Project Overview

  • Collection of emergency room-based injury data whose purpose is to identify injury mechanisms and risk factors and to produce statistics
  • Establishment and evaluation of injury prevention and management policies using injury data

Survey Target and Implementation System

  • Survey Target: All injury patients who visited the participating hospitals (23) of the In-depth Survey of Emergency Department Injury Patients ※ Patients whose primary and other diagnosis codes fall under S00-T79 (Injury, poisoning, and other specific consequences of external causes) of the International Classification of Diseases
  • Survey Type: Data is collected by dedicated coordinators assigned to each hospital.
  • Number of participating hospitals: 23
  • Survey Method: Use of medical records and implementation of interview surveys

Main Survey Content

  • Consists of a total of 118 questions
  • 60 common items: Demographic characteristics, injury characteristics, treatment outcomes, etc.
  • 58 in-depth items: Composed of 4 in-depth domains
  • Transportation accidents: Accident mechanism at the time of occurrence, medication use, whether protective equipment was worn, etc. (16 items)
  • Head/Spine: Presence of head/spine injury, intervention procedures, severity by injury site (AIS [Abbreviated Injury Scale]), etc. (6 items)
  • Suicide/Poisoning/Falls: Reasons for self-discharge of suicide patients, amount of toxic substance, etc. (13 items)
  • Pediatric/Adolescent injuries: Whether a guardian witnessed the event, type of violence, classification as self-harm/suicide attempt, reasons for poisoning, etc. (23 items)

Data Quality Control and Analysis

  • Implementation of annual surveyor training and quality control meetings (3 times a year)
  • Verification of data fidelity, such as duplicate data and missing required items
  • Analysis of rates of unknown and missing values, reclassification of “other” items, and analysis of the relationship between survey questions

Utilization and Policy Contribution

  • 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
