Impact of the COVID-19 Pandemic on the Diagnosis of Colorectal Cancer within a Population-Based Organized Screening Program.

Background: The interruption of the activity of population-based organized colorectal cancer (CRC) screening programs due to the COVID pandemic may have affected their results in terms of the detection of preneoplastic lesions and CRC. We evaluated the impact of the COVID pandemic on the delays, participation, adherence to colonoscopies, lesions detected, and CRC stage at diagnosis in a CRC screening program.

Methods: We analyzed all the invitations between 1 January 2019 and 31 December 2021.

Polyprev: Randomized, Multicenter, Controlled Trial Comparing Fecal Immunochemical Test with Endoscopic Surveillance after Advanced Adenoma Resection in Colorectal Cancer Screening Programs: A Study Protocol.

Colorectal cancer (CRC) screening programs have been implemented to reduce the burden of the disease. When an advanced colonic lesion is detected, clinical practice guidelines recommend endoscopic surveillance with different intervals between explorations. Endoscopic surveillance is producing a considerable increase in the number of colonoscopies, with a limited effect on the CRC incidence.

[Processes maps in public health organizations: the experience of the Galician Department of Public Health].

To design the processes map of the Galician Department of Public Health, we performed document reviews, held meetings and interviewed persons in charge of programs and departments to identify the processes carried out. The processes were classified into strategic, key and support processes. We defined 4 levels of disaggregation and management and staff were kept informed throughout the process.
