The Merced Sun Star has a good editorial on the difficulties California has had in weeding out bad doctors. We are not talking about doctors who make a mistake and commit medical malpractice. Good doctors can commit malpractice. The most skilled of us can make mistakes that cause harm. We are talking about doctors who should not be treating patients in the first place either because their skills are below what is required to comply with the standard of care or because they are unethical. California, in its defense, has unbelievable budgetary problems that certainly don’t help their efforts to restrain bad doctors. But you might also think that California doctors could do a better job of policing their own.
