Abstract
The impact of the COVID-19 pandemic on dermatology practice cannot be overstated. At its peak, the pandemic resulted in the temporary closure of ambulatory sites as resources were reallocated towards pandemic response efforts. Many outpatient clinics have since reopened and are beginning to experience a semblance of pre-pandemic routine, albeit with restrictions in place. We provide an overview of how COVID-19 has affected dermatology practice globally beginning with the rise of teledermatology. A summary of expert recommendations that shape the “new normal” in various domains of dermatology practice, namely, dermatology consultation, procedural dermatology, and phototherapy, is also provided.

Introduction
The coronavirus disease 2019 (COVID-19) pandemic has substantially impacted medical practice worldwide. At its peak, lockdown measures were implemented in an effort to curb viral spread and reallocate resources and manpower toward the pandemic response. This situation entailed the closure of ambulatory sites that are deemed nonessential, which included dermatology outpatient clinics. As clinics began to reopen, dermatologists were faced with the challenge of navigating clinical practice while adhering to enhanced safety protocols (ie, physical distancing, mask wearing, frequent hand washing), and teledermatology, often referred to as the “new normal.” In this article, we describe how the COVID-19 pandemic has restructured the practice of dermatology and provide a summary of expert guidelines on the safe conduct of dermatology consultations, procedures, and phototherapy in the midst of this global health crisis.
The Rise of Teledermatology
During the height of the COVID-19 pandemic, many workers switched to working remotely to minimize in-person encounters and limit viral transmission. The medical field was no exception, as face-to-face patient encounters have been minimized to reduce the need for personal protective equipment (PPE) in short supply, whereas telemedicine was maximized. Telemedicine is defined as “the use of electronic information and communications technologies to provide and support health care when distance separates the participants.”1 This definition encompasses radio dispatching of emergency personnel, robotic surgery, and telephone and/or video consults.1 Being a highly visual field, dermatology is a field well suited to maximize telemedicine. The term “teledermatology” has been used to describe the use of telemedicine to evaluate skin lesions, review laboratory findings, and diagnose and treat patients remotely.2
First developed during the 1960s, the practice of teledermatology has increased exponentially in recent years.2 Teledermatology has proved to be vital during the peak of COVID-19 restrictions and, even as clinics have reopened, teledermatology continued to account for a significant proportion of overall dermatology visits.3 A recent analysis of trends in teledermatology use found that from May 2020 to June 2020, teledermatology consults for common dermatoses (ie, acne, rosacea, psoriasis, atopic dermatitis, and eczema) increased, whereas consults for skin malignancies decreased.3 This finding indicates that despite the availability of in-person consultation as an option, both patients and physicians felt comfortable addressing benign skin conditions via teledermatology.3 It is therefore reasonable to expect the long-term integration of telemedicine into dermatology practice, which necessitates the development of guidelines for optimal delivery of this service (Box 1 ).

Teledermatology aims to improve access and accessibility to care, increase efficiency, and reduce cost2 , 4; however, it also has limitations. These limitations include technical difficulties (ie, poor Internet connection), privacy concerns, patient challenges with technology, access to technology, and lack of insurance coverage.5 , 6 In addition, there is potential for misdiagnosis due to incomplete history taking, poor photograph/video quality, and inability to perform physical examination (eg, lesion palpation) and diagnostic procedures.6 One review reports that more than half of teledermatology consultations require a subsequent in-person visit.2 Hence, clinicians must assess the appropriateness of teledermatology on a case-to-case basis.7
In-Person Consultation
Trends in average weekly patient visits during the initial phase of the pandemic (mid-February to mid-April) showed an 81% decline (from 149.7 to 28.2), with an uptick observed in mid-May (96.5 patients seen per week), commensurate with the gradual easing of lockdown restrictions in the United States8; this means that from February to May 2020, a potential 10.2 million patient visits were missed, which equates to an estimated decrease in revenue of $2.3 billion.8 In addition, a global Web-based survey of 733 dermatologists revealed that in-person consultation decreased by 54% following the onset of the pandemic, whereas teledermatology use increased 3-fold.9 More than two-thirds of survey respondents expect continued use of teledermatology in the future, further emphasizing its role in dermatology practice beyond the pandemic.9
Nonetheless, despite its increasing acceptability among both patients and practitioners alike, it is unlikely for teledermatology to entirely replace traditional face-to-face consultation. One study found that when presented with the same patient, there was a high degree of concordance (72%) between the diagnosis made by a dermatologist through teleconsultation and another dermatologist through face-to-face visit.10 However, it was also noted that 20% of the patients were deemed unfit for teleconsultation. These patients included those with conditions that cannot be sufficiently diagnosed without closer inspection and palpation, dermoscopy, fungal or viral microscopy, and biopsy.10 Hence, dermatology practice during the “new normal” involves determining whether a patient is suitable for teledermatology or in-person consultation.
Dermatology practices generally fall under the low-risk category for COVID-19 exposure.11 However, according to a study by Gerami and Liszewski,12 a dermatologist is likely to encounter 1 active COVID-19 case per week in the outpatient clinic, given an average of 165 new COVID-19 cases a day in a population of 100,000. Hence, during the pandemic, it is still prudent to have administrative and engineering measures in place to ensure the safety of both patients and staff. The American Academy of Dermatology recommended steps for running dermatology practice during the COVID-19 pandemic, first shared on their Web site in December 2020 (Box 2 ).11

