The TT Tracker: improving trachoma eye care using a mobile app

How does the TT Tracker work?

Patients’ data is collected when they first register for surgery, and then throughout their treatment journey. This includes their appointment on the day of their surgery and three follow-up appointments.

Based on the information collected, the TT Tracker sends online and email updates to staff, telling them which patients need to be followed up with and when. Even if different stages of a patient’s treatment journey happen in different locations with different medical teams, the surgeon in charge of their care has easy access to all the information they need through the app.

As well as supporting individual patients, the TT Tracker helps programmes understand how well surgeons are performing. And it gathers information on patient demographics, the number of patients and surgeries, the status of follow-up appointments and surgical outcomes, which is all updated daily and stored securely. Because the data is collected in a centralised system, country governments can use it to inform future work – most importantly, to support the goal of trachoma elimination.

We are using the TT Tracker in five countries and are working to bring its benefits to more parts of the world. Our goal is to roll out similar apps for surgeries that treat other widespread health conditions, such as hydrocele caused by the neglected tropical disease lymphatic filariasis, as well as cataracts. More in-depth resources on the app are available here.
