title: Risk factors for complications following breast reduction: results from a randomized control trial.
abstract: Reduction mammoplasty has been shown to benefit physical, physiological, and psycho-social health. However, there are some recognized complications. It would be beneficial if one could identify and modify the factors which increase the rate of complications. To determine the effects of resection weight, BMI, age, and smoking on complication rates following reduction mammoplasty. Data were gathered as a part of randomized control trial (RCT) examining psycho-social & QOL benefits of reduction mammoplasty. Sixty-seven consecutive female patients referred to either the Hull Breast Unit or Hull Plastic and Reconstructive Surgery Unit and underwent Inferior pedicle reduction mammoplasty were recruited. Complications were recorded prospectively. Data gathered included resection weight, BMI, age, and smoking status. Smoking status was categorized into current; ex; and never. Prospective records of all complications were noted. SPSS was used for purposes of statistical analysis. Of the 67 patients, 16 (23.9%) had complications. Higher resection weight, increased BMI, and older age are associated with high rate of complications with significance reaching p-values of p < 0.001, p = 0.034, and p = 0.004, respectively. Among the 67 women who had surgery, nine (13.4%) were current smokers, 20 (29.9%) were ex-smokers, and 38 (56.7%) never smoked. The incidence of complications was highest among current smokers and lowest among those who had never smoked. When comparing the current smokers with those who are not currently smoking, there is a 37% difference in the occurrence of complication. The chi-squared test shows that this is a significant difference (p < 0.01) at the 99% confidence interval. Higher resection weight, increased BMI, older age, and smoking are risk factors for complications. Patients should be adequately counseled about losing weight and stopping smoking.
