Social determinants of health (SDOH) include nonmedical social structures, policies, and economic systems that affect health and quality-of-life outcomes
Public health science brings together environmental science, epidemiology, biostatistics, biomedical sciences, and social and behavioral sciences
Understanding negative and positive factors from both a population and individual perspective helps develop nursing interventions that incorporate the full continuum of health
Public health is the science and art of preventing disease, prolonging life, and promoting health and efficiency through organized community effort
3 core functions of public health:
Assessment focuses on the systematic collection, analysis, and monitoring of health problems and needs
Policy development uses scientific knowledge to develop comprehensive public health policies
Assurance assures constituents that public health agencies provide services necessary to achieve agreed-upon goals
Globalization leads to increased disparities between rich and poor, environmental degradation, and food security issues
Key population health measure is life expectancy, defined as the average number of years a person born in a given country would live if the mortality rate by age remained constant in the future
Upstream determinants of health include social relations, neighborhoods, communities, institutions, and social and economic policies
Cultural competency is essential for health-care providers to provide quality care to culturally diverse populations
Cultural humility is an ongoing understanding that we must approach others as equals, with respect for their prevailing beliefs and cultural norms
Communities with fewer resources and inadequate infrastructure are at greater risk for disease
Environment is a key factor contributing to morbidity and mortality, with poor sanitation and lack of potable water increasing the spread of communicable diseases
Public health nursing focuses on promoting and protecting the health of populations using knowledge from nursing, social, and public health sciences
Public health nursing roles include coordination, consultation, leadership, advocacy, health education, health promotion, regulatory activities, ongoing education, practice evaluation, professional relationships, and collaboration
Public health ethics include principles of autonomy, dignity, and rights of individuals, as well as the concept of social justice
Global health:
Collaborative transnational research and action for promoting health for all
WHO classic definition of health: "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity"
Countries differentiated based on country-level income data: high-income countries (HICs), upper-middle-income countries (UMICs), lower-middle-income countries (LMICs), and low-income countries (LICs)
Growing disparity between lower groups (LICs and LMICs) and higher groups (HICs and UMICs)
Public health organizations and management: global to local:
WHO's primary role is to direct and coordinate international health within the United Nations' system
WHO's areas of work include health systems, promoting health through the life course, NCD, CD, and corporate services
WHO expanded to include emergency response and disaster preparedness initiatives
Institution of International Health Regulations (IHRs) for disease outbreaks response
IHRs increase WHO's ability to respond to public health emergencies
Seventeen current SDGs with a target date of 2030 built on the MDGs that ended in 2015
Purpose of SDGs: "end poverty, protect the planet, and ensure prosperity for all"
National health organizations:
Individual countries have their own national organizations dedicated to health promotion and protection
Coordinate with the WHO and work together to address threats to health
Provide infrastructure and oversight of population health
U.S. Constitution provides a two-layer public health system at federal and state levels
States required to provide protections to citizens after ratification of the 14th Amendment
Centers for Disease Control and Prevention (CDC):
Mission: "protect America from health, safety, and security threats both foreign and in the U.S."
Scope includes prevention and control of CDs and NCDs, injuries, workplace hazards, disabilities, and environmental health threats
Conducts research, maintains national surveillance system, and responds to health emergencies
Collaborates with state and local health departments for disease and injury surveillance
Sets standards for disease prevention strategies and provides funding for public health surveillance and programming
State public health departments:
Independently decide on structure of local and state health departments
Variations exist across states in organization and management of public health systems
Basic mandate is to protect the health of citizens in their jurisdiction
Local public health departments:
Mandate to protect the health of citizens in their area
Perform activities like surveillance, outbreak investigation, quarantine, and reporting diseases to state health departments and the CDC
Help federal government track disease incidence and prevalence nationally
Summary points:
Public health is a core component of nursing knowledge and competency
Nursing goal is to help people achieve optimal health by understanding health of populations and communities
Public health science aims to improve health from cellular to global level
Public health builds a healthy environment and responds to health threats
Public health nursing is a recognized specialty with specific scope and standards of practice
Formal structures exist from global to local levels to promote health and protect populations
Introduction to optimizing population health:
Vision of Healthy People 2030: "a society in which all people achieve their full potential for health and well-being"
Mission: "to promote and evaluate the nation's efforts to improve health and well-being"
Shift from focus on older adults to entire population with emphasis on health equity, SDOH, and well-being
Population health promotion, health protection, and risk reduction:
Social-ecological model of health includes physical and social environments in health promotion
Health promotion enables people to improve their health beyond individual behavior
Risk reduction actions aim to reduce adverse outcomes like using condoms for disease transmission prevention
Health protection increases individual's ability to protect against disease
Health promotion:
Prevention interventions focus on behavioral change for biological and behavioral change at individual level
Ecological determinants of health include potable water, sanitation, climate action, and more
SDOH affect health and quality of life risks and outcomes
Ecological model expands health promotion beyond individual approach
Health protection and risk reduction:
Promotes healthy lifestyle and environment
Interventions protect individuals from disease by reducing risk
Individuals adopt protective health activities
Prevention frameworks:
Health prevention aims to prevent disease, injury, and slow disease progression
Public health policies, programs, and practices improve population health and reduce disease risk
Natural history of disease provides foundation for prevention frameworks
Levels of prevention:
Primary prevention prevents disease development in healthy individuals
Secondary prevention detects and treats disease early to reduce morbidity and mortality
Tertiary prevention aims to prevent disability and premature death
Primary prevention:
Focuses on promoting healthy behaviors and building ability to protect against disease
Includes vaccinations and health education
Secondary prevention:
Involves early detection of problems in asymptomatic individuals with risk factors
Targets conditions not yet clinically apparent for earlier detection
Tertiary prevention:
Focuses on reducing disability, promoting cure, and preventing death in diagnosed individuals
Includes medical, environmental, and psychosocial strategies
Universal, selected, and indicated prevention models:
Useful for preventable diseases with known early signs
Limitations in adapting to diseases with complex risk factors
Includes clinical, behavioral, and environmental interventions
Model divides the continuum of care into three parts: prevention, treatment, and maintenance
Under prevention, there are three categories: universal, selected, and indicated
Universal prevention intervention is applicable to the whole population and is not based on individual risk
Strives to deter the onset of a health issue within the general population
Often the intervention is passive, such as a media campaign
Selective prevention interventions are aimed at a subset of the population that has an increased level of risk for developing disease
Based on demographic variables such as age, gender, or race, or on genetic, environmental, or socioeconomic risk factors
