Achieving a Door-to-Needle Time of 25 Minutes in Thrombolysis for Acute Ischemic Stroke: A Quality Improvement Project

Background: Providing intravenous thrombolysis with shortdoor-to-needle time is the result of a complex process that requires specific work standards. To expedite care for acute ischemic stroke patients, close collaboration between all participating health care professionals is required. The aim of this project was to reduce in-hospital treatment delay for acute ischemic stroke patients through the introduction of a standard operating procedure and by creating higher and sustained awareness of the importance of intravenous thrombolysis. Methods: This study was set up as a before-versus-after study, divided into a preintervention period, an immediate postintervention period, and a late postintervention period. During the study, a standard operating procedure was implemented that defined the targeted standard of care to be provided to all acute stroke patients. Involved health care professionals received regular feedback to create greater awareness of the importance of this time-driven protocol. Results: The median door-to-needle time decreased significantly, from 60 minutes in the preintervention period to 30 minutes in the immediate postintervention period (P < .001), and compared with the immediate postintervention period it decreased significantly further, to 25 minutes, in the late postintervention period (P < .001). The proportion of patients with a door-to-needle time, 30minutes and, 20 minutes increased significantly across the 3 study periods (P < .001). Conclusions: The door-to-needle time for acute ischemic stroke patients can be reduced through the introduction of a standard operating procedure and by creating higher and sustained awareness of the importance of intravenous thrombolysis among health care professionals involved.
