What is one factor that can lead to financial attrition in clinical trials?

Travel expenses are a significant factor that can lead to financial attrition in clinical trials. Participants often incur costs related to traveling to the trial site, which may include transportation, lodging, and meals. If these expenses become burdensome or if participants are not compensated for them, they may choose to withdraw from the study.

In many cases, trials may not fully account for the financial strain that travel expenses can impose on participants, particularly for those who may have limited financial resources. As a result, ensuring that participants are aware of and can manage these costs is crucial for maintaining enrollment and retention throughout the trial.

While inadequate participant training, loss of interest, and miscommunication about trial benefits can affect participant engagement and retention, the direct financial burden posed by travel expenses is a specific and tangible factor that can lead participants to exit a study, thereby impacting the overall trial results and its success.
