There are many ways the severity, or seriousness, of an injury can be measured. Measures that may indicate the severity of an injury are:

  • ED triage categories and waiting times
  • patient’s status at end of ED episode and urgency of hospital admission
  • length of stay in hospital
  • time in intensive care unit (ICU) and receipt of continuous ventilator support (CVS)
  • deaths in hospital
  • numbers and types of injuries and procedures.
