Background:
Multimedia educational materials have been found to improve aspects of informed consent, although data in the context of Mohs micrographic surgery (MMS) is limited.
Objective:
To assess whether a preoperative educational video decreases anxiety, increases comprehension, and improves overall satisfaction for patients undergoing same-day office consultation and MMS.
Materials And Methods:
This single-center randomized controlled trial included patients above the age of 18 years undergoing MMS for skin cancer between October 2015 and December 2015. Patients were randomized to view a short preoperative video on MMS in addition to traditional informed consent versus informed consent without video viewing. Questionnaires were used to assess preoperative anxiety, knowledge, and satisfaction.
Results:
From 231 consecutively enrolled subjects, there were no significant differences in anxiety (p = .626) or satisfaction (p = .065) between groups. Subjects receiving the intervention were able to more accurately recognize risks of MMS (88% vs 69% of controls, p < .001) and had improved subject-reported confidence in understanding procedural risks and benefits (89% vs 71% of controls, p = .049). Composite comprehension scores were similar between groups (p = .131).
Conclusion:
A preoperative MMS educational video increased recognition of procedural risks, but did not improve patient anxiety or satisfaction.
