Abstract | OBJECTIVE: METHODS: A single-site, open-label, randomized, 6-month comparative study of 66 patients from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial. Randomization was 1:1 to receive IG or NPH insulin. Data regarding blood glucose control, insulin dosage adjustment and recording of hypoglycemia episodes were obtained through telephone calls; office visits were conducted to measure weight, glycated hemoglobin, fasting plasma glucose and blood glucose profile. The Diabetes Treatment Satisfaction Questionnaire (DTSQ) was used to measure patients' satisfaction with their diabetes treatment. RESULTS: Rates of symptomatic hypoglycemia did not differ significantly between groups: 37.5±2.2 for the IG group and 31.1±2.1 for the NPH group. However, patients treated with NPH insulin had higher frequencies of severe hypoglycemia (6.1±0.9) compared with 2.7±0.6 for the IG group. A significant difference in changes in glycated hemoglobin (A1C) was observed between the groups: the mean ± standard error A1C decreases from baseline were -0.34%±0.11 for the IG group, vs -0.01%±0.10 for the NPH insulin group. The data obtained from the DTSQ showed greater treatment satisfaction in the IG group compared with the NPH insulin group. CONCLUSIONS: Switching from IG to NPH insulin resulted in more than double the rate of severe hypoglycemias and led to decreased metabolic control. Greater treatment satisfaction was observed with IG, compared with NPH insulin, as measured by change from baseline in the DTSQ scores.
