Thus, the Work Group decided upon a Weak for recommendation. More research is needed to evaluate intensity and duration of dietitian-led interventions to improve blood pressure control and effectiveness of registered dietitian-led nutritional intervention to manage HTN in specific subgroups (e.g., different ages, ethnicities). Recommendation 13. We suggest technology-based interventions (e.g., e-counseling, electronic transmission of data, telemonitoring, mobile applications) for improving control of hypertension. (Weak for | Reviewed, New-replaced) Discussion Several key words are defined to better understand this recommendation and its impact. Telehealth refers to data communicated between the patient and provider in ways other than face-to-face interactions. This is accomplished through a variety of methods to include use of computers, mobile devices, or mobile applications. In contrast, telemonitoring is the use of information and communication technologies to monitor and transmit items related to patient health status between geographically separated individuals, which permits home monitoring of patients to include nursing or residential care homes using external electronic devices. Methods may include e-counseling, real-time consults, electronic transmission of data and interventions, mobile interventions, and/or interactive digital interventions. Additionally, mHealth is defined as mobile health. The World Health Organization defines it as the use of mobile applications and wireless technology to support the achievement of health goals.[90] In the development of this recommendation, the Work Group considered whether concurrent treatment impacted outcomes. The Work Group considered whether the intervention of interest was provided instead of, or in addition to, usual care (in-person visits). Some of the possible interventions may include mobile applications, telehealth monitoring, telehealth visits with primary care or a subspecialty.
