Multimodal sleep management reduces perioperative insomnia in general surgery patients through optimal healing...

This quality improvement study analyzed factors influencing situational insomnia among perioperative patients in general surgical wards using a combination of literature review, questionnaire surveys, and group discussions. Guided by the Optimal Healing Environment (OHE) model, which emphasizes creating a healing atmosphere through internal, external, and interpersonal factors, we developed a multi-modal sleep management program. Key components included standardizing sleep assessment protocols, optimizing the environment through noise reduction strategies (e.g., noise sensors) and light control (e.g., light-reducing films), implementing staff behavior modifications such as "Quiet Hour" protocols, and providing patient and family education. Post-implementation, the incidence of situational insomnia decreased significantly from 66.4% to 35.5%, noise levels during midday and nighttime were reduced by 21.5% and 28.0%, respectively, and patient satisfaction with noise and temperature management improved by 38.7% and 20.3%, respectively. These results highlight the effectiveness of the OHE-based program in improving sleep quality, accelerating recovery, and enhancing patient satisfaction in general surgery settings.
