ABSTRACT

Purpose:

Despite an increasing incidence of skin cancer over the last decade, studies have reported a decline in the diagnosis and treatment of skin cancer during the COVID19 pandemic. We performed a retrospective cohort study using a large population-based cohort from the Veterans Health Administration (VHA) to determine how the pandemic has affected tumor size and morbidity in veterans with periocular non-melanoma skin cancer.

Methods:

Electronic health records from all VHA sites were accessed through the VA Informatics and Computing Infrastructure (VINCI). Data were stored in the Observational Medical Outcomes Partnership (OMOP) model and queried via SQL Server. ICD-10 and current procedural terminology codes were used to identify patients who received Mohs surgery for periocular basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) between 08/01/2018 and 09/10/2021. A combination of structured algorithms and manual review were used to extract patient demographics, lesion characteristics, and surgical outcome at three time points, ie. pre-COVID, early, and late COVID. Unpaired t-tests were used to assess statistical significance.

Results:

Patient characteristics were similar between pre- and post-COVID cohorts in terms of gender, age, race, and tumor type. The average number of Mohs periocular surgeries performed per week were 23.1% (7.31 vs 5.62) and 13.1% (7.49 vs 6.51) lower in the early and later pandemic, respectively, compared to similar pre-COVID timeframes by month (Figure 1). Mean lesion size (maximum diameter) was 1.35 cm larger post-COVID compared to pre-COVID (95% CI 0.19 2.51, P=0.022);however, the defect size remained similar (Figure 2). Stratifying by tumor type, the same trends were noted in BCC, particularly early in the pandemic. However, mean SCC lesion and defect sizes did not vary over time.

Conclusions:

Periocular Mohs surgery rates declined in the COVID pandemic across VHA. Lesions were larger particularly in the earlier phase of the pandemic for BCC. Future analyses using this cohort will attempt to determine if telehealth and travel time were associated with distinct outcomes.
