On 25 June 2002, Jayanthi Sonny (second respondent), a 37-year-old diabetic patient with high blood pressure, presented at Clare Estate Clinic while pregnant. She was referred to Addington hospital as a high-risk patient. On 26 June 2002, an ultrasound scan at Addington hospital revealed borderline ventriculomegaly in the fetus, a soft marker for Down's syndrome. The report suggested a rescan in two weeks. Jayanthi testified that a doctor told her to return in two weeks but did not explain why or inform her of any risks. She returned to the clinic where a nurse told her the report showed nothing untoward and that only two scans were typically performed. Jayanthi did not return to the hospital for the second scan. On 22 October 2002, due to high blood pressure, she was referred to King Edward VIII hospital where cordocentesis was performed. The test incorrectly showed no chromosomal abnormality. Based on this, the Sonnys consented to a bilateral tubal ligation. On 16 November 2002, Jayanthi gave birth to a daughter with Down's syndrome. The Sonnys sued the Premier of KwaZulu-Natal and Ethekwini Municipality for damages for the cost of maintaining their child (estimated at R6.6 million) and R150,000 for the wrongful sterilization.
The appeal was dismissed with costs, including the costs of two counsel. The High Court's finding that the appellant was liable for damages arising from the birth of the child was upheld.
A medical practitioner treating a patient in the public health system has a duty to fully inform the patient of risks identified during diagnostic procedures and to explain in clear, intelligible terms the significance of those findings and the necessity of follow-up procedures. When a patient is referred back to a primary healthcare clinic for appointment-making, and there is a foreseeable risk that communication breakdowns may occur resulting in the patient not returning for critical follow-up, the doctor must take reasonable steps to ensure the patient understands the urgency and importance of the follow-up and should provide written instructions to the clinic. The standard of care requires particular sensitivity to patients' lack of sophistication and vulnerability in the public health system. Failure to meet these standards constitutes negligence where harm results. Patients who follow all instructions given to them by healthcare providers cannot be found contributorily negligent when inadequate information leads to harmful outcomes.
The Court made important observations about the constitutional imperative in public healthcare delivery: 'In our country poverty and a lack of literacy abound. Masses of our people attend public health facilities. Their lack of sophistication and the vulnerability that accompanies poverty are factors that cannot be ignored. They are entitled to be treated in the same way as patients who can afford private medical assistance. That means that they should be fully informed and should be as involved as possible in their own treatment. This does not require a drain on public resources. This case is not about the availability of material resources. It is about a doctor communicating adequately with a patient. What is required is a public health delivery system that recognises the dignity and rights of those who are compelled to use its facilities. It is that basic sensitivity that the Constitution demands.' The Court also cited with approval principles from Lord Nathan's Medical Jurisprudence regarding the duty to give clear instructions when delegating aspects of treatment to patients, and from the Canadian case Murrin v Janes regarding the duty to warn patients about the significance of symptoms.
This case is significant in South African medical negligence law for establishing clear duties of healthcare providers in the public health system to fully inform and involve patients in their treatment, particularly vulnerable and unsophisticated patients. The judgment emphasizes that poverty and lack of literacy cannot diminish the standard of care owed to patients in public facilities - they are entitled to the same level of information and involvement as private patients. The case affirms constitutional values of dignity and rights in healthcare delivery. It clarifies the duty to give clear, unambiguous instructions and to explain the significance of medical findings in intelligible terms. The judgment also demonstrates the application of the Kruger v Coetzee negligence test in the medical context, particularly regarding foreseeability of harm in systemic healthcare environments.
