- Abstract
Aims: To investigate how the cardiovascular (CV) risk benefits of dapagliflozin translate into healthcare costs compared with other non‐sodium–glucose cotransporter‐2 inhibitor glucose‐lowering drugs (oGLDs) in a real‐world population with type 2 diabetes (T2D) that is similar to the population of the DECLARE‐TIMI 58 trial. Methods: Patients initiating dapagliflozin or oGLDs between 2013 and 2016 in Swedish nationwide healthcare registries were included if they fulfilled inclusion and exclusion criteria of the DECLARE‐TIMI 58 trial (DECLARE‐like population). Propensity scores for the likelihood of dapagliflozin initiation were calculated, followed by 1:3 matching with initiators of oGLDs. Per‐patient cumulative costs for hospital healthcare (in‐ and outpatient) and for drugs were calculated from new initiation until end of follow‐up. Results: A total of 24 828 patients initiated a new GLD; 6207 initiated dapagliflozin and 18 621 initiated an oGLD. After matching based on 96 clinical and healthcare cost variables, groups were balanced at baseline. Mean cumulative 30‐month healthcare cost per patient was similar in the dapagliflozin and oGLD groups ($11 807 and $11 906, respectively; difference, −$99; 95% CI, −$629, $483; P = 0.644). Initiation of dapagliflozin rather than an oGLD was associated with significantly lower hospital costs (−$658; 95% CI, −$1169, −$108; P = 0.024) and significantly higher drug costs ($559; 95% CI, $471, $648; P < 0.001). Hospital cost difference was related mainly to fewer CV‐ and T2D‐associated complications with use of dapagliflozin compared with use of an oGLD (−$363; 95% CI, −$665, −$61; P = 0.008). Conclusion: In a nationwide, real‐world, DECLARE‐like population, dapagliflozin was associated with lower hospital costs compared with an oGLD, mainly as a result of reduced rates of CV‐ and T2D‐associated complications.
