The eligible patients were identified according to inclusion/exclusion criteria. In total, 2570 acute ischaemic and 573 acute hemorrhagic stroke patients were finally recruited. According to the blood urea nitrogen (BUN) to creatinine (Cr) ratio (BUN/Cr), these patients were divided into dehydrated (BUN/Cr ≥ 15) and non‐dehydrated (BUN/Cr < 15) groups. Demographics, admission costs and discharge outcomes including modified Rankin scale (mRS) and Barthel index (BI) were examined. Data were analyzed using multivariate analysis of two‐stage least squares including logistic and linear regression.</p> </sec> <sec id="ene12452-sec-0003" sec-type="section"> <title>Results</title> <p>Acute ischaemic stroke with admission dehydration had higher infection rates (<italic>P </italic>=<italic> </italic>0.006), worse discharge BI (62.8 ± 37.4 vs. 73.4 ± 32.4, <italic>P </italic><<italic> </italic>0.001, adjusted <italic>P </italic><<italic> </italic>0.001), worse mRS (2.7 ± 1.6 vs. 2.3 ± 1.5, <italic>P </italic><<italic> </italic>0.001, adjusted <italic>P </italic>=<italic> </italic>0.009) and higher admission costs (2470.8 ± 3160.8 vs. 1901.2 ± 2046.8 US dollars, <italic>P </italic><<italic> </italic>0.001, adjusted <italic>P </italic>=<italic> </italic>0.013) than those without dehydration.
