Poor medication adherence or non-adherence to the prescribed medications among Myocardial Infraction patients is a common problem. This leads to hospital admission due to increased MI exacerbations, reduced physical function, and even death. Previous research indicated that medication adherence is influenced by several issues, including side effects,costs of the medication, dosing frequency and routes of administration. However, research on medication adherence and its associate factors among adult post MI patients in Ethiopia is limited. The objective of this study was to assess Medication adherence and its associated factor among adult post myocardial infarction patients at Tikur Anbessa Specialized and Landmark General Hospitals in Addis Ababa, Ethiopia. An Institutional based cross-sectional study was conducted between February 2021 March 2021. Two hospitals with cardiac centers were selected by lottery method. And proportional Samples were allocated to each hospital.Sample size was calculated using single population proportional formula and the calculated sample size for this study was 422. Data was analyzed using SPSS version 25. Descriptive statistics was used to summarize socio- demographic, characteristics of study participants.Medication adherence was measured by adherence scale interviewer-administered questionnaire. Logistic regression was used to identify factors associated with outcome variables. The result was reported by odds ratio (OR) and Statistical significance was declared at p-value less than 0.05. A total of 401 study participants were recruited with a response rate of 95 %. Adherence rate for MI medication was 57.1%. Age (AOR=4.565; 95%CI(2.3348.933)),income(AOR=1.69395%CI(1.0182.816),sex(AOR=1.863 95%CI(1.045-3.322),havingno complex (AOR= 1.906 95 % CI (1.157-3.141)), and side effect of drug (AOR=3.858 95% CI (2.282-6.523)) were positively associated with medication adherence. cost of medication (92.3%) followed by availability of medications (83.8%) were the main reasonsfor medication non - adherence. Slightly more than half of the respondents are adherent to their medication but majority of the respondents worried about the availability of medications.So, it is recommended that the government should ensure the availability of medications.
