What are the uses of epidemiology Rating:
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. It is a crucial branch of public health that deals with the incidence, distribution, and control of diseases and other health conditions in populations.
There are many uses of epidemiology in public health and medicine. Some of the key uses are:
Surveillance: Epidemiology is used to monitor the occurrence of diseases and other health conditions in a population. This helps public health officials to identify trends and patterns in the distribution of diseases, and to determine the risk factors associated with these diseases.
Disease control and prevention: Epidemiology is used to design and implement strategies to control and prevent the spread of diseases in populations. This can include vaccination programs, education campaigns, and the implementation of public health policies.
Research: Epidemiology is used to conduct research on the causes and risk factors of diseases. This helps to identify the factors that contribute to the development and progression of diseases, and to develop interventions to prevent or treat these conditions.
Health policy development: Epidemiology is used to inform the development of health policies at the local, national, and international levels. It helps policymakers to understand the health needs and priorities of different populations, and to design policies that address these needs.
Clinical practice: Epidemiology is used in clinical practice to guide the diagnosis and treatment of diseases. It helps healthcare providers to understand the prevalence and incidence of different diseases in a population, and to tailor their treatment approaches accordingly.
Overall, epidemiology plays a vital role in public health and medicine. It helps to identify and understand the distribution and determinants of health-related states or events in populations, and to design and implement strategies to control and prevent the spread of diseases.
This way, researchers can prevent the event from happening in the future. Also, the knowledge of the risk factors involved in epidemiology is used to direct further research investigation and to implement disease control measures. Population studies—of people's needs for health care and their demands for it—were said to be required. The prospective study of cohorts, the combination of survey with case studies, international comparisons and field experiments are being increasingly used. It was found that there was a large group of people visiting the same restaurant for more than four weeks.
It searches for diseases amongst a larger population. Taken from Morris JN, Uses of Epidemiology. In the third edition of Uses, Morris recognized that there was no better theory for peptic ulcer than stress hypotheses at the time, but was clearly very dissatisfied with these. His kind of epidemiology, an almost moral duty to observe the impact on the people's health of contemporary social customs and movements—the central intelligence behind all public health-work shines out from the pages of Uses of Epidemiology as a very modern inspiration. At times, a disease can be stationary and arrested. From the analysis and reports guide the public health system accordingly on intervention.
What Can I Do With a Degree in Epidemiology? Epidemiology is a study and analysis of the distribution, patterns, and determinants of health and disease conditions in defined populations or how often diseases occur in different groups of people and why. Uses of Epidemiology, whose main arguments were summarized in a paper published in the British Medical Journal 2 years earlier reprinted in this volume , 2 represented the flowering of a substantial and visionary post-war social medicine project. Early stakeholder involvement is crucial in identifying who will carry out which elements of the assessment, and ensuring engagement of all parties. Source: Davey Smith et al. ADVERTISEMENTS: Earlier the term epidemiology was referred to only those communicable diseases which used to spread in epidemic form like small-pox, cholera, plague etc. Production processes that can make the finished product to be dangerous and plans measures to reduce these perils to a safe level in public health.
Figure 1 The Dahlgren and Whitehead model The statutory duty of Joint Strategic Needs Assessment, which will be undertaken by local authorities and clinical commissioning groups CCGs , through the health and wellbeing board, is an opportunity to examine these wider determinants of health as part of a broad assessment of local needs. The book appeared at a time when epidemiology was undergoing a fundamental change. This approach considers the epidemiology of the condition, current service provision, and the effectiveness and cost-effectiveness of interventions and services. The scope of epidemiology tracks how far the disease spread. However, for the 13 specific cancer sites examined grade-related risk varied by site. Since the aims of epidemiology go so far and wide, you can look for jobs in all kinds of places. Furthermore, much of the material in the chapters regarding the other uses of epidemiology refers to how they can contribute to understanding the causes of disease.
Elements of the corporate approach i. If you become a field epidemiologist, you can travel and treat effected populations directly. A wide range of health problems is studied using both cohort and case-control studies. The objective of epidemiology is to figure out what causes different health outcomes in different groups of people. Individual and group risks There has been considerable recent interest in the concept that groups possess properties over and above the sum of the properties of individuals, and that these may influence disease risk. To study the workings of health services in the community C.
Chapter 1 (History, Philosophy, and Uses of Epidemiology) Flashcards
From: The epidemiological approach to health care needs assessment. To diagnosis the dimensions and distributions of disease within a community B. First published BMJ 1955;2:395-401. Items a are for samples of the total bclerical workers in social class III are included with classes I and II for family budget only. It is important to distinguish between the need for health, and the need for health care. The associations seen at an individual level in prospective epidemiological studies can be considered with respect to the historical and geographical trends in disease, as advocated by Jerry Morris. This helps the team to work efficiently and go through the work history seamlessly.
Disease status and exposure are accessed in both the subjects. Similar findings with respect to the heterogeneity of site-specific cancer risk with socioeconomic position have come from other studies. Despite the incursions of people such as William Farr and John Snow into the murky provenance of vital statistics, the promise of ecological studies of disease, clinical medicine and the infant study of health and illness in their social context were firmly divided occupations until the 1940s in Britain. Sex- and cause-specific correlations of adult mortality with infant mortality in one period adjusted for infant mortality in the other period. All of the uses of epidemiology involve these five questions. Where: Epidemiologists ask where the disease or event orginated. This approach is based on eliciting the views of stakeholders - which may include professionals, patients and service-users, the public and politicians - on what services are needed.
This begins with the determination of needs and resources, proceeds to analysis of services in action and, finally, attempts to appraise. This may involve collection of both quantitative and qualitative data, which are then analysed to give a detailed picture of health needs. How many children are immunized against diphtheria or smallpox? Doctors practiced medicine, and other people social workers? Uses of Epidemiology draws on the research Morris and Titmuss did which produced three classic papers on juvenile rheumatism, 7 rheumatic heart disease 8 and peptic ulcer. Research in this tradition existed before the mid-century—for example in 1930 RA Bolt published a study relating public health expenditure to infant mortality rates across cities in the US. Its major study areas include disease causation, transmission, outbreak investigation, and disease surveillance.
