Details

The National Health Safety Network (NHSN) under the U.S. CDC has published the "ACH Monthly Encounter Status ValueSet" as part of its Digital Quality Measures (dQM) Content Package. This value set provides a standardized set of codes for defining the status of clinical encounters, ensuring that encounter situations are uniformly recorded in medical records. Specific statuses defined include 'in-progress,' 'finished,' and 'triaged.' This Implementation Guide (IG) is built upon FHIR R4 standards, enabling the accurate digital recording of processes from the start to the end of a clinical episode. By doing so, it prevents misunderstandings or omissions in information exchange between different systems, significantly contributing to improved interoperability of medical data. In Japan's healthcare IT sector, standardizing clinical concepts such as patient status and examination progress is critically important. The adoption of FHIR-based code systems like this value set can strengthen the foundational data linkage for electronic health record (EHR) systems and regional cooperation systems, aiding in the development of high-quality telemedicine and emergency response systems.
