How Algorithms Affect Medical Treatment for African Americans

In recent years, the healthcare industry has increasingly embraced algorithms and artificial intelligence (AI) to enhance medical decision-making, predict patient outcomes, and streamline treatment processes. However, while these technological advancements hold great promise, they also present significant challenges, particularly for African American patients. This post explores the ways in which algorithms impact medical treatment for African Americans, highlighting both the potential benefits and the critical concerns regarding bias and inequality.

The Promise of Algorithms in Healthcare

Algorithms in healthcare are designed to analyze vast amounts of data, identify patterns, and support clinical decision-making. They can assist in diagnosing diseases, recommending treatments, predicting patient outcomes, and personalizing care plans. The advantages of using algorithms include:

  1. Improved Accuracy: Algorithms can process and analyze data more quickly and accurately than humans, reducing the likelihood of errors.

  2. Early Detection: Predictive algorithms can identify early signs of diseases, allowing for timely intervention and potentially better outcomes.

  3. Personalized Treatment: By analyzing individual patient data, algorithms can help tailor treatments to meet specific needs, potentially improving efficacy.

Challenges and Concerns

Despite their potential, algorithms in healthcare can perpetuate and even exacerbate existing disparities, particularly for African American patients. Several key issues contribute to this problem:

1. Data Bias

Algorithms are only as good as the data they are trained on. If the data used to develop these algorithms is biased or unrepresentative, the resulting models can reinforce existing inequalities. Historically, African Americans have been underrepresented in medical research and clinical trials, leading to a lack of comprehensive data for this population.

2. Racial Bias in Healthcare Data

Healthcare data often reflects existing racial biases within the medical system. For example, African American patients may receive different treatments or experience different outcomes due to systemic biases in healthcare delivery. When algorithms are trained on this biased data, they can inadvertently learn and perpetuate these biases.

3. Socioeconomic Factors

Many algorithms fail to account for socioeconomic determinants of health, such as income, education, and access to healthcare, which disproportionately affect African American communities. Ignoring these factors can lead to inaccurate predictions and recommendations that do not consider the broader context of patients' lives.

Examples of Algorithmic Bias

1. Kidney Disease

An example of algorithmic bias is the use of race-based adjustments in estimated glomerular filtration rate (eGFR) calculations for kidney function. Historically, eGFR algorithms have included a race correction factor that can overestimate kidney function in African Americans, potentially delaying necessary treatments.

2. Cardiovascular Risk

Some cardiovascular risk assessment algorithms have been found to underestimate the risk for African American patients, leading to inadequate preventive measures and interventions. This can result in higher rates of undiagnosed and untreated heart disease within this population.

Addressing Algorithmic Bias

To ensure that algorithms in healthcare benefit all patients equitably, several measures must be taken:

1. Diverse and Inclusive Data

Healthcare organizations and researchers must prioritize the inclusion of diverse populations in medical research and data collection. This includes ensuring that African Americans and other minority groups are adequately represented in clinical trials and datasets.

2. Bias Detection and Mitigation

Developers should implement methods to detect and mitigate bias in algorithms. This includes regular audits, fairness assessments, and the use of bias-reduction techniques during the development and deployment of models.

3. Socioeconomic and Environmental Considerations

Algorithms should incorporate socioeconomic and environmental factors to provide a more holistic view of patients' health. This can help ensure that recommendations are tailored to the unique circumstances of African American patients.

4. Transparency and Accountability

Healthcare organizations must be transparent about how algorithms are developed and used. Clear guidelines and accountability measures should be established to monitor the impact of these technologies on different patient populations.


While algorithms and AI hold significant promise for advancing healthcare, it is crucial to address the biases and disparities that can arise from their use. By prioritizing diversity in data, implementing bias detection and mitigation strategies, and considering broader social determinants of health, we can ensure that these technologies contribute to equitable medical treatment for African Americans and all patients. The goal should be to leverage the power of algorithms to enhance, rather than hinder, health equity.
