Equation & limitations
- Equation
- Age points (men = age; women = age − 10) + nursing home +10; comorbidities: neoplastic +30, liver +20, CHF +10, cerebrovascular +10, renal +10; findings: AMS +20, RR≥30 +20, SBP<90 +20, temp extremes +15, HR≥125 +10
- Version
- Fine (PORT) PSI 1997 — ABRIDGED: lab and imaging components omitted
- Source
- Fine MJ, et al. A prediction rule to identify low-risk patients with community-acquired pneumonia. N Engl J Med. 1997;336:243–250. Abridgement is by Pharmapedia.
- Appropriate in
- Reference for adults with community-acquired pneumonia. This abridged points count is a partial score only.
- Limitations
- LABS AND IMAGING ARE NOT INPUTS HERE, so the total is a LOWER BOUND of the true PSI and CANNOT be mapped to PSI risk classes.
- The full PSI adds points for pH<7.35, BUN≥30, Na<130, glucose≥250, Hct<30, pO2<60 and pleural effusion.
- Do not use this abridged total for site-of-care or mortality decisions — it will under-estimate risk.
For educational use. Results support, and do not replace, clinical judgement — check them against the patient and local guidelines.
