DEFINITION OF HEALTH
“ Health is a complete state of
physical , mental, social and
spiritual well being and not
merely as an absence of a
disease or infirmity”

CONCEPT OF
HEALTH
• Health is evolved over the centuries as a
concept from individual concern to world
wide social goal and encompasses the
whole quality of life. Changing concept
of health till now are:
– Biomedical concept
– Ecological concept
– Psychosocial concept
– Holistic concept

BIOMEDICAL
CONCEPT
5
• Traditionally, health has been viewed as
an “absence of disease”, and if one was
free from disease, then the person was
considered healthy.
• This concept has the basis in the “germ
theory of disease”.
• The medical profession viewed the
human
body as a machine,
disease
consequenceof the
breakdown
as
a
of
th
e
machine and one of the doctor’s task
as repair of the machine.

ECOLOGICAL
CONCEPT
6
• Form ecological point of
view;
health
i
s
viewed as a dynamic
equilibrium
betwee
n
human being and environment, and
disease a maladjustment of the human
organism to environment.
• According to Dubos “Health implies the
relative absence of pain and discomfort
and a continuous adaptation and
adjustment to the environment to ensure
optimal function.”
• The ecological concept raises two issues,
viz. imperfect man and imperfect

PSYCHOSOCIAL
CONCEPT
• According to psychosocial concept “health
is not only biomedical phenomenon, but
is influenced by social, psychological,
cultural, economic and political factors of
the people concerned.”
7

HOLISTIC
CONCEPT
8
• This concept is the synthesis of all the
above concepts.
• It recognizes the strength of social,
economic, political and environmental
influences on health.
• It described health as a unified or multi
dimensional process involving the
wellbeing of whole person in context of
his environment .

DIMENSIONS OF
HEALTH
9
• Health is multidimensional.
• World Health Organization explained
health in three dimensional
perspectives: physical, mental, social
and spiritual.
• Besides these many more may be
cited,
e.g. emotional, vocational, political,
philosophical, cultural, socioeconomic,
environmental, educational, nutritional,

PHYSICAL
DIMENSION
• Physical dimension views health form
physiological perspective.
• It conceptualizes health that as
biologically a state in which each and
every organ even a cell is functioning
at their optimum capacity and in
perfect harmony with the rest of
body.
• Physical health can be assessed at
community level by the measurement
of morbidity and mortality 9

MENTAL
DIMENSION
• Ability to think clearly and coherently. This
deals with sound socialization in
communities.
• Mental health is a state of balance
between the individual and the
surrounding world, a state of harmony
between oneself and others, coexistence
between the relatives of the self and that
of other people and that of the
environment.
• Mental health is not merely an absence of
mental illness. 11

Features of mentally healthy
person
• Free from internal conflicts.
• Well – adjusted in the external
environment.
• Searchesfor one’sidentity.
• Strong sense of self-esteem.
• Knows himself: his mind, problems and
goal.
• Have good self-controls-balances.
• Faces problems and tries to solve 12

SOCIAL
DIMENSION
• It refers the ability to make and
maintain relationships with other
people or communities.
• It states that harmony and integration
within and between each individuals
and other members of the society.
• Social dimension of health includes
the level of social skills one
possesses, social functioning and
the ability to see oneself as a
13

SPIRITUAL
DIMENSION
14
• Spiritual health is connected with religious
beliefs and practices. It also deals with
personal creeds, principles of behavior and
ways of achieving peace of mind and being
at peace with oneself.
• Itis intangible “something” that transcends
physiology and psychology.
• It includes integrity, principle and ethics, the
purpose of life, commitment to some higher
being, belief in the concepts that are not
subject to “state of art” explanation.

WELLNESS
Wellness is a state of well-being. Basic aspects of
wellness include
self-responsibility;
an ultimate goal;
a dynamic, growing process; daily decision making in the
areas of nutrition, stress management, physical fitness,
preventive health care, and emotional health; and, most
importantly, the whole being of the individual. Anspaugh,
Hamrick, and Rosato (2011) propose seven components
of wellness To realize optimal health and wellness,
people must deal with the factors within each
component:

WELL BEING
“Well-being is a subjective perception of vitality
and feeling well . . .can be described objectively,
experienced, and measured . . . and can be
plotted on a continuum” It is a component of
health.

CONCEPT OF
WELLBEING
• Wellbeing of an individual or group of
individuals have several components and
has been expressed in various ways,
such as ‘standard of living’ or ‘level of
living’ and ‘quality of live’.
17

STANDARD OF
LIVING
• Income and occupation,
standards of housing,
sanitation and nutrition,
the
level of
educationa
l,
provision
recreation
al
of
health
, and
other
services all be used individually as
measures of socioeconomic status,
and collectively as an index of the
standard of living.
18

LEVEL OF
LIVING
19
• It consists of nine components : health,
food consumption, education,
occupation and working conditions,
housing, social security, clothing,
recreation and leisure human rights.
• These objective characteristics are
believed to influence human wellbeing.
It is considered that health is the most
important component of the level of
living because its impairment always
means impairment of the level of living.

