Asymptomatic bacteriuria in adolescent girls: II. Screening methods

Area of Science:

• Pediatric Urology
• Infectious Diseases
• Diagnostic Accuracy

Background:

• Asymptomatic bacteriuria in adolescent females is a concern for potential urinary tract infections.
• Accurate and accessible screening methods are crucial for early detection and intervention.
• Understanding patient compliance with home-based testing is vital for public health initiatives.

Purpose of the Study:

• To evaluate the efficacy of three screening methods for bacteriuria in asymptomatic adolescent girls.
• To determine the false-positive rates of dipslide and dipstrip tests.
• To assess factors influencing patient compliance with home nitrite testing, including socioeconomic status.

Main Methods:

• A cohort of 500 asymptomatic adolescent girls was screened using dipslide (Uricult), dipstrip (Microstix), and home nitrite tests.
• Prevalence of bacteriuria was determined, and false-positive rates for dipslide and dipstrip methods were calculated.
• Patient socioeconomic status (Medicaid vs. non-Medicaid) and history of urinary tract infection were analyzed for their impact on home test compliance.

Main Results:

• A prevalence of 1.6% (8/500) for bacteriuria was detected.
• Dipslide and dipstrip tests identified 6/8 cases, while home nitrite tests identified 5/8.
• False-positive rates were 6.4% for dipslide and 2.8% for dipstrip. Non-Medicaid patients showed higher postcard return rates (75.8%) compared to Medicaid patients (63.7%). Prior UTI diagnosis increased compliance.

Conclusions:

• Dipslide and dipstrip tests demonstrate higher sensitivity for detecting bacteriuria in asymptomatic adolescent girls compared to home nitrite tests.
• Home nitrite testing shows potential but is influenced by patient compliance, which is linked to socioeconomic factors and prior UTI experience.
• Further research into optimizing home-based screening strategies is warranted to improve accessibility and adherence across diverse populations.
