Introduction
Sodium-glucose co-transporter-2 (SGLT2) inhibitors are oral antihyperglycemic agents for the treatment of people with type 2 diabetes (T2DM). Two recent cardiovascular outcome trials (CVOTs), the EMPA-REG OUTCOME trial and CANVAS Program, have demonstrated that SGLT2 inhibitors have cardiovascular benefit in high-risk cardiovascular patients. The aim of our study will be to identify the prevalence of patients in an English primary care setting with the equivalent cardiovascular risk profile to those included in each of four SGLT2 inhibitor CVOTs: CANVAS, DECLARE, EMPA-REG, and VERTIS CV.
Methods
Routinely collected primary care data from the Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) network database will be used. We will perform a cross-sectional analysis to calculate the prevalence of people that have equivalent cardiovascular risk to participants included in each of the four above-mentioned SGLT2 inhibitor CVOTs. The demographic and clinical characteristics of the subgroups will also be compared with participants in each trial. The study cohort will include people with T2DM in the RCGP RSC dataset. Subgroups of people will be identified using Read codes that most closely match the inclusion criteria of each trial. Descriptive statistics will be used to report the characteristics of people at high cardiovascular risk and compared against those of people in each CVOT.
Planned Outputs
Findings from the study will be submitted for publication in a peer-reviewed journal to report the applicability of each SGLT2 inhibitor trial to real-world clinical practice.
