Guidelines recommend primary care physicians (PCPs) offer patients a choice between colonoscopy and faecal immunochemical test (FIT) for colorectal cancer (CRC) screening. Patients choose almost evenly between both tests but in Switzerland, most are tested with colonoscopy while screening rates are low. A quality circle (QC) of PCPs is an ideal site to train physicians in shared decision-making (SDM) that will help more patients decide if they want to be tested and choose the test they prefer.

Systematically assess CRC screening status of eligible 50–75 y.o. patients and through SDM increase the proportion of patients who have the opportunity to choose CRC screening and the test (FIT or colonoscopy).

Working through four Plan-Do-Study-Act (PDSA) cycles in their QC, PCPs adapted tools for SDM and surmounted organisational barriers by involving practice assistants. Each PCP included 20, then 40 consecutive 50–75 y.o. patients, repeatedly reported CRC status as well as the proportion of eligible patients with whom CRC screening could be discussed and patients’ decisions.

9 PCPs initially included 176, then 320 patients. CRC screening status was routinely noted in the electronic medical record and CRC screening was implemented in daily routine, increasing eligible patients’ chance to be offered screening. Over a year, screening rates trended upwards, from 37% to 40% (p=0.46) and FIT use increased (2%–7%, p=0.008). Initially, 7/9 PCPs had no patient ever tested with FIT; after the intervention, only 2/8 recorded no FIT tests.

Through data-driven PDSA cycles and significant organisational changes, PCPs of a QC systematically collected data on CRC screening status and implemented SDM tools in their daily routine. This increased patients’ chance to discuss CRC screening. The more balanced use of FIT and colonoscopy suggests that patients’ values and preferences were better respected.
