You name it, it happens. After all, people are only human. A doctor's office is one of those places where trust and confidentiality combine implicitly, a place where people assume they will be safe. But it is in these small offices where the policies and procedures may not be regularly enforced. We're all friends.
Breaches happen based in expediency.
Co-workers share information quickly, rather than going through the long involved process. To make a long story short, one of the dental assistants accidentally stabbed himself with an instrument covered in my friend's blood, and pandemonium hit the office. When my friend walked into the waiting room, all the people sitting there knew his name, knew he was positive, and knew what had happened. Now that is an uncommonly nightmarish situation, but it shows the potential for confidentiality drama in a private doctor's office. The HIV Confidentiality Law is one of those attempts to achieve a just and civilized society through legislation.
