On October 15, 2019, HLN released a new version (v1.21.1) 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:

• Updated HPV rules as per the June 2019 ACIP approved recommendations, including a harmonized recommendation for catch-up vaccination for males and females through age 26 years and recommendation based on shared clinical decision making for individuals aged 27 through 45 years who are not adequately vaccinated.
• Slight change to the way the dose number included in the vMR output is determined.
• A duplicate shot/same day fix whereby a non-combination shot might be selected instead of the combination shot.

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. The ICE code systems and codes are now accessible in Google Sheets as an added convenience. These are the codes as those in the Implementation Guide. The codes will be updated in both the places.

On August 28, 2019, HLN released a new version (v1.20.1) 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 to the DTP Vaccine Group including:

• Updated the Adolescent Tdap Recommendation and Evaluation rules as per the latest Tdap guidance included in the 2019 CDC Immunization Schedule.
• Added a rule requiring that in order for the primary series to be complete via the DTP 3-dose series, at least one of the doses administered must be a pertussis-containing vaccine.

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.

On May 31, 2019, HLN released a new version (v1.17.1) 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:

• Improvements to handling of duplicate shots. Duplicate shots typically represent “bad data” that has been passed into the ICE service. For two or more duplicate shots on the same day, ICE will select the vaccine that makes the most sense for the circumstance. See Two Shots, Same Vaccine Group, Same Day Exception Rules for the specifics on how this is handled for each vaccine group.
• Logic updates to DTP, HPV, and Zoster vaccine groups. See Release Notes for details.
• Pneumococcal interval fix in the Adult Series where (under certain circumstances) the PPSV to PPSV 5 year recommended interval is not being applied when there is a valid PCV shot in between the PPSV shots.

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.

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.
