Intro

The use of content modules in XDS-Lab helps lab remain consistent with what other domains have accomplished as well as insures that the lab domain provides guidance to the other domains that as they incorporate relevant laboratory data into their content profiles.

Benefits:

  • Consistency with work done in other domains (see annotation comment)
  • Provide guidance to other domains incorporating laboratory data (example PCC - ?profile)
  • 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 an adaptation (CP potential!) of [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. This example provides a reason for adaptation to the current content module.

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.
