Multiple studies have documented weight loss and metabolic outcomes after bariatric surgery, yet less is known about how these postoperative changes affect patients’ quality of life. The BODY-Q is a well-validated instrument tailored for patient-reported outcome measures (PROMs) in bariatric surgery. Through prospective PROMs collection, we evaluated the impact of bariatric surgery on daily life parameters valued by patients.

Bariatric surgery patients seen at two Boston area hospitals received electronic surveys prior to each appointment from 7/2020-7/2021. Prospectively collected surveys included the BODY-Q physical function scale and the EQ-5D-5L health-related quality of life instrument. Descriptive analyses were performed for patient demographics. Two-sided t-tests were used to compare PROM scores between pre- and postoperative cohorts.

Pre- and postoperative surveys were completed by 458 and 656 patients, respectively. Mean body mass index was 46.0 kg/m2 (SD 11.15) in preoperative patients compared to 35.1 kg/m2 (SD 7.55) in postoperative patients (p<0.01). Patients scored significantly better in overall mean physical function score postoperatively (83.4, SD 21.4 vs 52.2, SD 22.3, p<0.01). Postoperative patients demonstrated a significant improvement in self-reported levels across all dimensions of the EQ-5D (i.e. fewer problems walking, less pain/discomfort). For global health rating, postoperative patients reported significantly better scores than preoperative patients (76.1, SD 20.6 vs 56.0, SD 25.3, p<0.01).

Patients reported significant improvements in physical function and global health scores after bariatric surgery. These PROMs add value to clinical outcomes traditionally followed by surgical clinicians and inform shared decision-making with patients considering bariatric surgery.
