Abstract
Abstract Background Due to the multiple comorbidities and the associated complications among advanced CKD population, assessing potentially inappropriate medications (PIM) in these patients is an important task for physicians and multidisciplinary care team members. This study aimed to investigate the impact of the national pre-ESRD pay-for-performance (P4P) program on prescribing quality in Taiwan. Methods We conducted a retrospective cohort study using data from National Health Insurance Research Database (NHIRD) maintained by the Health and Welfare Data Science Center, Ministry of Health and Welfare (HWDC, MOHW). The incidents of CKD in year 2010 were observed until the end of 2017. Adult patients who initiated maintenance dialysis therapy were enrolled. To identify the use of PIM that should be avoided in advanced CKD patients, the Beers 2019 criteria and latest Taiwan Manual of Renal Injury Prevention and Drug Safety were applied. We measured PIM use in one year before starting long-term dialysis. Results Among 7,828 participants underwent continuous dialysis treatment, 2,119 (27.1%) were P4P patients. Most (90.4%) participants were prescribed one or more PIMs before ESRD initiation. After adjusted age, sex, Charlson Comorbidity Index (CCI) and the number of nephrologist visits, the logistic regression showed lower probability of PIM use in the P4P enrollees (OR = 0.56, 95% CI = 0.47-0.66). The effect of P4P on PIM was more prominent in the subgroups of patients who were female and CCI≤3. Conclusions The implementation of the pre-ESRD P4P program might reduce PIM use among CKD patients. Our results underline the strategy of financial incentives in the payment design to improve prescribing patterns. Key messages Prescribing potentially inappropriate medications is common among patients who were approaching ESRD. The study highlights the importance of implementing the pre-ESRD P4P program to reduce PIM use in advanced CKD patients.
