Abstract

Background: The COVID-19 pandemic has increased barriers to accessing preventive healthcare. This study identifies populations disproportionately underrepresented in screening and surveillance colonoscopies during the COVID-19 pandemic.

Methods: In this single-center cohort study, colonoscopy procedures were reviewed during 6-month intervals before the pandemic (July 1, 2019 - December 31, 2019) and during the pandemic (July 1, 2020 - December 31, 2020 and January 1, 2021 - June 30, 2021). 7095 patients were categorized based on procedure indication, demographics, Charlson Comorbidity Index and Social Vulnerability Index (SVI). Statistics performed using VassarStats.

Results: 2387 (2019) colonoscopies pre-pandemic and 2585 (2020) and 2123 (2021) during the pandemic were identified. There was a decrease in colonoscopies performed during months when COVID-19 cases peaked. The total number of average CRC risk patients presenting for first colonoscopy declined during the pandemic: 232 (10 %) pre-pandemic to 190 (7 %) in 2020, 145 (7 %) in 2021 (p < 0.001). Fewer of these patients presented from highly vulnerable communities, SVI > 0.8, during the pandemic, 39 in 2019 vs 16 in 2020 and 22 in 2021. Of all screening and surveillance patients, fewer presented from communities with SVI > 0.8 during the pandemic, 106 in 2019 versus 67 in 2020 and 77 in 2021.

Conclusion: It is important to address the decline in CRC preventive care during this pandemic among average CRC risk first-time screeners and vulnerable community patients. An emphasis on addressing social determinants of health and establishing patients in gastroenterology clinics is imperative to promote future health in these populations.
