2. Public Perceptions of Public Health (or, What the Person in the Street Thinks Public Health Is?) General ignorance (no clue); “I don’t know, I never thought about it.”
“Abstract;” hard to pin down or define
Surrounded by uncertainty and confusion (“well….ummmm, I’m not sure”)
Vague/obtuse understanding (oh, well, “it’s the health of the public”)
Considered simply another branch of medicine
3. When Does Public Health Come to the Forefront? Seldom, when it is working or doing what is supposed to; typically, it is simply assumed; going unnoticed or appearing to be “invisible” most of the time... EXCEPT
When its absence is recognized when there is a problem
When a crisis is at hand
When “the system” seems to fail

8. CEA Winslow’s “Classic” Definition of Public Health, 1920 (expanded version) “… the science and art of preventing disease. Prolonging life and promoting health and efficiency through organized community effort
for the sanitation of the environment,
the control of communicable infections,
the education of the individual in personal hygiene,
the organization of medical and nursing services for the early diagnosis and preventive treatment of disease, and for
the development of the social machinery to ensure everyone a standard of living adequate for the maintenance of health,
so organizing these benefits as to enable every citizen to realize his birthright of health and longevity.”
9. John Last’s Definition of Public Health, 1980 “… efforts organized by society to protect, promote, and restore the people’s health … combination of sciences, skills, and beliefs directed to maintenance and improvement of health of all people through collective or social actions … emphasis on prevention of disease … activities change with changing technology & social values, but goals remain the same.”

15. Identified “Themes” Associated with Public Health Issues Uneasy tension between science and politics, and practice?
What should the role of government be in public health?
Newly emerging concern: preparedness
The role (and use) of incentives in public health
Integral connection between environmental issues and public health
Public health is global in nature (e.g., communicable disease transmission/travel; global warming), and broad in scope
Ethical issues arise in conducting public health research –
do the subjects of research also reap the benefits/rewards;
should U.S. standards (protections) apply universally in other (developing) nations
Risks?
Risks associated with pandemic flu; avian flu
Risks associated with HIV/AIDS
Vaccinations/immunizations
The “Tragedy of the Commons”
16. Public Health Fundamentals 5 Ps of Public Health (expansion from the 3 Ps)
Prevention (individual and community-focused)
Promotion (voluntary, education, advocacy)
Protection (policies/regulations; enforcement)
Population-based (communities, groups)
New 5th P: Preparedness (e.g., bioterrorism, natural disasters, pandemics)
Closely linked to Environmental Health
17. Major Eras in U.S. Public Health History Prior to 1850 Influence of superstition, religion, miasma theory; battling epidemics/pandemics: avoidance and acceptance;
advent of bacteriological era
1850-1949 Sanitary reform through state and local infrastructure (state and local health departments); development of public health infrastructure
1950-1999 Filling gaps in medical care and expanding the health agenda; Major advances in medicine; AIDS; control of infectious disease, growth of chronic disease (largely behaviorally-related)
2000- Community public health practice; evolving public health infrastructure development; preparing for and responding to community
health threats
18. The Future of Public Health – IOM Selected Findings “The current state of our abilities for effective public health action… is cause for national concern and for the development of a plan of action for needed improvement … we have slackened our public health vigilance nationally, and the health of the public is unnecessarily threatened as a result.”
Clearly defined public health is basic terms
Stated that neither the general public or policymakers understood public health or its importance
Urged those working in public health to reach out to educate the public about what public health is

19. IOM Selected Findings - 2 Throughout the history of public health, two major factors have determined how problems were solved:
1. The level of scientific and technical knowledge
2. The content of public values and popular opinions (and ultimately political will)
Overtime, public health measures have changed with important advances in understanding the causes and control of disease (i.e., epidemiology)
Public health practices have been affected by:
1. popular beliefs about illness and
2. by public views of appropriate governmental action
20. IOM Selected Findings - 3 As poverty and disease came to be seen as both a societal as well as a personal problem, and as governmental involvement in societal concerns increased, collective action against disease became gradually accepted… Health became a social as well as an individual responsibility.
