Start with one concept at a time. This technique lets you mix and match search sets. When you have multiple concepts it’s easy to end up with nothing. So, start with one concept and add the others one at a time. You might find that you can only use two concepts together out of three. You might need to mix and match them in different combinations.
Combine terms with OR to get more results. When there isn't much on your topic or the MeSH term is new, combine terms with OR to find the most articles. A search in Ovid MEDLINE on electronic patient records - a new MeSH term - might look like:
Electronic Health Records/ or electronic patient records.mp.
Combine terms with AND to get fewer results & to bring topics together. To combine the search on electronic patient records with the topic of medical errors, you need to combine the two searches with an AND. In MEDLINE, it looks like:
1) Electronic Health Records/ or electronic patient records.mp.2) exp Medical Errors/3) 1 and 2
You can also type it out in one line like this: (Electronic Health Records/ OR electronic patient records) AND exp Medical Errors
Spell out terms. You will get better results when you type out abbreviations & acronyms. Keying in electronic health records instead of EHR will generally net you more matching MeSH terms, more keywords found. Ovid MEDLINE does a good job of matching acronyms to MeSH but doesn't always succeed. PubMed doesn't even try. (Check the Details box.) So, type 'em out.
Use available subject terms. In MEDLINE, for example, searching 'computerized decision support' takes you to 'Decision Making, Computer-Assisted' as a MeSH. This usually gets you more results and also allows you to use the Explode feature.
Look for additional terms to search on in titles, abstracts, assigned subject terms, and full text of articles. You might find that there are additional terms that you can search on. Not everyone in a specific specialty or field uses the same terms when writing up articles. Trick is to find the terms that they do use. Once you find the terms, re-do the search. This is another to break up your searches into separate topics. You can then mix and match 'em without having to retype everything.
Check the subject terms used by the database/search engine you are in. Each one has a different focus and therefore, can use a different term for the same idea. You can also use this as a way to find additional terms that you can add into your search.
You can find good articles by looking at References and Cited by.
References are the articles and documents listed in an article's bibliography or reference list. This will take you into the past, to older articles.
You can also search into the future by looking at Citing articles or Cited by links in search engines such as CINAHL, Scopus, or Google Scholar. Say you have an article from 2000 and you want something more current. You can search it by title in Scopus. If the article is found, check to see if there is a number on the far right under the Cited column. Clicking on that number will take you to the more current articles that used the original one in their footnote section.
Use multiple databases/search engines. There will be overlap in what you find, but each will have something unique. The following should be helpful for most if not all searches. All of these are available off of our website either under quick links or All Resources:
Extrapolation is key. Keep in mind that you may have to pull pieces of information from various articles to make your point. You may not – probably won’t – find the perfect article that sums up your position. (If you do find that perfect article, it actually means that you should pick another topic as someone has beaten you to the idea!)
Take notes as you go. It’s really hard to find or document things after the fact. (I’ve found this out the hard way!) So tract where you search, the terms you use, and the citations you find as you go. Paper or online doesn’t matter. Just track it. Also, if an article looks *remotely* useful, make note of it. It’s always easier to cross it off later than try to find it again. (Sometimes you can’t find it again. I’ve learned that the hard way too.)
