Public preferences on written informed consent for low‐risk pragmatic clinical trials in Spain

摘要

AimsPragmatic randomized clinical trials (pRCTs) collect data that have the potential to improve medical care significantly. However, these trials may be undermined by the requirement to obtain written informed consent, which can decrease accrual and increase selection bias. Recent data suggest that the majority of the US public endorses written consent for low‐risk pRCTs. The present study was designed to assess whether this view is specific to the US.
