Not really. You'll find plenty of nice doctors and nurses but hospital administration is the same political jerkfest as anywhere else. Maybe worse because the "nice guy" doctors and nurses are less likely to fight back. Also the doctors and nurses who want to get things done learn pretty quick to stop being so "nice".
