White Coat Black Art eHealth

I saw Dr. Brian Goldman give a keynote address at eHealth 2011 in Toronto.  I missed getting a signed copy of his book - The Night Shift - but I took it out of the library later that week and enjoyed reading it.  His CBC radio program - White Coat Black Art -  is excellent.  I remember him saying at the conference that his pet peeve about ehealth technologies was too many usernames and passwords.  After all, he is an ER doctor, where every second counts, so having to remember dozens of usernames and passwords under time pressure, would be frustrating.  I don't know a solution off hand to that.  I know there is Open ID, but from my limited experience with hospital IT systems, and their privacy and security requirements, I can't see them using that.  There does have to be more privacy by design put into systems, for security reasons, but designers also need to think about patient safety - and I would argue that usernames and passwords is possibly an encumbrance to that in the ER.
