An overview of the standards that the project considered in the development of a multipurpose care plan strategy.

Domain of standards	Names of standards that have been addressed	Rationale
Vocabularies	SNOMED CT, HL7 2, LOINC, ICHOM, ICD10/11	Vocabularies cover different ontological domains, and several are needed to build a care path. The local annotation with retained reference to provenance allows multiple standards to be used
Carepath support	OpenEHR, HL7 FHIR PlanDef/CarePlan	A number of standards exist. FHIR suited our purposes with its flexibility and growing adoption
Data reporting	FHIR Observation, FHIR Forms, OMOP, CDISC	FHIR observation is flexible, handles reference to care plan and readily translates into OMOP/CDISC
Representation of data collections	International Patient Summary, Medication list, Queries	These were broken down to term level and the components were represented in the local vocabulary allowing reconstruction to the protocols in the data reporting
Authentication	Smart on FHIR	Active monitoring of data communication protocols and security
