So Kaiser Permanente has Google/Doubleclick ad trackers on their site displaying my patient information

You think you’ve seen everything, but this one is pretty bad…

  • Kaiser is one of the largest healthcare organizations in the US (insurancer and provider).
  • I am a Kaiser member, so I use their website to communicate with my phyisician as they recommend.
  • Today, I log into their website, and read a message from my physician discussing some recent lab tests I had taken.
  • On that page, my ad blocker notifies me that it has blocked:
  • … and a few others that don’t have any business being on a website displaying health information either, like webtrends or some Adobe site. Even Truste is debatable.

Here is a screenshot of my ad blocker. Red is what the ad blocker blocked.

To verify, I looked at the HTML source, and it turns out that if my ad blocker hadn’t blocked it, the page would also include Doubleclick stuff! And some HTML comments which I will leave you to read … Here is the HTML, slightly reformatted to fit the space here:

<!-- Google Code for Member Log In -->
<!-- Google Code for Remarketing Tag -->
  See more information and instructions on how to setup the tag on:
<script type="text/javascript">/*
<![CDATA[ */var google_conversion_id = 881418786;
var google_conversion_label = "Ump9CM7hr3IQosSlpAM";
var google_custom_params = window.google_tag_params;
var google_remarketing_only = true;/* ]]> */</script>
<script type="text/javascript" src="//"></script><noscript>
<div style="display:inline;"><img height="1" width="1" style="border-style:none;" alt="" src="//"/></div>

“Re-Marketing” — are you serious?? On a page that has my health care data on it?

For reference, the URL for this page is!xxx (where xxx is something that looks like a session identifier which I have stripped).

P.S. I will append any Kaiser response to this post, should I receive any.

Response from Kaiser via Facebook:

The obvious question: Why on the page that displays confidential patient info? I’m not talking about your corporate home page here. So dear Kaiser, try again, this does not address the issue at all.
