What is ELGA?

ELGA (Elektronische Gesundheitsakte = EHR)

ELGA contains relevant multimedia-based and health related data and information referring to a precisely identified person.

Data und information originate from different health service providers and from the patient himself/herself

and are stored in one or several different information systems (virtual health record).

Data are available independently of place and time (cost-saving) at the place of treatment for all authorized persons according to the tasks and needs of these persons and in compliance with data protection rules

Laboratory

Experts group of about 50 persons mainly specialists in laboratory medicine (private or hospital

laboratory), but also laboratory IT vendors, experts for medical informatics, and HL7 experts

Goal: develop a nationwide harmonized report definition for laboratory and microbiological studies

CDA document with fully defined level 2 and level 3 Two phases

Harmonizing medical content based on requirements of Austrian Society for Laboratory Medicine

January 2008 – May 2008 Finish definition of harmonized medical content +

microbiology studies, technical implementation December 2008 – March 2009

Advanced handling of specimen information Condition, comment, responsible persons, …

Chief complaint or admission diagnosis Taken from order

Multiple reference ranges with different preconditions for one test

Subcontracting laboratory Tests have to be marked

Complex comment structure specimen, test, report section, whole report

Evaluation …

Evaluated international work on CDA lab reports Germany (VHitG / HL7) Italy Finland IHE …

Decision for IHE XD-Lab (Lab TF – Vol. 3) VHitG model was firstly preferred but does not fulfill

the Austrian requirements IHE covers most of Austrian use cases Multinational solution Also includes microbiology studies

Constraining level 2

IHE XD-LAB contains only a number of recommendations

Acc. to IHE sections are “DRIV” rules for mapping level 3 to level 2 required

To get a similar structure and layout for the laboratory report all over Austria it was necessary to strictly constrain the level 2 coding and the associated display of the medical content. Type of elements

(e.g. specimen information) Fields (order, coding) Order of elements …

Further challenges …

Coding and order of report sections List of specialities not fitting the requirements

Microbiology studies Coding “same” isolate with different cultures (ongoing

discussion)

Rendering footnotes: unclear definition of <footnote> and <footnoteref> in the CDA definition. No appropriate example could be found

Hard to fulfill IHE requirements e.g. on address and telecom

Problems Vocabulary

LOINC and other code lists: Quality assurance for translation and adoption process for Austria is neither fully defined nor finished

Coding of microorganisms (isolates) no candidate vocabulary for the coding of

microorganisms, since SNOMED CT is not available in a German version and in addition: Austria is not a member of the IHTSDO

Semantics of interpretation codes
