Those involved in improving healthcare quality and reducing costs know that data are power. Data are the raw material that health care systems need to rebuild care and payment systems that deliver value rather than volume. Data are what engaged consumers use to make informed decisions about their care, what payers and purchasers use to design value-based benefit packages, and what government and public health entities use to make policy decisions. All of these players need access to uniform, actionable data in order to effect change. Through the ​Aligning Forces for Quality program, Alliances have built sophisticated data aggregation infrastructure and data analysis capability that provides community stakeholders with access to these data. As Alliances transition from grant-supported to revenue-generating business models, they offer a number of insights into how a community can realize economies of scale and value in data aggregation.
