{[{vizh.year}]} Measure Reporting Year

How This Is Calculated
To calculate three-year trends, we examined the national measure results for each year of the three-year public reporting measurement periods. The dates for each year of data collection in the public reporting measurement period are listed in the notes section below. We allow users to view the results by hospital characteristic profiles with 5 or more hospitals.
-
For each year of the three-year measurement period, all hospitals are ranked in order of performance and the median is determined.
-
The graphs use units of percent change, with the first year of the performance period fixed at zero and subsequent years located relative to the first. The following formula is used to calculate percent change:
-
For each year of the three-year measurement period, the 25th and 75th percentiles determine the interquartile ranges for the results.

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.
