The effect of using an application to provide information to patients preparing for coronary artery bypass grafting surgery (CABG-Coronary Artery Bypass Grafting) in the outpatient department of Vachira Phuket Hospital

Abstract

Background: Ischemic heart disease is a major cause of death worldwide. Coronary artery bypass grafting (CABG) is an effective treatment method that is recognized to increase survival and improve patient quality of life. However, preoperative preparation affects the success of treatment and reduces the risk of complications. Traditional patient information delivery methods, such as pamphlets or face-to-face teaching, may not be sufficient or have limited access to complete and continuous information. Therefore, the development of an application to provide information to CABG patients is an approach that can help patients have a better understanding of preoperative preparation.

Research objectives: (1) To study the effect of using an application to provide information to patients preparing for CABG surgery compared to using a pamphlet. (2) To assess the level of patients' knowledge about preoperative behaviors for CABG surgery. (3) To analyze the satisfaction of patients who received information via the application.

Research methodology: This study was quasi-experimental research using a two-group, pre-posttest design. The sample consisted of 50 patients preparing for CABG surgery at Vachira Phuket Hospital, divided into an experimental group (using the application) and a control group (using the pamphlet) of 25 patients. The research instruments consisted of an application for providing information on preoperative preparation, a patient knowledge questionnaire, and a satisfaction assessment form. The questionnaire was examined for content validity by 5 experts and the reliability of the patient knowledge questionnaire was Cronbach's alpha coefficient equal to 0.85. Data were analyzed using descriptive statistics and t-tests to compare the results between groups.

Results: Before the experiment, it was found that the knowledge level of the two groups of patients was not significantly different (p > 0.05). The experimental group had a mean knowledge before using the application (M = 10.44, SD = 4.55) and the control group (M = 10.12, SD = 3.33). However, after providing information, the experimental group had a significantly higher knowledge level at p < 0.05 with a mean (M = 16.32, SD = 1.93) while the control group had a mean (M = 13.04, SD = 3.91). This indicates that using the application helps patients gain better knowledge than using the traditional brochure. In addition, the satisfaction of patients who received information through the application was high, especially in terms of Ease of access to information and the ability to review information on demand.

Conclusion: The results of the study indicate that the use of an application to provide information on preparation for CABG surgery is more effective than using pamphlets in increasing patient knowledge and increasing patient satisfaction in receiving information. The implementation of the application in the outpatient department of Vachira Phuket Hospital may help reduce the workload of medical personnel and increase the efficiency in providing health education information to patients effectively.
