AHA: 11/8/12

Background and Purpose—Earlier tissue-type plasminogen activator (tPA) treatment for acute ischemic stroke increases efficacy, prompting national efforts to reduce door-to-needle times. We used lean process improvement methodology to develop a streamlined intravenous tPA protocol.

Methods—In early 2011, a multidisciplinary team analyzed the steps required to treat patients with acute ischemic stroke with intravenous tPA using value stream analysis (VSA). We directly compared the tPA-treated patients in the “pre-VSA” epoch with the “post-VSA” epoch with regard to baseline characteristics, protocol metrics, and clinical outcomes. Read more
