PCC TF-1/PHLAB/XDSLAB Harmonization

Back to: PCC_TF-1/PHLAB

Intro

The use of explicit content modules in XDS-LAB will help other domains that are incorporating laboratory data be consistent.

• Provide purpose to section of CDA (see annotation comment)
• Provide context to section of CDA (see intended recipient)

Annotation Comment (PCC)

Laboratory reports come with at least 3 tiers of comments (result, test, report). We would like XDS-Lab to adopt the PCC-TF Annotation Comment content module for test and report comments and to provide samples demonstrating Level 3 references to Level 2 content.

Result and Test level comments

XDS-Lab

• result - footNote
• test - similiar to PCC-TF Annotation comment with proposal to extend schema on the observation

We recommend placing test level comments them within the observation/

block using <tfoot> blocks. For consistency, we recommend re-use of the existing PCC-TF Annotation Comment content module within Level 3 Entry linked to the Report_Entry <entry><act> and <><> as shown in this example.

Report level comment

XDS-Lab report level comments are placed within the <text> block using <paragraph> blocks. For consistency, we recommend re-use of the existing PCC Annotation Comment content module within Level 3 Entry linked to the Report_Entry <entry><act> as shown in this example.
