Topic: Admission ID

Where does one find Admission ID?
Is it one of the identifiers of an encounter that represents the encounter with an institution?
Is there and ID Type or something that flags it as the Admission ID?

@Brian Postlethwaite ?
Kevin O'Donnell (Feb 23 2019 at 00:16):
Sorry, I thought Admission ID was more widely recognized. In HL7 it would be PV1-19-Visit Number.
Lloyd McKenzie (Feb 23 2019 at 00:48):
We typically call that "Encounter id", but whatever you call it, it would go in Encounter.identifier
Kevin O'Donnell (Feb 23 2019 at 00:54):
OK. In the case where there is an admission encounter and then a subordinate department encounter, I assume the Visit Number would only go in the encounter.identifier of the admission? And if so, what is the practice for identifiers for department encounters? (or clinician encounters)?

FHIR runs 24x365 :) I don't know that there's necessarily a common "practice". If you split the admissions process into a separate encounter from that of the various department visits, I suspect you'll have an encompassing encounter that groups them all. There's no standard scheme for assigning identifiers - any more than there's a standard scheme for what constitutes a distinct encounter and when or how to use sub-encounters. FHIR allows conveying whatever business concepts you have, but we're a long way from trying to standardize business practices even in a single country, let alone across all types of healthcare and all countries.

Identifier.type has an extensible value set drawn from http://terminology.hl7.org/CodeSystem/v2-0203. That code system has "VN" defined for visit number. Is there a reason VN is not in the Identifier type value set? Is anyone populating the identifier type for visit number/admission identifiers?
René Spronk (Feb 24 2019 at 09:25):
@Kevin O'Donnell As Lloyd mentions it's up to you, given your context. There are countries/contexts where PV1-19 contains the id of the organisational-encounter, but other contexts where the identifier would be at another hierarchical encounter level. Most people are interested in PV1-19 to track/group billable stuff. Some contexts use 4 different levels, all with their own unique identifier.
Kevin O'Donnell (Feb 27 2019 at 00:42):
@Lloyd McKenzie @Rene Spronk Elliot's suggestion to look in Identifier.type to see which one is indicated to be the VN (visit number) seems like it would work. Is there a reason not to do that?

Lloyd McKenzie (Feb 27 2019 at 01:04):
I wouldn't necessarily count on systems disambiguating there, but yes, you could use different types.
