CDS Hooks

CDS Hooks

Clinical Decision Support (CDS) Hooks is a specification developed by Health Level Seven International® (HL7®) and managed by its CDS Work Group. It enables near real-time decision support to be integrated directly into a clinician’s electronic health record workflow.

When a specified event occurs within the clinician’s workflow, it triggers a CDS service. The service then securely retrieves the necessary data elements using HL7 Fast Healthcare Interoperability Resources® (FHIR®) services. By leveraging FHIR standards, CDS Hooks supports interoperability among stakeholders operating across different systems and platforms.
