Excerpt:

"Modern healthcare has contributed to physician burnout. Over the past
30 years, medicine has evolved from a profession where a newly trained
doctor could hang a shingle and guarantee his or her future to a highly
competitive industry where financial stability and autonomy are less
certain.

A generation ago, doctors were accountable only to their patients.
Now we need to answer to insurance representatives and hospital
administrators, many of whom have no direct experience in healthcare
but hold power over budgets and reimbursements.

It's that lack of control that has frustrated many doctors and Annals
of Internal Medicine left them feeling pessimistic about the future of
healthcare.
