817-P: Inside CKD: Modeling the Direct Economic Burden of Concomitant Chronic Kidney Disease and Type 2 Diabetes

Background: Inside CKD aims to model the future global clinical and economic burden of chronic kidney disease (CKD). Type 2 diabetes (T2D) is a leading cause of CKD, and concomitant CKD and T2D place a significant burden on healthcare systems worldwide. Methods: We used the Inside CKD country-specific, patient-level microsimulation to model global healthcare costs for patients with concomitant CKD and T2D from 2020 to 2025. We constructed virtual populations using country-specific data including demographics, prevalence of CKD (by stage), T2D and complications, and direct costs, from multiple published sources (e.g., NHANES for US; HSE for UK). Results: Preliminary results from three countries show that annual healthcare costs for patients with both CKD and T2D are expected to increase from 2020 to 2025 (US, $51.1B-95.3B; Canada, C$6.5B-11.5B; UK, £2.3B-2.7B) (Figure). Costs attributable to CKD stage 4 are expected to increase the most (US, 4-9% of overall costs; Canada, 9-13%; UK, 7-11%). Conclusion: Healthcare costs for patients with both CKD and T2D are projected to increase in the UK, US and Canada from 2020 to 2025. Later CKD stages are associated with more pronounced cost increases, likely due to both increased prevalence and greater treatment complexity. Early diagnosis and interventions to slow CKD progression are needed to reduce the economic burden of concomitant stage 3-5 CKD and T2D.
