Abstract
Background: -Patients with diabetes often take multiple prescription of medication due to existence of concomitant disease. Medication adherence is associated with improved health outcomes, including decreased health care costs, hospital stay, and mortality. Therefore, the aim of the study was to assess the prevalence and Adherence to multiple prescription of medications and its predictors among Type 2 Diabetic Patients visiting Diabetic Clinic of Addis Ababa tertiary Hospitals, 2019. An institutional based, cross-sectional study conducted on 417 patients with type 2 diabetes mellitus using systematic random sampling. Data were collected by using pre-tested interview based structured questionnaire and checklist guided document review and adherence was assessed using Morisky Medication Adherence Scale-8 (MMAS-8). From total study participants f 233(55.9%) used multiple prescribed medications (concurrent use of multiple clinically indicated medication). Multiple Prescription Medications is significantly associated with raised BMI (AOR: 0.149 CI: 0.056-0.40, p<0.001), increased number of complication (AOR: 0.022 CI: 0.003-0.180) at p-value . 0.05. Of all study participants, 89(38.2%) participants had high adherence, 59(25.3%) medium and 85(36.5%) low adherence to multiple prescribed medication. Young age (AOR: 4.9 CI: 1.82-12.1, p=0.012), short time since diagnosis (AOR: 0.21, CI: 0.05-0.93, p=0.039), positive views about cost of medication (AOR: 7.85, CI: 1.31-47.3, p=0.024), lower number of medications (AOR: 4.73 CI: 1.02, 21.88, p=0.048) and knowing targets of glycemic control (AOR: 6.21 CI: 2.70-14.24, p<0.001 were significantly associated with adherence to multiple prescription of medications at p-value . 0.05. Conclusively, type 2 diabetes mellitus gets complicated in many of the patients with it (as multiple prescribed medications are used to manage the complications) making proportion of multiple prescription higher, and adherence to this multiple prescriptions were continued to be suboptimal. Predictors were identified in the study which could help develop policies for improving adherence in diabetics to change the disease from fatal incurable disease to manageable chronic illness.
