Hi NEWS2 archetype requires a trigger to select SpO2 scale 1 or SpO2 scale 2, the ‘default’ being the former and the exception being scale 2. The trigger is a clinical decision to put a patient on scale 2, based on an arterial blood gas result indicating the patient has hypercapnic respiratory fa…

Thanks Thomas I’m aware of Attributes available in the archetypes but have no concept of how to use these to collect data at the user interface. We are using Better Form Builder and I see no surfacing of Attributes in that but perhaps it has to be scripted into a generic field. I feel that my kno…

Thanks for the clarification, Ian. I think I understood the use case, but was nevertheless trying to decompose the problem. Please correct me if I’m wrong. I’m not acquainted with the depths of the News scales. But BTS and other respiratory authorities have been wisely advocating lower SpO2 target…

It’s more than likely that I just don’t know how to do it. I will ask Better

@NeillY - on the template view you can click on a button that exposes lower-level RM attributes that can be incorporated in the form. You can see composer, ism_transition attributes , start_time etc. However not participations. They are supported in the Better CDR and I have used scripting in other…

@ian.mcnicoll are you able to provide an example of scripting to surface participations? Thanks Neill

Not off-hand, sorry. I think it is possible but you would need to ask Better for an example. I’d also ask then to support participations and the Entry.provider attribute properly in Studio.

Better are planning to incorporate RM attributes in a future release (but they all say that, don’t they :grinning:). Assuming the person completing the form is the authorising clinician, then I guess Composer will be sufficient? We’ll work it out. Better has some interesting documented advice on …

[image] NeillY: Better are planning to incorporate RM attributes in a future release (but they all say that, don’t they :grinning:). Yes, they do, and it’s somewhat alarming. Published archetypes in the international CKM are created with the explicit expectation that all RM elements are usabl…

Yep - not having those RM attributes available to downstream tools is quite a serious problem. Vendors take note please!

Excellent . Do we need to also have a local codesystem, for folks who can’t use SNOMED for licensing reasons? Or is this something to negotiate with SNOMED as a set of free terms?
