Version 2021A1

Name:Measure Category Assignment
Collected For: All Records, Calculation, Used in calculation of the Joint Commission's aggregate data.
Definition:Calculated measures results for each episode of care (EOC) that is processed through a measure algorithm.

Used to summarize the outcome for an EOC that is processed through a specific measure algorithm.
Question:Not Applicable
Format:
Length:1
Type:Character
Occurs:One Measure Category Assignment per EOC is expected for every measure that a hospital is participating in.
Allowable Values:

B     Category B - Not in Measure Population
For rate-based and continuous variable measures:
EOC record is not a member of a measure's population.

For rate-based-ratio measures:
Does not apply.

D     Category D - In Measure Population
For rate-based measures:
EOC record is a member of the measure's population and there has not been an occurrence of the measure.

For rate-based-ratio measures:
Does not apply.

For continuous variable measures:
EOC record is a member of the measure's population and has sufficient accurate and valid data to compute the measurement.

Note: For measures where Improvement Noted As: Decrease in the rate (a lower score or a fewer number of cases in the numerator) e.g., PC-01, CSTK-05, Measure Category Assignment of “D” means that the intent of the measure was met. For aggregate data, the EOC record will be included in the measure denominator only.

Note: For continuous variable measures, EOC records that have a Measure Category Assignment of “D” will have an associated Measurement Value.

E     Category E - In Numerator Population
For rate-based measures:
EOC record is a member of the measure's population and there has been an occurrence of the measure.

For rate-based-ratio measures:
Event record is a member of the measure's population and there has been an occurrence of the measure.

For continuous variable measures:
Does not apply.

Note: For measures where Improvement Noted As: Decrease in the rate (a lower score or a fewer number of cases in the numerator) e.g., PC-01, CSTK-05, Measure Category Assignment of “E” means that the intent of the measure was NOT met. For aggregate data, the EOC record will be included in both the measure denominator and numerator

U     Category U — Not In Numerator Population

For rate-based-proportion measures:
Does not apply

For rate-based-ratio measures:
Event record is a member of the measure's population; however, it contains a data element whose allowable value excludes it from the numerator.

For continuous variable measures:
Does not apply.

X     Category X — Data Are Missing
For rate-based and continuous variable measures:
Data are missing that is required to calculate the measure. The record will be rejected by the QIO Clinical Warehouse and the Joint Commission's Data Warehouse.

Y     Category Y — UTD Allowable Value Does Not Allow Calculation of The Measure
For rate-based measures:
Does not apply.

For rate-based-ratio measures: Event record contains a Date, Time, or Numeric data element with a value of UTD'.

For continuous variable measures:
EOC record contains a Date, Time, or Numeric data element with a value of UTD'.

Note:
For continuous variable measures, EOC records that have a Measure Category Assignment of “Y” will not have an associated Measurement Value.
