Medical malpractice pits the legal system's ethics of client advocacy against the medical profession's ethics of patient advocacy. Fear of liability may lead to defensive medicine, an aberration of both professions' intent.
Physicians have a duty to learn the facts and use their medical expertise to allay patients' fears rather than order unnecessary tests when a certain disease or condition receives a great deal of media coverage.
Presymptomatic genetic testing for neurodegenerative diseases can help patients make effective treatment decisions, but the medical profession needs to ensure that the increasing use of the tests is done responsibly.
Patients need to be aware that they are fully responsible for disclosing a complete medical history, and physicians may not be liable for damages if they do not comply.
