Summary:Background Informed consent is a basic standard of care for all patients undergoing medical procedures, but recall of information has been shown to be poor. We sought to compare verbal, written and animated audiovisual information delivery, during consent for coronary angiography, by measuring improvement in recall. Method A sample population of 99 cardiac patients at Flinders Medical Centre was randomised (1:1:1) to receive one of three information delivery methods. The information content was standardised by a risk proforma, which explained the procedure and defined 12 specific risks. Recall, satisfaction and anxiety were assessed by a questionnaire administered at three different time points: post-consent, post-procedure and at 30 days. Effect of delivery method on satisfaction and anxiety was rated on a self-reported scale from 1–5, with 5 representing very satisfied or very anxious. Groups were compared by non-parametric testing and a p -value of
