illi News/10052087

PALM DESERT, Calif. - illiNews -- On February 12, 2020, HLN released a new version (v1.22.1) of the Immunization Calculation Engine (ICE). ICE is a state-of-the-art open-source software system that provides clinical decision support for immunizations for use in Immunization Information Systems (IIS), Electronic Health Record (EHR) and Personal Health Record (PHR) Systems.

This version includes important updates including:

• Logic updates to the Pneumococcal Vaccine Group following the latest ACIP guidance.
• Logic corrections for the DTP Vaccine Group and Influenza Vaccine Group.
• A minor modification to how month-based calculations are performed.
• More user-friendly wording for the evaluation reason text and recommendation reason text.
• A new option which, when enabled, returns the supplemental text for evaluations and recommendations where applicable. For the appropriate pneumococcal recommendations, ICE utilizes this feature to return supplemental text that recommends shared clinical decision making, and cites the relevant MMWR.
• A new option which, when enabled, allows client applications to override how ICE would normally evaluate a specified shot (i.e., client applications can indicate that an administered immunization being submitted to ICE for evaluation must be treated as INVALID or VALID per an input parameter).
• ICE now outputs the version of the ICE service in each response.

The full software release is available for download at https://cdsframework.atlassian.net/wiki/display/ICE/Downloads.

The Immunization Calculation Engine, or ICE, is a fully configurable vaccine forecasting/decision support web service tool. Making patient-specific vaccine decisions based on US Government American Council on Immunization Practices (ACIP) clinical recommendations is a very complex task. It requires translating ACIP recommendations - the detailed rules that examine a patient's immunization history and determine if all vaccinations are valid, and what vaccinations might be missing - into computable language for clinical decision support. ICE evaluates a patient's immunization history and generates the appropriate immunization recommendations for the patient. These recommendations are communicated to the clinician at the point of care, as well as the patient, health department or other users.

In developing ICE, HLN worked with the New York City Citywide Immunization Registry (CIR), the Alabama Department of Public Health, and the OpenCDS collaboration which is led by researchers at the University of Utah, Department of Biomedical Informatics. ICE is now in use or being configured for use by several governmental Immunization Information Systems (including in the states of Michigan, New Jersey, Rhode Island, and Vermont, as well as New York City), electronic health record (EHR) systems (including eClinicalWorks, some Centricity sites, and the Indian Health Service's RPMS), the AZOVA Digital Health Marketplace, and the CareDox personal health record. Other EHRs, personal health record (PHR) systems, and Health Information Exchanges (HIEs) can be easily adapted to incorporate ICE logic and clinical decision support into their systems as well.
