Identifying Reasons for Failed Same-Day Discharge Following Primary Total Hip Arthroplasty

Background

As total hip arthroplasty (THA) gains popularity in ambulatory surgery centers, it is important to understand the causes of failed same-day discharge (SDD). The purpose of this study is to (1) identify reasons for an overnight stay among patients selected as candidates for SDD following THA and (2) determine what pre-operative factors are more common among patients who fail SDD.

Methods

This is a prospective cohort study of patients undergoing THA who were identified as candidates for SDD (<75 years, ambulate without walker, American Society of Anesthesiologists score 1-3, body mass index <40 kg/m2, and agreed to SDD pre-operatively). The primary outcome was the reason for not discharging home on the same day of surgery. Secondary outcomes included the proportion of patients who failed SDD and any pre-operative patient characteristics that could be linked to failed SDD.

Results

Seventy-eight of 106 (74%) patients pre-selected for SDD were successfully discharged per protocol. Of the 28 (26%) patients who failed SDD, the most common reasons for failure were patient preference (12), dizziness or hypotension (8), failure to clear physical therapy (5), urinary retention (2), and pain management (1). There was a higher percentage of patients in the failed SDD group who reported multiple allergies (P = .02), anxiety/depression (P = .24), obstructive sleep apnea (P = .38), and rheumatoid arthritis (P = .02).

Conclusion

SDD is a viable option for surgeons interested in rapid recovery THA. In a pool of patients selected for SDD, the main cause of SDD failure was a change in patient preference post-operatively, despite having agreed to SDD pre-operatively and meeting all discharge criteria.
