The Dossia Health Risk Assessment

Powered by BioSignia™

Dossia has partnered with and integrated BioSignia™’s Know Your Number® (KYN) Health Risk Assessment into the Dossia Health Management System™. The Health Risk Assessment (HRA) is able to read a member’s health data from their Dossia PHR to auto-populate the appropriate data points of the KYN questionnaire with their professionally sourced clinical, biometric and personal information, allowing a user to more easily and accurately complete the assessment.

Know Your Number ® (KYN)

KYN is a reliable and scientifically validated HRA that has been used in employer wellness for over ten (10) years. KYN is set apart from conventional HRAs given its advanced disease specific morbidity models “synthesized” from disparate evidence-based information and continuously updated with new discoveries. This methodology produces an “evergreen” opportunity to create prediction models for various morbidities.

The Advantages

Using morbidity-based models that measure individualized disease risks result in the following advantages:

  • More targeted identification and education of one’s unique modifiable risk factors
  • Quantification of new and future disease burden (cost of care) for all stakeholders
  • Identification of avoidable future disease cases within a specific population, as well the as associated costs and outcomes at the aggregate reporting level for employer wellness initiatives

Know Your Number currently has models for the following diseases: heart disease and stroke, type-2 diabetes, heart failure, COPD, lung, breast and colon cancer, as well as second heart attack, and obesity.

KYN’s Synthesis Analysis™ Modeling methodology has been validated against the National Health and Nutrition Examination Survey (NHANES I) Epidemiologic Followup Study (NHEFS) data and on a theoretical basis by an investigator at Duke University. Both of these validations were published in 2005.

KYN is not dependent on data feeds from the Dossia Health Record. Data may be manually entered by either the user or a health professional surrogate

Health Risk Assesment Questionaire

The Dossia Health Risk Assessment, powered by Biosignia, consists of 40-45 questions. The variability is due to questions pertaining to smoking status and female specific points of data (i.e. past pregnancy).

  • Start a new HRA or go back to one you have either already completed or started but haven’t finished.
  • There is no limit to the number of times an individual may take the HRA.

As mentioned previously, the Dossia Health Management System™ is able to, with the user's consent, prepopulate the appropriate lines of the HRA with the health information from a user’s Dossia PHR. Self reported data is accepted as well.

  • Progress bar allows for users to gauge their progress as they go through the HRA
  • Key on right lets users know what section they are working on

Dossia has made sure this HRA is visually appealing for the user and quick and easy to complete. This keeps users engaged; once initiated this HRA has a 98% completion rate.

Final Report

Users will receive a Final Report once they have completed the Health Risk Assessment. From here participants will also receive a more extensive Final Report that will provide them in greater detail their results and what they mean.

  • Participants will receive their results in automatic real-time electronic delivery to the user’s record on the Dossia system.


After completing the Health Risk Assessment all users will receive a final report that will ultimately provide them with a meaningful understanding of what their current health status is, as well as empower every participant with the knowledge and motivation to make better, more healthful decisions to improve their health and extend their life.

The analysis of the data is conducted using a patented statistical technique that evaluates each of risk factor that users present, as it relates to disease onset based on the results of over 200 scientific studies.

The results of that analysis are outlined throughout an 11 page report. Specifically, this report addresses:

  • The risk of having major chronic disease within the next five years
  • How much of the disease risk is in the user’s power to control
  • And lastly, suggestions for positive changes the user can make to live a healthier life
