Thanks, this makes sense to me and thanks for pointing out GLIF. I wasn't aware of that organisation. Let me check if I understand it: 1) in order to be able to compute a diagnoses against a guideline/ protocol (with the aid of a decison tree/ decision (support) system) the criteria of this guideline/ protocol should be stored in a format that is 'readable' by a rule based/execution engine (such as GLIF). So it becomes possible to compute that if symptoms A, B and C are present, that according to guideline X, diagnose Y is present. 2) In order to be able to establish the 'quality of a given diagnoses' the reference to the guideline(s)/protocol(s) used should be stored in the AT (preferably in the protocol section). So if guideline X is used by a qualified person to come to diagnosis Y, this could be re-usable information (for a person who adapted guideline X)), while if guideline Z was used one would like to do some additional testing (for a person who rejected or is unfamiliair with guideline Z) Is the assumption that, the GuidelineID in hte CARE_ENTRY class (that Sam mentioned) could be used to link (if wanted) the reference to the actual computable criteria, correct?