MODELS OF HEALTH AND
WELLNESS
Because health is such a complex concept,
various researchers have developed models or
paradigms to explain health and in some instances
its relationship to illness or injury. Models can be
helpful in assisting health professionals to meet the
health and wellness needs of individuals. Models
of health include the clinical model, the role
performance model, the adaptive model, the
eudaimonistic model, the agent–host–environment
model, and health–illness continua.

Clinical Model
The narrowest interpretation of health occurs in the
clinical model. People are viewed as physiological
systems with related functions, and health is
identified by the absence of signs and symptoms of
disease or injury. It is considered the state of not
being “sick.” In this model, the opposite of health is
disease or injury. Many medical practitioners have
used the clinical model in their focus on the relief of
signs and symptoms of disease and elimination of
malfunction and pain. When these signs and
symptoms are no longer present, the medical
practitioner considers the individual’s health
restored.

Role Performance Model
Health is defined in terms of an individual’s ability
to fulfill societal roles, that is, to perform his or her
work. People usually fulfill several roles (e.g.,
mother, daughter, friend), and certain individuals
may consider nonwork roles the most important
ones in their lives. According to this model, people
who can fulfill their roles are healthy even if they
have clinical illness. For example, a man who
works all day at his job as expected is healthy
even though he is partially deaf. It is assumed in
this model that sickness is the inability to perform
one’s work role.

Adaptive Model
In the adaptive model, health is a creative process;
disease is a failure in adaptation, or maladaptation.
The aim of treatment is to restore the ability of the
person to adapt, that is, to cope. According to this
model, extreme good health is flexible adaptation
to the environment and interaction with the
environment to maximum advantage. The famous
Roy adaptation model of nursing (Roy, 2009)
views the person as an adaptive system The focus
of this model is stability, although there is also an
element of growth and change.

Eudaimonistic Model
The eudaimonistic model incorporates a comprehensive view
of health. Health is seen as a condition of actualization or
realization of a person’s potential. Actualization is the apex of
the fully developed personality, described by Abraham Maslow
.In this model the highest aspiration of people is fulfillment and
complete development, which is actualization. Illness, in this
model, is a condition that prevents self-actualization. Pender,
Murdaugh, and Parsons (2011) include stabilizing and
actualizing tendencies in their definition of health: “the
realization of human potential through goal-directed behavior,
competent selfcare, and satisfying relationships with others
while adapting to maintain structural integrity and harmony
with the social and physical environments”

Another model of this type is that of Margaret
Newman (2008) who states that health is the
expansion of consciousness. The basic assumptions
of this model or theory are: Health is an evolving
unitary pattern of the whole, including patterns of
disease. Consciousness is the informational capacity
of the whole and is revealed in the evolving pattern.
Pattern identifies the human–environmental process
and is characterized by meaning.

Agent–Host–Environment
Model
The agent–host–environment model of health and
illness, also called the ecologic model, originated in
the community health work of Leavell and Clark
(1965) and has been expanded into a general theory
of the multiple causes of disease. The model is used
primarily in predicting illness rather than in promoting
wellness, although identification of risk factors that
result from the interactions of agent, host, and
environment are helpful in promoting and
maintaining health. The model has three dynamic
interactive elements

Agent–Host–Environment
Model

1. Agent: Any environmental factor or stressor
(biologic, chemical, mechanical, physical, or
psychosocial) that by its presence or absence
(e.g., lack of essential nutrients) can lead to
illness or disease
2. Host: Person(s) who may or may not be at risk of
acquiring a disease. Family
3. Environment: All factors external to the host that
may or may not predispose the person to the
development of disease. Physical environment
includes climate, living conditions, sound (noise)
levels, and economic level. Social environment
includes interactions with others and life events,
such as the death of a spouse.

Because each of the agent–host–environment
factors constantly interacts with the others, health
is an ever-changing state. When the variables are
in balance, health is maintained; when the
variables are not in balance, disease occurs.

Health–Illness Continua
Health–illness continua (grids or graduated scales) can be
used to measure a person’s perceived level of wellness.
Health and illness or disease can be viewed as the opposite
ends of a health continuum.
From a high level of health a person’s condition can move
through good health, normal health, poor health, and
extremely poor health, eventually to death. People move back
and forth within this continuum day by day. There is no distinct
boundary across which people move from health to illness or
from illness back to health. How people perceive themselves
and how others see them in terms of health and illness will
also affect their placement on the continuum. The ranges in
which people can be thought of as healthy or ill are
considerable.

