Abstract
BACKGROUND AND PURPOSE: The COVID-19 pandemic has impacted the reperfusion therapy for acute ischemic stroke (AIS) patients. Huizhou City utilized its experience with the SARS and MERS breakouts to establish a reperfusion treatment program for AIS patients. METHOD: This is a retrospective study on 8 certified stroke hospitals in Huizhou City from January 2020 to May 2020. We analyzed the number of AIS patients with reperfusion therapy, stroke type (anterior/posterior circulation stroke), modes of transport to hospital, NIHSS score, onset to door time (ODT), door to needle time (DNT), and door to puncture time (DPT). The analysis was compared with baseline data from the same time period in 2019. RESULT: In 2020, the number of AIS patients receiving reperfusion therapy decreased (315 vs. 377), NIHSS score increased [8 (4, 15) vs. 7 [ (1, 2)], P = 0.024], ODT increased [126 (67.5, 210.0) vs. 120.0 (64.0, 179.0), P = 0.032], and DNT decreased [40 (32.5, 55) vs. 48 (36, 59), P = 0.003]. DPT did not change. Seventy percent of AIS patients indicated self-visit as their main mode of transport to the hospital. In both periods, mild stroke patients were more likely to self-visit than utilize emergency systems [2019: 152 (57.6%) vs. 20 (45.6%), P = 0.034; 2020: 123 (56.9%) vs. 5 (14.7%), P < 0.001]. The NIHSS score for self-visiting patients was lower for patients who utilized the ambulance system in both years [self-visit: 6.00 (3.00, 12.00), ambulance: 14.00 (9.00, 19.00), P < 0.001]. The volume of reperfusion patients was lower in 2020; however, the decrease was only significant (P = 0.028) in February 2020. CONCLUSION: During the COVID-19 pandemic in 2020, the number of AIS patients receiving reperfusion therapy significantly decreased when compared to the same period in 2019. The patients' condition increased severity, ODT increased, and the DNT decreased. DPT was not significant for self-visiting and ambulance patients. Moderate to severe stroke patients were more likely to utilize ambulance services.
