Objective: The aim of this study was to analyze the impact of loosening the erythropoietin payment criteria for peritoneal dialysis patients on their cardiovascular outcomes. Methods: Two cohorts of incident peritoneal dialysis patients were identified according to the time before and after relaxation of the NHI’s erythropoietin payment criteria, designated cohort 1 (n=1759) and cohort 2 (n=2981), respectively. The cohorts were matched according to propensity scores (1754 patients in each cohort) and then followed up for cardiovascular events, which were analyzed with Cox regressions. Results: For the composite cardiovascular endpoint, patients in cohort 2 had a significantly lower risk than those in cohort 1. However, subgroup analysis showed that this risk reduction was observed only in patients with diabetes. Conclusions: After loosening erythropoietin payment criteria, reduced cardiovascular risks were observed, particularly for patients with diabetes. These results indicate that it is crucial to maintain an Hct level above 30% to reduce the cardiovascular risk in patients with diabetes undergoing peritoneal dialysis. %M 33331829 %R 10.2196/18716 %U http://medinform.jmir.org/2020/12/e18716/ %U https://doi.org/10.2196/18716 %U http://www.ncbi.nlm.nih.gov/pubmed/33331829
