- How we do it Public health practice is based on
scientifically sound strategies
for improving the quality of life and reducing
morbidity and premature mortality.
Prevention is the primary
obligation of public health.

Distinctions Between PH and Medicine
PUBLIC HEALTH
•
•
•
Primary focus on population
Public service ethic, tempered by
concerns for the individual
Emphasis on prevention, health
promotion for the whole community
MEDICINE
•
•
•
•
•
•
•
Public health paradigm employs a
spectrum of interventions aimed at
the environment, human behavior
and lifestyle, and medical care
Multiple professional identities with
diffuse public image
Variable certification of specialists
beyond professional public health
degree
•
•
Primary focus on individual
Personal service ethic, conditioned by
awareness of social responsibilities
Emphasis on diagnosis and treatment, care
for the whole patient
Medical paradigm places predominant
emphasis on medical care
Well-established profession with sharp
public image
Uniform system for certifying specialists
beyond professional medical degree

PUBLIC HEALTH

•
Lines of specialization organized, for
example, by: analytical method
(epidemiology)
setting and population (occupational
health)
substantive health problem (nutrition)
skills in assessment, policy
development, and assurance
Biologic sciences central, stimulated by
major threats to health of populations;
move between laboratory and field
Numeric sciences an essential feature of
analysis and training
Social sciences an integral part of public
health education
Clinical sciences peripheral to
professional training

Lines of specialization organized, for
example, by:
organ system (cardiology)
patient group (pediatrics)
etiology, pathophysiology
(oncology, infectious disease)
technical skill (radiology)
Biologic sciences central, stimulated by
needs of patients; move between
laboratory and bedside
Numeric sciences increasing in
prominence, though still a relatively
minor part of training
Social sciences tend to be an elective
part of medical education
Clinical sciences an essential part of
professional training

Three Core Functions of Public
Health
• Assessment
• Policy Development
• Assurance
• This is the IOM Model as identified in 1988
that lead to the Essential Public Health
Services.
Assessment
The Process of Understanding
– Population Health Status
– Threats to Health
– Community Health Resources

Policy Development
•
Reduce the threats to health
•
Support positive resources
•
Reduce disease
•
Advance overall community health
Assurance
The process of assuring:
•
Availability
•
•
Accessibility
Quality

Public health agencies are a lot like fire
departments. They teach and practice
prevention at the same time they
maintain readiness to take on
emergencies. They are most
successful—and least noticed—when
their prevention measures work the
best.

Public Health System
A public health system includes: All public, private, and
voluntary entities that contribute to the delivery of
public health services within a jurisdiction.
A public health system is: A network of
entities with differing roles,
relationships, and interactions.
All entities contribute to the health and
well-being of the community.
CDC, 2001
Public Health Infrastructure
• “The backbone of the public health system”
• Resources and relationships necessary to carry out
the core functions and essential services of public
health
• Resources:
– Human: continuing education, leadership development,
certificate programs
– Informational: online data, integrate informational
systems, research
– Organizational: expanded partnerships, statutes, core
functions funding, statewide umbrella
– Financial: to finance all of the above

Health
Public health efforts have
increased the average life
span by nearly 30 years
during the past century.
Behavioral and environmental
risk factors – smoking, poor diet,
lack of exercise, increased
pollution, stress and unsafe
sexual practices – have replaced
infectious disease as the leading
causes of premature death.
How Does Public Health Work?
• Public health address health concerns
through the application of:
– Health promotion and disease prevention
technologies and interventions designed to
improve and enhance quality of life
*These methods encompass a broad range of activities,
but are all grouped under 3 main core public health
functions.
