Medical bias refers to the preconceived notions and prejudices that healthcare professionals may hold towards patients based on various attributes such as race, ethnicity, gender, age, socioeconomic status, or disability. These biases can manifest in numerous ways, from diagnostic decisions to treatment recommendations and patient interactions. Understanding medical bias involves recognizing that these biases are often subtle and ingrained, influenced by societal norms and personal experiences. The impact of medical bias in healthcare is profound and multifaceted, leading to disparities in healthcare access, quality, and outcomes. For example, research has consistently shown that minority patients often receive lower-quality care and experience worse health outcomes compared to their white counterparts. Healthcare professionals should be aware of their biases and work towards overcoming them through various methods such as partnering with patients, promoting self-awareness, diversifying the healthcare workforce, and implementing standardized clinical guidelines.

What You'll Learn

Racial bias
Research has consistently found low to moderate levels of implicit racial/ethnic bias among healthcare professionals. These biases are similar to those held by the general population and often result in negative attitudes towards people of colour, particularly those who are Black, Hispanic/Latino/Latina, or dark-skinned. The impact of these biases is significant, affecting patient-provider interactions, treatment decisions, treatment adherence, and ultimately, patient health outcomes.
For example, studies have shown that Black patients are more likely to be discharged early from the hospital after surgery, increasing their risk of adverse health outcomes. They are also less likely to receive radiation therapy or mastectomies following a cancer diagnosis. Additionally, Black patients with bipolar disorder are more likely to be prescribed antipsychotic medications, despite evidence of their long-term negative effects and lack of effectiveness for this particular condition.
Another example of racial bias in healthcare is the underrepresentation of racial and ethnic minorities in the medical field. A 2019 study found that the enrolment rates of Black, Hispanic, and Native American medical students lagged behind those of their white counterparts. This disparity contributes to the lack of diversity in the healthcare profession, perpetuating racial bias and affecting the quality of care provided to patients from marginalized communities.
To address racial bias in hospitals and the healthcare system, it is essential to recognize and acknowledge the existence of these biases. Standardizing care procedures and practices can help ensure that all patients receive equitable treatment. Additionally, healthcare professionals should actively work to identify and address their biases through training, education, and collaboration with individuals from historically marginalized groups. By fostering a culture of inclusivity and continuous learning, hospitals can strive to provide culturally competent care that meets the needs of all patients, regardless of their racial or ethnic background.

Gender bias
A survey conducted in early 2019 found that a higher proportion of women than men believe gender discrimination in patient care is a serious problem. The survey also revealed that one in five women felt that their symptoms had been ignored or dismissed due to their gender, and 17% reported being treated differently because of their gender. These perceptions are supported by studies showing that women who present with the same condition as men may not receive the same evidence-based care.
One example of gender bias in healthcare is the historical diagnosis of "hysteria," which was initially used for both men and women but eventually became predominantly associated with women exhibiting symptoms of premenstrual tension, anxiety, or post-traumatic stress disorder (PTSD). This label often led to women's symptoms being dismissed or not taken seriously.
Another manifestation of gender bias is the underestimation of women's pain. Gender stereotypes influence how healthcare professionals interpret and respond to female pain. Female patients' pain is often viewed as a result of amplified emotionality, psychological vulnerability, or dramatization, leading to a tendency to interpret their symptoms as psychosomatic rather than organic. As a result, women are less likely to be prescribed analgesics and opiates and are more likely to be referred to psychotherapy instead of receiving pharmacological treatments.
To address gender bias in healthcare, it is crucial to increase awareness among healthcare professionals. This can be achieved through training opportunities, practice coaches, and education on patient experience and communication. Additionally, encouraging discussions about gender bias during team meetings and asking open-ended questions can help identify and mitigate biased attitudes and behaviors.
Furthermore, addressing gender bias in medical education is essential. Curricula should include content related to gender bias, especially in pain management, to ensure that future clinicians are equipped with the knowledge and skills to provide equitable care to all patients, regardless of gender.

Age bias
Older patients are often viewed as a homogeneous group, and this assumption can lead to inappropriate care. When an older person enters a hospital, they are often treated as more dependent than they are, and this attitude can cause a regression in their behaviour. This can be seen in the example of hospital staff quickly putting a diaper on an older person who did not need one before, simply because it is faster and more convenient for the staff.
Another form of ageism is evident in diagnostic procedures and treatment recommendations. A study in England found that older lung cancer patients were less likely to be referred for surgery, despite age having no impact on postoperative recovery. Similarly, in a study on women with breast cancer, only 7% of physicians conducted routine breast examinations, even though most cases were found in older women.
The tendency to view older adults as "other" can also lead to biased attitudes and practices. Healthcare professionals may only see and treat the most frail, sick, and senile older people, which can evoke death anxiety and contribute to ageist attitudes. This can result in cognitive decline, more hospital stays, disability, worse health, and a lower quality of life for older patients.
To address age bias in hospitals, it is essential to implement strategies that target both individual and systemic biases. High-quality training in cultural competency and medical bias can help improve awareness and understanding of age-related biases. Healthcare professionals should also be encouraged to work with people from historically marginalized groups and seek education on health disparities to overcome their biases and provide equitable care.

