Further study details as provided by Institut National de la Santé Et de la Recherche Médicale, France:

Primary Outcome Measures:
  • Completion of colorectal cancer screening [ Time Frame: 2 years ]
  • Reduction of social inequalities [ Time Frame: 2 years ]
    The participation rate to the colorectal cancer screening will be compared between privileged and deprived geographical areas for which the socio-economic status is measured with the Townsend index.

Secondary Outcome Measures:
  • Estimation of Cost effectiveness [ Time Frame: 2 years ]
    We will assess the mean cost to navigate one person and compared it to a non navigate person. We will measure the cost effectiveness of the intervention in order to have the cost of the arising of 1% of the participation rate.

  • Evaluation of psychological mechanisms [ Time Frame: 2 years ]
    Evaluation of cognitive, behavioural, emotional mechanisms influencing the colorectal screening participation

Arms Assigned Interventions
Experimental: With Patient Navigator
People in this arm receive the Intervention of a Patient Navigator
Other: Patient Navigation
Insured people receive firstly a letter to inform them that a patient navigator is available to navigate them during the colorectal screening steps. A free telephone number and the navigator schedule is given. After a minimum of one week the patient navigator begins the telephone outreach.
No Intervention: Control - Without Patient Navigator
People in this arm receive just the usual care of colorectal cancer screening
