Does anyone really think that people function as well when they have been up for 24-30 straight hours versus being well rested?
Items to consider:
1) Residents spend 35% of their time on activities with little or no educational value:

2) A primary reason that resident work hour restrictions have been opposed is financial IMHO:

Sadly, the answer to this appears to continue to be yes. And no amount of objective evidence will convince them. Consider this: Our air traffic system is the safest in the world and is arguably one of the safest mass transportation systems ever designed. Part of what makes it safe is limits on commercial pilots (FAR Part 135.267) which limits flight and duty times of air crew flying for hire. Why? Because in the 1930s we learned that well rested pilots make better in-flight decisions than exhausted pilots and accident rates went down.
Rules: Single Pilot: 8 hours Two Pilots: 10 hours
Rest: 10 hours between duty.
Exception exceeding 8/10 hour rule by < 30 min 11 hours rest
exceeding 8/10 hour rule by 31-60 min 12 hours rest
exceeding 8/10 hour rule by > 1 hour 16 hours rest.
The FAA wisely realized that it could extend the work day where there was redundancy and cross checking between pilots. A similar redundancy in medicine that keeps many errors from becoming manifest.
And the FAA knows, as do we in medicine, that occasionally stuff happens and schedules aren't kept. So these rules do not limit pilots to 8 or 10 hours in a given day. So, if a trip is legal for me to accept, I can fly and even if I end up flying 12 hours on a trip due to traffic/weather/mechanical/the catering truck is late, the FAA allows it. But there are consequences to the company: My mandatory crew rest time increases and that can play havoc with the next day's flight schedule. Companies have a strong financial/reputation incentive to keep the schedules honest.
What I do during rest time is my business, but at that point I am not company property. I can sleep, eat, pay bills or fly my own personal airplane for fun, but the company cannot make me work and the FAA will issue a "civil penalty" to me and my company if I do or they try.
Anecdote: NTSB Accident Report:
Pilot: 15000 hours total time, 2000 hours in aircraft make/model.
A/C: Beech B55 Baron
Weather: widespread low ceilings/visibilities, but all stations reporting above minimums at the origin of the trip.
Severity: 1 fatal, aircraft destroyed.
Events: Pilot went on duty at 1400 on a 7 leg Part 135 trip . His final leg was from DPA (Dupage County, Illinois) to DBQ (Dubuque, IA). The prior legs were uneventful. Prior to departure, at 0453 (local time) or after the pilot had been on duty more than 14 hours, the pilot obtained a weather update at DBQ which indicated the weather was well below minimums, and elected to depart DPA anyway. The aircraft crashed on approach to destination. Visibility at DBQ was ceiling 100 foot and 1/4 miles. The minimum ceiling was 800 or 900 feet and 1/2 mile visibility (I don't have the chart handy so this is a guess, but it'll be close to that.)
NTSB's investigation revealed no mechanical defect with the aircraft or its systems. Their conclusion as to the cause of the accident was pilot error due to poor preflight planning and lack of judgement as a direct and proximate result of fatigue. Contributing factors were pilot complacency. The flight was legal since all delays were due to weather related traffic congestion.
Some of you will say that aviation is apples to oranges, but apples are round, sweet and fruit. So are oranges.
The decision making cascades can be similar between the two and the consequences of a wrong decision just as devastating. (Those of you type-rated in something and have >1000 hours night/IMC logged, feel free to disagree). I know the pilot's quandary, I've done it myself once or twice. I survived and am here to tell about it. Would I do it again? I'd like to think not. But there are similarities between the occasionally grueling hours of flying freight and internship. The difference is that in medicine we only place one person at a time at risk, and not up to 300.
Some in medicine would have us believe that there is only one way to arrive at objective truth: a randomized controlled blinded prospective study. This is patent nonsense. It is true that such a study can arrive at an objective truth and test statistically the outcomes of two different courses of action
in a specific setting. They assert that absent that in exact circumstances, then the collective weight of information coupled with rational interpretation of same is merely opinion. I disagree. DrDre311gave his philosophy (based on an anecdote of 1) on the need for a good night's sleep. He/she is articulate, clearly very bright and has done well with relatively fewer hours of sleep. But, we will never know how much more of an achiever DrDre311 might have been if he had, in fact, had a full restorative nights sleep each and every night. Again, n=1.
Anecdotal evidence of 1 is just that. A story of a particular time and place. Gather a few anecdotes and pretty soon you may have a pattern of similar stories.
Over many years and thousands of anecdotes, all telling you the same or very similar things, and you have a preponderance of the evidence. And that is as close to generalized objective fact as we can get.
No one did a randomized identical twin study where one twin was raised in a tobacco free environment and the other in smoky bars and encouraged to start smoking at age 9. But eventually, smoking related illness anecdotes caused people to pay attention. RJR and PM were claiming as recently as the mid 1990s that there was no "objective evidence" that smoking causes cancer, copd and a myriad of other illnesses. But the weight of decades of anecdotal evidence led to the inevitable conclusion of the CDC that smoking is bad for you. I accept their conclusions. We do not need to set up a study that gets people killed to demonstrate this.
Likewise, I accept the conclusions of the FAA and the NTSB and the Air Force, at the same level as I accept the CDC's conclusion that smoking is bad for people's health. Sleep deprivation is very bad for you and those around you, based on decades of accumulated anecdotal evidence and now coupled with numerous studies.
To come to any other conclusion and discount the accumulated evidence before our eyes ( and this is my opinion) is sheer folly.
