Explanation (1 paragraph description of WHY you ranked the sources this way):

To evaluate the credibility of online information sources I used Metzger’s criteria of accuracy, authority, objectivity, currency and coverage (Metzger, 2007). I ranked the peer-reviewed journal articles on the top because these articles are published after going through various sets of tests and they are reviewed and approved by people of expertise from within that industry. This makes them an extremely reliable source of information. I ranked e-books second because they are credible, have authority and coverage so I got in-depth information about my topic from these. The website I used was the Australian Government’s Department of Health website and it provided detailed figures and surveys about the prevalence of MRSA in Australia so this was a reliable and helpful source. The newspaper articles I found were helpful because they explained the topic in layman’s terms and were easier to comprehend. I have ranked TV and Blogs at the end because they lacked objectivity and accuracy so they were not credible sources.

Portfolio Activity 5: Evaluating journal articles/ A Review of the Literature Select the most relevant journal article found in your search above and perform an indepth review (approximately 300 words) by providing the following information:

1. Provide the full reference of the article you have chosen. 2. Comment on the quality of the publication. (1 paragraph) 3. Comment on the nature of the research design. (1 paragraph) 4. Comment on the research strength and limitations. (1 paragraph)

Naimi, T. S., LeDell, K. H., Como-Sabetti, K., Borchardt, S. M., Boxrud, D. J., Etienne, J., ... & Lynfield, R. (2003). Comparison of community-and health care– associated methicillin-resistant Staphylococcus aureus infection. Jama, 290(22), 2976-2984. doi:10.1001/jama.290.22.2976

The metrics I used for analyzing the quality of the article were to check the credentials of the authors, reputation of the publisher, currency of the article and coverage. This article was published in 2003 in The Journal of the American Medical Association (Vol 290, No. 22). The JAMA is a reputable peer-reviewed medical journal that publishes articles about diverse topics in biomedical sciences. The authors of this article are affiliated with highly-esteemed institutions and have excellent credentials. Although the article is not current but it is relevant to my focus areas. It was the “first prospective comparison” (Naimi et al., 2003, p. 2981) of community-associated and healthcare-

associated MRSA in United States so it gives us the perspective from that time.

The research design was a longitudinal cohort study in which over the course of one year the patients with MRSA-infection were compared. The objectives of the study were met, and the research design and settings show that appropriate measures were taken to avoid biasness. Appropriate laboratory and statistical methods are used and they are explained thoroughly which makes the research testable and repeatable.

One of the strengths of this research is that it was performed at multiple sites in different geographic locations within Minnesota so it covered a wide range (Naimi et al., 2003, p. 2982). It was also the first of its kind to attempt to get MRSA isolates from all reported cases. One of the limitations of this research was that the average age of communityassociated MRSA patients was 23 while that of the healthcare-associated MRSA patients was 68 years which made the comparison questionable. The article also acknowledges its limitation that the study was sample-based rather than populationbased so it may not be representative of all the cases that occurred in Minnesota.
