Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The interventional group will receive routine consent and then watch a supplementary multimedia video describing their planned surgery which is the exposure.

Routine consent involves verbal consent with the surgeon or senior member of the research team, as usually performed when waitlisted for surgery, to describe indications for surgery and associated complications. It will take 5-10 minutes and be performed at recruitment.

The multimedia video will be delivered immediately after routine consent. The video is an 11 minute video which uses animations to depict and describe the relevant anatomy and indications for surgery, an explanation of the surgery, and the post-operative recovery. The video was not designed specifically for this study and is available for The Australasian Gynaecological Endoscopy and Surgery (AGES) Society members on the AGES website only. It is not available currently to the general public. There is one multimedia video for total laparoscopic hysterectomy and one for total laparoscopy hysterectomy with bilateral salpingo-oophrectomy. This will delivered via email link which will self-destruct.

Given the delays to surgery with the current global pandemic and ever-changing directions to the elective surgery waitlist in Victoria, Australia it will not be possible to know when this exposure will be in relation to the actual surgery. The trial is designed to assess change in outcomes immediately after the exposure and at 4 weeks.

A member of the research team will audit each participant to ensure consent forms are signed before proceeding to the next step of the study. We will use an automated program (REDCAPS) which allows for reminders to participants, and notifications to investigators until consent and questionnaires are completed. We will use email read receipts to check adherence to the intervention.

Behaviour
Comparator / control treatment
The control group will receive routine treatment which is routine consent only, as usually delivered to patients who are not in a study.

Routine consent involves verbal consent with the surgeon or senior member of the research team, as usually performed when waitlisted for surgery. It describes indications for surgery alternatives for surgery, expectations of surgery and associated complications. It will take 5-10 minutes and be performed at recruitment. As the consent is performed by the surgeon or a member of the research team, adherence will be recorded in the study database to confirm it has taken place.

Statistical methods / analysis
The expected number of participants is 34
The required sample size has been calculated using the two sample t test and based on a power test of 0.8 an assumed knowledge difference between groups of 5 and 10% the recommended sample size is 17 per group.
This is in keeping with previous studies published looking at improving informed consent with multimedia videos, which have shown statistically significant differences with sample sizes of 60, 56 and 31.

Summary
Brief summary
We seek to determine whether the use of a multimedia video can enhance consent for patients undergoing a total laparoscopic hysterectomy.

In the era of increasingly complex surgical procedures and focus on patient-centred decision-making, the responsibility on clinicians to provide quality informed consent has never been more critical. In the current surgical climate, the Coronavirus pandemic has meant less face-to-face appointments and further delays from the initial booking appointment to surgery. Various media sources are often informally accessed by patients but these risk misinformation and further confusion. The addition of multimedia videos to routine consent has been shown to increase patient understanding and recall which optimizes informed consent and healthcare outcomes.

This is a randomised controlled trial. Participants will be patients currently on the waitlist for a total laparoscopic hysterectomy at the Mercy Hospital for Women who have already received routine consent with their doctor.

Participants will be assessed on their baseline understanding of the procedure, baseline anxiety levels and health literacy. They will be randomised into two groups. Group 1 will receive additional routine verbal consent. Group 2 will receive additional routine verbal consent and then watch an 11 minute multimedia video. Both groups will complete a questionnaire afterwards to evaluate their understanding of their procedure, anxiety and satisfaction levels which is repeated at 4 weeks. The multimedia video uses animations and text to describe the procedure of a total laparoscopic hysterectomy as well as complications and post-operative recovery.

Our hypothesis is that patients who watch the multimedia video will have a better understanding of their procedure which will be reflected in a higher score in the questionnaire, without a negative impact on their anxiety level.
