RESEARCH VISION
Patients undergoing surgery invariably experience a rapid health decline postoperatively, which is followed by a gradual return towards baseline (preoperative) health. Length of postoperative recovery (i.e. the time to return to preoperative health or 鈥榥ormal鈥�) varies depending on patient characteristics, extension of surgery and occurrence of postoperative complications. Prolonged or incomplete postoperative recovery not only increases healthcare costs but is also associated with substantial burden to patients and caregivers (e.g. time away from work, leisure, family and social activities). Several perioperative interventions are proposed to improve recovery for patients, but for these to be adopted, they should increase the value of surgery 鈥� defined as health outcomes achieved relative to the cost of achieving those outcomes.
Our research program focusses on:
Developing and investigating novel and creative interventions to improve postoperative recovery and increase the value of surgery. This includes reorganization of perioperative care into pathways, novel surgical techniques, new pharmacological therapies, pre- and post-operative exercise interventions.
Creating innovative measurement strategies to value the process of postoperative recovery through patient-reported (e.g. self-report questionnaires), clinician-reported (e.g. readiness for hospital discharge) and performance-based (e.g. functional exercise tests) outcomes.
Assessing the economic aspects of surgical recovery, cost-effectiveness of interventions aimed to improve recovery and impact on healthcare and societal costs.
Comparative-effectiveness research and health technology assessment of surgical technologies, in particular those pertaining to MIS and colorectal surgery.
