The "Achieving Interoperability of Medical Systems Act of 2025" directs the Secretary of Defense and the Secretary of Veterans Affairs to jointly implement interoperable image-sharing software technology. This technology is intended for use across all military health service facilities, including the GENESIS platform, and Department of Veterans Affairs medical facilities, encompassing their Federal Electronic Health Record platform. The scope of this interoperability extends to military medical centers, VA medical facilities and clinics, and non-Department providers who have agreements with the VA. The primary goal is to enable seamless sharing of medical images and related clinical data, thereby improving healthcare delivery and reducing the need for repeat imaging. Within 180 days, the Secretaries must submit a detailed plan and timeline to Congress for achieving full interoperability, which includes assessing current capabilities, expanding vendor contracts, and identifying specific software solutions. The chosen technology must meet stringent technical requirements, such as accessibility standards, synchronous data exchange, mobile compatibility, and adherence to industry standards like SMART on FHIR, OAuth2, and DICOM, while also being cost-effective and potentially leveraging artificial intelligence. Ultimately, the initiative aims to improve patient-centered care through faster diagnoses, more informed decision-making, and better communication among providers. It also seeks to enhance staff efficiency, prevent burnout, and promote the effective use of shared services between the DoD and VA, with annual reports to Congress on progress and cost savings.
