| *<p> | ||
| * <ul> | ||
| * <li>'not-applicable': When a subject does not meet the criteria for the Measure scenario, whether by exclusion or exception criteria, or just by not meeting any required criteria, they will not show membership results in the 'Denominator'.</li> | ||
| * <li> subject is applicable (not a status): When a subject meets the criteria for a Measure they will have membership results in the 'Denominator', indicating they are of the appropriate criteria for the Measure scenario.</li> | ||
| * If in membership of 'Denominator', the subject will be assigned a 'closed-gap' or 'open-gap' status based on membership in 'Numerator' and the 'improvement notation'. | ||
| *</ul> | ||
| * </p> | ||
| * <p> | ||
| * Improvement Notation of Scoring Algorithm indicates whether the ratio of Numerator over Denominator populations represents a scenario to increase the Numerator to improve outcomes, or to decrease the Numerator count. If this value is not set on a Measure resource, then it is defaulted to 'Increase' under the IsPositive variable. | ||
| * </p> | ||
| * <ul> | ||
| * <li>ex: 1/10 with improvementNotation "decrease" means that the measureScore is 90%, therefore absense from 'Numerator' means criteria for care was met</li> | ||
| * <li>ex: 1/10 with improvementNotation "increase" means that the measureScore is 10%, therefore absense from 'Numerator' means criteria for care was NOT met.</li> | ||
| * </ul> | ||
| * <ul> | ||
| * <li>'open-gap': if in 'Denominator' & NOT in 'Numerator', where 'improvement notation' = increase. Then the subject is 'open-gap'</li> | ||
| * <li>'open-gap': if in 'Denominator' & in 'Numerator', where 'improvement notation' = decrease. Then the subject is 'open-gap'</li> | ||
