Laboratory medicine: Confirming diagnoses and supporting treatments – quickly, efficiently and correctly.

Diagnostic Pathways

From indication to transmission of findings

The working group Diagnostic Procedures was founded in 2006 with the objective of supporting the diagnostic process in terms of content, organisation and information technology. The focus is on medical laboratory  examinations.

Special concerns:

  • Consideration of scientific recommendations and guidelines
  • Alignment with medical and economic needs
  • Implementation in hospital information systems and laboratory information systems (KIS, LIS)

Diagnostic pathways and treatment pathways are equally valued components of clinical pathways. With the introduction of diagnosis-related blanket rates per case (DRGs) and the rapid increase of new diagnostic tests in the genome era, the standardisation of requirements and decision-making processes in the form of such paths has become increasingly important.

  • A diagnostic pathway describes the entire process from the test request to the interpretation of the findings, both in terms of content and time
  • It contains test indications (WHAT) for medical questions (FOR WHAT), supplemented by the indication of times (WHEN) and justifications (WHY)
  • The representation is mostly graphical (decision trees, flowcharts), but the WG also examines other forms of representation (rules, mathematical functions, etc.)

The results of the WG are published on the DGKL website, in the publication media of the Society (J LabMed, KCM) and in reference books.
