Participant perspectives on management and communication of incidental findings identified on radiographic imaging performed during a clinical research trial: A single site pilot study

Abstract

Background: Incidental findings (IFs) in radiographic imaging are unexpected discoveries unrelated to the purpose of the scan. While the protocol for communicating IFs is better defined for clinical providers, little formal guidance on communicating IFs identified on research scans to participants is available. This study explored participants' experience with communication and management of IFs found on imaging identified in a clinical research trial.

Methods: Participants who completed the parent clinical trial, which included imaging, were invited to participate. A survey, developed by the study team, was administered telephonically, and consisted of multiple choice and open-ended questions.

Results: Thirty participants enrolled in the survey study. Ninety-three percent of all participants (with and without IFs) reported they would participate in another research study to learn information that was important to their health. Seventeen participants reported being notified about an IF on their study scan(s). Ninety-four percent of those participants with an IF were satisfied with how the IF was communicated, and 71 % were grateful to find out about a health problem before it became an issue. Forty-one percent reported that learning about the IF led to improved health. Content analysis of the data from the open-ended questions revealed categories and themes which enriched the quantitative data.

Conclusion: Participants generally wanted to know when an IF was discovered unexpectedly on their imaging scan, as they learned important information about their health. Findings underscore the importance of having a clear protocol for communicating IFs to research study participants that undergo evaluation with radiographic imaging.
