Adverse events registration in clinical trial participants with severe acute brain injury: a Delphi consensus study

A new tool for registration of adverse events and reactions in trial participants with severe acute brain injury was reviewed and refined by a Delphi panel of 10 Nordic neurocritical-care experts. The intention is to enhance the transparency, accuracy and consistency of reporting harms in clinical trials. Through thorough and standardized recording, the tool has the potential to improve the overall quality of clinical trials.
