On March 7, 2019, HLN released a new version (v1.16.1) 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:

• DTP Vaccine Group: Added an update to the "Six by Seven" rule to explicitly state that duplicate shots on the same day do not count towards this rule. The intention of this change is to prevent potentially "bad data" that may be passed into the ICE service from affecting the forecast result.
• Hib Vaccine Group: Improved handling of duplicate shots administered on the same day. For details, please refer to the Two Shots, Same Vaccine Group, Same Day Exception Rules page.
• Minor logic changes to the Meningococcal B, Polio, Rotavirus and Pneumococcal vaccine groups.

HLN recently demonstrated ICE integrated into two EHRs at the HIMSS19 Interoperability Showcase starting in February in Orlando, FL.

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