👨‍⚕️Nursing Care of Vulnerable Populations Unit 5 – Racial and Ethnic Health Disparities

Key Concepts and Definitions

• Health disparities refer to preventable differences in the burden of disease, injury, violence, or opportunities to achieve optimal health experienced by socially disadvantaged racial, ethnic, and other population groups and communities
• Health equity is the attainment of the highest level of health for all people, requiring valuing everyone equally with focused and ongoing societal efforts to address avoidable inequalities, historical and contemporary injustices, and the elimination of health and healthcare disparities
• Social determinants of health are the conditions in the environments where people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning, and quality-of-life outcomes and risks
  • Includes factors such as socioeconomic status, education, neighborhood and physical environment, employment, and social support networks, as well as access to healthcare
• Racial and ethnic minorities often experience worse health outcomes compared to the majority white population due to a complex interplay of social, economic, and environmental factors
• Health inequities are rooted in historical and contemporary injustices and discrimination that have systematically disadvantaged certain groups

Historical Context of Health Disparities

• Racial and ethnic health disparities in the United States have deep historical roots dating back to the colonial era and the enslavement of African Americans
• Segregation, discrimination, and racism in healthcare settings persisted long after the Civil War and the abolition of slavery
  • Examples include the Tuskegee Syphilis Study (1932-1972) and the forced sterilization of women of color and those with disabilities
• The Civil Rights Movement of the 1950s and 1960s brought attention to racial injustices and led to legislation aimed at reducing discrimination and improving access to healthcare for minority populations
  • The passage of Medicare and Medicaid in 1965 helped increase access to healthcare for low-income and elderly populations, which included a disproportionate number of racial and ethnic minorities
• Despite progress, the legacy of historical injustices and ongoing structural racism continues to contribute to health disparities experienced by racial and ethnic minority groups today

Social Determinants of Health

• Social determinants of health are the conditions in which people are born, grow, live, work, and age that shape health outcomes
• Economic stability, including factors such as income, employment, and housing, can significantly impact health by influencing access to healthcare, healthy food, and safe living environments
• Education access and quality are strongly linked to health outcomes, with higher levels of education associated with better health and longer life expectancy
• Healthcare access and quality, including the availability of affordable, culturally competent care and insurance coverage, play a crucial role in health outcomes
  • Racial and ethnic minorities often face barriers to accessing quality healthcare due to factors such as lack of insurance, language barriers, and provider bias
• Neighborhood and built environment, including access to safe housing, transportation, and green spaces, can impact health by influencing exposure to environmental hazards and opportunities for physical activity and social interaction
• Social and community context, including discrimination, social cohesion, and civic participation, can affect mental and physical health outcomes

Specific Health Disparities Among Racial and Ethnic Groups

• African Americans experience higher rates of chronic diseases such as hypertension, diabetes, and obesity compared to non-Hispanic whites
  • African American women have a 41% higher breast cancer death rate despite a lower incidence rate
• Hispanic/Latino populations have higher rates of obesity and diabetes compared to non-Hispanic whites
  • Hispanics are also less likely to have health insurance and access to preventive care
• American Indians and Alaska Natives have higher rates of diabetes, cardiovascular disease, and substance abuse disorders compared to the general U.S. population
  • They also experience significant disparities in life expectancy and infant mortality
• Asian Americans, while often perceived as a "model minority," experience disparities in certain health conditions such as liver cancer and tuberculosis
  • There are also significant variations in health outcomes among different Asian subgroups (Chinese, Filipino, Vietnamese, etc.)
• Native Hawaiians and Pacific Islanders have higher rates of obesity, diabetes, and cardiovascular disease compared to the general U.S. population
  • They also face challenges in accessing culturally competent healthcare services

