A friend of mine is a surgeon at Kaiser, and I have the strong impression that they've gotten serious about making their system work. None of my co-workers who are on it have expressed complaints.
I pay the extra for an 'open access' plan, mainly so I can take my bigger problems (cancer, stroke & MS, so far) to Stanford Hospital (25 minutes from home or work). I figure that's where the most up-to-date folks are. FYI, UCSF is supposed to have a major MS center, too.
Best of luck,
RRMS dx 3/3/11; Copaxone since 12/1/11