Most interim guidelines, when COVID-19 community spread was high, recommended seeing only urgent and essential cases, decreasing opening days and/or hours, reducing the number of staff per shift, and limiting the number of patients seen per day. Intervals in between appointments were lengthened, whereas the actual patient encounter was limited to as little time as possible (10–15 minutes). With appointment slots limited, triaging of patients for scheduling of in-person consultation became a necessity. Guidelines for prioritizing limited in-person appointments during the height of the pandemic suggested that precedence should be given to the following13:
-
•
Health care workers with skin diseases that interfere with their delivery of service.
-
•
Patients with severe skin diseases that are potentially life-threatening, functionally debilitating, or cause significant impairment to quality of life.
-
•
Diagnostic procedures for confirmatory purposes, especially when the differential diagnosis includes high-risk conditions (eg, melanoma, severe infection, mycosis fungoides, autoimmune blistering diseases).
-
•
Patients with skin disease resulting in significant functional and/or emotional impairment who have no access to or cannot effectively use telemedicine.
-
•
Patients with similar prognoses should be selected randomly as to who gets a particular appointment.
In addition, COVID-19 screening (temperature and symptom check) and wearing of masks became a routine, and in most cases even a prerequisite for a patient or staff member to be allowed entry into the clinic. It is recommended that staff members who are suspected to have COVID-19, either through positive screening or exposure to an infected individual, be sent home and follow the Centers for Disease Control and Prevention (CDC) guidelines for returning to work following a COVID-19 exposure (Fig. 1 ).14 Overall, these adjustments were made to facilitate physical distancing and curtail viral transmission.

Summary of CDC return to work criteria for health care staff who have been exposed to COVID-19. Exposure through close contact is defined by the CDC as being within 6 ft of an infected individual for at least 15 minutes without PPE. A previously asymptomatic staff member who starts to develop symptoms during 10-day isolation or while waiting for COVID-19 test results (dotted arrow) should follow the algorithm for symptomatic health care workers. Per CDC, fully vaccinated individuals (ie, ≥ 2 weeks and < 3 months from receiving requisite vaccine doses) or who have recovered from COVID-19 infection less than 3 months earlier do not have to quarantine after a meaningful COVID-19 exposure as long as they remain asymptomatic.

Procedural Dermatology
Based on a global Web-based survey, only 25% of dermatologists performed procedures during the height of the pandemic.9 Of these, biopsies and Mohs micrographic surgeries (MMSs) were the most commonly performed, whereas cosmetic procedures became exceedingly rare,9 which comes as no surprise, because most interim guidelines in 2020 recommended deferring elective cosmetic and surgical procedures to reduce the risk of COVID-19 transmission and preserve PPE. The International League of Dermatologic Societies defines elective dermatologic procedures as those performed on skin lesions that pose no imminent danger to the patient if not surgically removed within 3 months15; these include acne surgery, chemical peels, laser hair removal, and injectables (botulinum toxin and cosmetic filler injections). Conversely, lesions such as melanoma, atypical melanocytic lesions, or abscess drainage may necessitate prompt management with surgery or other procedures, which should be done during the pandemic under strict infection prevention and control measures (see Box 2).
With regard to MMS, a United Kingdom-based nationwide survey revealed that almost half of surgeons performing MMS completely ceased services during the height of the pandemic, whereas 36% and 15% had reduced and normal operations, respectively.16 To minimize patient visits, those who continued to perform MMS showed an increased preference toward the use of absorbable sutures for wound closure, as well as telecommunications (telephone/video) for follow-up visits compared with before COVID-19.16 On the other hand, post-Mohs reconstructions performed by other specialties were significantly decreased (74%) together with face-to-face consultations (91% decrease).16
In early 2021, the American Society for Dermatologic Surgery together with the American Society for Laser Medicine and Surgery, Inc, released guidelines for the safe practice of cosmetic dermatology during COVID-19 (Table 1 ).17 The document detailed and graded ancillary evidence on various infection prevention and control measures (eg, mask/respirator use, eye protection, and handwashing), as well as the risk of viral transmission associated with certain dermatologic procedures.17

