Why do the overnight shift of nurses take vital signs every four hours? So they catch rapid unexpected changes in patient conditions more quickly. Put more crudely, so they don't accidentally leave a corpse in a bed for the next shift. Having to write, or type, the patient's blood pressure into a log is a way to help the overnight nursing shift remember to pay detailed attention to each patient, at least for a few moments. If their instructions were "stop at each door and listen for the patient breathing" those nurses might well miss important changes.
Hospital care these days is not only about the towering figure of the heroic superhuman doctor, Harvard Medical School lore to the contrary notwithstanding. It's about all the folks who look after patients, from the community primary care doctor to the RN, to the chaplain, to the "hospitalist" physician, to the person who cleans up, to the person who maintains all the electronic gear. The challenge is getting all these people to cooperate with the patient and for the patient's benefit.
The superhuman healer approach to medicine demands superhuman people to be doctors. They aren't, any more than the rest of us are. They have to sleep, and to eat, and to see many patients. So, a good hospital needs to be organized like a good company: where each person's skills and passion complement the others, and gets an extraordinary result from a collection of ordinary people. The buzzword for that is "synergy." Good discipline--good and predictable process--is part of synergy.
And, at the end of all that excellent care on our behalf, each and every one of us will become a corpse. A nineteen-year-old with a broken leg can be cured. A 90-year-old with cancer and pneumonia, not so much. It doesn't matter how towering a figure the doctor is, or how kind the nurse is.
A radical move in medicine would be to come to terms with death as a natural part of life rather than as a failure of the system.
