Learning Objective #1: - Analyze patient’s experiences of level of anxiety and well-being in a designed sound environment in the cath lab, a transcultural collaborative study.
Learning Objective #2: - Identify the effects of a designed sound environment and sound sources on patient’s experience of level of anxiety, a transcultural collaborative study.
Title: Designed Music Environment in the Cardiac Catherization Laboratory- the Perceived Effects of Various Sound Delivery Systems Overall Purpose:  To compare patient’s subjective experience of no music, a room music sound system, and a patient focused music sound system (audio pillow). Conceptual framework: A designed sound environment with the use of specially designed music is beneficial for cardiac catheterization patients in reducing anxiety and improving well-being. Methodology: This is a randomized, controlled study in Seattle USA and compared to the study results in Denmark. Each site randomizes 99 patients into 3 groups: no music, speaker music, and sound pillow music. The music sound environment consists of special composed music (Niels Eje, Denmark). Patients’ perceived response is measured by a five graded Lickert Scale, and perceived anxiety by a ten graded Lickert Scale. Nonparametric methods were used. Mann-Whitney test was used to compare groups. The Spearman rank correlation was used to compare the association of variables, and the Friedmann test as modified by Conover was used for pair wise comparison if an overall difference was found. A 5% level (two-tailed) of statistical significance was used. Conclusion: Music intervention influenced positively the patient’s experience of well-being during the stay at the cath lab. Music intervention reduced the anxiety level of the patients by approximately 50% over the control group, a statistical significant difference between the three groups of p <0.01. Overall conclusion: Music intervention with special composed music reduces anxiety and improves well-being during cath lab procedures. Audio pillows proved superior to ceiling suspended loudspeakers with respect to anxiety reduction. Discussion: Patient’s perceptions of increased well-being and reduced anxiety support changes in current practice. 2
