Citations Database Search Help

The citations database is a standalone repository of hundreds of references to published text regarding the Patient Centered Medical Home. This collection can be searched by keyword or phrase or by using the metadata assigned to each citation.

Search by keyword or phrase

The keyword search allows the user to search through the collection by user-selected key words and phrases. To begin, enter the search term or phrase in the text box and select “enter” or the search button.

  • The search is case insensitive. A search for “medicaid” will return the same results as “Medicaid.”
  • The search will look for an exact match of the text entered, so enter only the minimum text required.
  • Do not use punctuation or special characters in your search; results will not be returned unless these characters are also in the title, abstract, or description.

Search by Subject

Each citation has been tagged with a subject tag. These terms are used to describe the main content of the resource. Each citation may have more than one subject tag. When using the subject filter, please note that selecting more than one tag will provide results that contain each of the subjects mentioned. For example, if you select “Outcomes” and “Policy Issues,” the result will be those citations that address both “Outcomes” and “Policy Issues.” An article that addresses “Policy Issues” will be excluded from the result set. Similarly, a citation that has been tagged as addressing “Outcomes” that has not also been determined to cover “Policy Issues” as a central subject will not appear in the search results.

Search by Reference Type

Reference type refers to the origin of the citation and can be used to filter results based on the type of publication the citation refers to. As with the subject filters, you can select multiple reference types to narrow your search. When using this filter, the selection of multiple values (such as book, journal, or presentation) will provide results that match all of the criteria selected.

Search by Special Population

Special Population allows you to filter your results based on the population addressed by the research, policy, or article. Not every citation has a special population identified. If you select more than one population filter, for example, “Children” and “Multiple Chronic Conditions,” your result set will include only those citations that have designated both “Children” and “Multiple Chronic Conditions” as relevant special populations. Citations with no populations designated or with slightly different parameters (“Multiple Chronic Conditions” and “Children with Special Needs”) will not be returned as part of the result set.

Search by Article Type

Articles may be designated as one or more type. Any values selected in this category will be grouped together and the search results will display only citations that have each of the values selected. For example, selecting “Key/ Foundational Articles” and “Outcomes” will display only those “Outcomes” citations that are also considered “key” or “foundational.”

Learn more about the values in each of the categories.

Note: Selecting multiple values across each filter affects the search results in the same way as selecting multiple values within a category. For example, entering the term “pediatrics” in the text box, “Outcomes” as a subject, “Children” as a Special Population from a Book (Reference Type) that is considered “Foundational” (Article Type) would provide only results that meet all of the criteria specified.

Unexpected Results?

You may query the collection and not receive the results you are expecting. If you have received too many results, you can filter your search by selecting additional values under one or more of the categories.

If you received very few or no results, you may have designated too many filters or used special characters or punctuation in the text box. There are several ways to extend your search and broaden your result set:

  • Clear all the filters and use only the text box
  • Select the primary filter (such as Subject) and select one value. At the top of the result page, you will see the number of items in the collection that match that value. You can then browse through the results. If you find an article that meets your criteria, look at the citation to find out what other terms may be applicable.
  • In the text box, shorten the terms you are using to capture any variations on the root search term. For example “Pediatricians” will pick up only those citations with “Pediatricians” in the title, abstract, or description. “Pedia” will pick up not only Pediatricans, but also Pediatrician, Pediatric, and Pediatrics.
