Incidence, worry and discussion about dosing irregularities and self-treated hypoglycaemia amongst HCPs and patients with type 2 diabetes: results from the UK cohort of the Global Attitudes of Patient and Physicians (GAPP2) survey.

AIMS: The Global Attitude of Patients and Physicians 2 (GAPP2) survey sought to address gaps in understanding about real-world basal insulin-taking behaviour and self-treated hypoglycaemia in patients with type 2 diabetes mellitus.
MATERIALS AND METHODS: The Global Attitude of Patients and Physicians 2 was an international, online, cross-sectional study of patients aged at least 40 years with type 2 diabetes taking analogue insulins, and healthcare professionals (HCPs). Patients were recruited from general consumer online research panels, comprising a representative sample of the population to minimise bias. HCPs were recruited from online specialist research panels. The results of the UK cohort are presented here.
RESULTS: The UK cohort constituted 12% of the total GAPP2 population. In this cohort, 15-25% of patients reported that they had reduced, missed or mistimed at least one dose of insulin in the previous month. On the last occasion that patients had reduced a dose, 82% had done so intentionally - most frequently because of concerns about hypoglycaemia. HCP estimates of the numbers of patients with dosing irregularities were nearly fourfold higher than patient reports. More than one-third of HCPs believe their patients under-report the frequency of self-treated hypoglycaemia. Nevertheless, a proportion did not regularly discuss these concerns with their patients.
CONCLUSIONS: Healthcare professionals are in the best position to support patients in making appropriate insulin dose adjustments to help regularise blood glucose levels and reduce treatment-induced hypoglycaemic events. This can be achieved by initiating frequent discussions with all patients and providing education and training when appropriate.
