Say a provider has a tricky case with an unusual constellation of symptoms. Most resources I've looked at (like MD Consult, for instance) seem to allow just searching on one symptom and return results for different possible diagnoses for that one symptom. What I'm looking for is something that will allow entry of multiple search terms and a cross-matching of results. I'm guessing there has to be something out there that does this, but I've not been in the profession long enough to have heard about it. If I'm missing something obvious, don't hesitate to point that out! Many thanks, Paul -------------------- Paul Howard, MLIS Health Sciences Librarian Salem Hospital phone: 503-561-5377 fax: 503-561-4777 [log in to unmask]
