Hồ sơ tài nguyên: Phân loại ưu tiên cấp cứu VN Core — VN Core Triage Acuity Observation

URL chính thức: http://fhir.hl7.org.vn/core/StructureDefinition/vn-core-observation-triage-acuity Phiên bản: 0.6.0
Computable Name: VNCoreObservationTriageAcuity

Bản quyền/Pháp lý: Căn cứ pháp lý Việt Nam: QĐ 01/2008/QĐ-BYT ngày 21/01/2008 (Quy chế Cấp cứu, Hồi sức tích cực và Chống độc); TT 13/2025/TT-BYT ngày 06/06/2025.

Profile Observation ghi nhận mức độ ưu tiên phân loại người bệnh tại khoa Cấp cứu (5 cấp độ) per Quy chế Cấp cứu, Hồi sức tích cực và Chống độc (QĐ 01/2008/QĐ-BYT). Dùng trong lượt cấp cứu (Encounter.class=EMER) để ghi mức ưu tiên triage do điều dưỡng/bác sĩ phân loại. Căn cứ pháp lý:

  • QĐ 01/2008/QĐ-BYT (21/01/2008) — Quy chế Cấp cứu, Hồi sức tích cực và Chống độc (phân loại ưu tiên người bệnh cấp cứu)
  • TT 13/2025/TT-BYT — bệnh án điện tử ghi nhận diễn biến cấp cứu. / VN Core triage acuity Observation for emergency department patient prioritization (5-level scale).
