Impact of Training Patient-centered Approach on Shared Decision in Colorectal Cancer Screening

Colorectal cancer (CRC) affects 95% of cases of people aged over 50 years old with an average age of diagnosis of 71 years for men and 73 years for women with a higher prevalence in women. By the age of 75, 4 out of 100 men and 3 out of 100 women will have developed colorectal cancer.

In France, CRC screening is based on a guaiac faecal occult blood test in subjects at risk average, carried out every 2 years from 50 to 74 years old. In the event of a positive test, a colonoscopy should be performed. Participation in the programme colorectal cancer screening has been declining since 2016-2017.

The implementation of screening faces many barriers on the physian's side and/or on the patient's side. During of the last 2020-2021 screening campaign, only 6.1 million people took a screening test, which represented a participation rate of 28.9%, while it is commonly admitted that a screening rate \>50% would be necessary to reduce CRC mortality.

Some barriers are specific to CRC screening. for patient, reluctance to carry out screening, analysis of stools, and fear of cancer. For the physian, the discomfort in approaching screening and the uncertainty of the relevance of the test for some patients. The know-how and quality of information and communication with patients is at the forefront.

Physian must adapt their communication to the possibilities understanding of the subject to explain, convince, and bring the patient to carry out screening. Active listening is a technique particularly suitable for adopting a person-centred approach making it possible to take into account the patient perspectives in order to arrive at a shared decision.

This most often involves helping and giving the patient the means to manage their problems, involving them in a prevention project (non-requesting patient) or supporting them and motivating them in their approach (requesting patient).

The hypothesize of this study is that training general practitioners in a patient-centered approach will enable the implementation of greater shared decision-making work with the patient during a CRC screening presentation consultation.

• Evaluate the effect of training on the CRC screening rate [Срок оценки: Measurements taken 6 months after the last patient was included in the trial, i.e. no later than 18 months after the start of the trial]
• Confronting the shared decision made by the patient regarding the completion of CRC screening [Срок оценки: Measurements taken 6 months after the last patient was included in the trial, i.e. no later than 18 months after the start of the trial]
• Explore understanding of the shared decision process among general practitioners and patients [Срок оценки: Data collected immediately after the inclusion visit]
