Reducing urinary tract infections in care homes by improving hydration

Synopsis: Chronic low intake of fluids in older populations creates concentrated urine that irritates the bladder lining and promotes bacterial growth, making urinary tract infections one of the leading causes of non-elective emergency hospital admissions. Establishing structured, multi-time-of-day fluid schedules reduced antibiotic-treated UTIs by 58% and UTI-related emergency hospitalizations by 36% (Lean et al., 2019).

Why It Matters: Dehydration is a preventable health issue. Staying hydrated avoids unwanted hospital visits and supports aging in place.

Hydration Status in Older Adults: Current Knowledge and Future Challenges

Synopsis: Age-related physiological changes—including diminished thirst sensation, decreased renal concentration capacity, and reduced total body water mass—heightens dehydration risk in older adults, directly driving increased hospital readmissions and functional decline. Implementing daily hydration routines effectively counteracts these physiological deficits and supports independent living by avoiding complications (Li et al., 2023).

Why It Matters: Scheduling nutrient- and fluid-rich options throughout the day prevents health crises, keeps seniors out of the hospital, and protects their independence at home.

Hydration Strategies in Older Adults

Synopsis: Liquids containing proteins, fats, soluble fiber, and electrolytes (such as milk, yogurt, or seed-based smoothie bases) possess a higher Beverage Hydration Index (BHI) than plain water. These macronutrients delay gastric emptying, allowing the body to absorb fluids and electrolytes gradually rather than flushing them rapidly through the kidneys (Pence et al., 2025).

Why It Matters: Slower fluid release supports sustained fluid retention, which is particularly beneficial for older adults with altered renal concentration capacity.
