Interventions to support caregivers of older adults undergoing surgery: A systematic review

Introduction: Increasing numbers of caregivers provide support to older adults after surgery, which is associated with stress and negative impacts on their health. Our review questions were: Methods: The databases searched included PubMed, OVID MEDLINE, OVID PsycINFO, EBSCO CINAHL, OVID EMBASE, Web of Science Core Collection, Wiley Cochrane CENTRAL on February 14, 2024. Studies eligible for inclusion were randomized controlled trial (RCT) or quasi-experimental design with control groups, published in English, Dutch, German, French and Persian, included any unpaid caregiver, and the intervention must include a component specifically designed to meet the caregivers' needs. Results: in total 27,845 were screened and 45 full texts were reviewed. Seven RCTs, two pilot RCTS, and four quasi RCTs were included. Only five interventions had any positive impact and included self-management, telehealth, education and a family-centered care model. Conclusion: Few effective interventions were identified and more engagement with caregivers may identify interventions that better target the caregivers' needs.
