Overview
The Manage CRFs (Forms) section is your central hub for managing all Case Report Forms (CRFs) in your clinical study. CRFs are the data entry forms completed for each subject at each event/visit.
The system provides two integrated views to help you manage CRFs efficiently:
- CRFs in Study: Manage CRFs currently active and assigned to your study
- Available CRFs: Library containing all CRFs in the system for reuse or creation
Who should use this guide:
- Study Administrators setting up forms for the study
- Clinical Data Managers structuring and standardizing data collection
- Form Builders designing form interfaces and logic
What you'll learn:
- How to view and manage CRF versions in your study
- How to reuse CRFs from other studies
- How to create new CRFs from Form Builder
- Best practices for naming and managing CRF lifecycle
📋 CRFs in Study
This view displays all CRFs currently active and assigned to your study. This is where you control form status and edit content.
| Area | What it is for | When to use |
|---|---|---|
| CRFs Table | View list, status, and versions of CRFs | When you need to review forms in your study |
| Row Actions | Preview or Edit CRF | When you need to review interface or fix logic issues |
| Versioning | Manage CRF update versions | When protocol changes or data fields need to be added |
CRFs Table
This table provides an overview of all CRFs in your study:
| Column | Required | Description | Example |
|---|---|---|---|
| Name | ✓ | Display name of the CRF | Demographics, Vital Signs |
| Latest Version | ✓ | Currently active version identifier | V.1.0, VI_1.0.1 |
| Status | ✓ | Current status | Available (Ready), Draft, Locked |
| Created On | ✓ | Date and time CRF was created | 19/01/2026 10:36 |
| Created By | ✓ | User who created the CRF | James David 1 (root) |
| Last Updated On | ✓ | Date and time of last update | 12/03/2026 15:14 |
| Description | Description of CRF purpose | Collects demographic information and medical history |
Row Actions
| Action | Description | When to use |
|---|---|---|
| Preview | Opens CRF interface in read-only mode | Review interface, question order, and display logic before assigning to event |
| Edit | Opens CRF in Form Builder for editing | Add/remove data fields, modify calculation rules, update labels |
CRF Versioning
The system supports version control for CRFs:
- When you edit and publish an Available CRF, the system automatically creates a new version
- The Latest Version column displays the most recent version
- ⚠️ Important Note: Previous versions are retained for reference. If subjects were enrolled under an older version, their data will not be affected by the new version
Assigning CRFs to Events
CRFs only become functional when assigned to an Event (e.g., Screening, Baseline, Week 4)
- ⚠️ Mandatory Requirement: CRF must have Available status before it can be assigned to an Event
- How to do it: Navigate to the Manage Events page to assign CRFs to corresponding visits
💡 Pro Tip: Name CRFs to reflect their clinical purpose (e.g., "Vital Signs", "Adverse Events", "ECG Assessment") rather than generic names like "Form 1", "Form 2". This makes the Subject Matrix much easier to navigate.
🗂️ Available CRFs Library
This view displays the entire CRF library in the system database. This is your resource library to save time by reusing standardized forms.
| Area | What it is for | Impact |
|---|---|---|
| Available CRFs Table | View all CRFs in the system | Helps find and reuse CRFs from other studies |
| Add Existing CRF | Add existing CRF to current study | Saves time redesigning from scratch |
| Create New CRF | Navigate to Form Builder to create new CRF | Design custom forms specific to your study |
Available CRFs Table
This table includes an additional Study column compared to the "CRFs in Study" table:
| Column | Description |
|---|---|
| Study | Name of the original study that created or uses this CRF |
| Actions | Add or Assign button to include CRF in current study |
Adding an Existing CRF
Instead of creating from scratch, you can "borrow" CRFs from other studies (e.g., reuse the "Demographics" form from a previous study):
- Navigate to Available CRFs tab
- From the left menu, select Available CRFs
- Search for desired CRF
- Use the search bar or scroll through the list
- Check the Status column to ensure CRF is Available
- Add to Study
- Click the Add (or Assign) button in the Actions column
- Confirm the action. The CRF will immediately appear in the CRFs in Study tab
- Assign to Event
- Return to the Manage Events page to assign the newly added CRF to appropriate visits
Creating a New CRF
If no suitable CRF exists in the library, you can create one from scratch:
- Navigate to Form Builder
- Click the Go to Form Builder button/link
- Create New CRF
- Select Create New CRF
- Name and describe the CRF
- Design Interface (Drag-and-Drop)
- Drag components from the toolbar into the form:
- 📝 Text inputs: Text, numbers
- 📅 Date/time pickers: Date and time selection
- 📋 Dropdowns / Radio / Checkbox: Response options
- 🧮 Calculated fields: Auto-calculated fields (BMI, Age, etc.)
