Database Searching (NHS)

Transcription

1 Database Searching (NHS) 1. Why use Databases? Databases hold bibliographic information about articles across a wide range of journal titles. You use them to search for articles within a particular subject area, but across a wide range of journal titles. Different databases will often have different interfaces and different options for you to select in order to focus your search; as well as different facilities to help you to manage your searches. NHS Evidence have developed the Healthcare Databases Advanced Search (HDAS) resource to help you to search multiple databases that we subscribe to. 2. What Databases are available? NHS users have access to a number of databases via HDAS. These include: AMED :: BNI :: Cinahl :: Embase :: Healthcare Business Elite :: HMIC :: Medline :: PsychInfo :: Use Databases to find articles 3. Accessing the NHS Healthcare Databases Advanced Search (HDAS) You can access HDAS via the NHS Evidence website at You will need your NHS Athens Username and password. Click on the option for Healthcare Databases Advanced Search Log on with your Athens username and password. You will then be able to select which database you want to search. You ll need your NHS Athens username and password to get access

2 You can select multiple databases, however you will be restricted to a text-only search and the number of limiting options will be reduced. 4. Using the Search Interface The search interface is common for all the databases available. This means that you only have to learn how to use one interface. The interface is very comprehensive and offers a great deal of functionality. This guide will only cover the basics to get you started. Search using Keywords Entering Text Keywords: You can enter free-text keywords into the search box. You can: Combine search terms using AND Combine search terms using OR Use truncation * Use quotes to search for a phrase Group parts of your search using parentheses ( ) Try different search terms to find the most relevant Setting Search Limits If there are too many articles you can use the options on the limits tab to focus your search. Select each limit option and then enter your limits. The number of results returned will be updated. Note that the limits available may vary depending on the database(s) that you have selected to search. Submitting your Search Criteria Search limits help to focus your search When you are happy that your search criteria will return an acceptable number of results you should click Search. Search using MeSH Terms or Mapping to the Thesaurus: You can search using MeSH terms (medical subject headings). MeSH terms are: Applied by qualified information professionals Provide consistent terminology You should use both keyword and thesaurus searching

3 May result in fewer terms required Do not have to be present in the title or abstract To search for a thesaurus term enter a text term in the search box, tick the Map to Thesaurus box and click Search : You will be presented with a number of thesaurus terms to select from (see example above). For the thesaurus term that you want to use: Click the + to view the list of related terms in the thesaurus tree Tick the Select box if you want to use this term Tick the Exploded box to include all the narrower related terms. This is useful to expand your search Tick the Major Descriptor box if you only want articles where this is a major term. This is useful to narrow your search Tick the Subheadings box to get a list of subheadings linked to this term. You can then narrow your search to a specific heading You can select more than one term. If none are returned go back to the search box and try a different text term. Your results will be presented in the Search History section if you want to apply limits to your thesaurus search click the Apply Limits link and select your limits as described above. Viewing Results The results of searches are added to the Search History table. Each search can be: Saved select the search by clicking the tick box next to it; then click the Save selected lines button Deleted either click the X button at the end of the search line or select the search by clicking the tick box next to it; then click the Delete selected button You can hide the search history box by clicking on the Collapse View button
