ABSTRACT
BACKGROUND: This study aims to examine the impact of home-to-transplantation center travel time as a potential barrier to healthcare accessibility. METHODS: Observational study examined adult heart transplant recipients who received a graft between 2012 and 2022 in the United States. Travel time was calculated using the Google Distance Matrix API between the recipient's residence and transplantation center. A multivariable parametric survival model was fitted to minimize confounding bias. RESULTS: Among the 25,923 recipients that met the selection criteria, the median travel time was 51 âmin and 95 â% of recipients lived within a 5-h radius of their center. White recipients experienced longer median travel times (62 âmin, p â< â0.001) compared to Black (36 âmin) or Hispanic (40 âmin) recipients. A travel time of 1-2 âh (survival time ratio [STR] 0.867, p â= â0.035) or >2 âh (STR 0.873, p â= â0.026) away from the transplantation center was independently associated with lower long-term survival rates. CONCLUSION: Extended travel times to transplantation centers may negatively impact long-term survival outcomes for heart transplant recipients, suggesting the need to address this potential barrier to healthcare accessibility.
