Set Measure ID	Performance Measure Name
CSTK-03a	Hunt and Hess Scale Performed for SAH Patients
CSTK-03b	ICH Score Performed for ICH Patients

Performance Measure Name: Severity Measurement Performed for SAH and ICH Patients (Overall Rate)

Description: Subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH) stroke patients for whom a severity measurement (i.e., Hunt and Hess Scale for SAH patients or ICH Score for ICH patients) is performed prior to surgical intervention (e.g. clipping, coiling, or any surgical intervention) in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of arrival at the hospital emergency department for patients who do not undergo surgical intervention.

CSTK-03 SAH and ICH stroke patients for whom a severity measurement is performed prior to surgical intervention in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of hospital arrival for patients who do not undergo surgical intervention.

CSTK-03a SAH stroke patients for whom a severity measurement is performed prior to surgical intervention in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of hospital arrival for patients who do not undergo surgical intervention.

CSTK-03b ICH stroke patients for whom a severity measurement is performed prior to surgical intervention in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of hospital arrival for patients who do not undergo surgical intervention.

The CSTK-03 measure is reported as an overall rate which includes SAH and ICH stroke patients for whom a severity measurement is performed prior to surgical intervention in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of hospital arrival for patients who do not undergo surgical intervention; CSTK-03a and CSTK-03b are subsets of the overall rate, and stratified by the type of stroke patient.

Rationale: Subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH) are medical emergencies requiring rapid diagnosis and assessment. Early deterioration is common in the first few hours after onset, and associated with increased mortality rates of > 75% compared to 30-day mortality rates of 35%-52%. More than half of all deaths from these conditions occur within the first two days. According to the American Heart Association/American Stroke Association, the severity of SAHs should be documented with the Hunt and Hess Scale, and the severity of ICHs should be documented with ICH score to capture the clinical state of the patient. The severity of initial neurological injury should be determined and documented in the emergency department because it is a useful predictor of outcome and helpful in planning future care with family and physicians. For both severity methodologies, higher scores are associated with increased mortality.

Type Of Measure: Process

Improvement Noted As: Increase in the rate

Numerator Statement:
CSTK-03: The number of SAH and ICH stroke patients for whom a severity measurement is performed prior to surgical intervention in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of hospital arrival for patients who do not undergo surgical intervention.

CSTK-03a: The number of SAH patients for whom a Hunt and Hess Scale is performed prior to surgical intervention in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of hospital arrival for patients who do not undergo surgical intervention.

CSTK-03b: The number of ICH stroke patients for whom an ICH Score is performed prior to surgical intervention in patients undergoing surgical intervention and documented in the medical record; OR documented within 6 hours of hospital arrival for patients who do not undergo surgical intervention.

Denominator Statement: SAH and ICH stroke patients

Included Populations: Discharges with ICD-10-CM Principal Diagnosis Code for hemorrhagic stroke as defined in Appendix A, Table 8.2 for ICD-10 codes (i.e., Table 8.2a and Table 8.2b) with or without aneurysm repair procedure (ICD-10-PCS Principal or Other Procedure Code as defined in Appendix A, Table 8.2d for ICD-10 codes) or surgical intervention procedure (ICD-10-PCS Principal or Other Procedure Code as defined in Appendix A, Table 8.2e for ICD-10 codes)
Excluded Populations:

Patients less than 18 years of age

Patients who have a Length of Stay > 120 days

Patients with Comfort Measures Only documented on the day of or day after hospital arrival

Non-surgical patients discharged within 6 hours of arrival at this hospital

Patients with traumatic brain injury (TBI), unruptured arteriovenous malformation (AVM), and non-traumatic subdural hematoma (ICD-10-CM Other Diagnosis Codes as defined in Appendix A, Table 8.2f for ICD-10 codes)

Patients who have an ICD-10-CM Principal Diagnosis Code in Appendix A, Table 8.2a assigned at discharge and documentation of non-aneurysmal SAH or SAH related to head trauma any time during the hospital stay

Data Elements:

Admission Date

Birthdate

Comfort Measures Only

Discharge Date

Discharge Time

ICD-10-CM Other Diagnosis Codes

ICD-10-CM Principal Diagnosis Code

ICD-10-PCS Other Procedure Codes

ICD-10-PCS Principal Procedure Code

Non-aneurysmal

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: Hospitals may wish to identify those patients that did not receive a severity assessment within the specified timeframe(s), or received a severity assessment that did not match their diagnosis, or both, so that efforts can be directed toward improving care.

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.
