HAI’s Increase During COVID-19 Pandemic

 

 

The COVID-19 pandemic appears to have reversed the previous trend toward decreases in HAI’s (hospital-associated infections). Researchers used data from the National Healthcare Safety Network (NHSN), the nation’s largest HAI surveillance system, to analyzed recent trends in HAI’s (Weiner-Lastinger 2021). Early in 2020 there was a slight decrease in HAI’s compared to the same period in 2019. Then the pandemic hit. The remainder of 2020 saw significant national increases in CLABSI’s (central line–associated bloodstream infections), CAUTI’s (catheter-associated urinary tract infections), VAE’s (ventilator-associated events), and MRSA infections compared to 2019.

 

CLABSI’s, which had actually decreased 12% in the first quarter of 2020, increased 46% to 47% in the third quarter and fourth quarters of 2020 compared to 2019.

 

CAUTI’s increased significantly with the fourth quarter increasing by 19% compared to 2019.

 

VAE’s had significant increases nationally in all 4 quarters of 2020 compared to 2019, with the largest increase of 45% occurring in Q4.

 

MRSA bacteremia saw increases of 23% and 34% during 2020-Q3 and 2020-Q4 compared to 2019.

 

Decreases in SSI’s (surgical site infections) in 2020 likely reflected a substantial decrease in the number of adult inpatient colon or abdominal hysterectomy procedures (the 2 types of surgery included in the data) done during the pandemic.

 

Interestingly, C difficile–associated infections (CDI) decreased throughout 2020 compared to 2019. The authors attributed the decrease in CDI to increased focus on hand hygiene, environmental cleaning, patient isolation, and use of PPE during 2020, combined with continued inpatient antimicrobial stewardship programs and a marked decline in outpatient antibiotic prescribing,

 

It really should come as no surprise that HAI’s would increase during the pandemic. The increase in COVID-19 hospitalizations have put an incredible strain on hospital resources. Many more patients required intensive care, with increased use of ventilators. The authors also note that a longer patient length-of-stay, additional comorbidities and higher patient acuity levels, and a longer duration of device use in 2020 could have contributed to an overall increased risk of a device-associated infection during the pandemic. They also note that some studies identified an increased risk of ventilator associated conditions in critically ill COVID-19 patients

 

One would also suspect that PPE shortages, staffing shortages, burnout, and increased patient burden were likely factors contributing to the increase in most of these HAI’s.

 

The resurgence of COVID-19 infections and hospitalizations in 2021, driven by emergence of the delta variant, forbodes continued high levels of HAI’s.
