So the vast majority of doctors are condemned? That sounds like a very unfavorable environment for medical practitioners. I think its only natural to try and protect oneself.
From 2000 to 2004, in one of my country's states, 372 doctors were taken to court but only 23.9% were condemned¹. The number of lawsuits have been increasing ever since; I found a news article with more recent figures from another state but couldn't find the actual source of the numbers. It said 35% of verdicts were guilty.
