Different Methods for Evaluating Evidence Essay

This is a very informative post. You have clearly outlined, compared, and contrasted systematic review and randomized controlled trial as the methods used for evaluating evidence. The two methods that you choose are very important when evaluating evidence. It is impressive you have clearly explained that systematic reviews synthesize the findings from multiple studies in a certain area (Rajab et al., 2019). I would like to add that, systematic reviews belong to the highest level of the hierarchy of evidence as they provide the best evidence for all kinds of questions because they are based on findings and results from many studies identified during comprehensive and systematic literature search (Naidoo et al., 2020). You have also clearly outline randomized controlled trials (RTCs) as a method that randomly allocated participants to groups. RTCs belong to the second level of the hierarchy of evidence. It is quite impressive that you have discussed the two most reliable methods of evaluating evidence. Systematic reviews and RTCs provide the best and high-quality evidence. Therefore, evidence from both systematic reviews and RTCs can be very useful in informing change practices and quality improvement initiatives in healthcare organizations due to their high-quality evidence. It is important to ensure the evidence is obtained from the latest available systematic reviews and RTCs.

Topic 3 DQ 2

Name two different methods for evaluating evidence. Compare and contrast these two methods.

Re: Topic 3 DQ 2

There are different methods for evaluating evidence. One of them is a systematic review, which is a summary of the clinical literature. A systematic review is a critical assessment and evaluation of all research studies that address a particular clinical issue. The researchers use an organized method of locating, assembling, and evaluating a body of literature on a particular topic using a set of specific criteria. A systematic review typically includes a description of the findings of the collection of research studies. The systematic review may also include a quantitative pooling of data, called a meta-analysis. For Example, complementary and alternative medicine use among women with breast cancer, which is a systematic review(GSU,2020).

Another method of evaluating evidence is the randomized controlled trial. A controlled clinical trial is one which that randomly assigns participants to two or more groups. There are various methods to randomize study participants to their groups. For Example, meditation or exercise for preventing acute respiratory infection which is a randomized controlled trial(GSU,2020).
