The Effect of A Quality Improvement Intervention on Perceived Sleep Quality and Cognition in a Medical ICU

In this study, the authors sought to determine if a multifaceted quality improvement initiative could improve sleep and delirium at a tertiary academic medical center. 300 adult patients, who spent one at least one night in the medical ICU, were evaluated for perceived sleep quality, ICU noise levels and delirium free days. The authors discovered that their multi-staged quality improvement project was easy to implement and resulted in reduced noise ratings, decreased incidence of delirium and coma, and increased daily delirium and coma free status. Improvements in perceived sleep did not reach statistical significance. Despite the lack of improvement in perceived sleep, the author’s multi-disciplinary multifaceted approach seemed to have merit with regards to improving delirium and coma.
