Comprehensive Geriatric Assessment (CGA) and Optimisation Services in Older Kidney Patients: Results from the First UK-Wide Transplant Centre and Renal Unit Survey Study

<b>Background:</b> Demand for renal replacement therapy (including dialysis, transplantation and supportive care) in patients over 60 is increasing. Concerns regarding poorer outcomes and decision-making in this cohort have been raised. Evidence suggests these relate to frailty, multimorbidity and cognitive impairment, all seen frequently in older age. Comprehensive Geriatric Assessment (CGA) is a multidisciplinary methodology proven to improve outcomes relating to this triad and could be transformative for older kidney patients. This national UK survey aims to describe (1) attitudes/beliefs of renal physicians and transplant surgeons in the UK toward the CGA for older potential kidney transplant recipients and those being considered for dialysis or supportive care; (2) provision of CGA services for these patients in the UK; (3) barriers and enablers to the provision of these CGA services in the UK. <b>Methods:</b> The UK's 72 renal units (RUs) and 23 adult kidney transplant centres (TCs) were invited to complete online surveys electronically using a protected link (24 April 2024-31 August 2024). <b>Results:</b> The response rate was 100%. Only six RUs offered CGA services. However, respondents overwhelmingly advocated CGA for older patients being considered for transplant (RUs 47/55, TCs 17/19), dialysis (RUs 52/54) and supportive care (RUs 51/54). Lack of funding to support CGA-OS (45/51), lack of available staff to deliver CGA (44/51) and time constraints (36/51) were reported barriers to implementing CGA by RUs. TCs identified lack of funding (13/18) and published evidence (12/18) as the main barriers. <b>Conclusions</b>: Transplant surgeons and renal physicians alike support CGA for older kidney patients, but only six UK units currently offer the service to these patients. Research developing and implementing CGA for this population is essential to optimise outcomes and influence policy at the national level.
