Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Main noise decibel
Time Frame: From enrollment to the end of observation at 1 week
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.
From enrollment to the end of observation at 1 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Secondary noise decibel
Time Frame: From enrollment to the end of observation at 1 week
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.
From enrollment to the end of observation at 1 week
Area of post anesthesia care unit
Time Frame: From enrollment to the end of observation at 1 week
Measure the area of the post anesthesia care unit using a tape measure, in square meters.
From enrollment to the end of observation at 1 week
Number of beds of post anesthesia care unit
Time Frame: From enrollment to the end of observation at 1 week
From enrollment to the end of observation at 1 week
Medical personnel allocation situation
Time Frame: From enrollment to the end of observation at 1 week
Number of anesthesiologists and nurses
From enrollment to the end of observation at 1 week
Staying time in post anesthesia care unit of patients
Time Frame: From enrollment to the end of observation at 1 week
From enrollment to the end of observation at 1 week
Number of patients with or without tracheal intubation retained
Time Frame: From enrollment to the end of observation at 1 week

Time Frame: From enrollment to the end of observation at 1 week
From enrollment to the end of observation at 1 week
Working years of medical staff
Time Frame: From enrollment to the end of observation at 1 week

Subjective perception of noise by medical personnel
Time Frame: From enrollment to the end of observation at 1 week
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.
From enrollment to the end of observation at 1 week
The impact of noise on the work of medical personnel
Time Frame: From enrollment to the end of observation at 1 week
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.
From enrollment to the end of observation at 1 week
The source of noise as perceived by the medical staff
Time Frame: From enrollment to the end of observation at 1 week
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.
From enrollment to the end of observation at 1 week
Satisfaction of medical staff with the current noise situation
Time Frame: From enrollment to the end of observation at 1 week
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.
