7. Discuss the three core functions of public health and their ethical tenants.
Definitions
Epidemiology: the study of the distribution and factors that determine health-related states or events in a population, and the use of this information to control health problems.
- Descriptive epidemiology
- Distribution of disease according to person, place, time
- For example: What is the disease? Who is affected? Where are they? When do events occur?
- Analytic epidemiology
- Determinants of the patterns
- For example: How does it occur? Why are some people affected more than others?
Types of Epidemiology
Descriptive
- Person (who)
- Place (where)
- Time (when)
- Secular trends
- Point epidemic
- Cyclical patterns
Analytic
- Seeks to discover the determinants of outcomes
- How? Why?
- Cohort studies
- Case-control studies
- Cross-sectional studies
History
- Ancient Greece
- Hippocrates
- Modern epidemiology emerged in the 19th century.
- John Snow, “father of epidemiology”
- Twentieth century
- Dramatic changes in life expectancy
- Increase in chronic diseases-ecologic model
Epidemiologic Triangle
Measures of Morbidity and Mortality
Proportions
- type of ratio in which the denominator includes the numerator; often expressed as a percent.
- Example: In 2006, there were 2,426, 264 deaths recorded in the US of which 631, 636 were caused by heart disease. Therefore, 631, 636/2426,264=0.260 or 26%
- The proportion may be expressed as a number per 1000 or 100,000
a measure of the frequency of a health event, how rapidly something is happening.
- The denominator serves as the # of individuals in the population during the year that change occurred
- Rates are commonly expressed as per 100, 000 or per 1,000
- Example: In 2006, the U.S. population was 299, 398, 484/100,000=2993.98484. The death rate from heart disease in 2006 would be 631, 636/2993.98484=211 per 100,000
- Covid 19 positivity rates
- Higher positivity rates = increased restrictions/policy enforcement
Rate
- Refers to the probability that an event will occur within a specified time period
- The measures of morbidity (incidence and prevalence) provide information about the risk and rates of disease presence and development
Risk
- Quantifies the rate of development of new cases in a population at risk
- Existing (prevalent) cases are excluded from the population at risk
- Example:
- Over 5-year period, 20 of 200 individuals were newly diagnosed with cancer. The incidence proportion would be 20/200 = 0.10 or 10% so over a 5-year period the risk of cancer in the population was 10%
Incidence
- Measure of existing disease in a population at a particular time (i.e., the number of existing cases divided by the current population)
- Not an estimate of the risk of developing disease!
- Example: Breast cancer screening of 8000. 35 women were previously diagnosed and additional 20 cases of breast cancer were identified through screening. 55 out of 8000 expressed as rate of 687.5 per 100,000.
Prevalence
Attack Rate and Mortality Rate
- Attack rate
- defined as the proportion of persons who are exposed to an agent and develop the disease; is often specific to an exposure.
- Form of incidence proportion
- Example: food borne illnesses
- Mortality rates
- informative only for fatal diseases
- do not provide direct information about either the level of existing disease in the population or the risk of contracting any particular disease
- Examples: Table 9-2.
Sources of Data
- Routinely collected data
- Data collected for other purposes
- Epidemiologic data
- CDC Surveys
- National Center for Health Statistics Surveys
Applications of Epidemiology in Nursing
Nurses use epidemiologic frameworks, methods, and data to better understand factors that contribute to:
- Health and disease
- Health promotion and disease prevention interventions and measures
- Identifying the presence of infectious agents in individuals and groups
- Community health programs
- Public health policies
Public Health Interventions: Surveillance
“The ongoing systematic collection, analysis, and interpretation of health data related to the occurrence of disease and the health status of a given population for the purpose of planning, implementing, and evaluating public health interventions” (Keller and Strohschein, 2001)
- Purpose of Surveillance
- The Investigation
- Defining the magnitude of a problem/event
- Endemic
- Epidemic/Outbreak
- Pandemic
- Identify Patterns of Occurrence
- When to Investigate

Data Sources for Surveillance
- Cases reported by clinicians, health care agencies, and laboratories to state health departments
- National Notifiable Diseases
- State Notifiable Diseases
- (Box 17.3 p 310)
- Death certificates
- Administrative data (i.e., billing)
- Sentinel surveillance system
Types of Surveillance Systems
- Passive system
- Active system
- Sentinel system
Collaborative Learning:
Syndromic surveillance: “surveillance using health-related data that precede diagnosis and signal a sufficient probability of a case or an outbreak to warrant further public health response” (CDC, 2017) Use the links below to address the following questions:
- How does the EHR impact surveillance?
- Share examples of syndromic surveillance software in action
Interventions and Protection
- Response to bioterrorism or large-scale infectious disease outbreak
- Protecting health care providers from exposure
- Look to evidence-based practice guidelines!
Ethics and the Core Functions of Public Health Nursing: Assessment
Competency related to knowledge development, analysis, and dissemination
Virtue ethics or moral character/Integrity “Do good” and “Do no harm”
Beneficence and Non-maleficence
Ethics and the Core Functions of Public Health Nursing:Policy Development
Achieve the public good
•Rooted in citizenship
Service to others over self (a necessary condition)
•Serve rather than steer•Serve citizens, not customers•Value citizenship and public service above entrepreneurship
What is ethical is also good policy
Ethics and the Core Functions of Public Health Nursing: Assurance
All persons should receive essential personal health services.
Providers of public health services are competent and available.
•Healthy People 2030 objectives
•Social justice/Distributive Justice (fair allocation of resources
Note: A review from NURS 360 has been provided to you in the student powerpoint. Understand public health interventions to be evidence based with an emphasis on meta-analysis and systematic reviews. The higher the level of evidence the lower the bias; VERY important when designing and implementing interventions with large groups! Refer to your existing knowledge and resources from NURS 360 and plan to APPLY it during clinical. Some resources are already posted and available within NURS 444L clinical content tab on D2L.
Types of Evidence
- Double blind RCT generally ranks as the highest level of evidence
- Difficult to perform RCTs in public health
- Other sources are used
25
Steps in the Evidence-Based Practice Process
Cultivating a spirit of inquiry
Form a PICOT question
Searching for the best evidence***
Critically appraising the evidence***
Integrating evidence with clinical expertise, client preferences, and values
Evaluating outcomes of the practice decisions or changes based on evidence
Disseminating EBP results
26
Approaches to Finding Evidence
- Meta-Analysis: Method of statistical synthesis use in some systematic reviews; results from several studies are quantitatively combined
- Systematic Review: a summary of the research evidence that relates to a specific question and to the effects of an intervention.
- Example: PH Intervention Wheel
- Databases (BOX 10.2):
- Guide to Community preventive services
- Cochrane Public Health Group
- Center for Reviews and Dissemination
- Campbell Collaboration
Approaches to Evaluating Evidence
- Grading the strength of evidence
- Identify criteria used to assess level, quality, strength of evidence. There are many frameworks to use. Strength is based on 3 things:
- Quality
- Quantity
- Consistency
- Appraise evidence for: Patient Oriented Evidence that Matters (POEM)

Incidence, Prevalence, Morbidity, Mortality Rate
- 500,000 died from an opioid overdose (CDC, 2021)
- 1.6 million Americans had an opioid use disorder (HHS,2021)
- 10.1 million people misused prescription opioids in the past year (HHS, 2021)
- MORBIDITY
- PREVALENCE
