2. CLINICAL DATA MANAGEMENT
INTRODUCTION:
Clinical Data Management is involved in all aspects of processing the clinical data, working with a range of
computer applications, and database systems to support the collection, cleaning, and management of subject or
trial data.
Data Management in clinical research relates to the processes of gathering, capturing, monitoring, analyzing,
and reporting on data.
Data management begins with the development of the data management plan and design of the data capture
instrument (e.g. the case report form), continues with data collection and regular quality control procedures,
the database cleaning, locking, and ends with the analysis, archiving and write-up.
3. IMPORTANCE OF CDM
• The objectives of good clinical data management are
to ensure that the study database is: An accurate and
true representation of what took place in the study
and sufficiently clean to support the statistical
analysis and its interpretation.
• Review & approval of new drugs by Regulatory
Agencies is dependent upon a trust that clinical trials
data presented are of sufficient integrity to ensure
confidence in results & conclusions presented by a
pharmaceutical company.
• Important to obtaining that trust is adherence to
quality standards & practices.
• Hence, companies must assure that all staff involved
in the clinical research are trained & qualified to
perform data management tasks.

TRIAL
Regulatory submission
Analyse & Clinical study report
Database lock
Data review & Discrepancy Management
Data entry
CRF scanning & Indexing
Data collection
Conduct of the data
Data Management Plan:
DMP should give a complete picture of how the
data will be handled throughout the study by
outlining all the information relating to the
study's data management procedures.
It should include:
• database structure specifications
• A description of the database building and
testing procedures
• A list of SOPs foe the data management
process which will be used to ensure
consistency
• A description of how the data will be
reviewed and information about how changes
in data will be managed.
• details of how the data will be coded,
analyzed and achieved.

Database designing:
• Plan the way the data is to be
structured
• Data sets defined and coded with
alphanumeric codes
• These codes are annotated to the
blank CRF
• Based on the protocol requirements
the validation rules are created
• A validation plan is written and
reviewed by the QC group ad the
Statistician

7. DATA REVIEW AND VALIDATION
• Data cleaning or validation refers to a collection of activities by data management,
used to assure validity and accuracy of the clinical data.
• It comprises both logical and statistical checks to detect impossible values due to data
entry errors, coding, and inconsistent data.
• Point-by-point check
• Missing data/blank field checks
• Data consistency checks
• Lab data range checks
• Header inconsistency checks
• Protocol violation checks
• External data checks
• Textual data checks
• SAE reconciliation

9. WHY TECHNOLOGY
IN CDM
• More automation reduces
manual input
• Allows processes to be linked
• Increases processing speed
• Stores large volumes of data
• Enables global studies
• Automates tracking of
processes
• Eliminates/ simplifies steps
in the process
• Reduces chance of human
error
