The moment medications are utilized well, they have the potential to alleviate symptoms which can compromise the physiological and physical health of an individual. Sometimes medications are not utilized appropriately leading to complications. Osteoarthritis is a conditions which affect joints and it forms part of painful experiences among old women. (Hill, et al., 2015). However, fish oil has omega 3 supplements which studies have shown to ease osteoarthritis.  Even though its effectiveness is still under debate most people who have used fish oil have recorded some great improvements (Chen, et al., 2016).

The study will be based on the table of Richardson-Tench et al. (2016) and different parameters will be used to come up with search criteria. Two types of search databases will be used. These are EMBASE and Medline. Their effectiveness will be outlined in regards to the clinical scenario of Peggy who is suffering from osteoarthritis. In addition, the clinical question which will be handled is if fish oil an effective treatment option in older women with osteoarthritis

 The two search databases are Medline and EMBASE


 This is one of the best search databases which offer the best outcome. It is a national library of medicine which has a wide coverage since 1946. It has got over 22 million records from 5600 of which majorly comes from the United States journals. It covers medical and biomedical sciences thus providing a quick search for information related to fish oil.  It has high-quality scientific content which is fed based on the guidelines outlined in NLM fact sheet (Ji & Yen, 2015). In addition, this particular database is directly searchable via NLM as one of the subsets of PubMed. It is very unique from the other databases because it has the added value of utilizing the NLM controlled vocabulary for such as medical subject headings. It is available through subscription of a number of interfaces


 It has a wide coverage back to 1947 and selectively to 1902. This particular database contains more than twenty-nine million records from more than 8500 journals which are gathered from more than 90 countries in the world. It encompasses all Medline and other two thousand extra titles which also include more than 260000 conference contracts (Qi et al., 2013). The database covers journals with subjects in such as medicine, pharmacy, and drug.

 It is advanced search with guided mapping of main words to Emtree. It entails basic natural language search synonyms and relevance ranking. The database has got extensive limiting options which involve types of EBM, drug administration routes, and clinical trials. It has other features such as emails alerts, RSS feeds and save searches. However, it is very possible for one to export citations to Endnote. One is able to pick the recent articles and even the conference papers with extensive search limitation options.


The outcome indicated that there are lots of literature which can be found to support the idea of using fish oil in relieving osteoarthritis among older women (Hamlin et al., 2016). In regards to PICO, the search articles had terms such as pain, ALA, EPA/DHA Osteoarthritis, omega 3 and NSAID. The database had limited options and this offered refined search criteria for the information. Phrases and connectors were used as search modes and it assisted in getting information much quicker (DiCenso et al., 2014)


  The use of fish oil is a fundamental approach by Peggy to solve her issue on osteoarthritis. Different databases have a different outcome but ultimately, the one with the reliable outcome is the most preferred one. In regards to the used databases, it is important to note that they offered a variety of results which were reliable and come up with much evidence that Peggy was on the right intervention strategy.

However, Medline and Embase databases had distinctive features which excluded them from the other search data bases. For instance, Medline very unique from the other databases because it has the added value of utilizing the NLM controlled vocabulary for such as medical subject headings. It is available through subscription of a number of interfaces. Embase, on the other hand, encompasses all Medline and other covers journals with subjects in such as medicine, pharmacy and drug.
