Public Health Nursing Theory and Practice NURS 6710 Study Notes
NURS 6710 – Public Health Nursing Theory and Practice
Detailed Study Notes (Walden University, 5 credits)
These notes are organized directly around the official Walden University course description. They synthesize the core content for advanced public health nursing (PHN) practice at the graduate level. The course builds on NURS 6700 (Epidemiology and Population Health) and leads into NURS 6720 (Population-Based Interventions).
Public health nursing is shaped by social, behavioral, cultural, and demographic factors that impact health care at multiple levels (individual, family, community, population, and systems). The course emphasizes:
History of public health and public health nursing
Public health law and ethics
System infrastructure
Health equity and health disparities
Theories and research on social determinants of health (SDOH)
Models to assess and deliver population-centered care
Promoting a culture of health
Recommended primary text (commonly used in this course): Stanhope, M., & Lancaster, J. Public Health Nursing: Population-Centered Health Care in the Community (10th or 11th ed., Elsevier). It aligns closely with the course structure (Parts 1–4 cover influencing factors, delivery forces, conceptual frameworks, and community interventions).
Supplemental resources:
Quad Council Coalition (QCC) Community/Public Health Nursing Competencies (2018) – 8 domains, 3 tiers (Tier 1 generalist, Tier 2 supervisory, Tier 3 leadership).
Healthy People 2030, WHO SDOH framework, ANA Public Health Nursing: Scope and Standards of Practice.
1. History of Public Health and Public Health Nursing
Key Timeline and Milestones (focus on U.S. context with global influences):
Ancient roots: Sanitation, quarantine (e.g., Biblical laws, Roman aqueducts).
1800s: Industrial Revolution → urban crowding, cholera, tuberculosis. Florence Nightingale (Crimean War, 1850s) – environmental theory, statistical data, founder of modern nursing.
Late 1800s–early 1900s: Lillian Wald (Henry Street Settlement, 1893, New York) – coined “public health nursing,” focused on social reform, home visiting, and immigrants.
1900s milestones:
1912: National Organization for Public Health Nursing.
1920s–1930s: Sheppard-Towner Act (1921) – federal maternal/child health funding.
1940s–1950s: Post-WWII, Hill-Burton Act (hospital construction).
1960s–1970s: Civil Rights era, Medicare/Medicaid, community mental health.
1980s–1990s: HIV/AIDS crisis, IOM reports (The Future of Public Health, 1988).
2000s–present: Healthy People initiatives (1980–2030), post-9/11 preparedness, Affordable Care Act (2010), COVID-19 response (2020s).
Evolution of PHN Role: From individual/family-focused home visiting → population-centered, systems-level practice emphasizing prevention, equity, and policy.
Core Functions of Public Health (IOM 1988, updated in Public Health 3.0):
Assessment – monitor health status, diagnose problems.
Policy Development – inform, mobilize, develop policies.
Assurance – enforce laws, assure competent workforce, evaluate services.
10 Essential Public Health Services (CDC, revised 2020) – framework for infrastructure.
2. Public Health Law and Ethics
Public Health Law:
Police powers – state authority to protect public health/safety (e.g., quarantine, vaccination mandates).
Landmark cases: Jacobson v. Massachusetts (1905) – upheld compulsory vaccination.
Federal vs. state roles; preemption; emergency powers (e.g., Stafford Act, Public Health Service Act).
Key laws: HIPAA (privacy), ACA (prevention), Title VI (civil rights in health).
Ethics in PHN:
Principles: Autonomy, beneficence, non-maleficence, justice, veracity, fidelity.
ANA Code of Ethics (2015, Provision 8) – public health advocacy.
PHN-specific: Population focus creates tension with individual rights (e.g., mandatory reporting, contact tracing).
Ethical dilemmas: Resource allocation during disasters, vaccine hesitancy, environmental justice.
Frameworks: Public Health Code of Ethics (APHA, 2019 revision); principles of social justice and human rights.
Application: Use ethical decision-making models (e.g., 4A’s: Ask, Analyze, Act, Assess) when balancing individual rights vs. collective good.
3. Public Health System Infrastructure
Levels of the U.S. Public Health System:
Federal: CDC, HHS, HRSA, EPA, FDA.
State: State health departments (vary by structure).
Local: County/city health departments (core service providers).
Global: WHO, UNICEF, NGOs.
Key Components:
Workforce (PHNs, epidemiologists, environmental health specialists).
