In evidence base practice cross-sectional, cohort, and RCTs fall under quantitative research. Although the type of design that is used to conduct the research may be different all three styles have numerical data that can be analyzed in order to identify an association between variables. In public health, this type of research helps develop a hypothesis where a research can make observations, run the experiment, and develop programs to address the issue. Nevertheless, the differences between the styles is that cross sectional studies are set in one point in time. For instance, the Centers for Disease and Control and Prevention, NHANES survey, gathers data from a specific point in time to assess the health of the nation. Cohort studies are
An example of evidence based practice would be to find relevant studies for a specific topic area being researched. For example, to find the research paper titled ‘The efficiency of cotton cover gowns in reducing infection in nursing Neutropenic patients,’ the journal in which the article was published in this case, The International Journal of Nursing, would need to be found. Medline, an online database would be one method of finding this. A list of relevant search terms would then need to be researched by using the PICO Framework, this limits the search to only relevant items and ensures that a well built clinical question will then be formulated (Drummond,1998).
What is meant by evidence-based practice and how is this different from an historical standpoint.
Described below is a critical appraisal of a qualitative article by Lisa Booth using the frame-work suggested by Ryan, Coughlan and Cronin 2007 to establish its believability, robustness, credibility and integrity (Ryan, Coughlan & Cronin, 2007).
In this case I will discuss evidence based nursing problem which has a very big impact to the nurses which is evidence- based practices for safe patient handling and movement. Evidence-based practice is critically appraised and scientifically proven evidence for delivering quality health care to a specific population. This is very important because it will help me in reduction of injuries that are associated with patient handling. There are very many approaches that can be used or rather are used in patient handling. These includes manual patient lifting, classes in body mechanics, training in safe lifting techniques, and back belts. Amazingly there has been a strong evidence that this methods still they do not help in reducing nurses or caregiver’s injuries.

As social workers there will be numerous times in which one must do research on a certain topic or case they are working on. When conducting both qualitative and quantitative research, there is a logical sequence of events; both types articulating a clear problem statement must precede all other tasks (Yegidis, Weinbach, & Myers, 2012, p. 55). If one does not have a clear problem statement, then the results may not be exactly what one is looking to achieve. Time is a precious entity, whether you are a client, researcher, social worker, whatever the case; one must a clear research problem so that time is not wasted on other aspects that have nothing to do with the end result. Conducting research can be an intense process, in using the proper
The development of knowledge requires a number of processes in order to establish credible data to ensure the validity and appropriateness of how it can be used in the future. For the healthcare industry, this has provided the ability to create and form new types of interventions in order to give adequate care across a of number of fields within the system. Research then, has been an essential part in providing definitive data, either by disproving previous beliefs or confirming newly found data and methods. Moreover, research in itself contains its own process with a methodological approach. Of the notable methods, quantitative research is often used for its systemic approach (Polit & Beck, 2006). Thus, the use of the scientific method is used, which also utilizes the use of numerical data (Polit & Beck). Here, researches make use of creating surveys, scales, or placing a numerical value on it subjects (Polit & Beck). In the end the resulting data is neutral and statistical. However, like all things its approach is not perfect, yet, it has the ability to yield valuable data.

One feature of evidence based practice is a problem-solving approach that draws on nurses’ experience to identify a problem or potential diagnosis. After a problem is identified, evidence based practice can be used to come up with interventions and possible risks involved with each intervention. Next, nurses will use the knowledge and theory to do clinical research and decide on the appropriate intervention. Lastly, evidence base practice allows the patients to have a voice in their own care. Each patient brings their own preferences and ideas on how their care should be handled and the expectations that they have (Fain, 2017, pg.
Epidemiology is the study of the distribution and determinants of health related states or events in well-defined populations. The goal of epidemiology is to understand the causes of disease variation and limit disease, injury and death in a community by intervening to prevent or limit outbreaks or epidemics of disease and injury. Epidemiology provides the most compelling evidence for measuring environmental risk to humans. Epidemiologists are public health professionals who investigate occurrence of disease-or other health related conditions or events in specific populations. Epidemiology allows public health workers to organize, analyze & interpret statistical facts about health problems. The basic design strategies applied in epidemiological research can be generally categorized according to whether such investigations focus on reporting the distributions of disease or elucidating its determinants. All study designs involve descriptive and analytical type of comparison of exposure and disease status. Descriptive epidemiology focuses on the general characteristics of the distribution of a disease. Analytical epidemiology focuses on the determinants of a disease by testing the hypothesis formulated from descriptive studies to check whether a particular exposure causes or prevents disease.
In the previous chapters I discussed the problem of the lack of healthy eating promotion programs in schools are leaving parents and students uneducated about how to purchase healthy items which is leading to childhood obesity. I also discussed how the problem is being addressed, as well as the theory of social constructionism. In this chapter, I will discuss the specific methodology I plan to use and the three different types of data collection I plan to employ to carry out my study. This study will use a qualitative approach to study and address the issue of the lack of healthy eating promotion in schools. The three types of data collection I plan to use are: direct observation, focus groups and a questionnaire. These methods will be clarified later in this chapter.

Research in multidisciplinary public health can be challenging. There can be serious tension generated among the participants in the research process concerning which approaches are best suitable for the research. Also, the choice of methods to be considered from a compendium of methods that best suits a study could be a herculean task to overcome owing to the differences in the interests and views of the various disciplines involved in public health research (Saks, 2013). This could result in a pyramid of research approaches where an approach is seen by professionals as more scientific and more relevant to public health than others. Research approaches have been observed in the past to have a vertical relationship with each other. In today’s multidisciplinary public health, there is a need to consider them as a spectrum having a horizontal rather than a vertical relationship. This could present a challenge to a new researcher in the field who does not know all the approaches are available and the best applicable to a study. Also, the experienced researcher who already has a particular approach of preference and considers others as inferior may not be applying the best approach available to a study owing to this bias. There is a need for researchers in public heath to be dexterous in research methodology by moving beyond the limits of one’s discipline and gaining skills in a spectrum of approaches available and probably use a blend of methods so as to effectively conduct research (Daly, 1997). As such, I will be discussing Ethnography and Participatory Action research approaches relevant to multidisciplinary public health. I will examine their theoretical and epistemological basis and reflect on their strengths and weaknesses.
Quantitative is numerical or statistical data which often comes from surveys, surveillance or administration records. Quantitative evidence provides a good overall picture of a population or geographical region. It can often be used to measure trends over time. It describes who, what, where and when. Quantitative has four main designs, Descriptive, Correlational, Experimental and Quasi-experimental. Descriptive is the characteristics of individuals, situations or groups and the frequency which with certain phenomena occur using statistics to summarise and describe data. Correlational, interrelationship amongst variables of interest without any active intervention by the researcher. Experimental is systematic and objective, investigator controls the independent variable and randomly assigns subjects to different conditions (Ingham-Broomfield, n.d.).
It would also work on the Cross-sectional method of study and the longitudinal method of study. The research scholar would also work to draw a comparison between both the methods of the study.
