Abstract
Problem - It has been found that up to 80% of all mechanically ventilated ICU patients experience delirium (Ali, 2022). ICU delirium is an alteration in normal circadian rhythms while hospitalized which leads to confusion and mood abnormalities. To maintain circadian rhythms, it is important to maintain sleep and wake cycles, as well as sleep hygiene.
Purpose – The purpose of this study is to explore if patients who receive daily circadian rhythm interventions, such as maintaining pre-admission sleep patterns, have reduced rates of ICU delirium compared to those who receive standard care.
Methods – A mixed methods, quasi-experimental design will be used. Participants will be patients, ages 20-50, admitted to a 50-bed ICU unit. The study will compare pre-admission sleep patterns, CAM-ICU, and RASS assessments of patients receiving daily circadian rhythm interventions to those who do not receive it.
Conclusion – Interventions to maintain the circadian rhythm and sleep schedule of ICU patients should be used to prevent ICU delirium (Li et al., 2023). Further studies on prevention of ICU delirium including pharmacological and nonpharmacological interventions should be explored in future research to improve patient health.
