Community Health Nursing Overview

Foundations and Core Terminology of Community Health Nursing

Community health nursing represents a broad and general specialty area within the discipline of nursing. It serves as an umbrella term encompassing subspecialties such as public health nursing, school nursing, occupational health nursing, and developing areas of practice including home health, hospice care, and independent nurse practice.

Within this specialty, a community is defined as a group of people sharing common characteristics or interests who live together within a specific territory or geographical boundary. Health is defined as a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity. It also refers to being free from illness or injury, maintaining fitness, healthiness, good condition, good shape, and fine fettle, and represents the place where individuals are found under usual conditions. Nursing is defined as assisting sick individuals to become healthy and aiding healthy individuals to achieve optimum wellness. Community health is part of the medical and paramedical approach concerned with the health of the entire population.

As a foundation of the nursing profession, community health nursing is defined by Ruth B. Freeman as a service rendered by a professional nurse with communities, groups, families, and individuals at home, in health centers, in clinics, in schools, and in workplaces for the promotion of health, prevention of illness, care of the sick at home, and rehabilitation. The ultimate goal of community health nursing is to raise the level of health of the citizenry.

Public Health Frameworks and Practice Models

Public health is defined by Winslow as the science and art of promoting health, preventing disease, and prolonging life, to enable every citizen to realize his birthright to health and longevity. The World Health Organization defines public health as the art of applying science in the context of politics so as to reduce inequalities in health, aiming for the best health for the greatest number of people.

Public health nursing refers to community health nursing practiced specifically within the public sector. According to the World Health Organization Expert Committee on Nursing (WHOECN), public health nursing is a special field of nursing that combines the skills of nursing, public health, and certain phases of social assistance, functioning as a part of total public health. The National League for Nursing (NLGN) defines public health nursing as the practice of nursing in local or national health departments and public schools.

Community-based nursing involves applying the nursing process when caring for individuals, families, and groups in settings where they live, work, attend school, or move through the health care system. Population-focused nursing concentrates on specific groups of people and focuses primarily on health promotion and disease prevention regardless of geographical location, as described by Baldwin et al. (1998).

Population-focused practice exhibits five key characteristics:

  1. It focuses on the entire population.
  2. It is based on an assessment of the population's health status.
  3. It considers the broad determinants of health.
  4. It emphasizes all levels of prevention.
  5. It intervenes with communities, systems, individuals, and families.

The ultimate goal of population-focused practice is to promote healthy communities.

Community Health Assessment Data and Interventions

A scientific approach to population health relies on two key types of data: the epidemiology or body of knowledge regarding a specific health problem and its solution, and detailed information about the community itself.

Data types and their corresponding sources include:

  • Demographic Data: Sourced from vital statistics and census records.
  • High-Risk Group Data: Sourced from health statistics and disease statistics.
  • Available Services and Providers: Sourced from city directories, phone books, local or regional social workers, lists of low-income service providers, and community health nurses.

The Intervention Wheel serves as a model for practice and consists of three elements: it is population-based, operates across three levels of practice (community, system, and individual or family), and incorporates 17 public health interventions.

The 17 public health interventions are:

  1. Surveillance
  2. Disease and other health event investigation
  3. Outreach
  4. Screening
  5. Case finding
  6. Referral and follow-up
  7. Case management
  8. Delegated functions
  9. Health teaching
  10. Counseling
  11. Consultation
  12. Collaboration
  13. Coalition building
  14. Community organizing
  15. Advocacy
  16. Social marketing
  17. Policy development and enforcement

Determinants of Health and Scope of Organized Public Health

Health outcomes are shaped by ten primary determinants of health:

  1. Income and social status
  2. Education
  3. Physical environment
  4. Employment and working conditions
  5. Social support networks
  6. Culture
  7. Genetics
  8. Personal behavior and coping skills
  9. Health services
  10. Gender

Public health and community health encompass the science and art of preventing disease, prolonging life, and promoting health and efficiency through organized community efforts aimed at:

  • Sanitation of the environment.
  • Control of communicable infections.
  • Education of the individual in personal hygiene.
  • Organization of medical and nursing services for early diagnosis and preventive treatment of disease.
  • Development of social machinery to ensure everyone a standard of living adequate for the maintenance of health.

Health Promotion and Levels of Prevention

Health promotion consists of activities that enhance resources directed at improving overall well-being. Disease prevention consists of activities that protect people from disease and the adverse effects of disease.

Leavell and Clark's Three Levels of Prevention divide preventive practice into three distinct stages:

  1. Primary Prevention: Refers to activities directed at preventing a problem before it occurs by altering susceptibility or reducing exposure for susceptible individuals.
  2. Secondary Prevention: Involves early detection and prompt intervention during the period of early disease pathogenesis.
  3. Tertiary Prevention: Targets populations that have experienced disease or injury, focusing on the limitation of disability and implementation of rehabilitation.

Core Principles, Philosophy, and Concepts of Community Health Nursing

Community health nursing operates under basic principles that dictate structural delivery and client interaction:

  • The community is the primary client, while the family serves as the fundamental unit of care. Care is provided across four levels of clientele: individual, family, sub-groups or population aggregates, and the community.
  • The client is considered an active partner rather than a passive recipient of care. The philosophical foundation of community health nursing, as defined by Dr. Shetland, is based on the worth and dignity of man.
  • Practice is continually influenced by ongoing changes in the public health system, including shifts in demographic and epidemiologic disease trends, new technologies, existing and emerging environmental hazards, and health reforms.

The mission of community health nursing comprises five essential elements:

  1. Health Promotion
  2. Health Protection
  3. Health Balance
  4. Disease Prevention
  5. Social Justice

The fundamental concepts of community health nursing dictate that its primary focus is health promotion, community health workers act as generalists, service is long-term or lifetime in nature, the knowledge base is comprehensive, and clinical actions are guided systematically by the nursing process.

Essential Features of Community and Public Health Nursing

Community and Public Health Nursing (CPHN) possesses eight defining features and characteristics:

  1. Developmental: Creates ongoing opportunities for client education and developmental progress.
  2. Multidisciplinary: Addresses varied health needs through interprofessional approaches.
  3. Ecology-Oriented: Grounded in the community setting and centered around the natural environment.
  4. Promotes Social Justice: Protects the health interests of all community members by advocating for equal health access.
  5. Values Consumer Involvement: Treats clients as equal partners in health care management.
  6. Uses Prepayment Mechanisms: Operates through tax-based budgeting systems.
  7. Focuses on Preventive Services: Prioritizes disease prevention and health promotion over curative care.
  8. Offers Comprehensive Care: Provides continuous health care services across the full human lifespan, described as care from womb to tomb.
