I remember a previous study showing that junior doctors were actually associated with better results since they were more recently trained and had less ingrained habits/biases.
I would be surprised if it did. I believe the reduction in doctors’ overtime was a wash for parent safety as more shift handoffs and less sleep deprivation more or less canceled except in surgery where it increased mistakes.
I suppose what you want is someone with enough experience, but who hasn't been out of medical school for too long. Probably 7-10 years of experience would be the sweet spot.
I wonder if this applies to other domains as well.
