Patient reported outcome measures at a large district general hospital post-mastectomy and implant based reconstruction.

11 Background: Breast reconstruction surgery for cancer can be a debilitating and life changing experience for patients, with complex affects on physical and mental health throughout the rehabilitation journey. We conduct a study on a cohort of patients undergoing this procedure, with focus on patient reported outcome measures. Methods: We reviewed all patients who underwent breast reconstruction surgery at our hospital from 2017 to 20223. Demographic, diagnosis, pre- and post-operative adjuvant treatment, and implant characteristics were collected. Psychosocial well being, physical wellbeing, satisfaction with breasts scales of the BREAST-Q were used. Independent t-test was conducted to find differences between PROMs for each group, and linear regression of age and implant size on each score. Results: 69 patients were contacted and 39 PROMS collected. The average age of patients was 57.6 years old. 40% were previous or current smokers and 40.8% had BMI>30. 29 had pre-pectoral placement and 40 sub-pectoral. 17 had smooth implants and 52 textured. The average size of implant was 330mm. Immediate reconstruction was associated with a lower psychosocial score (66.0vs86.9, p=0.02) compared to multi-stage implants. Sub pectoral placement was associated with a higher (75.7vs61.9 p=0.046) psychosocial score than pre pectoral placement. Textured surface was associated with lower physical score than smooth surface (34.7vs50.2 P=0.046). On linear regression, age was positively associated (p=0.007) with psychosocial score. Conclusions: These findings underscore the importance of personalized approaches in surgery, considering implant type, placement technique, and patient age. Surgeons should prioritize patient preferences and needs to optimize post-surgical satisfaction and well-being.
