Print Friendly, PDF & Email


Medical Communications for Combat Casualty Care (MC4) is a ruggedized system-of-systems containing medical software packages fielded to operational medical forces worldwide, providing the tools to digitally record and transfer critical medical data from point of injury to medical treatment facilities worldwide. MC4 relies on software developers such as the Program Executive Office Defense Healthcare Management System (PEO DHMS) to provide global software databases to store data generated by the MC4 system, providing medical situational awareness for operational commanders and patient record visibility to medical staffs worldwide. PEO DHMS currently furnishes Theater Medical Information Program-Joint (TMIP-J) software to MC4 for deployment to operational units.


MC4 systems provide continuity of care from point of injury through roles of care and enable a comprehensive lifelong electronic health record (EHR) for Soldiers resulting in better informed health care providers and easier access to Veterans Affairs medical benefits. MC4 also provides commanders at all levels timely medical situational awareness and unit personnel health status.


TMIP-J applications include:

  • In and out patient
  • Point-of-injury
  • Class VIII (Medical) Logistics
  • Blood Inventory Management
  • Patient Movement and Tracking
  • Medical Surveillance and Situational Awareness
