To fight and win in tomorrow’s battlespace, U.S. commanders, medical and logistics planners, and warfighters require a system that provides accurate and reliable real-time or near real-time information regarding personnel, supplies, and equipment on a collaborative platform. Through the Medical Common Operating Picture (MedCOP), Joint Operational Medicine Information Systems, under the Program Executive Office for Defense Healthcare Management Systems, provides this. This poster describes JOMIS’ development of MedCOP as the joint health services’ interactive decision support platform that arms command surgeons and medical commanders with near real-time health surveillance and medical operations visibility to enable well-informed decisions in a changing operational landscape. Large-scale combat operations will differ substantially from counterinsurgency and low-intensity operations of the last 20 years. The U.S. military can no longer rely on air dominance, large fixed in-theater operating/logistics bases, or stable and secure ground/air lines-of-communication to be the norm. The U.S. and unified action partners will face adversaries capable of anti-access/area-denial operations; employment of multi-domain combat platforms and assets; and precision long-range (likely hyper-sonic) weapon systems. This will result in degraded communications, contested logistics flow, protracted decision-making processes, and potential mass casualties. MedCOP provides effective inter-agency and civil-government-military communication and data-sharing paramount in confronting and prevailing in such an event, to include homeland threats and natural disasters. MedCOP enhances situational awareness, facilitates coordinated responses among miliary services and diverse agencies, and optimizes the management of medical resources. By capturing and analyzing real-time information, it enables commanders and leaders to make informed decisions, improve patient outcomes, streamline interagency collaboration inside and outside the medical community, and support effective public health monitoring. MedCOP consolidates data from numerous trusted sources and supports data synchronization across multiple network domains to provide a secure universally accessible and globally integrated medical common operating picture, promoting swift informed decisions in operations and emergencies, ultimately enhancing military operations.
