Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will receive video-assisted consent or usual care when informed consent is undertaken for cardiology procedures.
Arm 1 (video-assisted consent)
Arm 2 (usual care)
The intervention is one short video animation (approximately 5 minutes) that discusses the risks, benefits and alternatives of the cardiology procedure, and will be watched on a computer or tablet computer in the doctor's clinic or hospital. The animations are narrated by a voiceover artist from a script constructed by cardiology specialists. These videos have been designed specifically for the study. The animation will be watched by the patient and a research assistant will supervise to ensure that the video is watched in its entirety by the patient. All participants will be offered the opportunity to ask questions after the video has been watched or after the doctor has undertaken informed consent. Only one video is watched by the participant, and only one video is available for the procedure.
