eSource Solutions

The TransCelerate eSource Initiative, begun in 2016, aimed to assist sponsors in overcoming challenges in moving towards more efficient data gathering practices to benefit patients, sites, and sponsors.  The key outcomes of this work are below.

While the eSource Initiative is completed, TransCelerate remains invested in the pursuit of global implementation of eSource through our engagement with the Vulcan FHIR® Accelerator, launched in 2020. We envision that our involvement in the work produced by Vulcan will pave the way for increased usage of eSource approaches in clinical trials.

What is eSource?

The Food and Drug Administration (FDA) defines eSource, or electronic source data, as data initially recorded in an electronic format. The TransCelerate eSource workstream further categorizes eSource into the four groups shown below:

*The eSource team recognizes that some technologies may apply to more than one modality and that these modalities will likely evolve over time due to technological advances.

What is the Anticipated Value of eSource?

  • Eliminate unnecessary duplication of data
  • Reduce the possibility for transcription errors and eliminate transcription of source data prior to entry into an electronic case report form (eCRF)
  • Facilitate remote monitoring of data; promote real-time access for data review
  • Facilitate the collection of accurate and complete data

Major challenges with eSource Adoption

There are several key challenges with eSource adoption.

  • Lack of change management
    • Acceptance of novel technology solutions that enable eSource and unknown quality and regulatory clarity on the data in these solutions.
  • Lack of system interoperability
    • Interoperability is referred to by the Institute of Electrical and Electronics Engineers (IEEE) in basic terms as “the ability of a system or a product to work with other systems or products without special effort on part of the customer. Interoperability is made possible by the implementation of standards.”
  • Concerns over eSource acceptability as endpoints; lack of clarity from key study stakeholders
  • Low risk tolerance in pharma industry

The industry must reach common understandings about novel endpoints, data standards, system validation, and related issues. While technology in itself is not a significant barrier to eSource implementation, interoperability among systems is an enormous challenge to establishing a complete end-to-end electronic health care and research ecosystem.

Here are some key metrics from several industry projects that quantify the value of eSource:

2021 eSource Informatics Reference Guide for Clinical Research Sites

The eSource Informatics Reference Guide for Clinical Research Sites provides information on clinical research informatics, the basics of informatics, and possible resources to expand capabilities around interoperability and data exchange for clinical sites. In mid-2018 and into 2019, the TransCelerate eSource team engaged with a Site Advocacy Group (SAG) in collaboration with the Society for Clinical Research Sites (SCRS) for an information gathering exercise via voluntary site survey to discuss challenges and areas for improvement in conjunction with technology use in clinical trials.

Results from the survey and the following discussions showed the inconsistencies between the wider adoption of eSource in the industry and the level of understanding at sites. ​The eSource Informatics Reference Guide for Clinical Research Sites was developed to provide guidance to sites on their journey to eSource and interoperability readiness.

2021 eSource Informatics Continuum

The objective of the eSource Informatics Continuum is to help study sites determine their readiness for eSource implementation, by identifying their location on the continuum and pathway to increase interoperability. Interoperability is key to the exchange of source data electronically for research. The continuum includes a diagram that shows different varying degrees of interoperability based on clinical informatics, starting with ‘traditional’ data collection, i.e. using paper medical records and paper case report forms (CRFs), and ending with ‘innovative’ data collection, which includes full interoperability and integration between clinical care and clinical research.

2021 Site Capability Questionnaire

In Guidance for Industry Electronic Source Data in Clinical Investigations, eSource is defined as “data initially recorded in an electronic format is considered eSource. This can include information in original records and certified copies of original records of clinical findings, observations, or other activities captured prior to or during a clinical investigation used for reconstructing and evaluating the investigation.” The Site Capability Questionnaire is intended to help capture the site’s use of technology during the site qualification process that is conducted prior to the start of a study. The intent of this form is to facilitate the reduction of any administrative burden on Investigative Sites by collecting information in a consistent way across multiple sponsor companies–reducing the duplicative completion of similar forms across multiple studies.

