Health Tracker is an app for easily collecting and visualizing health information in rural and third-world areas. Health workers and hospitals can enter data via the Android app, and a Twilio-based incentivized SMS survey system encourages and reminds the patients themselves to input information, no matter what type of cell phone they have.

Ariadne Labs is concerned about the lack of collected information about newborn health. Though we know that many children die because of substandard health care, we are concerned that many more are dying without our knowledge. If we could gather this data, we'd know how best to treat the problem. Here's how Health Tracker works with Ariadne Labs' project:

  1. ASHAs (Indian health workers), social workers, and hospitals can use the Android app to input initial data about the births of new children.

  2. The women are then sent a small reward (diapers, call credits, etc.) for submitting their information. When the reward arrives, they are sent a short follow-up survey over SMS, checking on the health of their child. If they complete this survey, they receive another reward, and are soon sent another survey. This process continues until the child is no longer a newborn.

  3. The web tool visualizes the data sent in the form of pins on Google Maps. Pins are colored based on the health of the child: a pin is more red if the child is in danger, and green if the child is healthy. This way, help can be sent to those who need it most.

  4. Mothers can always text "alert" to the Health Tracker survey number, and a nearby ASHA will be dispatched to meet their needs.

Health Tracker was inspired by a number of the projects in the Hackathon. Though we settled on the Ariadne Project, our solution is flexible and scalable for a number of Health Tracking uses. For example, with only a few more lines of code, our solution could easily accomodate the "Yelp-like" app for submitting hospital reviews that was suggested. We hope that Health Tracker will change the way medical data is collected in the third world.
