Factors that affect sleep quality: perceptions made by patients in the intensive care unit after thoracic surgery
Menée dans une unité de soins intensifs à partir de questionnaires auprès de 40 infirmières et 152 patients ayant subi une chirurgie thoracique pour traiter un cancer, cette étude identifie les facteurs affectant la qualité du sommeil et analyse les différences de perception entre patients et infirmières vis-à-vis de ces facteurs
Objective : This study identifies factors affecting sleep patterns among thoracic surgery patients in the intensive care unit (ICU) and compares the perceptions of sleep-disturbing factors between nurses and patients. Methods : One hundred and fifty-two patients and 40 nurses were surveyed using the Pittsburgh Sleep Quality Index (PSQI) and self-designed questionnaires (for patients and nurses). All statistical analyses were carried out by SPSS, and the following statistical methods were used to evaluate the data: chi-squared test and logistic regression. Results : Of 152 patients, 46.1 % reported poor sleep quality during their hospitalization; their PSQI total score was 6.95 ± 3.713. Of these, 69.1 % indicated that their sleep quality was poorer than before; 50.0 % of them changed their sleep patterns. Significant discrepancies exist between nurses and patients in the perceptions of sleep-disturbing factors of patients. Conclusion : Thoracic surgical patients’ perceptions of their sleep in the ICU indicate poor sleep quality, which is decided by a variety of disturbing factors. Perceptions of these factors varied greatly between surveyed patients and nurses.
