Abstract
Quality assurance and improvement of cancer screening programmes require up-to-date monitoring systems and evidence-based indicators. National quality reports exist but the definition and calculation of indicators varies which makes comparison between countries difficult. The NordScreen project aims to facilitate comparison of cancer screening across countries and support quality improvement. It has developed a publicly available Web-based interactive application to access standardized performance and outcome indicators of cervical cancer screening, based on up-to-date Nordic cancer screening register data.
