Draft editorial guidelines: Editorial Guidelines for Diagnostic Products Used for Susceptibility Testing

It was decided to recommend representation the physical form of the susceptibility test product, and also to use the | has presentation strenght... | attributes (as opposed to other strength attributes).

See comments on this page.

The FSNs are generally under-specified compared to how concepts have been used. We need to decide whether to retire, rename, remodel, add or leave as is.

E.g. the blood pressure observables FSNs do not specify time aspect. Can we assume that they are single point in time or not?

The guidance given by the EAG was that we should allow more consideration of reasonable clinical interpretation and also to allow updating and clarification of FSNs if deemed necessary. Data concerning clinical use of the concepts should be used to inform decisions. Ambiguous concepts which are not in significant use may be retired.

As this might disrupt implementations the updated guidance should be discussed with the MF and CMAG.

We have previously had some discussions of extending the concept model to encompass additional attributes and allowed values.

These include:

• | Direct substance | - analog to | Direct site |, e.g. a protein substance could be a proxy for genetic configuration, with the range of << 105590001 | Substance |.
• Extend | Technique | allowed values to include << | Assessment scales | - was discussed previously (long time ago) to allow representation of Assessment scale observables. Scales typically includes an instrument used to collect information.

It was decided to recommend making the above changes to the MRCM.

Copied from the Vital signs incept./elaborat. document:

Target observables

Among the 46680005 | Vital sign (observable entity) | observables, there are a few "target" observables: 428420003 | Target heart rate (observable entity) |, 315612005 | Target systolic blood pressure (observable entity) |, and 315613000 | Target diastolic blood pressure (observable entity) |. These concepts would not be considered vital signs according to the definition used in this document. While the representation of such targets have not yet been elaborated on, it is clear that a target observable is distinct from a "ordinary" observable, particularly true for e.g. 390734006 | Target weight (observable entity) | and 27113001 | Body weight (observable entity) |. There are related JIRA tickets: IHTSDO-457, PCP-5, IHTSDO-39 and also some potentially related tickets: IHTSDO-356, IHTSDO-308.

Here is a presentation from a previous Observables meeting.
