• Securing real-time injury surveillance data, including the status of injury patient occurrence in the emergency room and major causes
• Supporting the establishment of prevention policies by analyzing the characteristics of emergency room visits by age and injury type
• Utilizing data for early identification of high-risk injury groups and prevention strategies
• Providing data for community injury prevention projects and the improvement of laws and infrastructure
