Telemedicine for blood pressure control in low- and middle-income countries: the journey ahead

Abstract

In just over a half-century since the initiation of telemedicine, technological developments have created multiple options to shape how patients can access healthcare and interact with healthcare providers to better prevent and manage hypertension. In several high-income countries, patients are connecting to their healthcare providers online to book appointments, request prescriptions, see test results and engage in pro-active health management. Mounting evidence suggests that telemedicine and mobile health (mHealth) services can yield greater reductions in blood pressure when compared with usual care while also offering greater reach, efficiency, and potential cost-saving. A deeper examination of implementing such systems at scale in high-income countries shows varying approaches and levels of success. While research investigating the benefits of technology for blood pressure control in low- and middle-income countries is growing, in regions such as sub-Saharan Africa, economic and digital divides present major challenges to scaling such technology. Substantial national investments in infrastructure and skills development are needed alongside consultation with multiple stakeholders to ensure that technological advancements do not further drive health disparities in the region.
