Impact of a hospital-based antimicrobial management program on clinical and economic outcomes

Area of Science:

• Infectious Diseases
• Clinical Pharmacy
• Healthcare Management

Background:

• Inappropriate antimicrobial use leads to resistance, increased costs, and treatment failures.
• Effective antimicrobial stewardship programs are crucial for optimizing patient outcomes and resource allocation.
• Controlling the use of restricted antimicrobial agents requires robust management strategies.

Purpose of the Study:

• To compare the effectiveness of an Antimicrobial Management Team (AMT) versus Infectious Diseases (ID) fellows in improving antimicrobial prescribing.
• To evaluate the impact of different stewardship models on recommendation appropriateness, cure rates, treatment failures, and costs.
• To assess antimicrobial stewardship in an academic setting with a restricted formulary.

Main Methods:

• A comparative study involving 180 patients.
• Recommendations from an AMT (clinical pharmacist and ID physician) were compared with those from ID fellows.
• Outcome measures included appropriateness of recommendations, cure rates, treatment failures, and cost of care.

Main Results:

• The AMT achieved significantly higher appropriateness of recommendations (87% vs. 47%; P<.001) and cure rates (64% vs. 42%; P=.007).
• Treatment failures were lower in the AMT group (15% vs. 28%; P=.03).
• Economic outcomes showed no statistically significant differences between the two groups.

Conclusions:

• The Antimicrobial Management Team (AMT) demonstrated superior antimicrobial prescribing compared to ID fellows in an academic setting.
• AMT interventions are effective in improving clinical outcomes related to antimicrobial use.
• Optimized antimicrobial stewardship programs, like the AMT model, are essential for combating antimicrobial resistance and improving patient care.
