[Hospital-acquired urinary tract infections]

Area of Science:

• Infectious Diseases
• Urology
• Hospital Epidemiology

Background:

• Urinary tract infections (UTIs) constitute 40-60% of hospital-acquired infections.
• Hospitalized patients, particularly the elderly or those with comorbidities, are more vulnerable to HAUTIs.
• Catheter use accounts for approximately 80% of HAUTIs, with invasive procedures causing only 5-10%.

Purpose of the Study:

• To review the challenges and optimal strategies for managing complicated hospital-acquired urinary tract infections.
• To emphasize the importance of pathogen characteristics and host factors in treatment selection.
• To highlight the role of pharmacodynamics and pharmacokinetics in antibiotic choice for HAUTIs.

Main Methods:

• Literature review focusing on hospital-acquired urinary tract infections.
• Analysis of factors influencing susceptibility and treatment success.
• Evaluation of antibiotic properties required for effective UTI management.

Main Results:

• Pathogens causing HAUTIs are frequently multi-resistant.
• Successful antibiotic therapy depends on addressing complicating factors and restoring urodynamic function.
• Antibiotics must possess favorable pharmacodynamic and pharmacokinetic profiles, including renal clearance and activity in varying urine pH.

Conclusions:

• Empirical treatment selection for HAUTIs necessitates assessment of infection site, severity, and local pathogen prevalence.
• Initiating therapy with the most cost-effective, narrow-spectrum antibiotic is recommended pending microbiological results.
• Appropriate UTI management reduces complications, antibiotic use, multi-resistant isolate selection, and healthcare costs.
