Current practice of antibiotic prophylaxis for catheter procedures

Area of Science:

• Infectious Diseases
• Antimicrobial Stewardship
• Healthcare Quality Improvement

Background:

• Prophylactic antibiotic use during urinary catheterization lacks established guidelines, leading to variable practices.
• Concerns exist regarding the overuse of antibiotics and rising antimicrobial resistance, particularly without proven efficacy for catheter-related infections.
• Urinary catheter procedures (insertion, change, removal) are common, necessitating standardized protocols for antibiotic prophylaxis.

Purpose of the Study:

• To audit current antibiotic prophylaxis practices for urinary catheter procedures within a single healthcare trust.
• To identify variations in the administration of prophylactic antibiotics, including timing and choice of agent.
• To assess the appropriateness of antibiotic prophylaxis in preventing urinary catheter-related infections.

Main Methods:

• Retrospective audit of patient records for urinary catheter procedures.
• Data collection on antibiotic administration (type, dose, timing) relative to the procedure.
• Analysis of current practices against established (though limited) recommendations.

Main Results:

• Antibiotics were administered in 60% of recorded urinary catheter procedures.
• Gentamicin was the most frequently used prophylactic antibiotic.
• Significant variations in the timing of gentamicin administration were observed, with some instances occurring simultaneously with or after the procedure, suggesting suboptimal prophylaxis.

Conclusions:

• Current practices for antibiotic prophylaxis during urinary catheter procedures are inconsistent and often suboptimal.
• The observed variations highlight a critical need for evidence-based guidelines to standardize antibiotic use.
• Implementing standardized protocols can help optimize antibiotic prophylaxis, mitigate overuse, and combat antimicrobial resistance.
