Description
Summary:Background Pharmacists’ interventions to improve outcomes of diabetes management have been promising. However, evidence on using telephone-based interventions in pharmacy practice are limited, particularly in developing countries. Objective To evaluate the efficacy of a telephone-based intervention to improve care and clinical outcomes in type-2 diabetes. Setting A referral community pharmacy and drug information center. Method We conducted a two-armed randomized controlled trial on 100 patients with type-2 diabetes. The intervention consisted of 16 telephone calls in 3 month by a trained pharmacist working in an academic drug information center, while the control group received usual care. Before random allocation, patients attended a live education session delivered by pharmacists to learn the basics of diabetes care and to confirm the eligibility criteria. Assessments were performed at baseline, month-3 (after intervention), and month-9 (follow-up). Main outcome measure Hemoglobin A1c (HbA1c). Results Eighty four patient completed the trial. Baseline variables were comparable between the two groups and the baseline value of hemoglobin A1c was 8.00 ± 1.44 in the study population. HbA1c was significantly improved in both groups at month-3 (6.97 ± 1.41 vs. 7.09 ± 1.78) and remained steady at month-9 (6.96 ± 1.44 vs. 7.26 ± 1.85). Lipid profile showed small improvements in the intervention group but was not significant. The adherence score and self-care score improvement was significantly higher in the intervention group at month-3 and were maintained at month-9. Conclusion Medication adherence and self-care significantly improved in the telephone-based intervention group. However, the improvement of clinical outcomes might have been diluted due to the live diabetes education session.
