Introduction: A surgical procedure can have repercussions on the functionality and quality of life of patients, reducing their functional capacity by up to 40%; poor preoperative physical performance increases the risk of perioperative morbidity and mortality by 30% and prolongs functional recovery, increasing the hospital stay of the older adult. Prehabilitation is a preoperative intervention that improves the physical, psychological and nutritional condition of the patient to obtain a better postoperative recovery, mobility and functional independence.~Objective: To evaluate changes in functional capacity, postoperative complications and 30-day mortality in patients over 65 years of age undergoing major gastrointestinal surgery who participate in a multimodal prehabilitation program (exercise, nutrition and relaxation).~Methodology: Randomized clinical trial. Two study groups will be compared, an experimental group that will receive the educational intervention (multimodal prehabilitation program) and a control group that will continue with the usual management in the Hospital. The project activities will be carried out in Telehealth modality due to Covid 19 contagion containment measures.~Expected results: To encourage interprofessional work based on common goals with standardization of data and processes to improve physical condition and reduce post-surgical complications; to establish traceability of care, clinical and functional condition of the patient. It is intended to generate scientific evidence, integrate the research groups Méderi, Rehabilitation Sciences and Clinical Research.
Randomized clinical trial evaluating changes in functional capacity, postoperative complications and 30-day mortality in patients over 65 years of age undergoing major gastrointestinal surgery who participate in a multimodal prehabilitation program, compared to non-prehabilitated patients.
