Recent studies conducted by dermatology hospitalists have illustrated the value of asynchronous store-and-forward technology in settings lacking access to consultative dermatology.22,23 Stephens et al22 found that expanding provider-to-provider electronic consultation (e-consultation) capacity to an inpatient rehabilitation facility resulted in completed consultations within 1.5 days compared with a 7- to 14-day wait time for patients attending an in-person urgent access dermatology clinic. In another study, the implementation of asynchronous dermatology e-consultations for immunobullous diseases, vasculitis, and herpes zoster resulted in a change in diagnosis 86% of the time, accompanied by at least 1 new systemic or topical therapy recommendation.23
Researchers also identified ways in which teledermatology can be inelegant and proposed specific supplemental data to aid in diagnosis. A review of 126 inpatient e-consultations demonstrated limitations related to the diagnosis of skin and soft-tissue infections. In two-thirds to three-quarters of cases, potentially useful descriptive information was missing, and in 70% (88/126), images were not appropriately focused. The authors developed a detailed checklist to help primary medical teams focus their differential diagnoses.24 A recent pilot study found that supplementation of clinical information with a standardized questionnaire and thermal images improved the accuracy of cellulitis diagnosis. Using this method, there was no difference in accuracy between dermatology hospitalists and other board-certified dermatologists, supporting the notion that any dermatologist can fulfill this need successfully, even without specific inpatient experience.25 Due to the high incidence and cost of cellulitis and related hospital admissions,26 such an intervention could have a considerable financial and patient safety impact.
Final Thoughts
This last year brought many changes to the health care landscape, the recession of a global pandemic, and an increasingly complex health care delivery system. Inpatient dermatologists met these challenges by providing high-quality dermatologic care and practice-modifying research in the areas of severe cutaneous adverse reactions, supportive oncodermatology, hospital readmission, telemedicine, and more, demonstrating the value of dermatologic expertise in the hospital setting.
