The application of artificial intelligence and machine learning methods in several medical specialties, particularly emergency medicine, is expanding quickly. The use of artificial intelligence in emergency care has been the subject of current research, which has been compiled and evaluated in this study. These investigations fell into three categories: disease prediction and detection, admission, discharge, and mortality need predictions, and machine learning-based triage systems. The most significant studies in each of these categories have been selected, and the algorithms' accuracy and outcomes have been briefly reviewed by citing machine learning methodologies and relevant datasets.
