Access to acute stroke unit (ASU) care is known to vary worldwide. We aimed to quantify regional variations in the various components of ASU care.
Secondary analysis of the Head Positioning in acute Stroke Trial (HeadPoST), an international, multicentre, cluster crossover trial of head-up versus head-down positioning in 11,093 acute stroke patients at 114 hospitals in 9 countries. Patients characteristics and 11 standard components of processes of care were described according to ASU admission within and across four economically-defined regional groups (Australia/UK, China [includes Taiwan], India/Sri Lanka, and South America [Brazil/Chile/Colombia]). Variations in process of ASU care estimates were obtained in hierarchical mixed models, with adjustment for study design and potential patient- and hospital-level confounders.
Of 11,086 patients included in analyses, 59.7% (n = 6620) had an ASU admission. In China, India/Sri Lanka and South America, ASU patients were older, had greater neurological severity and more premorbid conditions than non-ASU patients. ASU patients were more likely to receive reperfusion therapy and multidisciplinary care within regions, but the components of care varied across regions. With Australia/UK as reference, patients in other regions had a lower probability of receiving reperfusion therapy, especially in India/Sri Lanka (adjusted odds ratio [aOR] 0.27, 95% confidence interval [CI] 0.12-0.63) and multidisciplinary care (mainly in formal dysphagia assessment, physiotherapy and occupational therapy).
There is significant variation in the components of stroke care across economically-defined regions of the world. Ongoing efforts are required to reduce disparities and optimise health outcomes, especially in resource poor areas.
HeadPoST is registered at ClinicalTrials.gov (NCT02162017).
