Racism and Racial Bias in Healthcare: A Scientific and Historical Perspective

Introduction

Health is often described as a human right. Yet, for millions, access to equitable healthcare remains elusive, undermined by racism and structural bias embedded in the medical system. The intersection of race and medicine is not only a contemporary issue; it is rooted in centuries of discriminatory practices and pseudoscientific beliefs that continue to influence healthcare delivery today.

This blog post explores the history of racism in medicine, the science documenting its effects, and the urgent need for systemic change in modern healthcare.

Part I: Examples of Historical Foundations of Racism in Medicine

1. Slavery and Medical Experimentation

During slavery in the United States, Black bodies were exploited for medical experimentation. Enslaved people were often used without consent in clinical trials, surgeries, and anatomical studies.

Dr. J. Marion Sims, known as the “father of modern gynecology,” developed surgical techniques by operating on enslaved Black women without anesthesia, under the belief that Black people felt less pain.
The 19th-century belief in biological racial differences was used to justify slavery and medical abuse. Black people were falsely thought to have higher pain thresholds and thicker skin – myths that still influence clinical judgments today.

2. The Tuskegee Syphilis Study (1932–1972)

One of the most infamous examples of medical racism, the Tuskegee Study involved the U.S. Public Health Service observing the natural progression of syphilis in Black men in Alabama without providing them with treatment, even after penicillin became the standard cure. Participants were misled and denied care, leading to needless suffering and death.

3. The Exploitation of Henrietta Lacks (1951)

Henrietta Lacks was a Black woman whose cancer cells, taken without her knowledge or consent, became one of the most important tools in modern medicine. Known as HeLa cells, they were the first immortal human cell line ever grown in a lab, and have been used in countless scientific breakthroughs, including the development of the polio vaccine, cancer research, and in vitro fertilization.

However, Lacks and her family were never informed that her cells were being used in research or commercialized. For decades, they received no recognition, compensation, or even basic information about the role Henrietta’s cells played in global science.

This case reflects how Black patients have historically been excluded from decision-making, consent, and ownership over their biological data – issues that remain relevant today in genomics and biobanking.

Why it matters:

Henrietta Lacks’ story highlights not only unethical medical practices, but also enduring questions about consent, race, and bioethics in research involving marginalized communities.

Part II: Examples of Scientific Evidence of Modern-Day Racial Bias in Healthcare

Racial bias in healthcare is not a relic of the past – it is measurable, persistent, and deadly.

1. Disparities in Diagnosis and Treatment

Research has shown that racial and ethnic minorities often receive:

Less pain medication than white patients for the same conditions.
Delayed diagnoses or misdiagnoses, particularly for diseases like cancer and cardiovascular conditions.
Fewer referrals for advanced treatments, including surgery or specialist care.

Scientific studies:

A 2016 study published in Proceedings of the National Academy of Sciences found that many medical students and residents held false beliefs about biological differences between Black and white patients, leading to biased pain treatment.
A 2020 JAMA Network Open study showed that Black children with appendicitis were less likely than white children to receive opioid pain relief in emergency departments.

2. Maternal Mortality and Birth Outcomes

Black women in the U.S. are three to four times more likely to die from pregnancy-related causes than white women – a disparity that persists regardless of income or education.

Factors contributing to this include:

Implicit bias from healthcare providers.
Inadequate prenatal care access.
Dismissal of patient-reported symptoms.

Notably, Serena Williams’ post-childbirth complications, despite her fame and resources, highlighted how even high-profile Black women are vulnerable to systemic neglect.

3. Algorithmic and Technological Bias

Even healthcare algorithms can perpetuate bias. A 2019 study in Science found that a widely used algorithm underestimated the health needs of Black patients, allocating fewer resources than to white patients with similar or even fewer health issues.

Part III: Root Causes and Systemic Issues

Racial bias in healthcare is reinforced by:

Structural racism: Segregated housing, environmental injustice, and unequal access to education all contribute to health disparities.
Medical education: Curricula often neglect social determinants of health or fail to address implicit bias.
Lack of representation: Minorities are underrepresented in medical leadership, research, and clinical trials, which can skew data and decisions.

Part IV: Solutions and the Path Forward

1. Bias Training and Cultural Competency

While not a panacea, evidence suggests that targeted anti-racism and implicit bias training for healthcare providers can improve patient-provider interactions and reduce disparities.

2. Diversifying the Workforce

Studies show that patients often receive better care when treated by providers of similar racial or ethnic backgrounds. Supporting minority students in medicine and nursing can help bridge this gap.

3. Community-Based Interventions

Community health workers, peer support programs, and local clinics have proven effective in addressing health inequities, especially in underserved populations.

4. Policy and Advocacy

Efforts must extend beyond the clinic. Policies addressing environmental racism, equitable insurance access, and social determinants of health are critical. The Affordable Care Act and Medicaid expansion have helped narrow some gaps, but more systemic reform is needed.

Conclusion

Racism in medicine is not just a historical scar, it is an ongoing public health crisis. Addressing it requires confronting uncomfortable truths, investing in systemic change, and reimagining healthcare as a space of equity and justice for all.

As individuals, clinicians, researchers, and policymakers, we have a collective responsibility to dismantle racial bias in healthcare because no one should be denied care, dignity, or life based on the color of their skin.
