Trend-based analyses and geospatial analysis will use malarial demographics to help indicate the prevalence of Malaria in India and thereby indicate the efficacy of intervention methods implemented by the Government. Using three or more significant figures interferes with comparison and comprehension. Health. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); We are a team of dedicated analysts that have competent experience in data modelling, statistical tests, hypothesis testing, predictive analysis and interpretation. Washington D.C. You can review and change the way we collect information below. A rapid decrease in dengue cases follows this decrease in vector density.

Cases of leptospirosis by week of hospitalization and rainfall in Salvador, Brazil, March 10November 2, 1996. This arrangement facilitates sorting to reorganize cases by relevant characteristics. A title that includes the what, where, and when that identifies the data it introduces. Social groupings might be as compact as a household or as diffuse as a social network linked by a common interest. Furthermore, Governments application of epidemiology are also based on national-level control and management of diseases, proper allotments of finances, expenditure, check the efficacy of various health care programmes, and implementation of new policies or modify the existing one. Similar graphical presentations were also used in the report for identification of disease prevalence and factors causing them. Forest plot and effect size graphs from Meta-analyses used by pharmaceuticals in finding the efficacy of the drug-based interventions and present the change or difference in the intervention (Ganeshkumar, et. To indicate numeric intensity, use increasing intensity of gray from white to black. Home > Nursing homework help. Epidemiologic statistics, tables, graphs, and maps are produced with simple commands such as READ, FREQ, LIST, TABLES, GRAPH, and MAP. Healthcare policy, disease prevalence and related demographics, financial capability, the efficacy of the drugs, and disease and healthcare control and management. Purposes of Descriptive Epidemiology Descriptive epidemiology Provides a systematic approach for dissecting a health problem into its component parts. Organizing data columns and rows by the magnitude of the marginal summary statistics is often helpful. 64, 2771. The rapid increase, plateau, and precipitous downslope all appeared with a salmonellosis outbreak from cheese distributed to multiple restaurants and then recalled (Figure 6.5). Use columns for most crucial data comparisons. Helps validate the eventual incrimination of causes or risk factors. Health (4 days ago) Purposes of Descriptive Epidemiology Descriptive epidemiology Provides a systematic approach for dissecting a health problem into its component parts. It helps in assessing the reason and factors behind the occurrence of a disease. Ensures that you are fully versed in the basic dimensions of a health problem. Contact diagrams are versatile tools for revealing relationships between individual cases in time. Similarly, when the incubation period is known, you can estimate a time window of exposure and identify exposures to potential causative agents during that window. However, the use of the graphs is based on the type of outcome required by the intervener. Increasing environmental temperatures accelerate the multiplication of infectious agents in an arthropod. Disease or unhealthy conditions also can be measured on a continuous scale rather than counted directly (e.g., body mass index [BMI], blood lead level, blood hemoglobin, blood sugar, or blood pressure). This count of incident cases over time in a population is called incidence. 27.10.2019. The line-listing in Table 6.1 has been sorted by days between vaccination and onset to reveal the pattern of this important timeevent association. This is often publicized in an attempt to change behavioral patterns and policymaking. For certain conditions, a description by season, month, day of the week, or even time of day can be revealing. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. The word epidemiology comes from the Greek words epi, meaning on or upon, demos, meaning people, and logos, meaning the study of. 1: Epidemiologic Factors Events, characteristics, or other definable entities that have the potential to bring about a change in a health condition or other defined outcome. This provides relevance to the Government on the efficacy of the policies implemented and thereby update the existing or create a new policy. Provides a systematic approach for dissecting a health problem into its component parts. Rates, Ratios, and Alternative Denominators. Cluster bar charts with more than two bars per cluster (e.g., Figure 6.16, panel B) are not recommended. Use six or fewer tick mark labels on the axes. In a studyon dengue infection in India for the Government of India Ganeshkumar et al., (2018), presented systematically case fatality and its prevalence from Meta-analysis of epidiemological data. , https://www.coursehero.com/file/57963684/HLT-362V-69docx/, Health (6 days ago) Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Rates correct counts for differences among population sizes or study periods. Health. Each spot in the plotting area represents the joint magnitude of the two variables. The map is divided into population enumeration areas for which rates or ratios can be computed. For example. 