Evidence
Evidence is a foreign word derived from the English word meaning proof, evidence, or testimony. In the field of medicine, it refers to scientific evidence that determines whether a medicine, treatment method, or test method is "effective," "ineffective," "appropriate," or "inappropriate," among others.
Medicines, treatment methods, and testing methods are actually used by a large number of patients to study their effectiveness and safety. A study is considered reliable evidence when multiple studies point to similar results. Evidence is scientific proof derived from the accumulation of such studies.
The word "evidence" is derived from the English word "evidence," meaning proof, basis, or testimony. It is not a technical term limited to the medical field, but is used in a variety of fields. In the medical field, it is used to ask questions such as "Is the treatment based on evidence? In these situations, evidence refers to scientific proof that the treatment can be said to be good.
Evidence is created by conducting clinical research/trials and trials. Drugs, treatments, and testing methods are studied in healthy people or patients through Clinical research / clinical trials, clinical trial Clinical trials are conducted on healthy people or patients to determine the extent to which a drug, treatment, or test has or does not have side effects, is superior to existing drugs or methods, or is safe. Even after clinical trials have concluded that a drug can be used widely in the world, there are patients with various conditions and conditions in actual clinical settings, so research continues to be conducted to answer various questions.
Also, there are levels of evidence. Not all studies and trials of any kind can be conducted with perfect precision, and various factors can lead to a certain level of Bias The results of any study or trial cannot be conducted with perfect precision and may contain a certain amount of bias due to various factors. The level of evidence is a measure of the degree of confidence in the accuracy and reliability of the results. For example, if the results of multiple studies with high precision all show similar results, the level of evidence for the effectiveness or safety of a drug, treatment, or test method is considered high and reliable. On the other hand, reports of individual patient conditions or personal opinions that are not based on specific patient treatment data are considered to have a low level of evidence. The level of evidence is, Clinical Practice Guidelines The level of evidence is used to determine the level of treatment recommendations, which are also listed in medical practice guidelines.
Medical professionals, patients, and other stakeholders are in a position to use the evidence created in this way. One organization that serves as a link between the creators and users of evidence is the Cochrane Network. Cochrane is an international non-profit organization based in the UK that summarizes the results of research on various diseases and treatments and communicates highly reliable evidence on health.
Today's medicine emphasizes the concept of evidence-based medicine (EBM), which is based on objective facts confirmed by the latest research and clinical trial data, rather than relying on subjective judgments based on a doctor's experience. EBM does not rely on subjective judgments based on a physician's experience, but on objective facts confirmed by the latest research and clinical trial data.
