Scientific title
Study objectives	Audiotaping outpatient consultations could improve informed consent in cardiac surgery
Ethics approval(s)	This trial was approved by the Institutional Ethics Committee of Glasgow Royal Infirmary in November 2004
Health condition(s) or problem(s) studied	Coronary artery disease
Intervention	The participants were randomly allocated to three trial arms. The control group (Group A; n = 29) received no tape. The 'generic' group (Group B; n = 25) received a copy of a tape which contained general information about coronary artery surgery which we scripted to include information covering each of the domains described by the General Medical Council. The 'consultation' group (Group C; n = 30) received a tape of their consultation interview.
Intervention type	Other
Primary outcome measure	Impact of audiotape in improving the informed consent process, as measured by a knowledge questionnaire, in cardiac surgery. The assessment was carried out a day before surgery within 2 hours of signing the consent form. Publication of the result of a pilot study to design and validate the knowledge questionnaire can be found at http://www.ncbi.nlm.nih.gov/pubmed/16932081
Secondary outcome measures	Impact of audiotapes on the Health Locus of Control Scale and the Health Anxiety and Depression Scale. The assessment was carried out a day before surgery within 2 hours of signing the consent form.
