Anatomy of a Public Health Open Source Project: HLN's Immunization Calculation Engine (ICE)

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.

Clinical Decision Support Strategies for Electronic Case Reporting and its Open Source Connection

A key element of public health surveillance is the reporting of infectious and certain non-infectious conditions to state, local, and tribal public health agencies (PHA) around the United States. Historically, there have been a number of key challenges with the process of case reporting that is pervasive in the United States today. To help overcome some of these barriers, an effort has been underway to move the process of case reporting to electronic. A key component of the emerging electronic care reporting (eCR) strategy is the use of clinical decision support (CDS) to help clinical care organizations determine if a reportable condition is present in a patient's record. Multiple approaches have been identified for this CDS service, including a centralized model being implemented today, and several distributed options which will likely become equally viable. Given the size, diversity, and decentralized nature of healthcare enterprises, it is likely that all three approaches for CDS discussed in this article will be deployed simultaneously.
