How This Is Calculated
The following hypothetical example demonstrates how the visualization is calculated, using Medicare and Medicaid dual eligibility as the social risk factor:
1. Overall state performance is calculated for the combined dually eligible ("dual") and non-dual population. Per 1000 admissions in the state:
2. Population of dual and non-dual patients is calculated as the percent of each population out of the entire state population.
3. Performance is calculated for the dual and non-dual populations for each state by calculating the difference between the observed outcome and the expected outcome based on the national performance for each state. Per 1000 admissions in the state:
4. The disparity between the dual and non-dual population is calculated as the absolute difference between the dual and non-dual performance.
Notes
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.
Table 1. Social Risk Factors Definitions
|
Social Risk Factor |
Definition |
|---|---|
| Dual Eligibility Status | Patients are in this category if they are a part of Medicare Part A or Medicare Part B as well as Medicaid. |
| Poverty Line | Patients who fit into this category have a family income that is lower than 90 percent of people in the US. |
| Low Education | Patients fit into this category if they have a level of education lower than 90 percent of people in the US. |
| Unemployed | Patients from zip codes where more than 11.5% of the residents aged 16 years or older are in the labor force who are unemployed and actively seeking work. |
| AHRQ SES Index Score | Patients from zip codes with an Agency for Healthcare Research & Quality (AHRQ) socioeconomic status (SES) index score below 31.8. |
