We obtained standardized data for all patients admitted after a hip fracture between 1994 and 2001. Our primary analytical method was multiple regression analysis. Outcome variables were length of stay, FIM Instrument ratings at discharge and followup, functional gain, and percentage of patients discharged home. The predictor variable was the presence of OA. Covariates were age, sex, race\/ethnicity, other comorbidity, admission FIM ratings, total hip replacement, and time to followup.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We studied 1,953 patients with OA and 11,441 patients without OA admitted to inpatient rehabilitation facilities after hip fracture.
