Before we derail this thread with this discussion. I'd like to know if you did your residency under the pre-work hours system or in the current system. Just so we can get a baseline of where we should begin the conversation. I would also ask you the counterpoint question, how are you so sure that things before were working well?
Sorry, have to put my $0.02 in. Got lucky (if one can call it that,) to put in time before and after 2003 when the first set of rules came in.
I did rotations before 2003 as a student. The big ones (surgery and medicine,) we had to work the hours of the interns (4am start, go until done (about 8pm or so.) Call was q3, and we worked (and operated,) on post-call days. There were no days that I wasn't in the hospital to at least round on either of those two rotations. Earliest I ever left the hospital on those "days off" was noon.
Supervision? Only if things really hit the fan. Chiefs were taking cases to the OR by themselves in some places, calling the attending after things were closed. Interns was trail by fire. Calling someone above you for help was a point of failure and ridicule. M&M was more a crucifixion of the resident than education.
I had to leave school for a bit for health reasons, and came back in 2004. There was definite improvement. Saw it most places where I went. There was still not complete above board reporting, but for the most part it was better. Still getting news here and there for hours violations, but for the most part things improved.
There was still a bit of "just do it" attitude, but there were some places that required you to be supervised in some things first (like lines, minor procedures, etc.) For the most part we started (with much inertia from the old hardcore types,) to encourage people to call for help not as a failure, but before failure happens (i.e. to call for help before things get bad.) No one goes to the OR without the attending even seeing them, and they are there from open to close.
I the change of mentality to call for help was the best change from the rules. It forced those who were indifferent to either start caring or get out of the business of teaching the new generation. I have encountered pockets of resistance, but for the most part, it is changing
I agree with you, DoctorDoom, that hubris, overconfidence, and indifference (from what I am reading from your prior post,) from the old-school are what killed people. Unfortunate that the only way to change this was from outside forces (blows the old quote "real change can only happen from within someone/a group," out of the water.) At a guess, these new rules address those that still think they can skip by rules by limiting the important, yet least trained group from being workhorses; the interns. Reports from a few of my current classmates (currently PGY-2,) demonstrated the rules are still being broken in their intern years (hours and level of supervision being the top two things.) I can see ACGME coming down on those programs like a pallet of bricks made of neutron star material if they see interns beyond 16 hours of duty/education time. The next step I suppose will be on-site surprise inspection to maintain enforcement.
I was very fortunate that surgery training site was very aggressive about ensuring hours were in compliance, and supervision and sign-offs for tasks were rigorous. My mentor (now the PD for that program,) would almost literally force us out of the hospital before limits were reached.
I'll admit that my view is a bit unique. But I hope it gives some insight into what has improved over the last decade or so.
