Vulnerable Populations Unit Notes

Introduction

  • This unit focuses on the challenges faced by vulnerable populations including LGBT families, teenage parents, and health disparities among special groups of adults as outlined in Varcarolis Chapters 5, 21, 22, 23, 24, 25, and ATI Community Health Nursing Chapters 1, 2, 7.

Objectives

    • Migrant workers
    • Immigrant and minority populations
    • Rural communities
    • Mental illness
    • Teen parents
    • LGBTQ+ individuals
    • Veterans
    • Homeless individuals
  • 5.06 Identify the relationship between poverty, health insurance, homelessness, and health outcomes.

  • 5.08 Apply the nursing process to the care of vulnerable populations.

Unit Focus

  • Examining how health disparities affect vulnerable populations.
  • Investigating the impact of poverty on health.
  • Identifying characteristics of different vulnerable populations.
  • Recognizing key issues among these populations.
  • Understanding assessment and nursing care elements for vulnerable individuals.

Health Equity & Vulnerable Populations

Definitions

  • Health Equity: "Everyone has a fair and just opportunity to be healthier."
  • Goal: Eliminate health disparities and achieve health literacy to improve health and well-being for all.
    • Impacted groups include:
    • African Americans
    • Native Americans
    • Sexual minorities
    • People with disabilities
    • Veterans
    • Those incarcerated
    • Individuals in rural areas

Factors Impacting Health

  1. Income and social status: Higher status often leads to better health.
  2. Education: Higher education correlates with improved health.
  3. Physical Environment: Safe housing and neighborhoods contribute to health.
  4. Social Support Networks: Strong connections can mitigate adverse health effects.
  5. Health Services: Access to quality health care impacts health outcomes.
  6. Personal Behavior and Coping Skills: Lifestyle choices affect health resilience.
  7. Genetics: Biological factors can predispose individuals to health conditions.

Social Determinants of Health (SDOH)

  • Comprised of five domains:
    1. Economic stability
    2. Education access and quality
    3. Health care access and quality
    4. Neighborhood and built environment
    5. Social and community context
  • Examples of influence:
    • Safe housing and neighborhoods
    • Access to food and health care
    • Discrimination and violence affect mental health and access to resources.

Definitions of Key Concepts

  1. Vulnerability: Susceptibility to stressors in the context of health.
  2. Risk: Increased probability of illness or adverse events.
  3. Resilience: Ability to resist or manage effects of vulnerability.
  4. Human Capital: Knowledge, skills, and strengths contributing to health.
  5. Health Disparities: Differences preventing populations from achieving optimal health.
  6. Cumulative Risks: Accumulation of risk factors that compound vulnerability.

Vulnerable Populations

  • Defined as underserved and disadvantaged groups facing higher risks of negative health outcomes due to:
    • Fewer resources
    • Low human capital, which restricts options for care
    • Experiences of powerlessness, victimization, and disenfranchisement.
  • Key issues:
    • Low access to health care
    • Increased mental health issues
    • Higher exposure to violence and adverse social conditions.

Specific Issues by Population

  • Underinsured: Limited access to necessary health services.
  • Teen Parents: High-risk pregnancies and social stigmas.
  • LGBTQ+ Individuals: Experience of discrimination leads to mental health challenges and unmet health needs.
  • Veterans: High risks for PTSD and homelessness post-service.
  • Migrant Workers: Face unique health service access issues due to mobility and employment instability.

Economics of U.S. Health Care Delivery

Economic Challenges

  • The U.S. spends significantly on health care with:
    • 97% going to individual health care
    • 3% for population-level health care.
  • Economic disparities contribute to differences in mortality and morbidity rates.

Medicare & Medicaid Overview

  • Medicare: Health care for individuals 65+ or with certain disabilities.
    • Part A: Inpatient care; at no premium after 10 years of work.
    • Part B: Outpatient care and physician services; participants pay premiums.
    • Part D: Prescription drug coverage, with exclusions.
  • Medicaid: Joint federal-state program for low-income individuals, covering various health services but less access to mental health care.

Financing Models in Health Care

  • Retrospective Reimbursement: Payment after care is delivered.
  • Prospective Reimbursement: Pre-established amounts paid prior to service delivery.
  • Capitation: Providers paid per enrolled patient, often limiting services.

Specific Health Concerns for Vulnerable Populations

  • Poverty: Leads to health issues like chronic diseases, malnutrition, and limited access to care.
  • Homelessness: Increased exposure to acute and chronic illness, higher risks for communicable diseases, and mental health challenges.
    • In January 2020, over 580,000 individuals experienced homelessness in the U.S.

Barriers to Health Care Access

  1. Lack of providers in rural areas.
  2. High rates of uninsured individuals, particularly among young adults and minorities.
  3. Cultural and linguistic barriers hindering effective communication and treatment accessibility.

Conclusion

  • Interventions must focus on creating trusting environments and understanding socioeconomic contexts to improve health outcomes for vulnerable populations. Community health nursing must integrate these considerations into care planning and delivery to empower these communities.