- ✍️ Signature fields: Electronic signatures
- 📎 File upload: Images, documents
- Drag components from the toolbar into the form:
- Configure Logic & Validation
- Set required field rules, display conditions (Skip logic), and error warnings (Range checks)
- Save and Publish
- Click Save and change status to Available
- Return to Manage CRFs
- The new CRF will appear in the Available CRFs list and is ready to be assigned to your study
✅ Best Practices
To ensure data collected is accurate, consistent, and easy to maintain, follow these principles:
1. Naming Convention
| Do's | Don'ts |
|---|---|
✅ Use descriptive names reflecting purpose: Vital Signs, Medical History | ❌ Use generic names: Form 1, Test CRF, Untitled |
✅ Add prefix if needed: AE - Adverse Events, LAB - Lab Results | ❌ Use special characters in ID: CRF#1, Form@2 |
| ✅ Use clear, concise names that are easy to understand | ❌ Use overly long names that get truncated in displays |
2. Versioning
- Always document the reason for updates in the CRF Description when creating a new version (e.g., "V1.2 - Added 'Discharge Date' field per Monitor request")
- Avoid deleting fields that already contain data. Hide them instead of deleting them
- Keep a version history log for audit trail purposes
3. Reusability
- Design CRFs in a modular fashion. For example: Separate "Demographics" form from "Medical History" form so they can be reused across multiple studies
- Create standardized CRF templates for common data collection needs (vital signs, adverse events, concomitant medications)
4. Testing Before Assignment
- Always use the Preview button to test the interface on both Desktop and Mobile before assigning CRF to Event
- Enter dummy data to verify calculation rules and validation work correctly
- Test skip logic and conditional display rules thoroughly
5. Documentation
- Maintain a CRF Completion Guidelines document that explains each field's purpose and acceptable values
- Include field-level instructions in the CRF design where appropriate
- Document any custom validation rules or calculations
🐛 Troubleshooting
Issue 1: CRF Not Displaying When Assigning to Event
Symptoms:
- When navigating to Manage Events, the CRF list is empty or the newly created CRF is not found
Causes:
- CRF has not been changed to Available status (still in Draft)
- CRF has not been published after editing
Solutions:
- Return to CRFs in Study or Available CRFs tab
- Navigate back to the CRF management page
- Check Status column
- Verify the CRF shows Available status
- If status is Draft:
- Open CRF in Form Builder
- Click Publish or Set as Available
- Save changes
- Return to Manage Events and try assigning again
- The CRF should now appear in the selection list
Issue 2: Cannot Edit CRF (Edit Button Disabled)
Symptoms:
- Edit button is grayed out (disabled) or shows error when clicked
Causes:
- CRF is in Locked status
- CRF has been assigned to Event and subjects have already entered data (data integrity protection)
Solutions:
If CRF is Locked:
- Contact Study Administrator to unlock the CRF
- Provide reason for unlock request
- Administrator will change status from Locked to Available
If CRF has existing data:
- System will automatically create a new version when you edit
- Old subject data will be mapped to the new version
- ⚠️ Warning: Deleted fields will lose their data
- Consider using Hide field instead of Delete field
- Test the new version thoroughly before publishing
Issue 3: Data Lost After CRF Version Update
Symptoms:
- After updating CRF to V2.0, some old subject data fields no longer display
Causes:
- You deleted (Delete) data fields in V2.0 instead of just hiding them (Hide)
Solutions:
Prevention:
- ⚠️ Never delete fields that contain data
- Use Hide field or Disable field features instead
- Document all field changes in version notes
Recovery:
- Restore the previous version (V1.0) if possible
- Contact Technical Support to remap data from database
- For future updates, always test version changes in development environment first
