Objective: Intravenous thrombolysis within 4.5 hours from time of onset has proven benefit in stroke. Universal standard for the door-to-needle (DTN) time is within 60 minutes from the time of arrival of patients to the emergency department. Our rapid thrombolysis protocol (RTPr) was developed with an aim to reduce the DTN time to a minimum by modifying our stroke post-intervention processes.
Methods: This before-and-after study was conducted at a single center on patients who received intravenous thrombolysis in the emergency department. Consecutive patients who were thrombolysed using our RTPr (post-intervention group) were compared to the pre-intervention group who were thrombolysed before the implementation of the protocol. The primary outcomes were DTN time, time to recovery, and modified ranking score (mRS) on discharge. Secondary outcomes were mortality, symptomatic intracerebral hemorrhage, and hospital and intensive care unit length of stay.
Results: Seventy-four patients were enrolled in each group. Mean DTN time in pre- and post-intervention group was 56.15 minutes (95% CI 49.98–62.31) and 34.91 minutes (95% CI 29.64–40.17) (p <0.001), respectively. In pre-intervention and post-intervention groups, 43.24% (95% CI 32.57–54.59) and 41.89% (95% CI 31.32–53.26) patients, respectively, showed neurological recovery in 24 hours. About 36.49% (95% CI 26.44–47.87) in pre-intervention group and 54.05% (95% CI 42.78–64.93) in post-intervention group had discharge mRS 0–2.
Conclusion: The RTPr can be adapted by clinicians and hospitals to bring down the DTN times and improve outcomes for stroke patients.
