Question 1

What is Electronic Data Capture (EDC) Software?

Accepted Answer

Electronic data capture (EDC) software collects and manages patient data for life sciences organizations during clinical trials, replacing traditional paper collection systems. This software improves data quality, streamlines data collection, and ensures regulatory compliance. Electronic data capture evolved from remote data entry (RDE) systems used in the 1980s, which allowed for local data collection on portable computers. EDC systems, by contrast, allow web forms to be created and accessed on the Internet, eliminating data silos and serving as a central hub for source data. 
 Depending on the EDC software, patient data may either be transcribed from paper forms or collected electronically at its source (e-source). This data is then saved as an electronic case report form (eCRF). Clinical trial participants may use connected devices to input responses, but study coordinators at research sites will commonly collect and manage data in the EDC system. Sponsors and contract research organizations (CROs) may also interact with the software for data verification, validation, or management. 
 EDC systems are most beneficial for assessing pharmaceutical and medical device safety, often in later phases of trials, but can be employed in various clinical trials. They significantly reduce the time needed for clinical study design and trial data collection while reducing human error and improving data workflows.

Question 2

What are the Common Features of Electronic Data Capture (EDC) Software?

Accepted Answer

The following are some core features within EDC software that can help clinical trials manage data collection: 
 eCRF builder: eCRFs are intended to mimic paper forms, and EDC software provides point-and-click or drag-and-drop tools to build out case report forms and store templates for future use. Versioning allows eCRFs to be iteratively tested, with audit logs to track changes to forms over time. Collaboration tools allow multiple study and site staff to work from the same interface, building out forms exactly as they’ll appear to trial participants. eCRFs can be built to ensure erroneous data isn’t collected and specific triggers occur based on responses. Some EDC systems may also offer a library of standard form templates gathered from external sources. 
 Data entry and collection: Once eCRFs have been approved for use in clinical trials, data can be collected from trial participants and assigned to the right forms within the EDC system. Study coordinators can edit check data in real-time based on pre-designated protocols whenever discrepancies arise. Depending on the system, participant data can be collected from any device, with some allowing for randomization to protect clinical trial integrity. Modern EDC software also supports cloud data storage and API integration to support batch data importing and exporting. 
 Data validation: EDC software allows collected data to be checked against defined clinical trial protocols, ensuring both completeness and correctness of all captured clinical data. This ensures that trials are being conducted in compliance with regulatory requirements, most commonly 21 CFR Part 11. Data validation ensures no data is duplicated and that invalid data is not collected. This is often automatic within the system, preventing data that doesn’t meet all the defined parameters and formats from entering the database. 
 Query management: Given the complexity of clinical trials, multiple personas and stakeholders are involved in the process from start to finish. Query management features allow users in the EDC system to communicate with each other, raise and respond to questions, and address any issues with data before it is locked and finalized. Specific queries can be built into the system to trigger approval workflows, but manual queries can also be raised. 
 Role-based permissions: EDC software allows users to be assigned permissions based on their role, depending on if they are a site coordinator, data monitor, or another party. This promotes data security and integrity and reduces the likelihood of data tampering or breaches. 
 Data reporting: Data can be visualized and accessed in various formats, including dashboards, graphs, charts, and exported sheets. EDC software allows data to be imported or exported in several formats, and analytics helps measure ongoing trial outcomes. This data can be shared across different trial sites, and automatic updates can be configured in the system to send out triggers based on time or event.

Question 3

What are the Benefits of Electronic Data Capture (EDC) Software?

Accepted Answer

The following are the benefits of EDC software: 
 Improved data quality: Electronic data capture (EDC) software promotes data quality by eliminating outdated paper systems, which slow down trials. Duplicate and invalid data could take weeks to identify before electronic systems were introduced. An EDC system allows these issues to be raised and resolved in real time and even avoided entirely depending on how the parameters for valid responses to eCRFs are built.  
 Quicker data collection: By consolidating data from multiple sources into one system, EDC software allows sites to complete trials quicker. Forms can be built and deployed faster, data entry is streamlined, querying and validation are resolved in real time, and data can be locked by the appropriate users—all within one system. Data can also be accessed much faster by searching within the database, allowing faster decisions to be made and for trials to be adapted as needed. EDC software unifies the various working parts that go into ideating and conducting clinical trials.  
 Improved data security and compliance: EDC software promotes security standards that protect sensitive health data by offering audit trails, role-based permissions for data access, and built-in regulatory compliance standards (which may include 21 CFR part 11 compliance, GDPR compliance, and ISO 27001-2013 compliance). Data access is limited based on user type, and designated trial protocols ensure adherence to data integrity throughout the data collection process. Additionally, EDC vendors ensure data is protected and backed up, with more now offering cloud storage.
