Abstract

This research and development study aimed to 1) create an innovative blood pressure control application, HTCare 2) compare blood pressure levels before and after using the innovation, and 3) assess satisfaction with the use of the innovation., using the software development life cycle framework and the Health Belief Model. The study framework was based on the Software Development Life Cycle and the Health Belief Model. The sample consisted of hypertensive patients with uncontrolled blood pressure who received services at Rakai Sub-district Health Promoting Hospital in fiscal year 2024 and met the inclusion criteria. The sample was selected by randomly sampling from the daily service queue numbers until a total of 30 participants were obtained. The research tools included the HT Care Application, an application effectiveness evaluation form, a personal information questionnaire, and a satisfaction assessment form for using the HT Care Application. Data were analyzed using descriptive statistics and paired dependent sample t-test statistics.

The research found that the HT Care Application had high effectiveness (M=4.38, SD=0.62), and the overall satisfaction score of the sample group was at the highest level (M=4.57, SD=0.52). The mean systolic blood pressure of the sample group before and after using the innovation was 137.70 mmHg (SD=10.64) and 126.57 mmHg (SD=5.29), respectively. The mean diastolic blood pressure before and after using the innovation was 85.60 mmHg (SD=9.41) and 82.57 mmHg (SD=4.63), respectively. Furthermore, the mean systolic blood pressure of the sample group significantly decreased after using the innovation compared with before using the innovation (p=.000), while the mean diastolic blood pressure of the sample group after using the innovation decreased compared to before using the innovation, but this was not statistically significant (p=.112).

Recommendation: Dissemination to patients with hypertension in the community or to individuals interested in using the HT Care Application to promote self-care at home to control their blood pressure levels within normal ranges. This may encourage behavioral changes in patients to reduce the risk of dangerous complications.
