Providing Diabetes Education through Phone Calls Assisted in the Better Control of Hyperglycemia and Improved the Knowledge of Patients on Diabetes Management

Purpose: A recent single-arm pilot study from our group showed a significant decrease in HbA1C in Type-2 diabetes individuals provided with SMS and phone call-based education on glycemic control. Considering the preference of participants to phone call-based education, a randomized control trial (RCT) with parallel design was conducted to determine the impact of phone call-based diabetes educational intervention on the control of hyperglycemia and improvement in the knowledge about diabetes management. Objectives: To determine the impact of phone call-based educational intervention on the control of hyperglycemia and improvement in the knowledge about diabetes management. Methodology: The study was conducted for a period of 12 months on a total of 273 Type-2 diabetic patients (interventional group (n = 135); non-interventional group (n = 138)) who had provided consent to participate. Subjects in the case group received weekly phone calls on diabetes education; whereas the control group received no education. HbA1C investigations were carried out at baseline and at every fourth month until the completion of the study period for the subjects in both the groups. The impact of phone call-based education was measured by comparing HbA1C values as well as by measuring the questionnaire-based knowledge scores on diabetes management. Results: At the end of the study period, there was a significant reduction in HbA1C in 58.8% participants (n = 65) and a manifold (2–5-fold) increase in knowledge on diabetes management among participants in the case group (n = 110). However, no significant difference in HbA1C and knowledge score was observed in participants from the control group (n = 115). Conclusion: Phone call-based diabetes education is a viable option to empower patients for better management of Type-2 diabetes.
