Pharmacist counselling: A new practice for improving out-patient management of diabetes in Sri Lanka

Abstract

INTRODUCTION AND OBJECTIVES: Our study assessed the effectiveness of pharmacist counselling on outpatient management of diabetes. Though this is new to Sri Lanka, many countries include this practice to achieve target treatment outcomes of patients with diabetes.METHODS: 800 participants with diabetes attending outpatient clinics of two Sri Lankan hospitals were assigned either intervention group (IG) or control group (CG). IG received pharmacist counseling for four consecutive monthly visits in addition to standard care. CG received standard care only Glycaemic control was assessed using Glycosylated haemoglobin (HbAlc) post-intervention Adherence and patient-knowledge were assessed using questionnaires at baseline and post-intervention. RESULTS: A Wilcoxon signed-rank test showed that the 4-month intervention made a statistically significant improvement in adherence in the IG. The IG had median adherence score of 5 out of 8 (IQR 6-3 3) at baseline which increased to 7 (IQR 8-6) post-intervention There was no significant change in adherence in the CG.The IG had median HbAlc of7.2% (IQR 1.5%) post-intervention whereas CG had median of7.7% (IQR 1.95%). This difference was statistically significant.The IG had a median score of 36. l 5% (IQR 48% - 24.07%) for the medication related knowledge domain which increased to 65% (IQR 76.4% - 50.4%) post-intervention (P value< 0 001). The CG did not have a significant change in the same at baseline and post-intervention (P = 0 15). CONCLUSION: Pharmacist counselling improved medication adherence, glycaemic control and patients' knowledge. Thus, it can effectively be used for improving the outpatient management of diabetes in Sri Lanka.
