Abstract
BACKGROUND
Multiple insulin injection therapy can easily be adapted to the patient's needs. Therefore, it is supposed that more intensive insulin therapy is associated with better metabolic control and less hypoglycaemia compared with a conventional insulin strategy in patients with type 2 diabetes.
METHODS
HbA1c and incidence of non-severe and severe hypoglycaemia were analysed with regard to the strategy of insulin therapy [multiple insulin injection therapy with preprandial insulin with or without basal insulin or conventional insulin therapy with twice-daily premix insulin] from 20 943 visits of 1417 people treated with insulin with type 2 diabetes in a university outpatient department for endocrinology and metabolic diseases over a period of 22 years.
RESULTS
Multiple insulin injection therapy was used in 13 896 (66.4%) of all 20 942 visits. Compared with conventional insulin therapy, these patients were younger (62.0 vs 68.7 years; p < 0.001), had a slightly longer diabetes duration (16.5 vs 15.8 years; p < 0.001) and higher body mass index (32.8 vs 30.9 kg/m(2) ; p < 0.001), a higher insulin dose (76.4 vs 46.5 IU/day; p < 0.001), more frequent blood glucose monitorings/week (24.2 vs 14.8; p < 0.001), a slightly lower HbA1c [7.7 (61.2) vs 7.9% (62.9 mmol/mol); p < 0.001] but more non-severe hypoglycaemic incidences per week (0.3 vs 0.2; p = 0.01). Episodes of severe hypoglycaemia were rare and comparable (0.01/patient/year) with both insulin therapy strategies.
CONCLUSIONS
Multiple insulin injection therapy and conventional insulin therapy yielded comparable metabolic control with HbA1c below 8% (63.9 mmol/mol), but multiple insulin injection therapy is associated with higher body mass index and higher incidence of non-severe hypoglycaemia.
