Abstract

We conducted a randomized controlled trial to evaluate patients undergoing a total hip arthroplasty (THA) who were discharged from the hospital either on the day of surgery (outpatient) or were admitted overnight following surgery (inpatient). Our primary outcome was the rate of serious adverse events during the first three months postoperatively. Secondary outcome measures included cost, patient satisfaction, functional outcomes, quality of life and pain. We found no statistically significant difference between the two groups in serious adverse events. We found that outpatient THA was less expensive from the perspectives of the hospital and ministry of health; but the difference in cost was balanced by a relatively equivalent increase in indirect expenditures paid by society. No other statistically significant differences were found between groups. Based on the results from this preliminary analysis of a larger ongoing study, outpatient THA is safe and can contribute to significant cost savings.
