Background/objective: Various strategies have been implemented to reduce acute stroke treatment times. Recent studies have shown a significant benefit of acute endovascular therapy. The JFK Comprehensive Stroke Center instituted Code Neurointervention (NI) on May 1, 2014 for the purpose of rapidly assembling the NI team and rapidly providing acute endovascular therapy.
Design/methods: We performed a retrospective analysis of all patients who had Code NI (Code NI group) called from May 1, 2014 to July 30, 2018 and compared them to patients who underwent acute endovascular treatment prior to initiation of the code (pre-Code NI group) between January 2012 and April 30, 2014. The following parameters were compared: door to puncture (DTP) and door to recanalization (DTR) times, as well as preprocedure NIHSS, 24-hour postprocedure NIHSS, and 90-day modified Rankin scores.
Results: There were 67 pre-Code NI patients compared to 193 Code NI patients. Mean and median DTP times for pre-code NI vs Code NI patients were 161 minutes(mins) vs 115mins (p<0.0001, 31.76-58.86) and 153mins vs 112mins (p <0.0001), respectively. Mean and median DTR times were 220 mins vs 167mins (p <0.0001, 37.76-69.97) and 225mins vs 171mins (p <0.0001). Mean pre-procedure NIHSS was 16 for both groups while 24 hours post procedure NIHSS was 10.6 vs 10.8 (p =.078, 1.8-2.38). Mean 90 day mRS was 2.15 vs 1.65 (p=0.036, 0.32-0.96).
Conclusion: Institution of Code NI significantly improved DTP and DTR times as well as mRS at 3-months postprocedure. Rapid assembly of the NI team, rapid availability of imaging and angiography suite, and streamlining of processes, likely contribute to these differences. These lessons and more widespread institution of such codes will further aid in improving acute stroke care for patients.
