i2b2 Release 1.7.09

Release Date: June 16, 2017

1.7.09 Release Highlights

• Querying multiple observation fact tables
• Support for the OMOP Common Data Model (CDM)
• Minor bug fixes - see release notes for details

1.7.09 Release Summary

The standard i2b2 star schema only allows for one fact table, the observation_fact table. We have heard from the community there is a need to be able to search multiple fact tables with a single query. In release 1.7.09, the i2b2 has been updated to accommodate this growing need.

This new feature enables the i2b2 to adapt to the needs of the Patient Centered Outcome Research Institute (PCORI) network. It also supports the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM).

The i2b2 Community Wiki has additional information about multi-fact tables and i2b2 on OMOP. The following links will take you to their respective space on the wiki.

• Multi-fact table documentation
• i2b2 on OMOP project

A complete list of all the bug fixes and new features can be found in the Change Summary sections.

Improvement / New Feature Details

Multi-fact tables

As stated earlier the standard i2b2 star schema only allows for one fact table, however [CORE-240] enables the crc to query multiple fact tables.

The setup is fairly simple; In the crc.properties file you will find a new parameter called queryprocessor.multifacttable, and when this parameter is set to true the crc will query all the fact tables you have setup.

The parameter is delivered with the value set to false, which means the multi-fact table feature is turned off and the CRC will behave as it has always done (prior to this release).

Custom Value Choosing Handling

We are working on re-developing the way the lab value chooser works in the web client. The new implementation will allow for custom lab value handling in a modularized way. WEBCLIENT-206 is laying the ground work for this re-design. Users will not notice a difference on how they select lab values.

i2b2 Release 1.7.08

Release Date: October 7, 2016

1.7.08 Release Summary

Release 1.7.08 contains a number of new features as well as bug fixes. Below are a few highlights of the changes included in this release. Information about the other changes can be found in the sections that follow this one.

JBoss Updated to WildFly

In order to address some of the security vulnerabilities that exist in some JBoss installations, the i2b2 Server has been upgraded to use WildFly. In 2014 Red Hat renamed their JBoss Application Server to WildFly and their latest version (WildFly 10) addresses the known security vulnerabilities.

SQL Server: Option to Improve Query Performance

New parameter to use temp table constraint instead of 'WITH' clause.

Large data warehouses that contain broad and deep ontologies run the risk of CRC queries having a slow response time. In this release (1.7.08) a new parameter has been added to the crc.properties file. This new parameter allows a site to use a temp table instead of a 'WITH' clause when running a CRC query.

Additional information about this new feature can be found in the Improvement / New Feature Details section under the SQL Server: Option to Improve Query Performance heading.

Improvements to the Processing of Queueing Queries

In the Previous Query display, new statuses provide users with additional information that accurately reflects the current status and location of the query. The new statuses are:

• SMALL_QUEUE
• SMALL_QUEUE_RUNNING
• MEDIUM_QUEUE
• MEDIUM_QUEUE_RUNNING
• LARGE_QUEUE
• LARGE_QUEUE_RUNNING

In addition to updating the status of queries, an additional feature was added to the Web Client that makes these statuses visible to users. The query status can be seen in Previous Queries as well as in Show Query Status.

A complete list of all the statuses as well as additional information about this new feature can be found in the Improvement / New Feature Details section under the Improvements to the Processing of Queueing Queries heading.

Improvement / New Feature Details

View and Update the DB_LOOKUP Tables

JIRA ISSUES:
      [CORE-218] - New web service to retrieve the db lookup settings in the configuration files
      [WEBCLIENT-191] - ADMIN: Add the ability to view DB_LOOKUP settings for each cell

Release 1.7.08 added the ability to view current database connections defined in the DB_LOOKUP tables for each i2b2 cells. Administrators can also edit existing values and add new entries into the tables. This new feature resides within the i2b2 Admin Module. The DB_LOOKUP tables are specific to each i2b2 cell. To access the list of values in a specific cell you need to expand Manage Cells in the Navigation Tree on the left of the page. Then select the cell to expand further, once this is done you will see DB-Lookup as an option. Clicking on DB-Lookup will display the DBLookup List page. This page will display all the values in a table format.

The following screen shot shows all the entries in the CRC_DB_LOOKUP table.

To add a new entry into the DB_LOOKUP table simply click on the Add New DBLookup button that appears above the table of existing values. The page will be updated to a form with fields to capture the information to be stored in the DB_LOOKUP table.

