The primary goal of triage is to identify the majority of field trauma victims at risk for life-threatening injuries. When triage criteria are made sufficiently sensitive to accomplish this goal, high rates of overtriage occur. Orange County's original physiologic criteria were associated with an overtriage rate of 18-40% depending on the definition of a major trauma victim. ⋯ Despite this apparent high rate of overtriage, only 5.5% of all paramedic transports were for patients judged to have met field triage criteria. Based on this experience, an approach is suggested for evaluating the balance between over- and undertriage that occurs for a given set of triage criteria. Once this balance has been defined, triage guidelines can be modified to meet regional triage objectives.

The demands made upon the Bristol obstetric flying squad over the past 14 years have been analysed. During this period, the number of calls received per year has decreased dramatically. ⋯ Of importance to anaesthetists is the gross reduction in the number of cases where it is necessary to give anaesthesia 'in the field'. This may lead to complacency and lack of familiarity with the equipment carried by the flying squad.
