4. What is Health?
“[Health is]
the state of complete physical,
mental and social well-being and not
merely the absence of disease or
infirmity”
(WHO, 1948)

5. What is Health?
Health is a resource for everyday
life, not the objective of living; it is a
positive concept, emphasizing social
and personal resources as well as
physical capabilities”
(WHO, 1984).

Community Medicine : Focus
Clinical medicine focuses
primarily on the individual, while
public health focuses on the
community.

9. C
Relevant time frames in Clinical Medicine are
usually single lifetimes,
while public health thinks in terms
of generations.
Clinical Medicine Vs
Community Medicine : Time Frame9
10. C
From an ethics perspective, clinicians
advocate for individual people.
Public health practitioners advocate for the
community, for a group of
people.
Clinical Medicine Vs
Community Medicine : Ethics10
11. C
In clinical medicine we focus on
individual rights of a patient. In
public health, we think about human
rights, social, and
environmental integrity.
Clinical Medicine Vs
Community Medicine : Ethics11
12. C
From an education perspective, in clinical medicine
In clinical medicine we focus on the
biomedical model with more emphasis
on cure than prevention. In public health, we
learn more about sociology,
epidemiology, cultural
anthropology, economics and
more.
Clinical Medicine Vs
Community Medicine : Education12
13. C
From an education perspective, in clinical medicine
In clinical medicine the evidence was drived
from Randomized Clinical Trials .
In public health, we depend mainly upon
Epidemiological Field Studies.

14. Community Diagnosis Component
Community Medicine has been
defined as that specialty which deals
with populations, and comprises
those doctors who try to measure
the needs of the population, both
sick and well, who plan and
administer services to meet those
needs, and those who are engaged in
research and teaching in the field.
14
15. Community medicine
The field concerned with the study of health and
disease in the population of a defined community or
group
Its goalis identification of the heath problems and
needs of the community and to plan implement and
evaluate interventions
It involves provision of health care at the
community level with their full participation
16. Community health/ Community medicine
Communityhealthdeals with all the services
that is aimed at protecting the health of the community

Curative
Rehabiltative
Communitymedicinelooks at the medical
and clinical services provided by physician and nurses
but in a defined community
17. Definition of a “Community”
A cluster of people with at least one
common characteristic (geographic
location, occupation, ethnicity, housing
condition……)
A group of people with a common
characteristic or interest living together
within a larger society

18. Dimensions of the Community
Any community having three features:
(1) Location,
(2) Population
(3)Social system

19. Community Profile Relating
to location variables?
Boundaries (incidence of wellness and illness and spread of
disease)
1. Where is the community located?
2. What is its boundaries?
3. Is it part of a larger community?
4. What smaller communities does it include?

2. Are there necessary health services outside the community?
Where?

is greatly influenced by the
population that lives in it
22
23. B- Population Variables
Size: Affects number and size of health care institutions
Homogeneity of population and its needs
What is the population?Is it urban suburban or rural?
Density: What is the density per square mile? Increased
density increases stress. High and low density affect the
availability of health services
Composition: What is the age composition? Sex
composition? Marital status? Occupations and %
Rate of growth or decline: How has population size
changed over the past two decades? Health implications of
this change?

c. Social System
the circumstances in which people are born,
grow up, live, work, and age, as well as the
systems put in place to deal with illness. These
circumstances are in turn shaped by a wider set
of forces: economics, social policies, and politics.

• Monitor health status
• Diagnose and investigate
• Inform, educate, and
empower
• Mobilize community
partnerships
• Develop policies and plans
• Enforce laws and
regulations
• Link people to needed
services / assure care
• Assure a competent
workforce
• Evaluate health services
• Research
34. Monitor Health to Identify
and Solve Community Health Problems
Accurate, periodic assessment of the
community’s health status, including:
Identification of health risks
Attention to vital statistics and disparities
Identifications of assets and resources
Utilization of methods and technology (e.g.,
GIS) to interpret and communicate data
Population health registries
35. Diagnose and Investigate Health
Problems and Hazards in the
Community
Timely identification and
investigation of health threats
Availability of diagnostic services,
including laboratory capacity
Response plans to address major
health threats
38. According to WHO definition
it is “a quantitative and qualitative
description of the health of citizens
and the factors which influence
their health. It identifies problems,
proposes areas for improvement
and stimulates action”.

39. Community diagnosis is a
comprehensive assessment of
health status of the community
in relation to its social, physical
and biological environment.
39
Community Diagnosis
40. Community Diagnosis
It should be the first stage in planning health
programs for the betterment and the improvement
of any community.
It includes:
Definition of the community’s demographic
characteristics .
Environment .
Health status ..
Available health and social services. .
40
41. The purpose of community diagnosis
is to define existing problems,
determine available resources and
set priorities for planning,
implementing and evaluating
health action, by and for the
community.

Community Diagnosis
42. Community analysis is the process of
examining data to define needs
strengths, barriers, opportunities,
readiness, and resources. The
product of analysis is the
“community profile”.
42
Community Analysis
43. the regular collection,
analysis and sharing of
information about health
conditions, risks and
resources in a community.

Community Assessment
45. Identify trends in illness, injury, and death and
the factors, which may cause these events.
Identify available resources and their
application
Identify unmet needs

elderly, unemployed/underemployed people,
women without prenatal care, troubled teens,
children behind on immunizations, low birth weight

Community Diagnosis: Uses
47. Importance of Com. Diagnosis
Provides baseline information about the health
status of community residents.
Ensures that decisions are based on solid
information and evidence.
Helps set priorities.
Helps Regional Health Authorities assess
outcomes and results in the longer term.
47
48. Importance of Com. Diagnosis
Gets community members, stakeholders and a
wide variety of partners
involved in the decision-making process, helps
them understand the difficult choices that need
to be made, and builds support and
commitment for addressing health needs on a
community-wide basis..

49. Importance of Com. Diagnosis
Can be used to guide policy and program
development.
Can assist in mapping out links and
interdependence to other sectors.
Can provide insight into the fundamental
causes and pathways of identify opportunities
for disease prevention, health promotion and
health protection.

measures that are designed to
describe particular aspects of
health or health system
performance.

Health Indicators
55. Characteristics of Indicators:
a. should be valid, i.e., they should actually
measure what they are supposed to
measure;
b. should be reliable and objective, i.e., the
answers should be the same if measured
by different people in similar
circumstances;
c. should be sensitive, i.e., they should be
sensitive to changes in the situation
concerned,
55
56. Characteristics of Indicators:
d. should be specific, i.e., they should
reflect changes only in the situation
concerned,
e. should be feasible, i.e., they should have
the ability to obtain data needed, and;
