Background:
Video-based patient education about long-term systemic corticosteroid treatment has not been assessed.
Objective:
To compare video-based versus verbal education in patient knowledge gained and satisfaction.
Methods:
English-speaking adults (≥18 years) were recruited from March-August 2013 from medical dermatology clinics. Study provider clinics were the unit of randomization. Verbal subjects heard a script based on the standard discussions of two top systemic corticosteroid prescribers at Emory. Video subjects viewed a video developed by the investigators. A 12-item survey created by the the investigators assessed baseline and post-education knowledge (immediate, one-, three-, and six-month).
Results:
Baseline knowledge scores averaged 7.2±2.2 correct answers with no between-group differences. Post-education, the video group's (N=39) mean paired score difference was 0.9±2.0 higher than the verbal group's (p<0.04). After 1 month, most scores maintained gains with no between-group differences. 97% of patients in each group were satisfied (none were unsatisfied) with their education.
Limitations:
Our cohort was more literate than the general public, and a minority of subjects completed long-term follow up assessments.
Conclusion:
Video education enhanced near-term patient knowledge more than verbal education and maintained patient satisfaction.

Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
