Reduce MRSA bloodstream infections that people get in the hospital — HAI‑02 Data Methodology and Measurement

About the National Data

Data

Baseline: 1.00 was the national Standardized Infection Ratio (SIR) for hospital-onset MRSA bacteremia infections in 2015

Target: 0.50 SIR

Numerator
Observed number of hospital-onset MRSA bacteremia infections.
Denominator
Predicted number of hospital-onset MRSA bacteremia infections.
Target-setting method

Maintain consistency with national programs, regulations, policies, or laws

Target-setting method details
N/A
Target-setting method justification
The target was selected to align with the National Action Plan to Prevent Healthcare-Associated Infections (HAI): Road Map to Elimination. This plan used a consensus driven process across federal HAI subject matter experts to identify a target.

Methodology

Methodology notes

SIR is risk adjusted for facility bed size, inpatient community-onset prevalence rate, and medical school affiliation. The SIR compares the actual number of HAIs at each hospital, the predicted number of infections; anything above a 1.0 SIR would indicate more infections than expected while anything less than 1.0 SIR would be considered less infections than expected.

Data collected by the CDC are also used by CMS as part of their hospital quality program. Hence, the data collected for this Healthy People 2030 objective are consistent with national hospital quality policies set forth by CMS. Likewise, these data are also used to monitor progress in CDI prevention for the HHS National Action Plan to Prevent HAIs.

History

Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.
