Performance Measure Definition: Stroke Alert Blood Glucose Test

Description: This is the percentage of Stroke Alert patients who receive a blood glucose level (BGL) assessment by EMS.
Desired Outcome:  All patients identified as meeting Stroke Alert criteria receive a blood glucose test before arrival at the hospital.
Relevance:  A blood glucose assessment is an important component of the patient assessment leading to determination that a patient meets Stroke Alert criteria.
Measure Domain: Clinical Care
Type of Measure:  Process

Operational Specifications
Formula Description:  Count of Stroke Alert patients with blood glucose level recorded in the Vital Signs section of the ATCEMS ePCR system, divided by the count of all Stroke Alert patients [based on ATCEMSS criteria].
The resulting measure is expressed as a percentage.
Unit of Analysis:  Patient contacts
Population:
  • Numerator: Patients identified as Stroke Alerts who have a documented BGL assessment.
  • Denominator:  Patients identified as Stroke Alerts.
Measure Frequency:  Fiscal quarter
Minimum Population/Sample:  None
Performance Standard:  At least 95% of all Stroke Alert patients will have a BGL assessment recorded in the Vital Signs section of the ATCEMS ePCR system each fiscal quarter.
Acceptable Quality Level:  Performance may not fall below 87% for more than two consecutive quarters or any three quarters in a year.
Interval Description:  Not applicable
Reporting Value:  Percent of patient contacts that meet performance criteria
Aggregation:  Temporal aggregations (month, hour of day, etc.) are based on the date/time of earliest recorded call pickup. 
Stratification: None
Limitations:  Patients for whom medics record findings in locations that are not amenable to standardized reporting tools (e.g. recording findings in narrative or comment fields instead of vital signs fields) will present as a false negative.
Related Measures:  
  • CPI 07 - Blood Glucose Test in Stroke: The CPI measure is generally similar to the Stroke Alert measure, but includes all suspected stroke patients. As a result, the patient contact counts for the CPI measure will be larger, and performance results will vary from the Stroke Alert results.
Notes:  This performance indicator is a component of the Stroke Alert Bundle.
