Quality and Perceived Usefulness of Patient-Submitted Store-and-Forward Teledermatology Images.

Importance: Patient-submitted images vary considerably in quality and usefulness. Studies that characterize patient-submitted images in a real-life setting are lacking. Objective: To evaluate the quality and perceived usefulness of patient-submitted images as determined by dermatologists and characterize agreement of their responses. Design, Setting, and Participants: This survey study included patient images submitted to the Department of Dermatology at Duke University (Durham, North Carolina) between August 1, 2018, and December 31, 2019. From a total pool of 1200 images, 10 dermatologists evaluated 200 or 400 images each, with every image being evaluated by 3 dermatologists. Data analysis occurred during the year leading up to the article being written. Main Outcomes and Measures: The primary outcomes were the responses to 2 questions and were analyzed using frequency counts and interrater agreement (Fleiss κ) to assess image quality and perceived usefulness. We performed a random-effects logistic regression model to investigate factors associated with evaluators' decision-making comfort. We hypothesized that most images would be of low quality and perceived usefulness, and that interrater agreement would be poor. Results: A total of 259 of 2915 patient-submitted images (8.9%) did not depict a skin condition at all. The final analysis comprised 3600 unique image evaluations. Dermatologist evaluators indicated that 1985 images (55.1%) were useful for medical decision-making and 2239 (62.2%) were of sufficient quality. Interrater agreement for a given image's diagnostic categorization was fair to substantial (κ range, 0.36-0.64), while agreement on image quality (κ range, 0.35-0.47) and perceived usefulness (κ range, 0.29-0.38) were fair to moderate. Senior faculty had higher odds of feeling comfortable with medical decision-making than junior faculty (odds ratio [OR], 3.68; 95% CI, 2.9-4.66; P < .001) and residents (OR, 5.55; 95% CI, 4.38-7.04; P < .001). Images depicting wounds (OR, 1.75; 95% CI, 1.18-2.58; P = .01) compared with inflammatory skin conditions and that were in focus (OR, 5.56; 95% CI, 4.63-6.67; P < .001) had higher odds of being considered useful for decision-making. Conclusions and Relevance: In this survey study including 10 dermatologists, a slight majority of patient-submitted images were judged to be of adequate quality and perceived usefulness. Fair agreement between dermatologists was found regarding image quality and perceived usefulness, suggesting that store-and-forward teledermatology initiatives should consider a physician's individual experiences and comfort level. The study results suggest that images are most likely to be useful when they are in focus and reviewed by experienced attending physicians for wound surveillance, but dermatologists may be burdened by irrelevant or unsuitable images.

A comparison of knowledge acquisition and perceived efficacy of a traditional vs flipped classroom-based dermatology residency curriculum.

Flipped and traditional classroom models were compared in the Duke University Medical Center (Durham, North Carolina) dermatology residency program for the 2014-2015 academic year. The residents participated in 12 lectures-6 traditional and 6 flipped-that were paired for similar content. Each lecture was followed by a survey comprised of 10 factual questions and 10 perception questions. Generalized linear regression models were used to study the differences in quiz scores between the 2 classroom models after adjusting for other baseline covariates. There was not a significant difference in mean factual quiz scores between the two classroom models. Results indicated significant perception differences in favor of the flipped classroom model, such as participation (P < .001), enjoyment (P=.038 and P=.026), efficiency (P=.033), and boards (P=.050) and clinical preparedness (P=.034).

Reasons for tanning bed use: a survey of community college students in North Carolina.

BACKGROUND: Tanning bed use is classified as carcinogenic and is associated with an increased risk of skin cancer. The aim of this cross-sectional survey was to identify the most commonly stated reasons for tanning bed use among a sample of male and female community college students in eastern North Carolina. METHODS: A brief, self-administered survey was distributed to students during English, Art, or Psychology class periods in 5 eastern North Carolina community colleges during the 2010 fall semester. RESULTS: The 95% response rate consisted of 487 returned surveys. Of the 487 respondents, 12.7% (N = 62) were current users, 24.5% (N = 119) were past users, and 62.2% (N = 303) reported never using tanning beds. Women (79%) were more likely than men (18%) to be current or former tanning bed users. Three African Americans reported current tanning bed use (4.8%). Reasons for tanning bed use were similar among men and women, with "I think I look better when I am tan" being the most commonly cited reason (70.2%) for tanning bed use. LIMITATIONS: A convenience sample limits generalizability to all North Carolina students attending community college. CONCLUSIONS: Current tanning bed use was not widely reported. However, educational strategies for preventing tanning bed initiation or recurrence among male and female community college students should include appearance-driven factors.

Pediatric surgical pearls: minimizing complications.

Performing dermatologic surgery in infants and children presents unique challenges. A thorough understanding of both pediatric developmental milestones and their unique surgical circumstances is essential to providing optimal dermatologic care of the pediatric patient. In this work, we combine the authors' experiences with data from the literature to provide pediatric dermatologic procedural pearls.
