UTIs In The Elderly

Diagnosing urinary tract infections (UTIs) in older adults requires distinguishing between symptomatic infections and asymptomatic bacteriuria, which is highly prevalent in this population. Over-treating colonization with antibiotics contributes to multidrug-resistant pathogens and adverse drug reactions, while under-treating can lead to sepsis. Emergency departments frequently initiate unnecessary indwelling urinary catheters, significantly increasing the risk of catheter-associated urinary tract infections (CAUTIs). Implementing standardized protocols that mandate clinical justification for catheter placement, promote alternative collection methods, and require regular reassessment for removal can drastically reduce these complications. Geriatric emergency medicine expert Mary Mulcare emphasizes that while urine cultures remain the diagnostic gold standard, clinicians must prioritize evidence-based stewardship to avoid the pitfalls of reflexive testing and catheterization, ultimately improving patient outcomes and reducing hospital-acquired conditions.
