URL chính thức: http://fhir.hl7.org.vn/core/StructureDefinition/vn-core-observation-body-temperature | Phiên bản: 0.5.0 | Làm nổi bật phần thay đổi?
| Computable Name: VNCoreObservationBodyTemperature
Bản quyền/Pháp lý: Căn cứ pháp lý Việt Nam: TT 13/2025/TT-BYT ngày 06/06/2025; QĐ 1227/QĐ-BYT ngày 11/04/2025.

Profile Observation nhiệt độ cơ thể cho Việt Nam, dùng LOINC 8310-5 và đơn vị UCUM Cel. Phục vụ ghi nhận sinh hiệu, sàng lọc sốt và theo dõi lâm sàng trong bệnh án điện tử theo TT 13/2025/TT-BYT (06/06/2025). QĐ 1227/QĐ-BYT (11/04/2025) là căn cứ chuẩn hóa thuật ngữ chỉ số cận lâm sàng và ánh xạ LOINC khi triển khai trong nước.
