Should a doctor inform a pregnant woman of a 9-10% risk of harm to her baby during delivery? Is it part of the doctor’s duty to do so, no questions asked? While many readers might think that the answers to these questions are self-evident, this has by no means been clear as a matter of law throughout the United Kingdom for the last 30 years. Indeed a ‘No’ response might have been upheld by the courts if the medical profession thought it acceptable not to inform. This has now changed with the recent decision of the Supreme Court in Montgomery v Lanarkshire Health Board, which has confirmed, categorically, that the duty of care that doctors owe to patients when advising them about their care is not to be determined by reference to responsible medical practice, or the so-called Bolam test.
This position had been laid down in 1985 by the then House of Lords in Sidaway v Board of Governors of the Bethlem Royal Hospital. That case established a line of precedent that treated information disclosure cases – i.e. what patients should be told about treatment options – by reference to what the medical profession decided was appropriate. Tellingly, in Sidaway the term ‘patient autonomy’ was never even used. The lone voice in the judgment was Lord Scarman who referenced the importance of self-determination and took as his fundamental premise “…the patient's right to make his own decision, which may be seen as a basic human right protected by the common law.” [p. 882]. In contrast, all other judges, in one form or another, endorsed a position of medical paternalism that has held sway ever since.
In 2015, however, the Supreme Court has roundly rejected the paternalistic position in Sidaway as “unstatisfactory”; indeed, it has gone further in condemning the suggestion therein that a doctor need only answer direct questions as “profoundly unsatisfactory”. Rather, it has confirmed and reiterated Lord Scarman’s position all those years ago as one that now correctly reflects the appropriate legal standard of care that patients can expect from their doctors. The grip of the professionally oriented Bolam test has been released.
While it is true that the tectonic plates of precedent have been moving in this direction in recent years this has largely been driven by the lower courts in England and Wales. Montgomery, on appeal from the Inner House of the Court of Session in Scotland, represents the most authoritative and damning rejection of the Bolam test to consent to medical treatment across the UK. Subject to refinements by the Court of Appeal in Pearce v United Bristol Healthcare NHS Trust and the High Court of Australia in Rogers v Whitaker, Lord Scarman’s position now prevails. The Supreme Court expressed it thus:
“An adult person of sound mind is entitled to decide which, if any, of the available forms of treatment to undergo, and her consent must be obtained before treatment interfering with her bodily integrity is undertaken. The doctor is therefore under a duty to take reasonable care to ensure that the patient is aware of any material risks involved in any recommended treatment, and of any reasonable alternative or variant treatments. The test of materiality is whether, in the circumstances of the particular case, a reasonable person in the patient's position would be likely to attach significance to the risk, or the doctor is or should reasonably be aware that the particular patient would be likely to attach significance to it.” [para 87]
In doing so, the Court drew the all important distinction between matters exclusively within the purview of professional skills and expertise, such as assessing possible investigatory or treatment options, and the duty to discuss with the patient any recommended interventions, the available alternatives, and the risks of injury that might be involved. It is this last duty that now characterises the information disclosure obligation of health care professionals to patients as a matter of the promotion of the own autonomy. Among other things, it involves:
- The duty to take reasonable care to inform the patient of material risks inherent in any treatment.
- The duty to avoid exposing the patient to a risk that she or he would otherwise avoid.
- The duty to support the patient in deciding whether or not to incur that risk.
The Supreme Court clarified three more matters:
- assessment of materiality of risk should not be seen as a pure percentage exercise – it involves a far wider range of considerations than statistical probability;
- the discharge of the above duties necessitates effective dialogue between doctor and patient, ensuring the patient is in a position to make a meaningful and genuine exercise of autonomy;
- while a therapeutic exception remains – i.e. when a health care professional reasonably assesses that it would be detrimental to the health of a patient to disclose, this exists logically subordinate to the autonomy rule and cannot subvert that rule “…to prevent the patient from making an informed choice where she is liable to make a choice which the doctor considers to be contrary to her best interests.” [para 91]
