The aim of the present study was to identify independent preoperative
hip function characteristics sensitive for preoperative intervention that are
predictive of an extended length of hospital stay (LOS) after primary total hip
arthroplasty (THA).
DESIGN: This is a longitudinal cohort study. A retrospective
chart analysis was conducted on prospectively collected data of patients (158)
who underwent unilateral primary elective cemented THA in a 4-yr period. The main
outcome measure was LOS after primary THA. RESULTS:
The median LOS was 6.0 days.
The authors found an 18.5% increased chance of requiring an LOS of more than 6
days (odds ratio, 2.15; 95% confidence interval, 1.03-4.50) for the patients who
needed to use a walking aid preoperatively and a 23.6% increased chance (odds
ratio, 2.74; 95% confidence interval, 1.31-5.74) for the patients who had
difficulties managing stairs. Sex, age, body mass index, comorbidity, and
preoperative pain did not reach the level of significance in the multivariate analysis. CONCLUSIONS: Patients who are at risk for a longer stay in the hospital
after THA can be identified preoperatively on simple physical function
characteristics. These findings enable the identification of appropriate patients
for preoperative training to improve functional recovery and decrease the LOS after primary THA.