Causes and Contributing Factors

• Socioeconomic factors, such as poverty, low educational attainment, and lack of access to healthcare, contribute to health disparities by limiting opportunities for healthy living and disease prevention
• Structural racism, including discriminatory policies and practices in housing, education, and employment, creates and perpetuates inequalities that lead to health disparities
• Implicit bias among healthcare providers can lead to unequal treatment and poorer quality of care for racial and ethnic minority patients
  • Studies have shown that providers may underestimate pain in African American patients or provide less effective treatment for conditions such as cardiovascular disease
• Language and cultural barriers can impede effective communication between patients and providers, leading to misunderstandings, lower patient satisfaction, and poorer health outcomes
• Lack of diversity in the healthcare workforce can contribute to cultural misunderstandings and a lack of trust between minority patients and the healthcare system
• Environmental factors, such as air and water pollution, disproportionately affect low-income and minority communities, leading to higher rates of respiratory illnesses, cancer, and other health problems

Impact on Healthcare Delivery and Outcomes

• Racial and ethnic health disparities lead to increased morbidity and mortality among affected populations
  • African Americans have a lower life expectancy than non-Hispanic whites, and Native Americans have a life expectancy 5.5 years lower than the general U.S. population
• Disparities in access to preventive care and early detection lead to more advanced disease at diagnosis and poorer treatment outcomes
  • Hispanic women are more likely to be diagnosed with late-stage cervical cancer compared to non-Hispanic white women
• Unequal treatment and lower quality of care contribute to worse health outcomes for racial and ethnic minorities
  • African American patients with heart failure are less likely to receive evidence-based treatments and have higher readmission rates compared to white patients
• Health disparities result in increased healthcare costs due to the higher burden of chronic disease, preventable hospitalizations, and the need for more intensive treatment
  • Estimates suggest that eliminating health disparities could reduce direct medical care expenditures by $229.4 billion and indirect costs associated with illness and premature death by over$1 trillion
• Disparities in maternal and infant health outcomes, such as higher rates of preterm birth and maternal mortality among African American women, highlight the intergenerational impact of health inequities

Strategies for Addressing Disparities

• Increasing diversity in the healthcare workforce can improve cultural competence, communication, and trust between patients and providers
  • Pipeline programs and initiatives to support underrepresented minority students in pursuing healthcare careers are essential
• Implementing culturally and linguistically appropriate services, such as language interpretation and culturally tailored health education materials, can improve patient engagement and outcomes
• Addressing social determinants of health through multi-sectoral partnerships and community-based interventions
  • Examples include investing in affordable housing, improving access to healthy food, and promoting early childhood education
• Collecting and analyzing race, ethnicity, and language data to identify disparities, monitor progress, and inform targeted interventions
• Providing implicit bias training for healthcare professionals to raise awareness and reduce disparities in care
• Advocating for policies that promote health equity, such as expanding access to healthcare coverage, addressing environmental injustices, and investing in public health infrastructure
• Engaging communities in the design and implementation of health equity initiatives to ensure that interventions are responsive to local needs and priorities

Nursing's Role in Promoting Health Equity

• Nurses play a critical role in advancing health equity through direct patient care, advocacy, education, and research
• Providing patient-centered, culturally competent care that respects the unique needs and preferences of diverse patient populations
  • This includes understanding and addressing the social, cultural, and linguistic factors that influence health beliefs and behaviors
• Advocating for policies and practices that promote health equity within healthcare organizations and the broader community
  • Nurses can serve on diversity, equity, and inclusion committees, participate in community health needs assessments, and engage in policy advocacy at the local, state, and national levels
• Educating patients, families, and communities about health disparities and empowering them to take an active role in their health and healthcare decision-making
  • This includes providing culturally tailored health education and promoting health literacy
• Conducting research to identify and address health disparities, and translating research findings into evidence-based practice
  • Nurses can participate in community-based participatory research, which engages communities as equal partners in the research process
• Promoting a diverse and inclusive nursing workforce through mentorship, leadership development, and support for underrepresented minority nurses
  • This includes creating a supportive and inclusive work environment that values diversity and promotes cultural competence
• Collaborating with interprofessional teams and community partners to address the complex social, economic, and environmental factors that contribute to health disparities
  • Nurses can work with social workers, community health workers, and other professionals to provide comprehensive, coordinated care that addresses the holistic needs of patients and families
