Delirium is a frequent condition in the Intensive Care Unit (ICU) with no existing evidence-based treatment. The aim of the AID-ICU study is to assess the benefits and harms of haloperidol treatment for the management of ICU acquired delirium.


Delirium among critically ill patients in the intensive care unit (ICU) is a common condition associated with increased morbidity and mortality. No evidence-based treatment exist of this condition. Haloperidol is the most frequently used agent to treat ICU-related delirium, but according to the available literature there is no firm evidence of efficacy and safety of this intervention. AID-ICU aims to assess the benefits and harms of haloperidol in adult, critically ill patients with delirium in the ICU.
