The impact of universal face masking and enhanced hand hygiene for COVID-19 disease prevention on the incidence of hospital-acquired infections in a Taiwanese hospital.

OBJECTIVES

During the coronavirus disease 2019 (COVID-19) pandemic, strict infection control measures have been implemented in healthcare settings and hospitals, including respiratory and hand hygiene. This study investigated the impact of these control measures on the incidence rates of hospital-acquired infections (HAI) and multidrug-resistant organisms (MDRO) in a Taiwan medical center.

METHODS

This study compared the consumption of personal prevention resources and the incidence density of HAI and MDRO in a medical center in Taiwan from January to May 2020, encapsulating the COVID-19 outbreak period in the study, to baseline data from the same timeframe in 2018 and 2019.

RESULTS

There was no significant difference between the number of inpatient days in 2020, 2018 and 2019. The consumption of either alcohol for hand hygiene or surgical masks significantly increased in 2020. However, the overall HAI incidence density did not significantly differ from the rate at the baseline period. It was found that the incidence density of MDRO was significantly lower in 2020, especially in carbapenem-resistant Acinetobacter baumannii and vancomycin-resistant Enterococcus.

CONCLUSIONS

A collateral benefit of the COVID-19 prevention measures on the incidence density of MDRO was observed in a hospital in Taiwan where the incidence of COVID-19 was low.
