An Evaluation of Time Spent Completing Electronically Collected Patient-Reported Outcomes in Clinical Trials

Patient-reported outcomes (PROs) are important measures of efficacy in the context of clinical trials but are sometimes identified as time and resource intensive to study participants and site personnel. The objective of this research was to evaluate the amount of time that participants spend completing PROs via an electronic device in phase 2 and 3 clinical trials across several disease areas.

The electronic Clinical Outcome Assessment (eCOA) data were obtained from Johnson & Johnson clinical trials across various disease areas from 2016 to 2023. Data were acquired from internal and external sources including clinical trial sites and eCOA partners. In total, 82 trials were analyzed, containing data from 33,633 unique participants, and 1,083,994 measurements of completed electronic PRO instruments. After data cleaning, descriptive and multivariate analyses were performed. Electronic PRO completion time was examined in two ways: by time-per-item and time-per-instrument for each PRO.

On average, participants spend about 16 s per item and an average of 2 min to complete a PRO instrument electronically. The average time to complete PRO instruments varied significantly by disease area and most eCOA were completed on study site tablets (68%) or personal handheld devices (31%).

Overall, patients spend an average of 16 s per item and 2 min per PRO instrument in clinical trial studies. PROs are a crucial component of clinical trial outcomes data and can be efficiently completed electronically by participants in clinical trials in a short amount of time.
