Impact of Postoperative Noise Reduction on Anxiety, Depression, and Sleep Quality in Patients with Extensive Burns Undergoing Skin Grafting

Objective: This study aimed to investigate the effects of postoperative noise control on anxiety, depression, and sleep quality in patients with extensive burns undergoing skin grafting. Methods: A retrospective analysis was conducted on 148 patients with burns (May 2022–December 2024), including 73 in the regular group (standard care) and 75 in the noise control group (noise-reducing caring method). Outcomes included noise levels, emotional states [Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA)], sleep quality [Pittsburgh Sleep Quality Index (PSQI)], Numeric Rating Scale (NRS), wound healing, and nursing satisfaction. Results: Following the caring method, the noise reduction group showed significantly lower HAMD scores (13.25 ± 1.10 vs. 17.73 ± 2.01, P < 0.001) and HAMA scores (12.50 ± 1.60 vs. 16.49 ± 1.32, P < 0.001) compared with the regular group. The PSQI scores were significantly lower in the noise reduction group (4.55 ± 1.02 vs. 7.16 ± 1.24, P < 0.001). The daytime and nighttime ward noise levels in the noise reduction group were 42.15 ± 3.28 and 32.47 ± 2.91 dB, respectively, which were significantly lower than those in the regular group (50.62 ± 4.11 and 40.85 ± 3.74 dB, respectively, P < 0.001). Additionally, the noise reduction group had a higher skin graft survival rate (78.25% vs. 72.48%, P = 0.023), shorter graft survival time (26.85 ± 2.12 vs. 30.12 ± 2.56 days, P < 0.001), and higher nursing satisfaction (94.67% vs. 80.82%, P = 0.010). Conclusion: Postoperative noise control improves psychological status, sleep quality, and wound healing, warranting clinical promotion.
