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

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.

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.

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).

Postoperative noise control improves psychological status, sleep quality, and wound healing, warranting clinical promotion.