1 posts Re: Topic 5 DQ 1 Epidemiology refers to the study of the distribution and determinants of diseases in a population. Mean, median, range, and interquartile range of body mass index measurements of 1,800 residents, by education level: Ajloun and Jerash Governorates, Jordan, 2012. Cookies used to make website functionality more relevant to you. A first and simple step in determining how much is to count the cases in the population of interest. Epidemiological data helps to plan and strategies to prevent and manage epidemic diseases or illness. Significant spacetime clustering (assessed by the Knox test) of dengue cases in the city of Cairns, Australia, during JanuaryAugust 2003. As an alternative to using tables, charts (Box 6.12) (e.g., dot charts) (Figure 6.16, panel A) or horizontal cluster bar charts (Figure 6.16, panel B) improve perception of the patterns in the data, compared with a table. Epidemiological methods can be used to identify which risks pose the most serious health threats. The averages and dispersions can be displayed in a table or visualized in a box-and-whisker plot that indicates the median, mean, interquartile range, and outliers (Figure 6.1) (5). These are generally accompanied by an API that allows users to programmatically acquire desired data. Adhere to mathematical principles in plotting data and scaling axes. Dot plots, box plots, and bar charts are easier to understand and read if aligned horizontally (with the numeric axis horizontal). Scale the graph to fill the data space and to improve resolution. Plotting only numerators loses the advantage of both the spot map (indicating exact location and detailed background features) and the area map (indicating rates). Epidemiological findings thereby help Government and healthcare organisations to implement methods of prevention, intervention and policymaking. < Previous Chapter 5: Using Technologies for Data Collection and Management, Next Chapter 7: Designing and Conducting Analytic Studies in the Field>. Represent dependent variables on the vertical scale and independent variables on the horizontal scale. Describe how epidemiological data influences changes in health practices. Epidemic curves (Box 6.5) are histograms of frequency distributions of incident cases of disease or other health events displayed by time intervals. Emerging infectious diseases (EID) are caused by viral or bacterial pathogens causing diseases that may be communicable or non-communicable. The continuing common source epidemic curve will increase sharply, similar to a point source. Interveners of epidemiology comprise of members from the pharmaceutical, healthcare industries, political epidemiologists and the policymakers of India. An epidemic curve with a tight clustering of cases in time (1.5 times the range of the incubation period, if the agent is known) and with a sharp upslope and a trailing downslope is consistent with a point source (Figure 6.3) (6). The application period for EIS Class of 2024 will be open March 1-June 5, 2023. Therefore, epidemiological data for Malaria will be chosen and the results of the analysis will help assess the prevalence of the disease. Describe how epidemiological data influences changes in health practices. (2018). Common EIDs are HIV, Malaria, Zika virus and many others to name. This puts each stratum on a flat baseline, enabling undistorted comparisons. Use other intervals (e.g., weeks or days) accordingly. A trend line of best fit underlying the data markers. Dot and box-and-whisker charts are plotted against a numeric scale and thus do not need a zero level. On the opposite end of the scale, injuries and acute poisonings have instantaneous and obvious onsets. Cases of Salmonella enterica serovar Heidelberg infection, by illness onset date: Colorado, July 10 August 17, 1976. Primary care epidemiology is needed to describe: the incidence, prevalence, severity and natural history (duration, remission and recurrence) of symptoms and signs, and of defined illnesses occurring in the community; how these problems vary among different groups within the community (e.g. 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. High-end software and tools such as R-package, SAS, Minitab, Python and other similar languages and statistical programs are used by pharmaceuticals and healthcare agencies. In Figure 6.15, a distinctive pattern of rapidly increasing cholera death rates is apparent as the altitude approaches the level of the River Thames. Epidemic curves from environmentally spread diseases reflect complex interactions between the agent and the environment and the factors that lead to exposure of humans to the environmental source. Rates are normally displayed on area maps (e.g., patch or choropleth). Information about place of affected persons might include residence, workplace, school, recreation site, other relevant locales, or movement between fixed geographic points. It often elicits a response from public health practitioners on how to respond to epidemiological data on health and illness. The following image presents an exclusive example of the use of an epidemic curve over a specific time. Secondary applications include helping in ground-level achievement (rural and district level) of policy implications by the Government and management and control of diseases. Avoid pie charts, cluster bar charts, stacked bar charts, and other types not presented in this chapter. Epidemiological data influences health care, How does epidemiology influence healthcare, Epidemiological data and health practice, Epidemiology and population health challenges. Although graphs can be attained from different types of tools and software, the presentation of graphs and usage of data types remain the same. Age-specific mortality rates per 100,000 population/year: