Effectiveness of educational videos on patient's preparation for diagnostic procedures: Systematic review and Meta-Analysis.

Although diagnostic procedures are crucial for secondary prevention and patient disease control, they often trigger fear and anxiety. These reactions highlight the need to adopt effective interventions to improve patients' experience and satisfaction. Recently, educational videos have been employed in preparing diagnostic procedures; however, there is no integrated understanding of their effects. This systematic review and -analysis aimed to assess the effectiveness of educational videos on patients' anxiety and satisfaction regarding preparation for diagnostic procedures. Three scientific databases (PubMed; Web of Science, Scopus), were used in this systematic review. Studies about educational videos as a form of preparation for patients undergoing diagnostic procedures published between 2000 and 2021 were included. A -analysis was also conducted. Sixteen studies met the inclusion criteria for systematic review, and seven were included in the -analysis. Nine studies of the total sample were about vascular procedures and seven studies about other medical image procedures. Of the fourteen studies that evaluated the use of educational videos on patients' anxiety, nine proved to reduce it significantly. Of the thirteen studies that evaluated satisfaction, seven showed a significant increase in the experimental group. Studies included in the -analysis show that educational video patient groups had lower anxiety levels than the control groups after the procedure. Although future studies are required, the results suggest that educational videos effectively prepare patients for diagnostic procedures, improving care quality.
