EVT requires the close coordination of multiple departments and poses unique challenges to care coordination in large hospitals. We present the results of our quality improvement project that aimed to improve our door-to-groin puncture (DTP) times for patients who undergo EVT after direct presentation to our emergency department.</p><p><strong>Methods: </strong>We conducted time-motion studies to understand the full process of an EVT activation and conducted Gemba walks in multiple hospitals. We also reviewed the literature and interviewed stakeholders to create interventions that were implemented over 4 Plan-Do-Study-Act (PDSA) cycles. We retrospectively collected data starting from baseline and during every PDSA cycle. During each cycle, we studied the impact of the interventions, adjusted the interventions, and generated further interventions. A variety of interventions were introduced targeting all aspects of the EVT process. This included parallel processing to reduce waiting time, standardization of protocols and training of staff, behavioral prompts in the form of a stroke clock, and push systems to empower staff to facilitate the forward movement of the patient. A novel role-based communication app to facilitate group communications was also used.</p><p><strong>Results: </strong>Eighty-eight patients spanning across 22 months were analyzed. After the final PDSA cycle, the median DTP time was reduced by 36.5% compared with baseline (130 minutes (interquartile range [IQR] 111-140) to 82.5 minutes (IQR 74.8-100)). There were improvements in all phases of the EVT process with the largest time savings occurring in EVT decision to patient arrival at the angiosuite.
