In re Anderson:
a.    Patient sued for sexual assault against a technician and sought discovery of the identity of other patients who had similar complaints against the technician.  Clinic refused to comply with discovery request, claiming it was physician-patient privilege.
b.    HELD: Although rules of civil procedure do not specifically mention that privilege, there is language that exempts any matters protected by privilege.  The patient-physician privilege goes beyond communication and reports and extends to patient identity.  The court said the information of patients’ identity is privilege and is not subject to disclosure.
c.    Doctor-patient relationship is from common law.  The medical practice act talks of the communication privilege between the physician and patient.
