We certainly use SPARQL endpoints for patient records in the Cleveland
Clinic's SemanticDB project:
http://www.w3.org/2001/sw/sweo/public/UseCases/ClevelandClinic/ 
However, at present the data is only heart and vascular related -- not a
patient's entire medical record -- and it is only used for research and
quality reporting -- not for real time patient care.

Kudos!  That's a big step in the right direction.

In my view, SOAP is the wrong direction.  It is just adds complexity and
contributes to "babelization":

I think you're on the right track with RDF, SPARQL and RESTful
interfaces, as my talk at last year's SemTech conference explains:
