MASCAL: RFID Tracking of Patients, Staff and Equipment to Enhance HospitalResponse to Mass Casualty Events

Most medical facilities practice managing the large numbers of seriously injured patients expected during catastrophic events. During mass casualty events, as the demands on the healthcare team increase, and the challenges faced by managers escalate, workflow bottlenecks begin to develop and system capacity decreases. This paper describes MASCAL, an integrated software-hardware system designed to enhance management of resources at a hospital during a mass casualty situation. MASCAL uses active 802.11b asset tags to track patients, equipment and staff during the response to a disaster. The system integrates tag position information with data from personnel databases, medical information systems, registration applications and the US Navy's TACMEDCS triage application in a custom visual disaster management environment. MASCAL includes interfaces for a hospital command center, local area managers (emergency room, operating suites, radiology, etc.) and registration personnel. MASCAL is an operational system undergoing functional evaluation at the Naval Medical Center, San Diego, CA.
