Medical Communications for Combat Casualty Care (2003)

Medical Communications for Combat Casualty Care (MC4) integrates, fields and provides technical support for a comprehensive medical information system enabling comprehensive, lifelong electronic medical records, streamlined logistics and enhanced situational awareness for Army operational commanders.

MC4 is a semi-ruggedized system-of-systems containing medical software packages fielded to operational medical forces worldwide. The MC4 system is comprised of joint software, commercial and government-off-the-shelf products including Theater Medical Information Program-Joint (TMIP-J) applications developed by the Deployment & Readiness Systems (D&RS) Program Management Office of the Defense Health Clinical Systems (DHCS), formerly Defense Health Information Management System (DHIMS).

Deployable medical forces use the MC4 system to gain quick, accurate access to patient histories and forward casualty resuscitation information. The system also provides units with automated tools facilitating patient and item tracking, blood management, medical reporting and medical logistical support. By utilizing this system, relevant medical data flows vertically throughout levels of health care and to joint medical databases.

MC4 was first deployed for a contingency in 2003 to support Operation Iraqi Freedom (OIF) and has since enabled the capture of more than 17 million electronic patient encounters. The Army’s Program Executive Office Enterprise Information Systems (PEO EIS) at Fort Belvoir, Va. oversees the MC4 Product Management Office headquartered at Fort Detrick, Md.
