CAHP Cardiac Arrest Hospital Prognosis Score

Clinical score predicting neurological outcome (CPC 1 or 2 at 30 days) in patients resuscitated from out-of-hospital cardiac arrest. Based on 8 variables at ED arrival. Validated in French multicentre cohorts. Low score indicates favourable neurological outcome.

Score interpretation

Low CAHP — Favourable Outcome Likely 0–150

CAHP 150 or below — higher probability of good neurological outcome (CPC 1 or 2 at 30 days)

→ Continue post-cardiac arrest care; targeted temperature management (32 to 36 degrees C for 24 hours) if comatose after OHCA; coronary angiography if shockable rhythm or ischaemic aetiology suspected; frequent neurological assessment; avoid hypoxia (SpO2 94 to 98%), hypotension (MAP above 65), hyperthermia, and hyperglycaemia; EEG if seizure activity

High CAHP — Poor Outcome Expected ≥ 151

CAHP above 150 — poor neurological outcome predicted at 30 days

→ Continue resuscitation care but initiate goals of care discussion; multimodal neuroprognostication required (EEG, CT or MRI brain, somatosensory evoked potentials, NSE) — do NOT withdraw treatment on CAHP score alone; wait at least 72 hours post-ROSC before prognostication; ethics and palliative care consultation if withdrawal of life-sustaining treatment is considered; senior intensivist and neurologist involvement; document all family discussions
