I think it should be used aboard ship as a preliminary triage technique. It effectively separates casualties needing physician-guided triage, but it requires frequent repeat triage of the walking wounded for significant injuries previously missed. This is a slightly simplified system that has worked well for me and was used in Vietnam. The items listed under the categories can be easily fitted into the five category NATO system. There is a high likelihood of survival in these severely injured patients.
Urgent intervention is required to prevent death.
Often these casualties represent short operative procedures with a good quality of life if successfully performed. This category of casualties can tolerate delay prior to operative intervention without compromising a successful outcome. Make sure there are no serious underlying injuries to nerves or vessels. Wounds so extensive that, even if they were the only casualty in a stateside trauma hospital, survival would be unlikely. No treatment of complex or time-consuming cases, unless all other operative cases are completed and supplies are not a problem.
