Survey results emphasize need for flexibility in strategies.
The following is the second installment of a two-part series evaluating the use of backup solutions for electronic patient-report outcomes (ePRO) systems. Here, C-Path’s Electronic Clinical Outcomes Assessment (eCOA) Consortium presents results from a survey issued to 15 sponsors who are members of C-Path’s PRO Consortium and have a specific interest in eCOA systems. Twelve responses were received. The survey investigated backup solution adoption, justifications for solution selection, reasons why paper persists, and how backup data are evaluated.
When asked about their general approach to backup solutions:
The primary electronic backup solution of choice for those that employ them was a web backup. Paper remains prevalent and is often used in combination with a web backup.
Interestingly, web backups are not used in isolation in our sample. Multiple respondents indicated that web backup is not always accessible; limited connectivity or device availability could be factors, and even if accessible, the web-based solution may still be challenging for specific participant populations and/or assessments. In such cases, sponsors have used alternative methods such as bring your own device (BYOD), interviewer administration of assessments, replacement devices, and/or paper. Early discussions with clinical teams and sites to identify situations that necessitate a more flexible or tiered backup approach is advised (e.g., the combination of web and BYOD).
As indicated, paper backup is used by some sponsors as a primary backup solution. Based on the survey, paper backup is mostly used to support site-based ePRO collection. The principal reasons for use were:
Most respondents agreed data captured via backup methods should be identified as such in the dataset. It was unclear from responses if sponsors uniformly conducted sensitivity analyses prior to pooling these data. Further discussion on backup data is necessary; it is important to know if sponsors see differences in the data and how they assess the relative level of quality between the data. It is evident from the survey that respondents consider it to be critical to reduce the amount of missing data; and employ a variety of backup solutions to ensure data completeness.
Although not generalizable beyond the survey respondents, the results indicate that there is no universal solution. Strategies may adapt to the trial’s endpoint hierarchy, therapeutic area, and accessibility, and there is some desire for multiple options within a trial. Part 1 of this series suggested that with more flexible eCOA solutions, we may reduce the need for backups, specifically paper. Following the survey, we continue to champion the concept of flexibility. Respondents also acknowledged that what is planned is not always executed within the study. Clinical teams need immediate access to options such as web-based backup, BYOD, or replacement devices in order to pivot as needed, but this demands continued evolution of the eCOA systems used, inclusive of innovation in science, technology, device management, and technical support.
