Hi Sam, We have tried, but it is not possible to represent a proper VAS scale in the archetype editor.
What clinicians want is exactly as I said before: being able to score a 5, 7, 10 for pain. This looks like the above instrument in this picture. But as you can see in some instance the patient will say, my pain today is like a 7.3 or a 3.6 or a 9.9 The qualified Real does not deal with it. So it appears not possible to handle the ISO 21090 PQ datatype which would allow to have a decimal. Further the qualified real does not allow to set the minimum 0 and maximum 10 score. If we apply the valid and reliable McGrath for pediatrics, we see the five level faces, where 5 is obvious the :-( sign (much pain) and the 1 is :-) (no pain) This would really be an ordinal, but stored with a number. For this one the qualified real would do. So we do experience difficulties in using the archetype editor to proper represent clinical and scientific knowledge. Hope you can find a solution for this.
