An Army corpsman used physician-written triage algorithms to rate the urgency of the chief complaints of 2000 pediatric outpatients. His ratings agreed with subsequent ratings by physicians in 84% of cases. The corpsman assigned a higher care urgency classification in 15% of cases and a lower classification in only 1.2% of cases. No danger to patients resulted from the algorithm-directed screening. Use of a nonprofessional as a triage agent spares the pediatrician, pediatric nurse practitioner and nurse for providing health care. With increasing use of acute care facilities by patients without appointments, physician-written algorithms allow triage agents who lack formal medical training to determine safely the need for care of patients.
