This study compared the outcomes of outpatient revision total shoulder arthroplasty (TSA) to inpatient revision TSA and outpatient primary TSA. The results showed that outpatient revision TSA had higher complication rates, readmission, and reoperation rates compared to outpatient primary TSA. However, there was no increased risk of complications, readmission, or reoperation for outpatient revision TSA compared to inpatient revision TSA.
Background: Total shoulder arthroplasty (TSA) is becoming an increasingly common surgical procedure for numerous shoulder con-ditions. The incidence of revision TSA is increasing because of the increase in primary TSA and the increased utilization of TSA in younger patients. Conducting revision TSA as an outpatient procedure would be beneficial in limiting expenditure and resource allo-cation but must show a similar complication profile compared to inpatient revision TSA in order to justify its clinical value. The purpose of this study is to compare the outcomes of outpatient revision TSA to inpatient revision TSA and outpatient primary TSA. Methods: The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database was queried from 2010-2019 to identify all patients who underwent revision TSA (n = 1456) in either an inpatient or outpatient setting, as well as patients who underwent primary TSA in an outpatient setting (n = 2630). Relevant demographic characteristics were compared between the outpatient revision group and both the inpatient revision and outpatient primary groups. Postoperative complications, readmission, and reoperation rates were also compared between the groups. Results: Patients undergoing inpatient revision TSA exhibited increased rates of preoperative hypertension (P = .013) and had increased prevalence of severe American Society of Anesthesiologists classification (P = .021) compared to patients undergoing outpa-tient revision TSA. Patients undergoing outpatient revision TSA were significantly more likely to experience complications (P < .001), have longer surgical times (P < .001), and undergo readmission (P = .006) and reoperation (P = .049) compared to patients undergoing outpatient primary TSA. There was no significant increase in rates of overall complication, readmission, or reoperation between patients undergoing revision TSA in an outpatient vs. an inpatient setting. Conclusion: Outpatient revision TSA has higher complication rates, readmission, and reoperation rates compared to outpatient primary TSA, similar to previous findings when comparing revision and primary TSA done as an inpatient. However, there was no increased risk of complications, readmission, or reoperation for outpatient revision TSA compared to inpatient revision TSA. Outpatient revision TSA should be considered by orthopedic surgeons in patients who are medically healthy to undergo the procedure as an outpatient surgery.