DUNN’S HIGH-LEVEL
WELLNESS GRID
Dunn (1959) described a health grid in which a
health axis and an environmental axis intersect.
The grid demonstrates the interaction of the
environment with the illness–wellness continuum.
The health axis extends from peak wellness to
death, and the environmental axis extends from
very favorable to very unfavorable. The
intersection of the two axes forms four quadrants
of health and wellness

1. High-level wellness in a favorable environment. An
example is a person who implements healthy lifestyle
behaviors and has the biopsychosocial, spiritual, and
economic resources to support this lifestyle.
2. Emergent high-level wellness in an unfavorable
environment. An example is a woman who has the
knowledge to implement healthy lifestyle practices but
does not implement adequate selfcare practices because
of family responsibilities, job demands, or other factors.
3. Protected poor health in a favorable environment. An
example is an ill person (e.g., one with multiple fractures or
severe hypertension) whose needs are met by the health
care system and who has access to appropriate
medications, diet, and health care instruction.
4. Poor health in an unfavorable environment. An example
is a young child who is starving in a drought-stricken
country

ILLNESS–WELLNESS
CONTINUUM
The illness–wellness continuum developed by
Anspaugh, Hamrick, and Rosato (2011) ranges from
optimal health to premature death. The model
illustrates arrows pointing in opposite directions and
joined at a neutral point. Movement to the right of the
neutral point indicates increasing levels of health and
wellness for an individual. This is achieved through
health knowledge, disease prevention, health
promotion, and positive attitude. In contrast,
movement to the left of the neutral point indicates
progressively decreasing levels of health. Some
people believe that a health continuum is overly
simplistic and linear when the real concepts are

John W. Travis is an American author and
medical practitioner. He is a proponent of
the alternative medicine concept of "wellness",
originally proposed in 1961 by Halbert L. Dunn,
and has written books on the subject. In the 1970s,
Travis founded the first "wellness center" in
California.He originated the Illness–Wellness
Continuum

The Illness-Wellness Continuum is a graphical
illustration of a wellbeing concept first proposed by
Travis in 1972. It proposes that wellbeing includes
mental and emotional health, as well as the
presence or absence of illness
Travis believed that a medical approach that relied
on the presence or absence of symptoms of
disease to demonstrate wellness was insufficient.
As shown in the Continuum, the right side reflects
degrees of wellness, while the left indicates
degrees of illness.The model has been used to
describe how, in the absence of physical disease,
an individual can suffer from depression, anxiety or
other conditions.

He contends that medicine typically treats injuries,
disabilities, and symptoms, to bring the individual
to a "neutral point" where there is no longer any
visible illness. However, the Wellness Paradigm
requires moving the state of wellbeing further
along the continuum towards optimal emotional
and mental states.The concept assumes that
wellbeing is a dynamic rather than a static process.
The Illness-Wellness Continuum proposes that
individuals can move farther to the right, towards
greater health and wellbeing, passing through the
stages of awareness, education, and
growth.Worsening states of health are reflected by
signs, symptoms and disability.

TRAVIS ILLNESS WELLNESS
CONTINNUM

HEALTH ILLNESS
CONTINUUM
• According to Newman (1990) "Health on a
continuum is the degree of client wellness that
exists at any point in time, ranging from an
optimal wellness condition with available energy
at its maximum to death, which represents total
energy depletion.“
• According to Health-illness continuum model,
'Health is a dynamic state that continuously
alters as a person adapts to changes in the
internal and external environments to maintain a
state of physical, emotional, intellectual, social,
developmental and spiritual well-being. Illness is
a process in which the functioning of a person
is diminished or impaired in one or more
dimensions when compared with the person's
previous condition'.

HEALTH BELIEF
MODELS
Several theories or models of health beliefs and
behaviors have been developed to help determine
whether an individual is likely to participate in
disease prevention and health promotion activities.
These models can be useful tools in developing
programs for helping people with healthier
lifestyles and more positive attitudes toward
preventive health measures .

Health Locus of Control
Model
Locus of control is a concept from social learning theory that
nurses can use to determine whether clients are likely to take
action regarding health, that is, whether clients believe that their
health status is under their own or others’ control. People who
believe that they have a major influence on their own health
status—that health is largely self-determined—are called
internals. People who exercise internal control are more likely
than others to take the initiative on their own health care, be
more knowledgeable about their health, make and keep
appointments with primary care providers, maintain diets, and
give up smoking. By contrast, people who believe their health is
largely controlled by outside forces (e.g., chance or powerful
others) are referred to as externals.

Rosenstock and Becker’s Health
Belief Models
Rosenstock and Becker’s health belief model
(Rosenstock, Strecher, & Becker, 1988) is based on
the assumption that health-related action depends
on the simultaneous occurrence of three factors: (1)
sufficient motivation to make health issues be viewed
as important, (2) belief that one is vulnerable to a
serious health problem or its consequences, and (3)
belief that following a particular health
recommendation would be beneficial. The model
includes individual perceptions, modifying factors,
and variables likely to affect initiating action

HEALTH CARE
ADHERENCE
Adherence is the extent to which an individual’s
behavior (for example, taking medications,
following diets, or making lifestyle changes)
coincides with medical or health advice. Degree of
adherence may range from disregarding every
aspect of the recommendations to following the
total therapeutic plan. There are many reasons
why some people adhere and others do not. To
enhance adherence, nurses need to ensure that
the client is able to perform the activities,
understands the necessary instructions, is a willing
participant in establishing goals of therapy, and
values the planned outcomes of behavior changes.

