Summary
Antibiotic selection now requires evaluating in vitro activity, pharmacokinetics, resistance, and cost, not just antimicrobial spectrum. Formulary committees need clear criteria for optimal antibiotic therapy decisions.
Area of Science:
- Pharmacology
- Infectious Diseases
- Health Economics
Background:
- Historically, antibiotic selection focused on antimicrobial spectrum.
- Increasing availability of agents with similar coverage complicates selection.
- Pharmacy and Therapeutics (P&T) Committees face new evaluation criteria.
Purpose of the Study:
- To provide perspectives on critical factors in antibiotic formulary decisions.
- To address the complexities of modern antibiotic selection.
- To offer recommendations for optimal antibiotic therapy.
Main Methods:
- Review of current antibiotic selection criteria.
- Analysis of in vitro activity, pharmacokinetics, and resistance data.
- Evaluation of cost-effectiveness and dosing schedules.
Main Results:
- Antibiotic selection is multifaceted, extending beyond spectrum.
- Key considerations include in vitro activity, pharmacokinetics, resistance, cost, and dosing.
- P&T Committees require structured approaches for decision-making.
Conclusions:
- Optimal antibiotic therapy necessitates a comprehensive evaluation of multiple factors.
- Clear guidelines are essential for P&T Committees to navigate complex antibiotic choices.
- Focusing on critical features ensures effective and cost-efficient formulary decisions.
