Starfleet Medical Ethics, and why I'd never use the EMH

In episode #130, "Pathfinder", Voyager is contacted through a new communications technology created by Lt. Reginald Barclay (better known as Howlin' Mad Murdock on the A-Team). At the end of the episode the crew toasts Lt. Barclay, and the captain asks if anybody knows him. The Doctor mentions that he read Barclay's file, and in a stunning lapse of professionalism, tells everyone about Barclay's amusing medical history (which includes phobias, addictions, and one time turning into a giant spider). Have his ethical subroutines just been corrupted, deleted, and rewritten so many times that after five and a half years they just don't even kick in anymore? Is his usual contribution to cocktail parties to tell everybody the 1st officer was a bedwetter?

I also assume that the file had a picture of the guy, so when the captain asked if anybody had a reference for the guy, you'd think that the Doctor would mention that in a sense they all sort of met him back in episode #10, "Projections", WHEN HIS HOLOGRAM TRIED TO STEAL THE SHIP. You'd think that would be something people would remember, the time Ferengi pirates sent a hologram from the alpha quadrant who charmed the whole crew before trying to murder them. It would also be a bit more appropriate than "Apparently he's sought extensive treatment for his crippling fear of transporters, what a freak." Granted, the Doctor's program had been rewritten or taken over by self-aware smart bombs and the like, and his holoemitter had been broken or embedded in the brain of a borg drone about 120 times in the intervening episodes, so maybe it's understandable he'd forget some things. Kind of makes you wonder what medical knowledge he's also forgotten though, doesn't it?

That being said, an indeterminate number of lightyears from Earth (the only explanation for their variable progress and the way people always catch up to them is if they went in the wrong direction most of the time) and if you get sick, your medical options are limited. You can go see the EMH whose medical ethics and long-term memory are intermittent, or you can see the other health care provider... an ex-con who was only halfway through his sentence for treason when he got pressed into service. I have to assume the replicators are working over time making vitamin C for a crew that's desperately afraid of going to sickbay.
