This repository includes the FHIR profile definitions, code systems and value sets which constitute the Common Health Data Model used for heart failure research. The profiling was performed with respect to the data requirements originated from the use-case scenarios of the DataTools4Heart and AI4HF projects. Please see the Excel file for the detailed definitions of the profiles.
Profiles are well-defined HL7-FHIR-based representations of healthcare resources, such as conditions, lab measurements or medications. Profiles are used to enforce syntactic and semantic restrictions on resource definitions such as cardinality of a particular element and/or code systems to be used for a coded value.
Standard terminology system that are used in Heart Failure Resarch CDM:
- ICD-10: conditions (diagnosis)
- ICD-10-PCS: procedures
- LOINC: lab, echo and ECG measurements,
- ATC: medications
- SNOMED-CT: symptoms
Value sets are used to restrict values that can be specified for specific elements of healthcare resources. For instance, we have an HL7 FHIR Observation-based profile for New York Heart Association (NYHA) classification, for which we would like to restrict possible values with the four pre-defined classes: I, II, III and IV.
Code systems are a group of codes defined in the scope of DT4H & AI4HF projects for coded representation of particular concepts. For instance, we have defined a code system containing coded values for some echocardiogram measurements that do not have a corresponding code in the available standard-based terminology systems, such as LOINC.
