Some of these Contsys definitions are problematic:

Hi Karsten,

ISO System of Concepts for Continuity of Care (ContSys) defines all kinds of concepts related to care and its documentation.
It would be. a good thing to harmonise terms we use.
More info via: https://contsys.org

ContSys is *_NOT_* a Data model but a way to define concepts and there relations using UML.
It can/must inform the production of shared archetypes.

ENCOUNTER
Most certainly this is the case when a Healthcare Provider meets the patient and documents the care given.
Meeting can be real and virtual via telephone, e-mail, a third party

But there is an encounter when the HcP interacts with the EHR without a Patient (Virtually) present.

that would certainly be a subversion of the usual meaning of 'encounter' (literally 'to meet') in English and all the latin languages at least... (in Portuguese and Brazil health system, the word is 'atendimento', i.e. attendance... - probably the same in Italian and Spanish).

It would be better ontologically to call such an event something else - in openEHR it is a commit of a Contribution.

There are also other health system actions with the patient absent, e.g. doing lab work on tissue samples - also real 'work', but not an encounter.


So ENCOUNTER, in my terms, is any interaction of an Author (HcP, Patient, third Party/Proxy) with the Patient Record.

The ISO standard System of Concepts for Continuity of Care uses the term and definition: /*contact <https://contsys.org/concept/contact_period>*perio <https://contsys.org/concept/contact_period>d-healthcare activity period <https://contsys.org/concept/healthcare_activity_period>during which acontact <https://contsys.org/concept/contact>occurs/

EPISODE
ContSys defines this as:
/*episode of care-*health related period <https://contsys.org/concept/health_related_period> during which healthcare activities <https://contsys.org/concept/healthcare_activity> are performed to address one health issue <https://contsys.org/concept/health_issue> as identified by one healthcare <https://contsys.org/concept/healthcare>professional[/

I would suggest that most people think an episode of care is not limited to one HCP, and is not always limited to one health issue, even if there is usually one main 'problem' on admission. An episode of care is usually thought of as care to resolve an issue for a patient by a team of HCPs working in an integrated environment, e.g. a hospital. If the resolution of the issue requires care that crosses institutions (usually the case), then a different term is probably needed for that.
