National Institute of Neurological Disorders and Stroke Common Data Element Project - approach and methods

Area of Science:

• Neuroscience Clinical Research
• Data Standards Development
• Biomedical Informatics

Background:

• Neuroscience clinical research requires significant effort in data collection and management.
• Inconsistent data definitions and formats hinder data aggregation and meta-analyses across studies.
• Investigators funded by NINDS are often mandated to share data, facing challenges due to data heterogeneity.

Purpose of the Study:

• To assist neuroscience clinical researchers by developing standardized data collection tools.
• To accelerate data sharing and improve data aggregation across the research community.
• To enable systematic data collection through the NINDS Common Data Element (CDE) Project.

Main Methods:

• A systematic and iterative approach was employed by the NINDS CDE Team.
• The development process incorporated community involvement and a structured decision-making framework.
• A dedicated technical support team was established to aid CDE development.

Main Results:

• The NINDS CDE Project website (http://www.commondataelements.ninds.nih.gov/) now hosts critical core and disease-specific CDEs.
• The website provides tools to facilitate systematic data collection and study start-up.
• Additional disease-specific CDEs will be added following development and vetting.

Conclusions:

• The continued evolution and improvement of CDEs depend on active use and feedback from clinical researchers.
• NINDS strongly encourages its grantees to adopt CDEs and is enhancing educational efforts.
• Version 1.0 of the CDEs has been published, with ongoing annual evaluation and revision to ensure relevance.
