Version 3.10 - Production

Version 3.10.11 - Release November 19, 2014

Production ready version. The following changes were made:

• Diphtheria: Fixed issue where if first dose given after 7 years of age was a Td and a Tdap on the same date the transition did not work properly.
• Fixed forecasting issue where concurrent requests to the forecaster can cause one of the requests to fail. This was found to happen when sending a volley of 100,000 messages in 10 threads at the forecaster (a level not expected to be done in any of the current production systems.) It was determined that if two requests were processed at the exact same time that one of them could fail. The problem is now fixed and the forecaster can process a continuous stream of requests from up to 10 sources without problems and without slowing down.

Version 3.10.10 - Release October 10, 2014

Production ready version. The following changes were made:

• Influenza: Fixed issue where H1N1 given was being seen as a regular flu season dose. Caused logic for determining second dose to not work properly.
• Diphtheria: Fixed issue with missing grace period for a single transition (K5).

Version 3.10.9 - Release October 3, 2014

This version is ready for production use. Includes minor fixes identified during user acceptance testing.

• Diphtheria: Fixed transition in childhood schedule when child becomes late, so that it transitions appropriately under specific circumstances from the 3rd dose to the 4 year old catchup dose.
• HPV: Fixed due date for second dose for males to match females for dose two.
• Influenza: Fixed issue with not recognizing H1N1 vaccine in flu rules and added CVX code to list of vaccines.
• MMR & Varicella: Changed MMRV administration so that if given after 13 it is still counted as valid. (MMRV should not be given after 13 but can be counted as valid if done.)
• Polio: Fixed transition from 3rd dose for children under 4 year old to move to P4 instead of catchup booster. Not a major change except it keeps the patient from being shown as overdue for fourth dose.

Version 3.10.8 - Release September 19, 2014

This version is ready for production use. One minor fix from previous release.

• Fixed logic for * dose counts. Previously it was reporting dose 0 or 1, when it should have been reporting 1 or 0. This only affected certain catchup doses that requiring counting to set dose number.

Version 3.10.7 - Release September 18, 2014

This version is intended for production use. Very minor changes from previous version.

• Diptheria: Changed transition for alternative primary schedule for children to go to K4 if 3rd dose is given after 4 years of age. Updated K4 valid and overdue dates to more expected values.
• Hib: Set alternative catchup dose to have a variable dose number depending on how many valid doses given before.
• Pneumo: Set alternative catchup dose to have variable dose number and updated valid, due and overdue dates on catchup schedule to more appropriate values.

Version 3.10.6 - Release September 17, 2014

This version is intended for production use. Very minor changes from previous version.

• Hib: Minor fix to schedule for a catchup schedule.
• Polio: Minor fix to schedule for a catchup schedule.
• IHS Interface: Added support for reporting back CVX codes of parts of message that are invalid.

Version 3.10.5 - Release September 16, 2014

This version should be ready for production use. A few minor changes were made, but testing is nearly complete.

• Diptheria: Changed age transitions to happen 4 days before the actual age, so a Tdap given at 7 years - 4 days is considered valid for adult schedule.
• Hib: Changed age transitions to include 4 day grace period.
• Pneumo: Changed age transitions to include 4 day grace period.
• Polio: Changed age transition to include 4 day grace period, fixed issue with transition not happening when 2nd dose given after 4 years of age.

Version 3.10.4 - Release September 8, 2014

This is a testing release, and may be ready for production use. It must be tested first.

• Diphtheria: Modified Tdap so that it counts if DTaP or DTP is given.
• Influenza: Added support for new CVX 161 code.
• Hib: Added new Catchup Booster dose to correctly mark vaccination as overdue immediately.
• Polio: Added new Catchup Booster dose to correctly mark vaccination as overdue immediately.

Version 3.10.3 - Release August 29, 2014

This is a testing release, and will likely not be released for production use. Please note that many of the fixes listed below are not known to be problems in the current production release. Rather they are fixes to problems introduced in the previous patch.

• Pnuemo: Added a state C4 for dealing with a first and final dose differently than a final dose after other vaccinations.
• Hib: Added back in some transitions for doses given instead of by age. This allows the dates to stay the same until a dose is given. This is a good balance between age transition and dose transition on certain ages.
• Polio: Fixed 4 year old transition on P3. A typo caused it not to work.
• Influenza: Fixed issue with H1N1, should have been fixed before but forgot to copy over XML in last release.
• Diptheria: Another state was added to manage when the 4th dose is not given on time. Fixed logic for determining if Tdap had been given previously. This was not working in the previous patch so it was impossible to transition to the final 10 year booster.

