BackgroundDespite intravenous thrombolysis (IVT) being used for the treatment of acute ischemic stroke (AIS) for over two decades, its accessibility remains limited in various regions of the world. The Asian region, which experiences the highest age-standardized incidence of AIS, currently lacks comprehensive data on the utilization of IVT.AimsThis study aimed to provide precise estimates of IVT usage for AIS in Asian countries.MethodsA literature search was conducted on PubMed and Google using appropriate search terms. English language, peer reviewed articles published after 2010 were included in the analysis. The pooled proportion was calculated utilizing the DerSimonian and Laird random-effects model. Additionally, a subgroup analysis was conducted, taking into account factors such as the study's country, the economic status of the country, specific Asian regions, publication year (before 2015 and from 2015 onwards), study location, study setting, hospital stroke protocol, and national stroke guidelines.Results67 observational studies with 778,046 patients with AIS were included in the meta-analysis. The overall utilization rate of IVT was found to be 9.1%. High-income countries had a higher rate (11.3%) compared to lower-middle-income (8.1%) and upper-middle-income countries (9%). Central and North Asia had the highest rate (17.5%) and Southeast Asia had the lowest rate (6.8%). Studies conducted after 2015 had a higher thrombolysis rate (11.3%) compared to those before 2015 (1.5%). Presence of hospital stroke protocols (10.7%) and national stroke guidelines (10.1%) were associated with higher thrombolysis rates.ConclusionThe overall utilization rate of IVT for AIS in Asia stood at 9.1%, showcasing noteworthy disparities across countries, regions, and income brackets. To improve thrombolysis rates in the region, addressing prehospital delays, increasing public awareness, and implementing stroke protocols and national guidelines are key strategies.Copyright © 2023 the Author(s).