• The simplest definition is that disease is
just the opposite of health: i.e. any
deviation from normal functioning or
state of complete physical or mental
well-being.

Disease, Illness and
Sickness
• The term disease literally means
“without ease” (uneasiness), when
something is wrong with bodily
function.
• Illness refers to the presence of a
specific disease, and also to the
individual’s perceptions and behavior in
response to the disease, as well as the
impact of that disease on the
psychosocial environment.
• Sickness refers to a state of
dysfunction.
soci
al

Distinction between
Disease, Illness and
Sickness
• Disease is a physiological/psychological
dysfunction.
• Illness is a subjective state of the
person who feels aware of not being
well.
• Sickness is a state of social dysfunction
i.e. a role that the individual assumes
when ill (sickness role).

Causes developing illness
• hereditary problems or family history
example diabetics mellitus hypertension cancer
chromosomal problems
• Environmental causes : air pollution noise
pollution overcrowded area for sanitation
• poor nutrition: malnutrition low weight vitamin

eating hot and spicy foods ,tobacco and
narcotic use BD ,cigarette, Nut showing

Risk Factors for Illness or
Injury
A risk factor is something that increases a person’s
chances for illness or injury. Like other components
of health and illness, risk factors are often
interrelated. Risk factors may be further defined as
modifiable (able to be changed, such as quitting
smoking) or nonmodifiable (unable to be changed,
such as a family history of cancer). As the number of
risk factors increases, so does the possibility of
illness. For example, an overweight executive, under
pressure to increase sales, smokes and drinks
alcohol in excess. These factors, combined with a
family history of heart disease, place this person at
higher risk for illness. The six general types of risk

Classifications of Illness
Illnesses are classified as either acute or chronic. A person
may have an acute illness, a chronic illness, or both at the
same time; for example, an adult with diabetes (a chronic
illness) may also have appendicitis (an acute illness).
Acute Illness and Illness Behaviors An acute illness usually
has a rapid onset of symptoms and lasts only a relatively short
time. Although some acute illnesses are life threatening, with
self-treatment and use of over-the-counter medications simple
acute illnesses, such as the common cold or diarrhea, do not
usually require medical treatment. If medical care is required, a
specific treatment with medications (e.g., antibiotics for
pneumonia) or surgical procedures (e.g., an appendectomy for
appendicitis) usually return the person to normal functioning.
When a person becomes acutely ill, certain illness behaviors
may occur in identifiable stages (Suchman, 1965).

ILLNESS BEHAVIOUR
STAGE 1: EXPERIENCING SYMPTOMS
How do people define themselves as “sick”? The
first indication of an illness usually is recognizing
one or more symptoms that are incompatible with
one’s personal definition of health. Although pain is
the most significant symptom indicating illness,
other common symptoms include a rash, fever,
bleeding, or a cough. If the symptoms last for a
short time or are relieved by self-care, the person
usually takes no further action. If the symptoms
continue, however, the person enters the next
stage.

STAGE 2: ASSUMING THE SICK ROLE
The person now defines himself or herself as being
sick, seeks validation of this experience from
others, gives up normal activities, and assumes a
“sick role.” At this stage, most people focus on their
symptoms and bodily functions. Depending on
individual health beliefs and practices, the person
may choose to do nothing, may buy over-the-
counter medications to relieve symptoms, or may
seek out a healthcare provider for diagnosis and
treatment. In our society, an illness becomes
legitimate when a healthcare provider diagnoses it
and prescribes treatment. When help from the
healthcare provider is sought, the person becomes
a patient and enters the next stage

STAGE 3: ASSUMING A DEPENDENT ROLE
This stage is characterized by the patient’s
decision to accept the diagnosis and follow the
prescribed treatment plan. The person conforms to
the opinions of others, often requires assistance in
carrying out activities of daily living, and needs
emotional support through acceptance, approval,
physical closeness, and protection

STAGE 4: ACHIEVING RECOVERY AND
REHABILITATION Recovery and rehabilitation
might begin in the hospital and conclude at home,
or may be totally concluded at a rehabilitation
center or at home. Most patients complete this final
stage of illness behavior at home. In this stage, the
person gives up the dependent role and resumes
normal activities and responsibilities. If the plan of
care includes health education, the individual may
return to health at a higher level of functioning and
health than before the illness.

Chronic Illness
Chronic illness is a broad term that encompasses
many different physical and mental alterations in
health, with one or more of the following
characteristics:
• It is a permanent change.
• It causes, or is caused by, irreversible alterations
in normal anatomy and physiology.
• It requires special patient education for
rehabilitation.
• It requires a long period of care or support

Chronic illnesses usually have a slow onset and many
have periods of remission (when the disease is present,
but the person does not experience symptoms) and
exacerbation (the symptoms of the disease reappear).
Examples of common chronic illnesses are heart
disease, diabetes mellitus, lung diseases, and arthritis.

