Abstract
The COVID-19 pandemic caused the suspension at all levels of the Catalan FIT-based CRC screening program on March 12, 2020. Screening invitations to FIT were resumed on September 1, 2020. We aimed to assess the short-term impact of the pandemic and describe strategies implemented to minimize harm by the disruption of the FIT-based CRC screening in the Metropolitan Area of Barcelona. We analyzed participation rate, colonoscopy adherence, time intervals to colonoscopy, detection rates, and advanced-stage cancers in 2019 and 2020. To identify perceived distress levels during the suspension of the screening we conducted a phone interview. As a result of the suspension, 43% of the individuals due for screening did not receive their invitation by December 31, 2020. A percent decrease of 5.1% in participation and of 8.9% in colonoscopy adherence among invitees between January-March was observed, with a recovery to 2019 levels when the screening activities were restarted. The time interval between a positive test to colonoscopy was longer in 2020 than in 2019. A decrease in advanced neoplasia rate and an increase in later stages of CRC were also observed. Individuals with a positive test did not report higher levels of perceived distress compared to those with a negative test. Although the disruption of screening had a temporary impact on participation and colonoscopy adherence, timing delay continues and a large backlog in the invitation of the target population remains. Thus, it is critical to implement strategies to minimize the long-term effects.
