Evaluation of a community-based intensive multifactorial clinical intervention for type 2 diabetes

Purpose: To examine the effectiveness of a community-based intensive multifactorial clinical intervention for patients with Type 2 diabetes, to evaluate the feasibility of achieving clinical targets for glycemic control in a community setting, and to identify factors that are predictive of glycemic control in this cohort (age, gender, disease duration, continuity of care, pharmacologic treatment, diabetes self-care and smoking status). Methods: Participants with Type 2 diabetes referred to the Diabetes Clinic following dissemination of the 2003 Clinical Practice Guidelines of Canadian Diabetes Association and who attended a minimum of two physician visits within a twelve month period were deemed eligible for participation. 70 patients were included in this retrospective study. Baseline and twelve month values for the following biomedical outcomes were collected via chart audit: BMI, hemoglobin A1c, blood pressure (systolic, diastolic) and lipid profile (HDL, LDL, triglycerides, total cholesterol, TC:HDL ratio). Data for identification of predictive factors for glycemic control were also retrieved by chart audit. Results: The results of the paired t-test yielded a significant improvement in hemoglobin A1c (p<0.05), systolic blood pressure (p<0.01), HDL-cholesterol (p<0.05), LDL-cholesterol (p<0.01), total cholesterol (p<0.05) and total cholesterol:HDL ratio (p<0.05) over twelve months. No significant difference in BMI, diastolic blood pressure or triglycerides was reported over twelve months. Over half the sample (52.9%) achieved clinical targets for glycemic control (hemoglobin A1c <7.0%) at twelve months. Logistic regression analysis identified disease duration (O.R. = 0.90, 95% CI Exp(B) = 0.079 - 0.773, p = 0.01) and continuity of care (O.R. = 0.25, 95% CI Exp(B) = 0.831 - 0.969, p = 0.02) as significant predictors of glycemic control at twelve months. Conclusions: These findings demonstrate the effectiveness of this community-based intensive multifactorial clinical intervention for patients with Type 2 diabetes and show that the implementation of CPGs related to glycemic control is feasible in a community-based setting. Additionally, patients in this cohort with increased disease duration and increased continuity of care were less likely to achieve clinical targets for glycemic control following a twelve month intensive multifactorial clinical intervention for Type 2 diabetes. In summary, health professionals should strive to implement similar intensive multifactorial interventions in community practice in order to decrease the likelihood of diabetes-related complications and improve the patients quality of life.
