Cost-effectiveness of dapagliflozin plus standard treatment compared to standard therapy for the management of chronic kidney disease in Colombia.

ABSTRACT

BACKGROUND: The DAPA-CKD study showed that dapagliflozin added to standard treatment reduced the risk of chronic kidney disease progression, and death from renal or cardiovascular causes compared to placebo. OBJECTIVE: Assess the cost-effectiveness of dapagliflozin and standard treatment versus standard treatment alone for chronic kidney disease within the Colombian health system. METHODS: We employed a Markov model based on the DAPA-CKD study, tailored to the Colombian scenario. The model forecasted hospitalizations for heart failure, overall and cardiovascular mortality, and chronic kidney disease progression over a 10-year horizon with a 5% discount rate. RESULTS: Dapagliflozin combined with standard treatment is a cost-effective intervention in treating stage 2-4 CKD. In the base case, the ICER was US $5,366, below 1 GDP (US $6.558) per capita. This was consistent in the sensitivity analyses. CONCLUSION: Our study showed that dapagliflozin, when combined with standard treatment, is cost-effective against standard treatment alone, aligning with Colombia's willingness-to-pay threshold.
