Training cosmetology students in Arkansas to help dermatologists find skin cancers earlier: results of a cluster-randomized controlled trial.

Abstract

We tested an educational video in cosmetology schools to increase students' knowledge about skin cancer, sun-safety practices, identifying suspicious lesions and recommending clients consult a dermatologist when a suspicious lesion is observed. We used a cluster-randomized controlled study design to randomize 22 cosmetology schools to receive our educational video or a publicly accessible healthy lifestyle video (control). Students who received the intervention were more likely than controls to increase their knowledge of skin cancer, risk factors and how to identify potential skin cancers (risk ratio [RR] and 95% confidence interval=2.86 [1.58-5.20]). At follow-up, students in the intervention group were more likely than those in the control group to look for suspicious moles on their clients' faces, scalps and necks (RRs=1.75, 2.16 and 2.90, respectively). Additionally, students in the intervention group were more likely to communicate with clients about sun-safety practices (RR=1.74 [1.11-2.73]) and consulting a dermatologist about suspicious moles (RR=1.57 [1.03-2.41]). Our educational video helped cosmetology students recognize potential skin cancers and talk with clients about sun safety and consulting a dermatologist about suspicious moles. Such videos may play a role in the public health surveillance of skin cancers in communities.
