Self-health Monitoring by Smart Devices and Ontology Technology for Older Adults with Uncontrolled Hypertension: Quasi-Experimental Studies
ABSTRACT
Background:
Hypertension is a prevalent concern among older adults, and when left uncontrolled, it can lead to complex cardiovascular complications. Tele-nursing technology facilitates self-management, empowering older adults with uncontrolled hypertension to regulate their behaviors and achieve sustainable disease control.
Objective:
This study aimed to study the effects of self-health monitoring using smart devices and ontology technology on disease-controlling behavior and mean arterial pressure of older adults with uncontrolled hypertension.
Methods:
The design was quasi-experimental research. The sample was older adults with uncontrolled hypertension who lived in Bangkok, Thailand, which was divided into 46 experimental people and 45 control people. The implementation tools were a program of self-health monitoring using smart devices and ontology technology. It featured the "HT GeriCare@STOU" application on smartphones that was linked to detecting blood pressure from smartwatches, and telenursing could be provided through the application and video calls. The data-collecting questionnaires had a Cronbach's alpha coefficient of 0.83 and a content validity index of 0.98 for disease-controlling behavior. Descriptive and t-test statistics analyzed the data.
Results:
The results revealed that after joining the program, the disease-controlling behavior of older adults with uncontrolled hypertension was better than before joining the program, but was not better than the comparison group at P<.05. However, the mean arterial pressure of older adults with uncontrolled hypertension was lower than before joining the program and lower than the comparison group at P<.05.
Conclusions:
A program of self-health monitoring using smart devices and ontology technology was effective for older adults with uncontrolled hypertension. The technological and cost problems are potential obstacles to eHealth programs. More experimental and longitudinal studies with larger sample sizes are needed to properly evaluate this program.
