Background  Patient education is a cornerstone of treatment in diabetes mellitus, but there is not unanimity of opinion as to how it should be delivered.

Objective  To determine whether a single, intensive group educational program would improve glycosylated hemoglobin (HbA_1c) levels when compared with passive education.

Methods  A total of 106 patients with HbA_1c levels greater than 8.5% were randomized to either an intensive (n = 50) or a passive education (n = 56) group. The intensive education group received 3.5 days of a structured curriculum involving a physician, nurse, nutritionist, pharmacist, exercise physiologist, and a social worker. The passive education group received material sent by mail every 3 months providing basic information on topics related to diabetes management. Patients continued care with their diabetes care provider during the study period. Levels of HbA_1c were measured at baseline and 3, 6, and 12 months after randomization. A matched control group of individuals who declined participation also had HbA_1c levels measured at baseline and 12 months.

Results  Mean ± SD HbA_1c levels fell significantly (P<.001) from baseline (9.9% ± 1.3%) in both the intensive (-2.0%) and passive (-1.9%) education groups at 12 months, and there was no difference between the groups at any evaluation time. Both groups had significantly greater decline (P<.03) in HbA_1c levels than a matched control group (-1.2%) with similar baseline HbA_1c levels that did not receive education.

Conclusions  Patients with elevated HbA_1c levels who were receptive to education had substantial improvement in HbA_1c levels after receiving an educational intervention. In this population, intensive or passive methods of delivering patient education seemed to have similar effect on improving glycemic control.
