I think the article is great at drawing attention to this issue. But, the article proposes things that won't fix the problem. The 80 hour work week has nothing to do with this. If the work hours are increased to 100/week, that will just be another 20 hours doing things other than spending time with patients.
The reality is that residents are income generators for the hospital. What generates revenue? Admissions with lengthy notes, imaging and lab tests, procedures, and rapid discharges. If you are an intern in medicine or surgery, your job generating revenue involves writing lengthy high level admission and progress notes, ordering and staying on top of imaging and lab tests, coordinating the consultants who do the procedures, and doing lengthy discharges (god forbid they get readmitted...).
The emphasis is on turning patients around as quickly as possible, so the job is to admit and discharge patients as quickly as possible. They often have chronic illnesses that don't need much actual history or physical exam work. Explaining things to patients or talking to them pays the hospital absolutely nothing. Nobody is going to tell you that you shouldn't take your time with patients directly, but they will call you slow and wonder why you spend too much time with patients if you do so. The reality is that as residents patients are scheduled or put on you too quickly for you to spend this sort of quality time regardless.
It's most time efficient not to ask patients questions, but have the note written before you even walk in the room. I was told as an intern that I should be aiming for level 5 consult notes every time, and that's what I did. So I would always get in and out of a room quickly and then write a note. With EMR, writing notes was supposed to be easier, but instead the notes are just lengthier, better written (better for malpractice in some ways), and generate higher billing. With EMR, the charting requirements just get higher, so while the efficiency for doing the same work improves, the bureaucracy increases with this efficiency so that there is no net gain. Not to mention all the headaches with the EMRs when they don't do what you want them to.
If you increase time in the hospital or bring in more residents, none of this will change. Spending more time in the hospital would simply mean being given more patient responsibilities that are the same (i.e. covering another service or more patients per resident). If there are more residents, that just means more services or patients can be covered.
The real way to fix the problem is to incentivize actually spending time with patients. It pays much better to see patients quickly than to see one patient for a long amount of time. It pays much better to write lengthy notes than short ones, regardless of how much time you actually spent with the patient. Residents allow attendings to see more patients and write better notes. This may translate to more time the attending spends with the patient or more time for the attending to do research. It may translate into better attending happiness and recruitment. But, the resident's primary job as a revenue generator by seeing patients quickly and writing lengthy notes is unaffected by anything proposed in that article.
