The investigators investigated the use of portable MP3 technology in patient education and informed consent of shave and punch biopsies. Eighty patients were divided randomly into a control and experimental group. Control patients received the standard of care in patient education and informed consent. Experimental patients watched a short 80-second video on shave or punch biopsies. All patients were given pre- and post-education questionnaires to assess the efficacy of each method.

Primary Outcome Measures:
  • Measure the post-education knowledge of each intervention arm [ Time Frame: at the end of the study visit ]
    Compare the post-education knowledge between the two intervention arms: one conventional informed consent process, the other video-based informed consent process. Knowledge will be measured through a questionnaire administered before and after patient education is given.
