case series study definition

Jul 17,  · Consequently, a case series cannot be comparative. The definition of a case series by Dekkers et al. is summarized in Table 4. It is noteworthy that the conceptualization also ensures a clear distinction of case series from other study designs that apply outcome-based pjointones.gq by: A systematic review of prazosin ( mg) for PTSD included 21 studies (4 RCTs, 4 open-label case series, 4 retrospective case series, and 9 case reports) with patients, 85% of whom were combat veterans. Case series are a commonly reported study design, but the label "case series" is used inconsistently and sometimes incorrectly. Mislabeling impairs the appropriate indexing and sorting of evidence.


Case series | definition of case series by Medical dictionary


In the social sciences and life sciencesa case study is a research method involving an up-close, in-depth, and detailed examination of a subject of study the caseas well as its related contextual conditions. Case studies can be produced by following a formal research method. These case studies are likely to appear in formal research venues, as journals and professional conferences, rather than popular works.

The resulting body of 'case study research' has long had a prominent place in many disciplines and professions, ranging from psychology, anthropology, sociology, and political science to education, clinical science, social work, and administrative science. In doing case study research, the "case" being studied may be an individual, organization, event, or action, existing in a specific time and place.

For instance, clinical science has produced both well-known case studies of individuals and also case studies of clinical practices. Another suggestion is that case study should be defined as a research strategycase series study definition, an empirical inquiry that investigates a phenomenon within its real-life context.

Case study research can mean single and multiple case studies, can include quantitative evidence, relies on multiple sources of evidence, and benefits from the prior development of theoretical propositions.

Case series study definition studies should not be confused with qualitative research and they can be based on any mix of quantitative and qualitative evidence. Single-subject research provides the statistical framework for making inferences from quantitative case-study data. In business research, four common case study approaches are distinguished, case series study definition. Eisenhardt 's methodological work. Yin 's guidelines and making positivist assumptions.

There are substantial methodological differences between these approaches. An average, or typical case, is often not the richest in information. In clarifying lines of history and causation it is more useful to select subjects that offer an interesting, unusual or particularly revealing set of circumstances.

A case selection that is based on representativeness will seldom be able to produce these kinds of insights. When selecting a case for a case study, researchers will therefore use information-oriented sampling, as opposed to random sampling. Alternatively it may be chosen because of researchers' in-depth local knowledge; where researchers have this local knowledge they are in a position to "soak and poke" as Richard Fenno put it, [15] and thereby to offer reasoned lines of explanation based on this rich knowledge of setting and circumstances.

Whatever the frame of reference for the choice of the subject of the case study key, outlier, local knowledgethere is a distinction to be made between the subject and the object of the case study. The subject is the "practical, historical unity" through which the theoretical focus of the study is being viewed. Thus, for example, if a researcher were interested in US resistance to communist expansion as a theoretical focus, then the Korean War might be taken to be the subjectthe lens, the case study through which the theoretical focus, the objectcould be viewed and explicated.

Beyond decisions about case selection and the subject and object of the study, decisions need to be made about purpose, approach and process in the case study. Gary Thomas thus proposes a typology for the case study wherein purposes are first identified evaluative or exploratorycase series study definition, then approaches are delineated theory-testing, case series study definition or illustrativethen processes are decided upon, with a principal choice being between whether the study is to be case series study definition or multiple, and choices also about whether the study is to be retrospective, snapshot or diachronic, and whether it is nested, parallel or sequential.

Some cases study marketing analysis to ensure a full understanding of the effects on an organization. In a case where the market of any organization is in jepoardy, case series study definition, the agency will seek answers and solutions.

In order to fulfill this need, the organization must gather pertient information. Case studies can be used to establish where the problem originates by utilizing several research methods.

The primary methods used include: interviews, surveys, focus groups, observations and in some cases, field trials. In public-relations research, three types of case studies are used: [21]. Under the more generalized category of case study exist several subdivisions, each of which is custom selected for use depending upon the goals of the investigator.

These types of case study include the following:. At Harvard Law School InChristopher Langdell departed from the traditional lecture-and-notes approach to teaching contract law and began using cases pled before courts as the basis for class case series study definition. Research in business disciplines is usually based on a positivist epistemology[24] namely, that reality is something that is objective and can be discovered and understood by a scientific examination of empirical evidence.

But organizational behavior cannot always be easily reduced to simple tests that prove something to be true or false. Reality may be an objective thing, case series study definition, but it is understood and interpreted by people who, in turn, act upon it, and so critical realismwhich addresses the connection between the natural and social worlds, is a useful basis for analyzing the environment of and events within an organization.

Case studies in management are generally used to interpret strategies or relationships, to develop sets of "best practices", or to analyze the external influences or the internal interactions of a firm. Frederic Le Play first introduced the case-study method into social science in as a handmaiden to statistics in his studies of family budgets.

In all these disciplines, case studies were an occasion for postulating new theories, as in the grounded-theory work of sociologists Barney Glaser and Anselm Strauss One of the areas in which case studies have been gaining popularity is education and in particular educational evaluation. Comparative case studies, in social science, policy, and education research; discusses one approach, which encourages researchers to compare horizontally, vertically, and temporally. Using case studies in research differs from their use in teaching, where they are commonly called case methods and casebook methods.

Teaching case studies have been a highly popular pedagogical format in many fields ranging from business education to science education. Harvard Business School has been among the most prominent developers and users of teaching case studies. Additional relevant documentation, such as financial statements, time-lines, and short biographies, often referred to in the case study as exhibits, and multimedia supplements such as video-recordings of interviews with the case subject often accompany the case studies.

Similarly, teaching case studies have become increasingly popular in science education, case series study definition. The National Center for Case Studies in Teaching Science has made a growing body of case studies available for classroom use, for university as well as secondary school coursework.
