REVIEW OF LITERATURE

Introduction

This chapter will discuss the literature review that was undertaken for this thesis. A review of the relevant literature will encompass an analysis of the doctrine of informed consent as applied in South Africa jurisprudence, followed by the socio-legal aspects of IC in South Africa and the potential impact of the cultural milieu and multiculturalism on IC practice in South Africa. This will be followed by an analysis of the Hippocratic tradition and the evolution of the IC doctrine, as well as a critical discussion of the philosophical concepts of autonomy from a Kantian (duty based),1010 and Millian or utilitarian1011 perspectives.1012 This is followed by analysis of the concept of patients’ rights, shared healthcare decision-making, and the rights of vulnerable population groups.
According to Polit and Beck,1013 a literature review is usually done to assist the researcher to comprehend and extend his or her knowledge regarding the phenomenon under study. It also helps the researcher to determine whether the phenomenon is worth studying and assists in determining the scope of the study, so that research can be limited to a needed area of inquiry.1014 A review of the literature may also help the researcher to determine the extent to which the topic under study is covered in the existing body of knowledge.1015 Moreover, the literature review shares with the reader the results of other studies that are closely related to the topic under study, it relates the current study to other larger and ongoing debates in the literature, in this case the medico-legal cases and analysis regarding the doctrine of IC, by filling in gaps and extending prior studies. Hence a literature review provides a framework for establishing the importance of the present study and a basis for comparison of the results of the present study to findings by other researchers working on the same phenomenon or in the same area of inquiry.1016,1017

The legal doctrine of informed consent in South Africa Constitutional rights to informed consent

Informed consent before medical procedres is a constitutionally protected right in South Africa. These constitutionally protected rights to bodily integrity and security have been tested in South African courts in the cases of Minister of Safety and Security v Gaqa1018 and Minister of Safety and Security v Xaba (hereinafter the Xaba case).1019 In both cases, the police sought a court order to compel an accused person to undergo a surgical procedure in order to extract a bullet to be used as evidence in their prosecution. In the Xaba case,1020 the court ruled that granting such an order would violate the defendant’s constitutional rights to a fair trial, bodily integrity and privacy.1021 By contrast, such an order was granted by a judge in the case of Minister of Safety v Gaqa (hereinafter the Gaqa case),1022 where the judge felt that there were grounds within the Criminal Procedure Act,1023 which allowed use of reasonable force by the police in the public interest.1024 In both cases, the defendants sought protection under the constitutionally protected rights to bodily and psychological integrity as enshrined in section 12(2) of the Constitution.1025 In the Gaqa case, Desai J granted the order for the extraction of the bullets, basing his judgment on the fact that the rights enshrined in section12 were limited rights when read together with section 36 of the Constitution, which provides that rights in the constitution could be limited by a law of general application in a democratic society.1026 The court further held that this limitation was supported by the Criminal Procedure Act,1027 which stipulates that the police could use any reasonable force to procure evidence from suspected criminals.1028 On the other hand, Southwood J denied the police the right in the Xaba case,1029 basing his decision on the rights to bodily and psychological integrity enshrined within the Constitution, arguing that the judgment in the former case was wrong in terms of section 12 of the Constitution.1030 Further, it was held that relief could not be provided by the Criminal Procedure Act since the Act did not allow forced surgical removal of an object from the body of a person.1031
Some commentators argued that the limitation of rights applied in Gaqa case by Desai J refers only to the limitation of rights in the Bill of Rights and specifies that those limitations apply “only in terms of law of a general application to the extent that the limitation is reasonable and justifiable in an open and democratic society based on human dignity, equality and freedom.”1032 The authors contend that court adjudication may not be considered a law of general application and such abrogation should probably be done via legislative mandate, as suggested by Southwood J in the Xaba case.1033
One may conclude this section by noting what has been suggested by others, namely that: “The ease with which any jurisdiction is capable of upholding patient’s rights depends on its history and jurisprudence as it does on its willingness to make appropriate modifications or enthusiasm for change.”1034 In South Africa, the constitutionally protected rights to bodily integrity and security as well as the right to IC have been codified in theNHA,1035 and further enshrined in the Constitution and disseminated in the Patients Right Charter.1036 These provisions and regulations are designed to assist in achieving the right of access to healthcare by all South African citizens. The Patients’ charter formally recognizes the patients’ right to IC during medical treatment. It has been advanced that the Charter provides an officially sanctioned baseline standard that can be referred to as tool for accountability to patients, HCPs and the broader civil society.1037 Under South African law, health related autonomy rights are constitutionally protected as outlined in section 12 of the Constitution, with section 12(1) stating that “everyone has the right to freedom and security of the person,” whilst section12(2) stipulates that:
Everyone has the right to bodily and psychological integrity, which includes the right to:

