Computable Declarative Representation of Clinical Assessment Scales in EHRs

Mercedes Arguello Casteleiro, Nicolas Matentzoglu, Bijan Parsia, Sebastian Brandt
2014 2014 IEEE 27th International Symposium on Computer-Based Medical Systems  
Clinical assessment scales, such as the Glasgow coma scale, are a core part of Electronic Health Records (EHRs).  ...  To solve this problem, we propose to separate the representation of the structure and content of an assessment scale from its enactment with the former being captured in OWL 2 and the latter being determined  ...  Figure 3 isolates the computation of the scale from the representation of the scale.  ...
