National Trends for Reverse Shoulder Arthroplasty After the Affordable Care Act: An Analysis From 2011 to 2015.
Few studies have investigated nationwide patient trends and health care costs for reverse shoulder arthroplasty (RSA) after 2014. This study uses a large validated nationwide database to retrospectively assess changes in patient and hospital demographic features, hospital costs, and hospital charges for inpatient RSA procedures before and after implementation of the Affordable Care Act. The National Inpatient Sample database was used to identify all patients who underwent RSA between January 2011 and December 2015, yielding 163,171 patients (63.4% female; mean age, 72 years). Categorical data were assessed with chi-square/Fisher's exact test, and continuous data were assessed with analysis of variance. There was an increased proportion of RSA recipients identifying as Hispanic (4.1% to 4.8%) and Native American (0.1% to 0.4%; P<.0001). The proportion of patients who had Medicaid (1.4% to 2.4%) and private insurance (15.1% to 16.6%) increased as well (P<.0001). A decrease in mean hospital costs occurred between 2011 and 2015 (-$256; P=.002), whereas an increase occurred in hospital charges (+$6,314; P<.001). These findings provide insight on RSA use and patient demographic trends in the United States. Additionally, these results help to capture the effects of extended health coverage and new reimbursement models on hospital costs and charges.
