Evaluation of Diabetes Mellitus as a Risk Factor for Major Complications in Patients Undergoing Aesthetic Surgery.

Abstract

Diabetes mellitus has been linked with a variety of perioperative adverse events across surgical disciplines. There is a paucity of studies systematically examining risk factors, including diabetes, and complications of aesthetic surgical procedures. The purpose of this study was to compare incidence and type of complications between diabetic and non-diabetic patients undergoing various aesthetic surgical procedures, to identify specific procedures where diabetes significantly increases risk of complications, and to study diabetes as an independent risk factor for major complications following aesthetic surgery. A prospective cohort of 129,007 patients who enrolled into the CosmetAssure insurance program and underwent cosmetic surgical procedures between May 2008 and May 2013 were reviewed. Diabetes was evaluated as risk factor for major complications, requiring hospital admission, emergency room visit, or a reoperation within 30 days after surgery. Multivariate regression analysis was performed controlling for the effects of age, smoking, obesity, gender, type of procedures, and surgical facility. Overall, 2506 patients (1.9%) had a major complication. Diabetics had significantly more complications compared to non-diabetics (3.1% vs 1.9%, P < 0.01). In univariate analysis, infectious (1.1% vs 0.5%, P < 0.01) and pulmonary (0.3% vs 0.1%, P < 0.01) complications were significantly higher among diabetics. Notably, diabetics had higher risks of complication in body cases (4.3% vs 2.6%, P < 0.01) and specifically abdominoplasty (6.1% vs 3.0%, P < 0.01). In multivariate analysis, diabetes was found to be an independent risk factor of any complication (relative risk 1.31, P = 0.03) and infection (relative risk 1.70, P < 0.01). Diabetes is an independent risk factor of major complications, particularly infection, after aesthetic surgical procedures.
