Hypoglycemia is the most frequent acute complication mainly in diabetics treated by insulin or sulphonylurea derivatives.
HAT (Hypoglycaemia Assessment Tool) study was international, non-interventional study, which investigated the
incidence of hypoglycaemia in ’real-world’ of diabetes patients. Primary objective was to determine the percentage of
patients experiencing at least one hypoglycaemic event during the observational period among insulin-treated patients
with type 1 and type 2 diabetes mellitus. In Slovakia, study was done in 51 centres and 510 patients participated
in study. Any hypoglycaemia was present in 92, 1 % type 1 diabetic patients and in 56 % type 2 diabetic patients. Severe
hypoglycaemia (requested assistance of another person) was not rare (20,9% type 1 diabetes and 8,4 % type 2 diabetes).
HAT study confirmed, that fear of hypoglycaemia is frequent in type 1 and also in type 2 diabetic patients and
it influences adherence to treatment.
