The Duty of Care and Clinical Negligence

The application of the law of negligence to medical practice raises distinctive issues of policy and principle that have required the courts to develop a body of doctrine that accommodates both the need to protect patients from substandard care and the legitimate interest of the medical profession in maintaining clinical freedom.¹ The standard of care in clinical negligence cases has been shaped by the Bolam principle and its subsequent qualification in Bolitho v City and Hackney Health Authority, and the interplay between these two authorities continues to determine the conditions under which medical defendants may successfully resist liability.

In Bolam v Friern Hospital Management Committee, McNair J directed the jury that a doctor is not guilty of negligence if he acts in accordance with a practice accepted as proper by a responsible body of medical men skilled in that particular art, even if other practitioners would have adopted a different approach.² The significance of the Bolam test lies in its deference to professional consensus: provided the defendant can identify a body of responsible professional opinion that would have acted as they did, liability will not attach even if a different, and perhaps preferable, approach was available.

The three-stage duty of care framework established in Caparo Industries plc v Dickman requires foreseeability of damage, a relationship of proximity, and that it be fair, just, and reasonable to impose a duty.³ In the medical context, these requirements are readily satisfied in the relationship between clinician and patient, and the duty of care is not ordinarily in dispute. The contested issue is invariably the standard of that duty and whether a breach has occurred.

The Bolam test was significantly qualified by the House of Lords in Bolitho v City and Hackney Health Authority, where Lord Browne-Wilkinson held that the court is not bound to hold that a defendant clinician escapes liability merely because evidence is called from a number of medical experts who are of opinion that the defendant's conduct was within acceptable clinical practice.⁴ The court retains the power to scrutinise professional opinion and to reject it where it cannot withstand logical analysis. This qualification represents a meaningful, if limited, judicial incursion into the territory of clinical judgment and serves as an important safeguard against the risk that defendants might construct expert evidence to legitimise any substandard practice.

In conclusion, the standard of care in clinical negligence represents a carefully calibrated balance between judicial oversight and professional autonomy. The Bolam test continues to afford considerable protection to medical defendants, but the Bolitho qualification ensures that this protection is not unlimited. The ongoing challenge for the courts is to apply this framework in a way that holds clinicians accountable for genuinely substandard care without deterring legitimate clinical innovation or generating defensive medicine.
