title: Detecting dehydration in older people: useful tests.
abstract: Dehydration is common in older people, leading to longer hospital stays and increased disability and mortality. Health professionals can diagnose water-loss dehydration by taking a blood sample and measuring serum osmolality, but a less-invasive test would be useful. Evidence that tests, clinical signs or questions tested to date are useful when screening for dehydration in older people is limited. This article looks at known risk factors, signs and test for dehydration, and outlines evidence on how useful they have proven to be. Part 2 describes how a care home has used a multicomponent strategy to improve hydration.
