Challenges of Digital Lab Results: The Need for Integration and Standardization in ePA
Digitaler Laborbefund: »Wir sollten einfach mal starten - E-HEALTH-COM E-HEALTH-COM
Summary
A lab medicine expert points out the difficulty of integrating test data into electronic patient records (ePA). Although HL7 and FHIR are used in practice, true unified digitalization requires deep semantic standardization using standards like LOINC and SNOMED CT.

Dr. Andreas Bietenbeck, a specialist in lab medicine, highlights the challenges associated with digitizing laboratory results (Laborbefunde) in Germany. Currently, many processes still rely on paper or fax, leading to significant variability in the transition to digital workflows. While integration of lab data into the ePA is anticipated, current systems using HL7 and FHIR have not achieved true unified standardization. Dr. Bietenbeck emphasizes that achieving 'truly digital test results'—more than just a PDF scan—requires semantic standardization, not merely technical digitization. He specifies that multiple standards must be linked, including LOINC (for units of measure/test items), UCUM (Unified Code for Units of Measure), and SNOMED CT, to systematically map all laboratory services. He notes that this process is continuous and requires the leadership of lab medicine specialists. Furthermore, he points out the complexity in practice, such as how different test scenarios (e.g., glucose tolerance test vs. fasting blood sugar) require distinct LOINC codes even if the underlying assay is identical, demonstrating the depth of standardization needed.
