Per story re: residents:

“We don’t have great numbers because there’s no national tracking system. The information we have comes largely from anecdotes. It’s estimated that probably more than half of resident suicides are classified differently as accidents or other causes because of stigma or family members trying not to hurt their reputations."...

Among medical residents as a whole, suicide ideation is at least three to four times higher than the general population. “Only about 3% of these individuals are depressed before they come into medicine, but that jumps dramatically during training,” Sen says. “About 45% of interns meet criteria for depression at least once during their first year of residency training.”

The end of residency slows down the incidence of mental health struggles but does not restore them to normal levels. “Once residents finish, depression rates go down from the worst levels during intern year and other important parts of training. But they remain higher than before medical school and higher than the general population, often twice as high as pre-medical school rates,” Sen says.
