Effect of Medical Accessibility on Long-Term Survival in Liver Transplantation

초록

Background: Medical accessibility is important in liver transplantation (LT) because of the risk of infections associated with the use of immunosuppressants and complications that require continuous treatment, such as biliary stenosis. However, the effect of medical accessibility on LT success rates has yet to be scrutinized. The aim of this retrospective observational study is to determine whether medical accessibility affects LT outcomes. Material/Methods: We enrolled patients who had undergone LT at Samsung Medical Center between January 2017 and December 2021. The level of medical access was divided into 2 categories (difficult and easy) based on a cutoff of a 120-min commute on public transportation to access LT. Baseline characteristics were calibrated with propensity score matching. The outcomes (overall survival and graft survival) and severity of emergency center visits according to medical accessibility were also investigated. Results: A total of 486 patients was included in this study. The median time to reach the hospital by public transportation was 135 min. Sex, Child-Pugh classification, Model for End-stage Liver Disease score, presence of hepatocellular carcinoma, and donor type were calibrated with propensity score matching, and each group consisted of 186 patients. The overall survival (88.3% vs 86.2%, P=0.67, 5-year) and graft survival (98.6% vs 95.4%, P=0.086, 5-year) showed no significant differences between the difficult-to-access and easy-to-access groups. While severity of emergency center visits differed between the difficult group (27.6%) and the easy group (15.5%), the difference was not statistically significant. Conclusions: Medical access to LT did tend to increase emergency center presentation severity but did not affect long-term outcomes.
