PurposeStructured patient education aiming to improve self-management strategies might be beneficial for insulin-treated diabetic patients. However, in previous studies the extent of the benefit has been inconsistent in different subgroups of patients. The aim of the present study was to assess the potential benefit of a structured inpatient-education program for intensive insulin therapy according to the basal-bolus concept with particular emphasis on self-management strategies.MethodsWe included 81 diabetic patients (59 with type 1, 14 with type 2, eight with other forms) in this retrospective longitudinal study; all had completed the training program on eight consecutive days at a university clinic between 2003 and 2005. Data assessment included HbA1c, LDL-cholesterol, HDL-cholesterol and BMI at baseline (0-15 months before the training) and after 0-5, 5-10 and 10-20 months.ResultsA transient decrease of HbA1c (0.2%, 95% CI: 0.04-0.37, P = 0.017) and LDL-cholesterol levels (9.95 mg/dl, 95% CI: 2.24-17.76, P = 0.013) between baseline and the first follow-up examination was observed in the group overall. Thereafter, HbA1c and LDL-cholesterol were similar to baseline, whereas a persistent increase in HDL-cholesterol (P = 0.025) was evident in the multivariable analysis. No changes in BMI were observed. A significant type-by-time interaction (P = 0.008) in HbA1c suggests a long-term benefit in glycemic control in patients with type 2 diabetes.ConclusionA diabetes training program for intensive insulin therapy with particular emphasis on self-management skills was followed by a moderate and transient improvement of glycemic control and LDL-cholesterol and by a persistent increase in HDL-cholesterol. Long-term improvement in glycemic control was observed only in patients with type 2 diabetes.
