Overview

To examine the effects of haloperidol, chlorpromazine, valproic acid and placebo, in conjunction with standardized non-pharmacologic interventions, in the first line treatment of agitated delirium in hospitalized patients with cancer. This double-blind, randomized clinical trial aims to provide evidence on various therapeutic options for palliating delirium, thereby reducing delirium-related distress and ultimately alleviating suffering.

Objectives: Primary objective: Compare the effect of scheduled haloperidol, chlorpromazine, valproate and placebo (non-pharmacological interventions alone) on the frequency of breakthrough restlessness over 72 hours in patients with agitated delirium seen by the palliative care consultation team. Our working hypothesis is that haloperidol, chlorpromazine, and valproate will lead to fewer episodes of breakthrough restlessness than placebo. Secondary Objective #1: Compare the effects of scheduled haloperidol, chlorpromazine, valproate and placebo on (1) RASS-PAL, (2) need for dose escalation, (3) perceived comfort by caregivers and bedside nurses, (4) delirium severity (Memorial Delirium Assessment Scale), (5) delirium-related distress in caregivers and nurses (Delirium Experience Questionnaire), (6) delirium recall in patients (Delirium Recall Questionnaire), (7) symptom expression (Edmonton Symptom Assessment Scale), (8) adverse effects, and (9) survival. Our working hypothesis is that haloperidol, chlorpromazine, and valproate are superior to placebo (non-pharmacologic interventions alone) in improving delirium-related outcomes. Secondary Objective #2: Estimate the efficacy of non-pharmacologic interventions alone on breakthrough restlessness. Our working hypothesis is that patients in the placebo group will require fewer breakthrough doses in the 72 hours after implementation of non-pharmacological interventions
