  1. Predicting length of stay after hip or knee replacement for rheumatoid arthritis.

    Article - En anglais

    Objective

    To identify predictors of the postoperative length of stay (LOS) after hip or knee replacement for rheumatoid arthritis (RA).

    Methods

    Demographic and clinical characteristics, medications, and postoperative course were abstracted from medical records of patients with RA who underwent total arthroplasties of the knee (TKA) or hip (THA) at our institution between 1987 and 1991.

    The relationship between these variables and the postoperative LOS was examined using life tables, linear regression. and multiple regression analyses.

    Results

    During the 5 years of the study, 137 patients with RA underwent 119 TKA and 105 THA.

    The average LOS was 16.9 ± 8.7 days after THA and 19.5 ± 11.4 days after TKA (p=0.08).

    Significantly longer LOS was associated with age = 55 years, female sex, non-white ethnicity, poor functional status, known positive rheumatoid factor, use of bone cement, and operating room (OR) time longer than 6 hours.

    In a multivariate regression model, a preoperative Steinbrocker functional class 3 or 4 was associated with an increase in LOS of 3.98 days (95% confidence interval 0.78,7.18) and 7.14 days (2.59,11.69), respectively, while a known positive rheumatoid factor predicted an increase in LOS of 2.76 days (0.17,5.35).

    Among operative factors, the use of bone cement was associated with a LOS that was longer by 3.50 days (0.80,6.20), and each hour increase in OR time with a delay in discharge of 1.75 days (1.18,2.33). (...)
