: Good sleep quantity and quality are essential for patient recovery while in the intensive care unit (ICU). Patients commonly report poor sleep while in the ICU, and therefore, identifying the modifiable factors that patients perceive as impacting their sleep is important to improve sleep and recovery. This study also assessed night-time light and sound levels in an ICU in an effort to find modifiable factors. : A total of 137 patients (51F) aged 58.1 ± 16.8 years completed a survey including questions about their sleep before and during their ICU stay, factors contributing to poor sleep in the ICU, and perceived factors that may have improved their sleep in the ICU. Night-time light and sound levels were measured in patient rooms and nurses' stations. : Patients reported poorer sleep quantity and quality while in the ICU compared to home. Among the most common reasons for poor sleep, easily modifiable factors included noise (50.4%) and lights (45.3%), potentially modifiable factors included pain (46.7%), and non-modifiable factors included IV lines (42.3%). Patients felt their sleep would have been improved with interventions such as dimming lights (58.4%) and closing doors/blinds at night (42.3%), as well as potentially implementable interventions such as a sleeping pill (51.8%). Overnight sound levels in bedrooms were above the recommended levels (40 dB) and light levels averaged over 100 lux. : Sleep quality and quantity were both worse in ICU than at home. Modifiable factors such as sound and light are common factors that patients perceive impact their sleep in the ICU. Readily implementable sleep management strategies aimed at minimizing the impacts of sound and light levels in the ICU are ways to improve patients' sleep in the ICU.
在重症监护病房（ICU）期间，良好的睡眠数量和质量对患者康复至关重要。患者普遍报告在ICU期间睡眠不佳，因此，识别患者认为会影响其睡眠的可改变因素对于改善睡眠和康复很重要。本研究还评估了ICU中的夜间光线和声音水平，以努力找出可改变因素。
共有137名年龄为58.1±16.8岁的患者（51名女性）完成了一项调查，其中包括关于他们在ICU住院前和住院期间的睡眠问题、导致ICU睡眠不佳的因素以及可能改善他们在ICU睡眠的因素。在病房和护士站测量了夜间光线和声音水平。
与在家时相比，患者报告在ICU期间的睡眠数量和质量较差。在睡眠不佳的最常见原因中，易于改变的因素包括噪音（50.4%）和光线（45.3%），可能可改变的因素包括疼痛（46.7%），不可改变的因素包括静脉输液管（42.3%）。患者认为，通过调暗灯光（58.4%）、夜间关门/拉上百叶窗（42.3%）等干预措施，以及服用安眠药（51.8%）等可能可行的干预措施，他们的睡眠会得到改善。卧室的夜间声音水平高于推荐水平（40分贝），光线水平平均超过100勒克斯。
ICU中的睡眠质量和数量均比在家时差。声音和光线等可改变因素是患者认为会影响其在ICU睡眠的常见因素。旨在尽量减少ICU中声音和光线水平影响的易于实施的睡眠管理策略是改善患者在ICU睡眠的方法。
