Key result
Smartwatch-based self-monitoring lowers mean arterial pressure by ~7 mmHg compared to standard care.
Why the study?
Hypertension is prevalent in older adults and often leads to cardiovascular complications when uncontrolled. The study evaluated whether smart devices combined with ontology technology improve hypertension-controlling behavior and mean arterial pressure.
Does a self-health monitoring program using smart devices and ontology technology improve hypertension-controlling behaviors and reduce mean arterial pressure in older adults with uncontrolled hypertension?
Does a self-health monitoring program using smart devices and ontology technology improve hypertension-controlling behaviors and reduce mean arterial pressure in older adults with uncontrolled hypertension?
Absolute Event Rate: 96.82% vs 104.16%
p-value: p=<0.001
Self-health monitoring with smart devices and ontology-based personalized feedback significantly reduced mean arterial pressure in older adults with uncontrolled hypertension compared to standard care.
May support smartwatch monitoring for hypertension in older adults; leaves open confirmation in randomized trials before practice change.
Background: Hypertension is a prevalent concern among older adults, often leading to complex cardiovascular complications when uncontrolled. Telenursing technology facilitates self-management, and the integration of domain-specific ontology allows real-time interpretation of behavioral and biometric data to provide personalized recommendations, enhancing patient engagement and self-care. Objective: This study aimed to examine the within-group and between-group effects of self-health monitoring using smart devices combined with ontology technology on hypertension-controlling behavior and mean arterial pressure among older adults with uncontrolled hypertension. Methods: The quasi-experimental design was conducted with 91 older adults in Bangkok, Thailand (46 experimental and 45 comparison participants). Participants in the experimental group used the "HT GeriCare@STOU" app on smartphones, linked to smartwatches for blood pressure monitoring, step count, and sleep pattern, with telenursing support via video calls. Data on hypertension-controlling behavior were collected using a validated questionnaire (Cronbach α=0.83; content validity index=0.98). Descriptive statistics and t tests were used to analyze within-group and between-group differences. Results: Within-group analysis revealed that experimental participants showed improved hypertension-controlling behavior and reduced mean arterial pressure after the program. Between-group comparisons indicated that mean arterial pressure in the experimental group was significantly lower than in the comparison group (P<.05), although hypertension-controlling behavior did not differ significantly between groups. Older adult participants and nurses reported high satisfaction, noting that real-time feedback increased awareness of blood pressure and motivated independent health behavior adjustments. Conclusions: Self-health monitoring using smart devices integrated with ontology technology effectively improved physiological outcomes and supported self-management in older adults with uncontrolled hypertension. The ontology framework enabled personalized, real-time decision support, highlighting its novelty, and potential to enhance nursing practice. Future studies with larger samples and longer follow-up are recommended to further evaluate the intervention's effectiveness and scalability.

Moolsart et al. (2025) studied Uncontrolled hypertension (n=91). Self-health monitoring using smartwatch and HT GeriCare@STOU mobile app with telenursing vs. Standard care was evaluated on Mean arterial pressure (MAP) at 12 weeks (p=<0.001). Self-health monitoring using a smartwatch and ontology-based app significantly reduced mean arterial pressure to 96.82 mm Hg compared to 104.16 mm Hg with standard care.
