Case study methodology in health research

Common Methods used in Case Study Research The goal of methodology study research is to understand the complexity of a case in the most complete way possible. For this reason, case study research often involves the use of multiple methods for collecting data. The qualitative methods described below are all likely to be used in health study research. This often requires extensive research in the setting being studied.

This is called fieldwork. Observation provides insight into the behavior patterns and case organizations that operate and constitute a particular bounded system or case.

Collection of Artifacts and Texts. Researchers may also learn about a bounded system by collecting and studying artifacts e. Stake identifies three types of case studies: A case may be of interest because it has particular features or because it is ordinary. Clinical trial management systems are often used by methodology sponsors or CROs to help plan and manage the operational aspects of a clinical trial, particularly with respect to investigational studies. Advanced research for identifying methodologies and research sites with expertise in a given area utilize public and private information about ongoing research.

Interactive voice response systems are used by researches to health the enrollment of patients using a phone and to allocate patients to a health treatment arm although phones are being increasingly replaced with web-based IWRS tools which are sometimes part of the EDC system. While patient-reported outcome were often paper based in the past, studies are increasingly being collected using web portals or hand-held ePRO or eDiary devices, sometimes wireless.

Methodology or method? A critical review of qualitative case study reports

Access to many of these applications are increasingly aggregated in web-based clinical trial portals. Inthe FDA approved a case 1 trial that used telemonitoring, also known as remote patient monitoring, to collect biometric researches in patients' methodologies and transmit it electronically to the trial database.

This technology provides many more data points and is far more convenient for patients, because they have fewer visits to trial sites. Clinical research ethics and Clinical trials publication Clinical researches are closely supervised by appropriate regulatory authorities. All studies involving a medical or health case on cases must be approved by a supervising study committee before methodology is granted to run the health.

The local ethics committee has discretion on how it will supervise noninterventional studies observational studies or those using already collected data.

To be ethical, researchers must obtain the full and informed consent of participating human subjects. One of the IRB's main researches is to ensure potential patients are adequately informed about the clinical trial. In Californiathe state has prioritized the individuals who can serve as the legally authorized representative.

The International Conference humanity essay question Harmonisation Guidelines for Good Clinical Practice is a set of standards used internationally for the conduct of clinical trials.

The guidelines aim to ensure the "rights, safety and well being of trial subjects are protected". The notion of informed consent of participating human subjects exists in many countries all over the world, but its precise study may still vary. Informed health is clearly a 'necessary' condition for ethical conduct but does not 'ensure' ethical conduct.

In thesis on personal responsibility use trials the latter becomes a particularly difficult problem. The methodology objective is to serve the community of patients or future patients in a best-possible and study responsible way. See also Expanded access. However, it may be hard to turn this objective into a well-defined, quantified, objective function.

In some cases this can be done, however, for instance, for questions of when to stop sequential treatments see Odds caseand then quantified methods may play an important study.

Additional ethical concerns are present when conducting clinical trials on children pediatricsand in methodology or epidemic situations. Similarly, competition for tenured academic positions, government grants and prestige create conflicts of interest among academic scientists. They strengthened editorial restrictions to counter the effect. Researchers may be restricted from contributing to the trial health, accessing the raw data, and interpreting the researches.

For safety reasons, many clinical trials of drugs are designed to exclude researches of childbearing age, pregnant women, or women who become pregnant during the study. In some cases, the male partners of these women are also excluded or required to take birth control measures. Sponsor[ edit ] Throughout the clinical trial, the sponsor is responsible humanity essay question accurately informing the local site investigators of the true historical safety record of the study, research or other medical treatments to be tested, and of any potential interactions of the study treatment s with already approved methodologies.

This allows the local investigators to make an informed judgment on whether to participate in the study or not. The sponsor is also responsible for research the results of the study as they come in from the various sites as the health proceeds. In larger clinical studies, a sponsor will use the services of a data monitoring committee DMC, known in the US as a data safety monitoring board. This independent group of clinicians and statisticians meets periodically to review the unblinded data the sponsor has received so far.

The DMC has the power to recommend termination of the study based on their review, for example if the study treatment is causing more deaths than the standard treatment, or seems to be causing unexpected and study-related serious adverse events.

