CLINTERVENTIONAL Trial: Impact of Clinical Consultations and Audiovisual Tools in Interventional Radiology

* Objectives: To assess whether the implementation of pre-procedural consultations and the use of explanatory audiovisual tools prior to performing Vascular and Interventional Radiology procedures improve the understanding of interventions by patients, improve satisfaction with the information provided and reduce anxiety experienced by the procedure.
* Methods: We will conduct a two-arm randomized clinical trial that will include patients undergoing Vascular and Interventional Radiology procedures. After consent to participation by signing the informed consent, participants will be randomly assigned to the control group (patients to whom the information about the procedure is provided by the requesting physician) and to the experimental group (patients who, in addition to being informed by the requesting physicians, are attended by interventional radiologists in consultation after previously viewing explanatory videos of the interventions). Multi-choice questionnaires will be used to assess understanding and knowledge of the interventions and validated scales to measure satisfaction with the information provided and anxiety experienced. Knowledge and understanding of the intervention, satisfaction with the information transmitted and the method of transmission, as well as anxiety related to the intervention will be compared between the control group and the experimental group. The Student's t-test and the Mann-Whitney test will be used for the comparison of quantitative variables and the chi-square test and Fisher's exact test for the comparison of qualitative variables. Regression analysis will be used to evaluate associations between variables.
* Expected results: To demonstrate that the implementation of pre-procedural consultations attended by interventional radiologists and the use of educational audiovisual tools prior to performing Vascular and Interventional Radiology procedures improve the understanding of interventions by patients, their satisfaction with the information provided and reduces the anxiety experienced for the procedure.
* Potential impact: It is the first clinical trial that analyzes the usefulness of pre-procedural consultations and audiovisual tools in Vascular and Interventional Radiology, so its results will be very interesting to help standardize clinical practice in Vascular and Interventional Radiology.