To edit an existing entry, click on its Name located in the Navigation Tree on the left. The page will be updated to show the values currently filed in the DB_LOOKUP table. Make any changes and click on Save to save your edits.

Improvements to the Processing of Queueing Queries

JIRA ISSUES:
      [CORE-221] - Improvements to the queuing process when running a query
      [WEBCLIENT-192] - Improvements to queued queries in status window

In the i2b2, there are three queues a query may be placed into when it is run. The length of time a query waits in each queue is defined in the crc.properties file.

1. Small Queue
2. Medium Queue
3. Large Queue

In the Web Client, the status of a query can be seen in Previous Queries. The status would be PROCESSING, ERROR, or COMPLETED. None of these statuses would provide information on which queue the query was in. Database administrators would have to view the query in the QT_QUERY_INSTANCE table to see the queue information. The statuses and queue information were often ambiguous which would make it challenging to trouble shoot any issues.

To address this issue, new statuses have been added in Release 1.7.08. These new statuses provide users with additional information that accurately reflects the current status and location of the query. The new statuses are:

QUEUED ERROR COMPLETED PROCESSING SMALL_QUEUE MEDIUM_QUEUE LARGE_QUEUE MEDIUM_QUEUE_RUNNING LARGE_QUEUE_RUNNING RUNNING

In addition to updating the status of queries, an additional feature was added to the Web Client that makes these statuses visible to users. The query status can be seen in Previous Queries as well as in Show Query Status.

SQL Server: Option to Improve Query Performance

JIRA ISSUES: [CORE-226] - New parameter to use temp table constraint instead of 'WITH' clause

Large data warehouses that contain broad and deep ontologies run the risk of CRC queries having a slow response time. In this release (1.7.08) a new parameter has been added to the crc.properties file. This new parameter allows a site to use a temp table instead of a 'WITH' clause when running a CRC query. In some environments, using a temp table allows the query to run more efficiently and process the request faster.

Parameter Name: edu.harvard.i2b2.crc.setfinderquery.constraintlogic
Located in: crc.properties file
Behavior:

If the parameter is missing from the crc.properties file, the system will current query logic (WITH clause).

Date Constraint Improvements

JIRA ISSUES: [WEBCLIENT-133] - Restrict ability to add Date Constraint if a panel contains any age concepts.

In the i2b2, the CRC will use the START_DATE in the OBSERVATION_FACT table when running a query with a date constraint defined on a panel. This can present a problem if at least one of the items in the panel is an age concept and the patient demographics are stored in the PATIENT_DIMENSION table. The problem is ages that are stored in the PATIENT_DIMENSION table will not have a START_DATE and therefore the date constraint is not valid.

General i2b2 users do not know whether or not an age has a start date and if they select a date constraint their query may not return the expected results. This becomes a bigger issue when you are using the i2b2 in a larger network in which some sites may store it in the PATIENT_DIMENSION and others in the OBSERVATION_FACT. This scenario will definitely result in misleading results and the user will be unaware of the discrepancy.

To avoid any confusion or misleading results, users can no longer add a date constraint if at least one item in the panel is an age concept. The following message will appear when attempting to set a date constraint on a panel with an age concept: Date constraints are not allowed for age related concepts. This panel contains at least one age related concepts, therefore a date constraint can not be set for this panel."

Web Client Configurations

JIRA ISSUES: [ WEBCLIENT-198] - Parameters/Configurations for Web Client

In Release 1.7.08, a new configuration file has been added to the i2b2 Web Client. This file allows site administrators to customize the text on the login screens, default user id and password values, as well as how obfuscated results display in the i2b2 Web Client.

       File Name: i2b2_ui_config.js        File Location: /webclient/js-i2b2/

SQL Server: New Connection Parameter to Pass in String Based Variables

JIRA ISSUES: [CORE-227] - Add ability to send parameters with string based variables as varchar instead of nvarchar

Prior to release 1.7.08, parameters are sent in as Unicode (nvarchar) instead of varchar. SQL Server then has to explicitly convert the nvarchar to varchar in the query. The effect is that SQL Server optimizer may have to use an index scan instead of an index seek (which is faster).

To address this issue, we have added a new connection parameter to be used when i2b2 uses PreparedStatements to pass in string based variables in SQL Server. The following connection parameter is to be added to the datasource definition.

Connection Parameter: connection-property name="sendStringParametersAsUnicode"
Added To: datasource definition
Behavior:

Example:        <connection-property name="sendStringParametersAsUnicode" >false</connection-property>

Updated JDBC Drivers

JIRA ISSUES: [CORE-229] - Provide updated JDBC drivers used by Oracle, PostgreSQL, and SQL Server

Included in release 1.7.08 are updated JDBC drivers for Oracle, PostgreSQL and SQL Server. The new version of JDBC drivers are optional and will not be installed automatically.

