Institution of same-day total joint replacement at an urban safety net hospital during the COVID-19 pandemic.

BACKGROUND

Increasingly, total hip and total knee replacements are being performed at outpatient ambulatory surgery centers. The purpose of this study was to investigate the feasibility and safety of instituting a same-day surgery program for hip and knee replacement at an urban, safety net hospital.

METHODS

Retrospective review of a prospectively collected registry for all patients scheduled for same-day total joint replacement at a safety net hospital was performed. Medical records were reviewed for patient demographics, same-day hospital admissions, and 30-day emergency room/hospital admissions.

RESULTS

131 same-day total joint replacements were identified, including 76 knees and 55 hips. Median ASA was 3, and median Charlson comorbidity score was 2. Rate of same-day surgery for total joint replacements increased from 4.5% in September 2020 to 100% in September 2021. On major patient outcomes, 3.8% of patients (n = 5) required conversion to inpatient admission. Rate of 30-Day Emergency Department (ED) visits was 13.0% (n = 17). Most common complaints included postoperative pain (n = 10), incision drainage/edema/hematoma (n = 9), and cellulitis (n = 2). 30-Day Hospital Readmissions occurred in 1.5% of patients (n = 2).

CONCLUSION

Same-day hip and knee replacement can be performed safely at a safety net hospital. Unlike dedicated high-volume orthopedic hospitals or outpatient surgery centers, urban safety net hospitals face a different set of challenges and must care for a wide variety of patients who do not plan for their illness and/or may not be able to pay for their care. Outpatient total joint replacement may extend total joint replacement to patients who might not have access otherwise.
