Loss of independence as a metric for racial disparities in lower extremity amputation for diabetes: A National Surgery Quality Improvement Program (NSQIP) analysis

This study assessed the association between race/ethnicity and amputation with mortality and loss of independence (LOI) for diabetic gangrene. We analyzed the American College of Surgeons National Surgery Quality Improvement Program database from 2016 to 2019. Chi-squared tests were performed to evaluate differences in baseline characteristics and complications. Multivariable logistic regression was performed to model LOI and 30-day mortality. 5250 patients with diabetes underwent lower extremity amputation as treatment for gangrene. Hispanic patients were more likely to undergo below the knee amputation (BKA) (P = 0.006). Guillotine amputation (GA) was associated with age > 65 (P
