Psychiatric ward design can reduce aggressive behavior

TL;DR: A conceptual model proposing that aggression in psychiatric facilities may be reduced by designing the physical environment with ten evidence-grounded stress-reducing features was tested in a newer hospital in Sweden having wards with nine of the ten features.

Healing built-environment effects on health outcomes: environment–occupant–health framework

TL;DR: There was no adequate framework that could integrate existing research findings holistically under a holistic conceptual evaluative framework, and an environment–occupant–health (E-O-H) framework is proposed, taking a holistic perspective to identify and evaluate different HBE characteristics.
Journal ArticleDOI

Reducing hospital ICU noise: a behavior-based approach.

TL;DR: The results of this study indicate that behavioral modification alone is not adequate to control excessive noise and there is a need for further research involving the supportive involvement by clinicians, ICU staff, along with effective medical device alarm management, and continuous process improvement methods.
Journal ArticleDOI

Improvement of intensive care unit sound environment and analyses of consequences on sleep: an experimental study

TL;DR: Noise in ICUs impairs sleep and the reduction of maximal A-weighted levels from 64 to 56dB is not enough to have a clear improved effect on sleep quality, so the effects of reduced maximum sound level were minor.
Journal ArticleDOI

Analysis of the soundscape in an intensive care unit based on the annotation of an audio recording.

TL;DR: The soundscape of an ICU was evaluated and it was suggested that most of the noise sources in ICUs may be associated with modifiable human factors.

Notes on Nursing: What It Is, and What It Is Not

TL;DR: This chapter discusses Florence Nightingale's vision of Nursing Theory and Health, and some of the principles of that theory can be applied to modern nursing practice.

Abnormal sleep/wake cycles and the effect of environmental noise on sleep disruption in the intensive care unit.

TL;DR: ICU patients are qualitatively, but not necessarily quantitatively, sleep deprived; and although environmental noise is in part responsible for sleep-wake abnormalities, it is not responsible for the majority of the sleep fragmentation and may therefore not be as disruptive to sleep as the previous literature suggests.

The effects of noise on man.

TL;DR: In this paper, a book on noise effects on man covering audiometry, aural reflex, hearing damage risk, physiological responses, motor performance and speech communication is presented, with a focus on the effects of noise.
