Measure Description

Percentage of patients aged 18 years and older with a diagnosis of acute ischemic stroke who arrive at the hospital within two hours of time last known well and for whom IV t-PA was initiated within three hours of time last known well

 

Instructions

This measure is to be submitted for each episode of acute ischemic stroke for patients who arrive at the hospital within two hours of time last known well and for whom IV t-PA was initiated within three hours of time last known well. It is anticipated that Merit-based Incentive Payment System (MIPS) eligible clinicians providing care for patients with acute ischemic stroke in the hospital setting will submit this measure.

Measure Submission Type:

Measure data may be submitted by individual MIPS eligible clinicians, groups, or third party intermediaries. The listed denominator criteria are used to identify the intended patient population. The numerator options included in this specification are used to submit the quality actions as allowed by the measure. The quality-data codes listed do not need to be submitted by MIPS eligible clinicians, groups, or third party intermediaries that utilize this modality for submissions; however, these codes may be submitted for those third party intermediaries that utilize Medicare Part B claims data. For more information regarding Application Programming Interface (API), please refer to the Quality Payment Program (QPP) website.

AND

Time last known well to arrival in the emergency department less than or equal to two hours (≤ 120 minutes)

 

Numerator

Patients for whom IV thrombolytic therapy was initiated at the hospital within three hours (≤ 180 minutes) of time last known well

Definition:

Last Known Well – The date and time prior to hospital arrival at which it was witnessed or reported that the patient was last known to be without the signs and symptoms of the current stroke or at his or her baseline state of health.

Numerator Options:

Performance Met: IV t-PA initiated within three hours (≤ 180 minutes) of time last known well (G8600)

OR

Denominator Exception: IV t-PA not initiated within three hours (≤ 180 minutes) of time last known well for reasons documented by clinician (eg, patient enrolled in clinical trial for stroke, patient admitted for elective carotid intervention) (G8601)

OR

Performance Not Met: IV t-PA not initiated within three hours (≤ 180 minutes) of time last known well, reason not given (G8602)

 

Rationale

The administration of thrombolytic agents to carefully screened, eligible patients with acute ischemic stroke has been shown to be beneficial in several clinical trials. These included two positive randomized controlled trials in the United States; The National Institute of Neurological Disorders and Stroke (NINDS) Studies, Part I and Part II. Based on the results of these studies, the Food and Drug Administration approved the use of intravenous recombinant tissue plasminogen activator (alteplase) for the treatment of acute ischemic stroke when given within 3 hours of stroke symptom onset. A large meta-analysis controlling for factors associated with stroke outcome confirmed the benefit of IV alteplase in patients treated within 3 hours of symptom onset. While controversy still exists among some specialists, the major society practice guidelines developed in the United States all recommend the use of IV alteplase for eligible patients. Physicians with experience and skill in stroke management and the interpretation of CT scans should supervise treatment.

 

Clinical Recommendation Statements

IV alteplase (0.9 mg/kg, maximum dose 90 mg over 60 minutes with initial 10% of dose given as bolus over 1 minute) is recommended for selected patients who may be treated within 3 hours of ischemic stroke symptom onset or patient last known well or at baseline state.
