Health facility workers in Uganda report drug stock level and disease surveillance data using mTrac, an SMS and web-based data collection system. At the district level, health teams use the mTrac dashboard to review, verify and approve the data submitted. mTrac supports data-driven decisions by providing decision-makers with rapid insight on supply chain and other ecosystem components required to effectively deliver drugs and identify potential outbreaks. When mTrac users identify errors, they can send a free SMS to the reporting health worker with a request to review and correct the data. The dashboard also surfaces facilities that are failing to report data, making it possible to follow up in real-time. mTrac is built on the open source RapidPro software platform, a white label version of TextIt.
