A preliminary study to evaluate the impact of pharmaceutical care services on clinical outcome and medication adherence in type 2 diabetes mellitus patients from Ethiopian perspective

Abstract

Background: The role of clinical pharmacist in hospital settings of Ethiopia is still new and infant. Objective: To evaluate the impact of pharmaceutical care on clinical outcome and medication adherence in type 2 diabetes mellitus (T2DM) patients. Methods: A single cantered, pre-post interventional study design was carried out by enrolling 100 uncontrolled T2DM patients from March 1-August 30, 2020. The intervention package included assessment of pharmacological and non-pharmacological needs, counselling patients in person at the clinic, and providing educational materials. Results: Of the 100 patients initially enrolled, 87(87%) completed the follow-up and included in the final data analysis. The intervention showed a decrease in average FBG, systolic blood pressure (SBP), low density lipoprotein cholesterol (LDL-C) by 47.3 mg/dL, 22.6mmHg and 31.4mg/dL, while high density lipoprotein cholesterol (HDL-C) and estimated glomerular filtration rate (eGFR) exhibited significant increase by 13.4 mg/dL and 11.5 ml/min/1.73m2 respectively (p<0.0001). In addition, diastolic blood pressure, lipid values, kidney function parameters, and liver function parameters showed significant decrease in post intervention compared to pre-intervention (p<0.05). Medication adherence of the patients increased significantly at 6-month follow-up (p<0.001). Conclusion: These results also suggest the benefits of integrating clinical pharmacist services in multidisciplinary healthcare teams and diabetes management in Ethiopia.
