1.3 Measure Description

Standardized Infection Ratio (SIR) and Adjusted Ranking Metric (ARM) of healthcare-associated, central line-associated bloodstream infections (CLABSI) will be calculated among patients in bedded inpatient care locations.
This includes acute care general hospitals, long-term acute care hospitals, rehabilitation hospitals, oncology hospitals, and behavioral health hospitals.

        • 1.14 Numerator

          Total number of observed healthcare-associated CLABSI among patients in bedded inpatient care locations.

        • 1.15 Denominator

          Total number of predicted healthcare-associated CLABSI among patients in bedded inpatient care locations, calculated using the facility’s number of central line days and the following significant risk factors: 
          • Acute Care Hospitals: CDC location, facility bed size, medical school affiliation, facility type, birthweight category (NICU locations only)
          • Critical Access Hospitals: no significant risk factors, calculation based intercept only model
          • Inpatient Rehabilitation Facilities: Proportion of admissions with stroke, proportion of admissions in other non-specific diagnostic categories
          • Long Term Acute Care Hospitals: CDC location type , facility bed size, average length of stay, proportion of admissions on a ventilator, proportion of admissions on hemodialysis

        • Exclusions

          Data from patients who are not assigned to an inpatient bed are excluded from the denominator counts, including outpatient clinics, 24-hour observation units, and emergency department visits. Inpatient rehab locations and inpatient psychiatric locations that have their own Centers for Medicare and Medicaid Services (CMS) Certification Number (CCN) are excluded.
