Abstract

Purpose/Objectives:

The aims of this study were to determine the feasibility of and test a multicomponent, nonpharmacologic, nurse-driven intervention for prevention of delirium.

Design:

This was a prospective, cohort pilot study.

Setting:

This study was carried out in a 12-bed medical intensive care unit in a Magnet-designated community hospital in a major metropolitan city in the Southwest United States.

Sample:

A convenience sample of consented patients meeting inclusion criteria was included in this study.

Methods:

A multicomponent prevention protocol consisting of sedation cessation, sleep-wake cycles, sensory stimulation, mobility, and music was tested.

Findings:

Capturing data for the interventions was problematic. Insufficient documentation systems and inadequate multidisciplinary participation in carrying out the protocol, especially mobility, were barriers.

Conclusions:

There was little difference in the proportion of delirium before and after intervention. Success in the identification and prevention of delirium requires a multidisciplinary approach.

Implications:

Further research is needed using a larger sample size. Refinement of a mobility program is needed.
