The tool contains questions based on regulations and regulatory agency guidelines for clinical research data sources and should be used to evaluate the suitability of an Investigator Site computerized system to provide data for clinical trials. An eClinical Forum team, comprised of CRAs and Data Managers from different clinical research sponsor organizations and CROs and representatives from sites, has produced the "eSource-Readiness Assessment", otherwise known as "eSRA" for sites to perform a self-assessment of their computerized system's ability to be compliant with clinical research regulations.

Clinical research draws on a combination of data collected during a clinical trial and historical medical information relating to the research subject(s). Many of the data points needed for clinical research are originating in Electronic Health Record Systems, making them "eSource" for clinical research. Even if these data points are not used directly from the site's healthcare system, but are re-entered into a Sponsor's system for a clinical trial, the source of the information (the healthcare system) must still be confirmed as compliant with standards set forth in clinical research regulations and applicable guidance documents.

The eSRA Questionnaire Version 2024 can be downloaded as part of the eSRA Handbook below.  (This version incorporates changes based on the EMA Guideline on computerised systems and electronic data in clinical trials.)

Notice to those intending to include eSRA in their own materials: Copyrighted by the eClinical Forum 2024. The eClinical Forum keeps all rights of this material. Please see the License for Fair Use in the eSRA Handbook and “Implementing eSRA” Guide. We welcome eSRA to be used in other formats, however, it is required that eSRA text be used exactly, that all eSRA questions are included, that your use of eSRA is updated when eCF eSRA is updated, and that eClinical Forum is notified in writing and credited. By using these materials, you acknowledge the terms and conditions for use.  The eClinical Forum is only responsible for the eSRA materials as distributed via the eClinical Forum website. If using the eCF form, downloaded from this website, in it's original format, there is no need to notify eCF.

Stay Current!!

As new regulations are released or updated, the eClinical Forum will evaluate if the eSRA questions should be updated. To be notified of future releases of the eSRA Questionnaire, please send an email to Your email address will not be used for purposes other than to inform you of updates to eSRA.

Sponsors & CROS -- Please take our very brief survey regarding how you are using eSRA.  This will help us improve eSRA. Survey link: eCF eSRA Survey ( THANK YOU!!!

Do we keep a list of sites that have completed eSRAs?

We have frequently been asked if we can provide a list of which sites have already completed an eSRA. Due to privacy laws in different countries, eClinical Forum does not keep such a list. We supply the eSRA questionnaire, free of charge, to anyone who wants to use it. We encourage sponsors to keep a list for themselves of which sites they have received a completed eSRA from. We encourage sites to store their completed eSRA in a central location (such as their IT department) so that other groups within the same organization / using the same electronic healthcare system, can use the completed eSRA as a basis to complete their own eSRA.

Assessing Investigator Site File Systems for Clinical Research

Assessing Investigator Site File Systems for Clinical Research

This article was compiled using information from the eCF eSRA and eISF Teams by: Pablo Perez, Lead Quality Assurance Data Integrity, Astellas

More and more, clinical research sites are implementing electronic systems for managing essential records generated from conducting a clinical trial. Sites are either internally developing a system or purchasing an off-the-self solution. In either case, the records that the system will manage must meet data integrity principles, global regulations and regulatory guidelines for Good Clinical Practice (GCP) from FDA, EMA, MHRA PMDA and ICH to be acceptable for use for the clinical trial. The recent EMA “Guideline on Computerized Systems and Electronic Data In Clinical Trials”[3] section 4.6 Criticality and Risks, states “For systems deployed by the investigator/institution, the sponsor should determine during site selection whether such systems (e.g. electronic medical records and other record keeping systems for source data collection and the investigator site file) are fit for purpose.”

The eClinical Forum[1], a transatlantic, not-for-profit and non-commercial, technology independent group representing members of the pharmaceutical, biotechnology, and allied industries have created an assessment tool that is available for free to both Sponsors and Sites. The assessment tool is to determine GCP compliance of a site’s Electronic Investigator Site File (eISF) System for managing essential records used in a regulated clinical trials. Completing the tool is not a regulatory requirement; however, it may be used to demonstrate that regulatory requirements have been satisfied. Sponsors and sites can use the assessment to discuss any potential risks and appropriate mitigations. NOTE: Sponsor-supplied systems do not need to be assessed by the clinical research site. This assessment is only intended for investigator site supplied systems.

The eClinical Forum ISF assessment tool contains a set of questions based on regulations and regulatory agency guidelines for electronic systems used in clinical research as identified in the eClinical Forum “Requirements for Electronic Data for Regulated Clinical Trials[2] ”.  

The ISF assessment tool is available for free download (no information is collected in return), along with its “sister” assessment tool for assessing clinical reasearch source systems (e.g. patient medical records systems) from their website at

The eISF assessment tool is of great benefit to all players in the clinical research realm. In particular, the following should be noted:

Clinical Investigators

  • Clinical Investigators are encouraged to use this tool to assess their systems, for which they are responsible, that manage essential records that will be used in a clinical trial.
  • A site should be aware that a “No” answer to a question does NOT mean that the site will be rejected, but rather that the Sponsor will work with the site to ensure that any potential risk is mitigated.
  • It is the site’s responsibility with respect to system installation, validation and maintenance. This may be handled by their organization’s IT department and/or a vendor. In these cases, the site is still responsible for ensuring that these other parties are fulfilling these responsibilities for any system providing data/documents in the clinical trial through a contract/agreement.
  • Sites should retain a record of this assessment for use in improving their system and processes and to assist them with future system assessments.
  • A site can avoid multiple requests from different Sponsors for information pertaining to regulatory appropriateness of their system, as the same completed eISF assessment can be given to each Sponsor they work with for review.

Sponsors / CROs

  • Sponsors are encouraged to ask sites to use this assessment tool to determine if a site’s eISF is GCP compliant.
  • Sponsors should obtain a completed assessment from their site and this assessment should be retained in their Trial Master File.
  • Sponsors may have additional questions for determining if a site is suitable for their clinical trial; however, the questions in this assessment are the minimum requirements based on US, EU and Japan regulations, guidance documents, directives and reflection papers. A list of all regulatory documents used as a basis for the assessment can be found at
  • The assessment tool does not “certify” or “qualify” the site’s system but merely provides information to the Sponsor for evaluation of the appropriateness of site’s eISF. 
  • It is up to each individual Sponsor to review a completed a completed eISF assessment and does not provide certification or an “answer” as to whether the site as a whole is appropriate – it only indicates the site responses to each question. If a site is not compliant with all the questions, we recommend that the Sponsor work with the site to find suitable mitigations for the potential risks. 
  • If after reviewing a completed eISF assessment from a site, the Sponsor believes there are too many risks to warrant using the system, then the system (and perhaps the site) should not be used for clinical research. However, the site may be given a period of time to make necessary adjustments to comply with questions in the assessment and may ultimately comply such that the system can be used for clinical research.


  • Regulators benefit by a common assessment that is mapped to US, EU and Japan regulations, guidance documents, directives and reflection papers. 

The eClinical Forum commits to updating the eISF assessment questions as needed when updates are made to the underlying regulatory documents and/or new pertinent documents are released from any of the regulatory authorities listed above. The eISF Handbook and Assessment template can be downloaded for free at

All are encouraged to provide feedback to the eClinical Forum regarding interpretations of regulations, eISF assessment questions, etc. via
