⚕️ A medical error caused lasting harm — how do I claim compensation?

Direct answer

Two separate tracks: a complaint about the care (which does not pay money) and a compensation claim, which in most EU countries goes first to a no-fault or patient-injury scheme — AvMA — Action against Medical Accidents / NHS Resolution (0345 123 2352) — that pays for avoidable harm without proving anyone was negligent, faster and without court. Request your full medical records first; they are the evidence. Parliamentary and Health Service Ombudsman (PHSO) (0345 015 4033) handles the complaint about the treatment; Civil Legal Advice / Citizens Advice / Law Centres (0345 345 4 345) advises on a court claim where the scheme does not apply, and on deadlines, which are usually three years from knowing about the harm.

🗣️ What to say

"On [date] I was treated at [place] for [condition]. As a result of [what went wrong] I now have [lasting harm]. I request a copy of my complete medical records and file a claim for compensation for avoidable injury."

🪜 Step by step

  1. Records firstFull file, including nursing notes and imaging. You have a right to a copy within a month.
  2. Independent opinionA second doctor's view on whether the harm was avoidable. Patient organisations know who does these assessments.
  3. Scheme claim: AvMA — Action against Medical Accidents / NHS ResolutionForm, records, the harm and its consequences. No lawyer needed; the scheme investigates.
  4. Complaint: Parliamentary and Health Service Ombudsman (PHSO)In parallel — it improves care and its findings help the claim.
  5. Court or insurer: Civil Legal Advice / Citizens Advice / Law CentresWhere the scheme does not cover (private care in some countries), the provider's liability insurer, then court. Watch the three-year deadline.

❓ Frequently asked

Do I need to prove negligence?

Under a patient-injury scheme, no — only that the injury was avoidable with the best available care. In court, yes; that is why the scheme goes first where it exists.

What can I claim?

Medical costs, lost income, care, adaptations, and pain and suffering. Keep every receipt from day one.

The hospital offered a small settlement

Get the independent opinion before signing; a settlement usually waives everything. Legal aid can review it.
