Detection of Patient’s Critical Condition Using Power BI and AI Decision Tree

Unexpected in-hospital cardiac arrest (IHCA) in the emergency department is defined as an unexpected cardiac arrest during the stay in the emergency department with measured vital signs when entering the emergency department, requiring immediate emergency treatment to save a life. Since IHCA is an urgent medical event, especially in the emergency department, this study explored the risk prediction of IHCA events in the emergency department. IHCA not only has a high mortality rate, but is also likely to cause permanent neurological damage. In the emergency environment, due to the complexity and rapid changes in the patient’s condition, traditional assessment tools often fail to identify high-risk cases in a timely manner. In view of this, this study uses both the Power BI visual analysis platform and the binary decision tree model to construct a data-driven risk prediction tool. Power BI analysis successfully presented the dynamic ranking of influencing factors, and the decision tree prediction model showed excellent performance, with an accuracy of 91%, a recall rate of 89%, an F1-score of 89%, and an overall accuracy of 100%; this prediction system is expected to improve the efficiency of emergency medical care, identify high-risk patients in a timely manner, and assist medical staff in intervening in advance and implementing preventive measures. This study provided two different approaches: Power BI and decision tree. Power BI requires no coding and can be used by medical professionals without a programming background, while decision tree is designed for professionals with a programming background. While the structures of Power BI and decision tree differ slightly, they are generally similar and can both serve as intelligent clinical tools.
