Insulin-Dependent Diabetes Is an Independent Risk Factor for Complications and Readmissions After Total Joint Replacements

This study examined the risk for postoperative complications, reoperations, and readmissions for patients with insulin-dependent diabetes mellitus (IDDM), patients with non-insulin-dependent diabetes mellitus (NIDDM), and patients without diabetes undergoing total joint replacements (TJRs). The American College of Surgeons National Surgical Quality Improvement Program database was queried for all primary TJRs in 2015. The study identified 78,744 TJRs (84.1% nondiabetic patients, 12.0% NIDDM, and 3.9% IDDM). Multiple logistic regression models identified IDDM as an independent risk factor for increased blood loss, myocardial infarctions, pneumonia, renal insufficiency, urinary tract infections, and readmissions when compared with both NIDDM and nondiabetics. Risk for wound complications and reoperations were comparable between all three groups. IDDM increases the risk for medical complications and readmissions after TJRs. Physicians must counsel patients on the increased risks associated with IDDM before elective surgery and provide appropriate medical support for these patients.
