NOTE: The Commonwealth Fund has ADDITIONAL rules for ADDITIONAL visualisation/sorting/ranking: see High performers
The instructions below are Pellucid-specific, NOT Commonwealth/WNTB specific. The rules on this page are applied to ALL Pellucid properties.
Summary rule: all process measures are aggregated into composite scores. All composite scores are posted to Pellucid. Web Application Only will decide to suppress scores where d < 30. If a hospital submits ONE data point for one measure, we still produce a composite score. Web Application will suppress it as necessary.
Calculation Method
Composite score in Pellucid is a weighted average of the selected indicator rates, which is the sum of numerators divided by the sum of denominators.
Example: Given 4 fractions, 12/20, 11/30, 10/40 and 9/50, the composite score will be:
∑ numerators / ∑ denominators = (12+11+10+9) / (20+30+40+50) = 42 / 140 = 30%
Components
Composite scores were created for each of the 4 major disease conditions, including AMI, HF, PNE and SCIP. Number of measures increase over time.
Ranking Criteria
For comparability, we take a subset of the composite scores and rank them. Ranking has stricter inclusion than compositing.
...
- Rank 'overal composite' when all 4 topic composite measures were available. i.e. if all four topics meet the criteria, the Overall Composite meets the criteria.
New Footnotes Created for CMS Composite Scores
11 = denominator was less than 30. (Note: this footnote was created when every indicator had less than 30 cases)
...
91 = high performer (i.e. in top 1st percentile.)
This is JMKing's old note:
There are three tiers to the data logic:
