['The objective of this study was to determine if delivery of wound care instruction pre-Mohs micrographic surgery versus the typical, post-Mohs surgery would allow for greater patient retention.', 'A non-blinded, randomized, controlled trial receiving institutional review board exemption from Michigan State University was conducted over a three-month period. Patients scheduled for Mohs surgery on 13 selected days were randomized into pre- versus post-procedure groups to receive wound care education.', 'This study was conducted at a dermatology practice in Saint Joseph, Michigan.', 'Fifty cognitive and literate patients greater than 18 years of age were evaluated in this study.', "PARTICIPANTS' ability to recall instructions delivered by a Mohs surgeon in the form of digital media was assessed by a 10-question, multiple-choice exam. Additional analyses were conducted on patient's disposition around medical professionals, past experience with Mohs surgery, preference for digital media versus human instruction, and desire for home access.", 'Pre- (n=24; score=77±14%) versus post-(n=26; 83±11%) procedure education displayed no significant difference (p=0.13) in overall questionnaire performance. Seventy-four percent of participants preferred video delivery as opposed to provider instruction. Thirty-four percent reported being intimidated by healthcare workers. Participant performance showed no significant change (p=0.78) with previous exposure (79±19%) to Mohs surgery versus a first-time encounter (80±11%).'] Does video education provide effective wound care instruction pre- or post-mohs micrographic surgery?
