field epidemiology meaning

The following is an example of a investigation that is typical of the sort of issues that we face. Despite continuing changes in the contexts within which epidemiologists operate, as well as the types and quantity of information that epidemiologists have at their disposal, the core principles of field epidemiology remain largely constant. Similar collaborations exist at the federal level (21). This, however, is at odds with the current trend of major internet … The anthrax attacks during fall 2001 and related concerns about bioterrorism have stimulated other advanced and carefully designed legal measures to facilitate joint epidemiologic and criminal investigations. Field investigations often use information abstracted from different sources, such as hospital, outpatient medical, or school health records. Portions of this chapter as incorporated within previous editions of this book were adapted from Goodman RA, Buehler JW, Koplan JP. Focus on diseases and conditions, as well as research methods, specific to older populations; Local expertise includes researchers involved in studying the epidemiology of cognitive decline, dementia, Parkinson’s disease, depression, age-related macular degeneration, musculoskeletal disorders, frailty, osteoporosis, urinary incontinence, successful aging, and others. For example, consider the following scenario: At 8:30 am on Monday, August 2, 1976, Dr. Robert B. Craven, an Epidemic Intelligence Service (EIS) officer assigned to the Center for Disease Control’s (CDC) Viral Diseases Division, received a telephone call from a nurse at a veterans’ hospital in Philadelphia, Pennsylvania. Phylogenetic analyses of target genes within the human immunodeficiency and hepatitis C viruses enabled epidemiologists to retrospectively determine and intervene in the link between specific outbreak strains and local needle-sharing networks using contaminated equipment (29). Experiences during 2014–2016 with the Ebola virus disease (EVD) outbreak in West Africa underscore how networks of professionals trained in the basics of field epidemiology can play key roles in mitigating the health and economic effects of emerging disease threats, such as EVD. The nurse reported two cases of severe respiratory illness (including one death) in persons who had attended the recent American Legion Convention in Philadelphia. Field investigations are sometimes perceived to represent what is sometimes called “quick and dirty” epidemiology. For example, as part of the measles elimination effort in the United States, a measles outbreak is defined as a chain of transmission including three or more cases linked in time and space (6). The diagnoses of individual illnesses that might be associated with bioterrorism also should prompt investigations, at least to the point of dismissing concerns that exposure resulted from an intentional act. Acute disease outbreaks often generate considerable local attention and publicity. You will be subject to the destination website's privacy policy when you follow the link. 2. Epidemiology is the study (scientific, systematic, data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (patient is community, individuals viewed collectively), and the application of (since epidemiology is a discipline within public health) this study to the control of health problems. The goal should be to maximize the scientific quality of the field investigation in the face of the full range of limitations, pressures, and responsibilities imposed on the investigator(s). Relies on a systematic approach to gather and organize data in a way that will support a better understanding of a disease situation 22. Definition: Epidemiologie Die Epidemiologie ist der Teilbereich der medizinischen Wissenschaft, der sich mit den Ursachen, der Verbreitung und den Folgen von „Ereignissen“ (in der Regel Krankheiten) […] Examples of these developments include the following. Epidemiologists who conduct field investigations are often working in a fishbowl-type of environment. Epidemiology is a field where trained epidemiologists study patterns of frequency and the causes and effects of diseases in human populations. The increasing use of social media and email can facilitate outreach to and queries of persons who might have common exposures in an outbreak situation, such as participants in an organized event linked to a common-source exposure.
