Background: The Estimated Post Transplant Survival (EPTS) score is calculated based on age, the presence of diabetes mellitus, years on dialysis, and prior organ transplant. The EPTS score has been validated in other countries.
Objective: To apply and assess the EPTS score in our population of deceased-donor kidney transplants.
Materials and methods: Retrospective study of adult deceased-donor kidney transplants from January, 2003, to December, 2016. For the statistical analysis it was used Spearman’s correlation, receiver-operator curves (ROC) and Kaplan-Meier curves. A p value < 0.05 was considered statistically significant.
Results: 176 adult deceased-donor kidney transplants were included. Medium age was 34.7 ± 11 years; 53.4% were men, 4% diabetics; mean dialysis time was 5.5 ± 3.9 years and 4% had a prior organ transplant. The medium of EPTS score was 16.3 ± 18.7 (1‑94). Spearman’s correlation was −0.394 (p = 0.0001). C value (ROC) was 0.64 ± 0.6 (95% CI, 0.52-0.75) (p = 0.011). Medium survival calculated with Kaplan-Meier in patients with an EPTS score < 20, was 10.2 ± 0.3 years (95% CI, 9.5-10.9) versus patients with EPTS score > 20: 7.03 ± 0.9 years (95% CI, 5.1-8.9) (p = 0.001). Each 20% increase of EPTS, patient survival time diminished (p = 0.0001).
Conclusions: The EPTS score is a useful tool for establishing survival in adult Mexican recipients of deceased-donor kidney transplants.
