A case record form (CRF) is a great and necessary tool used in clinical trials to collect data from each participating patient. CRF (also referred to as case report form) has historically been on paper (unlike electronic ones these days). Traditionally, something like carbon copy paper, where the sponsor can utilize one sheet for the Trial Master File (TMF). In some geographies, smaller studies still use paper CRFs. But, mostly, there is a push and inclination to use electronic CRFs(eCRF) or Electronic Data Capture (EDC) in large/global studies.

What are the advantages of electronic data capture (EDC) or eCRF?

Some are listed below. Do you want to add more?

  1. Easy availability of data – Trial teams, monitors, and auditors can review the data wherever and whenever they want to.
  2. Inbuilt plausibility to ensure the appropriateness of data – To ensure proper data entry, the sponsor can make predefined checks.
  3. Faster accumulation and data transfer – Reduces data entry time, particularly from external devices.
  4. Easy sharing and exchange of information – Users can share data quickly on capture, process, and acceptability with relevant personnel.
  5. Real-Time Automated Edit Checks – Has a clear advantage over paper CRFs.
  6. Facilitate Analysis – Data collected in eCRF are linked with one form to another form for analysis.
  7. Rapid formal reporting – Authorized personnel can access, download, and print status reports any time throughout the study and on completion.
  8. Unlimited security possibility – Any level of security in storage and built an access system.
  9. Higher data quality – increased statistical power.
  10. PRO readiness – Ability to work seamlessly with PRO.

What are common EDC systems available in the market?

There are different kinds of EDC systems developed by various companies, and more are still coming up.

Somewhere in the western world, a clinical trial team of an organization was looking to buy an electronic data capture (EDC) system for their clinical trial projects. There were many choices in the market, and efforts were on to seek feedback on previous experien6ces with these products. One of the team members got an interesting thought to seek this feedback quickly and much more reliably. Why not ask other clinical researchers on a social media group? This generated a pool of responses containing unbiased feedback of user experience with currently marketed EDC systems.

Here are some of the known EDC systems in the market.

  1. Rave from Medidata
  2. Inform from Oracle
  3. Oracle RDC from Oracle
  4. nowEDC from Datatrial
  5. Datalabs EDC from Perceptive(Subsidiary of Parexel)
  6. Macro from Elsevier
  7. QDS EDC from QDS
  8. Data Trak EDC from Data Trak
  9. TrialMaster from Omnicomm
  10. Encapsia from Cmed
  11. IBM EDC from IBM
  12. Target Health EDC from Target Health
  13. Veeva Vault EDC from Veeva
  14. eCaseLink from DSG
  15. Medrio EDC from Medrio
  16. Captivate EDC from clinCapture
  17. REDCap EDC from REDCap Cloud
  18. Nukleus EDC from TCD eClinical
  19. Bioclinica EDC from Bioclinica
  20. Castor EDC from Castor
  21. iMedNet EDC from MedNet

While most of these EDC systems bring advantages suggested earlier, their acceptability in the market differs significantly.

User experience – a key factor in the acceptability of eCRF systems

User experience – the overall experience of a person using a product e.g. EDC or eCRF, especially in terms of how easy or pleasing it is to use, drives a user to like or dislike that product.

It generates perceptions of system aspects such as

  • Utility,
  • Ease of use and
  • Efficiency

for that particular user.

  • It means that the acceptability of a product, including EDC systems, can be a total of various aspects of human-computer interaction and product ownership.
  • For a product like eCRF / EDC, user experience becomes more crucial, with timely submission, review, and stringent data acceptability requirements in clinical research.
  • An EDC system needs to be taken up, understood, and utilized fully by the user. The learning curve should be acceptable and not too steep.

Clinical researchers are aware and the word spreads fast

Considering the complexities of clinical trials, most of the users in the industry undergo fast realization of how user-friendly a system is. With a need to use these systems quite frequently by different kinds of users – clinical study coordinators, investigators, clinical trial monitors, etc. to name a few, any product is likely to generate an impression rather quickly.

What becomes more interesting is how this impression spreads across the industry.

Any prospective buyer (clinical research organization or a trial sponsor) is likely to take feedback from various resources before opting for their best choice. Some of these resources could be

  1. Experience of employees
  2. Feedback from friends, ex-colleagues, and associates of employees
  3. Online reviews of products
  4. Live demonstration of products
  5. Sponsor requirements

This survey makes sure that a good product always gains favorable words and applause quicker than a not-so-good product getting an unfavorable one. Thus, tapping the impressions of users, as they come, is of great importance.

Story of a user-initiated survey on EDC

Somewhere in the western world, a clinical trial team of an organization was looking to buy an electronic data capture (EDC) system for their clinical trial projects. There were many choices in the market and efforts were on to seek feedback on previous experiences with these products.

One of the team members got an interesting thought to seek this feedback quickly and much more reliably.

Why not ask other clinical researchers on a social media group?

LinkedIn, Facebook, and other social media have become virtual community centers for people. They are not only able to stay in touch with their friends, colleagues, and known persons but can connect with various other (unknown) people with similar interests by joining a social media group.

Within clinical research too, there are various groups formed to share information, knowledge, and, very often, a smile.

On a fine evening, one such group received a question from a group member – “What is the best EDC system you’ve ever used?”.

This question generated a flood of responses from many group members. Many people shared what they thought was the best EDC system. A lot of them shared their experiences with such products with more elaborated comments.

The Series of responses received for this survey generated pooled unbiased feedback on various marketed EDC platforms and eCRF systems. Considering the importance of early understanding of user experience, this feedback could be very interesting for clinical researchers, as well as developers of such EDC systems.

Results of the survey

They analyzed the survey responses. They considered all the product comments. Responses/comments/feedback on these products were also listed and classified into three categories.

  • Select’: They considered the positive feedback from the products.
  • ‘Reject’: A list of negative responses was listed.
  • ‘Detest’: In this category, they considered the strong dislike than just rejection from the users.

This survey received a total of 207 responses at the time of preparation of this article. Here is the result of the analysis performed using the above-referred categories.

  • The majority of respondents prefer Rave from Medidata and Inform. Roughly half of the responses indicated a favorable view of Medidata, while more than 30% of feedbacks favored Inform.
  • There were some negative responses as well. But, it’s interesting to note that Rave and Inform had negligible negative feedback.
  • Oracle RDC was the only product with more negative responses than positive ones.

Results of another survey on EDC systems other than Rave

A different user performed a survey to find recommendations on products other than a rave. Since Rave stood out as an undisputed winner among the respondents in the earlier survey, the findings of the second survey become crucial to assess the second choice for an eCRF system.

Among 93 responses, there were 44 positive responses for Inform, which is nearly 50%. Inform again stood out as the clear choice of the EDC platform.

However, it is also interesting to note that the second choice of users after Inform, is Oracle RDC here.
