Defining the Association between Diabetes and Plastic Surgery Outcomes: An Analysis of Nearly 40,000 Patients

Abstract

Background: Diabetes is an increasingly prevalent comorbidity in patients presenting for surgery, impacting nearly 14% of adults in the United States. Although it is known that diabetic patients are at an increased risk for postoperative complications, there is a paucity of literature on the specific ramifications of diabetes on different surgical procedures.

Methods: Using the American College of Surgeons National Surgical Quality Improvement Program dataset, demographics, outcomes, and length of in-patient hospitalization were examined for patients who underwent plastic surgery between 2007 and 2012. Adjusted multivariable logistic regression models were used to assess the relationship between diabetes status and a spectrum of medical and surgical postoperative outcomes.

Results: Thirty-nine thousand four hundred seventy-five plastic surgery patients were identified, including 1,222 (3.10%) with insulin-dependent diabetes mellitus (IDDM) and 1,915 (4.75%) with non-insulin-dependent diabetes mellitus (NIDDM), who had undergone breast, hand/upper and lower extremity, abdominal, or craniofacial procedures. Logistic regression analyses showed that only insulin-dependent diabetics had a higher likelihood of surgical complications (IDDM: P value < 0.0001; NIDDM: P value < 0.103), whereas patients with both IDDM and NIDDM had increased likelihoods of medical complications (IDDM: P value < 0.001; NIDDM: P value = 0.0093) compared with nondiabetics. Average hospital stay for diabetics was also longer than for nondiabetics.

Conclusions: Diabetes is associated with an increase in a multitude of postoperative complications and in hospital length of stay, in patients undergoing plastic surgery. Diabetes status should thus be evaluated and addressed when counseling patients preoperatively. Risks may be further stratified based on IDDM versus NIDDM status.
