We use opportunity-based weights to combine the individual QIs, the approach used by CMS in its pay-for-performance program (Premier 2003), as well as several alternative weighting schemes (AHRQ Quality Indicators 2008a,b).

Composite Measures of Health Care Provider Performance: A Description of Approaches
Opportunity-Based Weights
Opportunity-based weights (also called denominator-based weights) are calculated as the number of people eligible for each type of adverse event (ie, the number of opportunities for an adverse event) divided by the sum of the numbers eligible for each type of event (Table ​(Table1),1), resulting in a composite score of 0.400 (Table ​(Table2).2). As Table ​Table22 shows, the composite score can be calculated most directly as the sum of the number of adverse events across types divided by the sum of the number eligible for each type of adverse event. Thus, a 10-person reduction in each type of adverse event has exactly the same impact on the composite measure. Opportunity-based weights result in the same incentive to focus on each type of adverse event. In addition, opportunity-based weights take into account the differences in the types of patients that a provider might care for, to the extent these differences are reflected in the number of people eligible for each measure (eg, the number eligible for diabetes-related measures compared with the number eligible for measures related to breast cancer screening).
