Comment:

Contsys has an informative but for the system of concepts important model of the clinical process. This gives possibilities for interoperability when it comes to clinical context. E.g distinction between investigations and treatment, basic or alternative treatments and so on are possible to define by the use of standardized context based on this model. Encounter is just one kind of "context" that could be needed to state in a resource (see observation.encounter). Other example that could be needed is clinical process concern, demand for care, main health issue health problem or episode of care.

Create a new element to add, in all resources, and replace "encounter" with this in resources there "encounter" is used as a context reference. The element should be of different types: Identifier|Reference(Encounter|EpisodeOfCare|ClinicalProcessConcern). For some of the clinical contexts will require new resources, simulare to episode of care.
