Privacy Statement


CHADIS is a tool that collects and stores information about patients, seen by physicians, with the goal to improve health care. This information may be personally-identifiable information tied to patients and respondents, e.g., parents and teachers, as well as their responses to various questionnaires. This information is stored indefinitely within CHADIS, and is required in order to provide our services to your doctor, and will not be shared with anyone other than your doctor. Aggregate reports (those that include information about hundreds of patients, but do not identify anyone in particular) are routinely used to improve CHADIS and may be shared with outside groups. Your personally-identifiable information will never be shared with anyone outside CHADIS.

Aside from health information, CHADIS also stores information about your use of CHADIS, including the Internet address from which you used CHADIS, the type of web browser you are using, the time and date of use, the address of the page that took you to CHADIS, and any cookies sent by your web browser. This information is used to measure the use and performance of CHADIS, and to help improve CHADIS for all our users. This information will not be shared with anyone outside CHADIS.

Cookies are used to track your use of CHADIS during a single visit to our web site. CHADIS works without cookies enabled, so if you are uncomfortable with their use, you are free to disable them while using CHADIS.

If you send an email message to someone at CHADIS, we will keep a copy of your message indefinitely so that we can respond to it and refer to it in the future if necessary. This information will not be shared with anyone outside CHADIS.

Security Statement

CHADIS maintains the highest security standards to help protect your data. Data being sent to or from CHADIS is encrypted at the highest level supported by your web browser using HTTPS. We currently only accept connections which are encrypted using 128-bits or better and using TLSv1 or better. Our servers are kept in locked cabinets in a data center which requires a smart-card and hand-scan to gain access. Data backups are encrypted and stored in a secure off-site location.

Supporter Testimonials

“Dr. Lindgren’s patients access a cool web tool, called CHADIS, that allows them to help him screen for all kinds of conditions including developmental delays, behavioral issues, or even learning problems.  You see, this doc is big into prevention. But it’s hard to get the info he needs in a regular office visit since parents often have their hands full with a sick child.  Now his patients can be way ahead of the game and parents love it.”


Dr. Carl Lindgren
Healthy Futures Pediatrics

CHADIS has been a really great resource for my practice. With CHADIS, I have access to a comprehensive list of screening and assessment tools. I can use the tools to accomplish multiple goals, including early screening and intervention. As a physician, I know that early intervention DOES WORK!

Treehouse Pediatrics has used Chadis as a part of its day to day operations for the past couple of years. We have found it to be a tremendous asset in our operational efficiencies.  Parents appreciate the convenience of completing their child’s developmental, ADHD, and asthma questionnaires at home, and it has proven to help make all of our visits requiring questionnaires run more smoothly.  Furthermore, we appreciate the interpretation and documentation that Chadis provides for these questionnaires. We feel that Chadis has become an integral part of our operational efficiencies.  We do not know what we would do without it.
