This year, we published a peer-reviewed journal article in BMJ that outlines our thinking about digital systems for managing large-scale HEARTS programs. This implementer report explains how important user-centered design and hyper-efficient tools are to succeed at scale at controlling hypertension.

Implement a user-centred digital health information system to facilitate rapidly and substantially increasing the number of patients treated for hypertension in low/middle-income countries.


User-centred design of Simple, an offline-first app for mobile devices to record patient clinical visits and a web-based dashboard to monitor programme performance.


The Simple mobile application scaled rapidly over the past 4 years to reach more than 11 400 primary care facilities in four countries with over 3 million patients enrolled. Simple achieved median duration for new patient registration of 76 s (IQR 2 s) and follow-up visit entry of 13 s (IQR 1 s).


A fast, easy-to-use digital information system for hypertension programmes that accommodates healthcare worker time constraints by minimising data entry and focusing on key performance indicators can successfully reach scale in low-resource settings.

Simple is the fast, free app for clinicians to manage their patients with high blood pressure and diabetes.
