Clinical Application Value of Multimedia Education and Nursing Intervention in a Coronary Computed Tomography Angiography

Abstract

To explore the application value of multimedia education and nursing intervention in a coronary computed tomography angiography (CCTA). A total of 120 patients who underwent a 256-slice spiral CCTA examination in our hospital from April 2019 to April 2020 were selected. Patients were divided into two groups of 60 patients each, that is, the control group and the observation group, using a random number table method. The control group received traditional education before an examination, and patients were given routine breathing training. The observation group was given multimedia education and nursing intervention. The heart rate (HR), diastolic blood pressure (DBP), systolic blood pressure (SBP), and respiratory rate in the two groups were observed. The psychological status, imaging quality, and incidence of adverse reactions were compared between the two groups. The HR, DBP, SBP, and respiratory rate of the observation group were all lower compared to those in control group, and the differences were statistically significant ( p < 0.05). Following multimedia education and nursing intervention, the anxiety and depression scores of patients in the observation group were considerably lower compared with those in the control group, and the differences were statistically significant ( p < 0.05). Observation group image quality I level higher than the control group, and the proportion of patients with the difference was statistically significant ( p < 0.05). The proportion of grade II to IV patients was lower in the observation group than in the control group; however, the difference was not statistically significant ( p > 0.05). There was a significant difference in the incidence of adverse reactions between the two groups (χ2, p = .031). For patients undergoing a CCTA examination, multimedia education and nursing intervention can effectively improve their immediate psychological state, control their heart rate, and blood pressure before the examination, reduce the incidence of adverse reactions and improve imaging quality, thereby improving the overall reliability of a clinical diagnosis.

Effects of a 360° virtual counselling environment on patient anxiety and CCTA process time: A randomised controlled trial

“…121 This randomised trial provided novel information, as no previous studies on the effect of a 360 environment on anxiety among adult CCTA patients were found. The results demonstrate that access to the 360 VCE reduces CCTA patients' pre-CCTA levels of anxiety, which agreed with previous research on pre-CCTA multimedia education 11 and VR counselling. 51,52,106 However, it should be noted that earlier RCT studies 51,52,107 have focused on paediatric patients and used different scales; this makes any between-study comparisons difficult.…”

“…This minimises motion artefacts, improves image resolution and reduces the radiation dose. 88e90 However, anxiety during CCTA can reduce patient safety, 11 the quality of the imaging experience 44 the image quality, as well as increase the radiation dose. 10,13 Hence, focusing on the quality of counselling could prevent pre-cancellations and repeated scans.…”

“…Notably, 50e74% of patients experienced anxiety before the CCTA. 7,9 Pre-CCTA 11 multimedia education and enhanced counselling 10 were found to relieve anxiety and improve image quality. 11 Traditionally, counselling for medical imaging is provided in written format, which may be misunderstood and misinterpreted.…”

“…7,9 Pre-CCTA 11 multimedia education and enhanced counselling 10 were found to relieve anxiety and improve image quality. 11 Traditionally, counselling for medical imaging is provided in written format, which may be misunderstood and misinterpreted. 78,80,95e97 The use of digital technologies in counselling enables the simultaneous provision of written, verbal, and visual information, a feature which has been desired by patients.…”