Information on Updating Drivers

This section contains some general information and key points to keep in mind when updating your JDBC drivers.

Location of JDBC Jar files

Your current JDBC jar files reside in the following directories:

1. ${jboss.home}/standalone/deployments/${axis2.war.name}/WEB-INF/lib
2. ${jboss.home}/standalone/deployments

New Version of JDBC

There are three new jar files, one for each type of supported databases.

1. Oracle = ojdbc7.jar
2. PostgreSQL = postgresql-9.4-1209.jar
3. SQL Server = sqljdbc42.jar

Update Existing i2b2 Instance

A script to deploy the new jar files has been included in the 1.7.08 Release. Once you have updated your server with the latest code you can run one of the following commands to deploy the new jdbc jar files:

Improvement / New Feature Details

Edit tool to file C_PATH and C_SYMBOL when adding new item

JIRA ISSUES: [CORE-135]

In the i2b2 metadata table there are two columns (C_PATH and C_SYMBOL) that are used exclusively by the Ontology Mapping tool. Prior to release 1.7.03 these columns were not populated when you added a new term via the Edit Terms view. This situation has been rectified in that these columns will now be populated with the appropriate data when creating a new container, folder, term, or modifier from within the Edit Terms view.

Edit Tool view: Line feeds removed from Metadataxml

JIRA ISSUES: [CORE-141]

In the Edit Terms view users can create terms that have values associated to them. These values are stored in the C_METADATAXML column in the custom metadata table. Prior to release 1.7.03 when you created or edited a term with values in the Edit Tool view, the metadata was stored in the table with carriage returns / line feeds. This change improves the way the metadataxml if filed into the table by removing all line feeds from the data before filing it into the C_METADATAXML column

Improvement / New Feature Details

Password Management

JIRA ISSUES: [CORE-95] and [WEBCLIENT-56]

In release 1.7.02, i2b2 users are now able to change their password from within the i2b2 Web Client and Workbench. Previously to this release, users did not have the ability to change their own password. They would have to notify their administrator who would have to change it for them in the i2b2 administration module. This new feature adds a layer of security in that the user can manage their own password and not have the added risk of other users (i.e. the admin) knowing their password.

In the i2b2 Web Client, a new option called Change Password now appears in the Web Client's toolbar.

Clicking on Change Password will open the i2b2 Change Password window.

In the i2b2 Workbench, a new button labeled Password has been added to the i2b2 desktop title bar.

Clicking on Password will open the Set Password window.

The functionality to change your password is the same regardless of whether you access the change password window from within the i2b2 Web Client or the workbench. There are basically three steps:

1. Enter your current password.
2. Enter a new password for your user.
3. Retype your password.

Once you do the above three steps and click on OK the system will verify you entered your "current" password correctly and the password you entered at the New Password and Retype Password fields match. Provided everything is correct your new password will be saved.

Improvement / New Feature Details

Temporal Queries

The temporal query is a new type of query introduced in release 1.7. There are two components to these queries that make them a little more complex than the type of queries available prior to 1.7 (classic i2b2 queries).

The first component to these queries is the list of events defined by the user.

The second component is the relationship between the events. This relationship is referred to a Temporal Relationship, which is best described as how the different events relate in regards to the time in which the event(s) occurred.

Users can also define a patient or event population in which they wish to run the temporal query against. This step is optional and is not required in order to run the temporal query.

The process in which temporal queries are defined is slightly different in the i2b2 Web Client and the i2b2 Workbench. In the i2b2 Web Client the existing Query Tool view has been modified to accommodate Temporal Queries while a new view called Temporal Query Tool view has been created for the i2b2 Workbench.

The new Temporal Query Tool view and the modifications to the existing Query Tool view extend the query functionalities provided by the classic Query Tool view.

It is important to note that while the manner in which users setup a temporal query is different in each of the clients the overall functionality is the same.

The following two sections will describe how to run Temporal Queries in the i2b2 Web Client and the i2b2 Workbench.

i2b2 Web Client: Temporal Queries

In the i2b2 Web Client there are five basic steps in defining a temporal query in the Query Tool view.

1. Change Temporal Constraint to Define sequence of Events.
2. Define Population in which events occur (optional step).
3. Define Events
4. Define order of events (temporal relationships)
5. Run the query

Step 1: Change Temporal Constraint

The first step is to change the Temporal Constraint to Define sequence of Events.

