Within Measurement Period Trends
2018 Measure Reporting Year
April 2014 - June 2017
Evaluating trends over time is necessary to identify patterns, changes, and potential unintended consequences in measure results. Users can examine national results for individual years within the current public reporting measurement period. More information on the measurement period can be found in the Notes section below. The visualization can be organized by condition/procedure or by type of measure outcome. Please note that while the graphs present exact data, the sparklines in the default views represent a general shape of changes over time.
To begin exploring the data, please do the following:
Select up to 18 measures (all 18 are selected by default)
Create up to 4 hospital profiles (in addition to the default profile of all hospitals).
Click on the sparklines in the table below to explore percent change from the first year of the three-year measurement period.
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 reporing 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.
