Phase II work for LCS content:

• Update the content to the latest version of CPG (applied)
• Publish the content on fhir.org/guides (in-progress)
• Publish the content in CDS Connect (waiting on publication on fhir.org)

It’s likely the following will change in the near future:

• URL reference to the USPSTF guideline (it’s being updated now -- https://www.uspreventiveservicestaskforce.org/uspstf/draft-update-summary/lung-cancer-screening1)
• 30 pack year requirement à 20 pack year requirement
• 55-80 age requirement à 50-80 age requirement

Steps to apply this update:

1. Update the version of the implementation guide

Update the version element of the lcs-cds Implementation Guide resource

This change will be automatically applied to all the resources published as part of the IG.

2. Update any references

If the URL of the recommendation changes, change it where it appears:

1. LCS Recommendation Page
2. Library Related Artifact Citation
3. PlanDefinition Related Artifact Citation

3. Update the logic

Update the CQL logic:

1. Expression "55 through 80" to determine the age, needs to be renamed to reflect age change as well as the logic
2. Expression "Has 30 pack-year smoking history", needs to be renamed to reflect the change in years, as well as the logic
3. Expression "Inclusion Criteria" will need to be updated to reference the updated criteria expressions.

4. Refresh the artifacts

Run the _refresh.bat or _refresh.sh script as appropriate for your environment (Windows vs Linux) to refresh the generated content in the Library resource.

5. Rebuild the IG

Run the _genonce.bat or _genonce.sh script to rebuild the implementation guide. This should result in a clean build with no errors.

6. Commit the change to the repository

Commit the change to the lcs-cds repository, this will kick off the auto-build and update the CI Build.

7. Release

Submit the updated content for release to the FHIR foundation, and CDS Connect repositories.
