This was interesting:

Burnout seemed to vary by specialty. Surgical professions such as neurosurgery had especially poor ratings of work-life balance and yet lower than average levels of burnout. Emergency physicians, on the other hand, had a better than average work-life balance but the highest burnout scores. The inconsistencies began to make sense when a team at the Mayo Clinic discovered that one of the strongest predictors of burnout was how much time an individual spent tied up doing computer documentation. Surgeons spend relatively little of their day in front of a computer. Emergency physicians spend a lot of it that way. As digitization spreads, nurses and other health-care professionals are feeling similar effects from being screen-bound.
