Point-of-Care Saliva Osmolarity Testing for the Screening of Hydration in Older Adults With Hypertension

Abstract

Objectives: Older adults have an elevated risk of dehydration, a state with proven detrimental cognitive and physical effects. Furthermore, the use of diuretics by hypertensive patients further compounds this risk. This prospective study investigated the diagnostic accuracy of point-of-care (POC) salivary osmolarity (SOSM) measurement for the detection of dehydration in hypertensive adults with and without diuretic pharmacotherapy. Design: Prospective diagnostic accuracy study. Setting: Home visits to patients recruited from 4 community health centers in West Sulawesi, Indonesia. Participants: A total of 148 hypertensive older adults (57 men, 91 women). The mean ages of male and female patie..
