In a simple and straightforward meaning, the term Evidence simply refers as a testimony and presentation of documents, records, objects, and other such items relating to the existence or non-existence of alleged or disputed facts into which a court enquires. The rules and regulations that conduct and preside over the formation of a detail before a court, jointly called the act of evidence. Evidence submits to all that is normally used to ascertain and reveal the fact of an statement whereas evidence based practice is one of the interdisciplinary method usually applied in the area of medicine such as nursing, psychiatry, neurology, obstetrics and gynaecology, paediatrics including neonatology, pathology which includes toxicology, emergency medicine, pharmacology, and so on. So, evidence based practice follows the fundamental rule which is affirmed as all the common practical evaluation should be prepared according to the approved research studies which should be chosen and explained as per some standards and feature for evidence based practice. In health care system, Evidence based practice refers to all the clinical judgments that are prepared on the basis of investigation and scientific studies which facilitates in the distribution of the high quality care to the patient to make better results. Evidence-based health care practices are accessible for a number of circumstances such as diabetes, heart failure, kidney failure, and asthma. Nevertheless, these practices are not continuously put into practice in care delivery, and discrepancy in practices proliferate. By tradition, patient protection study has concentrated on data analysis to identify patient protection issues and to exhibit that a new practice will guide to improved quality and patient protection. Executing evidence-based protection practices are complicated and require plan that deals with the difficulty of care systems, individual practitioners, senior leadership, and eventually altering health care traditions to be evidence-based protection practice environments.
There is a great history of practice in nursing field by means of research, initiated by Florence Nightingale. Although for the period of early and mid-1900s, a small number of nurses played a role to this establishment commenced by Nightingale. Through application of research findings in practice, there has been in recent times granted a major control in nursing profession for getting better care. Evidence-based practice (EBP) is the careful and sensible use of the most excellent proof in combination with clinical expertise and patient values to conduct health care conclusions. Observing evidence from randomized controlled trial (RTC) (or randomized comparative trial) which is a specific type of scientific experiment; evidence from other technical approaches like illustrative and qualitative research; as well as utilization of knowledge from technical assumptions, opinion from expertise of the same field, and case reports are the best evidences which support in development of the health care. As soon as there has been an enough evidences from research, the practice should be directed by research evidence in combination with patient values and medical proficiencies. Health care decision making is obtained predominantly from non-research evidence basis like opinion from expert and technical supports. This type of decision is made only when there is lack of sufficient research. As more research is prepared in a particular area, the research evidence must be integrated into the evidence based practice as a tool for the future reference.