Illness Behaviors
When people become ill, they behave in certain
ways that sociologists refer to as illness behavior.
Illness behavior, a coping mechanism, involves
ways individuals describe, monitor, and interpret
their symptoms, take remedial actions, and use the
health care system. How people behave when they
are ill is highly individualized and affected by many
variables, such as age, sex, occupation,
socioeconomic status, religion, ethnic origin,
psychological stability, personality, education, and
modes of coping.

Parsons (1979) described four aspects of the sick
role.
Rights:
1. Clients are not held responsible for their
condition. Even if the illness was partially
caused by an individual’s behavior (e.g., lung
cancer from smoking), the individual is not
capable of reversing the condition on his or her
own.
2. Clients are excused from certain social roles
and tasks. For example, an ill parent would not
be expected to prepare meals for the family.

Obligations:
3.Clients are obliged to try to get well as
quickly as possible. The ill person should
follow legitimate advice regarding a
specialized diet or activity restrictions that
could help with recovery.
4. Clients or their families are obliged to
seek competent help. For example, the ill
person should contact the primary care
provider rather than relying solely on his or
her own ideas of how to recove

Suchman (1979) described five stages of illness:
 symptom experiences
 assumption of the sick role
 medical care contact
 dependent client role
 recovery or rehabilitation.
Not all clients progress through each stage. For
example, the client who experiences a sudden
heart attack is taken to the emergency department
and immediately enters stages 3 and 4, medical
care contact and dependent client role. Other
clients may progress through only the first two
stages and then recover. Details of Suchman’s five
stages follow

STAGE 1: SYMPTOM
EXPERIENCES
At this stage the person comes to believe something is
wrong. Either someone significant mentions that the
person looks unwell, or the person experiences some
symptoms such as pain, rash, cough, fever, or
bleeding. Stage 1 has three aspects:
• The physical experience of symptoms
• The cognitive aspect (the interpretation of the
symptoms in terms that have some meaning to the
person)
• The emotional response (e.g., fear or anxiety).

During this stage, the unwell person usually
consults others about the symptoms or feelings,
validating with support people that the symptoms
are real. At this stage the sick person may try
home remedies. If self-management is ineffective,
the individual enters the next stage.

STAGE 2: ASSUMPTION OF
THE SICK ROLE
The individual now accepts the sick role and seeks
confirmation from family and friends. Often people
continue with self-treatment and delay contact with
health care professionals as long as possible.
During this stage people may be excused from
normal duties and role expectations . Emotional
responses such as withdrawal, anxiety, fear, and
depression are not uncommon depending on the
severity of the illness, perceived degree of disability,
and anticipated duration of the illness. When
symptoms of illness persist or increase, the person
is motivated to seek professional help

STAGE 3: MEDICAL
CARE CONTACT
Sick people seek the advice of a health professional
either on their own initiative or at the urging of
significant others. When people seek professional
advice, they are really asking for three types of
information:
• Validation of real illness
• Explanation of the symptoms in understandable terms
• Reassurance that they will be all right or prediction of
what the outcome will be.

The health professional may determine that the
client does not have an illness or that an illness is
present and may even be life threatening. The
client may accept or deny the diagnosis. If the
diagnosis is accepted, the client usually follows the
prescribed treatment plan. If the diagnosis is not
accepted, the client may seek the advice of other
health care professionals or quasi-practitioners
who will provide a diagnosis that fits the client’s
perceptions.

STAGE 4: DEPENDENT
CLIENT ROLE
After accepting the illness and seeking treatment, the
client becomes dependent on the professional for
help. People vary greatly in the degree of ease with
which they can give up their independence,
particularly in relation to life and death. Role
obligations—such as those of wage earner, parent,
student, sports team member, or choir member—
complicate the decision to give up independence.

Most people accept their dependence on the primary
care provider, although they retain varying degrees
of control over their own lives. For example, some
people request precise information about their
disease, their treatment, and the cost of treatment,
and may delay the decision to accept treatment until
they have all this information. Others prefer that the
primary care provider proceed with treatment and do
not request additional information. For some clients,
illness may meet dependence needs that have never
been met and thus provide satisfaction. Other people
have minimal dependence needs and do everything
possible to return to independent functioning. A few
may even try to maintain independence to the
detriment of their recover

STAGE 5: RECOVERY
OR REHABILITATION
During this stage the client is expected to
relinquish the dependent role and resume former
roles and responsibilities. For people with acute
illness, the time as an ill person is generally short
and recovery is usually rapid. Thus most find it
relatively easy to return to their former lifestyles.
People who have long-term illnesses and must
adjust their lifestyles may find recovery more
difficult. For clients with a permanent disability, this
final stage may require therapy to learn how to
make major adjustments in functioning

Effects of Illness
Illness brings about changes in both the involved
individual and in the family. The changes vary
depending on the nature, severity, and duration of
the illness, attitudes associated with the illness by
the client and others, the financial demands, the
lifestyle changes incurred, adjustments to usual
roles, and so on

IMPACT ON THE CLIENT
Ill clients may experience behavioral and emotional
changes, changes in self-concept and body image,
and lifestyle changes. Behavioral and emotional
changes associated with short-term illness are
generally mild and short lived. The individual, for
example, may become irritable and lack the energy
or desire to interact in the usual fashion with family
members or friends. More acute responses are likely
with severe, life-threatening, chronic, or disabling
illness. Anxiety, fear, anger, withdrawal, denial, a
sense of hopelessness, and feelings of
powerlessness are all common responses to severe
or disabling illness.

