In the realm of clinical trials and patient registries, the use of Electronic Patient-Reported Outcomes (ePRO) has gained significant traction in recent years.

The advancements in technology have revolutionized the way patients can conveniently complete surveys, leading to more efficient and accurate data collection.

This article explores the evolution of ePRO and its benefits for both researchers and patients.

The Importance of ePRO in Clinical Trials

Electronic PRO has emerged as a preferred method for collecting patient-reported data due to its ability to yield higher quality data compared to traditional paper-based diaries.

Studies have shown that ePRO can elicit significantly greater subject compliance, sometimes as high as 97% [1].

Unsupervised paper-based self-reports often result in untimely, unreadable, missing, or faulty data.

In contrast, ePRO allows for real-time data collection and validation, reducing the possibility of lost, missing, and non-compliant data.

The use of timestamps in ePRO also ensures accurate documentation of data entries.

Benefits of ePRO for Researchers and Patients

Enhanced Data Quality and Compliance

One of the key advantages of ePRO is its ability to improve compliance and enhance the overall quality of data collected.

Paper-based surveys are prone to errors such as incomplete, unreadable, or inappropriate data entries, which can be time-consuming and costly for researchers to rectify.

In contrast, ePRO systems provide user-friendly interfaces that guide patients through the survey process, minimizing errors and ensuring complete and accurate data collection.

The real-time validation of data entries in ePRO also allows for immediate identification and resolution of any issues, further enhancing data quality.

Improved Patient Experience and Enrollment

ePRO systems offer convenience and flexibility to patients, allowing them to participate in clinical trials regardless of their geographical location.

This ease of participation can lead to increased patient enrollment and retention in studies.

Patients can access ePRO surveys through downloadable mobile apps on their smartphones or tablets, eliminating the need for frequent visits to the doctor’s office.

The user-friendly interface of ePRO platforms makes it easier for patients, including those who are less tech-savvy, to navigate and complete surveys.

Real-Time Monitoring and Insights

With ePRO, researchers can monitor patient-reported data in real-time, enabling timely interventions and adjustments to treatment plans if necessary.

This real-time monitoring allows for quicker insights into patient outcomes, facilitating more effective decision-making and potentially improving patient outcomes.

Researchers can also automate calculations and perform real-time statistical analyses using ePRO platforms, simplifying data visualization and making it easily actionable.

Privacy and Security

Ensuring patient privacy and data security is of utmost importance in any data collection process.

ePRO systems prioritize the confidentiality and security of patient-reported data.

These platforms employ encryption methods to protect sensitive information and comply with regulatory requirements, including 21 CFR Part 11.

By implementing user permissions and access restrictions, ePRO platforms ensure that patients can only view their own forms, while researchers have visibility of all patient data

The Role of ePRO Software

To facilitate the efficient and effective implementation of ePRO, various software solutions have been developed.

Let’s discuss some key features of these software applications.

Configurable Questionnaires and User-Friendly Interface

ePRO applications allow sponsors to create new questionnaires or choose from a validated disease-specific PRO library.

These software tools provide a user-friendly interface with simple page layouts and chronological response mechanisms, enhancing the patient experience and minimizing errors.

Clear and unambiguous error messages further contribute to a seamless data collection process.

Patient Engagement Features

Some ePRO platforms offer various patient engagement features to improve participation and compliance.

These solutions allow for the setup of response-driven push notifications or emails to remind patients to report their outcomes at the right time.

Additional tools such as welcome and thank you notes, newsletters, and interim training can be integrated to further engage patients throughout the study.

Secure and Encrypted Data Collection

ePRO platforms ensure security and privacy of patient-reported data.

Most vendors in the market guarantee that all ePRO data is encrypted and compliant with regulatory requirements, providing researchers and patients with peace of mind.

The Future of ePRO and Data Collection

The shift from paper-based to electronic PRO data collection has revolutionized the way patient-reported outcomes are captured and analyzed in clinical trials.

The use of ePRO systems has proven to enhance data quality, improve patient experience, and provide real-time insights into patient outcomes.

As technology continues to advance, further innovations in ePRO systems are expected.

The integration of artificial intelligence and machine learning algorithms may enable more efficient data analysis and interpretation, leading to personalized treatment approaches based on patient-reported outcomes.

Additionally, the continued emphasis on patient-centered care and shared decision-making will drive the demand for reliable and user-friendly ePRO platforms.


In conclusion, ePRO has emerged as a valuable tool in clinical trials and patient registries, enabling efficient and accurate data collection.

The use of ePRO systems enhances data quality, improves patient experience, and provides real-time insights for researchers.

The future of ePRO and data collection holds great promise for advancing clinical research and improving patient outcomes.
