Inclusion criteria

Inclusion criteria: Patients who participated in the previously conducted study at Kindai University Hospital entitled 'Prevalence Survey of Sleep Disturbance Immediately After Surgery'(Ethics Committee approval number: R07-049) will be included. Specifically, the study population will consist of adult patients who, in the prospective observational study, underwent elective surgery under general anesthesia, returned to a general ward after surgery, and underwent subjective sleep assessment of the first postoperative night using the Richards Campbell Sleep Questionnaire (RCSQ) on the morning of postoperative day 1. In the present study, among these patients, cases for which the information required for this study, including C-reactive protein (CRP), neutrophil percentage, and lymphocyte percentage on postoperative day 1, can be obtained from medical records, anesthesia records, nursing records, and blood test results will be included in the analysis.
