Re:Topic 4 DQ 2
The internet opens up a vast world of information. The value of the internet and its information can be overwhelming and also invalid. Just because the internet says something does not make it true or valid. Researchers scientists physicians and nurses must critically review and analyze research-based information to evaluate validity before applying it to daily practice.
Assessing research takes place by evaluating the levels of evidence being used by examining the quality of the study done. Evaluating the level of evidence and then critiquing the study is the only way to validate the results are accurate and true. The most reliable way to rate evidence of research is by the design of the study.According to the 2012 American Association of Critical-Care Nurse’s levels of evidence with revisions to 2008 hierarchy the best evidence to direct clinical practice and protocols includes: 1. Meta-analysis or meta-synthesis of multiple controlled studies with results that consistently support a specific action intervention or treatment (systematic review of a randomized controlled trial)
2. Evidence from well-designed controlled studies both randomized and nonrandomized with results that consistently support a specific action intervention or treatment
3. Evidence from qualitative integrative reviews or systematic reviews of qualitative descriptive or correlational studies or randomized controlled trials with inconsistent results
4. Evidence from peer-reviewed professional organizational standards with clinical studies to support recommendations
5. Theory-based evidence from expert opinion or multiple case reports
6. Manufacturers recommendation only (Peterson et al. 2014 p. 60).
Evidence from a meta-analysis randomized controlled trials and systematic reviews are all experimental and are the type of evidence used to develop clinical practice guidelines and protocols. Meta-analysis and systematic reviews are many times used as the foundation for creating clinical protocols and keeping clinicians up to date on the new advances made in their fields. A systematic review is a structured comprehensive synthesis of the research literature to determine the best research evidence available to address a healthcare question. A systematic review involves identifying locating appraising and synthesizing quality research evidence for expert clinicians to use to promote EBP (Grove Gray & Burns 2015 p. 462).
Evidence from peer reviews expert opinion and manufacturers recommendations are non-experimental data collected and analyzed but not to develop a treatment or intervention for a specific outcome.The purpose of an evidence rating system is to assist all clinicians on making the decision to move practice suggestions into real practice protocols delivered at the bedside. All clinicians are responsible for making sure their practice is an evidence-based practice that has studies and research to back it up.