Step 2: Define Population in which events occur

Once you have changed the Temporal constraint to be Define sequence of Events a new Page selection box will appear below the Temporal Constraint section. The default page will be Population in which events occur. It is on this page you will define your population requirements.

Step 3: Define Events

The events are the first component of a temporal query. There are no restrictions on the number of events you wish to define. The only requirement is that you have to define at least two events.

To define the events simply click on the Page selection box and select Event 1 from the drop-down list.

The groups and constraints for the events work in the same manner as they did for a traditional i2b2 query. Simply drag the items you want to include in Event 1 to the appropriate groups.

Once you have added your items to the groups you can click on the Page selection box and select Event 2 from the drop-down list. This will change the page to display the groups for Event 2.

If you need to add a third event you can click on the New Event button located next to the Page selection box.

Step 4: Define Order of Events (Temporal Relationship)

As stated earlier the second component of a temporal query is the relationship between the events (temporal relationship). In the i2b2 Web Client this is done on the Define order of events page, which is accessed by clicking on the Page selection box and selecting Define order of events from the drop-down list.

The page will display as follows:

Step 5: Run Query

In the Web Client running a query works the same regardless of whether or not it is a Temporal Query or a traditional i2b2 query. By clickin on the Run Query button, the i2b2 client will send the request to the i2b2 server which will run the query as defined.

i2b2 Workbench: New Temporal Query Tool View

In the i2b2 Workbench there are three pages or steps in defining and running a temporal query in the new Temporal Query Tool view.

1. Page 1: Define Population
2. Page 2: Define Temporal Relationships
3. Page 3: Review and Submit Query

i2b2 Workbench: New Temporal Query Tool View

Define Date Constraints and Exclusions in Temporal Query Tool View

Defining the Date Constraints

Exclude Panel

Each page as well as defining constraints is further defined in the next few sections.

Page 1: Define Population

On this page you will define your population requirements.

Page 2: Define Temporal Relationships

As stated earlier there are two components to a temporal query; (1) List of events and (2) the relationship between the events.

The second page is where you will define both the events and their relationship.

Page 3: Review and Submit

On this page the name of the query will default and if you wish to rename it you can do so at this point. Whatever is entered here will be the name given to the query when it is run. In addition you can select the Analysis Types that you want when running the query.

Defining Date Constraints and Exclusions in Temporal Query Tool View

There are some minor differences in terminology or layout that needs to be noted in this release note.

Defining the Date Constraints

In the classic Query Tool view you can only define date constraints on the group / panel level. In the new Temporal Query TOol view you can now define a date constraint on either the query or group levels. If you define it on the query level it will default the same date constraint for all the groups and the date constraint on the panel level will not be available for selection.

If you want to define it on the panel level select Group-Specific. Go to the group you wish to define the constraint and click on the column that displays No Date Constraints.

Exclude Panel

The ability to exclude all items in a group does exist in the new Temporal Query Tool view. However, the method in which it is defined differs between the classic Query Tool view and the Temporal Query Tool view.

In the existing Query Tool view ("Classic") the exclusion constraint was defined by clicking on the button labeled Exclude.

In the Temporal Query Tool view (New) the exclusion constraint was rolled into the window for defining the Occurrence constraint.

The Specify Occurrence Constraints windows will open when you click on the box that displays the occurrence constraint. To set the exclusion constraint you need to select "= 0 (No Occurrences)" from the drop-down list.

The above option is equivalent to the Exclude feature in the classic Query Tool view.

Previous Query: Filter list by user

New in release 1.7 is the ability to filter the list of previous queries by the user who created the query. In the options dialog () window there is a new field called Get previous queries for user. The default is all users and can be changed to a specific user by clicking on the down arrow to display the drop-down list. Once you select the user and click on OK, the Previous Queries view will refresh and display only those previous queries created by the selected user.

Previous Query: Search Previous Queries View

In release 1.7 the ability to search the Previous Queries view has been added. The functionality is very similar to Find Terms view except it will search the Previous Queries view instead of Navigate Terms view. Users can search any of the three levels;

1. Previous Query (name)
2. Previous Query Result
3. Patient

Previous Query: Page through previous queries by date

Users can now retrieve the next or previous grouping of previous queries by the date in which the query was created.

The Previous button () will retrieve the group of previous queries that occur prior to the date displayed in the date / time field.

The Next button () will retrieve the group of previous queries that occur after the date displayed in the date / time field.

