Keloid Scar
Conditions
Brief summary
The purpose of this study is: * to identify how knowledge about keloid scars and self-treatments differs between patients who use the Internet as a source of information and patients who do not * to determine if patients who are at a high risk of developing additional keloid scars are more or less likely to change their behavior based on an educational information talk about keloid scar prevention
Detailed description
Keloids scars differ from other scar types in that they grow beyond the borders of the injury that caused them. Patients with darker pigmented skin are more likely to develop keloids, and blacks are especially predisposed to keloid formation. Treatment options for keloids are limited in that new keloids often form at the treated location. The limited efficacy of professional treatment options and the harmless appearance of small keloid scars may lead a patient to try to manage their keloid scars on their own. One source of information that patients may turn to for self-treatment advice is the Internet.

|---|---|---|
| To Assess the Impact of an Educational Lecture on Knowledge About Keloid Scars by Comparing Mean Scores Between Knowledge Assessment Questionnaires Administered Before an Educational Lecture and Immediately After an Educational Lecture | immediately before and after a 5 minute educational lecture | 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. |
