Can Video Clips Improve Patient Comprehension at the Emergency Department?

The aim of this study is to assess the utility of two interventional videos, showed to patients discharged from the ED with a diagnosis of atrial fibrillation or deep vein thrombosis. We have focused our attention on these two medical conditions because they share some important features: they are frequently seen in EDs; their main complication (stroke and pulmonary embolism) can cause significant morbidity and mortality; both conditions and their related complications are probably not very intuitive to comprehend for the general population. In fact, the understanding of these conditions implies the knowledge of a number of pathological processes, with which most people are unfamiliar. The primary hypothesis is that patients enrolled in the study group will show a higher degree of comprehension of their medical condition and its related complications, as compared to the control group. Secondly, we will also analyze any possible effect of the videos on the knowledge of the therapy prescribed, return instructions and patients' satisfaction with the quality of communication in the ED. Eventually, we will examine the association of some factors with the outcomes (age, sex, level of education, atrial fibrillation vs. deep vein thrombosis group).
