- Higher prevalence of new or worsening confusion in nursing home (NH) residents drove significantly higher urinary tract infection (UTI) antibiotic use within past month (P<.001).
- No differences were observed in documented UTI or symptomatology in this patient population vs individuals residing in nontropical environment.
Why this matters
- Asymptomatic bacteriuria in NH residents may accompany an array of nonspecific symptoms, leading to overprescribing of antibiotics without established UTI diagnosis.
- A high prevalence of confusion in NH residents should not be the primary driver of a clinical strategy; prudent use of narrow- vs broad-spectrum agents is recommended.
- 450 NH residents were included; 3% (n=13) had a documented current UTI and 9% (n=40) had a UTI within the last 30 days.
- UTI accounted for 33% of current infections and 40% of all infections within the last 30 days.
- Over the course of 30 days, 20% NH residents had received antibiotics (45% for suspected UTI).
- Factors significantly associated with UTI antibiotics ≤30 days included catheterization (OR, 13; 95% CI, 2.4-67; P=.003).
- Cross-sectional, observational study quantifying prevalence of documented UTI, nonspecific symptoms, and antibiotic treatment in Australian NH residents.
