- Measures the spectrum of an antibiotic, with a range from 0 to 14
- One point for activity against each of the following:
- Methicillin-sensitive Staphylococcus aureus (MSSA)
- Methicillin-resistant Staphylococcus aureus (MRSA)
- Enterococcus faecalis
- Vancomycin-resistant Enterococcus faecalis (VRE)
- Escherichia coli or Klebsiella
- AmpC producers (Enterobacter, Serratia, and Citrobacter)
- Extended-spectrum β-lactamase (ESBL) E. coli/Klebsiella
- Pseudomonas aeruginosa
- Penicillin-resistant pneumococcus (PRP)
- Moraxella and Haemophilus influenzae
- Mycoplasma and Chlamydophila
- Anaerobes (in general)
- Bacteriodes fragilis (specifically)
- Multidrug-resistant organisms
- For each patient, the number of points for every antibiotic is added to give a total daily ASI
