Effectiveness of nurse-led video interventions on anxiety in patients having percutaneous coronary intervention.

Abstract

Managing anxiety is essential to control anxiety-related complications. This study aimed to evaluate the effectiveness of a nurse-led video-based educational intervention on anxiety levels among patients undergoing a percutaneous coronary intervention. A pre-test, post-test quasi-experimental design was used. Between June 2015 and July 2016, 99 participants were allocated to comparison versus intervention groups, and a video-based educational intervention about the percutaneous coronary intervention was provided to the intervention group. The State Anxiety Inventory was used to measure anxiety levels at baseline, 2hours before, and 4 to 6hours after a percutaneous coronary intervention. After providing the video-based intervention, at 2hours before the procedure, results showed a statistically significant difference in anxiety mean scores (33.08 versus 60.88) between the intervention and comparison groups, respectively (P<0.001). At 4 to 6hours after the procedure, the anxiety mean score for the intervention group (M=24.1) was statistically significantly lower than that of the comparison group (M=44.17; P<0.001). A pre-procedure nurse-led educational intervention provided by video had a significant effect on reducing anxiety levels among patients undergoing percutaneous coronary intervention. Patients in the intervention group experienced a steady and consistent trend of anxiety reduction pre-cutaneous and post-percutaneous coronary intervention.
