Strategic alliance between the infectious diseases specialist and intensive care unit physician for change in antibiotic use

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Antimicrobial Stewardship

Background:

• Antimicrobial use is notably higher in intensive care units (ICUs) compared to general hospital wards.
• Optimizing antibiotic prescribing in ICUs is crucial for combating antimicrobial resistance and managing healthcare costs.

Purpose of the Study:

• To evaluate the impact of systematic infectious disease (ID) consultations on antibiotic prescribing patterns in an ICU.
• To assess the effect of this intervention on patient outcomes, including length of hospital stay and mortality.

Main Methods:

• A collaborative strategy was implemented, involving infectious disease consultants and ICU leadership.
• Antibiotic prescription habits of ICU physicians were systematically reviewed and modified.
• The study tracked the utilization of specific broad-spectrum antibiotics, including third-generation cephalosporins, vancomycin, carbapenems, and piperacillin-tazobactam.

Main Results:

• A significant reduction in the use of targeted antibiotics was observed following the intervention.
• The length of hospital stay for ICU patients was significantly decreased.
• Healthcare costs associated with antibiotic use were lowered.
• No adverse impact on patient mortality was detected.

Conclusions:

• Systematic infectious disease consultations, supported by ICU physician commitment, effectively modify antibiotic prescribing habits.
• This approach represents a simple and effective method for antimicrobial stewardship in the intensive care setting.
• The strategy successfully reduced antibiotic consumption and improved resource utilization without compromising patient safety.
