The authors note continuing barriers to broad-based HIE and a shift to vendor-driven exchange which diminishes the effectiveness of community-based networks. In effect, this translates to a shift away from geographic-based/dominated HIEs to product-dominated HIEs. We have already noted (see The Interoperability of Things) the lack of a national strategy on HIE, and ONC’s Nationwide Interoperability Roadmap barely mentions the concept.
As part of the ONC Health IT Certification Program, Congress mandated the establishment of an Electronic Health Record (EHR) Reporting Program to help determine the effectiveness of the program. The first step toward implementation was the development of an initial set of CEHRT developer metrics which were released in draft form in December 2021. When finalized, these metrics will represent data that EHR vendors will have to report to ONC as a Condition and Maintenance of Certification. The initial focus of the metrics developed was interoperability, and public health was one of four categories considered.
An immunization information system (IIS) aggregates immunization information for children (and some adults) living or receiving immunization services in a jurisdiction. One of the core components of an IIS is its immunization evaluation and forecasting system: the computerized algorithm that is used to determine if vaccine doses that were administered to the patient are clinically valid (evaluation) and to project what doses are due now and in the future (forecasting). These algorithms are used to support clinical decision support (CDS) at the point of care and also to help public health agencies understand and manage the immunization status of whole populations.
