Not at my hospital. And not at a lot of other hospitals. For what you say to be true, there are an almost equal amount of hospitalists that exclusively work nights. Can it be true that 50% of hospitalists prefer to be nocturnists? I find that hard to believe.

"One of the downsides of working with nocturnists is the limited supply of physicians willing to work nights.
When Sanjiv Panwala, MD, was looking for work as a nocturnist three years ago, he says hospitalist groups were bending over backwards to accommodate him. More people are trying to get nocturnists, says Dr. Panwala, now one of two nocturnists at Providence St. Vincent Medical Center in Portland, Ore., but there just arent enough people willing to do it."

"Theres a reason Dr. Sabharwal spoke in the past tense, though. Although he was one of the first to document the nocturnist trend, in a first-person piece in The Hospitalist in 2005, his hospital has since given up on its nocturnist program.
The problem was recruitment. Even with a significant salary differential, there was no interest from anybody, Dr. Sabharwal said. He understands his colleagues reluctance, as his sleep schedule is still suffering the consequences of working as a nocturnist. I havent worked nights in a year and a half and Im still not back to normal. "
