Frailty, a measure of physiologic reserve, increases the risk of delayed graft function, longer length of stay, early hospital readmission, immunosuppression intolerance, and mortality among kidney transplant (KT) recipients. Despite its clinical importance in predicting KT outcomes, there are no national estimates of the prevalence or geographic distribution of frailty among US KT recipients.
METHODS: Frailty (Fried phenotype) was prospectively measured in 1,065 KT recipients (12/2008-12/2016) in our multi-center cohort. Using SRTR data on 126,376 KT recipients, we projected the prevalence of frailty and intermediate frailty using predictive mean matching to multiply impute frailty scores, accounting for recipient, donor, transplant, and post-transplant factors.
RESULTS: In our multi-center cohort, the prevalence of frailty and intermediate frailty were 18.4% and 30.0%, respectively, among deceased-donor KT (DDKT) recipients and 14.5% and 28.1%, respectively, among living-donor KT (LDKT) recipients. Projected nationally, the prevalence of frailty and intermediate frailty were 18.0% (95% CI: 14.7-21.3%) and 29.9% (95% CI: 27.5-32.2%), respectively, among DDKT recipients and 12.5% (95% CI: 10.8-14.3%) and 28.4% (95% CI: 23.8-33.0%), respectively, among LDKT recipients. Frailty prevalence varied by geography (p<0.001) (Figures 1 and 2).
CONCLUSION: We project that nearly 20% of KTs 2000-2016 were performed with frail recipients; however, these recipients and their providers were likely not aware of their higher risk for adverse post-KT outcomes. Given its prevalence, transplant programs should consider assessing frailty during KT evaluation to improve informed consent and identify candidates for pre-KT interventions.
