Data Standards
Organized by domains and subdomains often used in clinical studies, data standards include:
- CDEs — Classified as Core, Supplemental–Highly Recommended, Supplemental, or Exploratory
- CRF Modules — Template forms that logically organize CDEs for data collection
- Guidance Documents — Provide further information about the CDEs
- Instrument Notice of Copyright (NOC) Documents — Include pertinent information on recommended instruments (Instrument Notice of Copyright Information)

Overview
The National Institute of Neurological Disorders and Stroke (NINDS) formed the Stroke v1.0 CDE Working Group (WG) in July 2009. Chairs were appointed to lead the overall WG and the nine individual subgroups. The subgroups met regularly by teleconference in 2009 and 2010 to define the Common Data Elements (CDEs) for their domains and to recommend standardized, validated instruments for stroke research. The first set of CDEs for Stroke was completed in 2010.
NINDS formed an Oversight Committee (OC) to periodically review, direct the updating, and advance the development of Stroke CDEs in 2012.
In 2015, the Stroke OC reviewed the Core Stroke CDEs and determined needed classification updates based on disease stage and study type.
Based on the Stroke OC’s input, a Stroke v2.0 CDE Working Group was convened in 2018 to perform a comprehensive review of the Stroke CDEs. The WG was also asked to review the Unruptured Cerebral Aneurysms and Subarachnoid Hemorrhage (SAH) CDEs for inclusion and harmonization. The Stroke v2.0 CDE WG was divided into eight domain-specific subgroups:
- Stroke Presentation and Vital Signs
- Medical History and Prior Health Status
- Stroke Types and Subtypes
- Hospital Course and Acute Therapies
- Long Term Therapies
- Outcomes and Endpoints
- Imaging
- Biospecimens, Biomarkers, and Laboratory Tests
The Stroke v2.0 CDEs were posted in summer 2020.
The Stroke CDE Working Group and Oversight Committee are supported by the NINDS CDE Team.
