100 Recent trends in stroke reperfusion in new zealand
IntroductionStroke reperfusion therapy improves patient outcomes. Here we describe recent trends in the stroke reperfusion intervention rates, treatment delays, and complications across New Zealand.MethodAll 20 DHBs enter acute stroke reperfusion treatment information into a compulsory, centralized, Ministry of Health (MoH) approved and funded Stroke Register. The data from 1/1/2018 through 30/9/18 was cleaned and analysed to explore trends in intervention rates, time delays, and complication rates.ResultsIn the nine-month study period there were a total of 544 (320 males, mean (SD) age 70.6 (14.5) years) patients thrombolysed and 193 patients underwent thrombectomy. For the January-June period, for which MoH stroke denominator rates were available, there was a thrombolysis rate of 10.4%. The overall median time (interquartile range, IQR) for onset-to-door was 76 minutes (48–118), door-to-computed tomography (CT) scan was 23 (15–36) minutes and CT-to-needle was 33 (20–51) minutes. The overall median (IQR) time delay from hospital arrival to thrombolysis was 59 (40–85) minutes and onset-to-needle median (IQR) time was 145 (110–196). There were a total of 26 (4.8%) symptomatic intracerebral haemorrhages (sICH) for the nine-month period. This compares with a thrombolysis rate of 9.85% and door-to-needle time median of 64 minutes in 2017.ConclusionThrombolysis rates in New Zealand continue to rise and now surpass the more recent 10% Ministry of Health target. The continued reduction in door-to-needle time is also an indication of continued service improvement resulting in better patient outcome. However, there are still to be opportunities for improvement.
