The Efficacy Comparing Daily and After-each-case Room Disinfection.

Study Overview
=================
Brief Summary
-----------------
The aim of our study was to evaluate the difference of effectiveness between daily and after-each-case room disinfection in the endoscopy unit during the COVID-19 pandemic.

Detailed Description
-----------------
This study divided into 2 groups: daily room disinfection and after-each-case room disinfection. Each group was also subdivided into general anesthesia or non-general anesthesia gastroscopy, and with or without ventilation consultation room. Samples collection include: operation unit air (six-stage sieve percussion air sampler for sampling, airflow rate 28.3L/min, sampling time 4 min); workstation's mouse (wiping sterile cotton for sampling); endoscopist's gown, control panel buttons, and patient's bed headboard (contact plate for sampling).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: daily room disinfection<br>Room disinfection was defined as the cleansing and disinfection of the surface of the facility, endoscopist's gown, and air in the endoscopy room after the examination. Specifically, sanitizing wipes wiped the surface of the facility one by one, containing quaternary ammonium salt, alcohol, and interfacial activator; the air disinfection machine continued for 30min of air disinfection. Daily room disinfection was defined as disinfection after completing 8 non-general anesthesia gastroscopy or 4 general anesthesia gastroscopy. | Other: daily room disinfection<br>* Daily room disinfection was defined as disinfection after completing 8 non-general anesthesia gastroscopy or 4 general anesthesia gastroscopy.<br>|
| Experimental: after-each-case room disinfection<br>Room disinfection was defined as the cleansing and disinfection of the surface of the facility, endoscopist's gown, and air in the endoscopy room after the examination. Specifically, sanitizing wipes wiped the surface of the facility one by one, containing quaternary ammonium salt, alcohol, and interfacial activator; the air disinfection machine continued for 30min of air disinfection. After-each-case room disinfection was defined as after completing each case. | Other: after-each-case room disinfection<br>* After-each-case room disinfection was defined as after completing each case.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Qualified rate of room disinfection | The samples of workstation's mouse, control panel buttons and patient's bed headboard greater than 10 CFU/cm2, samples of endoscopist's gown greater than 200 CFU/suit, and samples of operation unit air greater than 500 CFU/m3 are deemed as an unacceptable level of bioburden. | 48 hours | 
| The number of colony-forming units (CFU) | The number of colony-forming units (CFU) of operation unit air, workstation's mouse, endoscopist's gown, control panel buttons, and patient's bed headboard. | 48 hours |
