The problem of integrating heterogeneous clinical data sources across multiple across organizations has been one of primary barriers to RHIO adoption. Clinical data sources can vary from widely-used, standards-compliant products to custom data formats particular to an organization. The CareEvolution RHIO Technology Platform addresses this problem with an architecture that hosts reusable, modular drivers that – like the data sources they integrate – can be standards-based, product-based, or completely customized. Hosting these drivers within this architecture allows the CareEvolution RHIO Technology Platform to provide unified administration, configuration, and monitoring tools for an organization’s various systems and interfaces. By providing “out-of-box” integration solutions when possible and customized integration solutions when necessary, all within a unified architecture, the CareEvolution RHIO Technology Platform can effectively address the range of integration challenges with maximum reuse and manageability.
