Abstract
Background
The COVID-19 pandemic disrupted health care delivery, including cancer screening practices. This study sought to determine the impact of the COVID-19 pandemic lockdown on colorectal cancer (CRC) screening relative to social vulnerability.
Methods
Using the Medicare Standard Analytic File, individuals 65 years old or older who were eligible for guideline-concordant CRC screening between 2019 and 2021 were identified. These data were merged with the Center for Disease Control Social Vulnerability Index (SVI) dataset. Changes in county-level monthly screening volumes relative to the start of the COVID-19 pandemic (March 2020) and easing of restrictions (March 2021) were assessed relative to SVI.
Results
Among 10,503,180 individuals continuously enrolled in Medicare with no prior diagnosis of CRC, 1,362,457 (12.97%) underwent CRC screening between 2019 and 2021. With the COVID-19 pandemic, CRC screening decreased markedly across the United States (median monthly screening: pre-pandemic [n = 76,444] vs pandemic era [n = 60,826]; median Δn = 15,618; p < 0.001). The 1-year post-pandemic overall CRC screening utilization generally rebounded to pre-COVID-19 levels (monthly median screening volumes: pandemic era [n = 60,826] vs post-pandemic [n = 74,170]; median Δn = 13,344; p < 0.001). Individuals residing in counties with the highest SVI experienced a larger decline in CRC screening odds than individuals residing in low-SVI counties (reference, low SVI: pre-pandemic high SVI [OR, 0.85] vs pandemic high SVI [OR, 0.81] vs post-pandemic high SVI [OR, 0.85]; all p < 0.001).
Conclusions
The COVID-19 pandemic was associated with a decrease in CRC screening volumes. Patients who resided in high social vulnerability areas experienced the greatest pandemic-related decline.
