The Effectiveness of Caring System for Uncontrolled Hypertension at Takhian Health Promoting Hospital, Kap Choeng District, Surin Province

Abstract

This quasi-experimental research aimed to evaluate the effectiveness of a care system for patients with uncontrolled hypertension at Takian Sub-district Health Promoting Hospital, Kap Choeng District, Surin Province. The sample consisted of 66 patients, divided into two groups: an experimental group and a control group, with 33 participants in each. Data collection was conducted from March 18 to June 17, 2024. The research instruments included a questionnaire, a pre-test and post-test, and a blood pressure recording form. These instruments were validated for content validity by three experts, yielding Cronbach’s alpha reliability coefficients of 0.83, 0.78, and 0.74, respectively. Data were analyzed using descriptive statistics, Chi-square test, Paired Sample t-test, and Independent t-test, with a confidence level of 95%. The results showed that most participants in both groups were female (72.70% in the experimental group and 60.72% in the control group). The majority of participants in the experimental group were aged 61–70 years (33.30%), whereas most in the control group were over 70 years old (48.50%). Most participants in the experimental group had a body mass index (BMI) of 25.00 to 29.90 kg/m² (33.30%), while those in the control group had a BMI of 18.50–22.90 kg/m² (30.30%).

            After implementing the new care system, the experimental group demonstrated a significant improvement in knowledge scores by an average of 12.5 points (95% CI: 10.2–14.8; p < 0.001), self-care behavior scores by 10.7 points (95% CI: 8.4–12.9; p < 0.001), and a reduction in systolic blood pressure (SBP) by 15.3 mmHg (95% CI: -18.7 to -11.9; p < 0.001) and diastolic blood pressure (DBP) by 9.6 mmHg (95% CI: -12.3 to -6.9; p < 0.001), compared with pre-intervention and the control group. Overall, 75.70% of patients achieved controlled blood pressure levels. Additionally, all participants (100%) in the experimental group reported high satisfaction with the new care system. These findings indicate that the newly developed care system was effective in improving knowledge, promoting self-care behaviors, and controlling blood pressure among patients with uncontrolled hypertension.
