Firstly though, what is an ePRO?
Patient-Reported Outcomes (PROs) are the data patients provide about their health, symptoms, treatment effect, and overall quality of life. The PRO data used to be collected on paper questionnaires or face-to-face at the clinic interviews. However, these methods were time-consuming and could be affected by memory bias or errors in reporting.
The PRO’s digital sibling, the ePRO, changes the game by using electronic devices like smartphones, tablets, or web platforms to collect this PRO data. Patients now complete assessments or questionnaires on their phones or tablets, providing investigators with real-time data.
