Abstract

BACKGROUND: Same calendar day discharge (SCDD) following total joint arthroplasty is desirable for patients and surgeons alike. The aim of this study was to compare the success rate of SCDD in an ambulatory surgical center (ASC) versus hospital setting.

METHODS: A retrospective analysis was performed on 510 patients who underwent primary hip and knee total joint arthroplasty over a 2-year period. The final cohort was divided into 2 groups based on location of surgery: ASC (N = 255) or hospital (N = 255). Groups were matched for age, sex, body mass index, American Society of Anesthesiologists score, and Charleston Comorbidity Index. Successes of SCDD, reasons for failure of SCDD, length of stay (LOS), and 90-day readmission and complication rates were recorded.

RESULTS: All SCDD failures were from the hospital setting (36 [65.6%] total knee arthroplasty [TKA] and 19 [34.5%] total hip arthroplasty [THA]). There were no failures from the ASC. The main causes of failed SCDD in both THA and TKA included failed physical therapy and urinary retention. Regarding THA, the ASC group had a significantly shorter total LOS (6.8 [4.4 to 11.6] versus 12.8 [4.7 to 58.0] hours, P < .001). Similarly, TKA patients had a shorter LOS in the ASC (6.9 [4.6 to 12.9] versus 16.9 [6.1 to 57.0], P < .001). Total 90-day readmission rates were higher in the ASC group (2.75% versus 0%), where all but 1 patient underwent TKA. Similarly, complication rates were higher in the ASC group (8.2% versus 2.75%), where all but 1 patient underwent TKA.

CONCLUSION: TJA performed in the ASC, compared to the hospital setting, allowed for reduced LOS and improved success of SCDD.
