The mortality rate is still very high in most ICUs especially in the developing countries due to late presentation of patients, unavailability of welltrained staff and lack of life support equipment. This study tried to identify the causes and circumstances of the death of critically ill patients. Objectives : To identify causes and circumstance of deaths of patients admitted to the adult intensive care unit (ICU) at Tirunesh Beijing Hospital public hospital, Addis Ababa, 2021. Methods: A retrospective cross-sectional study was conducted. All patient charts who were admitted and died in adult ICU from Sept 2018 to August 2020 and met the criteria were included. Data was collected by using structured and pretested checklists. SPSS version 25 software was used for data entry and analysis. Result: A total of 193 death cards were reviewed, of which 116(60.1%) were males and 77(39.9%) were females. Common deaths 91(47.2%) occurred in the age group20-40yrs with meanstandard deviation of 43.92±17.26 years. Stroke is the leading cause of death accounting for 27(14%) of total death followed by Retroviral infection (13.5%).The mortality of patients admitted in MICU was 39% and 52.8% of the deaths took place in the first 72 hours of admission to theintensive care unit. Conclusion: The total mortality was considerably high and it is affecting the young age groups. Majority of the patients are dying in the first 72 hours, indicating that most patients are visiting the intensive care unit in the late stages of their illnesses.
