Excerpt

Current News

  • Upcoming Release of ICE (Early September 2021)
    • COVID-19 Update:
      • As always, HLN is actively monitoring all news and updates in regards to new and existing COVID-19 vaccines.  Currently, we are working on adding additional support and logic in ICE to handle the following:
        • COVID-19 Booster DosesAdditional Dose - a dose administered when the immune response to a standard primary vaccine series is likely not to be protective. 
          • Note - A “booster” dose of vaccine is a dose administered to restore protection after the effectiveness of protection from the primary series has declined. ACIP does not recommend booster doses at this time. 
        • COVID-19 Vaccines Not Authorized by FDA, but Authorized by WHO
          • Note - The current release of ICE, Version 1.29.1 supports the handling of one COVID-19 vaccine that falls under this category - AstraZeneca COVID-19 vaccine (CVX 210). 
        • COVID-19 Vaccines Not Authorized by the FDA or WHO

    • Live Virus Bug Fix:

      • Fix bug where, in certain circumstances, ICE is incorrectly recommending Varicella or MMR 28 days later rather than on the same day.

    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.


  • May 14, 2021 - New Release of ICE - Version 1.29.1
    • A new release of ICE is available.  Download the latest ICE release now.
    • Version 1.29.1 includes the following additions and updates. Please see the Release Notes for details.

      • COVID-19 Update: 

        • Updates have been made to expand age ranges down to >= 12 years old for the Pfizer COVID-19 Vaccine (CVX 208).
        • Recommendations have been updated to recommend COVID-19 vaccine to patients >= 12 years old. 
        • Support has been added to handle AstraZeneca COVID-19 vaccine (CVX 210) shots reported on the patient record.
          • As of now, the AstraZeneca COVID-19 vaccine has not yet been approved for use in the U.S. by the FDA, but is approved by the WHO. Please see the COVID-19 Vaccine Group page for details.
          • When the FDA approves the AstraZeneca COVID-19 vaccine (CVX 210) for use in the U.S., ICE will be updated as necessary.
        • In addition to the above updates, added evaluation reason code VACCINE_NOT_APPROVED_IN_US to the ICE Implementation Guide. 
      • Influenza Update:
        • Influenza 2021-2022 Season rules remain unchanged from last season. ICE has been updated to reflect that.
      • Updated Implementation Guide
    • As always, you can determine which version of ICE you are currently using by viewing the README.HISTORY file that is included with each zipfile distribution.
    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.


  • ICE Plans for COVID-19 Implementation
    • HLN is actively monitoring all news and updates in regards to new and existing COVID-19 vaccines.  
    • Once a vaccine has been approved for use by FDA (either Expanded Access, EUA, or full licensure), ACIP will hold an emergency meeting and publish recommendations in a very quick timeframe (i.e. days). HLN intends to release a version of ICE that includes COVID-19 forecasting as early as possible after ACIP has published the guidelines. This initial release will contain COVID-19 logic known at the time of the release. As additional, actionable information on COVID-19 forecasting becomes available from official sources, HLN will continue to release additional versions of ICE, at appropriate times to reflect ongoing updates.
    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.


  • The Importance of Upgrading After Each ICE Release
    • With each new release, we strongly recommend that all users and service providers update their running instances of ICE as soon as possible to the latest version. Each new release contains important forecaster business logic updates and bug fixes.


  • ICE Code Systems and Codes Now Available in Google Sheets
    • 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 continue be updated in both the places.
    • The Google Sheet is available here.


  • Configuration Note
    • As of release 1.24.1, the ICE service is configured with the output_supplemental_text option in the properties file set to enabled by default.
    • As of release 1.16.1, the ICE service is configured by default to return the earliest and overdue dates in addition to the recommendation date. In prior releases, the default configuration was to return only the recommendation date for the forecast.
      • If your application has not been configured to display the earliest and/or overdue dates, we recommend turning this feature off by changing the output_earliest_and_overdue_dates value in the ice.properties file to "N". Failure to do so may result in incorrect interpretation of the recommendation date. 
      • If you are interested in returning the earliest date or overdue date, please refer to the latest ICE Implementation Guide for details indicating precisely where each of the forecast dates – earliest, recommended, and overdue – are specified in the ICE output, and under what circumstances.

