(Epidemiologic)
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 control health problems. It aims to understand the patterns of disease occurrence, risk factors, and the impact of interventions on public health. Epidemiologists use various methods, including surveillance, observational studies, and clinical trials, to gather data and analyze trends in disease spread.
By examining factors such as demographics, behavior, genetics, and environmental exposures, epidemiologists identify patterns of disease occurrence and risk factors within populations. This information is crucial for designing effective public health interventions, such as vaccination campaigns, health education programs, and policy changes.
Epidemiology plays a vital role in disease prevention and control, outbreak investigation, and health policy development. It helps identify populations at risk, assess the effectiveness of interventions, and inform evidence-based decision-making in healthcare and public health. Ultimately, epidemiologic research contributes to improving the health and well-being of communities worldwide by understanding and addressing the factors that influence health outcomes.
1- How does the epidemiologic triad apply to health issues we see in the hospital? What are some common diagnoses in the acute care setting? What about in the community setting? How does the epidemiologic triad differ when a nurse is providing care to someone in the community or in his home? Does the nurse have more or less control in either arena?
2- Discuss the data presented regarding obesity in America in the Ethical Connection feature on page 118. Please review the data and discuss your feelings about the role of community health nurses in community nutrition.
3- What are some of the causes for increases in healthcare costs in recent years, as outlined in the chapter? Brainstorm some examples that you have actually witnessed in the clinical setting. Can any of these factors be modified? What could nurses do to help cut down on costs related to the different factors?
4- Why are the causes of morbidity and mortality in other countries different than in the United States? In what ways are they the same? Why do those differences exist? What types of services & interventions are needed in less developed countries to help with their health issues?
