Initiate insulin by aggressive titration and education (INITIATE) -: A randomized study to compare initiation of insulin combination therapy in type 2 diabetic patients individually and in groups

OBJECTIVE - insulin is often postponed for years because initiation is time-consuming. We sought to compare initiation of insulin individually and in groups with respect to change in AlC and several other parameters in type 2 diabetic patients. RESEARCH DESIGN AND METHODS - A randomized (1: 1), multicenter, two-arm, parallel design study with a recruiting period of up to 14 weeks and a 24-week treatment period, Either in groups of 4-8 or individually, using the same personnel and education program, 121 insulin-naive type 2 diabetic patients with an AlC of 7.0-12.0% were randomized to initiate bedtime insulin glargine. The patients visited the treatment center before and at the time of insulin initiation and at 6, 12, and 24 weeks. Patients self-adjusted the insulin dose to achieve a fasting plasma glucose 4.0-5.5 mmol/l. RESULTS - At 24 weeks, mean SE AIC had decreased from 8.7 +/- 0.2 to 6.9 +/- 0.1% in those treated individually and from 8.8 +/- 0.2 to 6.8 +/- 0.1% in those in groups (not significant [NS]). Insulin doses averaged 62 +/- 5 IU and 56 +/- 5 IU at 24 weeks (NS), respectively. The frequency of hypoglycemia was similar. The total time (visits and phone calls) spent in initiating insulin in the patients in groups (2.2 +/- 0.1 h) was 48% less than in those treated individually (4.2 +/- 0.2 h). Diabetes treatment satisfaction improved significantly in both sets of patients. CONCLUSIONS - Similar glycemic control and treatment satisfaction can be achieved by initiating insulin in groups and individually. Starting insulin in groups takes one-half as much time as individual initiation.
