Thanks Grahame, but I disagree.

“•          A generic question/answer pattern is next to useless - interoperability is really not helped, especially if both the question and answer has to be managed in the template.”

The complete sentence qualifies that the dependence on template modelling is the issue wrt interoperability. This is where a generic pattern is made specific for a given questionnaire or data set. Also that we have found there are multiple generic patterns, none of which is universally applicable and so to create multiple generic patterns becomes nonsensical.

In the templating scenario it is only if the exact same template is shared (where every question has been renamed and associated value sets inserted) that can we get any value. In our experience it is of higher value to create an archetype that can at least be shared locally and explicitly models the precise question/answer combo in order to achieve better reuse.

hi Heather

I think you should rather say "A generic question/answer pattern is only useful for exchanging the questions and answers, and does not allow re-use of data". This is not 'next to useless for interoperability', just not fit for any wider purpose

Following Thomas’ suggestion re a separate thread:

I wrote a blog post in 2014 which still reflects our current thinking re questionnaires: https://omowizard.wordpress.com/2014/02/21/the-questionnaire-challenge/

Our experience is that the data is the priority and so we want to focus on questionnaires to support capture of good quality data.

If you want to try to capture data from the majority of existing questionnaires then good luck – questionnaires notoriously ask questions badly, conflating multiple concepts into one question, Boolean True/False when there are other ‘shades of gray’ etc. They work variably as far as human interpretation but usually very badly wrt computer interpretation.

We do have experience in taking previous paper questionnaires, analysing the data requirements sought in terms of what we want to persist and then we design the UI/questions to match the data desired and/or suggesting the UI might show a questionnaire but each question the clinical data is actually recorded using core archetypes – for example “Do you have diabetes?” – ‘Yes’, is recorded using the value ‘Diabetes’ in the EVAL.problem_diagnosis and ‘No’ is recorded in the matching exclusion archetype. This creates real clinical data that can be used as part of a health record rather than create an electronic checkbox version of the original paper questionnaire which will never be used again, but capture dust in our EHR’s virtual archives.

In summary:

  *   A generic question/answer pattern is next to useless - interoperability is really not helped, especially if both the question and answer has to be managed in the template. We have tried many variations of this in the past, some of which were uploaded into CKM and subsequently rejected.
  *   Lock in those questionnaires that are ubiquitous, evidence based, validated as OBSERVATION archetypes and share them in the international CKM – eg AUDIT, Glasgow coma scale, Barthel index, Edinburgh post natal depression scale – there are many examples in CKM.
  *   Lock in local questionnaires that are going to be reused in your organisation, region or jurisdiction even though they may not be reusable elsewhere. They will provide some interoperability even if might only be appropriate within one clinical system or national CKM. An example is the Modified Early Warning Score/National Early Warning Score – there are a few different variations used in different locations and whether they should all be in the international CKM is still not clear.

BTW Questionnaires should be modelled as OBSERVATIONs (ie evidence that can be collected over and over again using the same protocol) not EVALUATIONS (as they are not meta-analysis nor summaries).

Subject: Re: Reports - a new openEHR RM type?

Besides specific ways to model questionnaires, my questions is if our openEHR clinical modelers have a pattern to represent questionnaires using the openEHR information model.

There are several kinds of context archetypes/templates and their meta-data are used for:
- de novo data - re-used data
- step in the clinical treatment model (observation, assessment/inference, planning, ordering, execution)
- kind of interface it is designed for (data presentation on a screen, data capture, database store/retrieve, CDSS, …

Each Template needs to capture all this and is a Composition.
All these contexts are characteristics of a Composition in the end.

Questionnaires are in essence a tool that classifies information.
And sometimes it transforms a set of responses into an aggregated value/code
The questionnaire can be treated as any classification, meaning we need to de fine inclusion and exclusion criteria,
and possible results per question can be a quantitative result (number, PQ, code), or a semi-quantitative result (high, low), or a qualitative result (present/ not present).
Semi-Qualitative results need, inclusion/exclusion criteria and a definition of what the norm/population is is about (females, children, etc.)

Hi Thomas,
Thinking about the hierarchy, at which level will be a Report be? Below compo? Below entry? Structure? Representation?
OT: many asked me this and didn't had a good answer. Do we have a pattern to model questionnaires? Some require to define questions, and the answer type in most cases is boolean, or coded text (multiple choice), and answers might be 0..* (more than one answer for the same question is valid).
Cheers,
Pablo.
