Correlation between APACHE III score and sleep quality in ICU patients

摘要

Objective To reveal the correlation between APACHE III score and sleep quality in patients in the intensive care unit (ICU). Methods This prospective, observational study included patients aged ≥18 years, who had been admitted to an integrated ICU for ≥48 h. Age, sex, Pittsburgh Sleep Quality Index (PSQI) prior to ICU, Numeric Rating Scales (NRS), noise, illumination, number of nursing interventions, Richards Campbell Sleep Questionnaire (RCSQ), and APACHE III score during sleep were evaluated. Results A total of 124 ICU patients were included, all with APACHE III scores?&?60. APACHE III scores were not significantly associated with RCSQ scores. There were significant inverse associations between sleep quality in the ICU and PSQI score prior to ICU (odds ratio [OR] 0.587, 95% confidence interval [CI] 0.365, 0.945) and noise (OR 0.628, 95% CI 0.522, 0.756). Conclusion In ICU patients with APACHE III scores below 60 points, APACHE III score was not associated with sleep quality. PSQI score prior to ICU and noise were significantly inversely associated with sleep quality in this ICU patient population.
