When should I use the PSI PORT Score?

Use the PSI PORT Score when you need a structured infectious-disease assessment to support bedside triage, escalation, or follow-up decisions. It should complement, not replace, clinical judgement and local guideline pathways.

Does the PSI PORT Score replace specialist review?

No. The PSI PORT Score helps standardize risk assessment and communication, but specialist input, microbiology data, imaging, and patient trajectory still drive final management.
