An Integrative Review of Frailty, Patient Mortality and Graft Failure in Solid Organ Transplant

IntroductionCharacteristics and the impact of frailty on adult solid organ transplant recipients have not been clearly described. The purpose of this integrative review was to identify characteristics of frailty and associations between frailty and patient mortality and graft failure in adult solid organ transplant recipients.MethodsAn integrative literature review was performed using Cooper's integrative methodology. PubMed, Excerpta Medica, and the Cumulative Index of Nursing and Allied Health Literature databases were searched using the terms frailty and transplant. Inclusion criteria were primary research reports, written in English, focusing on adult solid organ transplant recipients, and including graft or patient survival outcomes.ResultsThe review included 35 articles, were largely retrospective, and published between 2015 and 2023 in 11 different countries. Most studies were single-center studies that were not theory-based, and liver transplant recipients were highly represented. Males outnumbered females in the majority of studies and White race was represented in half of the studies. Most studies used one strategy to measure frailty, and modified versions of the Physical Frailty Phenotype were the measurement used most often. Of the 35 articles that investigated the association of frailty with patient mortality, 44 measures were used, and of those, 32 showed a significant association. For graft failure, of the 10 studies included, half showed a significant association between frailty and graft failure.ConclusionThis integrative review offers insights into the characteristics and the association between frailty, patient mortality, and graft failure.
