On August 10, 2018, HLN released a new version (v1.14.1) 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.
The release completes support for Earliest Date and Overdue Date for all vaccine series in ICE’s default schedule. If enabled, ICE will output two additional forecast dates along with the Recommendation Date: the Earliest Date and Overdue Date. The Earliest Date is the soonest date that the vaccine can be given and still be considered valid. The Overdue Date is the date after which an immunization administered would be considered late. Completing support for Earliest Date/Overdue Date is an important milestone for ICE. HLN will be presenting this new version this week at the annual meeting of the American Immunization Registry Association (AIRA) and week of August 20 at the CDC Public Health Informatics Conference.
The latest ICE Implementation Guide (v2r20) describes how implementers should update their installation and software to properly read the Earliest, Recommended, and Overdue dates. The relevant information starts on page 43. Note that a “track changes” version of this same guide is also available. The tracked changes are intended to make it easier for the reader to see what has changed in the Guide since the prior release of the ICE Implementation Guide (v2r18).
