This is my whole concern in this area - everyone comes to the space with quite different ideas of the meaning of Episode/ encounter based (not unreasonably) on prior experience. The terms Encounter, episode. spell, period are all hugely overloaded., The openEHR Encounter is largely from a primary-care or individual practitioner perspective, your is from an organisaitonal / reporting perspective. Neither are wrong. There have been successive efforts in various places to standardise the ideas. Contsys is the only one that feels to me to have been bold enough to take a truly holistic approach, and not be afraid to use new teminology
That’s why I would strongly suggest using Contsys as the ‘common language’ for these ideas, even if they do not fit anyone’s language properly. They are at least neutral, and sometimes phrased in a way that is a bit weird - e.g ‘Health issue thread’ .
I would map your idea of Encounter to
episode of (health) care time interval during which health care activities are performed by one health care provider to address one professionally defined health issue
spell of care to …
period of (health) care set of contacts between a subject of care and one or more health care professionals in the framework of a care mandate
openEHR Encounter does map to
(health care) encounter contact in the course of which health care provider [FM1]activities are delivered to a subject of care in her or his presence
(health) care mandate health mandate following a demand for care, assigned to, and accepted by, a health care provider to perform health care provider activities, and to manage a local health record
What is important (and where I disagreed with the way Contsys was trying to get adopted) is that we need to expect local organisations and practitioners to defend their local terms - just too hard to get people /systems to drop this.
So my thoughts are that we should name any Contsys artefacts using their terminology but accept that local naming will still be needed. Also that contsys alignment might be best achieved by using cluster extensions, into existing archetypes, RM constructs. The Contsys people wanted to basically build their own RM - that was just never going to happen.
