Objective: To estimate the economic benefit of replacing non-renal dose adjusted (NRDA) dipeptidyl peptidase-4 (DPP4) inhibitors with renal dose adjusted (RDA) DPP4 inhibitors in patients with impaired kidney function and type 2 diabetes. Patients and Methods: This multicenter study analyzed a total of 67,964,996 prescription records of five teaching hospitals in Korea from January 1, 2012 to December 31, 2018 using a common data model. Prescription patterns of NRDA and RDA DPP4 inhibitors were subgrouped based on estimated glomerular filtration rate (eGFR) determined by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Results: NRDA DPP4 inhibitors were more frequently prescribed to patients with impaired kidney function than those with preserved kidney function (25.7%, 51.3%, 64.3%, and 71.6% in patients with eGFR of ≥60, <60, <45, and <30 mL/min/1.73m(2), respectively). When applying the prescription pattern of DPP4 inhibitors for patients with preserved kidney function to those with impaired kidney function, cost savings per year were 7.6% for eGFR <60 mL/min/1.73m(2) and 30.4% for eGFR <30 mL/min/1.73m(2). Assuming patients with impaired kidney function are solely prescribed with RDA DPP4 inhibitors with appropriate dose reduction, 15.4% to 51.2% per year could be saved depending on kidney impairment severity. Conclusion: NRDA DPP4 inhibitors are frequently prescribed in patients with type 2 diabetes and CKD. Prescribing RDA DPP4 inhibitors with doses adjusted to individual kidney function could alleviate the economic burden associated with medical expenditure. Presentation: Friday, June 16, 2023
