The FHIR data model. Depicts the metadata (red) and data (blue) FHIR resources and their links that comprise the data model to transform the clinical data from ODM to FHIR. The CarePlan and Questionnaire resources are used to capture the metadata for the study. A Patient resource is used to represent the study participant while the clinical data for this participant is contained within a ClinicalImpression resource. The study events are captured within the EpisodeOfCare resource and the Encounter resource represents one atomic event. The QuestionnaireResponse resource captures the form responses and the Observation resource illustrates those responses that are analogous to a patient’s observations. The QuestionnaireResponse resource is linked back to the Questionnaire resource
