Stratification by risk category

Annual standardized infection ratio (SIR) of bloodstream infections (BSIs) among children and adults receiving maintenance hemodialysis at outpatient hemodialysis facilities. BSIs are defined as positive blood cultures for hemodialysis patients which are reported monthly by participating facilities. The SIR is reported for a yearly period (calendar year) and is calculated by dividing the number of observed BSIs by the number of predicted BSIs during the year.

This is a measure of follow-up clinical visits for patients with chronic conditions who have experienced an acute exacerbation of one of six conditions (eight categories) of interest (coronary artery disease [CAD] {high or low acuity}, hypertension {high or medium acuity}, heart failure [HF], diabetes, asthma, and chronic obstructive pulmonary disease [COPD]) and are among adult Medicare Fee-for-Service (FFS) beneficiaries who are attributed to entities participating in the CMMI Accountable Care Organization (ACO) Realizing Equity, Access, and Community Health (REACH) model.
