Concepts

CHT Applications support health workers with activities in their community. Health workers are guided through tasks — such as screening for high-risk pregnancies or diagnosing and providing treatments for children — and get real-time indicators for progress towards their goals. These workflows are highly flexible and developed using a combination of JavaScript, JSON, and XForms.

The JavaScript and JSON portions allow for full control of tasks, targets, and contact profiles, as well as other application settings. Forms can live in many parts of the app including the Tasks, People, and Reports pages. The XForms portion:

• extends the ODK XForm notation
• is used to define forms
• allows CHWs to register new families and people
• allows CHWs to complete surveys, care guides, and decision support (e.g., when assessing a sick child, registering a new pregnancy for an antenatal care visit)
