The report was not all doom and gloom for the medical profession. Those satisfied physicians were male, over age 45, and anesthesiologists, dermatologists, or pediatric or surgical subspecialists.

As for the least satisfied physicians, they were more likely to be female, younger than 45, and internists or family physicians. Others with a negative view were those in emergency medicine, critical care and radiology.

The type of practice made a big difference as well. Those doctors who own a practice, are locum tenens physicians, or are employees of a practice owned by a hospital or health system are more likely to be unhappy.
