Hypertension is currently one of the most common risk factors for the development of cardiovascular disease. An estimated 46% of the adult population in sub-Saharan Africa (SSA) has hypertension and its increasing prevalence is associated with factors such as urbanization and adverse lifestyle behavior. The process of managing hypertension in SSA includes increasing screening and diagnosis, and treatment of diagnosed patients. In addition to this process, community-based interventions have also highlighted promotion of educating healthcare providers and building capacity within the health system. Although there seems to be a process in place to control blood pressure of hypertensive individuals in SSA, optimal management of hypertension in this region remains a challenge, and the need for implementation of innovative strategies to achieve optimal BP control in hypertensive individuals remains critical.

Various hypertension guidelines recommend the use of out-of-office blood pressure monitoring as a technique to control hypertension. Thus far, several publications have highlighted the potential of implementing the use of home blood pressure telemonitoring (HTM) in general practice, globally. HTM is a telemedicine strategy that is implemented to remotely transmit blood pressure data and additional health information of patients from the comfort of their home to the health practitioner. To date, there is evidence from various controlled trials reporting that prolonged and regular use of HTM is associated with a significant reduction of blood pressure in hypertensive patients compared with usual care.

Despite HTM being reported as a potential measure for control of hypertension, there are no known estimates of hypertensive patients being managed using HTM in SSA and there have been few successful HTM programs implemented in SSA. HTM activity is reported in only 4 out of 46 countries in SSA using telephone calls, text messages and mobile phone health applications. In these HTM programs, significant reduction in blood pressure of patients was reported showing the great potential that HTM has in controlling blood pressure of hypertensive patients in SSA.
