Medical Misdiagnosis Claims in Malaysia

Bolam-Bolitho standard · Six-year limitation · Independent expert evidence

Misdiagnosis is one of the most common forms of medical negligence claim in Malaysia. The principal categories are: failure to diagnose cancer, failure to diagnose stroke, failure to diagnose ectopic pregnancy or sepsis, misdiagnosis of cardiac events, and misinterpretation of imaging studies. The legal framework is the Bolam-Bolitho composite standard as adopted in Foo Fio Na v Dr Soo Fook Mun [2007] 1 MLJ 593, with limitation under the Limitation Act 1953 (six years from date of damage or knowledge).

The Bolam-Bolitho test in misdiagnosis cases

The doctor is not negligent in diagnosing if they acted in accordance with a practice accepted as proper by a responsible body of medical opinion (Bolam), provided that opinion withstands logical analysis (Bolitho). Misdiagnosis claims therefore turn on whether a competent doctor in the same specialty, with the same information available, would have reached the correct diagnosis.

Common misdiagnosis claim categories

Cancer misdiagnosis — failure to act on suspicious imaging, delayed referral to oncology, missed early-stage tumours
Stroke misdiagnosis — failure to recognise FAST signs, delayed thrombolysis
Ectopic pregnancy — misdiagnosis as appendicitis or other abdominal pathology
Sepsis — failure to recognise early septic deterioration
Cardiac event — missed or atypical myocardial infarction (especially in women, diabetics)
Imaging misinterpretation — missed fractures, missed cancers on CT/MRI/X-ray
Paediatric misdiagnosis — missed meningitis, missed appendicitis in young children

Causation — the harder hurdle

Even where breach is established, the claimant must prove that the misdiagnosis materially caused the injury. In cancer cases this requires expert evidence on stage progression and prognosis at the date of breach versus diagnosis. In stroke cases, time-windows for thrombolysis matter. The expert evidence on causation is often the most difficult and expensive part of the case.

Limitation

Six years from the date of damage. For misdiagnosis with delayed effects (e.g., progression of an undiagnosed cancer), the clock typically runs from the date the correct diagnosis is made, not the original misdiagnosis date.

Frequently Asked Questions

My doctor missed a cancer that was later found by another doctor. Do I have a claim?

Possibly. The question is whether a reasonable doctor in the same position with the same information would have made the diagnosis. Independent expert review is the next step. Limitation runs from the date of correct diagnosis.

How much can I claim for misdiagnosis?

Damages depend on the harm caused (life expectancy reduction, pain and suffering, loss of income, future medical costs). Cancer-progression cases can yield substantial awards (RM500,000 to RM2m+). Less severe misdiagnosis without long-term consequence yields smaller awards.

Can I sue a government hospital?

Yes — vicariously through the Government of Malaysia under the Government Proceedings Act 1956. Notice and procedural requirements differ from private hospital claims.