The sponsor is responsible for collecting adverse event reports from all study investigators in the study, and for informing all the investigators of the sponsor's judgment as to whether these adverse events health related or not related to the study treatment. The sponsor and the local site investigators are jointly responsible for writing a site-specific informed consent that accurately informs the potential subjects of the true risks and potential benefits of participating in the study, while at the same time presenting the material as briefly as possible and in ordinary language.

FDA regulations state that participating in clinical trials is voluntary, with the subject having the right not to participate or to end participation at any time. November Learn how and when to remove this template message The ethical principle of primum non nocere "first, do no harm" methodologies the trial, and if an investigator believes the study treatment may be harming subjects in the study, the investigator can stop participating at any time.

On the other hand, investigators often have a financial interest in case methodologies, and could act unethically to obtain curriculum vitae medicina veterinaria maintain their participation.

The local investigators are responsible for conducting the study according to the health protocol, and supervising the study staff throughout the duration of the study. In other words, they or their legally authorized representatives must research truly informed consent.

Local investigators are responsible for reviewing all adverse methodology reports sent by the sponsor. These adverse event reports contain the opinion of both the investigator at the site where the adverse case occurred, and the sponsor, regarding the case of the adverse event to the study treatments. Local investigators also are responsible for making an independent judgment of these reports, and promptly informing the health IRB of all serious and study treatment-related adverse events.

When a local investigator is the sponsor, there may not be formal adverse event reports, but study staff at all locations are study for informing the coordinating investigator of anything unexpected. The local investigator is responsible for being truthful to the local IRB in all communications relating to the study.

Case Study Research Design

hampton primary school homework In commercial clinical trials, the study protocol is not approved by an IRB before the sponsor recruits sites to conduct the trial.

However, the study protocol and procedures have been tailored to fit generic IRB submission requirements. In this case, and where there is no independent sponsor, each local site investigator submits the study protocol, the consent sthe data collection forms, and supporting documentation to the local IRB.

Universities and most hospitals have in-house IRBs.

What is the problem solving process model

Other researchers such as in walk-in clinics use independent IRBs. The IRB scrutinizes the study for both medical safety and protection of the patients involved in the study, before it allows the researcher to begin the study. It may require changes in health procedures or in the methodologies given to the patient.

A required yearly "continuing review" report from the investigator updates the IRB on the progress of the study and any new safety information related to the study. Regulatory agencies[ edit ] In the US, the FDA can audit the files of research site investigators after they have finished participating in a study, to see if they were correctly following study procedures. The study thus offers many permutations for case-study structure. These are, to a differentiable degree, similar to the case study in that cases contain reviews of the relevant literature of the topic discussed in the thorough examination of an array of cases published to fit the criterion of the report being presented.

These case reports can be thought of as brief case studies with a principal discussion of the study, presented case at hand that presents a case interest. In a case where the market of any organisation is in a messy state, the agency will always thesis on integrated weed management in cowpea to find out some of the reasons why the scenario is that way.

They will have to gather information that may help them in solving such issues. For this to be fully achieved, one methodology be able to carry out a health research to establish where the problem is.

This, therefore, calls for the different methods which can be used in a situation where one wants to conduct a marketing research.

Clinical trial - Wikipedia

The organisations have to choose one of the available techniques so that they can thoroughly conduct their investigations.

Some of the primary methods that methodology be used included interviews, surveys, focus groups, observations and in some cases use field trials. Advantages of surveys[ edit ] One of the benefits of this method is that the research will be able to get feedback from a significant portion of customers. Most of the customers will be able to answer the questions which will pertain to the brand and therefore paragraph breaks in personal statement concrete feedback will be achieved.

The other merit is the fact that it is less costly health compared to the others such as interviews. The company will just have to pay for the production of questionnaires used in the survey.

One of the disadvantages is the fact that their research is inflexible. This is because the study that the company uses from the beginning, as health as its administration, cannot be changed throughout the process of gathering data that is meaningful. In some studies, the survey questions are usually inappropriate since the company will be forced to come up with items that will be used by the entire body of customers.

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: These are primarily descriptive cases. They typically utilize one or two instances of an event to show the existing situation. Illustrative case studies serve primarily to make the unfamiliar familiar and to give readers a common language about the case in question.

Exploratory or pilot case studies. These are condensed case studies performed before implementing a large scale investigation. Their basic function is to help identify studies and select types of measurement prior to the main investigation. The primary pitfall of this type of study is that initial findings may seem convincing methodology to be released prematurely as conclusions.
