Mobile Apps for Professional Dermatology Education: An Objective Review

Author and Disclosure Information

Mobile dermatology applications (apps) created for the purpose of educating students and trainees present convenient supplemental learning opportunities. Before these apps can be widely utilized, there must be a method to assess educational objectives, quality, comprehensiveness of content, evidence-based accuracy, user-friendly design, and potential for bias. Herein, an established rubric was used to conduct a graded review of apps spanning general dermatology, skin cancer, and cosmetics, with an additional emphasis on affordability and accessibility for the user.

Practice Points

  • Mobile applications (apps) are a convenient way to learn dermatology, but there is no objective method to assess their quality.
  • To determine which apps are most useful for education, we performed a graded review of dermatology apps targeted to students and residents.
  • By applying a rubric to 36 affordable apps, we identified 18 (50%) with adequate teaching value.

With today’s technology, it is easier than ever to access web-based tools that enrich traditional dermatology education. The literature supports the use of these innovative platforms to enhance learning at the student and trainee levels. A controlled study of pediatric residents showed that online modules effectively supplemented clinical experience with atopic dermatitis.1 In a randomized diagnostic study of medical students, practice with an image-based web application (app) that teaches rapid recognition of melanoma proved more effective than learning a rule-based algorithm.2 Given the visual nature of dermatology, pattern recognition is an essential skill that is fostered through experience and is only made more accessible with technology.

With the added benefit of convenience and accessibility, mobile apps can supplement experiential learning. Mirroring the overall growth of mobile apps, the number of available dermatology apps has increased.3 Dermatology mobile apps serve purposes ranging from quick reference tools to comprehensive modules, journals, and question banks. At an academic hospital in Taiwan, both nondermatology and dermatology trainees’ examination performance improved after 3 weeks of using a smartphone-based wallpaper learning module displaying morphologic characteristics of fungi.4 With the expansion of virtual microscopy, mobile apps also have been created as a learning tool for dermatopathology, giving trainees the flexibility and autonomy to view slides on their own time.5 Nevertheless, the literature on dermatology mobile apps designed for the education of medical students and trainees is limited, demonstrating a need for further investigation.

Prior studies have reviewed dermatology apps for patients and practicing dermatologists.6-8 Herein, we focus on mobile apps targeting students and residents learning dermatology. General dermatology reference apps and educational aid apps have grown by 33% and 32%, respectively, from 2014 to 2017.3 As with any resource meant to educate future and current medical providers, there must be an objective review process in place to ensure accurate, unbiased, evidence-based teaching.

Well-organized, comprehensive information and a user-friendly interface are additional factors of importance when selecting an educational mobile app. When discussing supplemental resources, accessibility and affordability also are priorities given the high cost of a medical education at baseline. Overall, there is a need for a standardized method to evaluate the key factors of an educational mobile app that make it appropriate for this demographic. We conducted a search of mobile apps relating to dermatology education for students and residents.

Methods

We searched for publicly available mobile apps relating to dermatology education in the App Store (Apple Inc) from September to November 2019 using the search terms dermatology education, dermoscopy education, melanoma education, skin cancer education, psoriasis education, rosacea education, acne education, eczema education, dermal fillers education, and Mohs surgery education. We excluded apps that were not in English, were created for a conference, cost more than $5 to download, or did not include a specific dermatology education section. In this way, we hoped to evaluate apps that were relevant, accessible, and affordable.

We modeled our study after a review of patient education apps performed by Masud et al6 and utilized their quantified grading rubric (scale of 1 to 4). We found their established criteria—educational objectives, content, accuracy, design, and conflict of interest—to be equally applicable for evaluating apps designed for professional education.6 Each app earned a minimum of 1 point and a maximum of 4 points per criterion. One point was given if the app did not fulfill the criterion, 2 points for minimally fulfilling the criterion, 3 points for mostly fulfilling the criterion, and 4 points if the criterion was completely fulfilled. Two medical students (E.H. and N.C.)—one at the preclinical stage and the other at the clinical stage of medical education—reviewed the apps using the given rubric, then discussed and resolved any discrepancies in points assigned. A dermatology resident (M.A.) independently reviewed the apps using the given rubric.

The mean of the student score and the resident score was calculated for each category. The sum of the averages for each category was considered the final score for an app, determining its overall quality. Apps with a total score of 5 to 10 were considered poor and inadequate for education. A total score of 10.5 to 15 indicated that an app was somewhat adequate (ie, useful for education in some aspects but falling short in others). Apps that were considered adequate for education, across all or most criteria, received a total score ranging from 15.5 to 20.

Results

Our search generated 130 apps. After applying exclusion criteria, 42 apps were eligible for review. At the time of publication, 36 of these apps were still available. The possible range of scores based on the rubric was 5 to 20. The actual range of scores was 7 to 20. Of the 36 apps, 2 (5.6%) were poor, 16 (44.4%) were somewhat adequate, and 18 (50%) were adequate. Formats included primary resources, such as clinical decision support tools, journals, references, and a podcast (Table 1). Additionally, interactive learning tools included games, learning modules, and apps for self-evaluation (Table 2). Thirty apps covered general dermatology; others focused on skin cancer (n=5) and cosmetic dermatology (n=1). Regarding cost, 29 apps were free to download, whereas 7 charged a fee (mean price, $2.56).
