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).

Interventions

OTHERafter-each-case room disinfection

After-each-case room disinfection was defined as after completing each case.

OTHERdaily room disinfection

Daily room disinfection was defined as disinfection after completing 8 non-general anesthesia gastroscopy or 4 general anesthesia gastroscopy.
