CARAlert Annual Report: 2021
The National Alert System for Critical Antimicrobial Resistances - CARAlert - Annual Report for 2021 is available.
The 2021 Annual Report provides the results of analyses of data on confirmed critical antimicrobial resistances (CARs) submitted to the National Alert System for Critical Antimicrobial Resistances (CARAlert) for 2021, and trend data for 2017 to 2021. Key findings include:
- There was an overall 18% decrease of CARs reported in 2021 compared to 2020
- The most frequently reported CAR in 2021 was Carbapenemase-producing Enterobacterales (CPE) which is of concern as it poses a significant risk to patient safety given its high level of resistance
Trends in CARs reported between 2017 and 2021 may have been affected by the response to the COVID-19 pandemic in 2020 and 2021, particularly for community-onset CARs and CPE, which trended downward in 2020 and 2021, compared with 2017 to 2019.