Nurses can help clients adjust their lifestyles by
these means:
• Provide explanations about necessary
adjustments.
• Make arrangements wherever possible to
accommodate the client’s lifestyle.
• Encourage other health professionals to become
aware of the person’s lifestyle practices and to
support healthy aspects of that lifestyle.
• Reinforce desirable changes in practices with a
view to making them a permanent part of the
client’s lifestyle

IMPACT ON THE
FAMILY
A person’s illness affects not only the person who
is ill but also the family or significant others. The
kind of effect and its extent depend chiefly on three
factors: (1) the member of the family who is ill,
(2) the seriousness and length of the illness, and
(3) the cultural and social customs the family
follows.

The changes that can occur in the family
include the following: • Role changes • Task
reassignments and increased demands on time •
Increased stress due to anxiety about the outcome
of the illness for the client and conflict about
unaccustomed responsibilities • Financial problems
• Loneliness as a result of separation and pending
loss • Change in social customs

BODY DEFENCE:
IMMUNITY
The Body Defence Against Infection
 The first line of defense against infection to the
body is the normal flora/non specific defense,
which helps to keep harmful bacteria from
invading the body.
 Eg. Mechanical and Chemical Barriers:- It
involves the skin and mucous membrane. In
these membranes, there are densely packed
cells that protect the internal environment from
the invasion by foreign cells. Substances such
as sebum, mucus, HCI in gastric mucosa act as
non-specific defences.

BODY DEFENCE:
IMMUNITY
The Immune Response
Involves nonspecific reactions in the body
as it responds to an invading foreign
protein such as bacteria, and in some
cases, the body’s own bacteria.
 A complex mechanism that swing into
action as the body attempts to protect and
defend its self.
Antigen – the foreign body and the body
responds to the antigen by producing an
antibody.

BODY DEFENCE:
IMMUNITY
The inflammatory response
The inflammatory response is a
protective mechanism that
eliminates the invading pathogen
and allow tissue to repair by
neutralising, controlling or
eliminating the harmful agent and
prepares the site for repair.

BODY DEFENCE:
IMMUNITY
Types of Immunity
1. Innate immunity : the natural
defence against infectious agent.
2. Active immunity : Acquired naturally
after exposure to infection or it could be
artificially acquired immunity resulting
from administration of vaccine.
3. Passive immunity : naturally
transferred from mother to fetus orcould
be by the artificial transfer of antibodies
by parenteral administration.

BODY DEFENCE:
IMMUNIZATION
• Immunization is the process by which an
individual immune system becomes
fortified against an agent.
• When the system is exposed to molecules
that are foreign to the body, an immune
response is set off, and the body
develops the ability to quickly respond to a
subsequent encounter because of
immunological immunity that has been
acquired.
• T cells, B cells and antibodies are
improved by immunisation.

• Vaccination
• Introduction of
Foreign molecules

• TT – 10+ 15 Yrs.

Spectrum of Health:
• -Positive Health, Better Health
• -Unrecognized sickness,
• -Mild sickness,
• -Severe sickness,
• -Death.
• The spectrum indicates that health of a person
is not a static condition, there arc always
continuous changes that come in the health
status and it is not possible to attain health
once and for all.

• The literature supports the view that health and its
attainment is a central concept and a goal of
nursing practice.
1. A nurse can determine a client's level of health at
any point on health illness continuum. A client's risk
factors (variables) are important in identifying level
of health. Risk factors include genetic and
physiological variables.
2 As a person progresses through the
developmental stages, certain risk factors are
common than others, e.g. Body image changes and
self-concept.
3. To help clients set goals to reach an optimal level
of health, the nurse helps them identify their

LEVELS OF
PREVENTI
ON
94
Primordial Prevention :
• Prevention from Risk Factors.
• Prevention of emergence or
development of Risk Factors.
• Discouraging harmful life styles.
• Encouraging or promoting healthy
eating habits.

LEVELS OF
PREVENTI
ON
95
Primary Prevention:
• Pre-pathogenesis Phase of a disease.
• Action taken prior to the onset of the
disease:
• Immunization & Chemo-prophylaxis

LEVELS OF
PREVENTI
ON
96
Secondary Prevention:
• Halt the progress of a disease at its
incipient phase.
• Early diagnosis & Adequate
medical treatment.
Tertiary Prevention:
• Intervention in the late Pathogenesis
Phase.
• Reduce impairments, minimize
disabilities & suffering.