21. Selected Findings - 4 Knowledge and values today remain decisive elements in the shaping of public health practice… but they blend less harmoniously than they once did. On the surface, there appears to be widespread agreement on the overall mission of public health, as reflected in comments heard by the Committee…
Public health does things that benefit everybody
Public health prevents illness and educates the population
22. Selected Findings - 5 But, when it comes to translating broad statements into effective action, little consensus can be found…
There is little agreement as to what services should be provided or to what intensity they should be provided (in some states the state health department was a major provider of prenatal care for poor women; in another, women who could not pay got no care).
Some state health departments are active and well equipped and funded; others perform minimal functions and have little support
In some states, there are large and sophisticated local health departments; in many localities, there is no health department
23. IOM’s Three Basic Recommendations The mission of public health
The government role in fulfilling the mission
The responsibilities unique to each level of government
Other recommendations made by the committee were instrumental in implementing the basic recommendations for the future of public health, e.g., statutory frameworks, structural and organization steps, strategies to build the fundamental capacities of public health agencies – technical, political, managerial, programmatic, fiscal, educational
24. 1. The Mission of Public Health Fulfilling society’s interest in assuring conditions in which people can be healthy.
Generate organized community effort to address the public interest in health by applying scientific and technical knowledge to prevent disease and promote health
The mission is addressed by both private organizations and individuals as well as by public agencies
Unique function of the governmental public health agency: to see that vital elements are in place and that the mission is adequately addressed
25. 2. The Governmental Role in Public Health The “core functions” of governmental agencies at ALL levels of government are (a) assessment, (b) policy development, and
(c) assurance.
a. What is Assessment?
Every public health agency regularly and systematically collect,
assemble, analyze, and make sensible information on the health
of the community, including statistics on health status, community
health needs, and epidemiologic and other studies of health
problems
26. 2. The Governmental Role in Public Health (continued) b. What is Policy Development?
Every public health agency has the responsibility t oserve the public interest in the development of comprehensive public health policies (a) by promoting use of its scientific knowledge base in decision making about public health and (b) by leading in the development of public health policy. Agencies must take a strategic approach, developed on the basis of a positive appreciation for the democratic political process.
c. What is Assurance?
Public health agencies must assure their constituents that services necessary to achieve agreed upon goals are provided, either by encouraging actions by other entities (private or public), by requiring such action through regulation, or by providing services directly.
27. 3. Levels of Responsibility Each level of government bears its unique set of responsibilities.
a. States
Must be the central force in public health, playing the primary public sector responsibility for health.
State duties should include:
Assessing state health needs; statewide data collection
Assuring an adequate state statutory base for health activities
Establishing statewide health objectives, delegating power to localities as appropriate and hold them accountable
Assuring an organized statewide effort to develop and maintain essential personnel, educational, and environmental health services, provision of access to necessary services, and solving health-related problems
Guaranteeing a minimum set of essential health services
Supporting local service capacity, particularly when disparities exist
28. 3. Levels of Responsibility (continued) b. Federal
The following were viewed as federal public health obligations.
