Ogbuji, Chimezie wrote: Dan, I've very familiar with the SOAP model. The primary motivation for my questions about assessment had more to do with distinguishing an action from data that is derived from it. This speaks directly to the problem of the 'anti-pattern' where ontologies for medical records are built *directly* from models that were designed with data-level concerns in mind and thus semantically inconsistent (so called "information models"). The sense of assessment as used in this paper suggests that an assessment is data (and thus appropriate to consider a diagnosis), but consider that there are other senses of the word and one in particular is "the act of judging or assessing a person or situation or event". In the latter case, an assessment refers to the act. I was simply trying to tease out which of these Tom had in mind. <danR> It is true that in traditional lab department systems, the 'data from the assessment' was modeled separately from the 'assessment action.' This is not exactly "wrong." However, it was noted that one cannot deliver a "numeric result" without restating the action that generated the result, e.g. serum WBC is the action and serum WBC of 10,000 WBcells/ml is the result. In physical sciences, it is considered good practice to always include the methodology of the action when describing the data. Accordingly, it is best practice in the science of healthcare to also report on the nature of the action itself at the same time as reporting on the data derived from the action. [VK] It may be the case that one can model key properties that can enable the accurate assessment of the action. For instance, one could model things like the property being assessed, who is doing the assessment, the qualifiers of the assessment, etc. The CEM approack followed by IHC seems to adopt this strategy. From what I can see, there doesn't appear a need to model all the aspects of an action. On the other hand, if there is indeed a need for more contextual information related to the action of performing the assessment, it is probably a good idea to model these two things separately and then link them via approporiate relationships modeling the context, but this likely to happen in an application specific manner.
