In the US, we have this very specific type of Visit called an “Observation” visit. Currently, we map it to visit_concept_id = 0, since there isn’t a concept_id for this. Now we are re-visiting this decision. WWCD? (What would @Christian_Reich do?)
The Person may be in the hospital being observed for a few hours or the Person may be observed overnight or more. Since a Person hasn’t been given a formal “admit as inpatient” order from the Provider, do others map this to visit_concept_id = outpatient? This is Medicare’s point of view. However, a Person may have an ER Visit, then an Observation Visit and then an Inpatient Visit. And the Observation may take place in a department of the inpatient hospital. The care site varies, but when the care site is an inpatient department, the Visit seems more like an inpatient visit from a world-wide/OMOP point of view. It’s just not labeled by the hospital as an inpatient visit. How should we map this? And can we get a visit_source_concept_id = ‘observation visit’, so we can distinguish it from other visits?
