Larry Yuhasz, National Practice Leader, Truven Health Analytics. Physician network development is a top priority for most health systems. Establishing longstanding relationships with the right physicians is critical to not only ensuring a competitive referral base, but also to locking up the right mix of healthcare services for payment reform. Clinical integration strategies are necessary to connect this network to patient data and establish a platform for care coordination. Yet that network isn’t fully mature until it has the means of consistently measuring its performance and acting on it. This session focuses on key phases of a network maturity model that evolves from affiliation to engagement to coordination to performance. Each phase aligns with requisite investments in HIT infrastructure, workflow tools, and analytical applications. The end stage of the network maturity model is an aligned health system that has the full capacity to manage overall population health. Special emphasis is placed on how to lay an analytical foundation that can support higher and higher levels of network maturity, including data aggregation, measures development, dashboard creation, gap analysis and risk stratification, predictive modeling, intervention efficacy studies and risk-based contract evaluation.
