(a)
Health risk scores
40.
Artificial intelligence can be utilized to create health risk scores for a variety of
purposes in health care, including medical diagnosis and care planning. Racially
discriminatory effects can occur when such algorithms are used to allocate health-care
resources, because of algorithmic design and the data used to train artificial intelligence
systems. There are cases in which such algorithms have been designed to identify who should
qualify for extra care, using previous health-care costs as a proxy for medical needs. The data
on which such decisions are based can be influenced by previous lack of adequate access to
health care among those from marginalized racial and ethnic groups in the context of systemic
racism, as well as different disease patterns due to disparities in the socioeconomic
determinants of health.

In the United States, a calculator was developed to assist health-care providers in
assessing the likelihood of successful vaginal birth after caesarean delivery. A study in 2019
revealed bias in the calculator’s foundational algorithm. The calculator had two race-based
correction factors, which resulted in lower predicted vaginal birth success rates for women
of African descent and Hispanic women compared with white women with similar
characteristics. Because of these correction factors, the calculator potentially worsened racial
disparities in maternal health outcomes by discouraging clinicians from offering vaginal birth
to women of African descent and Hispanic women, leading to higher rates of caesarean
sections.62
(b)
Disease detection
42.
Another application of artificial intelligence technologies is disease detection,
including cancer detection.63 Artificial intelligence systems trained on extensive data sets
comprising thousands or millions of images, including radiological scans, pathology images
and photographs, can learn to distinguish between normal and cancerous lesions. 64 This
deployment of artificial intelligence can significantly aid in early cancer detection, potentially
saving lives while improving health-care system efficiency. However, those from
marginalized racial and ethnic groups may not benefit equally from such advancements due
to the algorithms not being generalizable to patient populations that are not adequately
represented in the training data. Researchers have suggested that the use of artificial
intelligence algorithms for skin cancer detection shows poorer performance for individuals
with darker skin tones because many of the publicly available image data sets used to train
them are biased, with a lack of diversity in skin tones and ethnic backgrounds.65 For example,
a survey of 21 open-access skin lesion data sets, containing over 100,000 images, revealed a
significant underrepresentation of images of darker skin.66

Artificial intelligence-enabled medical devices
43.
Artificial intelligence is being developed and utilized alongside other developments
in health-care technologies, including health-care devices. Many of these devices are
artificial intelligence-enabled, and racial bias can become embedded in their operation. For
example, in the United Kingdom, a report showed that bias was baked into the operation of
medical devices at all stages of their development, including during phases involving
algorithm development and machine learning. During the coronavirus disease (COVID-19)
