The influence of the prevalence of covid-19 on intravenous thrombolytic therapy in patients with acute ischemic stroke in Dalian / 中国医师进修杂志

ABSTRACT

Objective:To investigate the influence of Covid-19 epidemic on the number of acute ischemic stroke patients with intravenous thrombolytic therapy in Dalian in 2020, the way to hospital, onset to door time (ODT), door to needle time(DNT), onset to needle time(ONT), and the National Institute of Health Stroke Scale (NIHSS) before and after intravenous thrombolytic therapy.Methods:This was a retrospective descriptive study on 13 map-participating hospitals in Dalian from August 2020 to December 2020. The number of acute ischemic stroke patients with intravenous thrombolytic therapy, ODT, DNT, ONT, modes of transport to hospital, the NIHSS score before and after intravenous thrombolytic therapy, etc were analyzed. Data were collected from August 1, 2020 to December 31, 2020, and compared with the baseline data from the same period in 2019.Results:SPSS 22.0 statistical software and Data Analysis ToolPak were used for statistical analysis of the obtained data, and T tests statistic was used for data analysis. In 2020,the number of acute ischemic stroke patients with intravenous thrombolytic therapy increased (681 cases vs 416 cases), and DNT increased [50 minutes vs 45 minutes P = 0.01]. In 2020, 83.55% of patients indicated self-visit as their main mode of transport to the hospital. In 2020, among the self-visit patients with NIHSS score<15 scores,the number of the patients with the NHISS score unchanged or decreased after intravenous thrombolytic therapy was more (562 scores vs. 535 scores, P<0.001), and the patients with NIHSS score ≥15 scores were more willing to call ambulances to hospital. Conclusions:During the Covid-19 epidemic period of 2020, the number of acute ischemic stroke patients receiving intravenous thrombolytic therapy increased, DNT increase; the patients withNIHSS score<15 scores are more willing to choose to visit the hospital using their own transportation and benefit from intravenous thrombolytic therapy. The patients with NIHSS ≥15 scores prefer to call ambulances to hospital.
