Canadian clinicians must be aware of new standards of care resulting from national clinical practice guidelines, both to ensure best practice1,2 and to avoid malpractice litigation.3,4 Clinical practice guidelines can reduce successful malpractice actions through physician education and they may be used in court as evidence that the standard of care was met.5,6 The 2007 clinical practice guidelines on prenatal screening for fetal aneuploidy7 have expanded the potential for successful wrongful birth litigation and have set a new standard for family physicians, obstetricians, laboratory physicians, radiologists, geneticists, midwives, registered nurses, genetic counselors and ultrasound technicians.
The clinical practice guidelines on prenatal screening were endorsed by the Society of Obstetricians and Gynaecologists of Canada and the Canadian College of Medical Geneticists. The guidelines include the recommendation that all pregnant women be offered prenatal screening, rather than just women aged 35 years or more (Box 1),7,8 the age at which the risk of losing a fetus as a complication of an amniocentesis is equal to the risk of giving birth to a child with Down syndrome.7 This recommendation was in response to the observation that 56% of women who give birth to a child with Down syndrome are under 35 years of age.7 New sensitive and noninvasive screening strategies have made this recommendation possible.9–13 Recent clinical practice guidelines in the United Kingdom,14 Australia,15 New Zealand15 and the United States,16 have similarly recommended offering of screening for Down syndrome to all pregnant women. It is too early to evaluate the legal impact of such clinical practice guidelines in these jurisdictions.
In the past, wrongful birth claims in Canada have been successful when prenatal screening was not offered to a woman over 35 years of age who gave birth to a child with Down syndrome and who asserted that, if not for this negligence, she would have chosen to abort the fetus.17–19 For example, in one successful claim, a 37-year-old woman requested amniocentesis in her sixteenth week of pregnancy and was told by her physician that it was too late in the pregnancy.17 In another successful claim, a 36-year-old woman seeking prenatal care from her family physician was not told that he did not practice prenatal care18 and she was not referred to another physician. Canadian legal scholars have predicted that there will be an increase in this type of legal action4 and that the courts will rule against physicians if they do not offer prenatal tests if they become standard practice.20 However, according to the Canadian Medical Association Code of Ethics,21,22 duties, such as offering prenatal screening, exist alongside the duty of physicians to practice in compliance with their conscience, as long as she or he provides sufficient notice to the patient to see another physician.21,22
In this article, we aim to inform clinicians of the legal implications of the new clinical practice guidelines on prenatal screening. We also discuss the implication of these guidelines on how pregnant women may perceive prenatal screening and their pregnancies, and how people with genetic conditions, congenital anomalies and disabilities may be viewed by others and themselves.
Negligence and prenatal screening
Tort law provides compensation to those who have been harmed as a result of a breach of a legal duty.23 Negligence is the breach of legal duty that involves the creation of “unreasonable risk”24 that results in damage that could have been avoided through “reasonable care.” Determining reasonable care is often determined in court proceedings.25 The Supreme Court of Canada has held that “physicians have a duty to conduct their practice in accordance with the conduct of a prudent and diligent doctor in the same circumstances.”26 In the case of a specialist, his or her actions must be assessed in light of the conduct of other specialists “who possess a reasonable level of knowledge, competence and skill expected of professionals in Canada, in that field.”26 Although clinical practice guidelines establish the standard of care and provide evidence as to what conduct may be considered reasonable, they do not necessarily establish the legal standard of care. The ultimate determination of the legal standard of care lies with the court after consideration of all evidence.3,27
Duty of disclosure
As part of the duty to ensure informed consent, clinicians must disclose to their patients the risks associated with health conditions and medical procedures.28 This obligation arises out of the “‚special'relationship between a physician and a patient where, due to the physician's superior medical knowledge and skill, the patient must place ‚trust and confidence' in the physician.”29
What information a reasonable doctor should provide depends on the medical knowledge and practices currently available.28 Although professional practice guidelines, as supported at trial by expert testimony, can articulate the information that should be provided, courts do not base decisions in claims about lack of informed consent solely on the reasonable-doctor standard.28 Rather, they include evidence from the patient and family members about the risks of which the patient requires disclosure.28 Moreover, a burden is “placed on the doctor to show that the patient comprehended the explanation and instructions given.”30 Though some have criticized this standard as too onerous,31 it remains the law as prescribed by the Supreme Court of Canada. The patient may argue that the risks to which a reasonable patient would be likely to attach significance when deciding whether to undergo the proposed treatment, that is, that the “material risks” (as defined by the Supreme Court of Canada) were not presented or understood.32
Causation and compensable loss in wrongful birth claims
In order to be compensated in a wrongful birth litigation, the mother must demonstrate that her prenatal care provider negligently failed to offer or perform prenatal screening. She must also establish that a reasonable person in her position would have terminated the pregnancy if prenatal screening had been properly offered and performed.33
The court must ask whether the birth of a child can constitute a loss that can be compensated for.34,35 The birth must be argued to be associated with pain and suffering of the parents, as well as with their loss of income and expenses related to raising a child with a disability.36
