6 Advantages of ePRO (“electronic Patient Reported Outcome”)

For clinical research managers who have always conducted their studies on paper or using spreadsheets such as Excel, there is sometimes a level of distrust towards cloud-based solutions. The cost of electronic data capture (EDC) subscription and ePRO solutions can appear daunting at first. In addition, many are hesitant to commit additional time and money towards workforce training in new software systems. 

A new level of technical documentation

Since systems such as paper or spreadsheets are cost-inefficient, unsafe, and likely to struggle in the digital era, we can expect a surge in companies moving their technical documentation into the cloud – and this includes solutions such as EDC and ePRO (Electronic patient-reported outcomes)

Studies show that electronic participant reporting in clinical research yields higher quality data and better participation rates than paper-based diaries. As the world shifts towards a focus on patient empowerment, self-reported data by patients will play an increasingly important role in clinical data collection. ePROs, as the name suggests, are electronically collected patient-reported outcomes. Research shows that ePRO elicits a significantly greater subject compliance, sometimes as high as 97%

Playbook: 5 Success Factors for ePRO Solutions in Clinical Studies

  • Electronic patient-reporting provides much higher data quality and better participation rates
  • ePRO supports you in complying to regulations and offers you flexible reporting options as well as simultaneous use with different users and roles
  • In this free playbook, we present five success factors for the use of ePRO solutions in clinical trials

What are the benefits of EDC and ePRO solutions?

So, if you’re on the fence about choosing an electronic solution for conducting your clinical trials in the future, consider the following advantages of EDC and ePROs for managing studies rather than spreadsheets and pen and paper.

1. Improved regulatory compliance and a trackable audit trail

An audit trail that details the reasons for change throughout your data collection is a powerful part of maintaining regulatory compliance. For medical device manufacturers in particular, with the EU MDR, no class of product is exempt from maintaining up-to-date pre- and post-market data collection for acquiring and keeping its CE mark. Many EDC systems and ePROs have an audit trail feature, while paper-based and spreadsheet often make it difficult to track data changes. EDC systems that have been validated by a third-party audit can help eliminate any concerns you may have about the compliance of your data.

2. Error detection and prevention

Data entry mistakes resulting from human error are inevitable, but edit checks are completely  absent in paper-based data collection methods. Although Excel formulas offer an elementary level of validation, missing or incorrect data may still be overlooked. This can result in the loss of significant time and resources in larger scale studies. Reading patients’ handwriting on paper forms can also be a struggle, so allowing them to enter their data electronically through an ePRO or eSurvey will significantly speed up the process and allow for data to be fed directly into the system, rather than manually entered by medical staff. EDC systems also enable you to incorporate conditional actions directly into eCRFs, firing queries and sending targeted notifications when any user-defined event has occurred, such as (serious) adverse events, new enrolments, or protocol deviations. 

3. Flexible reporting options 

Manual reporting is a huge drawback of paper-based data management. The more complex the report, the more difficult, time-consuming and costly the corresponding resources you’ll need to invest. EDC solutions such as Climedo can help create automatic skip patterns, restrict the range of possible responses, and set automatic filters on answers to apply exclusions / inclusions etc. This level of assurance cannot be achieved with a paper survey or using spreadsheets, where the breadth and depth of reporting options is limited. Once built, eSurveys and eDiaries can be modified and reused in multiple formats, saving you time on an otherwise tedious task.  

4. Enhanced data security 

Potential data security risks represent an understandable concern across the clinical research industry. Advanced EDC solutions provide role-based security functionality, making permissions and user roles highly configurable to ensure that only authorized people within the study have access to the data which is relevant to them – a functionality which is close to  impossible with paper- or Excel-based questionnaires. Furthermore, EDC is one of the safest solutions for clinical research, providing it is implemented using the highest level of data security (ISO 27001, HIPAA), data pseudonymization, offsite backups, and SSL encryption.

5. Multi-user and multi-role simultaneous data entry 

Paper-based solutions do not allow multiple stakeholders to work with the same data simultaneously. Further, operating with multiple spreadsheets, documents, and versions can lead to discrepancies and misplaced data. A cloud-based EDC empowers several team members to manage data at the same time. Users can benefit from realtime tracking and viewing, which is virtually unachievable via spreadsheet or paper. With an ePRO solution, study subjects can also electronically access forms and input their data, thus giving them more control over their study participation and creating improved patient engagement.  

6. Enhanced capabilities 

Data management with Excel or on paper means that you’re only capable of simple data entry and revision. Climedo’s EDC and ePRO solutions offer you access to a wide range of functionalities such as randomization, scheduling, product tracking, normal lab ranges etc. Not only do these enhance the level of reporting, but also allow data analysis results to feed into company strategies, ranging from clinical development to powerful product marketing claims.
