1. Describe three unique features of PubMed database that sets this database apart from other evidence-based search engines.

2. Compare and contrast two additional databases and reference your selected topic, by using the Cochrane Collaboration and Medline as your search engines.

3. Determine how you applied the three key questions when deciding which database to use.

The PubMed database is a unique tool to help the practitioner search and find reliable and valid results with less effort. Two features of the database are its ability to differentiate the priority of search terms in the results list using MeSH terms, and to manipulate the search algorithms to help the practitioner answer clinical questions (Chapman, 2009). These tasks are accomplished by additional options tabs during navigation of the search functions. Another unique feature of PubMed is the use of a sub database called Entrez, which is a text search and retrieval system that incorporates the database into thirty-eight other databases to increase the ability for precise search results (Entrez Help, 2016). This addition separates PubMed from other databases by allowing for more layers of refinement of searches conducted to increase the likelihood of finding exactly what the researcher is looking for.

In contrast, the Cochrane Collaboration and Medline databases entail two different search processes when conducting research. The Cochrane collaboration is a stand-alone database that is comprised of systematic reviews and meta-analyses conducted by internal researchers. Medline is the National Library of Medicine’s search engine encompassing many different databases, including PubMed.

The three key questions in research are: Are the results valid, what are the results, and will the results help me in caring for my patients (Fineout-Overholt, & Melnyk, 2015). These three questions measure a search results’ validity, reliability, and applicability to practice, respectively. Systematic use of these questions has helped me to evaluate research results from the various databases to determine the quality of material in them.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
