Trial Outcomes & Findings for Assessing and Improving Patient Knowledge About Keloid Scars (Keloids) (NCT NCT01176877)
NCT ID: NCT01176877
Last Updated: 2013-01-03
Results Overview
All subjects completed a written questionnaire to assess knowledge about keloid scars before an educational lecture about keloids, immediately after the educational lecture about keloids, and 3 months after the educational lecture about keloids. This written questionnaire to assess knowledge about keloid scars contained 19 questions related to risk factors for developing keloid scars, keloid scar prevention, and keloid scar treatment. A correct response to a question was awarded 1 point and all correct responses were summed to achieve a total score. Possible total score ranged from 0 to 19. A score of 0 is associated with worse knowledge about keloid scars and a score of 19 is associated with better knowledge about keloid scars.

Participant Flow
Between August 2010 and June 2011, 40 subjects were recruited from patients seen for keloid scars at Northwestern University's dermatology clinic in Chicago, Illinois, and from the general population by advertisements in a local newspaper and Internet classified ads.

Keloid Scar
Subjects over the age of 18 with a clinical diagnosis of keloid scarring were included in the study. First, subjects completed a written questionnaire to collect demographic data, including personal history of keloid scarring, past and present use of keloid scar treatments, and internet access and use to find information related to keloid scars. Second, subjects completed a written questionnaire to assess knowledge about keloids. Next, subjects listened to a scripted, 5 minute educational lecture about keloid scars and then completed a written questionnaire to assess knowledge about keloids. Finally, subjects were contacted by phone 3 months later to complete a questionnaire to assess knowledge about keloids and to answer questions about keloid-related behaviors over the previous 3 months.
