Catheter-Associated Urinary Tract Infection in Neurological Intensive Care Units: A Narrative Review

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Neurology

Background:

• Catheter-associated urinary tract infection (CAUTI) is a prevalent healthcare-associated infection (HAI).
• CAUTI is linked to adverse outcomes, including extended hospital stays, particularly in critically ill individuals.
• Neurological intensive care unit (neuro-ICU) patients face a heightened risk of CAUTI compared to those in other ICUs.

Purpose of the Study:

• To review recent literature (last decade) on CAUTI in neuro-critically ill patients.
• To synthesize data on CAUTI incidence, risk factors, and common pathogens in this specific population.
• To evaluate current preventive strategies and treatment modalities for CAUTI in neuro-ICU settings.

Main Methods:

• Systematic literature search of studies published in the last 10 years.
• Inclusion of studies focusing on neuro-critically ill patients with CAUTI.
• Data extraction on incidence, risk factors, pathogens, prevention, and treatment.

Main Results:

• Incidence rates of CAUTI in neuro-ICU patients vary across studies.
• Key risk factors include urinary catheter duration, severity of illness, and neurological condition.
• Common causative pathogens include Gram-negative bacteria, with increasing antimicrobial resistance noted.

Conclusions:

• CAUTI remains a significant concern in neuro-critical care.
• Understanding specific risk factors and pathogens is crucial for targeted prevention.
• Evidence-based strategies are needed to reduce CAUTI burden in this vulnerable patient group.
