M-health, a subsegment of e- health, is the use of mobile computing and communication technologies (eg, mobile phones, wearable sensors) for health services and information.212 Table B provides a list of examples of telehealth strategies and telehealth technologies. Importantly, these strategies include interventions beyond reminders for nonpharmacological or pharmacological intervention and increased awareness of BP measurement. They include active self-titration of medication and in- person coaching or e-coaching. M-health technologies are becoming more prevalent, and their use will continue to grow, consistent with recommendations from the Institute of Medicine.213 As new technologies emerge, including new devices for self-monitoring, it is unlikely that clinical trials will be repeated using each new technology. However, if self-monitoring is used, it is important to ensure that the BP measurement device used has been validated with an internationally accepted protocol and the results have been published in a peer-reviewed journal.214 Telehealth strategies that compare different frequencies of HBPM or ABPM have not been rigorously tested. Systems-level support, such as use of EHR (see SM-4), clinical decision support (ie, treatment algorithms), technology-based remote monitoring (see Table B), self-management support tools, and monitoring of performance, are likely to augment and intensify team-based care efforts to reduce HBP (see SM-7). Select telehealth strategies incorporate self-monitoring of BP. Among individuals with hypertension, self-monitoring of BP, without other interventions, has shown limited evidence for treatment-related BP reduction and achievement of BP control.50,211,215 However, with the increased recognition of inconsistencies between office and out-of-office BPs and closer correlation of out-of-office BPs versus office BPs with cardiovascular outcomes,216 and with greater reductions in BP being recommended for hypertension control, increased attention is being paid to out-of-office BP readings. Thus, telehealth, m-health, and e-health strategies will likely increasingly incorporate self-monitoring, as well.
