Frequently asked questions

Can I “watch and wait” a mild head injury on anticoagulants?
Be cautious: NG232 highlights the need for ED assessment/CT decision pathways in anticoagulated patients because intracranial bleeding can be occult early. If in doubt, escalate.
Is this guideline adult-only?
No — NG232 covers babies, children, young people, and adults.
