Existing Wording

The current 1.1 eICR IG does not include any guidance for eICR versioning, either replacing an eICR with a new eICR or appending an eICR to another eICR document.

Proposed Wording

Although the CDA base standard allows for documents to be replaced or appended, it is recommended to constrain out “appended” eICR documents in the eICR IG. Unlike replacement documents, for appended documents, the parent document remains a current component of the patient record. Therefore, all appended “addendums” and its parent are all read by report recipients. This means integrated disease surveillance systems will always have the current information about an event in one document (the most recent), with no processing overhead but at a possible cost of increased storage. If a complete history of the reporting is needed, the system will have to maintain a copy of all of these eICR documents, which will introduce storage capacity issues and processing capacity issues within the disease surveillance systems.
