Abstract The current exploratory study (a) assessed the prevalence of dehydration in older adults (age ≤60 years) with and without cognitive impairment (CI) admitted to the hospital; and (b) examined associations between dehydration, CI, and frailty. Forty-four patients participated and dehydration was assessed within 24 hours of admission and at Day 4 or discharge (whichever occurred first). Patients' cognitive function and frailty statuses were assessed using validated instruments. Twenty-seven (61%) patients had CI and 61% were frail. Prevalence of dehydration at admission was 29% (n = 12) and 19% (n = 6) at study exit, and dehydration status did not differ according to CI or frailty status. However, within the non-CI group, significantly more frail than fit patients were dehydrated at admission (p = 0.03). Findings indicate dehydration is common among older hospitalized patients and that frailty may increase the risk for dehydration in cognitively intact older adults.
