[Validation of an instructional therapeutic tool to demonstrate cardiac catheterization].

The scope of this work was to validate a toy and a narrative as an instructional tool to present to children who are to be submitted to cardiac catheterization. Content validation was performed by 23 specialist judges (storytellers, child educators, nurses, medics, educational psychologists, occupational therapists, and a psychologist), by using a form considering the following topics: goals, structure and presentation, as well as relevance. Quantitative data was analyzed through the Content Validation Index (CVI) and a cutoff of 0.80 was adopted. Qualitative data was then submitted to thematic content analysis. The toy is composed of: figurines representing the child, the healthcare team, and the person responsible for the child, prototypes of the angiography equipment and the anesthesia equipment, and objects used in hospital for anesthetic induction and vein puncture. The narrative addresses the physical structure of the Hemodynamics room and all steps comprising pre-, trans- and post-cardiac catheterization in a playful way. The technology was validated by the judges with a total CVI of 0.95. The validated toy and narrative constitute a dialog between health, education and art that may contribute to integral and humanized care to the child.
