... the Act inhibits physicians from communicating with their patients about issues which may become relevant to their patients' health and safety. It also inhibits physicians from making a reasonable, inoffensive notation in their patients' medical records, even though such notation would cause no legally recognized harm to the patient (or anyone else) and might protect the physician against a claim of medical malpractice. Any benefits that might be attributable to the Act, to the extent they may exist at all, are far outweighed by the burdens the Act imposes on the First Amendment rights of physicians and their patients.
