To assess the feasibility and acceptability of a multicomponent prehabilitation and perioperative care intervention for older persons with frailty scheduled for elective orthopaedic surgery prior to conducting an RCT. A mixed-methods feasibility study assessed reach, dose, data collection procedure, acceptability and adaptation. Data was collected through patient reported outcomes, electronic medical record, and interviews with patients and healthcare professionals. No pre-defined feasibility criteria were applied. Of those referred for surgery, 30% were screened for frailty, among those eligible, 78% consented to participate. Participants received six of the eight planned phone calls, adherence to nutrition advice and exercise was high, and medication review resulted in at least one drug change for 50% of participants. Qualitative analysis identified key themes including the importance of tailoring care to individual patient needs, strong support from healthcare professionals and family members, and effective interdisciplinary collaboration. The intervention appeared feasible and acceptable to both patients and healthcare professionals. Several adaptations were implemented immediately (refined recruitment procedures, reduced number of health coaching sessions, and modified data collection method), while others were proposed (earlier involvement of geriatrician, focusing on hip and knee surgery, 48-hour follow-up, and improved integration with municipal rehabilitation services and general practitioners). This study demonstrated the feasibility and acceptability of a prehabilitation and perioperative care intervention for older persons with frailty undergoing elective orthopaedic surgery. The proposed adaptations will inform the implementation strategy prior to conducting an RCT to evaluate effects on clinical outcomes and healthcare costs.
