“Dehydration is a complicating condition that increases the likelihood of hospitalization of many common diseases of older adults, including congestive heart failure, cancer treatments, and diabetes. By detecting dehydration early, we have the potential to reduce costly hospitalizations and improve the quality of life for older adults.”

In her research at UCLA, Janet C. Mentes has worked to improve the care of older adults, primarily in oral hydration, oral care, and delirium detection and management. Her current research focuses on early detection and management of dehydration in community and institutional settings. Dr. Mentes has demonstrated that urine color and saliva analysis can be effectively and easily employed in nursing homes. Three products have resulted from her research: a Hydration Management Protocol (available from the University of Iowa), a urine color chart for evaluating hydration status in nursing home residents, as well as a systematic classification of hydration problems for those residents. Dr. Mentes is the co-director of the Center for Advancement of Gerontological Nursing Research (AGNS) and a Director at Large of the National Hartford Center of Gerontological Nursing Excellence. She evaluates a mentorship program aimed at increasing the number of nurses with PhDs from diverse backgrounds, to decrease health disparities among the underrepresented minority groups.

Faculty Research and Clinical Expertise

Research: Improving the care of older adults, primarily in areas of oral hydration, oral care, and delirium detection and management. Current research emphasis is on early detection and management of dehydration in older adults in community and institutional settings, through the use of various biomarkers, such as urine and salivary parameters along with hydration habits.

Clinical: Gerontological and psychiatric nursing

I have developed the following products from my research: Hydration Management Protocol (Available from the University of Iowa)  Validated a urine color chart for evaluating hydration status in nursing home residents  A typology of hydration problems in nursing home residents
