Which symptom may indicate a urinary tract infection in the elderly?

• A. Fever
• B. Flank pain
• C. Dysuria
• D. Confusion

Answer: (D)

In older adults, urinary tract infections often show up as non-specific neuropsychiatric changes rather than the classic urinary symptoms. Acute confusion or delirium can be the first sign of infection because aging blunts the typical fever response and urinary symptoms may be difficult to notice or report. This makes confusion the most helpful hint among the options for recognizing a UTI in the elderly. Fever may be absent or minimal in older individuals with infections, flank pain points more toward upper urinary tract involvement and isn’t as common in frail elders with a lower UTI, and dysuria can be underreported due to sensory changes or cognitive impairment. So when you see sudden confusion in an elderly patient, it should prompt evaluation for possible infections like a UTI, along with appropriate testing.
