Issued by third-party organizations, and not NCCIH, these guidelines define the role of specific diagnostic and treatment modalities in the diagnosis and management of patients. The statements contain recommendations that are based on evidence from a rigorous systematic review and synthesis of the published medical literature.

What is evidence-based medicine and clinical guidelines?
Evidence-based medicine focuses on research dealing with the day-to-day practice of patient care. The evidence may prove or disprove previously accepted methods or demonstrate new ways of care that are more accurate and effective and less harmful. Evidence-based medicine also recognizes that the research literature is constantly changing.

What is the evidence-based protocols module?
Clinical guidelines have become widely available across the practice of medicine; many specialty societies have published such guidelines. Most well-conceived clinical guidelines are developed using a specified method that incorporates principles of EBM and consensus or Delphi process recommendations made by a panel of experts.

What is evidence-based practice in medicine?
The practice of evidence-based medicine is a process of lifelong, self-directed, problem-based learning in which caring for one's own patients creates the need for clinically important information about diagnosis, prognosis, therapy and other clinical and health care issues.

What are healthcare protocols?
In a healthcare setting, a protocol, also called a medical guideline, is a set of instructions which describe a process to be followed to investigate a particular set of findings in a patient, or the method which should be followed to control a certain disease.
How is evidence-based practice used in healthcare?
Evidence-based practice is the “integration of best research evidence with clinical expertise and patient values.” It means that when health professionals make a treatment decision with their patient, they base it on their clinical expertise, the preferences of the patient, and the best available evidence.Nov 7, 2013
What is an example of evidence-based practice in healthcare?
Through evidence-based practice, nurses have improved the care they deliver to patients. Key examples of evidence-based practice in nursing include: Giving oxygen to patients with COPD: Drawing on evidence to understand how to properly give oxygen to patients with chronic obstructive pulmonary disease (COPD).
What is evidence based medicine?
However, for many clinicians, the “evidence” is often a vague combination of recollected strategies effective in previous patients, advice given by mentors and colleagues, and a general impression of “what is being done” based on random journal articles, abstracts, symposia, and advertisements. This kind of practice results in wide variations in strategies for diagnosing and managing similar conditions, even when strong evidence exists for favoring one particular strategy over another. Variations exist among different countries, different regions, different hospitals, and even within individual group practices. These variations have led to a call for a more systematic approach to identifying the most appropriate strategy for an individual patient; this approach is called evidence-based medicine (EBM). EBM is built on reviews of relevant medical literature and follows a discrete series of steps.
Why is significant judgment required when applying results from a randomized trial to a specific patient?
Because the best available evidence may have come from patient populations with different characteristics from those of the patient in question, significant judgment is required when applying results from a randomized trial to a specific patient. Additionally, patients’ wishes regarding aggressive or invasive tests and treatment must be taken into account as well as their tolerance for discomfort, risk, and uncertainty. For example, even though an EBM review may definitively show a 3-month survival advantage from an aggressive chemotherapy regimen in a certain form of cancer, patients may differ on whether they prefer to gain the extra time or avoid the extra discomfort. The cost of tests and treatments may also influence physician and patient decision making, especially when some of the alternatives are significantly costlier for the patient. Two general concerns are that patients who voluntarily participate in clinical trials are not the same as patients in general practice, and care delivered in a clinical trial environment is not identical to general care in the medical community.
What are guidelines and algorithms?
Guidelines and algorithms are generally straightforward and easy to use but should be applied only to patients whose clinical characteristics (eg, demographics, comorbidities, clinical features) are similar to those of the patient group used to create the guideline.
Is clinical trial the same as general practice?
Two general concerns are that patients who voluntarily participate in clinical trials are not the same as patients in general practice, and care delivered in a clinical trial environment is not identical to general care in the medical community.
What is evidence based guidelines?
Evidence-based guidelines--an introduction. Recommendations in the form of clinical practice guidelines are increasingly common. Clinical guidelines are systematically developed statements designed to help administrators, practitioners and patients make decisions about appropriate health care for specific circumstances.
What is clinical practice guidelines?

What are guidelines used for?
In North America, guidelines developed by professional societies, government panels and cooperative groups are frequently used to measure quality, to allocate resources and to determine how health care dollars are spent.
How do systematic reviews help evaluate studies?
Systematic reviews can help evaluate the studies by posing a focused clinical question, identifying every relevant study in the literature, evaluating the quality of these studies by using predetermined criteria, and answering the question based on the best available evidence.
Why are randomized controlled trials not available?
In one study, randomization was in blocks of four, so one person in each block was randomized to one of the four treatment protocols. Because of ethical constraints, randomized controlled trials will not be available to answer all clinical questions, particularly those that explore long-term risks, such as cancer.
What is the SMD of a group?
The SMD is calculated as the difference in the mean outcome between groups divided by the standard deviation. In general, an SMD less than 0.2 is not clinically significant, an SMD of 0.2 represents a small clinical effect, an SMD of 0.5 is a moderate effect, and an SMD of 0.8 or greater is a large effect.
What does 1.0 mean in a relative risk?
A relative risk of 1.0 indicates that the exposure does not change the risk of disease.
When does concealment take place in a study?
Allocation concealment takes place before the study begins, as patients are being assigned. Blinding or masking—concealing the study group assignment from those participating in the study—occurs after the study begins. Blinding should involve the patient, the physicians caring for the patient, and the researcher.
Is it better to publish negative or positive studies?
Negative studies are less likely to get published than positive studies, and this results in the overwhelmingly positive nature of the literature. Even when negative studies are published, they are less likely to receive the attention by the media and medical establishment that positive studies do.
What is evidence based medicine?
Evidence-based medicine, whose philosophical origins extend back to mid-19th century Paris and earlier, is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients.
Can a doctor use external evidence alone?
Good doctors use both individual clinical expertise and the best available external evidence, and neither alone is enough. Without clinical expertise, practice risks becoming tyrannized by external evidence, for even excellent external evidence may be inapplicable to or inappropriate for an individual patient.
