Knowledge and Associated Factors towards Early Management of Acute Myocardial Infarctions among Nurses Working in the Adult Emergency Department of Selected Public Hospitals in Addis Ababa, Ethiopia

Abstract Background Acute myocardial infarction is a life-threatening condition and the leading cause of death that influences the individual's physical, psychological, and social dimensions. The increasing burden of myocardial infarction remains a low priority for public health in many countries. So, it is essential to determine the nurse’s knowledge of early management of myocardial infarction for life-threatening. Therefore, this study aimed to assess the knowledge and associated factors toward early management of acute myocardial infarction among nurses working in adult emergency rooms at selected public hospitals in Addis Ababa, Ethiopia. 2022 Method An institution-based cross-sectional study design was conducted with 168 nurses working in adult emergency at selected public service hospitals in Addis Ababa, Ethiopia. The data were collected from April 15 to May 15, 2022 by self-administered questionnaire. The data were analyzed by using SPSS version 26 software. Result A total of 168 participants were included in the study, out of which 74(44%) participants had good knowledge of early management of acute myocardial infarction. In multivariable logistic regression analysis showed BSc degree (AOR = 0.06 95%CI (0.007–0.528)), Diploma nurses (AOR = 0.05 95%CI (0.004–0.48)), management guideline of acute myocardial infarction in a unit (AOR = 2.24 95%CI (1.02–4.9)), and training toward early management of acute myocardial infarction (AOR = 4.03 95%CI 1.68–9.69) were the factors significantly associated with the level of ED nurses knowledge towards early management of AMI. Conclusion and Recommendation: This study result indicates participants had inadequate knowledge of early management of acute myocardial infarction among nurses working in an adult emergency. Generally, I recommend that the upgrading education level the program must give for ED nurses, training programs should be provided for ED nurses on early AMI management, and AMI management guidelines/standard tools should be designed to improve ED nurses' knowledge.
