Discussion- Each source under review has some degree of relevancy for nursing. However, each source is also segmented for a different audience and level of competence. The Clinical Practice Guidelines and the portion of the text by Kelley are good basic introductory reviews. Someone with a basic understanding of physiology and medicine...
The Block and McCracken research, though, are both the most verifiable, current, and scientific. Both Block and McCracken are peer-reviewed articles, using standard research methodologies that address a specific clinical issue. They use sound principles of research, have thorough literature reviews, good sample selections, and are written and developed in a way that would be relevant to anyone involved in clinical practice. The use of anecdotal evidence, though, is problematical in a professional situation. Particularly when dealing with medical or other personal issues, divergent people have divergent views. When dealing with a group of mother's, for instance, who have anecdotal evidence about their child's medical issue; it is easy to extrapolate their issues into broad categories. However, in the medical field, both best practice and evidence-based guidelines require that material be scholarly and follow standard principles of scientific research.
Part B -- The article Diagnosis and Management of Acute Otitis Media proposes a medical philosophy called Watchful Waiting. The basic idea is that it is not always critical to immediately medicate with strong antibiotics, etc. In some cases. In the case of AOM, there are of course differences regarding age, severity, complications and if chronic. However, the research suggests that it is advisable to wait 48-72 hours before prescribing antibiotics. During this period it is, though, advisable to treat symptoms (fever, chills, discomfort, etc.). Rest has been shown to be one of the best ways toward recovery for children, particularly if discomfort is treated (Glaszhou, et al., 2004).
Part C - Further, the data shows that in most cases AOM infections are not bacterial and thus, impervious to antibiotics. This does not mean that antibiotics would never be used, but only that they are used appropriately instead of blindly. Instead, evidence-based practice suggests that the healthcare professional should: 1) Review and confirm the diagnosis of AOM; determine if chronic or not. If the…
