USCDI

USCDI defines data classes and elements for interoperable health information exchange. These elements can be reused within MedLog records.

​
FHIR

Fast Healthcare Interoperability Resources (FHIR) data formats and elements can also anchor MedLog entries to standardized clinical entities.
AuditEvent.occurredPeriod can represent the execution interval and AuditEvent.recorded can record when the MedLog record was logged.
AuditEvent.agent can identify the immediate calling service, with the account identifier recorded in AuditEvent.agent.who.identifier and security role in AuditEvent.agent.role. When possible, references to Practitioner or PractitionerRole can link the account to the human user and clinical role context.
Target identity can reference an existing Patient, Appointment, or other appropriate resource, with Encounter providing encounter context where applicable.
A software model can be represented by a Device containing its identifier and software version.
Inputs can reference Observation or DocumentReference, for example, while outputs can use FHIR resources appropriate to their clinical meaning, such as RiskAssessment for a risk prediction or DocumentReference for a generated document.
User feedback collected through a defined questionnaire can use QuestionnaireResponse.
These are only illustrative examples of the many possible FHIR fields which could be used to represent or reference information in MedLog records. The field mapping explorer shows the full set side by side with USCDI and OpenTelemetry.
