Prevalence and impact of health-related internet and smartphone use among dermatology patients.

Health information is increasingly accessible via the Internet and smartphone applications (apps), and patients may perceive these resources as tools for self-education and/or self-diagnosis. The objective of this study was to assess the characteristics of dermatology patients who use the Internet and/or smartphone apps to access health information and to evaluate the impact that these resources have on patients' health care-seeking behavior and interactions with physicians. Online resources offer both opportunities and challenges for dermatologists. Because patients often consult online resources for information about dermatologic conditions and may rely on these resources instead of seeking the care of a dermatologist, it is important for dermatologists to be involved in the development of high-quality online content that educates the public while also emphasizing the need to seek in-person medical care.
