Ovid is a popular method of searching MEDLINE, the largest biomedical information database in the world. MEDLINE is maintained by the National Library of Medicine, and contains citations dating back to 1946.
You can access Ovid MEDLINE from the Library’s homepage. You may be asked to login via a proxy account login and password. This can be either your Rush Network ID, Epic ID, or a specific proxy login and password. The link to Ovid MEDLINE is in the Quick Links column on the Library’s home page.
Once you click on Ovid MEDLINE from the Library's home page, you are brought to a screen with two options.
The first option searches all of MEDLINE, from 1946 to the present. It includes the Daily Update and articles that have been published only electronically.
The second option searches all the journals published by Ovid. It does not search journals from other publishers. Not all of these journals are included in MEDLINE, so a search in All Ovid Journals might return new and different results.
As with any database, you will have access to the full text of the items to which Rush subscribes or owns. Those without subscription status will still offer basic information (abstract, table of contents, etc) so you can decide if you want that item. If so, you will be brought to a link for I-Share or ILLiad, our interlibrary loan options.
The search box below is the starting point for all Ovid MEDLINE database searches. If you are searching MEDLINE only (not Ovid Journals), you will have the option to use subject headings. Similar to MeSH searches in PubMed, a"Map term to Subject Headings" search brings you to a screen where you can further refine your search. Ovid will then search for items that have been specifically identified as having your selected subject heading(s) as the main topic. View the "Subject Headings, Explode, and Focus" page of this guide for more information on subject headings in Ovid MEDLINE.
Ovid MEDLINE works most effectively if you search for one subject at a time, then combine the searches.
In this case, there are 88 items that pertain to both zika and malaria.
There are two ways to limit (or refine) your search in Ovid. The first is to embed the limits into your initial search by choosing a criteria from the blue area below the search box. These limiters can be used after the initial search as well, as shown below. The second set of filters is in the grey box on the left side of the screen.
1. Perform your search in the Ovid MEDLINE database.
2. Select the items to send to RefWorks.
3. Click the Export button near the top of the Results Display.
4. Select RefWorks from the Export To menu.
5. Select the Complete Reference button from the Select Fields to Display section.
6. Click the Export Citation(s) button.
7. In RefWorks click the View Last Imported Folder button.
Ovid MEDLINE uses a system called mapping to suggest the most relevant subject headings to the words typed into the box. Your search does not automatically default to searching by subject term, and is not an option when searching Ovid Journals.
Similar to MeSH in PubMed, Ovid's Subject Headings are a way to fine-tune your results. For example, a general search on the word "culture" has the following results:
If you search using the "Map to Subject Headings" option, you might see something that looks like this.
If your search did not map to a desirable subject heading, select the box "Search as Keyword."
If you select more than one term, you can combine them using a boolean operator (AND or OR). Remember, if you want articles about one concept OR another, choose OR.
For example, a search on the word Diabetes using "Map to Subject Headings" gave these options:
If your topic is Gestational Diabetes, using Subject Headings will save a lot of time by eliminating quite a few other areas.
Clicking on the box in front of Diabetes, Gestational brings you to a page with subheadings. This allows you to refine your search even further. If you want all information about Gestational Diabetes, click the Include All Subheadings box. That will return 7527 results.
Choosing Explode (as shown in the image slightly farther up the page) brings you to the same screen as directly above, except now there are 9017 results. This is because Explode returns articles that pertain to Gestational Diabetes but do not have it as a main topic.
Choosing Focus (as shown in the image slightly farther up the page) brings you to the same screen as directly above, except now there are 6190 results. This is because Focus returns only those articles that have Gestational Diabetes as a main topic.
