At the end of an appointment , a resident wrote the patient 's follow up information on the clinic listing and gave it to the patient to turn in to the clerk . This should have been written on the patient 's router . The patient walked down the hall with the paper and handed it to the clerk . The patient did not seem to realize what he was carrying but the clerk did not comment on the error or draw attention to it . The list contained the name , appointment time , location , phone number and full SSN of one other patient . ;
