Community health nursing is a specialty in which
the unit of care is a specific community or
aggregate, and the nurse has responsibility to
promote group health.
The goal of this specialty is health improvement
of the community. The skills required for
excellence in community health nursing practiceinclude epidemiology, research, teaching,
community organizing, and interpersonal
relational care, as well as many others.

Community-Oriented, Population-
Focused Care
a community is a group ofpeople who havesome characteristics in common, arebounded by time, interact with one another,and feel a connection to one another.
Community orientation is a process that isactivelyshaped by the unique experiences,
knowledge, concerns, values, beliefs, andculture of a given community.

THEORIES AND MODELS FOR COMMUNITY
HEALTH NURSING PRACTICE
A theory is a set of systematicallyinterrelated concepts or hypotheses thatseek to explain or predict phenomena.
These early theories, also termedgrandtheories orconceptual models, provided abasis for building nursing knowledge.
One feature separating nursing theory fromother professional theories is the use of thenursing metaparadigm concepts: nursing,client/patient, health, and environment.

To more fully understand the elementsinherent in a nursing theory, a pictorialrepresentation, or model, is often used.
These models provide a visual means tounderstand the relationships between, forinstance, the nurse and the environment, the
nurse and the client, or the stress factorsexperienced by the client.

Nightingales Theory of
Environment
Florence Nightingales environmental theory hasgreat significance to nursing in general and tocommunity health nursing specifically, because it
focuses on preventive care for populations. Crime WarHer observations suggested that
disease was more prevalent in poor environments,and that health could be promoted by providingadequate ventilation, pure water, quiet, warmth,light, and cleanliness.
The crux of her theory was that poor environmentalconditions are bad for health and that goodenvironmental conditions reduce disease.

Orems Self-Care Model
Dorothy Orem, a nurse administrator andeducator, focused on the concept ofself-carelearned, goal-oriented actions topreserve and promote life, health, and well-being. She described people who neednursing care as those who lack ability in self-
care
7/27/2019 Theoretical Basis Of
10/40
The goal of nursing action is to help peoplerecognize their selfcare demands andlimitations and increase their self-care ability.Nursing care also functions to meet clientsself-care needs until they are able to care forthemselves.
7/27/2019 Theoretical Basis Of
11/40
Orem further described three types of
requirements that influence peoples self-care
abilities:
Universal requirements, common to all human beings,are self-care activities essential to meet physiologicand psychosocial needs.
Developmental requirements are activities necessary
to help people progress developmentally.
Health-deviation requirements are activities neededto help people deal with a diminished level ofwellness.
7/27/2019 Theoretical Basis Of
12/40
Although Orems model focused primarily on individuals, itcan be applied to community health nursing.
Populations and communities can be considered to have acollective set of actions and requirements that affect the
well-being of the total group. If an aggregates demands for self-care exceed its ability,
the aggregate experiences a self-care deficit, andcommunity health nursing intervention is indicated.
According to this interpretation, the goal of community
health nursing is to promote a communitys collectiveindependence and selfcare ability.

Neumans Health Care Systems
Model
In this model, people are seen as open systems thatconstantly and reciprocally interact with theirenvironments.
Each system is greater than the sum of its parts, and
wellness exists when the parts of the system interact inharmony with each other and with the systemsenvironment.
Four sets of variables, or influences, make up each systemswhole. These are physiologic, psychological,sociocultural, and developmental variables.
Given these variables, each system has a unique responseto stressors and to those tension-producing stimuli thatmay cause disequilibrium or illness.
7/27/2019 Theoretical Basis Of
14/40
A systems response to stressors may be envisioned as aseries of concentric circles. In the center is a core of basicsurvival abilities, such as a communitys ability to make thebest use of its natural resources.
Surrounding this core are three boundaries. The innermostboundary is a flexible line of resistance that encompassesinternal defenses, such as a communitys collective sense ofresponsibility for raising healthy children.
The second boundary is the systems normal line ofdefense, such as a communitys police force or voluntaryfire brigade.
The third boundary is a dynamic, flexible line of defense, abuffer that prevents stressors from invading the systemsnormal line of defense.

