Quality of endoscopic screening for colorectal cancer in Italy: A national survey. Issue 10 (October 2022) - Maida, M.
Abstract: Background: Colorectal cancer (CRC) is a major healthcare problem all over the world and screening is effective in reducing mortality and increasing survival. Since colonoscopy has a central role in faecal immunochemical test (FIT)-based CRC screening and surveillance, consistent quality measures are essential to ensure quality and outcomes. Nevertheless, screening modalities in clinical practice may differ according to the centers experience and the local availability of instrumentation and devices. Aims: to assess the quality of endoscopic screening for CRC and adherence to international guidelines across Gastroenterology Departments in Italy. Methods: All members of the Italian Society of Gastroenterology (SIGE) were invited to answer a web-based survey. Results: Data from 64 hospitals from 17 Italian regions were analyzed. 32/64 (50.0%) were from northern, 12/64 (18.75%) from central and 20/64 (31.25%) from southern Italy. Each center is equipped with a median of 5.0 (3.5-7.0) endoscopists involved in CRC screening, 71.4% of which are gastroenterologists. After a positive FIT, most centers (93.8%) schedule a colonoscopy within 3 months. High-definition video endoscopy is routinely performed in 68.8% and chromoendoscopy in 53.1% of centers. Withdrawal time is ≥6 min in 79.9% and cecal intubation rate is ≥90% in 94.4% of departments. Finally, in 92.7% of centers adenoma detection rate (ADR) overcome the minimum standard of 25%. Analyzing the data by regional areas, a significant higher number of median endoscopic examinations/year (6500 vs 4000 and 3000, respectively, p = 0.024) and of endoscopists per center (6.5 vs 5.0 and 3.5, respectively, p < 0.001) has been registered in the northern compared to central-southern centers. Conclusions: Data from this survey show adequacy and good quality of endoscopic screening for CRC in Italy, highlighting, at the same time, relevant deficiencies and a discrepancy in procedural attitudes between the different centers. These findings call for a urgent action to overcome the shortcomings, refine and homogenize the behaviour of all screening centers in the national territory and improve the outcomes.
