Evaluation of Teledermatology Practice Guidelines and Recommendations for Improvement

The current coronavirus disease 2019 (COVID-19) pandemic has forced dermatology practices to rapidly adopt or expand teledermatology services. To date, teledermatology clinical practice guidelines (CPGs) have not been evaluated for quality. This may hinder the implementation and sustainability of high-quality teledermatology services. The objective of this study is to evaluate teledermatology CPGs by using a comprehensive, validated appraisal tool and provide actionable recommendations for improvement for future guideline developers. A systematic literature search was performed to identify all CPGs published in teledermatology. Identified guidelines meeting inclusion criteria were scored for guideline quality by three researchers using the Appraisal of Guidelines and Research and Evaluation tool (AGREE II). Three guidelines met inclusion criteria, including guidelines published by the American Telemedicine Association, the British Association of Dermatologists, and the Australian College of Dermatologists and the University of Queensland. Each of these guidelines exhibited unique strengths and areas for improvement. Areas of strength include clear objective statements, stakeholder involvement, and clarity of presentation. Areas for improvement include rigor of guideline development, applicability, and editorial independence. All guidelines were determined to be of sufficient quality for adoption based on AGREE scoring. Adoption of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence appraisal framework would improve the rigor of development of each guideline. Administering and publishing questionnaires to assess financial competing interests and external review processes would shed more light on the presence and/or extent of author bias. One inherent limitation of CPG selection criteria is that large providers of teledermatology services, such as the United States Veterans Affairs, were not examined in this review. However, the results of this study provide actionable targets to improve the quality of the teledermatology CPGs examined in this study.
