How Do We Determine Agreement
For Quartiles, Quintiles, and Deciles
1. All hospitals are ranked in order of decreasing performance on the selected reference measure.
2. The hospitals are divided into groups based on their ranking.
-
4 groups for quartiles, 5 groups for quintiles, 10 groups for deciles
3. Steps 1 and 2 are repeated for all measures being compared to the reference measure.
-
Within outcomes, the reference measure is compared to all other measures that have the same outcome (for example, AMI mortality compared to all other mortality measures)
-
Across outcomes selection, the reference measure is compared to measures with different outcomes but the same condition (for example, AMI mortality vs. AMI payment)
4. For any combination of two measures, the level of agreement for each hospital on the two measures is determined by the difference in the hospital’s group ranking (quartile, quintile, or decile number) for the two measures.
5. On the scatterplot, the hospitals are displayed in clusters that corresponds to their measure results and group rankings.

Only hospitals with at least 25 qualifying hospitalizations for a given measure are included in the visualization.
Beginning with the 2019 reporting year, the stroke readmission measure was removed from this data visualization because this measure is no longer reported in the Inpatient Quality Reporting Program (IQR). This measure’s results are still available in reporting years prior to 2019.
DEFINITIONS
Table 2. Key Definitions
Term |
Definition |
Within Outcomes |
Comparison of different conditions within a specified outcome (ex. AMI mortality vs. Heart failure mortality) |
Across Outcomes |
Comparison of the same condition (with the same cohort of patients) across different outcomes (ex. AMI mortality vs. AMI payment) |
Quartiles |
Four equal groups into which a population can be divided per the distribution of values |
Quintiles |
Five equal groups into which a population can be divided per the distribution of values |
Reference Measure |
Measure of interest or measure used to compare to all remaining measures with the same outcome |
Scatterplot |
A scatterplot is used to display values for two variables in a set of data. Scatterplots are used to examine how much one variable is affected by another. |
Performance categories |
To categorize hospital performance, hospitals are classified based on their risk-standardized rate and the associated 95% interval estimate as: |
Payment "performance" categories |
To categorize hospital payment results, hospitals are classified based on their risk-standardized payment and the associated 95% interval estimate as: |
