NELA Risk Score (Emergency Laparotomy)

National Emergency Laparotomy Audit (NELA) risk model predicts 30-day mortality for emergency laparotomy. Mandated for all emergency laparotomies in England and Wales.

Score interpretation

Predicted mortality <5% (low risk)

→ Standard emergency care; ward or surgical HDU post-op; consultant surgeon and anaesthetist involvement; antibiotic prophylaxis; VTE prevention

Predicted mortality 5-15% (moderate risk)

→ HDU/Level 2 care post-op; ICU review; consultant surgeon and anaesthetist mandatory; goal-directed fluid therapy; critical care outreach; family consent with numerical risk

Predicted mortality >15% (high risk)

→ ICU admission post-op; senior surgeon + senior anaesthetist; goals of care discussion (patient/family); palliative option if patient declines; formal NELA data submission required; avoid surgical delay >2h if <5% risk difference
