About

The implementation of environmental intervention program reduced the duration of delirium and length of stay at the ICU in critically-ill surgical patients.

Full description

Purpose: Delirium occurs among patients in intensive care unit at high rates and increases the risk for morbidity and mortality. The purpose of this study is to investigate the effects of environmental interventions for the prevention of delirium.

The environmental intervention included cognitive assessment, providing orientation and comfortable environment, and a proper sleeping environment. The primary outcomes were the incidence rate of delirium, time of delirium onset, and the duration of delirium.
