OpenClinica 3.1 Release Update

We are in the final development stretch of the OpenClinica 3.1 project.  Over the course of alphas and betas some items have been inevitably been added, removed, and changed, so I thought it would be useful to provide an up-to-date list of features and bugs that are being addressed in this release.

Those of you attending the OpenClinica Global Conference May 8-9 here in Boston will get to experience numerous demonstrations of 3.1 functionality, and of course get to interact directly with members of our rockstar development team 🙂

First, here’s a quick review of some of the more popular new features:

  • Dynamic items in a CRF
    • Supports showing and hiding of items based on values provided in a separate field
    • Supports insertion of data across fields and CRFs based on values provided in a separate field.
  • Re-factoring of the Extract Data module to support custom data transformations allowing you to extract data in essentially any conceivable format.
  • Improved capabilities for sharing data entry duties among a given site’s users
  • Discrepancy Note “Days Open” filter to better monitor discrepancy aging
  • Discrepancy Note “Days Since Updated” filter to ensure productive discrepancy resolution
  • Audit log and discrepancy note data included in ODM exports
  • Improved CRF page turn time (in many cases over 10x faster)
  • CRF Header updates to provide a cleaner data entry experience
  • Ability to assign Failed Validation Checks (in addition to Queries)
  • Relative Paths for Item OIDs in Rules to enable portability and reusability of Rules
  • Discrepancy Note flag colors now appear in the CRF
  • Additional study parameter configuration options to opt out of using certain fields such as Interviewer Name, Interview Date, and Location
  • OpenClinica Datamart for ad-hoc reporting (Enterprise only)
  • GUI Based, drag-and-drop Rule Designer (Enterprise only)

More detailed descriptions of the above features can be found in the previous blog posts “OpenClinica 3.1 (project “Amethyst”) Preview” and “New Capabilities Added to OpenClinica Version 3.1.”

For those sufficiently ambitious, yes, you can see a complete list of ALL the 457 separate enhancements and bug fixes in 3.1 as of April 6, on the OpenClinica Amethyst Project Roadmap.

And finally, here’s the current release timeline:

  • Beta 4 released week of April 11th
  • Release Candidate 1 released week of April 18th
  • Production Release of OpenClinica 3.1 early May.

Many thanks to the dedicated team of folks who, for the past 19 months, have worked tirelessly to make this the most significant OpenClinica release ever.

New Capabilities Added to OpenClinica Version 3.1

For the past 12 months, the OpenClinica development team has been working diligently on the next major OpenClinica release. In a prior blog post (OpenClinica 3.1 (project “Amethyst”) Preview), I discussed some of the new functionality and key improvements this forthcoming release will include. Since then, the development team has added some more pieces of functionality, most notably:

  • Re-factoring of Extract Data to enable custom data transformations
  • Discrepancy Note “Days Open” filter
  • Discrepancy Note “Days Since Updated” filter
  • CRF Header updates
  • Additional study parameter configuration options
    • Interviewer Name – not used
    • Interview Date – not used
    • Location – not used
  • OpenClinica Data Mart for ad hoc reporting*
  • GUI-based Rules designer*

Custom Data Transformations

From a development perspective, perhaps the most significant piece of functionality in the above list is the complete re-factoring of the Extract Data module. In prior versions of OpenClinica, the Extract Data module would natively export CDISC ODM 1.2, CDISC ODM 1.3, both ODM 1.2 and 1.3 with OpenClinica extensions, tab-delimited text, and an SPSS file format. While these formats will continue to be available in 3.1, OpenClinica will have the ability to process (via XSL style sheets) any CDISC ODM 1.3 data set into any other data format.

This new XSL method of extracting data from OpenClinica opens up a new world of formats in which data may be obtained from OpenClinica. To create a new extract format, all one has to do is configure a new XSL style sheet. Organizations can write their own XSL style sheets then configure a file called extract.properties that allows OpenClinica’s XSL transformation engine to convert the data in the ODM XML file into the organization’s desired format.

