What is electronic patient-reported outcomes (ePRO)?


ePRO stands for “Electronic Patient-Reported Outcomes.” It is a tool that allows patients to record electronically and submit their health outcomes digitally using devices such as smartphones, tablets, or computers. Electronic patient-reported outcomes (ePRO) is an innovative tool that transforms how data is collected and analyzed in clinical trials. 


Technology plays an increasingly crucial role in the ever-evolving landscape of clinical trials. According to an industry report, the global ePRO market is projected to reach $2.9 billion by 2026, indicating the growing recognition of the importance of this technology. Regulatory agencies, such as the US FDA, also encourage using ePRO to improve the quality and efficiency of clinical trials.


We will explore the world of ePRO in depth, examining its advantages, and valuable insights for professionals looking to implement ePRO in their clinical trials.

What is ePRO?

ePRO allows patients to report their experiences and health outcomes directly through electronic devices like smartphones or tablets. This technology has numerous benefits, including:


  • Increased accuracy and reliability of data
  • Reduced costs and time delays
  • Improved patient experience
  • Enhanced patient adherence and compliance

Benefits of Electronic Patient-Reported Outcomes (ePRO) in Clinical Trials

The use of ePRO offers numerous advantages for both patients and clinical research organizations:


  • Increased convenience for patients: Patients can record their data anytime, anywhere, reducing the burden and travel time.
  • More accurate and complete data: Electronic devices eliminate transcription errors and improve consistency.
  • Greater efficiency for researchers: ePRO automates the data collection process, saving time and resources.
  • Improved patient adherence: Regular reminders and notifications help patients comply with study protocols.

Electronic Patient-Reported Outcomes (ePRO) Value for Pharmaceutical and Clinical Research Organizations

ePRO is invaluable for pharmaceutical companies and clinical research organizations conducting clinical trials. It allows for:

  • Collecting high-quality data from patients
  • Improving efficiency and reducing costs
  • Accelerating the drug development process
  • Improving patient outcomes

Who Uses ePRO and Why?

ePRO is definitely a game-changer for everyone involved in clinical trials. Let’s break down who uses it and why it matters:


  • Imagine reporting your health updates from the comfort of your couch! ePRO lets you record information on your phone or tablet whenever it works for you. Electronic entries mean no more worries about typos messing up the data. Patients also get helpful reminders and learn more about the study, making you feel more in control of your participation.

Clinical Trial Sites:

  • Less paperwork: ePRO automates data collection, allowing clinic staff to focus on what they do best – caring for patients. It also reduces errors and keeps everything consistent, smoother the whole process. With helpful reminders. It´s a win-to-win strategy for healthcare professionals and patients.

Sponsors (Pharmaceutical Companies):


  • Drug Development: ePRO helps gather reliable patient data efficiently, speeding up the drug development. This means new treatments can potentially reach those who need them sooner. On top of that, ePRO can help keep costs down, which is always a bonus.

Contract Research Organizations (CROs):

  • Smoother Trials: ePRO tools streamline data collection for CROs, making managing clinical trials a breeze. It also helps ensure everything meets regulatory guidelines and keeps the data secure. By offering ePRO solutions, CROs become even more valuable partners for pharmaceutical companies.


  • What is ePRO? It’s a digital tool allowing patients to report health outcomes on smartphones, tablets, or computers.
  • Benefits: ePRO offers increased accuracy, reduced costs, improved patient experience, and better adherence.
  • Benefits for Patients: Convenience (reporting from anywhere), reduced travel, fewer errors, and access to helpful information.
  • Benefits for Clinical Trial Sites: Less paperwork, reduced errors, smoother data collection, and improved patient retention.
  • Benefits for Sponsors: Faster drug development due to efficient data collection, potentially leading to quicker access to new treatments for patients.
  • Benefits for CROs: Streamlined trial management, easier adherence to regulations, and secure data collection, making them more competitive partners.
