PREhabilitation of Frail Elderly PAtients Undergoing majoR surgEry at HOME (PREPARE-HOME) Using Smart Wearables

The goal of this clinical trial is to evaluate whether a prehabilitation program using wearable technology can improve physical function and postoperative outcomes in elderly patients (65 years or older) undergoing major elective non-cardiac surgery. The main questions it aims to answer are: Does the prehabilitation program improve physical function, as measured by the 6-minute walk test (6MWT), from baseline to pre-surgery? Does the prehabilitation program reduce postoperative complications and enhance recovery? Researchers will compare participants who receive the prehabilitation program with wearable technology (intervention group) to those receiving standard preoperative care (control group) to see if the intervention results in greater improvements in physical function and postoperative outcomes. Participants will: Follow a personalized exercise program monitored remotely via telemedicine. Wear a Fitbit Aspire 3 device to track vital signs such as heart rate and physical activity. Undergo assessments of physical function and quality of life before surgery.
