IntroductionIn this assignment, I will demonstrate how I searched for evidence using a given clinical question. The first step entailed identifying the key terms in the PICO question and finding alternative words. When performing the search in the two selected databases, I used the main keywords in the PICO question and alternative terms to find relevant resources. Search for evidenceNurses should strive to search for the highest level of evidence to answer clinical questions. This concept is supported by the fact that evidence-based practice (EBP) entails searching for evidence and utilizing that evidence to make clinical decisions [ CITATION Bur11 \l 1033 ]. PICO is an acronym for population, intervention, comparison and outcome and it is used for diagnostic as well as treatment studies [ CITATION Rai13 \l 1033 ]. The key terms for the clinicalquestions are (P) young women, I (green tea), (C) black tea, and (O) prevent cancer. I would use these alternative words, young ladies, tea, malignancy and tumour. The key words in the clinical question and alternative words would be used in combination to ensure relevant sources (peer reviewed journals) are gotten for this study. Moreover, search techniques such as Boolean operators, truncation, wildcard and limiters would be used to broaden and narrow the search as desired. These keywords would help me to gather sufficient records and information for determining whether green tea is better than black tea in preventing cancer.The best two databases that would be used to search for evidence based on the clinical question are CINAHL Complete and PubMed. These two databases have been chosen because ofseveral reasons. CINAHL Complete allows users to get quick full-text access to peer reviewed Student name/student number
journals and evidence-based care sheets. Additionally, CINAHL Complete has vast volumes of literature that are helpful to nurses and allied health professionals. The database offers full text access to about 1,300 journals, indexing for about 5,400 journals. It has searchable cited references for approximately 1,500 journals. Users can have access to approximately 5.5 million records [ CITATION EBS17 \l 1033 ]. The Cumulative Index to Nursing and Allied Health Literature (CINAHL) is also an effective tool for primary studies for qualitative evidence synthesis. On the other hand, PubMed has been chosen because it specifically contains medical literature. Most practitioners use this database for medical literature. PubMed is also desirable because it indexes only peer reviewed biomedical literature. Further, PubMed offers free full-textaccess to some top publications [ CITATION Sha13 \l 1033 ]. Unlike other databases, PubMed offersindexed information that is directly pertinent to physicians such as restricted vocabulary and access to discipline-specific filters. CINAHL Complete and PubMed have various difference based on the number of academic resources, ease of retrieval and limiters, but they would be relevant to the search for evidence based on the identified keywords.In this table, I will demonstrate how I performed a search using CINAHL complete. The table is adapted from [ CITATION Ric161 \l 1033 ].ActionsSearch modeResultsLimiters (or expanders)S1 Young women AND cancerFind all my search terms 29,449Scholarly (Peer Reviewed) Journals 2012 - 2017S2 Black tea AND cancerFind all my search terms2,816Scholarly (Peer Reviewed) Journals Student name/student number
