That statement needs to be qualified, because it is not an exceptionless truth. There are situations in which the government is justified in examining medical records. What you have to argue in this case is that the harm done by the government's intrusion into these doctors' records is greater than the harm that is now being done and will be done to partially-born children if not examining these records ensures that the PBA ban will be overturned. That would not be an easy argument.
No. The patient's name is not being given and the parient is not in legal jeopardy whatsoever. THe docs are making claims that are based on the records and the court should have them, because those records are the evidence the claims are based on.
Otherwise their is no justification for obtaining med records at all, because of the 5th amend. The greater harm nonsense is just that, nonsense.
