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.

Data Management for Large-scale COVID-19 Immunization: This is all not as simple as it seems

There is a global race for the development of a vaccine for the SARS-CoV-2 virus that causes COVID-19. Finding a vaccine that works and receives approval is only part of the process. There are a series of other steps that need to be taken so that the vaccine can be delivered. These include the mass production of the vaccine, shipment, administration and record-keeping. This may be even more complex as there may be several vaccines. In this article we review some of these issues with a particular focus on the United States.

Feature Overlaps Between Immunization Information Systems and EHRs

Immunization Information Systems (IIS) have been around for nearly twenty years. Their functionality, completeness, and usefulness have all increased over this time. IIS and electronic health record (EHR) systems have always had unique features, as well as some overlapping features, and the deployment of EHRs has enhanced the local immunization capabilities of clinician practices. Several critical clinical features that are considered to be core functions of IIS are beginning to be supported by EHRs. This article will review and discuss five such critical features: online data entry, clinical decision support for immunization, reminder-recall, practice-level assessment of up-to-date status, and patient access to their immunization data.

How are Clinical Decision Support Artifacts Tested Today?

In October 2018 the Centers for Disease Control and Prevention (CDC) issued a Request for Information (RFI) for a Natural Test Collaborative (NTC). Through a series of questions, the RFI seeks opinions and information about "The development of a national testbed (notionally called the National Test Collaborative (NTC)) for real-world testing of health information technology (IT)" and "Approaches for creating a sustainable infrastructure" to achieve it. The scope of this RFI is daunting. It might be useful, rather than to try to tackle this whole topic broadly but superficially, to take just one Clinical Decision Support (CDS) domain and show as completely as possible how testing is currently done.