Rogers Model of the Science
of Unitary Beings
Rogers is responsible for modern nursingsemphasis on the whole person
she developed a nursing conceptual modelbased on systems theory. Her modelemphasized that the whole is greater thanthe sum of its parts
7/27/2019 Theoretical Basis Of

Rogers also incorporated developmental theory into hermodel by describing the development of unitary personsor systems according to three principles: (1) life proceeds inone direction along a rhythmic spiral, (2) energy fieldsfollow a certain wave pattern and organization, and (3)human and environmental energy fields interactsimultaneously and mutually, leading to completeness andunity.
Using this model, the community health nurse can focus oncommunityenvironment interaction; the community
functions interdependently with others and with theenvironment.
The goal of community health nursing is to promote holisticand healthful communityenvironment interaction.

Penders Health Promotion
Model Pender defined health promotion as actions thatare directed toward increasing the level of well-being and self-actualization in individuals or
groups Penders health promotion model seeks to explain
this proactive behavior.
The model, based on social learning theory,
stresses cognitive processes that help regulatebehavior such as perceptions people have thatdirectly influence their motivation to begin orcontinue health-promoting behaviors.
7/27/2019 Theoretical Basis Of
20/40
Five types of modifying factors influencepeoples perceptions about pursuing health-promoting behaviors:
Demographic factors, such as age and race Biologic characteristics, such as height and weight
Interpersonal influences, such as the expectationsof others
Situational factors, such as availability ofhealthfulfoods
Behavioral factors, such as stress-coping patterns

Community-as-Partner Model
Based on Neumans model of a total-personapproach to viewing patient problems, thecommunity-as-client model was developed bythe authors to illustrate the definition of publichealth nursing as the synthesis of publichealth and nursing.
The model has been renamed the community-as-partner model to emphasize the underlyingphilosophy of primary health care.
7/27/2019 Theoretical Basis Of
22/40
Systems have a common purpose,interrelated parts, and boundaries.
The whole system is considered greater than
the sum of its parts, and there is emphasis onthe interaction of those parts to make up thewhole.
An individual, group, or community can beconsidered an open system in that there isconstant interaction with the environmentthrough boundaries.

There are two central factors in this model: afocus on the community as partner(represented by the communityassessmentwheel at the top, which incorporates thecommunitys people as the core) and the useof the nursing process.
The model is described in some detail to assistyou in understanding its parts; this will guideyour practice in the community.
7/27/2019 Theoretical Basis Of

The core of the assessment wheel represents thepeople who make up the community.
Included in the core are the demographics of thepopulation as well as their values, beliefs, andhistory.
As residents of the community, the people areaffected by and, in turn, influence the eightsubsystems of the community.
These subsystems are physical environment,education, safety and transportation, politics andgovernment, health and social services,communication, economics, and recreation.

The solid line surrounding the community
represents its normal line of defense, or the level
of health the community has reached over time.
The normal line of defense may include
characteristics such as a high rate of immunity,
low infant mortality,or middle-income level.
The normal line of defense also includes usualpatterns of coping, along with problem-solving
capabilities; it represents the health of thecommunity.

Theflexible line of defense, depicted as abroken line around the community anditsnormal line of defense, is a buffer zonerepresenting a dynamic level of healthresulting from a temporary response tostressors.

Within the community are lines of resistance,internal mechanisms that act to defendagainst stressors.
Lines of resistance exist throughout each ofthe subsystems and represent thecommunitys strengths.

Stressors are tension-producing stimuli that havethe potential of causing disequilibrium in thesystem.
They may originate outside the community (e.g.,air pollution from a nearby industry) or inside thecommunity (e.g., the closing of a clinic).
Stressors penetrate the flexible and normal lines
of defense, resulting in disruption of thecommunity. Inadequate, inaccessible, orunaffordable services are stressors on the healthof the community.
7/27/2019 Theoretical Basis Of
29/40
Stressors and lines of resistance (strengths)
together become part of the community nursing
diagnosis by giving rise to the degree of reaction.
The degree of reaction is the amount ofdisequilibrium or disruption that results from
stressors impinging on the communitys lines ofdefense.
The degree of reaction may be reflected in
mortality and morbidity rates, unemployment,
or crime statistics, to name a few.

