In a study published in the Journal of Diabetes, Obesity and Metabolism, a team ofacademics from Cardiff University and the University of Bristol reviewed Clinical Practice Research Data (CPRD) to estimate the prevalence of insulin use in the UK population.

"Understanding the pattern of insulin use is limited by a lack of data characterizing the prevalence of insulin use in the UK," according to Craig Currie, Professor of Applied Pharmacoepidemiology at Cardiff University's School of Medicine, who led the study alongside colleagues from the University of Bristol.