United States, 1910, 1950, and 1998. Provide an example and explain what data would be necessary to make a change in practice. To indicate divergence from an average range, use white for the center range and deepening intensities of two different hues for divergent strata on opposite extremes. For example, a maternal mortality ratio and infant mortality rate use births in a calendar year as a denominator for deaths in the same calendar year, yet the deaths might be related to births in the previous calendar year. For example, overweight prevalence in the Ajloun data can be compared by using different education levels. How much? is expressed as counts or rates. The x-axis represents a period of interest. Epidemiologists , https://www.cdc.gov/csels/dsepd/ss1978/lesson1/section1.html, Health (9 days ago) Epidemiological data influence health practices change, such as creating awareness on health crises that are likely to occur in a particular population. Cookies used to enable you to share pages and content that you find interesting on CDC.gov through third party social networking and other websites. This helps in stricter policy-making even for the pharmaceuticals towards usage and manufacturing of new drugs and associated clinical tests. Emerging Infectious Diseases. 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 (CDC, 2012). In addition, it also helps the pharmaceutical industries to assess clinically if the intervention methods or drugs or treatment methods are efficient enough for eradication and prevention of the disease. In addition, there are other forms of presentation of graphical presentations from the epidemiological data analysis. These cookies perform functions like remembering presentation options or choices and, in some cases, delivery of web content that based on self-identified area of interests. Text that highlights the main patterns of the data (this text might appear within the table or graphic or in the body of the report). After the data are organized and displayed, descriptive epidemiology then involves interpreting these patterns, often through comparison with expected (e.g., historical counts, increased surveillance, or output from prevention and control programs) patterns or norms. http://www.cbhidghs.nic.in/index1.php?lang=1&level=2&sublinkid=88&lid=1138. Aspect ratios (data space width to height) of approximately 2:1 work well. Similarly, in the case of poor infrastructure, the political strategists help the Government in the identification of the factor. Ganeshkumar, P., Murhekar, M. V., Poornima, V., Saravanakumar, V., Sukumaran, K., Anandaselvasankar, A., John, D., Mehendale, S.M., 2018. The underlying epidemiologic process might produce disease distributions within and among social groupings that range from strong aggregation to randomness or uniformity. Epidemiology is a discipline that has a crucial role in describing health status, identifying risk factors, and , https://classywriters.net/describe-how-epidemiological-data-influences-changes-in-health-practices/, Health (Just Now) Describe how epidemiological data influences changes in health practices. The areas are then ranked into strata by the rates, and the strata are shaded (Box 6.10) according to the magnitude of the rate. Rev Bras Epidemiol 16, 317. This leads to the implementation of the policy that focuses on better living and lifestyle and improvement of proper sanitation. Source: Adapted from: Ajloun Non-Communicable Disease Project, Jordan, unpublished data, 2017. Working on your paper. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Thank you for taking the time to confirm your preferences. Provide marginal averages, rates, totals, or other summary statistics for rows and columns whenever possible. https://doi.org/10.1371/journal.pntd.0006618. Discuss , https://www.sweetstudy.com/questions/1-describe-how-epidemiological-data-influences-changes-in-health-practices-provide-an-example-and-explain-what-data-would-be-necessary-to-make-a-change-in-practice, Health (7 days ago) Describe how epidemiological data influences changes in health practices. In a health report for the National Rural Health Mission (NRHM) by the Ministry of Health and Family Welfare in 2017, used rural public economic and financial data to assess the publics capability to comprehend various forms of diseases. Describe how epidemiological data influences changes in health practices. The following sections describe certain kinds of epidemic situations that can be diagnosed by plotting cases on epidemic curves. Seasonal distribution of malaria cases, by month of detection by voluntary collaborators in four villages: El Salvador, 19701977. Instead, put them just outside the data region. On an arithmetic scale, represent equal numerical units with equal distances on an axis. Certain behaviors (e.g., drug addiction or mass sociogenic illness) might propagate from person to person, but the epidemic curve will not necessarily reflect generation times. Smaller or compressed type and papers with small margins or single-spacing are hard to read. The following graphical presentation was used by CDC, (2016) in a study to show the prevalence of malarial demographics in India. Use the table layout to guide the eye. Epidemiological data helps search for the cause and determinants that influence the occurrence of a particular disease or any other health crisis. Saving Lives, Protecting People. In addition, maps display a wealth of underlying detail to compare against disease distributions. Incidence cases, mortality, local and national data, financial and economic data, drug-based data, and interventional