EPIDEMIOLOGY PAPER NRS 428
The rates and the occurrences of diseases among populations serve as an important aspect of exploration in the field of nursing. Knowledge about the patterns of infections not only improve intervention but also provides a platform to optimize quality of care to patients. Often, the health of populations in a given locale depends on several factors. It is imperative to describe the health status of the population as well as identify risk factors in addition to analyze the relationships between health and hazardous agents potential in causing diseases (Evans‐Agnew et al., 2017). The field of epidemiology fills this void by monitoring, investigating as well as evaluating the patterns of occurrences of different diseases within the public health systems. Particularly, the concepts of descriptive epidemiology provide an in-depth analysis of disease patterns and therefore forms the topic for this study.
Descriptive Epidemiology and its Relationship and Role in Nursing Science Today
Descriptive epidemiology is concerned with the description of the distributions and the determinants of diseases. The field delves into an elaboration about the patterns of organization and the analysis of data to describe variations as well as the frequency of diseases among populations. Essentially, according to Bach et al. (2017), descriptive epidemiology is based on a measure of incidence and prevalence rates of diseases so as to provide fundamental information key in health policy decisions. This type of epidemiology also serves special tasks especially in the field of nursing science. Specifically, descriptive epidemiology guides in the identification of emerging health problems. It also serves in the reporting as well as monitoring the patterns of behavior linked to these conditions among selected populations. Additionally, investigations and evaluations of the disease occurrences help policymakers in the field of public health to lay down priorities of care for the population at risk of a condition. Through descriptive epidemiology, a hypothesis can be derived to generate possible explanations related to the potential determinants of a given disease that affects a population under study. The rates and occurrences of emerging diseases are one of the crucial aspects in the field of public health. Specifically, descriptive epidemiology can provide an alert about potential bioterrorism threats that might pose a health risk to a selected population. Nonetheless, descriptive epidemiology provides a benchmark to measure and analyze the efficiency of a given health intervention program.
As a descriptive study, this type of epidemiology avails data that can be used for the prevention of a given illness through the design of a suitable intervention strategy. Besides, the field lays a platform for additional research on the prevention and management of an emergent disease. This is evident when the field is used to identify problems through analytic methods and therefore can be used to suggest specific areas that might prove fruitful for future investigations (Evans‐Agnew et al., 2017). In order to provide concrete evidence about the morbidity patterns of different illnesses, descriptive epidemiology mainly classifies disease occurrences according to person, time and place. The data compiled is of immense value to nursing science today as it provides a detailed account about the health of a given population. With this information, descriptive analysis can be generated from tables, maps or graphical representations.
Occurrences of disease are influenced by the type of person. Descriptive epidemiology explores the latter in terms of age, sex, race, and socioeconomic status. Besides, the analysis is also made based on biological factors as well as the state of physical activities in addition to the living conditions of the populations. Age is an important aspect of a person as it influences the patterns of health. Infants and the elderly are more susceptible to diseases as opposed to other age-sets.
The aspect characterizes cyclic fluctuations, secular trends and the points of an epidemic of specific illnesses under study. The discipline of nursing sciences uses descriptive epidemiology to analyze the occurrence of diseases based on time. From the analysis, it is apparent that some disease conditions occur regularly and therefore can be predictable within a given timeframe. However, some infections are temporal and they may occur unpredictably among a selected population under study (Bach et al., 2017). Diseases that occur in seasons allow nurses to predict the patterns of their manifestations and this helps to formulate interventions in a target population.
The aspect relates to the location of a study population. It may encompass spatial clustering, urban, rural, regional or international setting of a person. Findings by Frérot et al., (2018) affirm that patterns of disease occurrences are influenced by habitation or area of residence of a person. Descriptive epidemiology characterizes a disease based on a place by focusing on the relevant geographical location in which the condition is prevalent. The premise guides the selection of relevant intervention strategies to control the spread of the disease to other regions.
Contemporary Example of how Descriptive Epidemiology is applied in Public Health Nursing
Descriptive epidemiology examines the patterns and the frequency of various disease conditions. The investigations about the causes are vital in public health nursing as it provides relevant data that guide in the selection of an intervention strategy. As a discipline in public health nursing, descriptive epidemiology delivers information that can be used to promote community health and device active initiatives to support the lives of a populace at risk of a given disease (Tripathy, 2016). In the treatment process, public health nurses need to identify creative approaches that can optimize patient care by focusing on the evidence-based scientific modalities to guide on a decision of health service delivery. Descriptive epidemiology fills the void by evaluating the trends of health service delivery and compares the same with the patterns of disease occurrences.
Descriptive epidemiology is consistent with the Three Cs Lydia Hall’s theory of nursing. The theory defines nurses as key participants in patient care. As per the three Cs of the theory, nurses are concerned with the aspect of care while the core and cure concepts are shared with other cadres of health (Johnson et al., 2017). In other words, the concept of descriptive epidemiology provides insights on the treatment and prevention of disease which gives the process of care a team approach as it involves contributions from all stakeholders. However, information on the current methods of care is derived from research analysis organized through consistent studies in epidemiology. A typical example of descriptive epidemiology in the field of public health nursing can be interpreted through an analysis of tuberculosis (TB) condition.
TB is a serious infectious mainly localized in the lungs. The condition is a respiratory disease predominantly transmitted through aerosols when an infected person coughs, spits or sneezes. By the end of the twentieth century, TB was among the killer diseases in the United States of America. However, throughout time, comprehensive tests and tracking of the condition have led to effective management of the ailment which emerges as one of the diseases of public health concern in the world today (Guta et al., 2014). Through descriptive epidemiology, the symptoms of the condition have been identified, monitored and reported. Besides, the causative agents and the means of transmission have been analyzed to provide a framework of control. Nonetheless, the at-risk population especially those with immune-deficiency disorders have been identified among different populations of the world. With this information, targeted intervention has been undertaken to curb the menace among the at-risk population (Km et al., 2018). Moreover, descriptive epidemiology has guided on the selection of prevention measures to control the spread of the infection. Through descriptive epidemiology, “lessons learned” about TB have been identified among the at-risk populations and these have provided new information on how to control the spread of the infection.
Epidemiology Components used to analyze at-risk Populations
The population at risk of a health condition provides an integral part of epidemiological study. Several components of epidemiology need to be considered during the analysis of the at-risk population. One of the crucial components points to the study participants as determined by the sample size (Tripathy, 2016). The number of the subjects for a given epidemiology research guides in the interpretation of the demographic data. It also helps in the monitoring of characteristics of subjects.
Exposure assessment as the other component focuses on the environmental aspects that predispose a population to a given health risk. This entails the analysis of the quality of exposures to validate the occurrence of a condition. Outcome assessment, on the other hand, remains a vital component to analyze the results of the exposure to a specific agent of a disease (Frérot et al., 2018). The findings guides in the selection of intervention strategies. Assessment of the strength of evidence is another component that guides in the evaluation of exposure to causative agents.
