Antimicrobials and therapeutic decision making: an historical perspective

Area of Science:

• Hospital Administration
• Infectious Disease Management
• Clinical Pharmacy

Background:

• Inappropriate and excessive antimicrobial use necessitates cost control and improved patient outcomes.
• Antimicrobial stewardship programs (ASPs) are widely adopted by hospitals to address these challenges.

Purpose of the Study:

• To describe effective antimicrobial stewardship strategies implemented at Hartford Hospital.
• To highlight approaches that minimize physician error, reduce ancillary service burden, and shorten hospital stays.

Main Methods:

• Automated correction of antimicrobial dosage and intervals.
• Pharmacy-led conversion to cost-effective alternative agents.
• Daily multidisciplinary antimicrobial team review of patients.
• Early transition from parenteral to oral antimicrobial therapy.

Main Results:

• Strategies focus on system-level improvements rather than solely relying on physician behavior change.
• Implementation requires adaptation of traditional prescribing habits and pharmacist involvement.

Conclusions:

• Effective antimicrobial stewardship programs integrate automated interventions, clinical review, and early therapeutic switching.
• Physician acceptance and pharmacist collaboration are crucial for successful implementation and cost control.
