Abstract

Introduction
Coronary angiography and angioplasty is widely used in the diagnosis and treatment of coronary artery disease. Limited time to explain the procedure to patients in busy clinical settings may lead to increased adverse outcomes.

Purpose
To evaluate the effectiveness of a portable patient education video in improving knowledge and allaying patient"s anxiety prior to coronary angiography and angioplasty.

Methods
Consecutive patients undergoing coronary angiography and angioplasty were prospectively recruited over 1 year from June 2016 to May 2017 from a tertiary cardiac institution. We developed a 3 minute animated patient education video on the procedure. Patients were randomised 1:3 into a control group (receiving routine standard of care) and intervention group (watched video plus routine standard of care). Before the procedure, a self-administered written survey was conducted in the control group, pre-video in the intervention group, and post-video in the intervention group. Demographic data, knowledge and State Trait Anxiety Inventory (STAI) scores were gathered. Figure 1 shows excerpts of the video.

Results
We recruited 332 patients- 80 controls (80% males, mean age 59.6 ± 11.5, 51% previous procedures) and 252 intervention group (86% males, mean age 59.0 ± 9.4, 52% previous procedure). Compared to the control group, the intervention group had lower overall baseline knowledge scores (7.6vs8.5, p = 0.022) and similar anxiety scores (94vs92, p = 0.323); but significantly higher overall knowledge scores (10.3vs8.5, p= &lt;0.001) and lower anxiety scores (75vs92, p= &lt;0.001) after watching the video. Within the intervention group, there was a significant increase in overall knowledge scores (7.6vs10.3, p= &lt;0.001) and reduction in anxiety scores (94vs 75, p= &lt;0.001) before versus after watching the video. See Table 1. Subjectively, after watching the video, 98% of the patients reported benefit, 96% were more prepared and 85% less worried. There was significant improvement in knowledge scores and reduction in anxiety scores (p &lt; 0.001) in the subset of patients who had previously underwent a similar procedure (n = 131).

Conclusion
The video improved knowledge and reduced anxiety in patients undergoing coronary angiography and angioplasty. This is a useful adjunct to incorporate into existing workflows to improve patient care.
