Measure Results by Hospital and Geographic Location

Measurement Period: April 2014 - June 2017

Identifying geographic variation in hospital outcomes is important for improving the quality of care nationwide. Identifying geographic differences in relation to measure outcomes and hospital characteristics at the hospital-, state-, and census region-level helps provide context for policy-related decision making.

To begin exploring the data:

  1. Select up to 6 measures (the hospital-wide readmission measure is selected by default)

  2. Select desired hospital characteristics

  3. Select desired map view at the top right of the map; search for areas of interest at the top left 

The map displays average performance by color, with lighter color indicating better performance and darker color indicating worse performance. Average and individual measure performance data are shown when hovering over or clicking areas of the map. In the Region view, performance is ranked from 1 (best) to 4 (worst). In the Sub-region, State, and Hospital views, deciles [ranked groups from 1 (best) to 10 (worst)] are used.

Please note, for data to appear below, you must select at least one region, state, or hospital.

How This Is Calculated

Results at the Hospital Level: 

1. All hospitals are ranked in order of decreasing performance [lowest value (best performance) to highest value (worst performance)] for each measure.

2. The hospitals are divided into 10 equal groups based on their ranking for each measure.

If only one measure is selected, the results at this level will display which of the 10 groups the hospital was assigned to.

If multiple measures are selected, a simple average of the group assignments is calculated as follows:

 

Results at the State Level:

For each measure, all the hospitals within a state are averaged to get state level performance. This is done by taking the hospital performance multiplied by the number of patients seen at that hospital:

Then, a weighted average of all of the hospitals in the state is calculated:

Then for each measure the states are ranked and placed into deciles:

If only one measure is selected, the results at this level will display which of the 10 groups the state was assigned to.

If multiple measures are selected, a simple average of the group assignments is calculated as follows:

 

Results for the Subregion Level:

Similar to the results at the state level, to get results for the subregion level for each measure a weighted average of all of the hospitals in the subregion is calculated. Then for each measure the subregions are ranked and placed into deciles.

 

Results for the Region Level:

To get results for the region level for each measure, a weighted average of all the hospitals in the region is calculated. Then for each measure the regions are ranked 1 through 4. The ranks are averaged if multiple measures are selected.

There are nine census sub-regions: New England, Middle Atlantic, South Atlantic, East North Central, East South Central, West North Central, East North Central, Mountain, and Pacific

Decile

Ten equal groups into which a population can be divided per the distribution of values
