Environmental Intervention on Delirious Patients

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

Detailed 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. Methods: A total of 192 patients who had been admitted to the surgical intensive care unit (SICU) in Asan Medical Center during the pre-intervention period (Jun 2013 to Oct 2013) and the post-intervention period (Jun 2014 to Oct 2014) was enrolled and prospective cohort study was done. 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.
