What many people may not realize about the medical field is that the days of extremely long shifts are basically over. When we say "extremely long," we're talking about 36-hour shifts. These used to be very common, and most medical professionals expected these shifts, and had to prepare for them by resting up prior to -- or even resting during -- the shift.
These extreme conditions have given way to shifts that usually end after 14 hours. That's still a long day, but it's much more manageable. And as a potential patient, you're probably happy to hear this. After all, shorter shifts would seem to imply that medical professionals are better rested, more alert and, thus, more able to perform their job.