    • There are no changes to the ICE Implementation Guide since 1.23.1. However:
    • Note that the following configuration files and directories have minor modifications from prior releases: ice.properties, log4j and knowledge module directory location. If you are updating from a previous release of ICE and wish to change any of the properties in these files, the changes will need to be made in these files directly as the prior files will not work.
    • As always, you can determine which version of ICE you are currently using by viewing the README.HISTORY file that is included with each distribution.
    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.

    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.

...

  • February 12, 2020 - New Release of ICE - Version 1.22.1
    • A new release of ICE is available. 
    • Version 1.22.1 includes the following additions and changes. Please see the Release Notes for details for all of the below:
      1. Logic updates to the Pneumococcal Vaccine Group in accordance with the latest ACIP guidance.
      2. Bug fixes for the DTP Vaccine Group and Influenza Vaccine Group.
      3. Minor modification to how month-based calculations are performed. 
      4. In an effort to make the information returned by ICE to the end user more clear, the evaluation reason text and recommendation reason text have been reworded to be more user-friendly. The ICE SME WG worded these in a way that we believe is suitable for end users. These display values are documented on the Evaluation and Recommendation Codes page and returned by ICE in the displayName attribute of the applicable XML element. The corresponding coded values have not changed.
      5. A new option, output_supplemental_text. If this option is set to "Y" in the ice.properties file, ICE may return supplemental text in the response.
        • By default, this option is not enabled.
        • The ICE Implementation Guide specifies where and how in the response the supplemental text is output for evaluations and recommendations. 
        • This option is utilized by the Pneumococcal Vaccine Group for shared clinical decision making in the recommendation (interpretation element). The Pneumococcal rules page specifies the circumstances in which this occurs. If this option is disabled, the Pneumococcal logic will still operate correctly; applications simply won't benefit from additional text which may be displayed on the screen.

      6. A new option, enable_dose_override_feature. If this option is set to "Y" in the ice.properties file, client applications can override how ICE would normally evaluate a specified shot. The feature enables client applications to indicate that an administered shot must be treated as INVALID or VALID, as specified by the input message. Typically, this feature would be used when there is a vaccine efficacy concern (e.g. - an incorrect administration, vaccine expiration, etc.).

        • By default, this option is not enabled.
        • We suggest that this feature, if used at all, be used with caution and only under certain circumstances such as those described above and in accordance to how it operates. Users should carefully consider the use cases and experiment with the feature so that are no unexpected results.
        • More information about this option is available on Dose Override Feature page.
      7. ICE now outputs the version of the service in the response. See Version Number in the Response Message for details.
    • The ICE Implementation Guide has been updated. The ICE code systems and codes are also accessible in Google Sheets as an added convenience. Changes include:
      • New evaluation & reason codes: SUPPLEMENTAL_TEXT and OUTSIDE_SERIES.
      • Update evaluation and recommendation reasons to the user-friendly display text described above. 
      • Information on how to use the dose override feature.
    • As always, you can determine which version of ICE you are currently using by viewing the README.HISTORY file that is included with each distribution.
    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.


  • January 22, 2020 - A Few Updates
    • The next release of ICE, Version 1.22.1, will be available in February. This release will include logic updates to the Pneumococcal Vaccine Group.
    • The ICE distribution is now available as a docker image which can be download from Docker Hub at https://hub.docker.com/r/hlnconsulting/ice. Moving forward, whenever a new version of ICE is released, the distribution will be available both from Docker Hub as well as from the standard zip file location that we have always used.
    • We are in the process of moving the source code over to GitHub. Once this is complete and we have released the next version of ICE, we will make an announcement and remove the source code from BitBucket.
    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.

