This study focuses on people with inflammatory bowel disease (Crohn’s disease or ulcerative colitis) who will be undergoing abdominal surgery. The purpose of the study is to compare the short-term surgical outcomes among patients exposed to the Prehabilitation Program compared to those patients not exposed to the Prehabilitation Program. Participants in the Prehabilitation Program will undergo a 4-week preoperative period to complete clinician-led multidisciplinary visits, during which they will be prepared for surgery and recovery through assessments and recommendations focusing on mental health, nutrition, and physical function. Patients who are not in the Prehabilitation Program will not participate in clinician-led multidisciplinary visits; this may be because there is insufficient time prior to surgery to participate in the program or because they choose not to participate. Study procedures will also include questionnaires that assess depression, anxiety, sleep quality and duration, and health-related quality of life. Participants will also be set up with a Garmin activity tracker to determine pre-surgery activity (daily steps).
