BACKGROUND: Total shoulder arthroplasty (TSA) is an increasingly common procedure. This study looked at trends in TSA using a nationwide registry, with a focus on patient demographics, comorbidities, and complications. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent TSA from 2005 to 2018. Cohorts were created based on year of surgery: 2005-2010 (N = 1116), 2011-2014 (N = 5920), and 2015-2018 (N = 16,717). Patient demographics, comorbidities, operative time, hospital length of stay, discharge location, and complications within 30 days of surgery were compared between cohorts using bivariate and multivariate analysis. RESULTS: < .001 for all comparisons) between the 2005-2010 and 2015-2018 cohorts. CONCLUSIONS: Between 2005 and 2018, patients undergoing TSA had increasingly more comorbidities but experienced lower rates of short-term complications, in the context of shorter hospitalizations and more frequent discharge to home.
