Condition(s) targeted: Delirium; Critical Illness

Intervention: Haloperidol (Drug)

Phase: Phase 2

Status: Completed

Sponsored by: University of Colorado, Denver

Official(s) and/or principal investigator(s):
Ivor S Douglas, MD, Principal Investigator, Affiliation: University of Colorado Department of Pulmonary and Critical Care Medicine

Summary

The goal of this study is to determine whether haloperidol reduces the time on the breathing machine in critically ill patients with delirium.

Clinical Details

Official title: A Randomized Prospective Pilot Study Of Haloperidol In Addition To Standard Sedation In Mechanically Ventilated Patients With Delirium

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Ventilator-free days out of the first 28

Secondary outcome:

Duration of delirium

Length of hospitalization

Cost of hospitalization

28-day mortality

Usage of other sedatives

Serum markers of delirium (neuron-specific enolase and protein S-100B)

Cognitive-function scores at the time of ICU discharge, hospital discharge, and six-month follow-up

Detailed description: Delirium is a frequent end-organ complication of critical illness and is an independent predictor of mortality in mechanically ventilated patients. However, management of delirium is a major therapeutic challenge and it is unknown if current therapies are disease modifying or function only as symptom management. Haloperidol has been demonstrated to reduce delirium in retrospective studies. This study is a pilot prospective randomized clinical trial in the Denver Health Medical ICU to determine if haloperidol in addition to an evidence-based standard-of-care sedation protocol for the management of delirium results in a shortened duration of intubation and improvements in post-extubation cognitive status. The haloperidol dose is administered using titration-protocol guided by nursing assessment of delirium using the confusion assessment method for the ICU (CAM-ICU). The primary outcome is ventilator-free days out of the first 28, and secondary outcomes include duration of delirium, length and cost of hospitalization, 28-day mortality, usage of other sedatives, serum markers of delirium (neuron-specific enolase and protein S-100B), and cognitive-function scores at the time of ICU discharge, hospital discharge, and six-month follow-up. The goal of the 20-patient pilot is demonstrating safety of the haloperidol protocol, as evaluated by an independent data-safety monitoring board. Following approval of the DSMB, 122 more patients will be enrolled in the full RCT to achieve power for an 80% chance of detecting a 40% decrease in duration of intubation with P < 0. 05.
