CASE STUDY

“It's hard to quantify, right now. But at a guess, I'd say it's probably more than 50% faster, at times. It's literally that quick. We've found to be an essential practical tool. We're very satisfied.”

Bolam test meaning

What does Bolam test mean?
In practice, the Bolam test describes how courts decide whether a professional—most commonly a clinician—met the required standard of care in negligence. It asks whether the defendant acted in accordance with a responsible body of opinion within the relevant profession; if so, they are not negligent merely because others would have acted differently. The test arises from case law, Bolam v Friern Hospital Management Committee [1957] 2 All ER 118, which sets the benchmark as the ordinary competent person exercising and professing the relevant special skill. In England & Wales, Scotland and Northern Ireland, Bolam applies subject to key developments: Bolitho v City and Hackney HA [1998] AC 232 (the professional opinion relied on must withstand logical analysis) and Montgomery v Lanarkshire Health Board [2015] UKSC 11 (informed consent is judged by a patient‑centred standard on material risk, not by Bolam). The concept is also used in non‑medical professional negligence. In Ireland, the analogous approach is found in Dunne v National Maternity Hospital [1989] IR 91 (the Dunne principles), where adherence to a general and approved practice is a strong indicator of due care, subject to the court’s scrutiny of its defensibility. Irish law on informed consent has developed separately and does...

UK Supreme Court: Bolam governs what counts as ‘reasonable alternative treatments’; disclosure duty and patient choice narrowed from Montgomery (McCulloch v Forth Valley Health Board)

McCulloch and others v Forth Valley Health Board (Scotland) [2023] UKSC 26 What are the practical implications of this case? In Montgomery v Lanarkshire Health Board [2015] AC 1430, the Supreme Court confirmed that doctors must take reasonable care to make sure patients are told about any material risks of a recommended treatment, as well as any reasonable alternative or variant treatments. It explained that the materiality of a risk is assessed, among other things, by asking whether a reasonable patient would attach importance to it. In McCulloch the Supreme Court clarifies that deciding whether an alternative is a ‘reasonable’ option lies within professional medical judgment, and is therefore determined by the Bolam approach—namely the test in Hunter v Hanley 1955 SC 200 and Bolam v Friern Hospital Management Committee [1957] 1 WLR 582. The result is that patient choice has suffered. To show that not disclosing an alternative was reasonable, a doctor need only point to a reasonable body of...

Halsall v Champion: SAAMCO 'advice' established; negligence found but time-barred; TOB cannot narrow retainer; LA 1980 s14A knowledge and UCTA exclusion considered (England and Wales)

Original news Halsall & Ors v Champion Consulting Ltd & Ors [2017] EWHC 1079 (QB) What should dispute resolution lawyers take note of? Dispute resolution lawyers should note: the potentially broad consequences of the court’s conclusion that the defendants gave affirmative advice rather than merely passing on information (SAAMCO). Absent a limitation defence, they would have faced liability for all losses the claimants suffered by entering the schemes professional advisers cannot invariably depend on their terms of business (TOB) to restrict the retainer’s scope if those terms conflict with earlier clear representations On breach, the court used the Bolam test as refined by Bolitho. Yet Montgomery v Lanarkshire Health Board was not referred to, leaving uncertainty as to whether that approach still holds for negligence based on failing to warn of risks. The notion that the court need consider the claimant’s counterfactual conduct only where the negligence is a failure to advise is doubtful. The claimant must in every case...

Conway v Yeovil & UHBW: Meadows scope-of-duty limits in paediatric negligence—no duty to prevent unknown child abuse post-discharge; Bolam/Bolitho breach findings (England and Wales)

Conway (by his father and litigation friend Luke Conway) v Yeovil District Hospital NHS Trust and University Hospitals Bristol and Weston NHS Foundation Trust [2025] EWHC 2488 (KB) What are the practical implications of this case? Conway stands as a clear illustration of a court working through the Supreme Court’s principles in Meadows v Khan [2022] AC 852, though in a distinct context. In Meadows, the claimant underwent blood tests to check if she carried the haemophilia gene. She was told by doctors she was not a carrier and that any child she conceived would not have haemophilia. Her son was born with both haemophilia and autism. Had she known she was a carrier through genetic testing, rather than blood tests alone, she would not have proceeded to have a child. The issue was whether she could also recover wrongful birth damages for the costs associated with her son’s autism, a condition independent of his haemophilia. The Supreme Court held she could not, as that loss fell outside...

PRACTICE NOTES
Informed consent in UK clinical negligence: material risks and alternatives under Montgomery, reasonable options per Bolam/Bolitho and McCulloch, and causation including Chester

This Practice Note addresses the principle of self-determination, valid consent, implied consent, provision of sufficient information in line with Montgomery, and causation. A doctor may lawfully treat a patient only where consent has first been obtained. This applies whether the intervention is a straightforward test or an invasive procedure. In reality, consent disputes usually emerge after more serious, higher-risk care such as surgery. Any adult who has the mental capacity to make their own treatment choices may accept or decline care, even where refusal could result in permanent harm or death to them or to their unborn child. Nor can such treatment be justified by detaining the person as a mental patient. For additional issues on consent—emergency treatment, withdrawal, capacity, professional guidance, battery, and Human Rights Act 1998 claims—see Practice Note: Consent in clinical negligence claims—capacity and other issues. The principle of self-determination The principle of self-determination sits at the heart of medical law and consent disputes in clinical negligence. See Airedale NHS Trust v Bland...

Clinical negligence: duties owed by clinicians and others, scope of duty, and breach—Bolam/Bolitho, Montgomery, Khan v Meadows; non-delegable duties, non-patients and secondary victims
