    Introduction:

    The rate of intravenous thrombolysis (IVT) utilization in acute ischemic stroke (AIS) has been increasing, and this has coincided with improved door-to-needle times (DNTs). Smaller hospitals have been observed to utilize IVT less frequently or even not at all. Using a multistate stroke registry, we sought to determine the impact of hospital size on trends in IVT utilization for AIS.

    Methods:

    Utilizing data from the Paul Coverdell National Acute Stroke Program (PCNASP), we studied trends in IVT for AIS patients between 2010 and 2019 based on hospital size. Hospitals were grouped into quartiles based on size. We studied the impact of hospital size on DNTs and overall IVT utilization.

    Results:

    During the study period, there were 530,828 AIS patients (mean age 70.3 ± 0.02 years, 50.4% men) from 540 participating hospitals. We did not identify a significant trend in IVT utilization among hospitals within the first quartile (p = 0.1005), but there were significantly increased trends within the hospitals belonging to the second, third, and fourth quartiles (p < 0.001 for all). All quartiles were observed to have significantly increased trends in DNTs ≤60 min (p < 0.0001), but only hospitals within the second, third, and fourth quartiles experienced significantly increased trends in DNTs ≤45 min (p < 0.0001).

    Conclusion:

    In our registry-based analysis, we observed an increased trend in IVT utilization for AIS among larger hospitals. There was an overall improvement in rates of DNTs ≤60 min, but only larger hospitals were observed to have improved DNTs ≤45 min.
