The effect of an information brochure on patients undergoing cardiac catheterization on their anxiety, knowledge and fear: A randomized controlled study.

Abstract

Introduction Patients who undergo coronary angiography experience a rather stressful situation. They need information about this invasive procedure which most of the times find either from the internet, their referring physicians, acquaintances or friends with past experience of an invasive procedure. Aim The aim of the study was on the one hand to test the potential beneficial effects of an information brochure on undergoing a cardiac catheterization for the first time and on the other hand to highlight the importance of informing patients before coronary angiography and its beneficial effects on both reducing their fear and anxiety. Methods Patients were randomly assigned to an experimental group receiving the brochure at least 1 day before the cardiac catheterization (N = 44), or to a control group not receiving the brochure (N = 44). The SFQ, ISQ and STAI tools were distributed to both groups. Results All experimental subjects in the intervention group read the brochure. The intervention group had significantly lower scores on both short-term and overall fear compared to the control group. However, the fear of the long-term consequences of cardiac catheterization was similar in both groups. Women had higher fear of the short-term consequences of catheterization than men. The control group experienced a mean satisfaction score of 10.9 points (SD= 2.5 points) while the intervention group had a score of 11.1 points respectively (SD= 2.3 points). In addition, 95, 5% of the control group and 88, 6% of the intervention group patients considered that the provision of information could have been improved. In terms of stress, patients with co-morbidities scored 7.39 points higher, meaning they experienced more symptoms of permanent anxiety, compared to patients who did not have an underlying disease. In addition, the more the patients were satisfied with the information provided, the fewer the symptoms of transient anxiety they experienced. Conclusions Providing information in the form of a brochure regarding cardiac catheterization before the procedure, is of great importance and constitutes an efficient intervention.
