The need for standardized perioperative care for patients undergoing bariatric and metabolic surgery in the United Kingdom

Summary Enhanced recovery after surgery (ERAS) protocols are shown to improve patient outcomes and reduce length of hospital stay. However, there is currently limited consensus on the perioperative management of patients undergoing bariatric and metabolic surgery (BMS) in the United Kingdom. This study aims to survey the level of consistency in patient care undergoing BMS. Bariatric nurse specialists from 30 bariatric units completed an anonymised, online survey from 21 December 2022 to 21 February 2023. Most units (77%) have implemented a premade postoperative care bundle protocol including predetermined timing of oral intake (77%) and postoperative day 1 bloods (60%). 63% of units have also established pre‐set analgesia and anti‐emetic bundles. Date of discharge is variable, ranging from 1 day after surgery (50%) to a ‘two night stay’ protocol (33%) to within 4 days after surgery (17%). Most follow‐up clinics are either led by dietitians (33%) or both bariatric nurse specialists and dietitians collaboratively (57%). Patients are usually established on solid food 6 weeks after surgery in 53% (16/30) units. Chemical venous thromboembolism (VTE) prophylaxis was either given on day of surgery postoperatively (60%), day before (20%) or after (17%) surgery. Our study shows significant variability of care throughout the surgical pathway, in the study population. The results suggest a need for consensus guidelines outlining the best‐practice approach to managing patients undergoing BMS; due to the heterogeneity of the patient group, these guidelines should contain overarching generalisable recommendations that can then be tailored to individual patients.
