Management of arterial hypertension: home blood pressure measurement is a cornerstone for telemonitoring and self-management

The development of mobile telephones has made it possible to design blood pressure (BP) monitors with data transmission via cellular lines, contributing to the emergence of “e-health”. Today, the direct-to-consumer marketing of devices create a new context allowing an algorithmic processing of information for remote decision-making either by the patient or by a healthcare professional. The home BP telemonitoring (HBPT) is the remote transmission of BP values, measured at home and transmitted to the doctor’s office or hospital, by means of telehealth strategies. In this context, randomized controlled trials (RCTs) studies have demonstrated HBPT ability in improving patients’ compliance and adherence to treatment and in accomplishing better hypertension control rates. The level of evidence for the drop in BP is “moderate” and the place of HBPT is not clearly established in current practice. Digital interventions have the potential to support patient in self-management. This approach presupposes the prior acquisition of skills, the level of which must be adapted to the level of health literacy of each patient. Few of medical applications (mobile apps or web-apps) for hypertension can be regarded as accurate and safe for clinical use and to date, we do not have high quality evidence to determine the overall effect of the use smartphone apps on BP control.
