Air medical transport utilization review in North Carolina.

OBJECTIVE: To perform a review of the collective experience of all hospital-based helicopter ambulances in the state of North Carolina for compliance with utilization review criteria. DESIGN: Flight records of the six members of the North Carolina Aeromedical Affiliation for the months of November and December 1989 were compared with utilization review criteria by an independent reviewer. A secondary review was performed by a staff member for each service. Scene responses and patients flown to a hospital other than the sponsor were evaluated. SETTING: All six hospital-based helicopter services in North Carolina. TYPE OF PARTICIPANTS: All available flight records for November and December 1989. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 756 transports, 747 flight records were available for review. Initial review demonstrated compliance with the criteria for 713 (95.4%) patients; secondary review showed compliance for 18 of 34 flights not meeting initial review, for an overall compliance rate of 97.9%. Compliance rates for scene responses and transports taken to a hospital other than the sponsoring facility were 96.6% and 94.1%, respectively. CONCLUSIONS: Review of all flights over a period of two-months by all six hospital-based helicopter services in North Carolina using utilization review criteria demonstrated a very high rate of compliance with the established criteria.
