Brief Summary

PURPOSE OF THE STUDY?This study aims to assess patients' quality of recovery and satisfaction after metabolic surgery at a tertiary hospital in South Africa using two validated questionnaires. These assess postoperative comfort, return to normal activities, symptoms such as pain, nausea and vomiting, and satisfaction with perioperative care. WHY HAVE PARTICIPANTS BEEN SELECTED? Adults aged 18 years and older undergoing elective metabolic surgery with a protocol-driven anaesthetic will be eligible. A total of 84 participants will be enrolled. WHEN WILL THE RESEARCH BE CONDUCTED? The study will be conducted from September 2025 to September 2026. HOW WILL PARTICIPATION AFFECT TREATMENT? Participation will not alter planned medical, surgical or anaesthetic care. WHAT WILL PARTICIPANTS BE REQUIRED TO DO? Before surgery, the principal investigator or research assistant will explain the study, answer questions and obtain written informed consent. Participants will complete the 15-item Quality of Recovery (QoR-15) questionnaire and the Bauer Patient Satisfaction Questionnaire. The QoR-15 assesses aspects of recovery using scores from 0 (worst) to 10 (best). The Bauer questionnaire assesses postoperative symptoms and satisfaction with care. Both questionnaires will be administered before surgery and repeated on the first postoperative day. WILL PERSONAL INFORMATION BE USED? Participant confidentiality and anonymity will be maintained. Names will appear only on consent forms, which will be securely stored by Dr Tsime in accordance with institutional requirements. Demographic and clinical information will be collected in a de-identified form for research purposes.

Outcome Measures

Primary Outcomes (2)

• To assess patient-reported outcomes using the 15-item Quality of Recovery questionnaire (QoR-15) for patients undergoing metabolic surgery at a tertiary institution.

  The QoR-15 is a validated patient-reported outcomes measure with scores ranging from 0 to 150, where higher scores indicate better postoperative recovery. A score \>122 is considered good recovery.

  Enrolment from pre-operative (baseline) until Day 1 post-operative.

• To assess change in quality of recovery measured using the 15-item Quality of Recovery Questionnaire (QoR-15) for patients undergoing metabolic surgery at a tertiary institution before and after surgery.

  Change in quality recovery will be calculated as the difference between the postoperative Day 1 QoR-15 score and the preoperative baseline QoR-15 score. QoR-15 total scores range from 0 to 150, with higher scores indicating better postoperative recovery. A positive change score indicates an improvement in quality of recovery following surgery.

  From baseline preoperative to postoperative day 1.

Secondary Outcomes (3)

• To assess anaesthesia-related discomfort, using the Bauer questionnaire that is given to patients who undergo metabolic surgery at Dr George Mukhari Academic Hospital.

  Enrolment will be postoperative day 1.

• To assess satisfaction with anaesthesia care after metabolic surgery at a tertiary institution.

  Enrolment will be postoperative day 1.

• To compare quality of recovery with patient satisfaction in patients undergoing metabolic surgery at a tertiary institution.

  Enrolment from postoperative day 1.
