They're still required to consult us for ASA 3+ patients. We don't sign the chart. I'm sure some of them document "discussed plan with Dr PGG" but to be honest I don't think that's much of a liability. Even though Feres Doctrine doesn't apply to most of our patients (who are dependents and retirees, not active duty) we still have an extremely malpractice friendly environment to work in.
CRNA or no CRNA, supervision or no supervision, direction or no direction, our lawyers are the US Govt, on salary, with endless time and resources, and the US Govt will defend everything tooth and nail, even stuff that shouldn't (can't) be defended. Another nice detail is that military physicians can't be sued directly. The patient has to sue the government, and one of the downstream results (for better or worse) is that our names don't go to the national provider data bank after a payout unless a government inquiry (conducted by other military doctors) thinks we should. Unfortunately this means some military doctors who should be on that naughty list aren't, but it really cuts down on garbage "I was frivolously named; my carrier settled because it was cheaper than defending; now my name's on the list" incidents.
