Indicator Report Data View Options

Why Is This Important?

Healthcare-associated infections are among the top causes of unnecessary illnesses and deaths in the United States.[ ^1^]


Infections that are acquired in a health care setting, as measured by a standardized infection ratio (SIR) A standardized infection ratio (SIR) lower than 1.0 means the actual number is lower than expected.[[br]] A standardized infection ratio (SIR) higher than 1.0 means the actual number is greater than expected. All objectives and data are for hospitals only. Ambulatory surgery centers are not included.

Data Notes

This is HNJ2020 Objective HAI-4.

Data Source

Healthcare-Associated Infections, National Healthcare Safety Network (NHSN), Centers for Disease Control and Prevention

How the Measure is Calculated

  • Numerator:

    Total number of "observed" or actual infections
  • Denominator:

    Total number of "expected" infections (derived from the national baseline)

Data Issues

New baselines were calculated by CDC in 2015. As a result, SIRs for 2016 and subsequent years may be higher than those for 2010-2015.[[br]] Due to the COVID-19 pandemic, acute care hospitals were only required to submit data during the second half of 2020.
