Background:
Previous studies comparing total and reverse shoulder arthroplasty (TSA/RSA) are subject to surgeon selection bias. This study objective is to compare the outcomes and cost of outpatient TSA/RSA to inpatient TSA/RSA.
Methods:
108,889 elective inpatient and outpatient TSA/RSA from Medicare claims data (2016-2018). 90-day readmission and total 90-day costs were compared following propensity score matching.
Results:
Younger and healthier patients are receiving outpatient TSA/RSA. Outpatient TSA/RSA was associated with fewer 90-day readmissions (OR 0.48 CI 0.38-0.59, p < 0.001) and lower 90-day costs (-20.1% CI -19.1%; -21.1%, p < 0.001).
Conclusions:
Outpatient TSA/RSA surgery offers lower complication rates and total costs.
Level Of Evidence:
III.
