On June 21, 2024, HLN released a new version (v1.43.1) of the Immunization Calculation Engine (ICE) in support of updates to the COVID-19 vaccine. 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.
Version 1.43.1 includes the following additions and changes. Please see the Release Notes for details.
- Meningococcal B: Added support for CVX 316, Meningococcal MenABCWY (Penbraya). Addressed an issue in the series selection rules that resulted in (under certain circumstances) the incorrect series being selected.
- Meningococcal ACWY: Added support for CVX 316, Meningococcal MenABCWY (Penbraya).
- Influenza: Added support for CVX 320, Influenza, MDCK, trivalent, preservative.
- DTP: Added recommendation reason codes ADMINISTER_TDAP_OR_TD and SUPPLEMENTAL_TEXT, with descriptive text, “Administer either Tdap or Td” to the recurring booster dose recommendation.
- MMR: Addressed an issue in the proof of immunity logic.
- Varicella: Addressed an issue in the proof of immunity and disease documented logic.
- Hep A / Hep B: Addressed an issue in the proof of immunity logic.
- A new property, disable_covid19_sep2023_dose_number_reset, was added to the ice.properties file. If enabled, ICE will not reset the dose number to 1 when recommending the Sept 2023 COVID-19 >= 5y series. This option is disabled by default, aligning with the behavior in the last version.
The ICE Implementation Guide has been updated to include CVX 316 and CVX 320. A Google Sheet that lists all the coded values in the Implementation Guide is also available.
