Stumbled on to this hospital grading web site on another libertarian oriented blog. Here's the results for the hospitals within 50 miles of zip code 95501. For some reason that hospital in Fortuna is left out.
I suppose such things are nice to know, but I'm not sure I put that much value on ratings like this. If a certain hospital regularly got Fs, that might be cause for concern. I just seems to me, shit happens in hospitals and you can't always cover all the bases.
I spent some time last year in St. Joseph's. My personal annoyance with some things at St. Joes aside, it seemed a fine hospital to me.