Phototherapy
The COVID-19 pandemic significantly impacted the use of chronic dermatologic treatments, including phototherapy. Many phototherapy centers worldwide were closed during the height of the pandemic, whereas the few that remained open experienced a decline in patient census. In one of the biggest health systems in Israel, the number of patients coming in for phototherapy decreased by more than 50% since March 2020.18 This decrease was found to be primarily driven by patients declining treatment continuation because of fear of contracting the virus; the interruption in care posed the risk of a skin disease flare.18 Photoimmunosuppression may also be of particular concern amid the pandemic, because it is one of the mechanisms by which phototherapy controls skin disease. However, based on clinical experience with human immunodeficiency virus-positive patients, phototherapy is a safe and reasonable option during this time.19
The risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in phototherapy units is currently unknown.20 Although safety protocols observed in other hospital units are largely applicable, there are certain elements unique to phototherapy that require special attention. First, phototherapy involves having a patient come to the clinic multiple times a week, which potentially increases exposure to both the patient and staff. Second, localized treatments (ie, excimer laser or light) entail close contact between the patient and the staff for a prolonged period, and treatment of the face and periorificial areas where patients need to be unmasked puts the staff at even higher risk. Third, full-body treatments, although generally preferred during the pandemic, are typically administered in enclosed booths where patients stand in close proximity to phototherapy equipment surfaces made of plastic or steel.21 This proximity can potentially facilitate viral transmission because SARS-CoV-2 has been found to survive for up to 9 days on these surfaces,21 even though evidence of COVID-19 transmission through inanimate objects is limited. In addition, phototherapy booths normally have fans that are turned on during treatment to prevent overheating, which is potentially aerosolizing and could facilitate viral spread.22
Therefore, the decision to resume phototherapy should be made based on the weight of its perceived benefit versus the potential risks to both patient and staff. Most guidelines recommend prioritizing patients with severe skin disease, those who are more likely to respond to phototherapy, and in cases wherein other options besides phototherapy are limited or unavailable.20 Home phototherapy is also a reasonable option and may even be preferable during this time; however, it may not be feasible for all patients.
If in-office phototherapy is deemed necessary, efforts must be taken to conduct operations as safely as possible. Box 3 lists expert recommendations for operating phototherapy clinics during the COVID-19 pandemic.22 , 23

Future Perspectives
As of February 2021, a total of 72.8 million doses of COVID-19 vaccine have been administered in the United States, most which were first given to health care workers (HCWs).24 In Israel, which was the first country to vaccinate most of their population, fully vaccinated HCWs (2 doses of the Pfizer BioNT vaccine) comprised only 2% of those who contracted COVID-19; this compared favorably to partially vaccinated (1 dose received) and unvaccinated HCWs who comprised 46% and 52% of infections, respectively.25 Hence, with HCWs almost universally vaccinated, it is reasonable to expect that some easing of restrictions may take place. Per CDC guidance as of March 2021, individuals who are at least 2 weeks and less than 3 months from receiving the requisite doses of vaccine, or who have recovered from COVID-19 infection less than 3 months earlier, do not have to quarantine after a meaningful COVID-19 exposure as long as they remain asymptomatic.26 , 27 However, given its unpredictable nature, COVID-19 resurgence is a possibility and may warrant reinstatement of administrative and engineering measures detailed herein. Experts advise that even after receiving 2 doses of COVID-19 vaccine, individuals must still wear masks and practice physical distancing until more information becomes available.28
Clinics care points
-
•
COVID-19 is a rapidly evolving situation with expert recommendations changing at an almost daily basis, therefore, dermatologists must update themselves periodically and make necessary adjustments in accordance with local, state, and federal guidelines and mandates. The points summarized herein represent expert recommendation at the height of the pandemic.
-
•
The appropriateness of teledermatology must be assessed on a case to case basis. Many patients and dermatologists feel comfortable using teledermatology to address common dermatoses; however, lesions which require closer examination (i.e. suspected malignancy) may warrant a face-to-face visit.
-
•
Triaging of patients for scheduling in-person visits may be necessary. COVID-19 screening, wearing of masks, and physical distancing should still be practiced.
-
•
Elective procedures should be deferred in order to reduce the risk of COVID-19 transmission and preserve personal protective equipment, while necessary procedures should be done under strict infection control and prevention measures.
-
•
Many patients are reluctant to resume phototherapy for fear of contracting COVID-19. Home phototherapy, if feasible, is a reasonable option. Otherwise, in-office therapy should be resumed based on the perceived benefit versus potential risks, and should be conducted with safety protocols in place.
-
•
Despite health care workers almost universally vaccinated, COVID-19 resurgence is still a possibility. Experts recommend that fully-vaccinated individuals continue to wear masks and practice physical distancing until more information becomes available.
-
•
As the pandemic winds down, many of these recommendations/precautions can be safely relaxed.
