161 Barriers to Kidney Transplant Waitlisting among Patients with End-Stage Kidney Disease in Puerto Rico

Abstract

OBJECTIVES/GOALS: The prevalence of patients with end-stage kidney disease (ESKD) in PR has increased in the last decade along with an aging population, while waitlisted patients have decreased. Our objective is to compare clinical and sociodemographic characteristics of patients with ESKD on dialysis who are waitlisted from those who are not waitlisted. METHODS/STUDY POPULATION: Retrospective study of all patients with ESKD who received dialysis in PR from 2013-2019, based on the United States Renal Data System data. Variables: (1)waitlisting status (yes or no; waitlisting date); (2)sociodemographics (age at dialysis initiation, sex, zip-code area, health insurance type, and employment status); and (3)clinical characteristics (dialysis initiation date, primary diagnosis of renal disease, comorbidities including obesity, diabetes, peripherovascular/cardiovascular disease, cancer, etc.). Statistics: (1)descriptive statistics (continuous - central tendency [mean, median] and dispersion [standard deviation, interquartile range]; and categorical [frequencies and percentages]); (2)Chi-square test, Students t-test, and Mann Whitney U test to evaluate differences. RESULTS/ANTICIPATED RESULTS: We expect patients on dialysis not waitlisted will be older and have more comorbidities than those who are on dialysis and waitlisted. DISCUSSION/SIGNIFICANCE: Kidney transplant is the choice of therapy for ESKD and its benefits are better quality of life, improved survival, and best long term-cost effectiveness. If our hypothesis is true, findings will highlight the importance of characterizing which patients with ESKD on dialysis are kidney transplant candidates when considering barriers to waitlisting.
