EBCN Meeting Budapest, 24 September 2004 Update on individual data monitoring projects QT and SEED Antonio Ponti CPO Piemonte Torino, Italy

SEED and QT Audit Systems Their aim is two-fold: 1) to favour the implementation of European Guidelines (with training and certification implications), and

SEED and QT Audit Systems 2) to provide a service to screening programmes and Breast Units to meet their management and evaluation needs.

Advantages of monitoring Individual vs Aggregate screening data (1) - Use of common definitions and rules in the process of collecting the minimum dataset: an “educational” process

Advantages of monitoring Individual vs Aggregate screening data (2) - Standard analysis of common dataset, including standard reports on European outcome measures

Advantages of monitoring Individual vs Aggregate screening data (3) - Much more flexible analytical approach

Projects and Partners (6 Countries)

European Benchmarking Within the project described we have attempted to bridge guidelines with screening and care evaluation, while providing databases useful for daily management of screening programmes and patient care.

European Benchmarking This could serve as a model for other health care areas, particularly colon and cervical cancer for which screening programmes are being offered throughout Europe.

European Benchmarking Another bridge is being built: with Cancer Registries networks in the framework of population high resolution studies.

European Benchmarking The quality cycle entails a continuous updating of the audit tools in the framework of a comprehensive European activity.

European Benchmarking In the meanwhile QT is freely available to anyone and SEED could be used by local and regional screening programmes wishing to mutually agree to share it and concur in its development.
