Summary
The investigators propose a multicenter, randomized, double-blinded, placebo-controlled trial to study the effect of additive low-dose haloperidol prophylaxis on top of exciting care in a general population of older patients (age 70 years and over) acutely admitted to the hospital through the emergency department (ED) for general medicine and surgical specialties, and who are at-risk for developing in-hospital delirium on admission according to the VMS delirium risk questions (one or more positive answers out of three questions). The investigators hypothesize that this intervention will reduce the incidence of in-hospital delirium as well as duration and severity of delirium.Phase:
