A hierarchy of evidence, comprising levels of evidence (LOEs), that is, evidence levels (ELs), is a heuristic used to rank the relative strength of results obtained from experimental research, especially medical research. There is broad agreement on the relative strength of large-scale, epidemiological studies.
The evidence used to change practice or make a clinical decision can be separated into seven levels of evidence that differ in type of study and level of quality. To properly implement EBN, the knowledge of the nurse, the patient's preferences, and multiple studies of evidence must all be collaborated and utilized in order to produce an ...
The CCC System consists of discrete atomic-level data elements that encompasses nursing diagnoses, interventions, and outcomes. The CCC is a nursing terminology specifically developed for computerization: e.g. electronic healthcare information systems (EHR), computer-based patient records (CPR), and Clinical Information Systems (CIS), from ...
A nursing diagnosis may be part of the nursing process and is a clinical judgment about individual, family, or community experiences/responses to actual or potential health problems/life processes. Nursing diagnoses foster the nurse's independent practice (e.g., patient comfort or relief) compared to dependent interventions driven by physician ...
Another example are the Oxford CEBM Levels of Evidence published by the Centre for Evidence-Based Medicine. First released in September 2000, the Levels of Evidence provide a way to rank evidence for claims about prognosis, diagnosis, treatment benefits, treatment harms, and screening, which most grading schemes do not address.
NANDA International (formerly the North American Nursing Diagnosis Association) is a professional organization of nurses interested in standardized nursing terminology, that was officially founded in 1982 and develops, researches, disseminates and refines the nomenclature, criteria, and taxonomy of nursing diagnosis. In 2002, NANDA became NANDA ...
The GRADE approach separates recommendations following from an evaluation of the evidence as strong or weak. A recommendation to use, or not use an option (e.g. an intervention), should be based on the trade-offs between desirable consequences of following a recommendation on the one hand, and undesirable consequences on the other.
CEBM has developed a widely adopted [6] systematic hierarchy of the quality of medical research evidence, named the levels of evidence. Systematic reviews of randomised clinical trials (encompassing homogeneity) are seen as the highest possible level of evidence, as full assessment and aggregated synthesis of underlying evidence is possible.
