Randomized Trial Evaluating the Effectiveness of the General Practitioner Involvement in Cancer Screening Invitations

Not Applicable

Completed

• Conditions: Breast Cancer; Colorectal Cancer; Cervical Cancer
• Interventions: Other: Revised invitation signed by the attending physician; Other: Normal invitation; Other: revised invitation signed by the coordinating doctor

• Registration Number: NCT02367001
• Lead Sponsor: University Hospital, Tours

Brief Summary

Our goal is to evaluate, in France, the effectiveness (in terms of participation) of the general practitioner involvement (signature) and a more personalized communication in invitation letters to organized screening of breast, colorectal and cervical cancers.

The hypothesis on which this project is based is that communication is probably more effective if the "receiver" feels personally targeted by invitation letters (Dear Martin, I am writing ...) and if he knows "the issuer "(his general practitioner rather an unknown person).

Primary Outcome Measures

Name	Time	Method
Evaluate the effect on the participation (of the population) in cancer screening of an intervention involving the general practitioner (integration of signature) in the invitation letters	9 or 12 months after the invitation letters	The participation / non participation will be measured for each cancer screening (breast, colorectal and cervical) : * 9 months after the invitation letters for breast and colorectal cancers; * 12 months after the invitation letters for cervical cancer; The participation rate is defined as the number of people having participated, divided by the total number of people in the group or subgroup considered.; Analysis by comparing the participation rates between groups (Group 1, Group 2 and Group 3) and sub-groups will be done.

Secondary Outcome Measures

Name	Time	Method
Evaluate the effectiveness on the participation (of the population) of the use of a simplified and more focused communication in the invitation letters : comparison of the participation rates in arm 1 (normal invitation) and arm 2 (revised invitation)	9 or 12 months after the invitation letters
Cost-effectiveness of different strategies for each cancer screening (breast, colorectal and cervical) as measured by cost effectiveness ratio (total costs in Euros divided by total screened people)	9 or 12 months after the invitation letters
Evaluate the effectiveness on the participation (of the population) of the two types of general practitioner signature (typed versus typed + handwritten) by comparing the participation rates between two sub-groups in the arm 3.	9 or 12 months after the invitation letters
