BackgroundThe National Health Insurance Administration in Taiwan initiated a nationwide pre-end-stage renal disease (ESRD) pay-for-performance (P4P) programme at the end of 2006 to improve quality of care for chronic kidney disease (CKD) patients. This study aimed to examine this programme's effect on patients' clinical outcomes and its cost-effectiveness among advanced CKD patients.MethodsWe conducted a longitudinal observational matched cohort study using two nationwide population-based datasets. The major outcomes of interests were incidence of dialysis, all-cause mortality, direct medical costs, life years (LYs) and incremental cost-effectiveness ratio comparing matched P4P and non-P4P advanced CKD patients. Competing-risk analysis, general linear regression and bootstrapping statistical methods were used for the analysis.ResultsSubdistribution hazard ratio (95% confidence intervals) for advanced CKD patients enrolled in the P4P programme, compared with those who did not enrol, were 0.845 (0.779-0.916) for incidence of dialysis and 0.792 (0.673-0.932) for all-cause mortality. LYs for P4P and non-P4P patients who initiated dialysis were 2.83 and 2.74, respectively. The adjusted incremental CKD-related costs and other-cause-related costs were NT$114 704 (US$3823) and NT$32 420 (US$1080) for P4P and non-P4P patients who initiated dialysis, respectively, and NT$-3434 (US$114) and NT$45 836 (US$1572) for P4P and non-P4P patients who did not initiate dialysis, respectively, during the 3-year follow-up period.ConclusionsP4P patients had lower risks of both incidence of dialysis initiation and death. In addition, our empirical findings suggest that the P4P pre-ESRD programme in Taiwan provided a long-term cost-effective use of resources and cost savings for advanced CKD patients.© The Author 2016.
