Purpose:Community hospitals performing unicondylar knee arthroplasty (UKA) face increasing financial pressure to transition these procedures to ambulatory surgery centers (ASC). This transition requires an understanding of the time required to safely discharge patients from the facility to comply with limited hours of operation of most ASCs. Therefore, the purpose of this study was to evaluate the average time required for same day discharge (SDD) following unilateral UKA.

Method:This retrospective review included 201 consecutive UKA patients having achieved SDD from a high-volume community hospital. Patient demographics, time of surgical procedure and time of actual discharge from the hospital following surgical closure were recorded. Independent t-tests were performed to compare time to discharge between patients having an incision time prior to and after noon.

Results: The average surgical time was 56.8±8.6 minutes and the average time required for discharge was 259.7 ± 85.2 minutes. Eight patients experienced post-operative nausea, delaying discharge an average of 73.8 minutes (p = 0.016). Procedures starting after noon had significantly shorter time to discharge (185.9 ± 33.7 minutes) compared to those starting prior to noon (263.7 ± 83.1 minutes) (p < 0.001).

Conclusion: On average, discharge required four hours following surgery. Morning surgical volumes and post-operative nausea significantly increased the time required to discharge. Therefore, standard procedures should be evaluated to ensure these barriers can be modified when transitioning to an ambulatory surgical center.
