Simple triage and rapid treatment
Simple triage and rapid treatment is a triage method used by first responders to quickly classify victims during a mass casualty incident based on the severity of their injury. The method was developed in 1983 by the staff members of Hoag Hospital and Newport Beach Fire Department located in California, and is currently widely used in the United States.
Classification
First responders using START evaluate victims and assign them to one of the following four categories:- Deceased/expectant
- Immediate
- Delayed
- Walking wounded/minor
Responders arriving to the scene of a mass casualty incident may first ask that any victim who is able to walk relocate to a certain area, thereby identifying the ambulatory, or walking wounded, patients. Non-ambulatory patients are then assessed. The only medical intervention used prior to declaring a patient deceased is an attempt to open the airway. Any patient who is not breathing after this attempt is classified as deceased and given a black tag. No further interventions or therapies are attempted on deceased patients until all other patients have been treated. Patients who are breathing and have any of the following conditions are classified as immediate:
- Respiratory rate greater than 30 per minute;
- Radial pulse is absent, or capillary refill is over 2 seconds;
- Unable to follow simple commands
Treatment and evacuation
After all patients have been evaluated, responders use the START classifications to determine priorities for treatment or evacuation to a hospital. The most basic way to use the START classifications is to transport victims in a fixed priority manner: immediate victims, followed by delayed victims, followed by the walking wounded. More detailed secondary triage systems such as SAVE may also be used: in this case, the START classifications are used to determine the order in which victims should undergo secondary triage.START is not a system for determining resource allocation. The classification algorithm used in START does not depend on the number of victims or on the number of resources available to treat them, nor does using START alone provide any prioritization of patients within any of the four triage classes. Therefore, significant differences in implementation of treatment and evacuation may exist across different agencies using START.
