In the Medicare population, researchers found reverse shoulder arthroplasty is performed at a frequency similar to total shoulder arthroplasty but nearly twice as often as shoulder hemiarthroplasty. Additionally, most reverse shoulder arthroplasties are performed by lower-volume surgeons, and the majority of surgeons perform more reverse shoulder arthroplasties than all other anatomic shoulder arthroplasties combined.
Patients 65 years and older from the 100% sample of the 2011 Medicare Part A were analyzed, with the researchers extracting data on demographic characteristics, diagnoses, provider information, reimbursements and lengths of hospital stays from the claims data. The researchers compared reverse shoulder arthroplasty (RSA) with total shoulder arthroplasty (TSA) and shoulder hemiarthroplasty (SHA). For each type of procedure, the researchers analyzed the hospital length-of-stay and hospital payments data from Medicare Part A and compared them with data from the Healthcare Cost and Utilization Project.