data, Trend-based, geospatial, forecasting, econometrics, multivariate analysis, correlations and regressions and others. The choice between tables and charts depends on the purpose, the audience, and the complexity of the data. Statistical analyses of epidemiological data are presented empirically, graphically, or in pictorial format. We have been assisting in different areas of research for over a decade. The outcomes will help to understand how Government applications in the control and management of Malaria and policy implications. Decrease the time interval size as case numbers increase. You might also use spot maps to represent affected villages, towns, or other smaller population units. The points within or closest to the centre line, show efficiency to the intervention method. A well-structured analytical table that is organized to focus on comparisons will help you understand the data and explain the data to others. These cookies may also be used for advertising purposes by these third parties. Formation and amendment of healthcare policies need data, statistics, and its outcomes. The epidemic curve graph is clear on the presentation of epidemiological data of Malaria and its epidemic data as of how the case incidences prevail over time and period. To assess adverse effects from a vaccine or pharmaceutical, consider using total doses distributed as the denominator. BMI, Body mass index; F, female; M, male; SD, standard deviation. Often, a periodicity equivalent to the generation period for the agent might be obvious during the initial stages of the outbreak. Cases are customarily organized in a table called a line-listing (Table 6.1) (2). Retrieved August 30, 2018, from, National Institute of Epidemiology, 2018. Random or uniform distributions indicate that the exposure lies outside the group. The data mainly comprises of economic and financial data and disease-based demography data. Describe how epidemiological data influences changes in health practices. al., 2018). 3 years ago. Never mix incident with prevalent cases in epidemiologic analyses. For most conditions, a time characteristic of interest is the secular trendthe rate of disease over multiple years or decades. All information these cookies collect is aggregated and therefore anonymous. It allows the healthcare to effectively provide health care services to the public mainly the poor and the rural. This reveals that factor and that an environmental exposure also related to low altitude (e.g., poor drainage of sewage) might have contributed to cholera incidence. This will also implicate the efficacy of the healthcare and the pharmaceuticals in the provision of quality treatment methods and drugs for control of Malaria prevalence and their role in helping the Government achieve its healthcare objectives. In the case of pharmaceutical, they directly assess statistically the efficiency of drug-based intervention methods for the control of infectious diseases. Graphs are most frequently used for displaying time associations and patterns in epidemiologic data. Frequency in the graphical outcomes indicates the tally of disease cases and incidences. More than that becomes confusing clutter. Contact between severe acute respiratory syndrome (SARS) cases among a group of relatives and health care workers: Beijing, China, 2003. Estimation and Inference for Measures of Association, in: Statistics for Epidemiology. Let the difference in shading of map areas define and replace detailed internal boundary lines. Epidemiology plays a crucial role in identifying the risk factors, describing the health status of a population, and establishing the relationship , https://essayzoo.org/essay/apa/health-and-medicine/discussion-epidemiological-data.php, Health (Just Now) 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. To reveal distinctive internal patterns (e.g., by exposure, method of case detection, place, or personal characteristics) in time distributions, epidemic curves should be stratified (Figure 6.9). The epidemic curve accompanying the severe acute respiratory syndrome (SARS) contact diagram (Figure 6.2, panel B) illustrates these features, including waves with an approximate 1-week periodicity. The following image shows an example of the use of outcome from disease interventions, whereby the graph presents the comparison between different intervention methods. Dengue infection in India: A systematic review and meta-analysis. The graphical presentation clearly shows the prevalence of Malaria and its related demographics over a geographical location using a map and scatter plot. Through this process of organization, inspection, and interpretation of data, descriptive epidemiology serves multiple purposes (Box 6.1). Directorate General Of Health Services, 2018. Defined as current use of asthma medicine or one or more of the following symptoms during the previous 12 months: wheezing or whistling in the chest, awakening with a feeling of chest tightness, or attack of asthma. In a report for the National Health Profile (NHP) of India in 2018 by the Directorate General Of Health Services, (2018), India used state wise demographics for different factors causing the prevalence of Malaria. The epidemic curve for a zoonotic disease among humans typically mirrors the variations in prevalence among the reservoir animal population. We are seeking an enthusiastic and dedicated colleague with expertise in epidemiology, longitudinal methods, and youth mental health who can make a distinctive contribution to education and drive forward collaborative high-quality research. Majumder, Avishek, & Abhinash Jena (2018, Oct 30).
