- 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 (atypicals)
- 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
Working Ranking
- The following is a reasonable list of commonly-used antibiotics, order from broadest to narrowest, not based on the ASI
- Cefiderocol, Colistin, Polymyxin B, Meropenem-vaborbactam, Imipenem-relebactam, Ceftazidime-avibactam, Ceftolozane-tazobactam, Tigecycline, Meropenem, Doripenem, Ertapenem, Piperacillin-tazobactam, Ticarcillin-clavulanate, Fosfomycin, Moxifloxacin, Levofloxacin, Ciprofloxacin, Doxycycline, Amikacin, Tobramycin, Gentamicin, Cefipime, Ceftazidime, Trimethoprim-sulfamethoxazole, Ampicillin-sulbactam, Amoxicillin-clavulanate, Ceftaroline, Ceftriaxone, Cefuroxime, Cefazolin, Ampicillin, Amoxicillin
