چکیده

Background and Purpose—We aimed to determine the frequency of dehydration, risk factors, and associations with outcomes at hospital discharge after stroke. Methods—We linked clinical data from stroke patients in 2 prospective hospital registers with routine blood urea and creatinine results. Dehydration was defined by a blood urea-to-creatinine ratio 80. Results—Of 2591 patients registered, 1606 (62%) were dehydrated at some point during their admission. Independent risk factors for dehydration included older age, female gender, total anterior circulation syndrome, and prescribed diuretics (all P 0.001). Patients with dehydration were significantly more likely be dead or dependent at hospital discharge than those without ( 2 170.5; degrees of freedom 2; P 0.0001). Conclusions—Dehydration is common and associated with poor outcomes. Further work is required to establish if these associations are causal and if preventing or treating dehydration improves outcomes. (Stroke. 2012;43:00-00.)
