Methods of Documentation V: CBE01:23

Methods of Documentation V: CBE

Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...
The Scientific Method in Nursing Process01:18

The Scientific Method in Nursing Process

The scientific method provides the foundation for any research. It is the most reliable and objective of all forms of gaining knowledge and guides in applying research-based evidence in practice and conducting future research.
When using research findings to change practice, one must understand the process used to guide a study. The scientific method is a systematic, step-by-step process that supports the data's validity, reliability, and generalizability. As a result, findings can be safely...
The Evidence for Evolution02:55

The Evidence for Evolution

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.The collection of fossils within sedimentary rocks give a record of common ancestry and often depicts the history of evolution.
Nursing Clinical Information System01:27

Nursing Clinical Information System

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...

Area of Science:

  • Philosophy of Science
  • Medical Research Methodology
  • Clinical Epidemiology

Background:

  • Evidence-based medicine (EBM) utilizes a hierarchy of evidence to assess therapeutic decision reliability.
  • This hierarchy prioritizes randomized interventional studies over observational data and clinical experience.
  • Recent philosophical critiques question the justification for EBM's emphasis on randomization.

Purpose of the Study:

  • To critically examine the philosophical underpinnings of the EBM hierarchy of evidence.
  • To evaluate the arguments for and against the privileged status of randomized controlled trials.
  • To propose a revised justification for the hierarchy based on comparative internal validity.

Main Methods:

  • Philosophical analysis of existing arguments in EBM literature.
  • Engagement with critical philosophical perspectives, particularly John Worrall's work.
  • Reinterpretation of the hierarchy of evidence as a measure of comparative internal validity.

Main Results:

  • Agrees with critiques that many EBM arguments for randomization's superiority are insufficient.
  • Proposes a novel justification for the hierarchy of evidence.
  • Identifies the hierarchy as reflecting comparative internal validity.

Conclusions:

  • A defensible justification for the EBM hierarchy of evidence exists.
  • This justification frames the hierarchy as a measure of comparative internal validity.
  • The scope of claims supported by the hierarchy is more limited than often asserted in EBM literature.