Version 3.10.2 - Release August 27, 2014

This is a testing release, and will likely not be released for production use. Please note that many of the fixes listed below are not known to be problems in the current production release. Rather they are fixes to problems introduced in the previous patch.

• Hib: Reworked the Hib Diagram based on feedback from Brady during testing.
• Diphtheria: Found a problem with transitions on age if a vaccination give on the day of transition. Fixed bug by giving priority to transition.
• Diphtheria: Fixed issue with not properly transitioning to booster dose when tdap is given.
• Diphtheria: Tdap given as a booster (K5 and P4) will count as a valid transition for children under 7. P1, P2, P3, P1a, P2a, P3a will still count as invalid.
• Influenza: Change to influenza moved the valid date to the first date when the flu shot could be given regardless of the season. This was different than the previous version that moved the valid date to the start of the season. Now the valid date will be adjusted to start of season if before the season. This should reduce differences between this version and previous versions.
• Influenza: Contraindication of the Live Flu was affecting the due date of the standard recommendation. That has been fixed.
• Influenza: Added H1N1 codes to the standard list of flu codes, otherwise logic did not work correctly.
• Influenza: The tester was showing "unknown" status for a vaccination series that was complete. This was because the flu now does not report the next dates due, and should have been moved to a different section of the report. That has been done so now the tester should show the status correctly.
• Influenza: Fixed issue with seasonal overdue date not set correctly.
• Polio: Fixed minor issue on transition so it worked properly. (4 Years Old was valued as '7 months' and so did not work properly.)
• PCV: Removed extra state that was added in the previous version.
• PCV: Added new state to handle when the 3rd dose has not yet been given and should be immediately given.

Version 3.10.1 - Release August 20, 2014

This is a testing release, and will not be released for production use. Five forecast antigens have been completely rewritten:

• Diptheria: Completely new transitions from DTaP to Tdap.
• Hib: New diagram and transitions.
• Influenza: Major change to how forecasting is done. Completely new diagram and logic for driving second dose decision. Incorporates 2014 ACIP rules.
• Pneumo: New diagram and transitions, support for PCV-13 supplemental dose after a PCV-7 series has been removed.
• Polio: New diagram and transitions.

Changes specific to Influenza:

• Valid date for influenza is now always 6 months after the birth of the patient and will never reflect start of season.
• The previous seasons are now all lumped together as simply previous doses that do not count towards completion. Minimum 4 week intervals and live virus conflicts are still checked, but not determination is made about compliance with 2 dose requirements in the seasons before the current one.
• The transition diagram has bee simplified by the introduction of a new concept of Decision Logic that is written custom to determine transition from the first seasonal dose to possibly a second season dose. This simplifies and standardizes the flu schedule. However, when ACIP changes their schedule, the Decision Logic piece will have to be rewritten. This will require a new release of the flu forecast.

Version 3.9

Version 3.9.4 - Released June 17, 2014

Final set of improvements for Spring 2014 release

• Version was incremented because of a major fix to the logic for determining the valid intervals between invalid and valid administration of vaccinations. The TCH Forecaster now applies the invalid interval only to the previously given invalid dose and the valid interval to the previously given valid dose. This change aligns with the intention of the means of the valid and invalid interval values. While this change is fairly big from the sense of logic it's impact is only minor as most invalid and valid intervals are the same. Only in a few scenarios was this problem evident.
• HPV: Male schedule was not setup exactly the same as female schedule. Apparently improvements made previously to female schedule were not applied to male. Male schedule is now aligned with female.
• Hep A: Increased grace period between invalid administration of 2nd dose and next valid administration of 2nd dose. The forecaster will not recommend a 6 month gap but will accept the 2nd dose as soon as it can be given after the 1st dose.
• Varicella: Removed requirement that 2nd dose be given at 15 months (with a grace period of 8 weeks). Now only the minimum interval of 12 weeks (with a grace period of 8 weeks) is enforced.
• For IHS version fixed issue with Hep A child/parent doses not being properly coded for the forecaster.
• For IHS version added filter so that specific vaccinations doses would be forecasted on the valid date and others on the early date when the IHS user requested an accelerated schedule. Issue 59
• Diphtheria: Added a 6 week early due for all first doses. This only affects those who select to use the early due date.

Version 3.8

Version 3.8.4 - Released April 24, 2014

Improvements for IHS deployment and TCH deployment.

• Fixed issue with Influenza IIV being improperly contraindicated when given after Varicella.
• Moved report version to top of report for IHS.
• Fixed issue with Influenza forecast not working properly when given immediately at the start of the season on July 1st.
• Made minor changes to the Java API, for integration into TCH system.
• Added setting the influenza season in the IHS forecaster.
• Added filter for Influenza so IHS is not forecasted for flu after 04/01 of every season.
• Added contraindications for Flu LAIV4 that were only working before for Flu LAIV3.
• Added temporary fix to IHS version to not report back invalid Hep B for Pediarix when given between 2nd and 3rd dose.
• Fixed issue displaying text for invalid reason on detailed forecast report.

