EOL Conception — Create Your eCRFs Independently

EOL Conception is the integrated design module of the EOL© suite that lets you design, configure, and test your clinical studies completely on your own. It’s aimed at sponsors, project managers, data managers, or designers who want end-to-end control over their eCRF configuration.

A powerful, intuitive, and structured tool

EOL Conception is built on a clear architecture (questionnaires > pages > blocks > variables) for a smooth, rapid learning curve. With an ergonomic interface and intelligent entity management, you structure your forms to match your protocol’s real needs, following best design practices.

Create, test, validate

The module includes :

  • A complete graphical design environment for eCRFs,
  • A version-control system,
  • A rule engine for consistency checks, events, alerts, and more,
  • A real-world testing platform via the eCRF mock-up.

You can test every element (page, block, variable) in “magnifier” mode without waiting for compilation.

Quality control and compliance built in

Define powerful, targeted checks for data inconsistencies, protocol deviations, adverse-event monitoring, etc. Everything complies with current regulatory requirements (GCP, GDPR, FDA 21 CFR Part 11) and logs every change in an audit trail.

Maximum flexibility

Use EOL Conception however you need :

  • Fully autonomously under license,
  • In collaboration with our data-management teams,
  • >Or co-designing with your CROs or subcontractors.

An administrator account lets you manage studies, user profiles, a reusable block library, and export deliverables (annotated eCRF, Data Handling Manual, control-list, etc.).

Advanced Design Features

Create dynamic, intelligent eCRFs tailored to any clinical scenario.
EOL Conception offers complete flexibility in field creation, data-entry logic, controls, and interactivity.

Available Field Types

You can use a wide range of fields to faithfully model your protocol :

  • Text fields (single-line, multi-line, structured)),
  • Date fields (full or partial),
  • Custom dropdown lists (sortable, with sub-lists),
  • Radio buttons, checkboxes ((independent or exclusive),
  • Numeric fields (integers, decimals, with min/max bounds),
  • Specialized fields (email, phone, age, name, etc,
  • File-upload fields (document import via eCRF)
  • Visual analog scales (EVA/slider),
  • Hidden or pre-filled fields with default values.

Dynamic Logic & Smart Forms

With visual or assisted scripting, you can set up :

  • Conditional field hiding (display based on another answer),
  • Cascading blocks via multi-level triggers,
  • Read-only fields (for calculations or locked data),
  • Fields dependent on stratum, treatment arm, or randomization stage,
  • Automatic pre-fill from enrollment data (name, age, sex, date, etc.).

Calculation Formulas

Embed your own formulas to generate values dynamically :

  • Simple computations: scores, indices, totals (BMI, body surface area, etc.),
  • Conditional calculations (if/then/else),
  • Hidden or visible computed fields as needed,
  • Use computed results as criteria in checks or triggers.

Consistency Checks & Business Rules

Build powerful, code-free checks to ensure data quality :

  • Detect entry errors, outliers, protocol non-compliance,
  • Trigger alerts on adverse events, management errors, inclusion-criteria breaches,
  • Trigger alerts on adverse events, management errors, inclusion-criteria breaches,
  • Maintain a complete audit trail for every entry, edit, or validation.

All features can be tested in real time via magnifier mode or mock-up generation, no pre-production required.
