IDID Regimen Engine

Pharmacist.Guide / antimicrobial decision engine

Patient data in. Treatment plan out.

Built like a RapidPEP-style clinical engine for infectious disease: structured variables, prior cultures, resistance memory, and a visible reasoning trail.

Treatment Plan

PneumoniaStewardship review recommended

Primary empiric frame

Standard pneumonia pathway: respiratory syndrome classification, severity, MRSA/Pseudomonas risk, and culture quality.

Initial coverage direction

Use an inpatient pneumonia backbone. Add MRSA or antipseudomonal coverage only when severity, prior isolates, local risk, or validated screening supports it.

MRSA memory

Prior MRSA signal detected. Decide whether it matches the current syndrome before adding or continuing MRSA-active coverage.

Diagnostics

  • Assess CAP/HAP/VAP context
  • Obtain quality respiratory culture when severe or resistant risk exists
  • Review MRSA nares and prior respiratory isolates

Safety / Dosing

  • Renal function entered: CrCl 54 mL/min. Dose-adjust where required.
  • Weight entered: 82 kg. Check weight-based dosing when applicable.
  • No beta-lactam allergy entered.

Warnings

  • Source control is not confirmed. Regimen selection alone is insufficient.

De-escalation instruction

Confirm oxygen trajectory, imaging pattern, aspiration context, and need for ICU-level coverage. Short course once clinically stable, adjusted by pathogen, complications, and response.
