All hip and acetabular fracture patients were excluded. Discharge data revealed 508,150 primary total hip arthroplasties with an inpatient mortality rate of 0.13%. The most significant pre-operative predictors of inpatient mortality were increasing age, weekend admission, increased Charlson co-mobidity score, Medicare payer status, race and a Southern hospital region. The two most significant complications post-operatively leading to increased mortality were pulmonary and cardiovascular complications.
