Treatment Adherence in Dermatology During the COVID-19 Pandemic: A Review

The coronavirus disease 2019 (COVID-19) pandemic raised many challenges for dermatology. Safety is a principal concern for many patients, particularly those on medications that affect the immune system. Understanding how the pandemic affects patients' treatment adherence may be informative for counseling or other interventions to assure that treatment plans are not inappropriately interrupted, or for future pandemics. The purpose of this review was to investigate the extent to which the COVID-19 pandemic affected medication adherence in dermatology. A literature search of PubMed was performed using the search terms: adherence, compliance, dermatology, COVID-19, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), and pandemic. Eleven primary research studies met the inclusion criteria and were included in the review. During the COVID-19 pandemic, non-adherence in dermatology patients was primarily linked to concern about the risk of COVID-19 infection with long-term use of immunomodulatory and immunosuppressive medications. In some cases, non-adherence was associated with feelings of depression, anxiety, or perceived stress. High adherence was attributed to regular and convenient communication between patients and dermatology providers through the effective use of telemedicine and electronic messaging. Frequent communication with providers to address patient concerns and provide continuity of care improved adherence. An integrated virtual approach to patient care facilitated this, particularly through the use of telemedicine. Implementation of routine virtual questionnaires was, to some extent, effective in replacing limited in-person patient-provider interactions during the pandemic. Finally, the added threat of the pandemic presented an additional mental health component to consider for patients, supporting the need for a multidisciplinary approach to patient care.
