What will I find in Data Exploration?

Types of data exploration:

  • Hospital Performance by Geographic Location
    Explore measure results by region, sub-region, state, or hospital. Narrow results by selecting hospital characteristics or searching for a specific geographic location or hospital name.

  • Episode-of-Care Payment
    Examine what percent or how much each care setting contributes to payment for AMI, Heart Failure, and Pneumonia. Care settings include both hospital admission and post-acute care.

  • National Rates over Time
    Examine national trends in AMI, COPD, Heart Failure, and Pneumonia admission, readmission, and observation stay rates. Adjust the timeframe from January 2006 through two months ago.

  • Customize and Compare Hospital Peer Groups
    Select hospital characteristics or search for a specific hospital to build a hospital profile. Then compare measure results for each hospital profile.

  • Hospital Measure Results Agreement
    Examine how consistently hospitals perform on pairs of outcome measures.

  • Overlap in Social Risk Factors
    Select one or more sociodemographic characteristics to explore how many hospitals meet the selected characteristics and their geographic location, for each measure.

  • Within Measurement Period Trends​
    Evaluate measure trends across three years to identify patterns, changes, and potential unintended consequences in measure results.

  • State Level Disparities​
    Explore how a state's overall performance on CMS's hospital quality measures relates to their performance for patients with social risk factors.



Data Visualization Navigation and Calculations

Instructions for using each visualization and how each visualization is calculated can be found at the bottom of each of the visualizations. 

What will I find in Research Briefs?

Each of the measures have the following analytic briefs:

  • Hospital Variation
    The distribution of hospital results (risk standardized mortality rate, risk standardized readmission rate, or risk standardized payment) for each measure.

  • Three-Year Trends in Condition-Specific Rates
    Trends analysis of the median hospital results for three reporting years.

  • Results by Social Risk Factor: Medicaid Patients
    The performance of hospitals in the deciles with the highest and lowest proportion of Medicaid patients.

  • Results by Social Risk Factor: African-American Patients
    The performance of hospitals in the deciles with the highest and lowest proportion of African-American patients.

  • Results by Hospital Characteristics
    The performance of hospitals based on safety-net status, teaching status and urban/rural location.

Each of the payment measures also include:

  • Index versus Post-Acute Care Payments
    The distribution of risk standardized payment for index hospitalizations and post-acute care, defined by quintile.
