The NQF validity criterion tests whether measure specifications are consistent with the measure intent and captures the most inclusive target population. There are two main types of validity, measure validity and data element validity. Measure validity is when the measure accurately represents the concept being evaluated and achieves the purpose for which it is intended (to measure quality). Data element validity is the extent to which the information represented by the data element or code. See measure validity and data element validity.
A value set is a list of specific values, terms, and their codes, used to describe clinical and administrative concepts in the quality measures. Value sets provide groupings of unique values along with a standard description or definition from one or more standard vocabularies used to describe the same clinical concept, e.g., diabetes, clinical visit, demographics, within quality measures.
The Virtual Medical Record (vMR) is a data model for representing the data that are analyzed and/or produced by clinical decision support (CDS) engines.
