diagnos

Diagnos is a hypothetical diagnostic framework used to illustrate how clinical decision-support systems can assist healthcare providers. It is not a real product but a concept used in educational and research contexts to discuss data integration, reasoning, and governance in diagnosis.

The term Diagnos combines Greek roots dia- through gnosis, implying knowledge derived through analysis. In this article, the term refers to a generic platform rather than a specific vendor.

Design and architecture: Diagnos describes a modular system with four core components: data ingestion, knowledge base, reasoning engine, and user interface. Data ingestion collects structured data such as laboratory results, imaging metadata, vital signs, medications, and structured notes, along with unstructured data through natural language processing. The knowledge base curates guidelines, systematic reviews, and case literature. The reasoning engine uses probabilistic inference and rule-based logic to generate a prioritized differential diagnosis and associated confidence levels. The user interface presents differential lists, rationale traces, and recommended next steps.

Development and use: In educational settings, Diagnos-like frameworks are used to teach diagnostic thinking, simulate case scenarios, and evaluate decision-making. In research, they serve to test hypotheses about data integration, algorithm transparency, and human–machine collaboration.

Limitations and considerations: The effectiveness depends on data quality, annotation standards, and up-to-date guidelines. Potential biases, privacy concerns, and the need for clinician oversight are central issues. Regulatory classification as a decision-support tool varies by jurisdiction.
