Antibiotic Stewardship in the Emergency Department

Core Strategies for ED Antibiotic Stewardship

  • The American College of Emergency Physicians recommends biomarker testing and rapid pathogen testing to improve antibiotic prescribing decisions for patients presenting with infectious syndromes 3, 4
  • Blood cultures should be obtained selectively in patients with community-acquired pneumonia, urinary tract infections, or skin/soft tissue infections, particularly when signs of sepsis are absent 4
  • Rapid diagnostic testing helps distinguish between viral and bacterial pathogens, reducing unnecessary antibiotic use and enabling appropriate narrow-spectrum therapy when indicated 5
  • Watchful waiting or delayed antibiotic prescribing should be considered for select patients with lower respiratory tract infections, acute COPD exacerbations, uncomplicated cystitis, or diverticulitis 4, 6
  • Structured culture follow-up programs should be implemented for patients discharged from the ED with pending cultures to ensure appropriate antibiotic therapy adjustments 4, 6
  • Shortening duration of therapy according to current guidelines reduces selective pressure for resistant bacteria without compromising outcomes 5
  • Dose optimization based on patient characteristics, pathogen, infection site, and pharmacokinetic/pharmacodynamic properties improves efficacy and reduces resistance 5

Organizational Approaches

  • ED clinician representation on hospital antimicrobial stewardship committees is essential for successful implementation 7
  • Collaboration between ED clinicians, pharmacists, microbiologists, and infectious disease specialists yields the most effective stewardship programs 7
  • A dedicated pharmacist as part of the ED team plays a critical role in addressing appropriate antibiotic use 8
  • Active educational programs including seminars and roundtable discussions promote dialogue and clinician engagement 7
  • Educational messaging should be tailored to ED-specific practice patterns and challenges 7
  • Inclusion of infectious disease topics in departmental grand rounds and inter-specialty conferences facilitates improved antibiotic use 7
  • Process and outcome measures should track antimicrobial utilization and resistance patterns 7
  • Post-prescription review with patient follow-up ensures appropriate transitions to outpatient care 5
  • Monitoring appropriateness of antibiotic therapy choice, rehospitalization rates, and time to culture review helps evaluate program effectiveness 6

Implementation Considerations

  • Adapt implementation strategies to the specific settings and circumstances of individual EDs 2
  • Acknowledge the tension between appropriate broad-spectrum antibiotic use for life-threatening infections and antimicrobial stewardship goals 7
  • Failure to address barriers to implementation can hinder uptake of recommended practices, and understanding these barriers is crucial for successful implementation 1, 9
