The study aims to clarify the sources and influencing factors of noise in the post anesthesia care unit, as well as the perception of noise by medical staff through survey table, in order to improve the noise environment, optimize noise management, protect medical staff, and enhance medical quality.
Study Type
OBSERVATIONAL
Enrollment

No intervention measures
Main noise decibel
The level of noise decibel in the post anesthesia care unit when the number of patients is between half and three-quarters of the total number of beds. Using noise vibration measuring instrument (AWA5688, Hangzhou Aihua Instrument Co., Ltd.) to measure the noise decibel.
Time frame: From enrollment to the end of observation at 1 week
Secondary noise decibel
The level of noise decibel in the post anesthesia care unit when the number of patients is not between half and three-quarters of the total number of beds. Using noise vibration measuring instrument (AWA5688, Hangzhou Aihua Instrument Co., Ltd.) to measure the noise decibel.

Subjective perception of noise by medical personnel
Using multiple-activity scale for hyperacusis (MASH) that is proposed by Dauman in 2005 to evaluate emotion. MASH categorizes the level of annoyance caused by noise into five levels: absent, mild, moderate, substantial, and severe. In our study, every individuals will be given a score of zero to four based on this five levels, higher scores mean a worse outcome.
Time frame: From enrollment to the end of observation at 1 week
The impact of noise on the work of medical personnel
Based on our preliminary research findings, we have made a questionnaire titled "Working Conditions in Noisy Environments", which indicates that the impact of noise in the post anesthesia care unit on the work of medical personnel is usually as follows: no impact, failure to hear patient calls or needs in a timely manner, inability to identify alarms from specific medical equipment, need to speak loudly, and throat discomfort.
Time frame: From enrollment to the end of observation at 1 week
The source of noise as perceived by the medical staff
Based on our preliminary research findings, we have made a questionnaire titled "Noise source in Post Anesthesia Care Unit", which includes monitor, sputum suction device, ventilator, conversation, mobile phone, printer, outdoor factors (such as the move of transfer beds.), and other.
Time frame: From enrollment to the end of observation at 1 week
Satisfaction of medical staff with the current noise situation
Based on our preliminary research findings, we have made a questionnaire titled "Satisfaction with the Current Noise Situation in the Post Anesthesia Care Unit", which includes very satisfied, satisfied, general,dissatisfied, and very dissatisfied.
Time frame: From enrollment to the end of observation at 1 week
