CDA defines several "levels" that identify the expected amount of computable data in a clinical document. Any document with "entry" elements is assumed to be a level 3 CDA.
However, the current approach for referencing graphics in the narrative block requires the use of an entry element as follows:
<text>Erythematous rash, palmar surface, left index finger. <renderMultiMedia referencedObject="MM1"/> </text> <entry> <observationMedia classCode="OBS" moodCode="EVN"> <value mediaType="image/gif"> <reference value="lefthand.gif"/> </value> </observationMedia> </entry>
This means that any document with a graphic is "level 3".
And also it seems like we are forcing people to jump through hoops just to reference a gif.
- Something like the following would be preferable:
<renderMultiMedia mediaType="image/gif" value="lefthand.gif"/> ... or if we decide to allow XHTML in the body: <xhtml:img src="lefthand.gif"/>
Recommended Action Items
March 09, 2010: For attested images, we need full RIM context. For non attested images, there is a simpler way to reference, using established narrative block markup. abstain: 0; opposed: 0; in favor: 8.
