if you know the doctor's name send a letter or fax with your concerns; mentioning your relationship to this loved one. providing unsolicited information does not violate the law but discussing this information with someone other than the patient is a big no-no. this may help but going with the patient to their doctor's visit would be a way to bring up the subject (with the patient present of course).
