Methodology · worked example, guidelines & full notes
Clinical takeaway

Factor in local susceptibility data (e.g. China's CHINET).

When to use

Clarify which organisms each class covers and misses. Empiric choice still needs local susceptibility, infection site and institutional protocol.

How it works

Coverage overview per class (Gram-positive/negative, anaerobes, atypicals, MRSA, Pseudomonas) — not a syndrome-specific regimen.

Key points

  • Factor in local susceptibility data (e.g. China's CHINET).
  • Consider infection site and tissue penetration.
  • De-escalate by susceptibility as soon as results allow.
  • This tool is educational, not an individualised prescription.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Drug classFluoroquinolone

→SpectrumFluoroquinolone

  • Ciprofloxacin：Strong Gram-negative (incl. Pseudomonas), weak Gram-positive
  • Respiratory quinolones (levo/moxi)：Add S. pneumoniae/atypicals; moxifloxacin adds anaerobes but not Pseudomonas
Drug classPenicillin G/V

→SpectrumPenicillin G/V

  • Covers：Streptococci, S. pneumoniae (susceptible), N. meningitidis, T. pallidum, oral anaerobes
  • Misses：Penicillinase-producing staphylococci, most Gram-negative Enterobacterales

FAQ

Frequently asked questions

What are the limits and cautions when using Antibiotic Class Spectrum Quick Reference?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Antibiotic Class Spectrum Quick Reference upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Antibiotic Class Spectrum Quick Reference calculated in practice? Can you show a worked example?
Inputs: Drug class Fluoroquinolone → Result: Spectrum Fluoroquinolone（Ciprofloxacin: Strong Gram-negative (incl. Pseudomonas), weak Gram-positive, Respiratory quinolones (levo/moxi): Add S. pneumoniae/atypicals; moxifloxacin adds anaerobes but not Pseudomonas） Inputs: Drug class Penicillin G/V → Result: Spectrum Penicillin G/V（Covers: Streptococci, S. pneumoniae (susceptible), N. meningitidis, T. pallidum, oral anaerobes, Misses: Penicillinase-producing staphylococci, most Gram-negative Enterobacterales）