Identity Management Cell (IM)

A new cell called the Identity Management (IM) Cell was developed in release 1.7. This new cell contains Protected Health Information (PHI), which can be used to identify patients. The IM cell is used to manage this PHI in a manner consistent with the HIPAA privacy rule. The patient data will be available only as a HIPAA defined "Limited Data Set" to most of the hive.

The full functionality of the IM cell will be developed in stages. The initial framework and key services are released as part of the 1.7 release. Some of the key features being released in 1.7 are:

1. New tables to store identifiers from different sites, and patients that are included in a project.
2. Audit controls are implemented that are in compliance with the HIPAA privacy rules.
3. Services developed to set and validated an AES key for encrypting and decrypting patient MRNs in the IM cell.
4. Unencrypted patient identifiers sent in the PDO can be processed through the IM cell to retrieve all site IDs for the patient and project.

In addition to the above features, the i2b2 Worbench (eclipse client) has two new views that were created to support the new IM cell. These new views, called Patient Mapping and Admin Tool are further defined in the following two sections called Patient Mapping View and Admin Tool View.

Managers Tool View

The Managers Tool view was developed in release 1.7 and works in conjunction with the IM Cell. It currently has two main functions.

1. Set and / or validate that the project key is defined in the IM Cell.
• The project key is used by the IM cell to decrypte the patient id"s that are encrypted.
• The Set Key is used to define the key in the IM cell.
• The Validate Key is used to verify the key is set.

Important If you are using the IM cell and your patient identifiers are encyrpted the you need to set the Project key in the IM cell. It is important to note that if you restart your i2b2 server or in the case of the VM image restarting the virtual machine then you will need to re-enter the project key. The project key for the i2b2 demo project is: i2b2demodatakey1 In the VM image you need to log into the i2b2 Workbench as the i2b2 Admin user. User ID: i2b2 Password: demouser

2. View the audit information.
• As part of the IM cell an audit table was created to track when a patient in the IM cell was accessed. This new view allows Project Managers or Administrators to run a report to see that audit information. The report can be run for a particular user, patient, or all audit information for the project you are logged into.

Patient Sets View

In release 1.7 a new view called Patient Sets was created. This new view will display a list of Patient sets that were created when a query was run. It is similar to the Previous Queries view except it only displays the patient sets and not the previous query or other result sets (i.e. Encounter sets, Number of patients, etc).

The patient sets can be expanded to display a list of patients.

Users can drag an entire patient set or a single patient to other views in the i2b2 Workbench.

Users can also perform a search in which they can search by the name of the patient set or for a list of patient sets that contain a specific patient.

Workplace Find View

A new view called Find in Workplace was created in release 1.7. This view is very similar to the Find Terms view except it will search the Workplace view instead of the Navigate Terms view.

Find Terms: New feature called "Jump to Term in Tree"

A new feature called Jump to Term in Tree has been added to the Find Terms view. Users can now easily jump directly to a term in the Navigate Terms view from the Find Terms view.

Once a term is found in the Find Terms view the user can click on the term using the right mouse button to display the pop-up menu. Selecting "Jump to Term in Tree" from the pop-up menu will bring the Navigate Terms view into focus and the hierarchical tree will automatically open to the location of the term selected in the Find Terms view.

OpenEMPISupport

OpenEMPI is an open source Enterprise Master Patient Index (EMPI) which is developed and supported by another community. The i2b2 IM cell has been developed to allow communication with OpenEMPI for those sites that choose to use it as their patient repository.

For additional information on OpenEMPI please see their website by going to the following location: https://openempi.kenai.com/

PostgreSQL Database Support

The ability to use a PostgreSQL database as an i2b2 database has been added to release 1.7. Both the create and insert data database scripts for PostgreSQL are included in this release.

Data: New Tables created for the IM Cell

The following new tables were created as part of the new IM cell.

Data: New Columns added to support IM cell

A new column called Project_ID has been added to both the PATIENT_MAPPING and ENCOUNTER_MAPPING tables in the crc. The PROJECT_ID was added to support the IM cell. It will allow sites to track which project a patient is part of.

Data: Improved Patient Mapping Data

The PATIENT_MAPPING table in the CRC has been updated to include the following:

• Mappings of existing patients to multiple site MRNs.
• Project IDs added to patients.

Demo data has been added to all of the new IM tables except the AUDIT table. This IM data was added to provide examples for using the new IM cell.

New PostgreSQL Database Scripts

The i2b2 database scripts have been updated to include the table creation and data insert scripts for a PostgreSQL database.
