what is cdms
What is CDMS?
  • A clinical data management system or CDMS is used in clinical research to manage the data of a clinical trial
  • It is set up to help with processing data from source through validation checks, analysis, reporting and storage;
  • Also useful for Coding (particularly for AEs and Medications)
    • MEDRA (Medical Dictionary for Regulatory Activities)
    • WHOART (WHO Adverse Reactions Terminology)
institutional approach
Institutional Approach
  • Setting up a specific CDMS requires institutional decision making at policy level
  • Whatever the choice, it comes with a cost
  • Requires infrastructure and equipment set up
  • Requires minimum core competencies
  • Dedicated time for learning and development
  • Opportunities to try out
preferred software characteristics
Preferred Software characteristics
  • Standards based
  • Well known  many skilled practitioners available
  • Readily mastered and modified
  • Should run on any platform
  • Should be affordable for small groups in resource constrained countries
why an open source approach
Why an open source approach?
  • Potential advantages of Open Source solution
    • Cheaper
    • More amenable to change
    • No vendor lock in
    • More able to be integrated with other systems
    • Likely to be well documented
    • Designed to be multilingual
    • Open source software works eg R, Apache, MySQL
    • Used by major IT players eg Google, HP & IBM
    • Has been argued provides better software
      • saved the Human Genome Project according to Lincoln Stein
introducing open clinica
Introducing OpenClinica

Free, open source, web-based software for EDC built by Akaza Research

Features:

  • Management of diverse clinical studies through a unified interface
  • Clinical data entry and validation
  • Data extraction
  • Study oversight, auditing, and reporting
slide8

Submit data Module; Web-based Data entry and validation

Clinical Case Report Forms (CRF)

OC - DataBase

CRF Design, validation and import

Define CRFs in Excel Temp.

Creating Data Bases in OpenClinica

Designing a database in OC; requirement and flow of data.

slide9

Data Base Creating in OpenClinica

A part of CRF Excel Template: “Some tricks”.

slide10

Creating Databases in OpenClinica

Defining CRF on Excel Template

  • ITEM_NAME - This is the unique label or variable name for this data element.
  • DESCRIPTION_LABEL - give an explanation of the data element and the value(s) it captures.
  • UNITS - the units that the value of this data element should be captured in.
  • GROUP_LABEL - grouped items will display as a row within a table.
  • COLUMN_NUMBER - allow adjacent items or items with the same parent to be aligned together.
  • RESPONSE_OPTIONS_TEXT - list of the text values of the responses for this response set as a comma-delimited string.
  • RESPONSE_VALUES_OR_CALCULATIONS - comma-delimited list of the encoded values.
  • DATA_TYPE - data type; ST, INT, REAL, DATE.
  • VALIDATION - validation expression to run an edit check on this item
  • VALIDATION Expression - Expression Type:
  • 1) regexp - Supports Java-style regular expressions. regexp: /regular expression/ e.g regexp: /[A-Z]{3}/, requires a three-letter string (all uppercase)
  • 2) func - Supports built-in library of basic integer functions. func: func(args) e.g func: range(1, 10), func: eq(1), func: gte(10.5) etc.
slide11

The Back End of OpenClinica

  • Developed using Java J2EE framework
  • Application Server- Tomcat 5.x
  • Uses JDBC with JSP based front-end.
  • Database PostgreSQL 8.x or Oracle 10g
    • custom ports to DB2, SQL Server, or MySQL also possible
    • Has 74 related tables
slide12

Important Features of OpenClinica

  • Organization of clinical research by study protocol and site.
  • Dynamic generation of web-based CRFs in portable Excel templates.
  • Management of longitudinal data for recurring patient visits
  • Data import/export tools for migration of clinical datasets.
  • Interfaces for data query and retrieval across subjects, time, and clinical parameters
  • Compliance with regulatory guidelines e.g. 21 CFR Part 11
  • Built on robust and scalable technology infrastructure interoperable with relational databases
slide13

Designing CRFs

Done in excel using a blank CRF template provided by Openclinica

slide15

Uploading CRFs

The excel sheet is then uploaded onto OpenClinica

slide21

NAS1

Database

Database server

The Back Up Setting

  • Backups implemented via a scheduled command running as a batch file that writes out the data and metadata for each of the studies databases adding Timestamp information to the filename.

PgDump utility Creates a backup file on the secondary HDD on the main server. File automatically copied to NAS1

slide22

Restore Process

  • Installing Application Stack I.E. Postgresql, Apache Jarkata Tomcat,J2SE runtime environment and Deploying OpenClinica
  • Using a suitable Postgres database GUI(e.g. pgadmin III) create a new blank database on the database server
  • Run the pg_restore command on the server and select the backup file to restore
slide23

Deploying O/C for Multiple Sites

  • OC is deployed a as Openclinica.war file “Web Application archive“. It is a JAR(JAVA ARCHIVE) file used to distribute a collection of Java Server Pages, servlets, Java classes, XML files, tag libraries and static Web pages (HTML and related files) that together constitute a Web application.
  • Standard Installation Process is well documented inside an instructions file that ships with the application.
  • To deploy separate instances, rename the Openclinica.war to [studyname].war
  • Deploy as a normal OC application using the standard procedure and effect changes in database credentials inside the datainfo.properties of the deployed web Application.
slide24

Working with OpenClinica

  • Policy determination needed
  • Required human and material resources allocated
  • When know-how is established, utilization requires only 5 main steps:
    • Designing
    • Creating CRF’s
    • Event definitions
    • Data Entry
    • Data Extraction
slide25

GCP Regulations and OpenClinica

  • O/C by design, is compliant to the most stringent regulatory requirements
  • O/C is designed to be compliant to FDA 21 CFR Part 11-Electronic Records; Electronic Signatures
  • These are guidelines that govern the use of electronic records and signatures ; and can be summarized in two broad categories:
    • Technology best practice
    • Policy and procedures best practice
slide26

Technology Best Practices

  • Audit trail must be independently generated
  • Ensure that system maintains a “irrefutable link” between documents, metadata and the electronic signature.
  • Establish clear electronic signature manifestations for all electronic records.
  • Validate the system.
  • Establish role-based access and control.
  • Establish password and identification controls.
  • Series of signings.
  • Avoid hybrid systems, where practical.
  • Do not over customize technology solutions.
slide27

Policy & Procedures Best Practices

  • Establish corporate internal policies and guidelines for:
    • Validation and procedures
    • Disaster recovery
    • Revision and change control procedures
    • System access and security procedures
    • Training procedures
    • Document control procedures
  • Develop a clear, comprehensive migration strategy.
  • Understand the impact of “open” or “closed” system definitions.
  • Establish retention policies based on current predicate rule requirements.
