What’s the problem?
• 20–50% of all antibiotics prescribed in U.S. acute
care hospitals are either unnecessary or inappropriate
• Up to 50% of patients in the hospital are on
antibiotics
• Unnecessary exposure leads to:
– Adverse events (i.e. Clostridioides difficile infection,
toxicity)
– Antimicrobial resistance
– Increased health care cost

Why We Need Stewardship
• What is antimicrobial stewardship?
Don’t think
“antibiotic police” Do think
“antibiotic sommeliers”

• Monthly committee meetings– Infection Prevention &
Antimicrobial Stewardship
– Pharmacy & Therapeutics Committee
• Examples of other collaborative efforts– Creating antibiogram &
institutional guideline
– Implementing diagonisticstewardship initiatives
– Issuing formal statements (ex. managing shortages, inappropriate practices)

Action: Examples
1. Guideline implementation
2. IV to PO conversion
3. Pharmacist automatic renal dosing
4. Diagnostic stewardship– Urine Cultures
– C. diff testing
5. Antibiotic allergy stewardship– Penicillin allergy assessment & skin testing
6. Positive Blood culture reporting coupled with rapid multiplex PCR
7. 48-72 hour time out on all antimicrobials
8. Prospective audit of targeted antimicrobials
9. Antimicrobial restriction policy (criteria must be met prior to dispensing select antimicrobials) 19

Action: Implementation
• The Ideal Implementation:
– Consistent (daily or M-F)
– Real Time, not retrospective
– Method of communication is effective and
efficient
• Protocol-driven vs. EMR alert vs. page vs. face-to-face

patterns
• Assess various measures
– Outcome measures
– Measures related to unintended consequences
– Process measures
– Antibiotic use measures

Utility of Antibiograms
• Guides empiric antimicrobial-use guidelines
• Provides the ability to monitor and trend antibiotic resistance over time
• Allows institutions to compare resistance rates between hospital wards (i.e. Intensive care unit vs. General Floor)
• Can be used as a surrogate marker for the effectiveness of antimicrobial stewardship programs

Limitations of Antibiograms
• Only used for empiric antibiotic selection (not used when culture and sensitivity data are known)
• Information is limited to a geographical area (i.e. state, city, hospital, medical unit) and number of isolates collected.
• Cannot correlate clinical outcomes with percent susceptibility.– For example: 90% of Methicillin sensitive Staph
aureus is susceptible to levofloxacin (in northern MI), but this would not be used in practice because resistance can develop after a couple days into therapy.

Stewardship General Principle
• Just because a bacteria is present in a culture
result, does not mean that antibiotics will
improve the patient’s outcome.
• Prior to recommended antibiotics, we must ask
if the benefit of antibiotic use will outweigh
their risks

How do you respond to “What drug
do I use to treat __________?”
1. Is an infection present?
2. If indicated, are appropriate cultures obtained?
3. Do antimicrobials have data to support improved patient outcomes?
4. Is the benefit of antimicrobial use >>> risk?
5. “5 Right’s” of Antimicrobial pharmacotherapy– Indication
– Drug
– Dose
– Frequency
– Duration 48
