[The CCM Project "Guidelines for the Social Reporting of Screening Programmes"].

The Social Report (SR) is a form of measurement and reporting, transparency, and communication, essential for sharing decisions, activities, and the value an institution generates with stakeholders from a social responsibility perspective. It is a useful tool for screening programmes to understand their objectives and structure, assess their effectiveness, and promote informed participation by citizens and stakeholders.This contribution explores the implementation of the SR in oncological screening programmes - a project conducted in the CCM 2019 Programme 'Guidelines for Social Reporting of Screening Programmes', coordinated by the Institute for Cancer Research, Prevention and Clinical Network (ISPRO) in Tuscany Region in collaboration with the Centre for Oncological Screenings of Reggio Emilia (Emilia-Romagna Region) and the Population Screening Programmes Service of ATS Valpadana (Lombardy Region) - conducted between 2020 and 2022.The project general objective was to review the Guidelines for Social Reporting of Oncological Screening Programmes developed in 2012. This was achieved through a training and knowledge-deepening phase and an experimental phase in a co-creation logic with all stakeholders involved, particularly with Corporate Management, Regional Screening coordinators, and Associations of citizens and patients.The project had three specific objectives: to spread the culture and practice of social reporting through training courses for professionals working in screening programmes; to experiment with drafting SR in three pilot projects and subsequently update the guidelines; to disseminate the updated guidelines to regional screening coordination and promote informed and conscious involvement of stakeholders.At the end of the project, three SRs were produced for mammography, cervical, and colorectal screening programmes, structured into homogeneous sections and enriched with specific local content. This experience demonstrated the importance of the SR as an accountability tool, but also highlighted difficulties due to the pandemic and the need for earlier and more integrated stakeholder involvement. The updated Guidelines reflect the commitment towards more comprehensive, comparable, and inclusive reporting, to be systematically adopted within screening programmes.
