Predictors of Hospital Readmission After Total Shoulder Arthroplasty

The 30-day readmission rate after total shoulder arthroplasty was 2.9%.

• Preoperative predictors of readmission included a classification of 3 or greater by the American Society of Anesthesiologists and a history of cardiac disease.
• Patients with any perioperative complications had a significantly higher readmission risk, with 34% of those affected being readmitted.
• Specific complications, such as periprosthetic joint infection, myocardial infarction, pulmonary embolism, deep venous thrombosis, and pneumonia, were associated with increased readmission rates.
• The majority of readmissions occurred within the first 14 days post-surgery, with 26% occurring by day 5, 32% by day 7, and 55% by day 14.
• Pre-operative medical optimization targeting these complications may help reduce readmission rates.
