All options face the same problem: they need to keep a record of their own history (for graphs, triggers and research data). It is likely that the reports themselves (as opposed to the HL7 data they contain) will need to be stored, and these issues will also need to be addressed. A decision has been made that the Personally Controlled Electronic Health Record (PCEHR) database will have a copy of pathology reports in PDF format as pathology laboratories prepare them. The same format can be used to store our enhanced reports in the PCEHR database.
