DNA PCR versus urine culture to diagnose and treat urinary tract infections

Diagnosis and Treatment of Urinary Tract Infection Using DNA PCR Versus Urine Culture - A Randomized Controlled Trial

Not applicable Interventional University Hospitals Cleveland Medical Center · NCT06808451

This study will test whether a DNA PCR test instead of a standard urine culture gives faster or more useful results for adults who come to clinic with UTI symptoms.

What this trial studies

Adults aged 18 and older who present to a clinic with symptoms of urinary tract infection are randomized to either standard urine culture or a DNA PCR testing pathway. At enrollment participants complete two questionnaires and, if prescribed antibiotics, they are contacted the day after their scheduled antibiotic stop date and asked to complete follow-up questionnaires. The study procedures and follow-up last up to 21 days. Key exclusions include urinary diversion, chronic indwelling catheter, recent antibiotic use, pregnancy, non-English speakers, and patients with commercial insurance.

Who should consider this trial

Good fit: Ideal candidates are English-speaking adults (18+) who present to the University Hospitals clinic with UTI or cystitis symptoms and have Medicare or Medicaid insurance.

Not a fit: Patients with urinary diversions, chronic indwelling catheters, recent antibiotic use, commercial insurance, non-English speakers, or pregnant patients are excluded and would not receive benefit from participation.

Why it matters

Potential benefit: If successful, this approach could provide faster and more accurate identification of the bacteria causing UTIs, allowing timelier and more targeted treatment.

How similar studies have performed: Molecular tests like PCR have shown quicker detection and higher sensitivity than culture in research settings, but they have not yet replaced urine culture as routine care.