Bias against people with disabilities
Hospitals and healthcare professionals can exhibit various forms of bias, including racial bias, gender bias, weight bias, age bias, and bias against people with disabilities. While bias can be explicit, it is often implicit or unconscious, with individuals unaware of their negative evaluations or associations toward certain groups. This can lead to unequal treatment and worse outcomes for marginalised communities.
Secondly, there is a significant bias within the medical community itself. A 2020 study revealed that 83.6% of healthcare professionals implicitly preferred individuals without disabilities. This bias influences their perceptions of people with disabilities, leading them to assume a lower quality of life or perpetual unwellness due to their disabilities. As a result, people with disabilities may receive lower-quality care than they deserve. This bias is often rooted in a lack of understanding of the lived experiences of disabled individuals and the dehumanisation of patients, reducing them to medical models rather than seeing them as whole persons.
Furthermore, during medical emergencies or pandemics, ableism becomes more pronounced. Decisions about rationing care or resources often prioritise those considered "most useful to society," pushing individuals with disabilities to the periphery. This "survival of the fittest" mentality further marginalises an already vulnerable community, perpetuating a long history of discrimination and bias in healthcare access. The COVID-19 pandemic highlighted this issue, with organisations, medical institutions, and governments making statements that implied only the sick, elderly, and disabled would succumb to the virus, reinforcing ableist attitudes.
To address bias against people with disabilities in hospitals, it is essential to acknowledge the problem and actively work towards change. Healthcare professionals should undergo bias training to recognise their implicit biases and understand how these biases influence their clinical decisions and patient interactions. Additionally, partnering with patients and creating a sense of teamwork can help foster empathy and challenge discriminatory attitudes. By prioritising the identification and elimination of bias, hospitals can strive to provide equitable care for all patients, regardless of their abilities.

Bias against the LGBTQ+ community
Hospitals and healthcare professionals ideally should provide equitable care to all patients, regardless of their identity or background. However, biases and prejudices held by healthcare providers can lead to differential treatment and negative health outcomes for certain groups.
Lesbian, Gay, Bisexual, Transgender, Queer, and other sexual and gender minority (LGBTQ+) individuals often experience discrimination and bias in healthcare settings. This can manifest in various ways, including explicit discrimination, such as misgendering, as well as more subtle forms of bias. For example, a transgender patient described an experience where a healthcare provider refused to acknowledge their girlfriend, referring to her as their "boyfriend", and made them extremely uncomfortable. In another tragic case, a transgender teenager admitted to a hospital for suicidal ideation and self-harm was repeatedly misgendered and discharged early by hospital staff. This individual later committed suicide.
Discrimination and bias against the LGBTQ+ community in healthcare settings can have severe consequences, including delays or denials of medically necessary care. For instance, a patient with HIV was refused medication by hospital staff after disclosing that he had sex with men. Additionally, LGBTQ+ parents may also face discrimination, as in the case of an infant with same-sex parents who was turned away from a pediatrician's office.
These experiences of bias and discrimination can deter LGBTQ+ individuals from seeking medical care, which can negatively impact their health and well-being. Furthermore, finding alternative healthcare providers may not always be a feasible option due to limited accessibility and geographic barriers.
To address these issues, it is essential to increase awareness of implicit biases among healthcare professionals and provide training to reduce LGBTQ-related biases. Educational programs and interventions have been shown to be effective in increasing knowledge about the LGBTQ+ community, improving comfort levels in providing LGBTQ-relevant healthcare, and promoting more tolerant attitudes. By addressing biases and discrimination in healthcare, we can strive to ensure equitable and inclusive care for all patients, regardless of their sexual orientation or gender identity.

Frequently asked questions
Bias in a hospital context refers to preconceived notions and prejudices that healthcare professionals may hold towards patients based on various attributes such as race, ethnicity, gender, age, socioeconomic status, or disability. These biases can be implicit, meaning the person is unaware of them, or explicit, where there is an awareness of the evaluation taking place.
Biases can affect clinical judgment, leading to misdiagnosis, inappropriate treatment, or delayed treatment. For example, the underestimation of pain in certain demographic groups can result in inadequate pain management. Biases can also erode trust between healthcare providers and patients, which is crucial for effective care and treatment adherence.
Biases can stem from a lack of familiarity with and understanding of different cultural, social, and economic perspectives. Institutional policies and practices, educational gaps, and a lack of diversity among healthcare professionals can perpetuate these biases. Individual healthcare professionals may also hold implicit biases that influence their behaviors and judgments.
Hospitals can address bias by creating an environment that prioritizes diversity, equity, and inclusion, not just as ideals but as active practices. This includes implementing cultural competency training, promoting diversity initiatives, and revising policies to actively counteract bias. High-quality training in cultural competency and medical bias for healthcare professionals can improve awareness and understanding of diverse cultural experiences, enhance communication skills, and promote reflective practices to recognize and mitigate biases.
