HealthDay News — For adults newly diagnosed with type 2 diabetes mellitus (T2DM), delays to first-line therapy are longest for older patients, those who are Black or of other ethnicities, and those with multimorbidity, according to a study published online in Diabetes, Obesity and Metabolism. Yogini V Chudasama, PhD, from Leicester General Hospital in the United Kingdom, and colleagues examined factors associated with delays in receiving glucose-lowering therapy among 120,409 adults with T2DM initiating first- to fourth-line glucose-lowering therapy in primary care between 2000 and 2018. The researchers found that older patients, those who are Black or of other ethnicities, and those with multimorbidity had the longest delays to prescription of first-line therapy. Compared with those from the least deprived areas, patients from the most deprived areas received earlier first-line treatment. Most patients were treated with metformin, sulphonylureas, dipeptidyl peptidase IV inhibitors, and insulin as first-, second-, third-, and fourth-line prescriptions, respectively (82.4%, 50.4%, 27.7%, and 28.0%, respectively). The median time to prescription was 0.5, 4.1, 4.6, and 4.7 years for first-, second-, third-, and fourth-line glucose-lowering therapy, respectively. Twenty-five percent of patients developed cardiovascular disease and non-cardiovascular disease complications within a median of 12 to 14 years after T2DM diagnosis and received intensification 5 to 6 years later.
