The dataset includes 73,216 patients discharged with AIS with increasing yearly volume.  The thrombolytic treatment rate increased from 4.3% in 2010 to 7.2%, 8.0%, 8.9%, 8.9%, 8.1%, 11.2%, and 16.1% over subsequent years.  In 2017, a patient was 3.27x more likely and 1.53x more likely to receive thrombolytic than in 2010 and 2016, respectively (both p<0.001).  The rate of thrombectomy increased from 0.8% in 2014 to 6.4% in 2017; a patient was 8.58x more likely to have thrombectomy in 2017 than 2014 and 1.77x more likely in 2017 than 2016.  In comprehensive stroke centers, 41.3% of all AIS patients received some form of recanalization therapy compared with 21.4% in primary stroke centers, 6.3% in stroke enabled hospitals, and 1.4% in stroke bypass hospitals.

In 2010, one out of every 25 patients discharged after AIS received recanalization therapy; in 2017, one out of every 5 patients was treated.  While we cannot determine relative contribution of aspects of the system of care, the trends in recanalization therapy suggest Louisiana has been successful in improving access to time-sensitive care.
