From The Impact of COVID-19 on HAI Incidence

• Impact of COVID-19 on HAIs: A summary of data reported to NHSN Presents comparisons to pre-pandemic (2019) national and state quarterly standardized infection ratios (SIRs) for central line-associated bloodstream infection (CLABSI), catheter-associated urinary tract infection (CAUTI), ventilator-associated events (VAE), surgical site infection (SSI), methicillin-resistant Staphylococcus aureus (MRSA) bacteremia LabID, and Clostridioides difficile infection (CDI) LabID from acute care hospitals.

From the National and State Healthcare-Associated Infections Progress Report

• At the national level, among acute care hospitals there was 3% statistically significant decrease in CDI between 2020 and 2021 and significant increases in all other HAI types but SSI following colon surgeries. Statistically significant increases were observed for MRSA (14%), VAE (12%), SSI-HYST (11%), CLABSI (7%) and CAUTI (5%) between 2020 and 2021.
• Highlights of 2021 state performance compared to the 2015 national baseline SIR of 1:
  • 49 states performed better on at least two infection types
  • 11 states performed worse on at least two infection types

See: Current HAI Progress Report for more information about national and state-level HAI data, measured using the standardized infection ratio (SIR).

A Comparison between the Impact of COVID-19 on HAIs in 2020 paper and the National and State HAI Progress Report

• The COVID-19 Impact paper and the 2020 HAI Progress Reports are two important publications that describe HAI incidence amid the COVID-19 pandemic in 2020. The objective of these publications and the methods used in the analyses are different from each other. The comparison document [PDF – 1 page] summarizes the methods used in the COVID-19 Impact paper and the 2020 HAI Progress Report. The COVID-19 Impact Paper is a one-time study that reviews the impact of COVID-19 on the HAI reporting and incidence by comparing the quarterly 2020 SIRs for consistent reporters to their 2019 quarterly SIRs, while the 2020 HAI Progress Report is an annual report that assesses the changes in 2020 annual data compared to 2019. Additional measures are included in each publication.

From the HAI Hospital Prevalence Survey

• On any given day, about 1 in 31 hospital patients has at least one healthcare-associated infection. Patients in the 2015 HAI Hospital Prevalence survey were at least 16% less likely than patients in the 2011 survey to have an HAI.
  • 3% of hospitalized patients in the 2015 survey had one or more HAI.
  • There were an estimated 687,000 HAIs in U.S. acute care hospitals in 2015. About 72,000 hospital patients with HAIs died during their hospitalizations.
