Dataset Information

Non-circadian signals in the intensive care unit: Point prevalence morning, noon and night.

ABSTRACT:

Background

Intensive care unit (ICU) sleep disturbance is severe and potentially related to abnormal light and sound exposure.

Objectives

To assess the prevalence of measures of light and sound disturbance in ICU patient rooms, and whether these could be modified by a sleep-promotion intervention.

Methods

This observational study with a before and after design for a quality improvement initiative surveyed environmental factors in ICU rooms at 01:00 08:00, and 12:00. Surveys assessed light usage, television usage, window shade position, and room door/curtain position. Factors were compared before and after an ICU sleep-promotion intervention.
