File Formats
Clinical supports Investigations Results transferred in HL7 and PIT file formats
There are two industry standard file formats used for transferring Investigations Results information:
- PIT - a simple, text based, space-delimited format without the advanced features of HL7. PIT files may be found embedded in an OBX segment of an HL7 message.
- HL7 - the Australian Standard for the electronic transfer of medical information,
including Investigations Results. Further information about HL7 is available from
Standards Australia. Other standards in the HL7 series exist for the transfer of other
clinical information. An HL7 message is broken into segments, each containing specific
information, and identified by an alpha/numeric coded prefix. For example, the result
information is in the OBX segment(s).
- AS 4700.2 - 2004 Implementation of Health Level Seven (HL7) Version 2.3.1 Part 2: Pathology orders and results
- AS 4700.2 - 2007 Implementation of Health Level Seven (HL7) Version 2.4 Part 2: Pathology and medical imaging (diagnostics)
- AS 4700.6 - 2004 Implementation of Health Level Seven - HL7 Version 2.3.1 - Referral and discharge summary
Note:HL7 files may be opened in a text editor, but should not be edited, as this may damage the data, preventing them being imported into Clinical. These files may be difficult to read as they are frequently created without line breaks between segments and they contain large numbers of non-alphanumeric characters. The files are text based, with the data delimited by pipes and carats ( | and ^ ). Currently images or hyperlinks are not able to be received by Clinical. Results containing this type of information cause errors that will abort the import process.