Version 3.7

Version 3.7.1 - Released April 2, 2014

Improvements for IHS deployment.

• Added new field to Forecast Options - Recommend When Valid. If set to true, the forecaster will indicate vaccinations that are due today because the valid due date has now been satisified. Normally this does not ocurr until the due date is reached. This option may be used to forecast as soon as possible for patients.
• Mening will now not forecast for 19+ years of age. Considered to be finished by that age.
• Fixed minor spelling issue.
• Fixed interface issue for IHS to indicate to valid or invalid vaccinations.
• Change report format for IHS so that lines are deliminated by special characters.

Version 3.5.12 - Released March 28, 2014

Improvements found after testing with IHS and TCH test cases:

• The early due and early overdue functionality were further improved. Previously the forecaster reported out these data separately and let the report writer or receiver of the data to decide which to show. Now the forecaster will only report due and overdue dates, but can use the alternative early dates if the Forecast Options indicate that this should be done. This change had to be made as the forecaster has a fair amount of logic around due and overdue dates that gets very complicated if both of these dates and their early twins must be considered. Now the logic sets the dates correctly early on and the rest of the logic flows normally from there.
• Change overdue date for second MCV4 from 19 years to 17 years.
• Fixed issue with influenza season setting function was not resetting properly to default. Caused a problem only for testing.
• Fixed issue with Hib forecast finishing too soon rather than completing evaluation of series. Did not affect final result recommendation.
• Fixed issue with Java API interface not returning results properly.
• Fixed issue with MCV4 not showing up in IHS (was showing on report but was not transmitting to IHS in proper format).
• Fixed issue with DTaP not showing early overdue date for IHS. Forecaster was working properly but IHS connector was not properly indicating need to send back early date.
• Fixed issue with influenza contraindication now engaging at the correct time. Results were accurate but appears of contraindication was unnecessary and confusing.
• Compact report for IHS now does not include irrelevant forecasts. The supporting text below however gives all details.

Version 3.4

Version 3.4.1

Changes for Indian Health Service and Texas Children's Hospital:

• Added support for assumptions for adults who are assumed to have received childhood series. The forecaster will not automatically assume an adult record has received childhood immunizations. Rather, these must be asserted at the time of the request.
• Added ability to ignore vaccinations that are sub potent. This is a preliminary ability and needs to be further tested before being used in production.
• Added ability to force a vaccination to be valid even if given too soon. This is a preliminary ability and needs to be further tested.
• Changed MMR and Varicella interaction so that they have a 28 day separation instead of a 24 days.
• Added support for MenHibrix in Hib schedule.
• Fixed two minor issues with IHS interface.

Version 3.3

Version 3.3.1

Changes to the detailed information associated with each vaccine type forecaster for and changes to the IHS interface.

• Added invalid code and invalid reason to the IHS defined interface.
• Changed how the detailed logging is done so it can be displayed either in HTML or plain text. This change was needed to support IHS need to display details in text format. This change resulted in a major change to the interface for reporting back details. Previously there was a traceBuffer available that included details on entire forecast process, but this was redundant with the details in each trace log. So the traceBuffer has been removed.

Version 3.2

Version 3.2.6

This latest release has the following major improvements:

• Updated support for CDC CVX codes. Previous versions did not properly support all codes.
• Integrated ability to report on exactly how codes are supported. This insures accurate documentation of functionality of forecaster.
• Reporting on status of all vaccine types forecasted for. Previously if a patient was finished or complete for a vaccine series no recommendations or forecasts were given. The recipient was required to assume that the patient did not need these vaccinations. Now the interface reports back statuses on all vaccinations, even if they are no longer relevant.
• The Influenza forecast can now split if a contraindicated live vaccine is given within 28 days of a recommended for Influenza. If this happens the forecaster will report a recommendation for Influenza IIV to be given on time and a contraindicated forecast for Influenza LAIV to be given at a later date. The new status field on the result indicates that a dose is currently contraindicated and the dates indicate when the vaccination should be given.

It is important for API users to understand the need to filter results before displaying to the end user. The forecaster now returns a great deal more information some of which may not be relevant. For example, all patients, regardless of age, will receive a Rotavirus forecast. For most patients this forecast will simply indicate the patient is finished or complete. These type of results would not normally be shown to clinicians giving regular care. Please consult the API documentation to understand how to properly interpret the results.