Support of knowledge development and dissemination through data gathering, research, and information exchange
Establishing nationwide health objectives and priorities, and stimulating debate on interstate and national public health issues
Providing technical assistance to help states and localities determine their own objectives and to carry out action on national and regional objectives
Providing funds to states to strengthen state capacity for service, especially to achieve an adequate minimum capacity, and to achieve national objectives
Assurance of actions and services that are in the public interest of the entire nation such as control of AIDS and similar communicable diseases, interstate environmental actions, and food and drug inspection
29. 3. Levels of Responsibility (continued) c. Localities
Because of the great diversity in size, powers, and capacities of local governments, generalizations must be made with caution. Nevertheless, no citizen from any community, no matter how small or remote, should be without identifiable and realistic access to the benefits of public health protection, which is possible only through a local component of the public health delivery system
Assessment, monitoring, and surveillance of local health problems and needs and of resources for dealing with them
Policy development and leadership that foster local involvement and a sense of ownership, that emphasize local needs, and that advocate equitable distribution of public resources and complementary private activities
Assurance that high quality services, including personal health services, needed for the protection of public health in the community are available ans accessible to all persons; that the community receives proper consideration in the allocation of federal and state public health funds, and that the community is informed about how to obtain public health services or to comply with public heath requirements
30. What (Who) Comprise Public Health? Broad and interdisciplinary in nature
Epidemiologists and biostatisticians
Biomedical scientists (e.g., biologists, microbiologists, bacteriologists, virologists, chemists, physicians)
Environmental health specialists (including environmental health specialists, toxicologists, sanitarians)
Social and behavioral scientists (e.g., health educators, psychologists, social workers)
Health policy makers and administrators (e.g., administrators, elected officials, program managers)
“Non-public health” professionals who are involved in public health activities and programs (e.g., engineers, lawyers, nutritionists, teachers)
Other workers and occupations whose “work” constitutes activities that protect and promote the public health, but who never think of themselves as playing a role in public health (e.g., plumbers, rubbish collectors, contractors)
In sum, people practicing skills aimed at protecting and promoting the health of the public
32. Dimensions of the Public Health System Capacity (Inputs): the resources and relationships necessary to carry out the core functions and essential services of public health (e.g., human resources, information resources, fiscal and physical resources, and appropriate relationships among system components).
Processes (Practices and Outputs): those collective practices or processes that are necessary and sufficient to assure that the core functions and essential services of public health are being carried out effectively (including the key processes that identify and address health problems and their causative factors and the interventions intended to prevent death, disease, disability, and to promote quality of life).
Outcomes (Results): indicators of health status, risk reduction, and quality of life enhancement outcomes are long-term objectives that define optimal, measurable future levels of health status; maximum acceptable levels of disease, injury, or dysfunction; or prevalence of risk factors.

36. Levels of Disease Prevention Primary Prevention: activities intended to prevent future onset of disease, e.g., immunizations, seatbelt use, avoidance of tobacco, reduced alcohol consumption, “safe sex,” exercise, air pollution control, restaurant inspections, health education programs
Secondary Prevention: early detection of health problems/disease, to promote further recommended testing and the early intervention of treatment or the risk that communicable diseases transmission to others, e.g., hypertension screening, cholesterol screening, HIV/STD testing, mammograms, pap smears, colonoscopies.
Tertiary Prevention: rehabilitation activities designed to prevent subsequent worsening or reoccurrence of disease, disability, or injury, e.g., cardiac rehab, adhering to strict dietary restrictions, re-learning to walk after an orthopedic injury or stroke.
37. Health Promotion and Disease Prevention Encompasses a Broad Array of Functions and Expertise Assess and monitor the health of communities and populations at risk to identify health problems and priorities
In collaboration with community and government leaders, formulate public policies to solve identified local, state, and national problems and priorities
Assure that all populations have access to appropriate, effective, and cost-effective health promotion and disease prevention services
38. A Day in Your Life with Public Health An Exercise In thinking about your activities that typically occur on a daily basis, let’s try to make a list of how public health touches or impacts you (i.e., the ways in which you interface with public health)...
Let’s add to the list events or activities that you periodically encounter but not necessarily on a daily, or even weekly, basis …
Think practically and creatively …
From the moment you arise in the morning, e.g., 6:30am
Going to work or to school, e.g., 8:00am
Mid-day, e.g., noon
End of the work day or school day, e.g., 4:30pm
Evening, e.g., 6:00pm
Retiring for the night, 11:00pm
39. A Day in Your Life with Public Health In reviewing the above list(s), what do you realize?
What does this illustrate to you?
