【 摘 要 】

To increase quality of care for critically ill patients admitted to hospitals, understanding various causes of death could provide better quality of care. In this study, medical records of 5360 deceased patientswere reviewed with reference to the mortality reports. A total of 2019 deceased females and 3341 deceased males were studied from 2011 to 2013. Neurologic disorders could be categorized as the highest cause of mortality report (25%). Pulmonary, gastrointestinal and heart diseases could be expressed as 17%, 17% and 15% of death episodes respectively . Stroke caused mortality among neurologic disorders in 35% at the minimum age of 27 and maximum age of 94 years old. To prevent worse outcome in critically ill patients admitted to hospital, quality of care related to neurological, pulmonary, heart and gastrointestinal disorders was suggested to be upgrading. To avoid financial burden to the family of deceased related to population that stayed more than a month in hospital, further study is recommended in advance .