      1. Logic updates to the HPV Vaccine Group according to the latest ACIP guidance. See the Release Notes for details.
      2. A tweak to how the dose number value, returned in the vMR doseNumber element, is determined. The Release Notes contains details.

  • May 31, 2019 - New Release of ICE - Version 1.17.1
    • A new release of ICE is now available.
    • Version 1.17.1 includes the following additions and changes:
      1. Logic updates to DTP, HPV, and Zoster vaccine groups. See Release Notes for details.
      2. 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.
      3. 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.
      4. The Release Notes contain further details about the changes in this release.
    • Configuration Note: As of release 1.16.1, the ICE service is configured by default to return the earliest and overdue dates in addition to the recommendation date. In prior releases, the default configuration was to return only the recommendation date for the forecast.
      • If your application has not been configured to display the earliest and/or overdue dates, we recommend turning this feature off by changing the output_earliest_and_overdue_dates value in the ice.properties file to "N". Failure to do so may result in incorrect interpretation of the recommendation date. 
      • If you are interested in returning the earliest date or overdue date, please refer to the latest ICE Implementation Guide for details indicating precisely where each of the forecast dates – earliest, recommended, and overdue – are specified in the ICE output, and under what circumstances
    • As always, you can determine which version of ICE you are currently using by viewing the README.HISTORY file that is included with each distribution.
    • If you have any questions, comments or suggestions, we would very much like to hear from you! Please feel free to e-mail us anytime at ice@hln.com.

    • A new release of ICE is now available.
    • Version 1.16.1 includes the following additions and changes: 
      1. 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.
      2. 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.
      3. Minor logic changes to the Meningococcal B, Polio, Rotavirus and Pneumococcal vaccine groups.

  • February 27, 2018 - Quarterly ICE Review Board Meeting
    • On February 27, 2018, HLN convened its second quarterly meeting of the ICE Review Board. While the inaugural meeting last Fall provided an introduction and information on ICE fundamentals and development processes, this latest session focused on topics ranging from the newest release of ICE that includes Earliest Date and Overdue Date for several vaccine groups; an update on the continued alignment of CDC CDSi and ICE; recent efforts to deploy ICE; and innovations such as, support for FHIR and CDS Hooks. A case study of utilizing ICE after nonviable vaccine administration was presented, and an open dialog was facilitated of relevant public health-related topics and trends. The next ICE Review Board meeting is  being planned for the 2nd quarter 2018.


  • March 9, 2018 - New Release of ICE - Version 1.11.1
    • A new release of ICE is now available.   
      • Version 1.11.1 includes the following additions and changes:
        1. 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 4 vaccine groups: Meningococcal ACWY, Polio, Rotavirus and Varicella. The ICE team expects the remaining vaccine groups to be completely supported by Spring 2018.
          • Note that this feature is disabled by default to ensure existing client applications do not break. Implementers can enable the earliest/overdue date feature by setting the output_earliest_and_overdue_dates property setting in ice.properties file to "Y". Please refer to the ICE Implementation Guide for details about where each of the forecast dates – earliest, recommended, and overdue – are specified in the ICE output, and under what circumstances.
        2. General Rule Update: Fix that resulted in the General Rule "Shots Administered Below Series Absolute Minimum Age for Dose 1" not triggering when there are 2 or more invalid shots given below the absolute minimum age for Dose 1.
        3. An update to the ICE Implementation Guide. The latest ICE Implementation Guide (v2r19) 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 to see what has changed in the guide since the prior release (version 1.10.1.0).
    • ACIP updates for Zoster and MMR will be available in the next release, scheduled for early April.
    • As always, you can determine which version of ICE you are currently using by viewing the README.HISTORY file that is included with each distribution. The Release Notes page contains information about this and prior releases of ICE.
