OpenClinica 3.1 is Finally Here!

After nearly 20 months, OpenClinica 3.1 is finally ready to meet the world as a production ready application.  You may download OpenClinica 3.1 here.  It has been a long and arduous road, but the final incarnation of 3.1 is the most significant leap forward for the OpenClinica clinical trials software.

OpenClinica 3.1 further accelerates clinical productivity and enhances the clinical trial experience in a number of notable ways:

  • Improved data entry save time and increased performance for accessing large amounts of data.  The architecture around the data entry process in OpenClinica was re-factored to allow more concurrent users accessing the system while conducting more intensive simultaneous processes.  With this re-factoring, page turn times have seen a 10x (and sometimes better) speed improvement.  At the same time, large extracts which had to be broken into smaller subsets in the past can now be executed in a single batch.
  • Skip logic to ensure data entry users only see CRF fields and sections relevant to entering their data.  When a user accesses an eCRF to enter data for a patient or subject, they will only see the fields pertinent to be collected at that time.  Logic can be built in to the eCRF to show or hide additional fields based on the values provided in previous questions.
  • Streamlined discrepancy and query management infrastructure that allows issues around questionable data to be resolved more quickly.  A new interface for creating and responding to discrepancies, as well as new filters for query aging, to support faster resolution of data issues.  The number of clicks for filtering/sorting discrepancy notes, viewing the data responsible for the discrepancy note, and returned back to your filtered set of reports has been cut in half.
  • GUI-based creation, testing, and management of complex cross field/cross form multivariate edit checks.  A simple drag and drop interface has been implemented to facilitate the faster creation of complex edit checks.  This new interface interacts with authorized OpenClinica instances to speed up the study design process for OpenClinica Enterprise edition clients.
  • Plug-in architecture for exporting data collected in OpenClinica which supports the transformation of data into any output format.
  • OpenClinica Data Mart to easily report clinical trial results collected through OpenClinica.

These last two items have been covered extensively in previous blog posts.  Please see Plug-in Architecture for OpenClinica Data Extracts and Video Demo of New OpenClinica Data Mart.

We will be hosting an OpenClinica Community Virtual Forum shortly to demonstrate some of these new capabilities.  Also, keep this blog on your RSS feed or bookmarked in your browser, as future posts will dive into more details of the new features and functionality in OpenClinica 3.1.

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.
