Guidelines & Evidence

Clinical Details

Section 1

When to Use

Use during early bedside triage when infection severity or treatment escalation is uncertain.

Support clinician judgement with a structured review of the highest-yield risk factors.

Standardise communication between admitting, ID, ICU, and pharmacy teams.

Section 2

Formula & Logic

Scoring Logic

Serious MRSA infection (+2)

Rapidly changing renal function (+2)

Obesity or unusual Vd (+1)

MIC >1 concern (+2)

Concurrent nephrotoxins (+1)

Trough-only monitoring currently used (+1)

Section 3

Next Steps

Clinical Actions

Interpret the result together with source control, microbiology, host factors, and trajectory.

Escalate imaging, cultures, or specialist review when the tool lands in a high-risk tier.

Reassess dynamically if the patient deteriorates or new microbiology becomes available.

Section 4

Pearls/Pitfalls

Important Caveat

This tool supports structured infectious-disease decision making but does not replace clinician judgement or local guideline pathways.
