Case Control Study – a Short Essay
Case control study – A short essay
Epidemiologic research encompasses several types of study designs, including experimental studies and observational studies. Each type of epidemiologic study design simply represents a different way of gathering and interpreting information. The selection of one design over another depends on the particular research question, concerns about validity and efficiency, and practical and ethical considerations. Most researchers prefer case control study design over other study designs. Case-control is a type of epidemiological, clinical study design. It is typically used for retrospective studies. In a case-control study, people with a disease (often, a specific diagnosis, perhaps lung cancer) are matched with people who do not have the disease (the 'controls'). Further data are then collected on those individuals and the groups are compared to find out if other characteristics (perhaps a history of smoking) are also different between the two groups. According to Mosby's Medical Dictionary, (8th edition 2009) a case-control study is a nonexperimental research design using an epidemiologic approach in which previous cases of the condition are used in lieu of new information gathered from a randomized population. A group of patients with a particular disease or disorder, such as myocardial infarction, is compared with a control group of persons who have not had that medical problem. The two groups, matched for age, sex, and other personal data, are examined to determine which possible factor (e.g., cigarette smoking, coffee drinking) may account for the increased disease incidence in the case group. Case control studies are more preferred by the researchers or investigators due to a lot of reasons. Let’s talk about a few of the advantages of the case control study  Rapid and easy to carry out  Economic  Comparatively few subjects are required  No risk to subjects  Risk factors can be identified  Minimal or no ethical issues

    Firstly, Alejandro’s team members did not view him as an authentic leader. They had no respect for or confidence in him probably because they sensed his self doubt so they disregarded his plan and did not pay attention. Secondly, Dan answered his phone and left for his weekly tennis game which everyone seemed to know about except Alejandro. As soon as the other team members saw that Dan wasn’t interested enough to participate in the meeting, they also lost all interest and followed through with the disrespect because they viewed Alejandro’s plan as just another idea so they began to come up with a plan of their own. Alejandro’s first mistake was that he had no confidence in himself. For example, when Dan initially assigns him with the task, he began to doubt himself and questions the reasons why Dan chose him rather than the “old hands” with more experience. This shows that he wasn’t aware of his strengths and weaknesses so he was unable to present his plan effectively and confidently. Additionally, Alejandro failed to get the other managers involved in his plan to help motivate the other team members.…

    The definition of epidemiology is very important if one is to use the definition to describe its purpose. “A common definition of epidemiology is the study of the distribution and determinants of disease frequency in human populations.” (Savitz, et al, 1999). Scott and Marshall (2008) do a better job when they describe epidemiology as “the analysis of the incidence and spread of disease within populations, with the aim of establishing causality.” The purpose of epidemiology is to find the causes of diseases that affect a population. The discipline of epidemiology influences the practices of both clinical medicine and public health. Epidemiology can be used as a major determinant of evidence based practice because the outcome of surveillance is often used to guide changes in how these disciplines practice. Epidemiological studies can also influence the types of services offered by community agencies…

    The control group should be representative of the population from which the case group was drawn. Sometimes controls are individually matched to cases: known disease-risk factors such as age and sex are then similar in each case. This allows scientists to investigate the potential role of unknown risk factors. It should be noted that factors used to match the cases cannot be investigated within the study, so it is important not to match on variables which could potentially be risk factors.…