SOCIETAL INFLUENCES ON COMMUNITY
ORIENTED,
POPULATION-FOCUSED NURSING Communication Technology
In addition, Internet technology has made it possible toaccess local, state, national, and international data forcommunity assessment, planning, and evaluation.
Nurses who require data for a new intervention strategy,for example, can search the Internet for information fromconsumer groups, researchers, and other expertsworldwide.
To keep apprised of emerging issues and trends in publichealth, the nurse can join numerous Internet-based
electronic discussion groups or listservs (electronicdiscussions distributed by way of email).
The challenge to the nurse is to manage the volume ofinformation and to weigh its worth.

Genetics, Genomics, and GeneticEngineering
Genetics, the science of heredity andgenomics, the study of the entire genome,are terms that have gained increasedattention from nurses over the past decade.
An outgrowth of this knowledge is geneticengineering, which can be defined as genemanipulation in a laboratory setting.
7/27/2019 Theoretical Basis Of
33/40
In addition to increasing understanding of the contributionof genetic material to health and disease, genetic researchhas created new opportunities for early identification,prevention, and treatment of people at risk for disease.
For example, techniques for DNA screening of newbornsallows early detection of risk for certain diseases anddisabilities, thereby permitting early intervention. Geneticcounseling, previously only available to a limitedpopulation, is being used increasingly by women in thepreconception and prenatal periods.
In dealing with these concerns, it is the community healthnurses responsibility to be aware of the latest scientificinformation when educating communities, so that thedecisions made best fit the communitys value system.

Global Economy A global economy also permits rich countries in need
of skilled workers to recruit them from developingcountries, causing a shortage of skilled labor in thosecountries that need it most.
In countries able to recruit labor, the presence of newimmigrant groups may be seen as a threat to the localculture or economy, causing an increase in ethnic,
racial, and religious tensions. Even people with jobs that pay well may react
negatively because they see their world changing andtheir own future as more uncertain.

The economic trends of the late 20thcenturyhave contributed to greater worldwidedisparities in wealth, health, and relative poverty,a measurement of an individuals income againstthe average for the society in which thatindividual lives.
Community health nurses have an obligation toread the latest research, so that they can better
understand the relationship of poverty to health. At the same time, they need to advocate
forpolicies that will reduce adverse effects ofpoverty and income disparities.

Migration Migration is the act of moving from one region or country to
another, either temporarily, seasonally, or permanently. The health care needs of migrants and migrant refugees are
enormous. Environmental factors are a primary reason for compromised
health, and include inadequate waste disposal, crowded andoften unsanitary living conditions, lack of access to healthfulfoods, and air pollution from an increased concentration ofvehicles used for moving refugees.
The potential detriments to health associated with migration
require that community health nurses ensure that surveillancesystems able to detect emerging health problems are in place;programs to prevent health problems and treat existingconditions also need to be developed.

Terrorism and Bioterrorism
Terrorism is one way in which a small number ofpeople who perceive that they have been unfairly
treated can exert influence on a larger group or nation. Bioterrorism is the use of living organisms, such as
bacteria, viruses, or other organic materials, to harmor intimidate others, in order to achieve political ends.
Some of the possible biologic agents used includeBacillus anthracis, smallpox virus, Brucella, andbotulinum toxin
7/27/2019 Theoretical Basis Of
38/40
Perhaps more importantly, community healthnurses need to be involved in primaryprevention of bioterrorism throughadvocating for the elimination of biologicweapons and addressing the root causes ofterrorism, such as poverty, hunger, poor
housing, limited educational opportunities,lack of clean water, and inadequate or nohealth care.

Climate Changes Climate changes can be considered societal changes because
they may be influenced by economics. Since the Industrial Revolution, increased amounts of carbon dioxide, methane, and
nitrous oxide created by manufacturing industries, automobile
emissions, and consumer products have been introduced into theearths atmosphere.
These increases have contributed to climate changes that areexpected to affect sea level; the production of food, fiber, andmedicines; and the spread of infectious diseases. Conversely,significant
Population focused nurses need to educate the public about thepotential dangers of continuing to contaminate the environmentand to advocate for changes in public policy that reduce air andwater contaminants.
