A Randomized Controlled Trial Evaluating the Use of a Multimedia Video to Improve Consent in Patients Undergoing Total Laparoscopic Hysterectomy

Study Objective

To evaluate whether a supplementary multimedia video improves surgery-related knowledge in patients undergoing total laparoscopic hysterectomy for benign indications. Secondary outcomes included anxiety and satisfaction levels.

Design

Randomized controlled trial.

Setting

A tertiary teaching hospital in Melbourne, Australia.

Patients

Patients on the surgical waitlist for a total laparoscopic hysterectomy (TLH) for a benign indication, aged 18 years or above, and English speaking.

Interventions

An 11-minute multimedia educational video regarding TLH.

Measurements

Patient comprehension of the surgery was measured by knowledge scores in a 14-point TLH knowledge questionnaire. This knowledge questionnaire was administered at 3 separate time points: baseline (T1) upon study entry, post-intervention (T2), and 4 weeks post-intervention (T3). The primary outcome was knowledge scores at T2 following randomization and intervention.

Main results

43 patients were randomized from July 2022 to December 2023: 21 patients in the control arm and 22 patients in the video arm. There were no significant differences in baseline patient characteristics between groups. At baseline (T1), the median score on the TLH knowledge questionnaire was equal for both groups at 5.0. Following the intervention at T2, the video group scored significantly higher than the control group (median score of 10.0 vs. 8.0, p <.001). At 4 weeks (T3), knowledge scores declined in both groups but remained significantly above baseline in the video group. Anxiety levels assessed using the 6-item Spielberger State-Trait Anxiety Inventory were not significantly different between groups.

Conclusion

Our study demonstrates that the use of a supplementary multimedia video improves informed consent for patients planned to undergo a total laparoscopic hysterectomy reflected in increased knowledge of the procedure, without increasing patient anxiety levels.
