Measure Set: Comprehensive Stroke(CSTK)
Set Measure ID: CSTK-06
Performance Measure Name: Nimodipine Treatment Administered
Description: Subarachnoid hemorrhage (SAH) patients for whom nimodipine treatment was administered within 24 hours of arrival at this hospital
Rationale: Cerebral vasopasm is a serious complication following SAH, occurring in 30% to 70% of patients and accounting for nearly 50% of the deaths in patients surviving to treatment. Constriction of the arterial lumen results in diminished cerebral perfusion distal to the affected artery, which produces a delayed neurological deficit that may progress to cerebral infarction without early management of the ruptured aneurysm. The arterial narrowing that occurs in cerebral vasospasm is typically a transient or temporary event, lasting from a few days up to 3 weeks. Oral nimodipine is a proven and valuable treatment to prevent
or limit the severity of cerebral vasospasm.
Type of Measure: Process
Improvement Noted As: Increase in the rate
Numerator Statement: SAH patients for whom nimodipine treatment was administered within 24 hours of arrival at this hospital.
Included Populations:
As above
Excluded Populations: None
Data Elements:
Denominator Statement: SAH patients
Included Populations:

Data Elements:
Risk Adjustment: No.
Data Collection Approach: Retrospective data sources for required data elements include administrative data and medical records.
Data Accuracy: Variation may exist in the assignment of ICD-10 codes; therefore, coding practices may require evaluation to ensure consistency.
Measure Analysis Suggestions: None
Sampling: Yes. Please refer to the measure set specific sampling requirements and for additional information see the Population and Sampling Specifications section.
Data Reported As: Aggregate rate generated from count data reported as a proportion.
