Intercoder Reliability of Mapping Between Pharmaceutical Dose Forms in the German Medication Plan and EDQM Standard...

Area of Science:

• Health Informatics
• Pharmaceutical Sciences
• Interoperability Standards

Background:

• Germany has implemented a national medication plan to improve therapy safety and quality.
• The plan aims to enhance usability and interoperability among healthcare stakeholders.
• Semantic interoperability is crucial for effective eHealth implementations.

Purpose of the Study:

• To evaluate the semantic interoperability of the German medication plan specification.
• To assess the mapping of pharmaceutical dose forms to European Directorate for the Quality of Medicines & HealthCare (EDQM) standard terms.
• To determine the inter-coder agreement for coding dose forms.

Main Methods:

• The study involved multiple coders mapping pharmaceutical dose forms from the German medication plan specification to EDQM standard terms.
• Cohen's Kappa (κ) was used to calculate the level of agreement between coders.
• The semantic interoperability of the medication plan specification was reviewed.

Main Results:

• Less than half of the pharmaceutical dose forms could be successfully coded using EDQM standard terms.
• The inter-coder agreement, measured by Cohen's Kappa, was moderate, indicating unconvincing consistency.
• The study identified challenges in utilizing standardized international vocabulary.

Conclusions:

• There is significant room for improvement in adopting standardized international vocabulary for medication data.
• The current coding consistency suggests limitations for seamless cross-border eHealth initiatives.
• Further development is needed to optimize the German medication plan for future eHealth implementations.
