Trials with patient reported endpoints are reporting increased efficiencies when using electronic patient reported outcomes (ePRO), compared to paper diary data collection methods. To date, approximately 20% of all trials with patient reported endpoints are using ePRO solutions to collect efficacy data. As the adoption of electronic patient reported outcomes continues to increase, sponsors are finding new ways to justify this technology’s ROI, and identify the types of trials that are best suited to ePRO (versus paper). This article will describe how several market-leading sponsors have quantified the benefits of better data quality, with case examples from recent trials implemented by PHT Corporation (PHT). These analyses are provided with the intention to inform the clinical research community, and provide the frameworks for further ROI determinations.

Attributable, legible, contemporaneous, The FDA has reviewed ePRO vs. PRO, and cites Trials with patient-reported endpoints– original and accurate (ALCOA) patient data that unsupervised data entry as a major drawback whether in home or in medical offices–report is complete and time-stamped through the use to paper reported outcomes.
