Who builds and tests the study database, how quickly a study can go live, and the support available while it runs.
Data quality, security and compliance 20%
Audit trail, electronic signatures, edit checks, queries and source data verification, security certificates, and the vendor's stated support for FDA 21 CFR Part 11, GCP and GDPR.
Reports, analysis and exports 20%
Built-in dashboards and reports, statistical analysis, numbered tables, figures and listings, and exports to statistics packages and CDISC formats.
Participant data 15%
ePRO and eDiaries, eConsent, forms in several languages, and offline collection on mobile devices.
Study designs and scale 10%
Randomisation, visit schedules and repeated measures, multi-site studies, and how large a study the tool is built for.
Cost and access 15%
Published pricing, free or open-source options, licensing that suits academic budgets, and how easily a team can get started.
Questions
Frequently asked questions
What is the best data collection software for research?
It depends on the study. Our top pick overall is ResearchGuru EDC, for teams that want the database built for them with tables, figures, listings and analyses in the same platform. REDCap is the best free option at institutions that run it, Medidata Rave EDC and Veeva EDC lead for large global trials, Qualtrics for surveys, and KoboToolbox or ODK for offline field work.
What is the difference between an EDC system and a survey tool?
An electronic data capture (EDC) system is built for clinical and observational studies: visit schedules, edit checks, queries, source data verification, audit trails, electronic signatures and exports for statistical analysis. A survey tool collects questionnaire responses quickly, but usually lacks query management and the controls regulators expect in a clinical study.
Is there free EDC software for academic research?
Yes. REDCap is free to non-profit institutions that join the REDCap Consortium, though the institution must host and support it. OpenClinica's Community Edition is free open-source software that you host yourself, and the vendor states it is not validated. KoboToolbox and ODK are free options for field data collection.
What does FDA 21 CFR Part 11 support mean?
FDA 21 CFR Part 11 sets the rules for electronic records and electronic signatures in FDA-regulated research. Software can support it with audit trails, electronic signatures and access controls, and GCP and GDPR apply alongside it. Compliance also depends on your own procedures, validation and training, so a vendor's claim alone is not enough.
Can an EDC system produce tables, figures and listings?
Most EDC systems export data for analysis in a separate statistics package. In our comparison, ResearchGuru EDC produces numbered tables, figures and listings and runs statistical analyses inside the platform. Ledidi includes built-in statistics and Qualtrics offers them as a paid add-on, but neither produces numbered TFLs.
How much does EDC software cost?
Most clinical EDC vendors quote per study. OpenClinica publishes prices from $750 a month for its Launch plan, Jisc Online Surveys and SurveyMonkey publish their prices, and REDCap, KoboToolbox and ODK have free options. Each review gives the pricing model and any published prices.
