In todays information age, the challenge is not the lack of data but rather how to identify the most relevant data for meaningful results and how to combine data from various sources that might not be standardized or interoperable to enable analysis. Recognizing disease patterns by personal attributes (e.g., age, sex, education, income, or immunization status) constitutes the fifth element in descriptive epidemiology. 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).

Although public health departments have access to notifiable disease case data (primarily for communicable diseases) through mandatory reporting by providers and laboratories, data on chronic diseases and injuries might be available only through secondary sources, such as hospital discharge summaries. Secular trends of invasive cervical cancer (Figure 6.11) reveal steady decreases over 37 years (11). The example spot map of a dengue outbreak uses larger dots to represent cases clustered in time and space and numbers these clusters to reference to a table (not shown). You will be subject to the destination website's privacy policy when you follow the link. The best charts for quick and accurate understanding are dot plots, box-and-whisker plots, and simple bar charts. Discussing up front the purpose of the investigation and the data collection processes will prove invaluable in the long run when collaborators are needed during case finding, data collection, implementation of control measures, and communication with affected populations and the public. You can review and change the way we collect information below. For example, the map of spotted fever rickettsioses in the United States effectively displays multiple levels of risk for human infection (Figure 6.14) (15). To indicate no data, use a different hue or fill pattern. Rates are normally displayed on area maps (e.g., patch or choropleth). Provide an example and explain what data would be necessary to make a change in practice. 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. The epidemiologist must keep in mind that the primary purpose of a field investigation into an urgent public health problem is to control the problem and prevent further illness. In field investigations, tradeoffs exist between these attributes; for example, a more timely collection of data might lead to lower quality data, fewer resources might mean less complete data, and retrospective analysis of preexisting data might be more cost-effective, although prospective data collection from case-patients might enable more targeted questions about specific exposures. Students of journalism are taught that a good news story, whether it be about a bank robbery, dramatic rescue, or presidential candidates speech, must include the 5 Ws: what, who, where, when and why (sometimes cited as why/how). View the Furthermore, EHRs contain potentially useful data on healthcare use, treatment, and outcomes of a diseaseelements not typically assessed by more traditional public health data sources. The Health Insurance Portability and Accountability Act (HIPAA) of 1996 (31) has specific language allowing for the use of personal health information by government agencies to perform public health activities. 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. Possible confounders and effect modifiers. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. During the 2016 epidemic of Zika virus infection, understanding the ecologic niche for the Aedes mosquito vector was important when investigating an increase in febrile rash illnesses (Box 4.2) (12). As an alternative to plotting onset by calendar time, plotting the time between suspected exposures and onset can help you understand the epidemiologic situation. They are often different and have distinct epidemiologic implications. WebDescribe how epidemiological data influences changes in health practices. Answered: Describe how epidemiological data | bartleby If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. For example, for a long survey or one with complex skip patterns, an interviewer-administered survey might be better than a self-administered one. These cookies may also be used for advertising purposes by these third parties. Take-Home Point: This outbreak involved many jurisdictions and evolved over a several months. Solved Describe how epidemiological data influences changes Use spot maps to reveal spatial associations between cases and between cases and geographic features. To search for these determinants, epidemiologists use analytic epidemiology or epidemiologic studies to provide the Why and How of such events. Epidemiologic data are paramount to targeting and implementing evidence-based control measures to protect the publics health and safety. Moreover, most, if not all, field investigations will be done by a larger team. They can have various response categories (e.g., nominal, numeric, Likert scales). Pay special attention to ensuring that survey instruments can be used across multiple sites in the event that the outbreak involves multiple jurisdictions. Keep keys, legends, markers, and other annotations out of the data space. Strictly speaking, in computing rates, the disease or health event you have counted should have been derived from the specific population used as the denominator. Indicate the data range in the legend; do not leave it open-ended. Ideally, the findings provide sufficient evidence to direct prompt and effective public health control and prevention measures. 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. < Previous Chapter 3: Conducting a Field Investigation, Next Chapter 5: Using Technologies for Data Collection and Management >. Of note, administration of antimicrobials, immunoglobulins, antitoxins, or other quickly acting drugs can lead to a shorter than expected outbreak with a curtailed downslope. WebThis problem has been solved! Many investigation activities must be conducted in parallel and are interdependent and iterative, with results informing edits or amendments. Solved Describe how epidemiological data influences changes The story of removing the pump handle is the quintessential public health intervention based on scientific data. Let the difference in shading of map areas define and replace detailed internal boundary lines. The media can play important and sometimes conflicting roles during an outbreak. 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. Cookies used to make website functionality more relevant to you. Examples of clinical data sources include medical record abstraction, hospital discharge data (e.g., for cases of hemolytic uremic syndrome) (15), syndromic surveillance systems (16) (e.g., for bloody diarrhea during an Shiga toxinproducing Escherichia coli outbreak) (17), poison control center calls (e.g., exposure to white powder during anthrax-related events) (18), and school and work absenteeism records (e.g., New York City school absenteeism in students traveling to Mexico at the beginning of the influenza A[H1N1] pandemic) (19). Understanding how participants are interpreting and answering questions can enable corrections to the wording before it is too late. If using color, use increasing intensities of the same hue. Describe how epidemiological data influences changes Provide an example and explain what data would be necessary to make a change in practice. Summarize with average rates, average counts, or totals for all the Januarys, Februarys, and so on for each of the 12 months. Reduce embellishments