Describe the influence “levels of evidence” have on practice changes. Identify the most reliable level of evidence and provide an example of the type of practice change that could result from this level of evidence.
Initial discussion question posts should be a minimum of 200 words and include at least two references cited using APA format. Responses to peers or faculty should be 100-150 words and include one reference. Refer to “RN-BSN Discussion Question Rubric” and “RN-BSN Participation Rubric,” located in Class Resources, to understand the expectations for initial discussion question posts and participation posts, respectively.
Understanding the “levels of evidence” is crucial in healthcare as it directly impacts decision-making and practice changes. Evidence-based practice (EBP) relies on these levels to assess the reliability and strength of available information. The levels of evidence are typically categorized on a scale, ranging from expert opinions and anecdotal evidence at the lower end to systematic reviews and meta-analyses at the higher, more reliable end.
The influence of these levels on practice changes is substantial. Higher levels of evidence, like systematic reviews and meta-analyses, offer more reliable and comprehensive assessments of various studies, leading to greater confidence in the conclusions drawn. For instance, a meta-analysis demonstrating the effectiveness of a specific medication in lowering blood pressure is a strong piece of evidence that can prompt a change in prescribing practices among healthcare providers.
However, the most reliable level of evidence is often considered to be systematic reviews and meta-analyses. These synthesize multiple studies, applying rigorous methodologies to draw more robust conclusions than individual studies alone. Consequently, they hold significant weight in guiding practice changes. An example would be a meta-analysis showing the efficacy of a certain therapy in reducing the recurrence rate of a particular type of cancer. This could prompt oncologists to update their treatment protocols, adopting this therapy as a standard practice for their patients.

When it comes to responding to peers, acknowledging the significance of these higher levels of evidence and their impact on practice changes can further the discussion. Supporting their insights with additional references or real-world examples can add depth to the conversation.
