Effect of Noise Reduction Methods in the ICU on Sleep Quality

Sleep deprivation is a common problem in the intensive care unit because it can increase rates of delirium, impede proper recovery, lead to longer hospital stays, and increase health care costs. This study aims to review three randomized controlled trials that observe the effect of noise reduction methods in improving sleep quality among intensive care patients. One study compared rates of delirium among those use earplugs and those who do not. Two other studies found that interventions such as earplugs, eye masks, and melatonin have proven to improve sleep quality. While interventions such as earplugs may be uncomfortable for some patients, it is reasonable it to at least offer these products to those who may want it. This can in turn improve patient satisfaction rates, decrease hospital length of stays and reduce healthcare costs. Moreover, these interventions are safe, cost effective, and easy to implement.Faculty advisor: Jill P Berg, Ph.D., Professor Emeritus (jpberg@uci.edu) - Program in Nursing Scienc
