An exploratory study was undertaken to assess the prevalence of dehydration in older patients (aged ≥60 years) with and without cognitive impairment (CI) admitted to hospital and to examine associations between dehydration, CI and frailty. Forty-four patients participated and dehydration was assessed within 24 hours of admission and at day 4 or at discharge, whichever occurred first (study exit). Patients’ cognitive function and frailty status were assessed using validated instruments. Twenty-seven (61%) patients had CI and 61% were frail. The prevalence of dehydration at admission was 29% (n=12) and 19% (n=6) at study exit and dehydration status did not differ according to either CI status or frailty status. Within the non-CI group, however, significantly more frail than fit patients were dehydrated at admission (p=0.03). These findings indicate that dehydration is common amongst older hospital patients, and that frailty may increase the risk for dehydration in cognitively intact older patients.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
