Epidemiology is the method used
to find the causes of health outcomes and diseases in populations
. In epidemiology, the patient is the community and individuals are viewed collectively.
What is descriptive epidemiology and why is it important for public health?
Descriptive epidemiology provides a way of organizing and analyzing data on health and disease in order to understand variations in disease frequency geographically and over time and how disease varies among people based on a host of personal characteristics (person, place, and time).
What is the purpose of epidemiology?
It is the scientific method of investigation problem-solving used by disease detectives— epidemiologists, laboratory scientists, statisticians, physicians and other health care providers, and public health professionals—
to get to the root of health problems and outbreaks in a community
.
What are the uses of epidemiology?
For community diagnosis of the presence, nature and distribution of health and disease among the population, and the dimensions of these in incidence, prevalence, and mortality; taking into account that society is changing and health problems are changing. To study the workings of health services.
How do epidemiologists determine the cause of an epidemic CDC?
Epidemiologists count cases of disease (or injury), consider the distribution of the cases, and define the affected population. If a problem is identified, they
use data they collect to try to determine its cause and how it is being transmitted
. They also recommend how best to control its spread within the population.
How does epidemiology affect healthcare?
Epidemiology is a discipline that has a crucial role in
describing health status, identifying risk factors, and analyzing relationships between health and different hazardous agents
. The classical epidemiological triangle of host-agent-environment describes how individuals become ill.
Why is epidemiology useful in nursing?
Conclusion:
Epidemiological studies can potentially offer considerable benefits to the way nurses incorporate health-related practices into their professional role
. Research also offers a valuable opportunity for the nursing profession to become more active in helping to determine health policy issues.
Why is epidemiology important to environmental health?
Environmental epidemiology is one of the most important tools used in environmental management decision making owing to
its capacity to assess and monitor environmental hazards in different settings and quantify their health impact on the population at risk
.
Epidemiology and community health is
the wide scope which covers the epidemic and infectious diseases affecting certain area or community’s health
. This not only covers their occurrence and spread but also concentrates on recurrence and prevention methods to be taken.
What are the most common uses of epidemiology?
- To study the disease trend since past.
- Community diagnosis.
- Planning and evaluation of health services.
- Evaluation of a new therapy or a new health measure.
- Determining the risk to an individual.
- Identification of syndromes.
- Filling in the gaps in the natural history of the disease.
What ways might epidemiologists assist in keeping the public safe from disease?
coordinating surveillance and reporting systems across governmental boundaries, supporting the adoption and use of new surveillance techniques, assessing the preparedness of health care providers to identify and report on emerging infections at the local level, and.
How does an epidemiologist work?
When disease outbreaks or other threats emerge, epidemiologists are on the scene to investigate. Often called “Disease Detectives”, epidemiologists
search for the cause of disease, identify people who are at risk, determine how to control or stop the spread or prevent it from happening again
.
Where do epidemiologists typically work?
Epidemiologists typically work
in offices and laboratories at health departments for state and local governments, in hospitals, and at colleges and universities
. Epidemiologists are also employed in the federal government by agencies such as the Centers for Disease Control and Prevention (CDC).
How do community public health nurses use epidemiology in their practice?
Community health nurses use epidemiological concepts
to improve the health of population groups by identifying risk factors and optimal approaches that reduce disease risk
.
What are the five core functions of epidemiology?
In the mid-1980s, five major tasks of epidemiology in public health practice were identified:
public health surveillance, field investigation, analytic studies, evaluation, and linkages
.
What is environmental health epidemiology?
Environmental epidemiology is
the study of the distribution and environmental determinants of disease
. This observational science relies upon events occurring within human populations, so-called natural experiments, from which inference is drawn to identify causes of disease.
