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.

New eCF ISF System Assessment!

Published on 08 April 2024

New eCF ISF System Assessment!

eClinical Forum now has 2 FREE assessment forms for sites to self-assess their systems for use in regulated clinical trials. We are excited to release the first version of the “ISF System Assessment”.   This assessment form is very similar to our eSource-Readiness Assessment (eSRA) and is, like eSRA, based on regulatory documents from regulators around the globe.

It is a response to the growing expectation by regulatory agencies for clinical trial sponsors to verify that clinical research site systems comply with requirements to protect confidentiality and provide accurate and reliable data for the use in a regulated research environment.  In particular, the EMA Guideline on computerised systems and electronic data in clinical trials (effective Sep 2024) states s in A6.2: “the sponsor should assess the systems in use by the investigator/institution to determine whether the systems are fit for their intended use in the clinical trial (e.g. include an audit trail). The assessment should cover all computerised systems used in the clinical trial and should include consideration of the rights, safety, dignity and wellbeing of trial participants and the quality and integrity of the trial data. If the systems do not fulfil the requirements, the sponsor should consider whether to select the investigator/institution. The use of systems not fulfilling requirements should be justified, either based on planned implementation of effective mitigating actions or a documented impact assessment of residual risks.”

The eClinical Forum offers 2 system assessment forms for investigator sites, sponsors, CROs, and regulators to use free of charge, to evaluate the suitability of an investigator site system to provide data/records for clinical trials. They are:

  • e-Source-Readiness Assessment (eSRA)
  • e-Investigator Site File System Assessment (ISF Assessment)

The 2 system assessment forms contain questions based on regulations and guidelines from global regulatory agencies for clinical research.  Since 2016, eSRA has been globally in use and regulators have accepted its inclusion in study materials. In 2024, the The ISF Assessment, based on eSRA, was released on the request of our eSRA users.  The eCF intends to publish an update to these materials annually, in Q1, to keep current with regulations and guidelines.

  • Each assessment form is packaged in a handbook providing guidance to sites on how to complete the form. The form should not be separated from the handbook, except after completion. 
  • The document “Implementing eSRA – Sponsor Assessment”, while written for eSRA, applies equally to implementing the ISF Assessment.
  • A joint document, “Regulatory documents used as a basis for the eClinical Forum eSRA and ISF Assessments” shows the correlation between these 2 assessment tools and the underlying regulatory documents.

The eClinical Forum, a non-commercial, non-profit global organization with over 45 organizations active in clinical research, has established criteria to allow compliant use of data from healthcare systems for regulated clinical research. Both assessment forms have been created with sponsors and research sites to simplify the self-assessment of research site systems. It is a standardized approach and free of charge, and allows sites to reuse their assessment across all their clinical trial sponsors.  These assessment forms will be updated annually, based on new information that has been provided by regulators during the year.

Both assessments and all associated resources can be accessed (for free) from the tab on this website labeled "Site Sys Assmts" ... or by using these links:  … or by using this link: Site Sys Assmts (

The original tab, used to access eSRA (eSource-Readiness Assessment) since 2016, will remain available until 1-July-2024 and then it will be removed and eSRA will only be available through the joint webpage with the ISF Assessment. Please update any internal materials you have that point to the eSRA webpage, to now point to

As always, we appreciate your feedback and questions regarding our assessment forms. Please send comments and questions to .
