Development and Evaluation of a Web - Based Application of Patients with Diabetes and Hypertension Using The New Normal Clinic Service Model: A Case Study in Sukhothai Province

Abstract

This study employed a developmental research approach with the objective of developing and evaluating a health information system to monitor and manage the care of patients with diabetes and hypertension in Sukhothai province, aiming to reduce missed appointments. The system was implemented through web services. The research process consisted of seven steps: 1) studying existing problems and the Health Data Center (HDC) system, 2) analyzing user requirements, 3) designing the information system, 4) developing a web application, 5) testing system efficiency, 6) evaluating the system, and 7) presenting the findings. The study involved 250 participants, including public health professionals and experts from the ministry of Public Health. Data were collected from 9^th January to 31^th March 2025, and analyzed using descriptive statistics.

The results showed that the developed system effectively linked patient data between hospitals, sub-district health promotion hospitals, and the provincial health office. Health service units could access patient data through web services and identify clinical risk levels at both individual and district network levels. This allowed the planning of care services according to risk categories and enabled follow-up of patients to improve disease control and reduce missed appointments. The system was reported to be fast, accurate, and up-to-date. The evaluation results indicated that the usability dimension had the highest mean score (X̅ = 4.83+0.45). All 127 health service units across nine districts (9 hospitals and 118 sub-district health promotion hospitals) fully adopted the system. Patient outcome tracking revealed that the number of diabetic patients with good disease control increased by 1,770 cases (10.29%) and hypertensive patients increased by 627 cases (0.88%). Additionally, missed appointments significantly decreased by 58.16% among diabetic patients and 31.94% among hypertensive patients.

In conclusion, the developed web application effectively enhanced disease control, reduced missed appointments, and strengthened data integration among health service units in Sukhothai province.
