Haloperidol for Delirium in Adult Critically Ill Patients — EuRIDICE  

Critical Illness Clinical Trial

Official title: Efficacy of Haloperidol to Decrease the Burden of Delirium in Adult Critically Ill Patients (EuRIDICE): a Prospective Randomised Multi-center Double-blind Placebo-controlled Clinical Trial

Status Terminated

Clinical Trial Summary

The EuRIDICE trial will study whether haloperidol as a first line treatment for ICU delirium reduces delirium duration (and severity). Adverse outcomes typically associated with delirium will also be studied and include long term cognition, functional outcome and quality of life. Further, patient and family experiences and cost-effectiveness will be assessed. Finally, safety concerns associated with the use of haloperidol in this vulnerable population will be studied.

Clinical Trial Description

BACKGROUND. Although widely used, the efficacy and safety of haloperidol for delirium in critically ill adults remain unclear. A randomised controlled trial is warranted to study the effect of haloperidol on delirium or coma, long-term outcomes, safety concerns, and cost-effectiveness.

SUMMARY.

The investigators will perform a multi-center, randomised, double-blind, placebo-controlled clinical trial to evaluate the use of haloperidol for delirium treatment in 742 critically ill adults with delirium. Days spent without delirium- or coma in the first 14 days after randomisation is the primary outcome. Study drug will be initiated at 2.5mg IV q8h and increased after 24 hours to 5mg IV q8h if delirium persists. Study drug dose will be tapered when delirium has resolved during 24 hours. All patients will be managed with a standardized pain, agitation and delirium protocol. Standard operating procedures for agitation (analgesia titration, alpha2 agonists) and hallucination management (atypical antipsychotics) will be implemented to accommodate possible imbalances of these symptoms in both treatment arms. Open-label haloperidol administration is discouraged during the trial. The sample size provides a power of 90% to detect statistically significant results (p<.05) and a true treatment difference of one day for the primary outcome between trial arms.

This trial is expected to answer the clinically relevant question whether haloperidol still deserves a place in ICU delirium management. The primary outcome (delirium- and coma-free days) will be related to the secondary outcomes cognitive dysfunction, functional and psychological outcomes and patient- and family experiences. An extensive cost-effectiveness analysis will be done. Mortality at one year and safety concerns of haloperidol (QTc prolongation on EKG and rigidity) will be assessed as secondary endpoints. In conclusion, this large multicentre trial will assess efficacy and safety of haloperidol for ICU delirium. ;