  • To make decisions concerning reproduction
  • To security in control over their body; and
  • Not to be subjected to medical and scientific experiments without their informed consent.1038

Historical origins of informed consent in South Africa

According to Van Oosten, patient consent, as a requirement for all lawful medical interventions, is a well-established principle in South African common law.1039 The earliest leading cases in this area were the cases of Stoffberg v Elliot1040 and the Esterhuizen case.1041 In the former case, a patient whose penis was wrongfully amputated without his consent sued his doctors for damages in action for assault. The court agreed that any treatment done without the necessary consent is and interference with and individuals bodily integrity and can lead to charges of assault and award of damages.1042 In the Esterhuizen case a 10-year-old child who was diagnosed with Kaposi’s sarcoma, a form of skin cancer was initially treated with superficial radiation for the condition with both parents’ consent. Later, however, because of recurrence of the tumour, she was subjected to extensive radiation therapy, which resulted in severe burns and tissue damage necessitating amputation of her limbs. This was done without the express consent of her guardians. In action for damages for assault against the treating physician, the court held that while the superficial radiation was duly performed with appropriate consent from the parents, the latter procedure was performed without full disclosure, knowledge and consent of the child’s mother although there was adequate time to obtain such consent. The court rejected the treating doctor and hospital’s argument that the fact that her grandfather and parents had brought the child to hospital and previously consented to a similar treatment implied consent for the more radical procedure. The court also rejected arguments that the treatment was in the best interests of the child. The court held rather, that because the radical treatment was vastly different from the former superficial radiation given to the child, it was necessary that the child’s mother should have been adequately informed of the dangers inherent in the radical treatment for such consent to be considered valid.1043
More recently in the Castell case,1044 it has been argued that the judgment of the court in this case seems to have introduced the prudent patient standard of information disclosure and IC into South African medical jurisprudence.1045 Further, the SCA revisited this judgement in the case of Broude v McIntosh,1046 but did not overrule this decision despite some technical reservations, thereby reaffirming the prudent patient and material risks standards as the required standard for information disclosure in South Africa.1047 The consequences of the court’s decision in the Castell case1048 on South African medical jurisprudence were that the following principles were generally accepted, according to Van Oosten: 1049

  • a shift from medical paternalism to patient autonomy
  • A shift from the ‘reasonable doctor’ standard to the ‘prudent patient’ standard
  • A shift in disclosure to the ‘material risk’ standard, where the level of disclosure required is what a reasonable patient would consider pertinent before making a decision
  • The court appears to place the patients’ informed consent within the framework of volenti non fit injuria or voluntary assumption of risk rather than delict.
    In 2004, enactment of the NHA1050 codified the requirements for IC into South African healthcare law specifying the nature and aspects of information to be disclosed prior to IC as discussed in chapters 1 and 2 of this thesis. In terms of South African common law, the issue of how much information should be disclosed to a patient has been the subject of debate starting from the case of Lymberg v Jeffries 1925,1051 where the court was of the opinion that a “doctor is not obliged to disclose all the conceivable complications that may arise during a medical procedure.” However the judgment of Ackerman J in Castell v De Greef, 1052 suggested that a doctor is obliged to warn the patient of all the ‘material risks’ inherent in the treatment, where the material risks are based on a ‘prudent patient standard’.1053 Therefore, the requirement for information disclosure in South Africa tends towards the practice in North America where libertarian rights-based autonomy is predominant. Furthermore, section 6 of the NHA requests that as part of IC, “every HCP should inform the user of the user’s health status except where it would be contrary to the user’s best interests,” which would include “the range of diagnostic procedures and treatment options available, the benefits, risks, costs and consequences generally associated with each option. The user’s right to refuse health services and the implications thereof”.1054 It may be said that this appears to reaffirm the requirement for disclosure of all material risks with appropriate exceptions.
