Tips for Seamless eCRF Design in Clinical Trials

By Editorial Team on April 5, 2024

Designing electronic case report forms (eCRFs) in clinical research is a balancing act between practicality and accuracy. While there’s no universal blueprint, sticking to key eCRF principles can transform your study build from ordinary to outstanding. Let’s discuss the essentials of eCRF design with these top tips:  

  1. Match Site Workflow: When designing eCRFs, consider the protocol and the needs of your sites and ensure that forms align with their workflow. This may involve creating separate forms for different activities or roles to streamline data entry and enhance efficiency. 
  2. Reflecting Paper Forms: Familiarity breeds acceptance. When eCRFs mirror the paper forms outlined in the protocol, clinicians feel right at home. This is especially crucial for sites transitioning to a new Electronic Data Capture (EDC) system. 
  3. Find the Right Length: Finding the sweet spot in form length is crucial. Splitting up fields across multiple forms can result in an excessive number of forms per study visit, while too many fields on a single form can overwhelm users and lead to data entry errors. Aim for a balanced approach that ensures forms are comprehensive yet manageable. 
  4. Organizing with Purpose: Organization is key. Grouping related fields reduces entry errors and enhances the visual appeal of the form. 
  5. Consider Masking Implications: Implement masking to safeguard sensitive data and maintain trial integrity. Leveraging masking features in eCRFs allows you to conceal certain data elements from unauthorized users.  
  6. Use “Skip Logic” Where Appropriate: Guide users through forms intuitively by controlling field visibility based on contextual relevance. 
  7. Copy Data Between Forms: Streamline data entry by automatically propagating shared information across multiple forms. By enabling the copying of data between forms, you can minimize redundant data entry efforts and reduce the likelihood of transcription errors. 
  8. Limit Free Text Responses: Opt for structured input methods to enhance data quality and analysis. Free text responses can introduce variability and make data interpretation more challenging. Structured input methods, such as dropdown menus or radio buttons, help standardize data entry and facilitate data analysis. 
  9. Avoid Excessive Edit Checks: To prevent unnecessary hurdles, balance data validation and user flexibility. While edit checks are essential for ensuring data integrity, an excessive number of checks can hinder the data entry process and frustrate users. Focus on implementing meaningful edit checks that target critical data points without impeding user workflow. 
  10. Seek User Feedback: Validate form intuitiveness by observing real users in action and refining based on their feedback. By incorporating user feedback into the design process, you can create eCRFs that are truly user-friendly and effective. 

In conclusion, designing user-friendly eCRFs requires careful consideration of various factors, including familiarity, form length, workflow alignment, data integrity, and information organization. By following these essential tips, you can create eCRFs that not only meet the needs of your study but also enhance the overall efficiency and effectiveness of data collection processes.
