I received an email, supposedly from my hospital, asking me to complete a patient satisfaction survey. Normally, this hospital mails paper surveys, or does them on their own web site. When I clicked on the link, the first thing asked for was my date of birth, to "personalize my user experience". I noticed the site showed an orange rating from WOT, so I did not complete the survey and unsubscribed from future surveys. Too many places are trying to obtain personal information, which I only share with my medical providers. Sorry, Press Ganey.
