Evaluating comprehensive cancer networks; a review of standards and evaluation methods for care networks to inform a comparison with the OECI comprehensive cancer network standards.

To ensure that all citizens have equal access to high-quality cancer diagnosis and care, the EU4Health Programme, Europe's Beating Cancer Plan, and Horizon Europe's Cancer Mission propose Comprehensive Cancer Infrastructures in every European Union Member State. It is therefore important to establish the basic principles for high-performing cancer networks and a methodology for evaluating their quality and effectiveness. This article describes methods and standards/indicators for network evaluation found in literature, gives a comparative overview of the new OECI European Cancer Network Quality standards, and proposes principles for evaluating the performance of Comprehensive Cancer Networks as a basis for continuous improvement. We performed a scoping literature review on methods and standards/indicators for care-network evaluation. We then compared the OECI set with literature findings, categorised standards that were similar, reflected on standards that were different, and deduced principles for quality standards for cancer networks. Of 1002 articles identified, 17 reported on evaluation methods and/or (mostly) qualitative indicators. Sixteen studies described indicators/standards for evaluating care networks, critical success factors or desirable outcomes. Of the 54 present OECI standards, 32 had a literature equivalent. No literature equivalent was found for 22 standards, especially on those related to the combination of care and research. The proposed OECI evaluation methods (survey, document review, and interviews) were all reported in the literature. From the conformity of these results, we deduced 8 principles for standards evaluating the effectiveness of Comprehensive Cancer Networks. Research on the evaluation of the effectiveness of care networks is scarce. Evaluation methods vary and are often single time-point assessments. The OECI set contributes to establishing clear principles and standards to evaluate the effectiveness of Comprehensive Cancer Networks.
