P-POSSUM Score (Perioperative Mortality Risk)

Portsmouth POSSUM (Physiological and Operative Severity Score for Enumeration of Mortality and Morbidity) predicts 30-day surgical mortality in abdominal surgery.

Score interpretation

Low perioperative risk (<3% mortality)

→ Proceed with standard pre-op work-up; routine monitoring; senior review for complex cases

Moderate perioperative risk (3-10%)

→ Senior surgeon involvement; HDU post-op; ICU booking; anaesthetic pre-assessment; optimise comorbidities; informed consent with numerical risk

High perioperative risk (>10% mortality)

→ MDT discussion; consultant anaesthetist mandatory; ICU bed pre-booked; weigh surgery risk vs conservative management; frank consent; consider palliative/conservative pathway if patient wishes

Interpretation bands for the P-POSSUM Score. Apply clinical judgement and local guidance.
