Several hospitals are using traffic light indicators to make staff more aware of their noise levels. When noise escalates, the traffic light changes from green to yellow; and when noise is too loud, the light turns red. Other hospitals have noise reduction campaigns in place.
"[The campaigns] are not only a satisfier for patients, but our staff is happy about having some more restful periods as well," said Tom Moore of the University of Iowa Hospitals.
Dr. Vineet Arora of the University of Chicago, who studies the sleep quality of patients in the hospital setting, says "we need to generalize the findings [of this study] to real patients in an actual hospital setting" and change the culture of the hospital where "patients are empowered to talk to their doctors about their sleep needs."
The hope is that when patients have a quiet environment where they can sleep and heal, patient outcomes may improve. When the dial on hospital noise is turned down, Solet says, "we can expect decreased lengths of stay and lower rates of re-admission."
