Effects of Using Triple S-HRP on Perceived Susceptibility, Perceived Severity of Hypertensive Retinopathy and Self – Care Behaviors among Patients with Hypertension

Abstract

The quasi-experimental research aimed to compare the mean scores of perceived susceptibility, perceived severity, and self-care behaviors for controlling hypertensive retinopathy among hypertensive patients before and after launching the Triple S-HRP innovation between the experimental and control groups. The sample consisted of 122 hypertensive patients aged 35 years and older, both male and female, who receiving received services at the chronic disease clinic in Wat Bot Hospital, Phitsanulok province. Participants were commonly selected through a random by lottery sampling in accordance with to the inclusion criteria and were divided equally into two groups of 61 each in the control group and in the experimental group. The study underwent over two weeks, which rendered education sessions with the Triple S-HRP innovation and followed - up by phone calls. Data collection performed by an interview with questionnaires and data analyses relied on descriptive statistics, including percentage, mean, standard deviation, and frequency distribution. Differences in mean score tests were dependent on inferential statistics, specifically paired t-tests, with a significance level set at 0.05. The findings revealed that after applying the Triple S-HRP innovation, the experimental group achieved significantly higher mean scores in risk perception, severity perception, and self-care behaviors for controlling hypertensive retinopathy than that of both pre-intervention scores and of the control group, at a statistical significance level of 0.05. These results indicate that the Triple S-HRP innovation can serve as an effective educational tool to enhance knowledge on preventing hypertensive retinopathy, to help patients to increase awareness of the disease severity and of the potential risks of complications.
