To study factors affecting mechanical thrombectomy (MT) access in a global cohort of countries and estimate the number of MT operators and centers needed country-wise to meet the gap.
MT is a highly effective treatment for large vessel occlusion (LVO) stroke. At a global level, disparities in MT access have not been studied. 

An electronic survey was distributed to 75 MT2020+ Regional Committees. MT access was defined as the proportion of estimated LVO patients receiving MT. Based on an assumption of an optimal MT volume per operator of 50 and an optimal MT volume per center of 150, we defined the following indices: Optimal MT operator index [(One MT operator/Optimal number of LVO) x 100= 1/50 x 100= 2] and optimal MT center index [(One MT center/Optimal number of LVO) x 100 = 1/150 x 100 = 0.67]. The current MT center and operator indices were then calculated for each country as [(Current number of MT operator or center/Optimal number of LVO) x 100].
Complete responses (702) from 59 countries were analyzed. The median MT access was 2.76 % (IQR 0.66 to 14.70). There were significant differences in MT access amongst countries grouped by their per capita gross national income (GNI). On multivariate regression models, MT access correlated with per capita GNI of the country (??: -1.97, 95%, CI -2.70 to -1.24, P <0.001), reimbursement (?? 0.69, CI 0.19 to 1.19, P = 0.008), MT operator index (??: 0.85%, CI 0.30 to 1.39, P = 0.003) and MT center index (??: 2.01, CI - 0.96 to 3.06, P <0.001). China and India have the largest absolute MT center and MT operator gap. 
MT access is low worldwide with vast disparities amongst countries. Determinants of access are the country’s per capita GNI, availability of reimbursement, and their MT operator and center indices.
