The National Healthcare Safety Network (NHSN) is the nation’s most widely usedhealthcare-associated infection surveillance system.

• Antimicrobial Use and Resistance (AUR) Module
• Dialysis Event Surveillance Protocol
• Long-term Care Facility Component Respiratory Pathogens  Module

Healthcare facilities collect and report data on healthcare-associated infections (HAIs)to NHSN using standardized definitions. HAI data are used for a variety of purposes,which may include, satisfying reporting mandates, comparing infection rates between andwithin healthcare facilities, providing consumers with information, guiding policies andprocedures, evaluating the effectiveness of interventions, and conducting research.

Surveillance data can be categorized into Process Measures or Outcome Measures.

Process Measures

Measures adherence to recommended practices that may affect outcomes.

Process measures have a 100% target adherence rate and are a more direct measure ofquality and outcome. These measures apply to a variety of healthcare settings and oftenreflect promotion of evidence-based best practices to improve patient outcomes orquality of care.

Examples: Hand hygiene compliance rate, adherence to cleaning catheter hubs and injectionports before access, percentage of environmental cleanings completed appropriately.

Outcome Measures

Measures actual results.

Outcome measures have variable goals and often require risk adjustment. These measuresallow you to see whether changes are leading to improvement such as reducing andpreventing HAIs. These measures may not be collected in all healthcare settings and maynot involve direct care or provider accountability.

Example: CLABSI, CAUTI, and SSI SIRs

Standardized Infection Ratio (SIR)

Purpose: The primary summary measure used by NHSN to trackhealthcare-associated infections at a national, state, or facility level over time.

Calculation: number of observed infections / number of predictedinfections.

Interpretation:

• If SIR > 1.0, more infections were observed than predicted.
• If SIR > 1.0, less infections were observed than predicted.
• If SIR = 1.0, the same number of infections were observed as predicted.

Standardized Utilization Ratio (SUR)

Purpose: A risk-adjusted measure used to compare device utilization atthe national, state, or facility level by tracking central line, urinary catheter, andventilator use.

Calculation: number of observed device days / number of predicted devicedays.

Interpretation:

• If the SUR < 1.0, fewer device days were reported than predicted.
• If the SUR = 1.0, the same number of device days were observed as predicted.
• If the SUR > 1.0, more device days were observed than predicted.
• The SUR is designed to be a high-level indicator of device use and should not be used to draw conclusions around whether devices are overused or underused.
• The SUR should be used in conjunction with the SIR.

Cumulative Attributable Difference (CAD)

Purpose: A risk-adjusted measure that indicated the number of infectionsthat must be prevented within a group, facility, or unit to achieve an HAI reductiongoal

Calculation: (number of observed infections) — (number ofpredicted infections*SIRgoal)

Interpretation:

• A positive CAD is the number of excess infections a facility would have needed to prevent to achieve an HAI reduction goal during a specified time.
• A negative CAD means the facility has reached or surpassed the HAI reduction goal.
• Usually presented as a whole number.

Standard Antimicrobial Administration Ratio (SAAR)

Purpose: A standardized metric of antimicrobial use for specifiedpatient care locations.

Calculation: number of observed antimicrobial days / number of predictedantimicrobial days.

Interpretation:

• If the SAAR>1.0, more antimicrobial used was observed than predicted.
• If the SAAR <1.0, less antimicrobial use was observed than predicted.
• If the SAAR = 1.0, the same antimicrobial use was observed as predicted.
• A SAAR is not a definitive measure of appropriateness or judiciousness of antimicrobial use, and any SAAR value may warrant additional investigation.
