Pilot study of a preventive multicomponent nurse intervention to reduce the incidence and severity of delirium in hospitalized older adults: MID-Nurse-P.

Background: Although multicomponent interventions are the gold standard for delirium management, few nurse-led interventions in Acute Geriatric Units (AGU) are described.

Objectives: To analyze if a preventive multicomponent non-pharmacologic nurse-led intervention randomized clinical trial (MID-Nurse Study) is feasible (pilot study), and can reduce the incidence, duration, and severity of delirium in hospitalized older adults in an AGU.

Design: Parallel-group double-blind randomized clinical trial (pilot Study).
