  "abstract": "Introduction Frailty is a key predictor of adverse surgical outcomes in older adults, contributing to increased postoperative complications, prolonged hospitalisation and delayed recovery. Prehabilitation—targeting improvements in physical function before surgery—can mitigate these risks. However, traditional programmes often face low adherence due to logistical barriers. Integrating smart wearable devices into tele-supervised, home-based prehabilitation may enhance adherence, engagement and clinical outcomes.This trial protocol describes the PREhabilitation of frail elderly PAtients undergoing majoR surgEry at HOME study with the objective to evaluate the effectiveness of a wearable-enhanced, tele-supervised prehabilitation programme (swSEP) versus standard care (unsupervised prehabilitation, uSEP) on improving preoperative functional capacity and postoperative outcomes in frail older adults undergoing major elective surgery.Methods and analysis This single-centre, prospective, randomised controlled trial will enrol 190 patients aged ≥65 years scheduled for major elective, non-cardiac surgery at Singapore General Hospital. Participants with frailty (Edmonton Frail Scale ≥6) will be randomised 1:1 to either the swSEP group (tele-supervised exercise with Fitbit Inspire 3 monitoring) or the uSEP group (standard physiotherapy education, exercise booklet and inspiratory muscle training if maximal inspiratory pressure <100 cm H₂O). The primary outcome is change in 6 min walk test distance from baseline to 1–3 days presurgery. Secondary outcomes include 30 s sit-to-stand test, handgrip strength, postoperative complications (per American College of Surgeons National Surgical Quality Improvement Program), hospital length of stay, readmissions, five-level version of the EuroQol five-dimensional questionnaire (EQ-5D-5L) and adherence. Data will be analysed using t-tests, analysis of covariance, logistic regression and Cox models, with stratification by baseline nutritional status.Ethics and dissemination Approved by the SingHealth Institutional Review Board (CIRB Ref: 2024/2242). Trial registered on ClinicalTrials.gov ( NCT06633614). Results will be disseminated via peer-reviewed publications and academic conferences.
