USPSTF_Screening_for_Abnormal_Blood_Glucose_and_Type2_Diabetes_FHIRv102 (FHIR DSTU2)
=========================================================================================

-----------------------------------------------------------------------------------------
VERSION 1.0.0
-----------------------------------------------------------------------------------------

Initial FHIR DSTU2 version that was piloted in 2019.

-----------------------------------------------------------------------------------------
VERSION 1.1.0
-----------------------------------------------------------------------------------------

Version 1.1.0 was updated based on terminology review. As a result of this review,
the CQL logic was updated in the following ways:

- Removed retired SNOMED-CT code "Polycystic ovaries (disorder)"
- Added value set "Polycystic Ovary Syndrome" (2.16.840.1.113762.1.4.1032.151)

USPSTF_Screening_for_Abnormal_Blood_Glucose_and_Type2_Diabetes_FHIRv102 version
1.1.0 has not been piloted in a clinical setting, but has undergone logic testing
and review.

=========================================================================================
USPSTF_Screening_for_Abnormal_Blood_Glucose_and_Type2_Diabetes_FHIRv401 (FHIR R4)
=========================================================================================

-----------------------------------------------------------------------------------------
VERSION 1.0.0
-----------------------------------------------------------------------------------------

The USPSTF_Screening_for_Abnormal_Blood_Glucose_and_Type2_Diabetes_FHIRv401 version
1.0.0 library is a FHIR R4 port of the
USPSTF_Screening_for_Abnormal_Blood_Glucose_and_Type2_Diabetes_FHIRv102 version
1.1.0 library. While the intent of the logic remains the same as the FHIR DSTU2-based
version, changes in the FHIR specification (from DSTU2 to R4) require additional
changes in the CQL logic. This R4 representation contains the following changes
related to the movement from FHIR DSTU2 to FHIR R4.

- FHIR data model is now version 4.0.1
- FHIRHelpers is now version 4.0.1
- CDS_Connect_Commons_for_FHIRv102 has been replaced by
  CDS_Connect_Commons_for_FHIRv401 version 1.0.0

In addition to porting the data model, it also leverages new IGs and profiles,
resulting in the following additional changes from the DSTU2 version:
- Uses US Core v4.0.0 Race extension and associated codes / value sets
- Uses US Core v4.0.0 Ethnicity extension and associated codes / value sets

The following additional changes were made based on new capabilities in later
versions of the CQL spec and tooling:
- URL-based value set identifiers are used rather than plain OIDs
- code/concept pairs are no longer needed; code definitions are sufficient, so
  concept definitions have been removed
- The FHIR modelinfo was updated to properly reflect extension URLs as FHIR.url
  types, so CQL was adjusted accordingly

USPSTF_Screening_for_Abnormal_Blood_Glucose_and_Type2_Diabetes_FHIRv401 version
1.0.0 has not been piloted in a clinical setting, but has undergone logic testing
and review.
