Scoring

Scoring is the method(s) applied to data to generate results/score. Most quality measures produce rates. However, other scoring methods include categorical value, count, continuous variable, frequency distribution, non-weighted score/composite/scale, ratio, and weighted score/composite/scales.

Semantic validation

Semantic validation is a method of testing the validity of an electronic clinical quality measure (eCQM) whereby the formal criteria in an eCQM are compared to a manual computation of the measure from the same test database.

Sensitivity

Sensitivity, as a statistical term, refers to the proportion of actual positives that are correctly identified as such. For example, the percentage of people with diabetes who are correctly identified as having diabetes. See Specificity.

Specification

A specification is the measure instructions that address: data elements, data sources, point of data collection, timing and frequency of data collection and reporting, specific instruments to be used (if appropriate), and implementation strategies.

Specificity

Specificity, as a statistical term, refers to the proportion of negatives that are correctly identified (for example, the percentage of healthy people who are correctly identified as not having the condition). Perfect specificity would mean that the measure recognizes all actual negatives. For example, all healthy people will be recognized as healthy. See Sensitivity.

Standard for Trial Use

A Standard for Trial Use (STU) is used to "provide timely compliance with regulatory or other governmental mandate and/or timely response to industry or market demand." An STU, following a suitable period for evaluation and comment, is incorporated into fully balloted and accredited version of the standard. Formerly called Draft Standard for Trial Use (DSTU).

Stratification

Stratification divides a population or resource services into distinct, independent groups of similar data, enabling analysis of the specific subgroups. This type of adjustment can show where disparities exist or where there is a need to expose differences in results.

Structural measure

A structural measure is one that assesses features of a healthcare organization or clinician relevant to its capacity to provide healthcare.