MODES OF
INTERVENTION
97
• Intervention is any attempt to intervene or
interrupt the usual sequence in the
development
of disease. Five modes of intervention
corresponding to the natural history of any
disease are:
–Health Promotion
–Specific Protection
–Early Diagnosis and Adquate Treatment
–Disability Limitation
–Rehabilitation

HEALTH
PROMOTION
98
• It is the process of enabling people to
increase control over diseases, and to
improve their health. It is not directed
against any particular disease but is
intended to strengthen the host through a
variety of approaches(interventions):
–Health Education
–Environmental Modifications
–Nutritional Interventions
–Lifestyle and Behavioral Change

SPECIFIC
PROTECTION
99
• Some of the currently available
interventions aimed at specific protection
are:
– Immunization
– Use of specific Nutrients
– Chemoprophylaxis
– Protection against Occupational Hazards
– Avoidance of Allergens
– Control of specific hazards in
general environment
– Control of Consumer Product Quality &
Safety

EARLY DIAGNOSIS &
TREATMENT
10
0
• Though not aseffective and economical as‘Primary
Prevention’, early detection and treatment are the
main interventions of disease control, besides
being critically important in reducing the high
morbidity and mortality in certain diseases like
hypertension, cancer cervix, and breast cancer.
• The earlier the disease is diagnosed and
treated the better it is from the point of view of
prognosis and preventing the occurrence of
further cases (secondary cases) or any long
term disability.

DISABILITY
LIMITATIONS
10
1
• The Objective is to prevent or halt
the transition of the disease
process from impairment to
handicap.
Sequence of events leading to
disability & handicap:
• Disease→Impairment →Disability→ Handicap

DISABILITY
LIMITATIONS

2
• Impairment: Loss or abnormality of
psychological,
physiological/anatomical structure
or function.
• Disability: Any restriction or lack of ability
to perform an activity in a manner
considered normal for one’s age,sex,etc.
• Handicap: Any disadvantage that prevents
one from fulfilling his role considered
normal.

REHABILITATI
ON

3
• Rehabilitation has been defined as the
‘combined and coordinated useof medical,
social, educational and vocational
measures for training and retraining the
individual to the highest possible level of
functionalability”
• Areas of concern in rehabilitation:
– Medical Rehabilitation
– Vocational Rehabilitation
– Social Rehabilitation
– Psychological Rehabilitation

CONCEPT OF
CONTROL
10
4
• DISEASE CONTROL: The term disease
control refers ongoing operation aimed
at reducing:
– The incidence of disease.
– The duration of disease and the
consequently the risk of transmission.
– The effect of infection including physical
and psychological complication.
– The financial burden to the community.

CONCEPT OF
CONTROL
10
5
• In disease control, the disease agent is
permitted to persist in the community at a
level where it ceases to be a public health
problem according to the tolerance of local
community. For example Malaria control
programme. Disease control activities
focus on primary prevention

CONCEPT OF
CONTROL
10
6
ELIMINATION: Reduction of case
transmission to a predetermined very low
level or interruption in transmission. E.g.
measles, polio, leprosy from the large
geographic region or area.
ERADICATION: Termination of all
transmission of infection by extermination of
the infectious agent through surveillance
and containment.
“All or none phenomenon”. E.g.Smallpox

CONCEPT OF
CONTROL

• MONITORING: Defined as“the performance
and analysis of routine measurement aimed
at detecting changes in the environment or
health status of population.” e.g. growth
monitoringof child, Monitoring of air
pollution, monitoring of water quality etc.
• SURVEILLANCE: Defined as“the
continuous scrutiny of the factors that
determine the occurrence and distribution
of disease and other conditions of ill health.”
E.g.Poliomyelitis surveillance
programme of WHO.

It means that health service
must shared equally by all people
irrespective of their ability to pay, and
all the people rich or poor, rural or
urban must have access to health
services because the distribution of
health & family welfare services, & also
other related services, i.e. educative
income.

COMMUNITY
PARTICIPATIO
N:-
 It is the process by which individual,
families & communities assume
responsibilities in promoting their own
health & welfare.
 For the success of primary health care,
community involvement & participation will
be most vital. Community involvement
concerned with the levels of community
resident participation in health decision
making.
 To promote the development of the
community & the community’s self reliance,
resident themselves need to participate in
decision about health of the community.
Resident & health providers need to work
together in partnership to seek solution to
the complex problem facing community

APPROPRIATE HEALTH
TECHNOLOGY:-
• Appropriate technology refers to health care
that is relevant to people’s needs & concerns as
well as being acceptable to them.
• It includes issues of costs & affordability of
resources as the number & type of health
professionals & other worker, equipment & their
pattern of distribution throughout the community.
• In other words “ appropriate technology means
those which are decentralized, require low capital
investment, conserve natural resources, are
managed by their users, & are in harmony with
the environment.
• Thus appropriate technology is the technology
which is scientifically or technically sound,
adaptable to local needs, culturally acceptable &
financially feasible.

