BREAST-Q Outcomes before and after Bilateral Reduction Mammaplasty.

BACKGROUND

The BREAST-Q is the only questionnaire specific to bilateral breast reduction that was developed according to federal and international standards. Many payors mandate minimum resection weights for preapproval, despite lacking supportive evidence for this practice. This study aimed to assess changes in BREAST-Q scores after bilateral breast reduction, and determine whether compliance with Schnur requirements impacts improvement in patient-reported outcomes.

METHODS

Patients presenting for bilateral breast reduction from 2011 to 2017 were asked to complete the BREAST-Q preoperatively and postoperatively. Multivariate regression analysis was performed to isolate factors associated with favorable outcomes.

RESULTS

Complete data were available for 238 patients. Mean time to postoperative BREAST-Q was 213 days. Complications occurred in 31 patients (13.0 percent). Mean preoperative BREAST-Q scores were below normative values (p < 0.001), and mean postoperative scores were above normative values (p < 0.001 for Satisfaction with Breasts, Psychosocial Well-being, and Sexual Well-being; and p = 0.05 for Physical Well-being). Postoperative Physical Well-being scores were similar to normative values for resections less than Schnur (p = 0.32), but below norms for resections greater than Schnur (p < 0.0001). On multivariate regression (n = 230), complication and surgeon experience were the only independent predictors of lesser improvement on the Satisfaction with Breasts subscale.

CONCLUSIONS

This study is the largest to include both preoperative and postoperative bilateral breast reduction BREAST-Q scores, and to compare multiple subscales to normative data. Scores overwhelmingly increased, regardless of age or Schnur compliance. Complications negatively impacted degree of BREAST-Q improvement. Interestingly, postoperative Physical Well-being was slightly higher in women with non-Schnur-compliant resections. Bilateral breast reduction substantially improves patient welfare, and our data question the validity of insurer-mandated minimum resections.
