Abstract—Telemedicine interventions are being
increasingly used in the care of adults with hypertension
however application of these technologies in children with
high BP has not been systematically studied. The goal of
this project was to develop a mobile BP telemanagement
system for children with hypertension and to evaluate its
feasibility. The prototype system consisted of a home unit,
decision support server, and care management site. The
home unit was based on a wireless netbook and
automated BP monitor. The home unit was designed to
complete a symptom diary, assess medication side effects,
obtain BP, undergo hypertension education, and
communicate with the decision support server. Feasibility
of the BP telemanagement system was assessed in 8
children ≤21 years of age with essential hypertension. The
study participants were asked to review the system
functionality and provide their feedback by completing
attitudinal survey and semi-structured qualitative
interview. Attitudinal survey results were as follows: 88%
reported that working with the computer was not
difficult; 100% reported that self-testing procedures were
not complicated; 75% felt the self-testing procedure took
little time and did not interfere with their usual activities;
63% felt safer while being monitored by the BP
telemanagement system; 63% felt it was important to
know that the self-testing results can be immediately
reviewed in the medical center; 88% would like to use the
home telemonitoring system in the future. Qualitative
interview results showed consistently positive comments
for content, interface and process components and
provided suggestions for improvements. We concluded
that BP telemanagement in children may be feasible
means for hypertension care delivery, and that further
development and evaluation of the system is warranted.

pressure [1]. The growing prevalence of hypertension in
children is alarming, as it is currently estimated to be between
3-5% among all children and adolescents [2]. Additionally,
there is significant concern that hypertension in childhood
may be associated with an increase in hypertension-related
morbidity and mortality in adults. Major barriers to successful
treatment of hypertension are patient non-adherence with
medication and the ability to maintain necessary clinic
follow-up appointments. The development of a successful
monitoring and treatment program for hypertension in
children is vitally important given the rising prevalence of
pediatric hypertension and concern for hypertension-related
morbidity and mortality in adulthood.
Several studies involving adult patients have explored the
possibilities of home telecare programs for patients with
hypertension [3-5]. However, none of these programs
included pediatric patients [6-8]. To date, there are limited
studies that evaluate the validity of blood pressure
self-monitoring and anti-hypertensive medication adherence
in a pediatric population using a home blood pressure
monitoring system. This is a critical population in which to do
such a study, given increase in prevalence of pediatric
hypertension and potential consequences of high BP in
children on future health during adulthood. We therefore
conducted a study to evaluate the feasibility of a new and
innovative multi-component telemanagement system as a
method of improving medication adherence and blood
pressure monitoring in children with hypertension.
Specifically, with this feasibility study, we sought out to
evaluate patient/caretaker acceptance of a telemanagement
system for blood pressure care in children, which involves
self-monitoring and allows prompt reciprocal exchange of
medication adherence and blood pressure measurement
information between patients and health care providers. This
system has not previously been implemented in a pediatric
population with hypertension and therefore is a novel
approach to improving monitoring and treatment of
hypertension in children.
II. SYSTEM DESIGN
Home Automated Telemanagement (HAT) is a
telemedicine system designed to assist health care
practitioners treat patients according to current clinical
guidelines, to assist patients in following individualized
self-care plans, to assist providers in monitoring patient
self-management, and to assist care management teams in
empowering and engaging patients in their self-care [9-12].
The HAT system is based on Wagner’s model of chronic
disease care [13] and supports patient self-management,
comprehensive patient-provider communication, and
multidisciplinary care coordination [14].
