Abstract

Background: To improve hypoglycaemia management in primary care, more insight is needed into the opportunities to screen for hypoglycaemia risk and subsequent treatment modification using routinely available data. Our primary aim was to assess the number of diabetes patients with an estimated high risk of hypoglycaemia and describe the treatment changes in these patients using pharmacy dispensing data. Additionally, our aim was to investigate patient characteristics associated with such treatment changes. Methods: A drug utilisation cohort study with a 1-year follow-up using the IADB.nl pharmacy database was conducted. Patients aged 35 years or older who received at least two glucose-lowering medication dispensings in 2019 were included. Hypoglycaemia risk was determined using a validated algorithm based on patient demographics and dispensing data. The hypoglycaemia risk score ranged between 0 and 1. The anniversary method was used to evaluate treatment changes after 1 year. Factors associated with treatment changes were assessed by multinomial logistic regression. Results: Around one-quarter (26.9%) of the 36,628 included patients had a hypoglycaemia score of 0.6 or more. After a 1-year follow-up, the majority of these patients (88.9%) experienced no diabetes treatment changes. De-intensification was observed for 8.8% and intensification for 2.3%. Having a high-risk score, being female, and being younger in age were associated with de-intensification. Conclusions: A substantial number of primary care patients using glucose-lowering medications appear at risk of hypoglycaemia, whereas few of them undergo medication de-intensification. Pharmacy dispensing data can be helpful in screening for diabetes patients in whom a review of treatment is indicated.