GUI-based Rules Designer*

The GUI-based Rules designer is a project currently underway that allows users to build cross-field/cross-form multivariate edit checks without having to interface directly with XML. Its intuitive, drag and drop interface hides much of the current complexity in creating and managing Rules, while retaining the system’s robust capabilities in this area. Users will be able to work directly with the Item Names as defined in a CRFs definition, eliminating the need to keep track of OIDs.

OpenClinica Data Mart*

The OpenClinica Data Mart presents clinical data from OpenClinica studies in a readily-accessible relational database for ad hoc reporting and analysis. The Data Mart enables data managers, project managers, and researchers to create reports and mine data using standard business intelligence software or SQL reporting tools

Beta Timeframe

We currently expect the first Beta of 3.1 to be available towards the end of November. This Beta will be feature complete, and blocking issues that prevent the testing of new features will have been resolved. Once the first Beta is released, we will begin the 3.1 Pilot Program. We currently have 10 organizations participating in the Pilot Program, but if your organization would like to volunteer as well please contact me.

Please be sure to check back the OpenClinica Blog often as I post future updates on the 3.1 timelines.

OpenClinica 3.0.1 Features Improved CRF Save Times

Akaza Research will be releasing a maintenance update of OpenClinica 3.0, which by itself probably does not illicit much excitement.  Usually maintenance releases only fix small bugs and offer little noticeable improvements to a user’s overall experience.  However,  3.0.1 will offer a dramatic improvement for a user’s experience with regards to the amount of time it takes Rules to run on a CRF.

Users of previous versions of OpenClinica would reach pain points when trying to save data entered onto certain CRFs if the study build had applied very complex Rules on a particular CRF section. For example, if the system had to check more than 10 variables to ensure one particular field had accurate data, the user might experience a save time of 2 or even 3 minutes in some circumstances.  In a test environment, we were actually able to create a scenario where the CRF save time took 19 minutes!

As part of 3.0.1, among other things, we have dramatically improved the save time of a CRF with complex Rules.  For instance, in the extreme scenario utilized in our test environment, we were able to cut the save time from 19 minutes down to 10 seconds.  That is about a 11,400% improvement!  For more typical users who were experiencing 2 or 3 minute save times, this has been cut to 3-5 seconds.

We are committed to improving the performance of OpenClinica, and can even offer faster experiences to the users of the OpenClinica Enterprise Edition.  Please see our website for the differences between the Enterprise and Community versions of OpenClinica.

OpenClinica 3.0.1 will be out next week!

OpenClinica 2.5 Release

We are getting very near to the release version 2.5 of OpenClinica, representing a major milestone in the development of the popular open source software for electronic data capture (EDC) and clinical data management. The release contains a number of exciting improvements, including:

–    Rules engine for executing cross-field or cross-form edit checks and triggering notifications to users
–    Scoring calculations (derived values) in case report forms (CRFs)
–    New user roles for monitors and data managers
–    Improved monitoring/query management tools and discrepancy note reporting
–    Electronic signature capabilities
–    Ability to copy and edit previously created datasets
–    Improved auditing and logging capabilities
–    Simpler CRF upload
–    Improved support for CDISC ODM v1.3
–    Support for Oracle DB Backend out of the box.
–    Minor UI and application fixes from OpenClinica 2.2
–    Improved performance and scalability

Over the past 6 weeks the core development team has been putting OpenClinica through a rigorous, validated, QA and testing procedure. There are roughly another 3 weeks of documented testing ahead of us. If you would like to try the latest beta version of the application, please download it from http://svn.akazaresearch.com/OpenClinica-2.5-distros/.

Thanks to everyone in the community who has contributed to this release and provided feedback during the alpha and beta periods!

As we get closer and closer to the production release of OpenClinica 2.5, stayed tuned to this space for additional updates.
