I am a big fan of your work on risk communication and have been following it for years. I am currently researching best practice for communicating job layoffs, and wondered if you would apply your models to communicating bad news about jobs. For example, would this comment hold true in a job crisis? More often than not, they are already pondering what might go wrong, imagining the worst and wishing there were some way to get it out onto the table and get the facts.
Definition of Epidemiology Students of journalism are taught that a good news story, whether it be about a bank robbery, dramatic rescue, or presidential candidate's speech, must include the 5 W's: The 5 W's are the essential components of a news story because if any of the five are missing, the story is incomplete.
The same is true in characterizing epidemiologic events, whether it be an outbreak of norovirus among cruise ship passengers or the use of mammograms to detect early breast cancer. The difference is that epidemiologists tend to use synonyms for the 5 W's: The word epidemiology comes from the Greek words epi, meaning on or upon, demos, meaning people, and logos, meaning the study of.
In other words, the word epidemiology has its roots in the study of what befalls a population. Many definitions have been proposed, but the following definition captures the underlying principles and public health spirit of epidemiology: Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems 1.
Key terms in this definition reflect some of the important principles of epidemiology. Study Epidemiology is a scientific discipline with sound methods of scientific inquiry at its foundation.
Epidemiology is data-driven and relies on a systematic and unbiased approach to the collection, analysis, and interpretation of data. Basic epidemiologic methods tend to rely on careful observation and use of valid comparison groups to assess whether what was observed, such as the number of cases of disease in a particular area during a particular time period or the frequency of an exposure among persons with disease, differs from what might be expected.
However, epidemiology also draws on methods from other scientific fields, including biostatistics and informatics, with biologic, economic, social, and behavioral sciences. In fact, epidemiology is often described as the basic science of public health, and for good reason.
First, epidemiology is a quantitative discipline that relies on a working knowledge of probability, statistics, and sound research methods. Second, epidemiology is a method of causal reasoning based on developing and testing hypotheses grounded in such scientific fields as biology, behavioral sciences, physics, and ergonomics to explain health-related behaviors, states, and events.
However, epidemiology is not just a research activity but an integral component of public health, providing the foundation for directing practical and appropriate public health action based on this science and causal reasoning.
Frequency refers not only to the number of health events such as the number of cases of meningitis or diabetes in a population, but also to the relationship of that number to the size of the population.
The resulting rate allows epidemiologists to compare disease occurrence across different populations. Pattern refers to the occurrence of health-related events by time, place, and person. Time patterns may be annual, seasonal, weekly, daily, hourly, weekday versus weekend, or any other breakdown of time that may influence disease or injury occurrence.
Personal characteristics include demographic factors which may be related to risk of illness, injury, or disability such as age, sex, marital status, and socioeconomic status, as well as behaviors and environmental exposures.
Characterizing health events by time, place, and person are activities of descriptive epidemiology, discussed in more detail later in this lesson. Epidemiology is also used to search for determinants, which are the causes and other factors that influence the occurrence of disease and other health-related events.The identification of causal relationships between these exposures and outcomes is an important aspect of epidemiology.
Modern epidemiologists use informatics as a tool. Observational studies have two components, descriptive and analytical. Descriptive observations pertain to the “who, what, where and when of health-related state occurrence”.
My writing is aimed at people whose work requires them to communicate with others about risk. My goal is to help them do it better. But from time to time I receive an email or a Guestbook comment like this one, reminding me that people sometimes stumble on my website when they’re looking for help with a personal problem, not a professional one.
What is an Epidemiologist/Medical Scientist? Epidemiologists examine the causes of diseases to prevent them from transmitting and recurring, including investigating the triggers of an infection / There are dozens of epidemiological organizations, including the Society of Healthcare Epidemiology of America, the Council of State and Territorial Epidemiologists, the American College of Epidemiology, the Association for Professionals in Infection Control and Epidemiology and the .
