I have looked into the WfMC materials, and the basic process flow descriptions are currently met with the HL7 v3 Care Plan. (This is not a point if HL7 can do, it is the point that it is possible to define the clinical process using a standard, I think it is transferable to OpenEHR archetype as well). The key here is the use of the following mood codes: definition will tell you wat according to best practice or evidence base should be done for a patient with problem x. (including monitoring of observations, tests, meds etc). The OpenEHR template specification that links archetypes could perhaps do similar things. intent mood helps the clinician to carry over from guideline into the care plan what is necessary for individual patient P. Thus the set of data required can be determined, and it can be justified why items are not carried from guideline to plan. (E.g. you do not female things for a male patient). Then if some professional wants to order a observation this can be done with request. e.g. the doctor askes the nurse to measure the blood pressure 4 times a day. In the Goal mood, the expected value can be set, e.g. the expected value of BP in a week should best be 130/90. the observatoin is carried out say 7 days 4 times a day leading to 7 x 4 = 28 observations in event mood. The statement collecter allows to trend this. The comparison of goal versus the event(s) trends, or the last value of day 7 allows to determine if the goal is met (conclusion being then the 29th observation). The derivation method allows to specify also workflow rules like: do BP measurements until 4 x < 130/90 or similar as a criterion for the do X until Y workflow standard. I am not telling this is best handled in HL7 v3, I just want to say that a] it is possible to express clinical meaningful workflows, that at EHR level are pretty handy for a nurse to pop up on the worklist every 6 hours, and that it is possible to exchange the semantics of such a workflow / careplan via a message. Yes, this is interesting stuff and needs a lot of work. William -------------- next part -------------- An HTML attachment was scrubbed...
