The Influence of Neonatal Intensive Care Unit Design on Sound Level

Author(s): Chen, H.-L., Chen, C.-H., Wu, C.-C., Huang, H.-J., Wang, T.-M., Hsu, C.-C.
Preterm infants receiving care in neonatal intensive care units (NICUs) are especially susceptible to adverse effects caused by excessive noise. Previous studies indicate that the physical designs of NICUs themselves hold a large influence over the overall noise level.

Adapting to Family-Centered Hospital Design: Changes in Providers’ Attitudes over a Two-Year Period

Author(s): France, D., Throop, P., Joers, B., Allen, L., Parekh, A., Rickard, D., Deshpande, J.
Although hospitals are being designed based on evidence-based design principles, it’s unclear how working in such an environment influences providers’ attitudes and professional performance.

Patients’ Perception of Music versus Ordinary Sound in a Postanaesthesia Care Unit: A Randomized Crossover Trial

Author(s): Fredriksso, A., Hellstrom, L. & Nilsson, U.
A healing environment helps patients refocus from negative stimuli to something pleasant and familiar, allowing them to escape into ‘‘their own world.” One feature of such an environment might be soothing music, an intervention that can help patients focus their awareness on the music and help in relaxation. Music is also closely linked to emotions and arousal.

The Effect of Environmental Design on Reducing Nursing Errors and Increasing Efficiency in Acute Care Settings: A Review and Analysis of the Literature

Author(s): Chaudhury, H., Mahmood, A., Valente, M.
In acute care settings, the physical environment plays an important role in staff efficiency and patient safety. Some research suggests that poor environments can result in staff stress, anxiety, and distractions due to noise; artificial lighting; improper or inadequate ventilation; and disorienting layouts of nursing units. There is less research on how environmental factors affect nursing staff health, effectiveness, errors, and job satisfaction.

Clinical review: The impact of noise on patients’ sleep and the effectiveness of noise reduction strategies in intensive care units

Author(s): Xie, H., Kang, J., Mills, G. H.
The World Health Organization recommends that noise levels in hospitals stay below 30 dBA at night to allow for better rest, yet excessive noise is prevalent in many healthcare settings, including intensive care units (ICUs). Research indicates that, since the 1960s, noise levels in hospitals increased by an average of 0.38 dBA (day) and 0.42 dBA (night) per year. Other research reports that the noise level in ICUs ranges from 50 to 75 dBA, with a night peak level soaring to 103 dBA. It’s easy to see why sleep disturbance is common among these vulnerable patients.

Using Rapid Assessment to Evaluate Noise on an In-Patient Unit

Author(s): Deitrick, L.M., Kennedy, P., Cyriax, C., Davies-Hathen, N.
Research shows that many hospitals are noisy from a variety of sources: people, environment, and machines. Further, this excessive noise can have negative effects on patients and staff including lost sleep, higher blood pressure, lower overall patient satisfaction, increased readmission rates, and increased employee stress levels.

Effect of Sacred Space Environment on Surgical Patient Outcomes: A Pilot Study

Author(s): Schmock, B. N., Breckenridge, D. M., Benedict, K.
With the growing trend to patient-centered care, nurses are often tasked to evaluate how care is delivered. The perioperative environment is highly technical in nature and is often perceived as cold, while creating a sense of fear in patients. This study's purpose was to create an alternative healing environment (termed a sacred space and comprised of both environmental and nurse behavioral factors) compared to the traditional environment for surgical patients in the operating room (OR).
