Regarding step 4, they consider that the answer to the review question is the answer most commonly given by the included publications, when greater weight is given to answers based on higher-scoring reasoning.

The eligibility criteria should identify all and only publications that include the reasons mentioned by the review question.

Systematic reviews undertake this substantial task and answer the question in a form accessible to decision-makers. Reviewing the literature is a scientific inquiry that needs a clear design to preclude bias. Some people dislike Maastricht because it seems to stand for the ideal of the United States of Europe, but many of us in Maastricht do not even know what the treaty is about.

For example, our eligibility criteria were: Firstly, large quantities of information must be reduced into palatable pieces for digestion. Clearly, systematic literature review is needed to refine these unmanageable amounts of information.

People in my town are very inventive in finding reasons for painting the town red. It included a reason why PTA should or need not be provided; The PTA was for former participants in a drug trial; The PTA was to a drug tested in the trial; and The publication was a peer-reviewed, published academic article or book; national-level report or working paper; or PhD thesis.

Model for writing systematic reviews of reasons Formulate the review question and eligibility criteria A tentative general form of review question is: This article gives examples of systematic reviews on vitamin C and the common cold, pyridoxine against the premenstrual syndrome, homeopathy, and physiotherapy.

A review of reasons cannot guarantee to accomplish this for them: The difference is likely to be marked when a literature is large, fragmented across disciplines and literary genres, and indexed in databases inadequately and inconsistently, as bioethics literatures often are.

Database-specific search strings will be needed. Often a mixture of controlled and non-controlled vocabulary can help to adjust the sensitivity and specificity of search strings. Finally explicit methods used in systematic reviews limit bias and, hopefully, will improve reliability and accuracy of conclusions.

Systematic Reviews: Rationale for systematic reviews

Our systematic review showed differences between publications on the cost, legality and logistics of ensuring PTA, and suggested that many factual claims were not evidence based.

Bioethicists as well as clinical and policy decision-makers are less likely, we surmise, to understand the significance of limitations in reasoning than in study design. Identify all of the literature that meets the eligibility criteria.

You will have heard of Maastricht - in the European Union treaty was signed there. Systematic literature review is a fundamental scientific activity. Through critical exploration, evaluation, and synthesis the systematic review separates the insignificant, unsound, or redundant deadwood in the medical literature from the salient and critical studies that are worthy of reflection.

A systematic review of reasons is likely to reveal a greater range of such information than the informal reviews of reasons that are usual in bioethics and philosophy, which sample literature using unsystematic, undocumented search methods to the unspecified point at which it seems to the author often the only author that no relevant new reasons emerge.

Systematic Reviews: Some examples

Box 1 Four steps for writing a systematic review Formulate the review question and eligibility criteria. Publications arguing that X is not required may hold that X is permissible or forbidden; as we note later, the analysis should be sufficiently sensitive to distinguish between these positions.

Some have recently advocated applying the genre to argument-based literature in clinical and research ethics, and in bioethics generally, again to improve decision-making, and there have been two such applications. Nearly every good carnivalist gets a sore throat, a stuffy nose, and other signs of a common cold: It is a real enterprise if one aims at completeness of the literature on a certain subject.

Health care providers, researchers, and policy makers are inundated with unmanageable amounts of information; they need systematic reviews to efficiently integrate existing information and provide data for rational decision making. The rationale for such reviews is well established.

Going through refereed English language journals is not enough. I immediately thought of making it a carnival trial. To date, however, the assessment of the quality of reasons and of argument-based literature is much less standardised than, for example, the assessment of the quality of clinical trials and the literature that reports their results.

We agree with McCullough et al 9 that clinicians could benefit from systematic reviews of clinical ethics literature. Systematic reviews are used by more specialised integrators, such as economic and decision analysts, to estimate the variables and outcomes that are included in their evaluations.Downloaded from on January 18, - Published by Teaching and learning ethics PAPER How to write a systematic review of reasons Daniel Strech,1 Neema Sofaer2.
