Three and Twelve-Month Analysis of the PROM-Q Study: Comparison of Patient-Reported Outcome Measures Using the BREAST-Q Questionnaire in Pre- Vs. Sub-Pectoral Implant-Based Immediate Breast Reconstruction

Implant-based breast reconstruction (IBR) is being increasingly performed with implant placed above the pectoral muscle (pre-pectoral), instead of below the pectoral muscle (sub-pectoral). Currently, there is a lack of comparative data on clinical and patient-perceived outcomes between pre- vs. sub-pectoral IBR. We investigated whether this difference in surgical approach influenced clinical or patient-perceived outcomes. This prospective non-randomised longitudinal cohort study (ClinicalTrials.gov identifier: NCT04842240) recruited patients undergoing immediate IBR at the Leeds Breast Unit (Sep 2019–Sep 2021). Data collection included patient characteristics and post-operative complications. Patient-Reported Outcome Measures were collected using the BREAST-Q questionnaire at baseline, 2 weeks, 3- and 12-months post-surgery. Seventy-eight patients underwent IBR (46 patients pre-pectoral; 59
