However, to our knowledge, no study had previously focused on older patients admitted to the emergency department (ED). The present study aimed to evaluate the prevalence, risk factors and short\u2010term outcomes of HD among Thai older patients admitted to the ED.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a prospective cross\u2010sectional study at one urban ED in Thailand. Patients aged \u226565\u2009years who were admitted to the ED were enrolled into the study. Data including clinical hydration status, Charlson Comorbidity Index (CCI) score, activities of daily living score, current use of medications, laboratory examination results and serum osmolarity level were collected. HD was defined as a serum osmolarity level of &gt;300\u2009mOsm\/kg. The short\u2010term outcomes were a 30\u2010day ED revisit, hospital readmission and mortality rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, 80 (21.6%) of 370 patients presented with HD. A CCI score of \u22655 was found associated with HD among older patients (adjusted odds ratio: 1.82; 95% confidence interval: 1.03\u20133.21). The ED revisit rates were 18.1% in the dehydrated group and 10.9% in the non\u2010dehydrated group. The hospital readmission rates were 8.3% in the dehydrated group and 10.6% in the non\u2010dehydrated group. Furthermore, the 30\u2010day mortality rates were 6.9% and 5.3% in the dehydrated and non\u2010dehydrated groups, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>One\u2010fifth of older patients admitted to the ED presented with HD. A CCI score of \u22655 was considered a risk factor of HD. Moreover, further studies should focus on the long\u2010term outcomes of HD and risk reduction. <jats:bold>Geriatr Gerontol Int 2021; 21:
