Describe and given an example of the Epidemiological Triangle.
<-->susceptible person or host<-->
<-->causative agent<--> <-->Environment<-->

At the center: RISK (the probability that a person will become ill)

this model is simpler than the web of causation

Ex: hepatatis A, students/staff of schools, school cafeteria strawberries
Things to consider: Host
A living species capable of being infected or affected by an agent.
demographic characteristics
level of health
history of prior disease
genetic predisposition
state of immunity
body defenses
human behavior/lifestyle

Ex: human being
Things to consider: Causative Agent
presence or absence of biologic, physical, chemical, nutritional, genetic, or psychological factors that have the ability to affect the host's health
Ex: virus, bacteria, lead, pesticides, cold, heat, radiation
Things to consider: Environment
anything external to the host or agent, including presence of other people or animals. Influences and is influenced by the host and/or agent.
Ex: climate, peers, socioeconomic, work environment
Levels of Prevention (p. 156 graphic)
primary - altering susceptibility/reducing exposure
secondary - early detection/prompt treatment
tertiary - limiting disability/rehabilitation
What is epidemiology?
The study or investigation of the distribution or the patterns of health events in populations and the determinants or the factors that influence those patterns.
*Descriptive: Who, What, Where, When
*Analytic: How, Why

Focuses on POPULATIONS
Healthy People 2010 addresses...
the need for epidemiological services and the use of data - 28 areas of focus were identified for data collection.
Who was the father of epidemiology?
John Snow - developed a mapping of the cholera epidemic and pinpointed contaminated water source.
Epidemiology has become a basis for nursing practice...
nurses use data from genetics, emerging infections, environmental toxins, behavioral and social factors to look at health and disease causation for treatment/prevention interventions.
Sources of epidemiological data
(sources of health/disease indicators)
secondary: vital statistics, surveillance data (reportable diseases), medical records, insurance records, census data

Primary:
interviews, focus groups, surveys
Rates

(help to determine risk)
the measure of frequency of health events in a defined population during a specified period of time, taking into account the size of the population
Ex: Rate per 1000
500 cases/15,000 people

500/15000 = x/1000

= 33/1000
Measures of Morbidity:
Prevalence Rate
total number of new cases and old cases of a disease or health conditon
Measures of Morbidity:
Incidence Rate
total number of new cases of a disease or health condition over time
Measures of Morbidity:
Attack Rate
The proprtion of people who are exposed to an agency and the number of people who acquire the disease.
Mortality Rates
Death Rate
reported as per 1000, per 10,000 or per 100,000
TYPES:
age-specific
cause specific
infant
neonatal
Rates and ratios:
statistics used to describe births, deaths and incidencses and prevalences of disease and disability in populations.
Person
includes personal characteristics observed in populations
race, gender, age, education level, socoeconomic.
Disparities in mortality rates related to these factors. Age is #1.
Place
do mortality and morbidity rates vary based on the geography, population density, location of vectors, healthcare accessibility, social patterns, cultural health beliefs.
Time
an increase or decrease in the frequency of disease over time.
Secular Trends
long-term patterns

Ex: seatbelt and infant mortality
Point Epidemic
time and space related pattern; important in investigate of infectious disease
Cyclical Time Patterns
Seasonal influence based upon weather, calendar events (holidays), recreational activity
Event Related Cluster
patterns where time is not measure from a fixed date but the point of exposure.
Ex: immunization adverse sign reports
Analytic Epidemiology:
Cross-sectional studies
discover determinants of outcomes, using a snapshot or cross section of the population.
Analytic Epidemiology:
ecological studies
discover determinants of outcomes,
Analytic Epidemiology:
cohort studies
discover determinants of outcomes, a group of people who are born about the same time or sharing some common characteristic
prospective: longitudinal
retrospective:historical
Analytic Epidemiology:
case-control studies
discover determinants of outcomes, study enrolls those with a condition and those without (control)

Result is an Odds Ratio
Odds Ratio
abuse 68/suicideattempt 32
X
no history36/no attempt 164

cross multiply=9.68

which represents that those with a history of abuse have 10X greater risk of suicide attempt
Interventionl studies
measures the effectiveness of a treatment or intervention to reduce risk

Ex: clinical trials
Screening
The secondary level of prevention
Screening: reliability
consistency of measurement
Ex: trait, observer, tool
Screening: validity
sensitivity and specificity
Ex: false positive/false negative

preference for retesting a false positive rather than sending someone away with a false negative
Screening: Ethical Consideration
Disclosure of what the test fully means?
A screen IS NOT a diagnostic test.
Causality
statistical association b/w the disease and the risk
*Bias - sampling, data collection, confounding factors
Criteria for causality
1. strength of association
2. consistency of findings
3. biological plausibility
4. demonstration of correct temporal sequence
5. dose-response relationship
6. specificity of the association
7. experimental evidence
Health promotion
the process of helping people enhance their well being and maximize their human potential.
Focus is on people and populations as a whole and changing behaviors to promote rather than simply avoid illness.
Goal is to enable people to exercise control over their well being and ultimately improve their health.
Combines education, organization involvement, economics, and political influences to bring changes.

Ex: make people move away from New Orleans
Disease prevention
Reducing disease causing factors such as:
demographic trends, nutrition, fitness, stress, toxic agent control, major causes of disease and risks to health.

Ex: fix the levee and clean up the flood
