National Surgical Quality Improvement Program Analysis of 9110 Reduction Mammaplasty Patients: Identifying Risk Factors Associated With Complications in Patients Older Than 60 Years.

BACKGROUND

The purpose of this study was to identify preoperative risk factors in patients undergoing reduction mammoplasty as well as identify any increased complication risk in patients older than 60 years undergoing reduction mammoplasty.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program data from years 2013-2015 was reviewed. Patients were identified using Current Procedural Terminology code 19318 specific for reduction mammoplasty. Only patients undergoing bilateral procedures were included, and no reconstructive procedures were included. Patient demographics, comorbidities, and 30-day complications were analyzed. Comparative analysis was performed between patients younger than 60 years and patients 60 years and older, identifying risk factors associated with complications in the geriatric population.

RESULTS

A total of 9110 patients undergoing reduction mammoplasty were identified. Of these 1442 (15.83%) were patients older than 60 years. Mean age of all patients was 42 years (range, 18-85 years). Eighty hundred fifty-nine patients were active smokers. Four hundred eighty-two patients were diabetic. Overall, 798 complications occurred with an incidence of 8.7%. Group 1 (<60 years) mean age was 39 years (range, 18-59). Group 2 (>60 years) mean age was 66 years (range, 60-85 years). The geriatric population showed a higher risk of cerebral vascular accidents (P < 0.00006), myocardial infarction (P < 0.02), and readmission (P < 0.03). Smoking was found to be a statistically significant risk factor for superficial surgical site infection, and deep space infection. Diabetes was found to be a statistically significant risk factor for readmission.

CONCLUSIONS

Reduction mammoplasty is a common surgical procedure. It is not uncommon for patients older than 60 years to undergo elective reduction mammoplasty (15.83% incidence), resulting in a cumulative complication rate of 11.65% in the geriatric population compared with 8.89% in the group of patients younger than 60 years. Smoking and diabetes were found to be independent risk factors for complications, regardless of age.
