Antitrust Statement

Professional Associations, such as HL7, which bring together competing entities are subject to strict 
scrutiny under applicable antitrust laws. HL7 recognizes that the antitrust laws were enacted to promote 
fairness in competition and, as such, supports laws against monopoly and restraints of trade and their 
enforcement. Each individual participating in HL7 meetings and conferences, regardless of venue, is 
responsible for knowing the contents of and adhering to the HL7 Antitrust Policy as stated in §05.01 of 
the Governance and Operations Manual (GOM).

CRMI ballot results

Question: Can prefetch support "observations in the last 10 days" as opposed to "most recent 10 observations"?


CDS Hooks Prefetch Discussion (Status of Github changes)

PR with proposed changes:

Specifically addressing:

The draft proposed PR adds significant flexibility to the syntax of prefetch.

Discussion of a specific clinical use-case which requires retrieving all Observations from the last 10 days. This use-case isn't satisfied by the current draft proposal (we're pretty sure). 

For example, the subset of FHIRPath named "Simple FHIRPath" –Fhirpath - FHIR v5.0.0 ( – explicitly lists the allowed functions, thereby not permitting .today() or .now().

Plan to talk through this topic during: Mon Q4 in FHIR-I (joint CDS), or Tues Q2
