Description
In Laboratory the ordering provider of an initial test may wish to have further tests use the specimen already collected, or to be collected for another test. The proposal is to create an extension that accommodates specifying another ServiceRequest that yielded the specimen of interest rather than explicitly referencing the specimen(s) to use as those may not be known/identifiable to the ordering provider.
Proposal to add:
- ServiceRequest.extension-specimenSuggestion 0..* Backbone Element - This attribute enables the requester of this service to indicate they would like a certain specimen to be used, but if that is not available/appropriate to be used whether to have another specimen drawn, or that this test is not performed.
- reference 1..1 Reference(Specimen|ServiceRequest) Description: References the specific specimen or the service request that yielded the specimen that is preferred to be used
- fallBackAction 1..1 code (new | cancel) Required binding:
- new - draw a new specimen if the suggested specimen cannot be used
- cancel - do not perform the test if the suggested specimen cannot be used (would require communication from the lab when it ended up canceling)
Proposal to modify:
- ServiceRequest.specimen comments:
- When a specimen is referenced it is expected to be used. If it cannot be used, the decision to collect another specimen or not perform the test must be based on established policies or determined in some other agreed to way with the requester.
