Researchers of this study found 10.5% of patients with diabetes who underwent primary lower extremity amputation were readmitted within 30 days, with medical and surgical complications contributing to readmission.

Researchers identified 439 patients with a diagnosis of diabetes who underwent primary lower extremity amputation between 2002 and 2013, and categorized them into groups with and without unplanned readmission within 30 days postoperatively. Comorbidities, hemoglobin A1c level, amputation level and demographic characteristics were determined through chart review.

Results showed 10.5% of patients experienced an unplanned 30-day readmission, with the top reason being readmission for a major surgical event requiring reoperation (37.0%) followed by medical events (28.3%) and minor surgical events (28.3%). According to univariate analysis, readmission was associated with discharge on antibiotics, smoking, chronic kidney disease, peripheral vascular disease and higher Charlson Comorbidity Index. Researchers also found diagnosis of gangrene, discharge on antibiotics, smoking, chronic kidney disease and peripheral vascular disease were independently associated with readmission in multivariate analysis. – by Casey Tingle
