Metabolic control of adults with type 2 diabetes mellitus through education and counseling

Purpose: To test the efficacy of a controlled nursing intervention focused on education and counseling to improve metabolic control of adults diagnosed with diabetes mellitus type 2 in (DMT2) ambulatory care. Design: A quasi-experimental design with repeated measures was selected. A sample of 45 subjects participated, of which 25 were in the experimental group, and 20 in the comparison group. Measures were taken at 0, 3, 6, 9, and 12 months, including glycosylated hemoglobin (HbA1c), psycbosocial, and clinical variables. Findings: Results showed a significant decrease in HbA1c in the experimental group, as well as positive effects of self-care agency, adaptation, and barriers to treatment (plus one interaction) on the HbA1c levels and on the scores of self-care actions. Conclusions: The counseling and educational model applied in the intervention was effective to improve the metabolic control of diabetic patients in the experimental group. Self-care agency, adaptation, and barriers were predictors of self-care measures and level of HbA1c.
