To allow others to make their own discoveries leveraging the same big data we used, I worked with a team to create ∆QTDb, an explorable database of the effects of drugs on the QT interval.
To create this resource I first analyzed and processed anonymized drug exposure and electrocardiogram data from our electronic health record. The resulting MySQL database contains each given patient's change in QT interval after exposure to one or more commonly prescribed drugs. I then implemented a web app using React.js and d3.js and an API to retrieve and visualize the relevant subset of data from the database.
We're currently preparing ∆QTDb for publication; in the meantime check out the site at www.deltaqt.org!
