Initiation of biphasic insulin aspart 30/70 in subjects with type 2 diabetes mellitus in a largely primary care-based setting in Sweden

AimsDespite a wealth of clinical trial data supporting use of the premixed insulin analogue, biphasic insulin aspart 30 (BIAsp 30) in the treatment of type 2 diabetes mellitus (T2DM), there is limited documentation of its use in primary care-based clinical practice.MethodsAn observational study investigating the safety and efficacy of BIAsp 30 in routine clinical practice was conducted. Patients were followed up 3 and 6 months after initiating insulin treatment. Safety and efficacy measures were documented.ResultsDuring the course of the study, 1154 patients were included (age range 20–95 years), of whom 89% completed the 6-month follow-up period. Mean HbA1c at baseline was 8.8% (73 mmol/mol), and had improved to 7.2% (55 mmol/mol) after 6 months of treatment. The rate of total hypoglycaemia at completion of the study was 4.1 events per patient year. Major hypoglycaemic events were rare (two in total).ConclusionsBIAsp 30 was initiated safely and effectively in insulin-naïve patients with T2DM. The safety and efficacy profile observed in clinical trials was confirmed in this largely primary care-based setting in Sweden.
