Role
I researched and synthesized literature in a short amount of time to produce an information visualization on the social determinants of health, leading to its installation and use at dozens of major health organizations and academic institutes.
I executed on all literature review and information visualization. I also designed its web presence and co-developed it with an engineer colleague.

Clinical care is the current focus of our healthcare system, but only accounts for 11% of our overall health outcomes.

We are more than our hospital visits and blood draws. Healthcare policy and services need to incorporate an individual's entire living situation and life experience to drive overall quality of health. All of these factors are the determinants of health.
Determinants of Health’s product goal was to communicate a research driven and visually engaging view of the factors that impact health.
Determinants of Health’s business goal was to disseminate the visual to the larger healthcare industry.
The resulting product should serve as a vehicle within health organizations to drive the concept that health is a holistic measurement of an individual’s entire life and experience.
The Determinants of Health visualization installed within the MITRE Corporation.
I first explored major health organization websites for information on the determinants but quickly found that a standard list of determinants did not exist. Surprised to find so much variability, I changed my focus to more academic literature. I wanted to get to the source to ensure that for all determinants I did include, they were as evidence-driven as possible.
I conducted a literature review of publications from 8 different major health organizations. 1-8
I documented these efforts by summarizing key points and patterns from each publication, which led me to the following insights:
With such variability in the primary sources, I decided to use the most developed model I found among the literature (Institute of Medicine 7) to inform much of the organizational structure and initial list of determinants.
To address the variability in the estimated correlation of each determinant category to health, the arithmetic mean of estimates from 6 different major health organizations were used (WHO, HHS, among others) 9-15
I created several sketches exploring how these could be represented. Based on informal feedback from several design and engineer colleagues, I found that a radiating circular representation appeared the most understandable for communicating the data.
There was high engagement in seeing the determinants in a web-like manner, which I noticed tended to prompt discussions on how the determinants connected and influenced each other.
This was one of the questions that surfaced again and again in this early phase from my viewers. For future iterations, I decided to include sources showing how quantitative and qualitative data on many of the determinants could be collected.
To ensure further content accuracy, I set up feedback meetings with 5 population health researchers and primary care clinicians by reaching out to several institutions including my alma mater, the University of Washington.
I designed the visualization to show major categories of health, but also for these categories to continually break into increasing granularity as the viewer moves to the outer circles of the visual.

To further push dissemination of the visual, I decided to open source the visualization online to further drive its use. It is licensed under Creative Commons Attribution v3, and available for download on GitHub. Detailed methodology and references are available at determinantsofhealth.org.
A comment I heard from several SMEs was “is there an interactive version of this?” There was a need for taking it to a level of personalized exploration that mapped additional information on top of the determinants.
For example, highlighting close connections across determinants to show level of correlations, or, slicing the view of the determinants based on preferences like viewing the determinants of lifespan, or the determinants of pediatrics.
By mapping the data elements of emerging standards such as FHIR and the Standard Health Record onto the determinants of health, the visualization can help lead future health services and data schemas towards a direction where health is not viewed merely through medical data, but through a combination of social, environmental, behavioral, genetic, and biological data.
