Association between hospital volume, processes of care and outcomes after acute ischaemic stroke: a prospective observational study by Yongjun Wang, Maigeng Zhou, Gaifen Liu, Yuesong Pan, Runhua Zhang

“…However, compared with the highest quartile, the patients in the lowest quartile of hospital volume tend to have poor outcome at 1 year (OR=1.29, 95% CI 1.01 to 1.64, p=0.0393). The restricted cubic spline analyses suggested a non-linear relationship between hospital volume and 1-year combined vascular events and poor outcome at 3 months and 1 year.Conclusions We found no significant associations between hospital volume, processes of care at the hospital, and mortality, recurrent stroke, and combined vascular events in patients with ischaemic stroke. …”
