Given the increasing prevalence of hip and knee arthroplasties performed, measures have been implemented to standardize care and effectively improve patient outcomes and decrease costs. Length of stay (LOS) directly affects costs. The purpose of this study was to identify peri-operative and patient related factors that correlated with decreased or increased LOS. A retrospective chart review was conducted of 289 consecutive primary total knee (TKA) and total hip (THA) arthroplasties. Comorbidities indicated by the Charlson Comorbidity Index (CCI), smoking and drinking status, age and BMI were recorded. Intraoperative and post-operative records were reviewed for American Society of Anesthesiologists (ASA) Score, anesthetic type, regional nerve blocks, and blood transfusions. The TKA cohort consisted of 57 males and 86 females, while the THA cohort consisted of 73 males and 73 females.Introduction
