Measure Set: Comprehensive Stroke (CSTK)

Set Measure ID: CSTK-07

Performance Measure Name: Median Time to Revascularization

Description: Median time from hospital arrival to the start of an intra-arterial (IA) thrombolytic (t-PA) infusion or the first pass (i.e., deployment) of a mechanical reperfusion device to extract an arterial occlusive lesion and restore blood flow to brain tissue.

Rationale: Timely recanalization of an occluded intracerebral artery is a strong predictor of improved functional outcome and reduced mortality in patients with an acute ischemic stroke. Trials of IA lytic agents and mechanical revascularization devices have historically required start of treatment as long as 6-8 hours for anterior circulation strokes of the middle cerebral artery with extended times from symptom onset for vertebrobasilar occulusions. At this time, administration of intra-venous (IV) tissue plasminogen activator (t-PA) within three hours of time last known well remains the recommended first-line approach. However, the short therapeutic window and low rates of recanalization with IV thrombolytic (t-PA) therapy has prompted the investigation of alternative approaches via intra-arterial infusion of a thrombolytic drug or mechanical recanalization with a clot retrieval device. Endovascular treatment of acute ischemic stroke with intraarterial (IA) thrombolytic agents or mechanical thrombectomy is a consideration in patients whom IV t-PA fails or considered likely to fail, who are excluded from IV t-PA treatment, and/or who present with large vessel occlusion that can be detected directly with brain imaging (e.g., noncontrast CT, CT angiography, magnetic resonance angiography (MRA) or indirectly by a high National Institutes for Stroke Scale (NIHSS) Score greater than 10.

Since “time is brain”, the overall speed of the revascularization process is an important and appropriate measure. In multicenter clinical trials of catheter-directed therapies, the probability of good outcome as defined by a Modified Rankin Score of 0-2 at 90 days decreased as time to angiographic revascularization increased. It is estimated that for every 30-minute delay in time to revascularization, there is a 10% decrease in the likelihood of a good outcome from endovascular reperfusion therapy.

Type Of Measure: Process

Improvement Noted As: Decrease in the median value

Continuous Variable Statement: Time (in minutes) from hospital arrival to the start of an intra-arterial (IA) thrombolytic (t-PA) infusion or the first pass of a mechanical reperfusion device in patients with acute ischemic stroke who undergo revascularization therapy.
