Prevention At PRImary CAre Level - Increasing HPV Vaccination in Lyon.

The PAPRICA study aims to test if an intervention directed to General Practitioners (GP) to train them in methods for recommending HPV vaccine with greater confidence and efficiency is effective to increase HPV vaccination coverage in France. As each health professional is associated in France to a specific reference number i.e. "RPPS number", RPPS numbers for all General Practitioners (GP) from the city of Lyon will be randomly allocated either to the intervention arm or to the control arm to ensure that each arm contains 50% of the total number of GPs. After allocation, GPs in the allocation arm will be identified and invited to attend the intervention i.e. a 3-hour workshop at IARC in the presence of HPV vaccination specialists. The effect of the intervention on the HPV vaccination coverage in Lyon will be measured through HPV vaccines reimbursement data extracted from the Inter-Scheme National Information System within the National Health Insurance System (SNIIR-AM : Système National d'Information Inter-Régimes de l'Assurance Maladie ). Linkable data between girls and General Practitioners (GP) via RPPS numbers will allow us to allocate girls either in the intervention or the control arm. Vaccination coverage will be estimated within each of these cohorts.
