Patients with insulin-dependent diabetes are at greater risk for perioperative adverse outcomes following total hip arthroplasty

Background: The prevalence of diabetes mellitus (DM) continues to increase among patients undergoing total hip arthroplasty (THA). It is unclear how insulin use is correlated with risk for adverse outcomes. Methods: A cohort of 146,526 patients undergoing primary THA were identified in the 2005-2017 National Surgical Quality Improvement Program database. Patients were classified as insulin-dependent diabetic (IDDM), non-insulin-dependent diabetic (NIDDM), or not diabetic. Multivariate analyses were used. Results: Compared to patients without diabetes, patients with NIDDM were at increased risk for 4 of 17 perioperative adverse outcomes studied. Patients with IDDM were at increased risk for those 4 and 8 additional adverse outcomes (12 of the 17 studied). Conclusion: These findings have important implications for preoperative risk stratification and quality improvement initiatives.

Automated summary

This study found that patients with NIDDM were at increased risk for 4 of 17 perioperative adverse outcomes studied compared to those without diabetes, while patients with IDDM were at increased risk for these 4 outcomes and an additional 8 adverse outcomes. These findings have important implications for preoperative risk stratification and quality improvement initiatives.
