Medical negligence (medical malpractice) claims are among the most complex and highest-value cases in personal injury law. The claimant must prove two elements: that the healthcare provider breached the standard of care, and that the breach caused the injury. Values range from five figures for minor complications to eight figures for catastrophic birth injuries — but many jurisdictions cap the non-economic component.
Minor medical error: $50K–$150K (US), £10K–£50K (UK). Serious injury from negligence: $250K–$1M (US), £50K–£250K (UK). Catastrophic (birth injury, fatal): $1M–$10M+ (US), subject to state caps. UK/Ireland: JCG/PIAG + uncapped economic damages. Key challenge: proving causation requires expensive expert evidence.
Proving medical negligence
| Element | What must be proved | Evidence required |
|---|---|---|
| Duty of care | Doctor-patient relationship existed | Medical records showing treatment |
| Breach | Treatment fell below accepted standard | Expert opinion from same-specialty practitioner |
| Causation | The breach caused the injury (but-for test) | Expert opinion establishing causal link |
| Damages | Quantifiable harm resulted | Medical records, economic reports, life-care plans |
US values and caps
| Outcome | Range (total) | Cap impact |
|---|---|---|
| Minor complication (resolved) | $50,000–$150,000 | Below most caps |
| Serious injury (surgery, disability) | $250,000–$1,000,000 | Non-economic may hit MICRA/state cap |
| Catastrophic (permanent disability) | $1,000,000–$5,000,000 | Cap limits non-economic; economic uncapped |
| Fatal / birth injury | $2,000,000–$10,000,000+ | Lifetime care costs dominate (uncapped) |
UK values
Medical negligence claims in England and Wales are valued using the same JCG framework as other personal injury claims — by injury type and severity. There is no specific cap for medical negligence. The NHS Litigation Authority (now NHS Resolution) handles claims against NHS trusts and publishes annual reports on claim costs.
Ireland values
Medical negligence claims in Ireland do not go through PIAB — they proceed directly to court. Awards are assessed using the Personal Injuries Guidelines. Expert evidence from both liability and causation perspectives is required.
Canada values
Non-pecuniary damages are subject to the Andrews cap (~C$400K–$420K for catastrophic cases). Economic damages — future care costs, lost earning capacity — are uncapped and typically constitute the majority of the total award in severe medical negligence cases.
Procedural requirements
- US: Many states require a certificate of merit or expert affidavit before filing suit
- US: Some states require pre-suit notice to the healthcare provider (60–180 days)
- US: Shorter statutes of limitations than general personal injury in many states
- UK: 3-year limitation period; Pre-Action Protocol for clinical disputes
- Ireland: 2-year limitation period; direct court proceedings (no PIAB)
Birth injury claims
Birth injury claims — cerebral palsy from delayed delivery, Erb's palsy from shoulder dystocia, hypoxic-ischaemic encephalopathy — produce the highest total awards in medical negligence because of the combination of maximum non-economic damages and decades of future care costs for a young child.