2020 Accelerating the Adoption of eSource in Clinical Research: A TransCelerate Point of View

What needs to change to increase eSource adoption? The paper, Accelerating the Adoption of eSource in Clinical Research, a TransCelerate Point of View, describes the desired future state of clinical research where all source data are completely electronic, with an adequate quality that is fully acceptable in clinical trial submissions, from the point of view of TransCelerate member companies. To get to that future state, the paper describes five key challenge areas that need to be addressed before the future state can be obtained.

  1. Clinical Trial Design, Protocol, and Data Collection
  2. Automated Data Exchange, Security and Privacy
  3. New Roles

2017 Best Practices for Non-CRF Data

In Optimizing the Use of Electronic Data Sources in Clinical Trials, The Landscape, Part II, non-Case Report Form (CRF) data are defined as data which include collection and transfer of data in electronic format from internal clinical trial sponsor sources (e.g., specialty laboratories) or external vendors (e.g., laboratory results, imaging, ECG, randomization, drug accountability) into clinical research data repositories/warehouses without entering the data on a CRF. Although sponsors must collect and retain this data, there is currently no applicable industry guidance. Well-thought-out practices and procedures for the collection and retention of non-CRF data are crucial to maintaining data accuracy and integrity. To guide the development of such practices and procedures, this paper outlines certain high-level best practices related to handling and managing non-CRF data. These are high-level suggestions, as the purpose is to share learnings to enable more efficient, effective use, and/or adoption of eSource. The suggestions can and should be tailored to each company’s individual circumstances. These considerations can also help companies to address or reduce challenges that they have encountered and/or to initiate discussions to help improve processes.

2016 Optimizing the Use of Electronic Data Sources in Clinical Trials: The Landscape, Part 1

In 2016, a survey was conducted among TransCelerate member companies to understand the sponsor landscape around eSource at that moment in time, as the initiative’s intent is to facilitate the industry’s movement toward optimal usage of electronic data sources. This paper describes the results of that survey. The survey indicates that member companies had begun taking steps to leverage current eSource technologies and prepare for optimal utilization of electronic data sources already at that time. The most important factors related to the successful implementation of devices/apps based on experience in conducted studies are shown below.

Data Standards

Addressing interoperability constraints is a necessary enabler of achieving the desired future state – global implementation of eSource. The eSource workstream considered new techniques, applied standards, and leveraged innovative technology platforms to remove these constraints. In partnership with Health Level Seven (HL7), the team worked toward bridging the gap between CDISC and HL7 standards, harmonizing the existing standards, and advancing the maturity of HL7® FHIR® for use in clinical research.

Lab Data Use Case: The use of local labs, where each lab may have distinct processes and data collection systems, introduces the need for a standardized structure for the exchange of laboratory data. Without standard guidance to utilize in data transfer, data are inconsistently exchanged, in a variety of formats, increasing the burden on both the site and the research sponsor. This may increase cost, complexity, and timelines for clinical trials. FHIR® provides an effective standard for sites and sponsors to utilize in exchanging clinical research laboratory data. 

For illustration purposes only

To address this need, we developed a mapping to assist sponsors in understanding how the HL7 FHIR® format (an interchange standard emerging in many EHR systems) relates to their existing CDISC standards for transmitting laboratory from sites to sponsors. This solution could have the potential to decrease costs and timelines in the exchange of information between sites and sponsors. The eSource Initiative partnered with HL7’s Biomedical Research and Regulation (BR&R) Working Group to deliver a FHIR® Implementation Guide (IG) that contains the mapping process deliverables and provides requirements to Sites who seek to share data via FHIR®. The deliverables have been published on the HL7 website: http://hl7.org/fhir/uv/cdisc-lab/STU1/

Other Available Standards for Research Use

At the time of writing, the Vulcan FHIR® Accelerator has published two IG’s defining standards that further the objective to connect clinical research with clinical care.
