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

The role of clinical pharmacist in hospital settings of Ethiopia is still new and infant. To evaluate the impact of pharmaceutical care on clinical outcome and medication adherence in type 2 diabetes mellitus (T2DM) patients. 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. 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). These results also suggest the benefits of integrating clinical pharmacist services in multidisciplinary healthcare teams and diabetes management in Ethiopia.
