Sunscreen use while driving.

Abstract

Data regarding patient perceptions and behaviors about sun-protection measures while driving are lacking. This study evaluates patients' awareness of the importance of sun protection while in an automobile, and assesses perceptions about and compliance with sun protection. A secondary objective was to detect any significant laterality in melanoma and nonmelanoma skin cancers. We performed a retrospective survey of patients seen at a Mohs micrographic surgery clinic. Significantly fewer patients reported wearing sunscreen while in an automobile when compared with general daily sunscreen use (52% vs 27%, P < .05). Most respondents did not think they needed to use sunscreen while driving, especially if the windows were closed. Those who believed they were protected from sun damage while in a car were much less likely to use sunscreen (12% vs 46%, P < .05). There was a significant left-sided predominance of nonmelanoma skin cancers, except in patients who used automobiles with tinted windows. This retrospective survey study design is not as ideal as a randomized controlled trial. Additional limitations of this study include small sample size, selection bias, and recall bias. Our results reveal poor patient awareness of and compliance with sun-protection measures while in an automobile. Skin cancer prevention efforts should be modified to specifically address automobile-related sun exposure.
