Effects of a Labor Dispute on a Hospital-Based Helicopter Air Ambulance Service's Volume and Destinations.

Objective: In the United States, there are few unionized hospitals with air medical transport agencies. When labor disputes and strikes occur, information about the effect on helicopter air ambulances and critical care ground transport services is limited. For this study, a helicopter air ambulance and critical care ground transport agency's volume of transports was examined before, during, and after a strike and compared with volumes from the prior year.
