At the Intersection of Big Data and Healthcare:
What 7.2 Million Medical Records Can Tell Us

They’re calling this extensive disease network the “Health InfoScape.”

When you have heartburn, do you also feel nauseous? Or if you’re experiencing insomnia, do you tend to put on a few pounds, or more? By combing through 7.2 million of our electronic medical records, we have created a disease network to help illustrate relationships between various conditions and how common those connections are…

 

We often have a tendency to think of illness as an isolated event, but our first analysis details the numerous (sometimes unexpected) associations that exist around any given condition. This gives us new insight as to how closely connected some seemingly un-related health conditions might be. Such results force us to re-examine conventional categories of disease classification, as the boundaries between traditional disease categories are thoroughly blurred.

 

Our initial results are a mix of the expected and the unexpected — simultaneously challenging and reaffirming our preconceptions of health pattern, within individuals and across the U.S.

And there’s yet more opportunity for researchers here:

Now that we have a succinct picture of the human health network in the country, we will continue our investigation by delving deeper into how the environments around us factor into these results.

The Health InfoScape constitutes a perfect example of the role of Big Data science and engineering into the future.
