Abstract

Sleep is very important and necessary for human health. For patients undergoing surgery, they should have good sleep to restore both physiological and psychological health. This has a positive impact on the process of recovering damaged tissues, helping to heal wounds earlier, preventing complications, shortening the length of hospital stay, and reducing treatment costs.

Objectives: This study was conducted to examine the quality of sleep and identify associated factors in patients who underwent surgery at the General Surgical Ward, Tay Nguyen Regional General Hospital.

Research subjects and methods: A cross-sectional descriptive study was performed on 374 postoperative patients who met the sampling criteria and randomization. Data was collected through the interview technique using a structured questionnaire. Sleep quality was assessed by the Pittburgh Sleep Quality Index instrument.

Results: 78.1% postoperative patients had poor sleep quality with mean score of PSQI scale was 10.3 (range: 0-21; SD= 3.27). Most of the patients had a subjective assessment of sleep quality at fairly bad (27.8%) and very bad (41.7%). Age group is one of the non-environmental factors associated with sleep quality in this population. Environmental factors, including lighting in the patient's room, activities of medical staff, and noise from equipment, are associated with the patient's sleep quality (p < 0.05).