Impact on pregnant women
With the development of amniocentesis, women can exercise reproductive choice — they can choose to avoid giving birth to a child with Down syndrome or another genetic-based condition. However, the availability of prenatal screening and the fact that it is being offered by a physician, carries normative implications about the desirability of prenatal screening.37 Further, the implication that prenatal screening is desirable may be promoted if physicians present prenatal screening as routine.38–40 The combination of this ability to choose and the legally sanctioned concept that the birth of a disabled child can constitute a harm may cause a woman to be viewed as harming a child simply by choosing to bring a disabled child to term.41,42 Rothman has argued that in the era of prenatal testing, every pregnancy may be considered tentative.38 She cautions that women may be considered bad mothers for bringing a disabled child into the world.38
Impact on disabled people
The new clinical practice guidelines about fetal aneuploidy7 state that “Screening programs should show respect for the needs and quality of life of persons with disabilities. Counselling should be nondirective and should respect a woman's choice to accept or to refuse any or all of the testing or options offered at any point in the process.” The critique of prenatal testing based on the rights of disabled people illustrates the importance of this recommendation and the challenge to following it successfully.43–47
Some argue43 that prenatal testing “sends the hurtful message that people are reducible to a single, perceived-to-be-undesirable trait”43 and when “a single trait stands in for the whole, the trait obliterates the whole.”43 Through the prenatal screening lens, disabled people may be viewed as living lives of low quality,44 despite their often-expressed views to the contrary.45 Although important progress has been made in the protection of the rights of disabled people, the practice of prenatal screening may encourage the view that it is better to prevent their existence rather than to remove the social barriers they face.41,46,48 Similarly, prenatal screening may strengthen the idea that a person should meet a certain level of “fitness” to be born.
Wrongful birth claims may contribute to the perception that the birth of a disabled child is a burden to the parents and the community as well as to the child. The law's recognition of wrongful birth actions may deny the reality that disability is largely socially constructed.41,42,44 This may have a negative impact on the psychological well-being of disabled people.49
Proponents of prenatal screening argue that in considering the financial and other costs associated with raising a child with a severe disability, it is reasonable for potential parents to consider preventing the birth.50 Further, since there are many reasons to receive prenatal screening, the practice in itself does not convey any distinct message about the value of the lives of disabled people.50,51 Some argue that objections to prenatal screening are not sufficiently distinguishable from objections to abortion.51 Similarly, those who believe wrongful birth actions are appropriate contend that they do not devalue the lives of people with disability.35,52,53
Exploring the tensions
The clinical practice guidelines on prenatal screening for fetal aneuploidy specifically expresses the need for screening programs to be respectful of women's choices regarding screening and the implications. They must also respect the needs and the quality of life of disabled people. However, if a pregnancy is terminated because of predicted anomalies, tension may exist between respect for women's reproductive choice and respect for disabled people. This tension is amplified if physicians are legally liable if they do not offer prenatal screening to all pregnant women in their care and if a child is born with a condition that could have been predetermined. Many scholars and activists concerned with the rights of disabled people strongly oppose both prenatal screening and wrongful birth claims for this reason. They are also opposed to screening and wrongful birth claims because both the guidelines and any resulting successful wrongful birth claims potentially ignore the many traits of personhood the child brings in being born, as well as the traits of personhood of those already living with disabilities in that jurisdiction and beyond.41,43,44,48
Although the increase in reproductive decisions women will face following the increase in screening will be justified as an exercise of reproductive choice, such increases may also result in more women viewing their pregnancies as tentative38 until the results of prenatal screening are known. Further, the existence of wrongful birth claims reinforces the view that the birth of a child with a disability is a harm for which one may be compensated.41
In addition to the new guidelines, there should also be professional development for clinicians about how to provide nondirective counselling29 about prenatal screening and how to be sensitive to the position of disabled people. This should include information about support networks, social programs aimed at supporting and accommodating people with disabilities and referrals to groups, families or people living with the diagnosed condition who can provide information about and options for caring for children with the condition. In addition, there should be public education about the views of the community of disabled people. Research into the effect of the new clinical practice guidelines is required and should involve clinicians, patients, disabled people, professional organizations and the public.
Conclusion
In Canada, wrongful birth claims may increase if clinicians do not practise according to the new standard of care prescribed in the 2007 clinical practice guidelines on prenatal screening for fetal aneuploidy, which includes offering prenatal screening to all pregnant women. Although these guidelines emphasizes the obligation of respect for reproductive autonomy and for disabled people, the fact that a clinician may be legally liable if prenatal screening is not offered to a pregnant woman and her child is born with a condition that could have been predetermined promotes tension between these obligations.
