Example Of Confidentiality Statement On An Email Can A Doctor Be Impeached For Violating Doctor-patient Relationship Rules?

Can a doctor be impeached for violating doctor-patient relationship rules? - example of confidentiality statement on an email

Ok, so in my AP Gov class we do a show trial. A cookie is described a doctor, the injuries of women in the murder trial protocol. I have two questions:
In New York, is considered a breach of confidentiality when the doctor examines the details of an injury to another person, even if this person was in office when the doctor's diagnosis of the injury to the patient (eg, it was an implied consent and therefore does not care to talk to).
In the case of an injury, the doctor may be accused as a witness contrary to the law, although it takes only a financial penalty.

Bonus points for this proof even on the basis of the previously contradictory statements be charged if the statements do not diing contradictory. For example, the doctor said, he knows the difference between violence and accidents. In opposi-examination, the opposing attorney asked if he the difference between someone who could make the stairs and encountered someone falls down the stairs and said nothing. As a genral question and is specific, it seems that if there is no basis for the accusation, but I have no formal legal knowledge.
Any information of a lawyer and law student who knows the laws in New York would be useful.
Thank you!
