Adolescents with macromastia face serious physical, emotional, and social burdens because of their large breast size. Studies have shown that reduction mammoplasty results in improvement in physical symptoms and quality of life for these patients. Shared medical appointments (SMAs), defined as individual patient-physician encounters that occur in a group setting, have been successfully applied to clinics for adult patients seeking breast reduction for this condition. We decided to apply the SMA model to our clinic for preoperative evaluation of adolescent patients with macromastia. The purpose of this article is to describe how our clinic implemented SMAs, evaluate changes in clinic efficiency, measure patient quality of life before surgery, and assess patient and provider satisfaction with the SMA model.From February to June 2016, our department instituted SMAs for preoperative evaluation of female adolescent patients with macromastia. We measured days from referral to appointment for 25 patients who attended SMAs and compared this with a retrospective cohort of 21 patients who attended traditional visits from 2013 to 2015.Clinic efficiency was measured in new patients per hour. During SMAs, we also administered the BREAST-Q, Pediatric Quality of Life Inventory, and patient and provider satisfaction surveys. Mean days between referral and office visit was reduced from 75.3 with traditional visits to 40.3 with shared appointments, although this finding was not statistically significant (P = 0.69). New patients per hour increased from 1.33 with traditional visits to 3 with SMAs, without reducing time spent on education or with the surgeon. The mean preoperative BREAST-Q scores were less than 40 for the 4 tested domains, and the mean (SD) total Pediatric Quality of Life Inventory score was 56.7 (14.8). Patients and the provider reported high satisfaction with SMAs, and the provider wishes to continue using SMAs in the clinic.In conclusion, SMAs resulted in high patient and provider satisfaction and increased clinic efficiency, without sacrificing time spent on education or with the surgeon. Low quality-of-life scores demonstrate a need for these patients to be evaluated and treated for their condition. Measuring patient-reported outcomes with validated surveys and improving clinic efficiency without sacrificing patient care have the potential to increase value at our institution.
