The University of Virginia Health System inpatient satisfaction survey identified noise as the most important irritant to surgical inpatients. Analysis of the level and pattern of noise on patient floors and intensive care units was done with baseline measurements followed by then two separate interventions: 1) education of nursing and physician staff 2) closing patient room doors. A decibel meter (M-27 Dosimeter) recorded the noise level over 24 hours. Patients doors were open in the initial measurements. Next, three 1-hour education sessions were conducted by a surgeon and nursing supervisor to review noise-reduction strategies with the staff. These included using pagers in vibrate mode, minimizing overhead announcements, and conducting nurse reports and physician teaching sessions in classrooms away from the nurses' station. Finally, the doors were closed except as visitors and staff entered the room. Little impact was seen from staff education. Closing patient doors on surgical floors decreased noise an average of 6.0 dB, a change that patients can readily perceive. Conversely, intensive care unit patients are exposed to more noise with closed doors, presumably because most noise emanates from equipment within the room. A policy of closing patient floor room doors may increase patient satisfaction.
弗吉尼亚大学医疗系统的住院患者满意度调查显示，噪音是外科住院患者最重要的困扰因素。对病房楼层和重症监护病房的噪音水平及模式进行了分析，先进行了基线测量，随后采取了两项单独的干预措施：1）对护理人员和医生进行培训；2）关闭病房门。使用分贝仪（M - 27剂量仪）记录24小时内的噪音水平。在初始测量时病房门是打开的。接下来，一名外科医生和护理主管开展了三场为时1小时的培训课程，与工作人员回顾减少噪音的策略。这些策略包括将传呼机设置为振动模式、尽量减少广播通知，以及在远离护士站的教室进行护士汇报和医生教学课程。最后，除了访客和工作人员进入病房时，病房门保持关闭。工作人员培训的效果甚微。在外科楼层关闭病房门平均可使噪音降低6.0分贝，这种变化患者能够明显感觉到。相反，重症监护病房的患者在病房门关闭时会接触到更多噪音，可能是因为大部分噪音来自房间内的设备。关闭病房楼层病房门的政策可能会提高患者满意度。
