At the back of a busy market is Tran, an underwear vendor. A doctor spotted Tran during outreach activities and offered her a free blood pressure check. Tran, who had undiagnosed hypertension, now has access to follow-up care and support to help manage the condition.

Digital health tools are a key element of the programme. Patient data is logged and tracked using a searchable database, enabling local health workers to quickly access a patient’s records and to provide follow-up support as needed. The system also features an optional SMS reminder service, allowing patients to receive messages – encouraging them to attend appointments, keep up with treatment and make healthy lifestyle changes – direct to their mobile phones.