MULTI SECTORIAL
APPROACH:-
• Health & family welfare programmes
cannot stand on its own in an isolated manner.
• it is recognized that health of a community
cannot be improved by intervention within just
health sector; other sectors are equally
important in promoting the communities health
& self reliance.
• These are agriculture, irrigation, animal

of a social and medical organization, the function
of which is to provide for the population, the
complete health care, both curative and preventive
and whose outpatient services reach out to the
family and its home environment. The hospital is
also a Centre for the training of health worker and
for bio-social research.

Classification of
Hospitals
The most commonly accepted criteria for
classification of modern hospital are
according to:-
• Length of stay of patient (Long term,
Short term)
• Clinical basis
• Ownership/control basis
• Objectives
• Size
• Management
• System of medicine

• Classification according to length of stay of
patient :- A patient stays for a short time in
hospital for treatment of disease that is acute in
nature, such as pneumonia, peptic ulcer etc. A
patient may stay for a long term in a hospital for
treatment of diseases that are chronic in nature
such as TB, Leprosy, cancer etc. The hospitals
according to long term and short term are also
known as chronic care hospitals and acute care
hospitals.
• Classification according to Clinical Basis :-
These are the licensed hospitals and are
considered as general hospitals, treat all kinds of
diseases, major focus on treating condition such

Classification according to
ownership/ control
• On the basis of
ownership/Control, hospitals
can be divided into four
categories:
• Public hospitals.
• Voluntary hospitals.
• Private!/charitable hospitals/
nursing houses,
• Corporate hospitals,

CLASSIFICATION
ACCORDING TO
OBJECTIVES:-
• TEACHING CUM REASEARCH HOSPITAL - It is a
hospital to which a college is attached for
medical/nursing/ dental/pharmacy education, the main
objective of these hospitals is teaching based on
research and the provision of health care is secondary.
e.g.:- f IMS, PCIMER, Chandigarh.
• GENERAL HOSPITAL ;-Are those which provide
treatment for common diseases and conditions. The
main objectives of these hospitals are to provide medical
care to the people. e.g.:- All distinct and taluses or PHC
or rural hospitals belong to this type.
• SPCIALIZED HOSPITAL: are those that provide medical
and nursing care primarily for only one discipline on a
specific disease or condition of one system such as TB,
ENT, Leprosy, STD's etc.
• ISOLATION HOSPITAL:- are those hospitals in which
the persons suffering from infectious/ communicable
diseases require isolation. e.g.:- Epidemic disease
hospital, Bangalore .

CLASSIFICATION ACCORDING TO
SIZE
1. Teaching hospital - 500 (bed to be
increased according to number of
students).
2. District Hospital- 200 (bed to be
increased upto 300 depending upon
population).
3. Taluka Hospital - 50 (May be raised
depending upon population to be
served).

CLASSIFICATION
ACCORDING TO
MANAGEMENT
• UNION GOVERNMENT/GOVERNMENT OF INDIA:- All
hospitals administered by the government of India. e.g:-
Hospitals run by Railways, military/ defense etc.
• STATE GOVERNMENT: - Hospitals administered by
state/ union territory including police, prison, irrigation
department etc
• LOCAL BODIES:- Hospitals are administered by local
bodies i.e,muncipal corporation, zila prishad, panchayat
etc. e.g:- co- operation maternity houses.
• AUTONOMUS BODIES: - All hospitals established under
special act of parliament or state legislation and founded
by the central/ state government e.g. AIlMS, PCI etc.
• PRIVATE:-All private hospitals are owned by an
individual or by private Organization e.g.: MAHC
Manipal, Hinduja Hospital.
• Voluntary agency: - All hospitals are operated by a
voluntary body/ a trust/charitable society etc. It includes
hospitals run by missionary bodies and co-operations.
e.g: CMC, Vellore

CLASSIFICATION
ACCORDING TO
SYSTEM
• Allopathic hospitals,
• Ayurveda hospitals
• Homeopathic hospitals,
• Unani hospitals,
• Hospitals of other systems
of medicine.

FUNCTIONS OF
HOSPITAL
• Care of sick and Injured:- Hospital is an medical
institution where client suffering from some
disease/health problem is getting treated and cared.
Comprehensive care is provided to the sick/injured
client by health care team. Clients are treated
according to priority or needs. For example:
Emergency care is provided to client with Heart
attack than the client came with general weakness.
• prevention of disease:-. Prevention of disease is
accomplished by early screening, detection of risk
prone cases. Maintaining aseptic technique, following
the principles of medical care can prevent the
occurrence of certain complications. For example:
Immunization schedule for children, tetanus injection
during pregnancy.
• promotion of health:- A client who is maintaining his
health can accomplish higher level of health. In
hospital setting, various aspects of health promotion
are taken. For example: Health education,

• Diagnosis and treatment of diseases:- As
