GDS & Medical Information

I recently received information from the Palo Alto Medical Foundation warning against use of the Google Desktop Search tool:

Do you use the Google Desktop Search tool or use a shared computer to view PAMFOnline?

Google recently released a new tool that allows people to scan computers for information in the same way they use Google to search the Internet. To enable the search, there is a setting that will index and cache Web pages including secure web pages like PAMFOnline. In other words, the tool has a photographic memory of what is on your computer.

How does this affect me? If this tool has been installed on a PC that you are using, it is possible for your private health information viewed through PAMFOnline to be cached on the computer’s hard drive and retrieved later by someone else.

The good news: Google Desktop Search is only able to retrieve Web pages that are viewed after it is installed. In other words, if you view PAMFOnline on a shared computer (e.g., Internet café, Library), someone cannot come along after you, install Google Desktop Search and pull up the pages you previously viewed.

A full copy of the warning is archived here.

This is pretty impressive – the risk presented by a new technology to personal patient health information was discovered, analyzed, and a solution distributed in a fairly short period of time. Makes me wonder: is PAMF unique amongst medical care providers due to its proximity to Silicon Valley? Or is this a sign of increasing sophistication of healthcare providers in light of HIPAA and other regulations designed to protect personally-identifiable information?
