Abstract
PurposeTo evaluate COVID-19's longitudinal impact on screening mammography volume trends. MethodsHIPAA-compliant, IRB-approved, single institution, retrospective study of screening mammogram volumes before (10/21/2016–3/16/2020) and greater than two years after (6/17/2020-11/30/2022) a state-mandated COVID-19 shutdown (3/17/2020–6/16/2020) were reviewed. A segmented quasi-poisson linear regression model adjusting for seasonality and network and regional population growth compared volume trends before and after the shutdown of each variable: age, race, language, financial source, risk factor for severe COVID-19, and examination location. ResultsAdjusted model demonstrated an overall increase of 65 screening mammograms per month before versus a persistent decrease of 5 mammograms per month for >2 years after the shutdown (p < 0.0001). In subgroup analysis, downward volume trends were noted in all age groups <70 years (age < 50: +9/month before vs. −7/month after shutdown; age 50–60: +17 vs. −7; and age 60–70: +21 vs. −2; all p < 0.001), those identifying as White (+55 vs. −8, p < 0.0001) and Black (+4 vs. +1, p = 0.009), all financial sources (Medicare: +22 vs. −3, p < 0.0001; Medicaid: +5 vs. +2, p = 0.006; private insurance/self-pay: +38 vs. −4, p < 0.0001), women with at least one risk factor for severe COVID-19 (+30 vs. −48, p < 0.0001), and screening mammograms performed at a hospital-based location (+48 vs. −14, p = 0.0001). ConclusionThe screening mammogram volume trend more than two years after the COVID-19 shutdown has continued to decline for most patient populations. Findings highlight the need to identify additional areas for education and outreach.
