What are CDS Hooks?

CDS Hooks is a standard for invoking clinical decision support (CDS) from within EHR solutions. It defines a hook-based pattern for executing CDS calls returning information and suggestions to the clinician using an EHR. The external service can be any type of service that provides clinical decision support.

The CDS Hooks standard additionally defines a set of hooks that can be invoked at specific points in the EHR workflow, e.g. patient-view and appointment-book as well as the structure of the request and response messages.