Data systems (e.g., National Notifiable Diseases Surveillance System).
Laboratories, emergency preparedness (Strategic National Stockpile).
Funding: Block grants, categorical funding, public-private partnerships.
Public Health 3.0 (2016): Cross-sector collaboration, data-driven, equity-focused, accountable.
Quad Council Competencies Integration (8 Domains – apply across Tiers 1–3):
Assessment & Analytic Skills
Policy Development/Program Planning Skills
Communication Skills
Cultural Competency Skills
Community Dimensions of Practice Skills
Public Health Sciences Skills
Financial Planning & Management Skills
Leadership & Systems Thinking Skills
4. Health Equity and Health Disparities
Definitions (Healthy People 2030):
Health disparity: Preventable difference in health outcomes between groups (e.g., by race, income, geography).
Health equity: Attainment of highest level of health for all; requires removing obstacles (poverty, discrimination).
Examples: Higher maternal mortality in Black women; rural vs. urban access; LGBTQ+ disparities in mental health.
Measurement:
Healthy People 2030 objectives (leading health indicators).
Indices: Social Vulnerability Index (CDC), Area Deprivation Index.
Strategies to Reduce Disparities: Culturally/linguistically appropriate services (CLAS standards), community-based participatory research (CBPR), policy advocacy.
5. Social Determinants of Health (SDOH)
WHO Framework & Healthy People 2030 Domains (5 key areas):
Economic Stability (employment, income, food/housing security)
Education Access & Quality
Healthcare Access & Quality
Neighborhood & Built Environment
Social & Community Context
Upstream vs. Downstream: Focus on upstream (policy, systems) interventions rather than just downstream (individual behavior).
Theories Linking SDOH to PHN:
Ecological Model (McLeroy et al.): Intrapersonal, interpersonal, institutional, community, policy levels.
Social-Ecological Model (CDC).
Research Application: Analyze studies showing SDOH explain ~80% of health outcomes (vs. clinical care ~20%). Use data to advocate (e.g., zip code better predictor than genetic code).
6. Theories and Research in Public Health Nursing
Key Theories/Models (Part 3 of Stanhope text):
Nursing Theories: Nightingale’s Environmental Theory; Orem’s Self-Care; Roy’s Adaptation.
Public Health Theories:
Health Promotion Models: Pender’s Health Promotion Model; Health Belief Model; Transtheoretical (Stages of Change).
Community Models: Community as Partner (Anderson & McFarlane) – assessment wheel (people, place, etc.).
Intervention Wheel (Keller & Strohschein): 17 interventions at individual/family/community levels (e.g., surveillance, advocacy, coalition building).
Implementation Science: RE-AIM, PRECEDE-PROCEED model for program planning.
Evidence-Based Practice (EBP): Integrate best research, clinical expertise, population preferences.
Research in PHN:
Emphasis on population-level outcomes (not just individual).
Designs: Community trials, quasi-experimental, mixed-methods, CBPR.
Critical appraisal: Levels of evidence (e.g., RCTs for interventions, epidemiological studies for disparities).
7. Models to Assess and Deliver Health Care to Populations
Community Assessment Models:
Windshield Survey (quick observational scan).
Community Health Assessment (CHA) process (Mobilizing for Action through Planning and Partnerships – MAPP).
Asset-Based Community Development (ABCD) vs. deficit-based.
Levels of Prevention (Leavell & Clark):
LevelFocusExamplesPrimaryPrevent disease onsetImmunizations, health educationSecondaryEarly detection & treatmentScreenings (mammograms, BP)TertiaryReduce complicationsRehab, chronic disease management
Delivery Models:
Nurse-managed health centers.
Healthy Cities/Communities movement.
Population health management (Triple Aim → Quintuple Aim: add equity & joy in work).
Intervention Wheel – 17 evidence-based interventions grouped by levels of practice.
Culturally Competent Care: Cultural humility, CLAS standards.
8. Promoting a Culture of Health
Robert Wood Johnson Foundation (RWJF) Culture of Health Framework:
Action areas: Healthier, more equitable communities; cross-sector collaboration; system changes; individual empowerment.
Goal: Everyone in the U.S. lives a healthier life, regardless of background.
PHN Role in Culture of Health: Advocacy, coalition-building, policy influence, evaluation of population outcomes.
Future Directions: Climate change & health, telehealth in rural areas, AI/data analytics, workforce diversity, global health equity.
