HLN Adds Support for Earliest/Overdue Date in Latest Release of Open Source Immunization Forecaster

A new release (v 1.11.1) of the Immunization Calculation Engine (ICE) is now available (Download ICE version 1.11.1). ICE is a state-of-the-art open-source software system that provides clinical decision support (CDS) for immunizations for use in Immunization Information Systems (IIS), Electronic Health Record (EHR) and Personal Health Record (PHR) Systems.

The release includes support for Earliest Date and Overdue Date. 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. In this release, ICE returns the earliest and overdue dates for four vaccine groups: Meningococcal ACWY, Polio, Rotavirus and Varicella. The ICE team expects the remaining vaccine groups will be completely supported in future releases of ICE in Spring 2018.

In addition, this release includes a General Rule update which fixes an issue that resulted in the General Rule “Shots Administered Below Series Absolute Minimum Age for Dose 1” not being triggering when there are 2 or more invalid shots given below the absolute minimum age for Dose 1.

The latest ICE Implementation Guide (v2r19) describes how implementers should update their installation and software to properly read the Earliest, Recommended, and Overdue dates. 

You can determine which release of ICE you are using by viewing the README.HISTORY file that is included with each distribution.
