Medicaid status is independently predictive of increased complications, readmission, and mortality following primary total shoulder arthroplasty.

Background: In recent years, several studies have evaluated the effect of Medicaid insurance status on total shoulder arthroplasty (TSA) outcomes and have presented discordant findings. The purpose of this study is to determine if Medicaid status is an independent predictor of all-cause complications, readmission, revision, and mortality following elective primary TSA using a large, national administrative claims database.

Methods: The Nationwide Readmissions Database was queried to identify patients who underwent elective primary TSA from 2016 to 2020.
