If we decrease the 80 hour work week further, one of the following has to happen:
- We decide that less training is OK, and leave everything else alone.
- We increase the length of training to offset the decrease in hours.
- We switch to a true "competency" based system -- i.e. your training is as long as it needs to be. In order to do this, we would need some very reliable metric of competency, else it leaves PD's in a truly horrific role (for everyone).
- We average the hours out. In my program, there are busy months which tend to run 70-75hrs per week, and then there are Electives which are 7:30AM - 4-5PM no nights or weekends. If we were to switch to a 56 hour week, I'd probably have to move some additional work (i.e. weekend coverage) into the electives. I personally think this would be a tragedy.
- We hire more people. Not going to happen, Medicare can't afford it.
- We get "more efficient". Might happen in the long run.
I think the interesting question for debate (lost in some of the dialog above) is whether residents should work 24 hour shifts. We could switch to an 16 hour shift system that is still 80 hrs per week. Why should residents work 24 hours?
- Cool stuff happens at night, and residents are at the forefront of that "cool stuff"
- Residents get more autonomy at night, which is a good learning experience.
- Working night shifts means missing out on day activities -- conferences, etc.
- Working on a team (Resident/Interns/Medical student) taking call together is a huge bonding event. It gets lost in a shift based system. For example, on Internal Medicine rotations medical students usually admit a patient in the evening, then "digest" it, then present to the resident usually after 11PM once the team has capped. In a shift based system, this all gets rushed and you can't let the student go and learn at their own pace, since you need to get out at shift's end.
- A shift based system is inherently less "coverage efficient" than a call based system. In my calculations, you usually end up about 15% short in trying to fill all the shifts with the same people in an overnight call schedule.
Why shouldn't residents work 24 hour shifts?
- Many, many objective studies in various fields demonstrate that critical thinking skills, reaction times, and attention all deteriorate with both acute and chronic sleep deprivation.
- Whether or not this translates to poor patient outcomes remains unclear. If so, the effect will be small. Regardless, there are studies showing the chances of a post call resident being involved in an MVA are much higher post call, clearly a bad outcome.
- Some people think they can do fine post call. Honestly, I thought I was one of those people. Now, I am pretty sure it's not true, much like people who think they can drive "just fine" after having a few drinks. You just can't see it when you're the one "driving".
In a maximum 16 hour shift based system, residents will still work night shifts, so you would still get night exposure. In those surgical specialties where either 1) a certain procedure is very rare and you might miss it because of duty hours or 2) a procedure is so long that it would cause a violation, exceptions would be made. Presumably, both of these events are relatively rare.
Many of the above "pluses" of a 24 hour call based system can theoretically be designed into a shift based system, but there is an inherent risk that these good things will be lost, either through neglect, lack of resources, or competing priorities. Or, some may only be available in a 24 hour call system and really not work in a shift based system.
I am an IM PD so I really have no idea about running a surgical program. So, I have a question for Dr. Dre (or anyone who would like to chime in). Assuming that the hour limit stays at 80/week, could you realistically design your surgical residency to limit work to 16 hour shifts, or would that kill surgical training? Again, there could be rare exceptions for exceptional cases.
Good post. No need to reduce work load, lets just eliminate sleep deprivation. 16 hours sounds reasonable. 30 hours? not so much. BTW, dont worry about surgery residents, they seem to like their gig, and frankly I think they need to be excluded from the 80 hour limit too, so they can see more cases, which seems to be their major craving.
