Easier i2b2 Install
The i2b2 server can now be installed using a pre-built war file instead of having to build it from source, or the war file can be built from source much more easily. More information is in the updated Installation Guide. The properties files are now stored in the database.
...
Authentication Protocol Support for NTLM2/OKTA
User Set up with OKTA Configuration: On the Admin page, under Manage Users,
Add a Parameter domain and assign the values as below. Parameter value will be your institution domain name.
Add a second parameter domain_controller as below. Parameter value will be your institution domain_controller value
Add the final parameter authentication_method as below. Parameter value will be OKTA
User Set up with NTLM2 Configuration: On the Admin page, under Manage Users,
Add a Parameter domain and assign the values as below. Parameter value will be your institution domain name.
Add a second parameter domain_controller as below. Parameter value will be your institution domain_controller value
Add the final parameter authentication_method as below. Parameter value will be NTLM2

Currently, the following REDCAP Features are supported in i2b2.
- Project level :
- Only one unique redcap project id can be assigned to each i2b2 project( system finds the first project it encounters and assigns it, so two projects cannot have same REDCAP project id:
- Form level:
- Renaming a Form in Redcap will create a new record in table access instead of updating the original record which means in i2b2 the original survey will still show in Ontology in addition to creating the renamed survey as a new Ontology item.
- On adding a new Field/editing a field in the REDCAP form, the form needs to be explicitly associated with the record again to take effect in i2b2
- Data triggers happen only on Form SAVE button.
- Only Form SAVE as a URL survey or Admin edit/add record Saves, triggers i2b2 Ontology creation. Other forms of Form creation in REDCAP- by Data import tool, API format, will not trigger Ontology creation in i2b2)
- Ontology is only displayed in Tree structure format in i2b2. Pop up display (sometimes called query-by-value) is not supported. (example as below)
- There is no mapping of records submitted in REDCAP to existing patient_ids in i2b2. The scope of this release is limited to adding new record rows in Observation_fact table and Updating the fields of records added.
- Field level:
- The following project fields from REDCAP are supported in i2b2.
- TEXT BOX
- CHECKBOX
- RADIO BUTTON
- DROPDOWN
- YES-NO
- TRUE-FALSE
- SLIDER / VISUAL ANALOG SCALE
- DESCRIPTIVE TEXT
- NOTES BOX
- SIGNATURE
- DYNAMIC QUERY(SQL)
- Text box (Short text)Number and Date/Time ) with Validation capability in REDCAP - validation will work only as a simple text String search in i2b2
- Check box, Multiple Choice , Yes-No, True-False Form fields will appear as a Tree format in i2b2 ( Popup display is not supported)
- The following project fields from REDCAP are supported in i2b2.

1) Set Project Params (PM_PROJECT_PARAM)

Totalnum Scripts for Postgres and MSSQL have been updated to improve the Totalnum counter performance on very large(>1.5 million) ontology elements such as ACT medications, Debug messages have also been added for troubleshoot purposes
Totalnum Scripts Setup
- In the Release_1-7/NewInstall/Metadata/ run the ant script to create the stored procedures. ant ant -f data_build.xml create_metadata_procedures_release_1-7 7
- Run the stored procedures on your database. This can be done in two ways.In the Release_1-7/NewInstall/Metadata/ run the ant script to create the stored procedures.
- POSTGRESQL : ant -
...
- f data_build.
...
- xml db_metadata_run_total_count_postgresql
- ORACLE : ant -f data_build.
...
- xml db_metadata_run_total_count_oracle
- SQL SERVER : ant -f data_build.
...
- xml db_metadata_run_total_count_
...
- sqlserver
...
- Execute the RunTotalNum stored procedure on your database. This can take several hours. Example Example Usage:
...
Oracle:
begin
RUNTOTALNUM('observation_fact','i2b2demodata');
end;
...
Note:
...
If you get the error as: ERROR at line 1: ORA-01031: insufficient privilege, then run the command:
grant create table to (DB USER)
...
SQL server:
...
exec
...
RUNTOTALNUM
PostgreSQL:
...
select RUNTOTALNUM('observation_fact','public')
...
– (replace 'public' by the schema name for the fact table)
...
– If using a schema other than public for metadata, you might need to run "set search_path to 'i2b2metadata','public' " first as well
3.
- When finished, verify it is complete by checking that c_totalnum columns in your ontology tables contain numbers (not nulls).
These total counts will be counts will be visible in the ontology browser in the web client.

This will allow you to install the ACT ontology as a separate project in i2b2. Note that this will create a project with ONLY the ontology - no data. At this time, using the demodata with the ACT ontology is not supported. You will need to load your own data to run queries using the ontology.
- In the Release_1-7/NewInstall/Metadata/db.properties file change the db.project from demo to act
- Do the same in Release_1-7/NewInstall/Pmdata/db.properties, or perform these two steps manually:
- Create new Project ACT in the Admin tool
- Add AGG SERVICE Account to the Project
- The Hivedata install will add new dblookup-rows with parameters under CRC, Ontology and workplace to set up the project path, but this can also be configured manually in the Admin tool ( example as in below)
- Run the ant script against create_metadata_tables_release_1-7 and db_metadata_load_data.
This will create the new ACT Ontology structure under project ACT.

Warning Box |
---|
This is a community contributed feature, turned off by default, and has only been minimally tested by the core i2b2 team. |
An expanded set of lab flag values can be easily modified by users to support their needs or expanded to the full set of HL7/LOINC flag values. The expanded list is toggleable via an added config setting in the i2b2_ui_config.js. (Note: Only numeric lab results have the flag functionality included.)
With the expanded set of lab values, the base 'A','L','H' are omitted to prevent collisions with things like "CH" (Critical High) or "CL" (Critical Low) due to the indexOf
function call to determine if a flag is in the list.
To use the expanded lab flag set, make ETL changes to accommodate the expanded list of values you would like to use and modify i2b2_ui_config.js to match.
...
To set the webclient to start with the left pane in the new expanded mode, make sure this new parameter is added to i2b2_config.js.
startZoomed: true
The .zip file for this release defaults to this mode.

A new option is now available for loading Synthea data files into i2b2. Synthetic patient data generated by Synthea is hosted on SyntheticMass..The Synthea sample files have been converted to i2b2-ACT format. The zipped data files can be downloaded from https://github.com/i2b2/i2b2-synthea
Synthea Load Process:
- Create db Schema with name labeled synthea
- Load Synthea data from the sample data files provided
- Download the zipped flat files and extract to them to a local directory
- Using SSMS, import the sample obs file into obvseration_fact table
- Import the sample obs-pat file into patient dimension table.
- Download latest stored procedures from github
- Execute the stored procedures on your database to create the patientnum and encounternumbers.
