Can I suggest questions that I would like to see answered?

If you have a question that suits our format, which we have not examined, please contact us. We will take it into consideration for future issues.

What sorts of questions are covered?

The clinical questions concern the benefits and harms of preventative and therapeutic interventions, with emphasis on outcomes that matter to patients.

How do you select the questions?

Clinical questions are selected for their relevance to clinical practice by section editors and contributors, in collaboration with primary care clinicians and patients. Consultation rates, morbidity and mortality data are also consulted to ensure that important conditions are included.

How do you choose which treatments to cover?

Before deciding on the treatment for any patient or group of patients, other information needs to be considered together with the information on effectiveness provided here. Examples include economic arguments, patient preferences, and their different levels of baseline risk.

Which databases do you search?

The literature is searched using the Cochrane Library, Medline, Embase, and occasionally other electronic databases, looking first for good systematic reviews and then for primary studies with designs that are most appropriate for answering the question.

How do you filter out poor quality studies?

Systematic reviews and individual studies are critically and independently appraised by a clinician and an information specialist for relevance and quality, using a validated criteria similar to those of Sackett et al and those of Jadad. This process means that not all randomised controlled trials or reviews are included. The studies are then also filtered by the author for clinical relevance.

How do you ensure that the information is of high quality?

Each topic is peer reviewed by the section editor, at least two external expert peer reviewers, by members of the advisory board, and by an international editorial committee of generalist clinicians with expertise in epidemiology.

How does Clinical Evidence differ from clinical guidelines?

Unlike clinical practice guidelines, Clinical Evidence specifically aims not to make recommendations. The experience of the clinical guideline movement has shown that is near impossible to make recommendations that are appropriate in every situation. Clinical Evidence provides the raw material for developing locally applicable clinical practice guidelines. BMJ Clinical Evidence reports the current state of the available evidence, and where there are gaps it says so.

How is it different from the Cochrane Library?

The Cochrane Library is a vital building block for Clinical Evidence, but Clinical Evidence comes a few steps nearer to the realities of clinical practice. Clinical Evidence begins with the questions and then looks for the evidence addressing those questions.

How is it different from Evidence-Based Medicine?

Clinical Evidence is different from Evidence-Based Medicine because it is driven by important clinical questions. Evidence-Based Medicine (and other evidence-based journals) review research as it is published in clinical journals. Both these publications are, however, intended to compliment one another.
