Preclinical Common Data Elements

At this time, the FITBIR informatics platform is limited to housing research data on Traumatic Brain Injury (TBI) studies related to human subjects. FITBIR is not housing preclinical research data related to non-human subjects. Preclinical TBI researchers are referred to utilize the interagency resource center known as PRE Clinical Interagency reSearch resourcE-TBI (PRECISE-TBI) center and to house their data in the Open Data Commons – Traumatic Brain Injury (ODC-TBI) repository.

In partnership with the Department of Defense (DoD), the National Institute of Neurological Diseases and Stroke (NINDS) has led efforts to develop standards for preclinical research data in TBI. Experts in preclinical TBI research from academia were invited to participate in TBI Preclinical Working Groups with the goal of developing TBI common data elements (CDEs) for preclinical research and to establish guidance for the utilization of preclinical CDEs in TBI research. The outcomes of these working groups have been reported by Smith et al. 2015 and LaPlaca et al. 2021  and additional details are archived below. NINDS is continuing to lead these efforts for preclinical CDE development and refinement in partnership with the DoD and Veterans Affairs (VA) through the VA-funded interagency resource center PRECISE-TBI.

The primary objective for developing preclinical CDEs is to produce a well-defined lexicon for describing and reporting how preclinical data are collected with the goal of enhancing rigor, reproducibility and transparency in study performance. The goal of CDEs is to develop a tool to improve standardization of data collection such that experimental details and procedures are reported in a standard transparent manner that allows for rigor and reproducibility. Additionally, it is important for data to be collected, reported and curated in a standardized manner and format that will allow TBI researchers to share data across sites and reuse data for either secondary analyses or big data analyses.

OVERVIEW of 2016-2019 Traumatic Brain Injury Preclinical Working Group

As such, the working groups (WGs) were asked to determine the level of experimental detail that should be reported in order to improve inter-investigator data harmonization.

The TBI Preclinical Working Groups intended to address the challenge that, while well-validated and standardized animal models of TBI can enhance our understanding of disease and inform therapeutic development, many therapeutics that show promise in preclinical models fail to elicit predicted effects when tested clinically. These meetings explored the relationship between clinical phenotypes of TBI and animal model constructs, and discussed what constitutes a useful translation model system and common data elements for data standardization, particularly in the context of Research and Development decision making.

To develop the Preclinical Traumatic Brain Injury (Preclinical TBI) CDEs, the Preclinical TBI CDE Working Group divided into three sub-working groups to focus on identifying and defining data elements in the domains of:

  • SWG1 - General Health Affective Disturbance (Depression/Anxiety/Social Interaction)
  • SWG2 - Cognition and Motor (Learning/Memory/Sensory/Motor)
  • SWG3 - Large Animal Models (Behavior)

DATA STANDARDS

The Preclinical TBI CDE Working Group, the National Institute of Neurological Disorders and Stroke (NINDS) and the Department of Defense (DOD) CDE Team have released a draft version (Pre-release Version 0.1) of the Preclinical TBI CDE recommendations for Public Review.

Please Note: These recommendations are still in the process of being reviewed, updated, and edited by the Working Group during the public review period. Additional instruments and data will be posted with the final recommendations release in April 2018. We also understand that Preclinical TBI is a relatively new area of data harmonization, specially for large animal models and further clinical investigation is needed.

After the public review period, the Preclinical TBI CDE Working Group will review and revise the recommendations as needed. Version 1.0 of the Preclinical TBI CDE recommendations will be posted by April 2018. Again, please note that changes are still being incorporated and final documents for community use will not be available until April 2018.

PRECLINICAL TBI COMMON DATA ELEMENT PUBLIC REVIEW PACKAGE OVERVIEW

The Pre-release Version 0.1 Preclinical TBI Public Review package consists of one zip file (PreclinicalCDE2_v0.1_113017.zip) containing the following documents:

  1. Instructions
    1. Instructions on reviewing CDE's and submitting comments
  2. CDE Spreadsheet Guide
    1. Description for  the CDE spreadsheet columns; please review columns A, B, C, E, F, G, H, I, J, K, L, M, O, P, Q, R
  3. Quick Start Guide
    1. Provides a reference for each of the tests/outcomes for the preclinical TBI common data elements (CDEs)
  4. Common Data Elements (CDE) sets for each test/instrument
    1. CDE sets are available as excel spreadsheets, which include the CDEs identified and defined by the Preclinical TBI Working Groups. The CDE sets can be used as the building blocks for study data collection forms
  5. Comments form spreadsheet
    1. Reviewers should use this spreadsheet to return comments to the working group (PreclinicalCDE@nih.gov)

It is anticipated that many of the CDEs will overlap across outcome measures and study types, which allows for comparisons and meta-analysis across studies. Consistency of the data elements and the CDE formats is maintained in order to ensure the ability to transfer critical medical information electronically from one center to another. This data harmonization also allows for continuity across different disease areas. The goals of the NINDS/DOD CDE initiative are to increase the efficiency and effectiveness of preclinical research studies and clinical treatment, increase data quality, facilitate data sharing, and help educate investigators who are new to TBI research.

CDE CLASSIFICATION

Each CDE or instrument will be classified according to the definitions below once public review has been completed in April, 2018:

General Core: A data element that is vital to the reporting of all preclinical studies, regardless of disease category.

Disease Core: A data element that collects essential information applicable to any disease-specific study, including all therapeutic areas. The preclinical working groups assign the disease “Core” classification based on a consensus of best research practices from the literature. The disease Core CDEs are a small subset of the available CDEs, and it is anticipated that investigators will need to collect the disease Core CDEs on any type of study since they are vital to the reporting of all disease-specific studies.

Disease Supplemental - Highly Recommended: A data element which is essential based on certain conditions or experimental designs to test the outcome in a particular domain.  In most cases, these are well-established experimental factors that are known to influence the measured outcome. These data elements are highly recommended for the specified disease condition, study type or design.

Disease Supplemental: A data element which is commonly collected in pre-clinical research studies. Use depends upon the study design, protocol or type of research involved. These are recommended, but not vital, for studies.

Disease Exploratory: A data element that requires further validation, but may fill current gaps in the CDEs and/or substitute for an existing CDE once validation is complete. Such data elements show great promise, but require further validation before they are ready for prime-time use. They are reasonable to use with the understanding of their limited validation.

HISTORY AND ACKNOWLEDGEMENTS

Chairs and co-chairs were appointed to lead and the three individual pre-clinical TBI sub-working groups. The Working Group members actively developed the CDEs for their specific subgroups and also had an opportunity to review and comment on the recommendations of the other subgroups. The Preclinical TBI CDE Working Groups were supported by the NINDS/DOD CDE Team.
