There was a survey conducted on 7,300 physicians, and nearly half experienced burn out, 38% had high emotional exhaustion scores, and 30% had high depersonalization score.

Why such a high incidence of  burn out?

First, the nature of the job;  it is a stressful job  watching over the health, life and death situation, nearly 60 hour work week for all, rotating duties, on call 24/7.

The others are bullying during the residency training, the pressure to pay back the tuition fee loans, and the threat of malpractice insurance.  The latter cause the escalation of costs of health care.
