    1. Epidemiology: A Basic Public Health Science Session 1, Part 1

    2. E is for Epi Series Overview • Designed for non-epidemiologists • Provides introduction to: • History of epidemiology • Epidemiology specialties • Key terminology, measures, and resources • Describes examples of epidemiology in public health practice

    3. Learning ObjectivesSession 1, Part 1 • Define the 10 Essential Public Health Services • Explain the science of epidemiology in the broader context of the ten Essential Public Health Services

    4. OverviewSession 1, Part 1 • “Quiz” • The 10 Public Health Essential Services

    5. Quiz

    6. Scenario As you read the front page of the local paper, you notice an alarming article about an outbreak of “disease X” in your community. You read on to learn about the scientifically established cause of “disease X,” and precautionary measures for avoiding exposure.

    7. Question 1 This valuable information was published as a front-page story because: • The local football team lost its game last night • The front-page columnist is on vacation • State and local health officials and their staff have worked for weeks to gather data, conduct laboratory and statistical tests, generate hypotheses, and collaborate with the media to alert and educate the public about “disease X” as effectively as possible

    9. Scenario 2 On your way into the local grocery store, you notice a flyer advertising a toll-free hotline number for enrolling uninsured children in a federally funded health insurance program.

    10. Question 2 This insurance program is being offered because: • The federal government has a budget surplus and is looking for a way to spend it • A telephone company offered the state health department a great deal on 1-800 numbers • Public health professionals have documented the numbers of uninsured children in their states, and worked with federal and state policy makers to institute outreach and “wrap around services” that assure the universal provision of health care

    28. #9: Evaluate effectiveness, accessibility, and quality of personal and population-based health services • Evaluation and critical review of health programs • based on analyses of health status and service utilization data • to determine program effectiveness • to provide information for allocating resources and reshaping programs

    29. #10: Research for new insights and innovative solutions to health problems • Link with institutions of higher learning and research • Mount timely epidemiological and economic analyses • Conduct needed health services research • Survey design; conducting interviews and facilitating focus groups • Conducting clinical trials • Accessing and using public records

    31. Summary • Core Functions of public health are assessment, policy development, and assurance • The 10 Essential Public Health Services create a “common ground” and a comprehensive infrastructure that provides a supportive context for any public health priority in a community • Epidemiology is a quantitative tool that can be used to implement Essential Public Health services
