Abstract

Machine learning is used increasingly in clinical care to improve diagnosis, treatment selection, and health system efficiency. Because machine-learning models learn from historically collected data, populations that have experienced human and structural biases in the past-called protected groups-are vulnerable to harm by incorrect predictions or withholding of resources. This article describes how model design, biases in data, and the interactions of model predictions with clinicians and patients may exacerbate health care disparities. Rather than simply guarding against these harms passively, machine-learning systems should be used proactively to advance health equity. For that goal to be achieved, principles of distributive justice must be incorporated into model design, deployment, and evaluation. The article describes several technical implementations of distributive justice-specifically those that ensure equality in patient outcomes, performance, and resource allocation-and guides clinicians as to when they should prioritize each principle. Machine learning is providing increasingly sophisticated decision support and population-level monitoring, and it should encode principles of justice to ensure that models benefit all patients.

  • Transparent decision-making processes in healthcare AI, with patients and providers understanding the rationale behind AI-driven recommendations, foster trust and accountability.

    “Transparent decision-making processes are vital in healthcare AI. Patients and healthcare providers must understand the rationale behind AI-driven recommendations, fostering trust and accountability.[23]”

    From Ethical implications of AI and robotics in healthcare: A review (2023) · cites this paper as [23]

    The “What Is Machine Learning?” section says complex models can be hard to understand and trust, supporting a link between understandability and trust. The Abstract recommends involving stakeholders in model design. Neither passage says patients and providers must understand the rationale for individual AI recommendations or that doing so fosters accountability (pages not provided in our copy). (LLM, conf=0.82)

  • Participatory approaches play a vital role in bridging the gaps between model development and deployment and in promoting fairness in ML applications.

    “Participatory approaches play a vital role in bridging the gaps between model development and deployment and in promoting fairness in ML applications (Rajkomar et al., 2018).”

    From The BigScience ROOTS Corpus: A 1.6TB Composite Multilingual Dataset (2023) · cites this paper as Rajkomar et al., 2018

  • SDoH variables reflect structural inequities, and model outputs using them could inadvertently reinforce disparities if misapplied.

    “Because SDoH variables reflect structural inequities, there is a risk that model outputs could inadvertently reinforce disparities if misapplied [91,92].”
  • How principles of algorithmic fairness might apply in clinical decision-making has received little attention in the medical literature.

    “how principles of algorithmic fairness might apply in clinical decision-making has received little attention in the medical literature7,8.”
  • One of the main challenges to develop trustworthy AI is to define the meaning of fairness in machine learning practice.

    “One of the main challenges to develop trustworthy AI is to define the meaning of fairness in the practice of machine learning111.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
