Statistical risk model

This measure estimates a hospital-level, risk-standardized readmission rate (RSRR) of unplanned, all-cause readmission within 30 days of discharge from an index admission with an eligible condition or procedure. The measure reports a single summary RSRR, derived from the volume-weighted results of five different models, one for each of the following specialty cohorts based on groups of discharge condition categories or procedure categories: surgery/gynecology, general medicine, cardiorespiratory, cardiovascular, and neurology.

For dual eligible beneficiaries age 18 years and older, state-level observed and risk-adjusted rates of hospital admissions for ambulatory care sensitive conditions (ACSC) per 1,000 beneficiaries for ACSC by chronic and acute conditions. This measure has three rates reported as both observed and risk-adjusted rates:
• Chronic Conditions Composite
• Acute Conditions Composite
• Total (Acute and Chronic Conditions) Composite

This hybrid measure estimates a hospital-level, 30-day risk-standardized mortality rate (RSMR) for patients discharged from the hospital with a principal discharge diagnosis of acute ischemic stroke. Mortality is defined as death from any cause within 30 days of the index admission date for stroke patients.

This measure estimates a hospital-level 30-day, all-cause, risk-standardized mortality rate (RSMR) for patients discharged from the hospital with a principal discharge diagnosis of acute myocardial infarction (AMI). The outcome is all-cause 30-day mortality, defined as death from any cause within 30 days of the index admission date, including in-hospital death, for AMI patients. The target population is Medicare Fee-for-Service beneficiaries who are 65 years or older.

The measure estimates a hospital-level 30-day risk-standardized mortality rate (RSMR), defined as death from any cause within 30 days after the index admission date for patients who are between the ages of 50 and 94.

This measure estimates a hospital-level, risk-standardized readmission rate (RSRR) of unplanned, all-cause readmission within 30 days of hospital discharge for any eligible condition. The measure reports a single summary RSRR, derived from the volume-weighted results of five different models, one for each of the following specialty cohorts based on groups of discharge condition categories or procedure categories: surgery/gynecology, general medicine, cardiorespiratory, cardiovascular, and neurology.

Percentage of home health episodes of care during which the patient became less short of breath or dyspneic.

The percentage of home health episodes of care during which the frequency of the patient´s pain when moving around improved.

The percentage of home health episodes of care during which the patient demonstrates an improvement in the condition of surgical wounds.

This measure estimates the mean risk-adjusted mean change in mobility score between admission and discharge for Inpatient Rehabilitation Facility (IRF) Medicare Part A and Medicare Advantage patients.
