Health care workers play a critical role in improving the diagnosis and treatment of high blood pressure. A new pilot study published in BMC Health Services Research evaluates a self-paced, case-based, mobile-optimized online training to diagnose and manage hypertension among health workers in Nigeria. On-demand mobile digital hypertension training effectively increases knowledge of hypertension management. It can also be a tool to build health workforce capacity through both initial and refresher trainings for hypertension and other chronic disease treatment.
