Hi all

To me a "questionnaire" is a vague notion. There can be a lot of different 
"questionnaires" in health. From the GP's in Thomas's example to a Apgar score, 
to a clinical guideline and even a checklist. Those are all a set of "questions 
and answers", but the scope and use is totally different. In paper 
questionnaires we will find a mix of many, maybe all, of those, crammed into 
what the local practice have found to be useful (= "Frankenforms"). To try to 
put all of them into a generic questionnaire-archetype is of no use.

Examples:
The GP questionnaire referred to by Thomas is in the quoted question about 
"ever had heart trouble" merely a help for the GP, and of little use for 
computation. But if it is supplemented by more specific questions, based on 
answers by the individual, then the final result can be "occasional arrhythmia 
with ventricular ectopics", which is a relevant information for later use and 
should be put into a relevant archetype. So is it a "questionnaire" or a 
guideline for the consultation? Not relevant IMO, it's the content, that's 
relevant.

Patients with haemophilia in Oslo university hospital are offered a 
questionnaire online to register whether they've had incidents of bleeding, 
what caused it, if they needed medications and if so, the batchnumber of the 
medication. This is followed up by the staff both for reporting of used 
medication, and for the patients next follow-up out-patient control or 
admission. Questionnaire or not? Not relevant - it's what the information is 
and what it is for, that is important. Find relevant archetypes for them, 
OBSERVATIONS or ADMIN-ENTRY for this, I guess.

Even checklists are a set of questions and answers. "Have you remembered to 
fill out the diagnosis?". "Is there a need to offer the patient help to deal 
with the cancer diagnosis?". Main thing is to analyze what the resulting answer 
is representing, and the use of it. Decision support? Clinically relevant? 
Merely a reminder? Put them into a template, using appropriate archetypes.

this has to be essentially correct, I think. If you think about it, scores (at 
least well designed ones) are things whose 'questions' have only known answers 
(think Apgar, GCS etc), each of which has objective criteria that can be 
provided as training to any basically competent person. When score / scale is 
captured at clinical point of care, any trained person should convert the 
observed reality (baby's heartrate, accident victim's eye movements etc) into 
the same value as any other such person. In theory, a robot could be built to 
generate such scores, assuming the appropriate sensors could be created.

With 'true' questionnaires, the questions can be nearly anything. For example, 
my local GP clinical has a first time patient questionnaire containing the 
question 'have you ever had heart trouble?'. It's pretty clear that many 
different answers are possible for the same physical facts (in my case, 
occasional arrhythmia with ventricular ectopics whose onset is caused by 
stress, caffeine etc; do I answer 'yes'? - maybe, since I had this diagnosed by 
the NHS, or maybe 'no', if I think they are only talking about heart attacks 
etc).

My understanding of questionnaires functionally is that they act as a rough 
(self-)classification / triage instrument to save time and resources of 
expensive professionals and/or tests.

There is some structural commonality among questionnaires, which is clearly 
different from scores and scales. One of them is the simple need to represent 
the text of the question within the model (i.e. archetype or template), whereas 
this is not usually necessary in models of scores, since the coded name of the 
item (e.g. Apgar 'heart rate') is understood by every clinician.

Whether there are different types of questionnaires semantically or otherwise, 
I don't know.

Hi Heather,

the key difference is that the assessment scales have a scientific validation, 
leading to clinimetric data, often for populations, but e.g. Apgar and Barthell 
are also reliable for individual follow up measures.

a simple question, answer, even with some total score, does usually not have 
such evidence base. I agree that in the data / semantic code representation in 
a detailed clinical model it is not different.
