Hick, J.L., Koenig, K.L., Barbisch, D., and Bey, T.A. (2008). Surge Capacity Concepts for Health Care Facilities: The CO-S-TR Model for Initial Incident Assessment. (Abstract only.) Disaster Medical Public Health Preparedness. 2(Suppl 1): S51-S57.
The CO-S-TR model is designed to be implemented in the immediate aftermath of an incident, and complements the Incident Command System by aiding incident assessment and surge capacity responses at the healthcare facility level. "CO" stands for command, control, communications, and coordination; "S" considers the logistical requirements for staff, stuff, space, and special (event-specific) considerations; "TR" comprises triage, treatment, tracking, and transportation.
