A randomised study of three different informational AIDS prior to coronary angiography, measuring patient recall, satisfaction and anxiety.

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.
