Sleep deprivation is a multifactorial phenomenon, occurring frequently in the intensive care unit (ICU) and linked to adverse patient healthcare outcomes. The key practice question of this project focused on determining if retiming of routine laboratory and imaging testing outside of the designated “quiet time” can improve sleep quality among adult patients in the ICU. The purpose was to evaluate the effectiveness of implementing an evidence-based intervention to improve sleep quality in the ICU setting. The theoretical framework was the plan-do-study-act model, which offered a process for implementing a practice change and reevaluation of the intervention’s sustainability within the organization. A thorough literature search of over 100 scholarly journal articles, book references, and expert scholarly reports was completed to gain an understanding of this phenomenon in the ICU setting. The Richards-Campbell Sleep Questionnaire (RCSQ) was the data collection tool used to measure improvement in sleep quality. There were 72 participants that are included in the project. The Wilcoxon rank sum and chi square tests were used for the statistical analysis. The findings did not show statistical significance in the improvement in the RCSQ scores after implementation of the intervention. The recommendations include sleep deprivation training for nursing staff and providers, routine use of the RCSQ for data collection, and repeating the study with an increased number of participants and redefined inclusion and exclusion criteria to be more representative of the ICU patient population. The implication for social change is that this project empowers nursing to embrace a leadership role in using evidence-based practice to change clinical guidelines and improve patient outcomes.
