# Algorithmic Bias in Care

Addressing systematic errors in AI models that predict mortality risk and guide end-of-life decisions
- Technology Readiness Level: 5/9
- Impact: 5/5
- Investment: 3/5
The increasing deployment of artificial intelligence in healthcare has brought algorithmic bias to the forefront of medical ethics, particularly in end-of-life care settings where predictive models influence critical decisions about palliative interventions, hospice referrals, and resource allocation. Algorithmic bias in care refers to systematic errors or unfair outcomes that emerge when machine learning models used to predict mortality risk, assess care needs, or recommend treatment pathways reflect historical inequities embedded in their training data. These systems typically analyse vast datasets of electronic health records, demographic information, and clinical outcomes to identify patterns that inform care decisions. However, when training data overrepresents certain populations or reflects past discriminatory practices—such as differential treatment patterns based on race or socioeconomic status—the resulting algorithms can perpetuate or even amplify these disparities. The technical mechanisms of bias detection involve statistical auditing techniques that examine model performance across different demographic groups, fairness metrics that quantify disparate impact, and interpretability methods that reveal which features drive predictions for various patient populations.

The healthcare industry faces a profound challenge in ensuring that AI-driven decision support systems do not exacerbate existing inequities in end-of-life care access. Research suggests that mortality prediction algorithms trained on historical data may underestimate the palliative care needs of minority populations or lower-income patients, who have historically received less aggressive end-of-life interventions regardless of their preferences or clinical needs. This creates a troubling feedback loop where algorithmic recommendations reinforce patterns of underservice. The problem extends beyond simple prediction accuracy to encompass questions of fairness definitions—whether algorithms should achieve equal accuracy across groups, equal access to recommended interventions, or equal outcomes. Healthcare systems implementing these technologies must grapple with the tension between optimising overall predictive performance and ensuring equitable treatment across diverse patient populations. Bias mitigation strategies address these challenges through pre-processing techniques that rebalance training data, in-processing methods that incorporate fairness constraints during model development, and post-processing adjustments that calibrate predictions to achieve equity goals.

Early deployments of bias detection frameworks in clinical settings have revealed significant disparities in how mortality prediction models perform across demographic groups, prompting healthcare institutions to establish algorithmic fairness review processes before implementing AI-driven care planning tools. Some academic medical centres have begun conducting regular algorithmic audits that examine whether palliative care referral recommendations differ systematically by patient race, insurance status, or geographic location when controlling for clinical factors. Industry analysts note growing regulatory attention to algorithmic fairness in healthcare, with emerging guidelines requiring transparency in how AI systems influence end-of-life care decisions and documentation of bias testing procedures. The development of standardised fairness metrics specific to palliative care contexts represents an important step toward ensuring that technological advancement in mortality prediction does not come at the cost of equitable access to dignified end-of-life support. As healthcare systems increasingly rely on algorithmic decision support to manage growing palliative care demands amid resource constraints, addressing bias in these systems becomes essential not only for ethical practice but for maintaining public trust in AI-assisted care. The trajectory points toward integrated approaches that combine technical bias mitigation with human oversight, ensuring that algorithms serve as tools for expanding equitable access to compassionate end-of-life care rather than mechanisms that perpetuate historical inequities.
