Continuous variable measures are measures in which the value of each measurement can fall anywhere along a continuous scale (e.g., the time [in minutes] from hospital arrival to administration of thrombolysis).
The following aggregate data elements are required to be entered for continuous variable measures:
Maximum Observation
Name: | Maximum Observation |
Aggregated For: | Continuous variable measures |
Definition: | The measure's largest observed value for those cases represented in the data element Population for the month. The observed value is the Measurement Value that is calculated for each case as it is processed through the algorithm and received a measure category assignment = ‘D’ for the measure or stratum |
Allowable Values: | 0 through 10,000,000 .000 (calculate to 4 decimals and round to 3 decimals where 5 rounds up) |

Definition: | The measure's average observed value for those cases represented in the data element Population for the month. The observed value is the Measurement Value that is calculated for each case as it is processed through the algorithm and received a measure category assignment = ‘D’ for the measure or strata. Mean Observation is the measure’s average Measurement Value for the hospital during the month. This is calculated by: (Sum the Measurement Values for all cases within the hospital) divided by the Population count previously derived (count of those cases which receive a measure category assignment = 'D') for the measure or stratum. where m = the Population count for the measure or stratum |
Allowable Values: | 0 through 10,000,000 .000 (calculate to 4 decimals and round to 3 decimals where 5 rounds up) |

Definition: | The measure's midpoint observed value for those cases represented in the data element Population for the month. The observed value is the Measurement Value that is calculated for each case as it is processed through the algorithm and received a measure category assignment = ‘D’ for the measure or stratum. To determine the Median, sort the case-level cases by their observed values from the highest value to lowest value: |
