Flowchart of the identification of ‘regular’ adult patients with recorded diabetes and HbA1c control†. †Results are shown as absolute numbers from the data set without adjusting or weighting. ‡At least one consultation per year between 2015 and 2018. §Patients were classified as recorded diabetes when (1) ‘diabetes’ was recorded on two different occasions (as a ‘diagnosis’, ‘reason for encounter’ or ‘reason for prescription’), or (2) antidiabetic medications were prescribed (Anatomical Therapeutic Chemical A10A or A10B; metformin was considered only in the absence of polycystic ovary syndrome diagnosis), or (3) diabetes diagnosis was recorded only once, but there was at least one laboratory result (fasting blood glucose, HbA1c or 2-hour oral glucose tolerance test) above the diabetes threshold. HbA1c, glycated haemoglobin A1c.