that obstruct a clear vision of disease and potential exposures. The downslope can be precipitous if the common source is removed or gradual if it exhausts itself. Epidemiologic data are paramount to targeting and implementing evidence-based control measures to protect the publics health and safety. Close-ended questions could include cascading questions, which can be an efficient way to get more detailed information as one filters down through a hierarchy of questions (e.g., first you ask the participants state of residence, then a menu of that states counties drops down). Doing so facilitates data exchange with other systems if the outbreak extends to other jurisdictions. Thank you for taking the time to confirm your preferences. Saving Lives, Protecting People, Principles of Epidemiology in Public Health Practice, Third Edition, National Center for State, Tribal, Local, and Territorial Public Health Infrastructure and Workforce, U.S. Department of Health & Human Services, ____ 1. Provide an example and explain what data would be necessary to make a change in practice. The predominant survey conducted in all states is the Behavioral Risk Factor Surveillance System, a random-digit dialed household survey of noninstitutionalized US adults. Factors to consider when deciding on data collection methods include the following: Before developing a survey instrument, review the investigation objectives (i.e., study questions) to identify the specific variables that need to be collected to answer the questions. During the same period, Dr. John Snow, known as the father of modern epidemiology, mapped deaths from cholera in London and determined the Broad Street Pump as the source of contaminated water (4). For prevalence, this fluctuation amplifies the statistical error. Cases not included in clusters are marked with smaller dots. Multiple factors must be considered when identifying relevant data sources for conducting a field investigation. The epidemic curve for a zoonotic disease among humans typically mirrors the variations in prevalence among the reservoir animal population. Describe how epidemiological data influences changes in health To indicate nominative (non-numeric) qualities, use different hues or fill patterns. Response rate. Compute and plot rates for the smallest area possible. Because age is a pervasive determinant of disease and because population groups often differ in their age structures, age adjustment (standardization) is a useful tool for comparing rates between population groups (17). 4th ed. Accordingly, less efficient and inaccurate displays, although common, were avoided or noted as not recommended. Use redundant beginning and end points (see Figures 6.9 through 6.14) to visualize the trend between the last and first months of the cycle. WebExpert Answer. Although the list comprises primarily infectious diseases, in 1995, the first noninfectious conditionelevated blood lead levelswas added (7). Avoid using dividing lines, grids, and other embellishments within the data space. Epidemiology is the study of the distribution and determinants of health The application period for EIS Class of 2024 is now open through June 5, 2023. You should include on the epidemic curve a representation of the suspected environmental factor (e.g., rainfall connected with leptospirosis in Figure 6.7 [9]). When the pattern of the spots forms a compact, linear pattern, suspect a strong association between the two variables. Topic 5 DQ 1 This process continues today; the Council of State and Territorial Epidemiologists determines which diseases and conditions are designated as nationally notifiable to CDC, but each state and territory legally mandates reporting in its jurisdiction. See Answer. Instructions for recruiting and enrolling participants in the survey, including obtaining consent for participation. Cost (e.g., interviewer time). Statistics/Nursing - Describe how epidemiological data This will save time in the long run; many epidemiologists have learned the hard way that a survey question was not clear or was asking about more than one concept, or that the menu of answers was missing a key response category. Source: Adapted from Ajloun Non-Communicable Disease Project, Jordan, unpublished data, 2017. Aspect ratios (data space width to height) of approximately 2:1 work well. Always check whether data sources are providing incident (new events among the population) or prevalent (an existing event at a specific point in time) cases. This 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. NRS-440V Week 5 Assignment Combining Nurse Leader With Advocacy. Random or uniform distributions indicate that the exposure lies outside the group. In surveillance systems, you might have only the report date or another onset surrogate. Since this outbreak was recognized, the epidemic has spread through the mosquito vector as well as through sexual and perinatal transmission to multiple countries and continents around the world. During the 1800s, Dr. William Farr developed a disease classification system that ushered in the era of modern vital statistics (3). They help us to know which pages are the most and least popular and see how visitors move around the site. Create multiple maps to indicate associations of cases to different background features to fully communicate the geographic association between disease and exposure. Is the objective to identify a point source (e.g., a contaminated food item) of an outbreak to recall the product? The difference is that epidemiologists tend to use synonyms for the 5 Ws: diagnosis or health event (what), person (who), place (where), time (when), and causes, risk factors, and modes of transmission (why/how). Provide an example and explain what data would be necessary to make a change in practice. A lock (LockA locked padlock) The last three questions are assessed as patterns of these data in terms of time, place, and person. Use alternating light shading of rows to assist readers in following data across a table. Compare food histories between persons with, ____ 2. Epidemiology and the Delivery of Health Care Services: Methods May 18, 2022 Epidemiology data influence in health practices Describe how epidemiological data influences changes in health practices. Time has special importance in interpreting epidemiologic data in that the initial exposure to a causative agent must precede disease. Outbreaks can arise from common sources that continue over time. Epidemiology After the epidemiologist has confirmed the existence of an urgent public health problem, the next important task in a field investigation is to define the specific objectives and determine what data are necessary and sufficient to justify the control measures. Describe how epidemiological data influences changes in health practices. Describe how epidemiological data influences changes in health practices. This protocol can include the following: Train staff collecting data on the protocol, reviewing instructions carefully and modifying as needed. When interpreting spot maps, keep in mind the population distribution with particular attention to unpopulated (e.g., parks, vacant lots, or abandoned warehouses) or densely populated areas. Epidemic curves for large geographic areas might not reveal the early periodicity or the characteristic increase and decrease of a propagated outbreak. When using transformed data (e.g., logarithmic, normalized, or ranked), represent equal units of the transformed data with equal distances on the axis.
