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

The Efficacy Comparing Daily and After-each-case Room Disinfection in the Endoscopy Unit During the COVID-19 Pandemic.

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.

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).

Inclusion Criteria:

• All the cases received gastroscopy.

Exclusion Criteria:

• High-risk personal through contact history, symptoms, body temperature, COVID-19 virus nucleic acid testing and chest computed tomography (CT) scan.
