I didn't know about section archetypes, but now that you mention it, I see that's what I've actually used - openEHR-EHR-SECTION.investigations_results_rcp.v1

I was thinking about grouping in the model - essentially what I've done is to rename the section archetype "Biometrics, Vital Signs and Investigation Results".

From what you say, it sounds as though that's an acceptable way to organise/categorise  the archetypes within that section.

On point 2, I'll try the problem diagnosis archetypes approach initially  and see how I get on.

Cheers

Hi Grant

1. I'm not sure if you are asking about the groupings in the ui or in the models. Non invasive blood pressure could appear wherever it makes most sense for you. You can also use section archetypes to group items in the composition but I would never want to imply meaning by the parent grouping. A blood pressure is a blood pressure whether you consider this locally to be best grouped under examination or investigation. Headings are useful but in openehr the querying is designed to be able to ignore the section archetypes.

2. Is a tricky question as it partly depends on who is asking the question, why and what ought to happen if someone picks up a new diagnosis. Should this be added formally as a diagnosis to the patients record.

The pure but more complex approach is to handle this with a set of problem diagnosis archetypes to capture positive responses and exclusion archetypes to handle the negatives. This has the benefit of the data being collected in more reusable and codsble way but is more annoying to hook up to the ui.

The quick and dirty alternative is to create a local archetype with a set of booleans that just ask angina yes no. Easy to fit the ui but essentially throw away.

    Hello All, been doing a bit of work (with help from Ian McNicoll)
    on an OpenEHR template for surgical pre-operative assessment.

    You can view the results of my efforts (and Ian's) here :

    https://github.com/johngrant4est/surgical_preassessment

    and I'm not sure how this works in terms of sharing but the
    working repo is here :

    
https://ehrscape.marand.si/designerv2/#/designer/repos/surgical_preassessment

    The template is being built in the form of a Report, which sort of
    matches the real world, in as much as someone does the assessment
    which is then made available as a report.

    I have 2 challenges currently :

    1. How to group the concepts of Biometrics, Physiological
    variables e.g. Vital Signs and Investigation Results e.g. labs,
    radiology. These all feel as though they should be grouped somehow
    as part of the assessment but there is a conflict (in my head)
    between the archetypes for investigations_results and exam
    findings. Is NIBP an investigation or an exam finding ? I
    appreciate that the line between these concepts is a bit blurred.

    2. How to model the typical systematic enquiry when taking a
    history relevant for peri-op care, e.g. how to record the presence
    of angina, hypertension, heart failure, murmurs and group them
    under "Cardiovascular".

    Any thoughts ?

    Cheers

    Grant
