Real-world prevalence of the inclusion criteria for the LEADER trial: Data from a national general practice network

Aims: To explore the prevalence and describe the clinical characteristics of people with type 2 diabetes with a similar cardiovascular (CV) profile to that of the LEADER trial participants in a primary care setting in England. Materials and methods: In this cross-sectional analysis, using the Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) network database, we identified people with type 2 diabetes meeting the LEADER inclusion criteria. We identified people's CV risk factors using computerized medical records. Additionally, we assessed the prescription pattern of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in this cohort. Results: Of 1 275 461 adults, we identified 84 394 with type 2 diabetes, of whom 14 000 (16.6%) met the LEADER inclusion criteria for established or high-risk CV disease (RCGP RSC-CVD group). The LEADER cohort was younger than the RCGP RSC-CVD group (64.2 vs 73.2 years), had higher mean glycated haemoglobin (71.6 vs 67.1 mmol/mol) and blood pressure (BP) values (systolic BP: 135.9 vs 132.9 mmHg; diastolic BP: 77.2 vs 72.7 mmHg), and a higher mean body mass index (32.5 vs 30.9 kg/m2). In the RCGP RSC-CVD group, only 1215 people (8.7%) had ever been prescribed a GLP-1RA and 760 (5.4%) had ever received liraglutide. Conclusions: In a cohort of English general practice patients, one in six people with type 2 diabetes met the LEADER inclusion criteria, and less than one in 10 of these received liraglutide, a drug which has demonstrated CV benefits amongst others. There is scope to improve the outlook in people with type 2 diabetes and high CV risk through evidence-based use of specific GLP-1RAs.
