This is a fundamental step to then move to more systematic public reporting and to appropriately link payment to outcomes, quality and high-value care. It can consist of various data sources such as mortality statistics, specific clinical registries (such as a cancer or diabetes registry), administrative databases, electronic health records (EHRs) and surveys conducted on specific patient groups or households. Depending on the quality and comprehensiveness of the data infrastructure, such data sources can serve as a tool not only to assess volumes of care and inputs within the health care sector, but also to monitor quality in the provision of care (OECD, 2013a).
