Regardless of what your clinical question is the first pace in evidenced-based decision making is searching the research literature. The past small in number decades have provided an explosion of information in the biomedical sciences. This proliferation of research data has facilitated the proces of evidence-based decision making if it be not that has made the process of finding the evidence more challenging. For example, using the search words "cardiac rehabilitation" in the MEDLINE database bring forwards 144 matches of articles published prior to 1980 and 1338 matches of articles published to date. The meaning of this article is to describe available databases that pertain to cardiopulmonary physical therapy. We will summarize the ease of and access to preferableed databases with information related to cardiopulmonary physical therapy. This article will also use MEDLINE via PubM as an example database to demonstrate for what reason to effectively perform searches.

DATABASES & SEARCH TOOLS

A database is a compilation of information that has been clustered together based on some commonality in topic or prototype of information. For example, AIDSLINE shelters a common topic of clinical aspects of AIDS in a variety of sources including journal articles, parts reports, meeting abstracts/ papers, and audiovisuals. reciprocally AP Photo Archive is a database of throughout a half a million photographs covering diverse topics.

Sometimes information databases are clustered together in a search tool or retrieval regularity Ideally a search tool allows more than the same database to be searched simultaneously. For example, Internet Grateful M is a search tool that has been used to interface with many of the National Library of Medicine's (NLM) information resources. The databases that were included in Internet Grateful M are outlined in Table 1 Internet Grateful M independently searched each of these databases sequentially and not concurrently Internet Grateful M (version 263) is in the proces of being replaced on the new NLM Gateway interface that searches multiple, Webbased NLM information orders This search tool will perform simultaneous searching in multiple databases. Internet Grateful M searches MEDLINE using the retrieval engine of the National Library of Medicine's PubM search tool and this will continue with NLM Gateway. Data conversion is drawed to be complete by September 2001 at which time Internet Grateful M will be completely retired. NLM Gateway Search includes the databases listed in Table 1

Now that we have defined what an information database and search tool are, we will discuss in what manner to find information that assists you in making evidence-based clinical decisions. a certain information databases and search tools are available for unrestricted use. Therefore all you ne is the Web site address or link to the database to start a search. For example, emancipated access to MEDLINE is available end PubMed. Unfortunately many of the information databases that you may want to use have access restricted by means of subscription. Sometimes you may be able to subscribe and pay a single in kind time use fee. The Cochrane Library is an example of a database that is accessible by the agency of subscription only. Table 2 includes descriptions and access information upon databases related to areas of physical therapy practice. Many health science libraries have institutional subscriptions to multiple information databases that require subscriptions. If you have an affiliation with the institution, you can access these databases without charge. Usually you ne to access the database from within the institutional network theory and/or need a password. ofttimes academic institutions extend adjunct or affiliate status to clinical instructors, clinical coordinators of clinical education (CCCE) and visitant lecturers. This status often includes library access and privileges. Alumni are also sometimes granted library privileges at universities. Finding disclosed if you or your facility has potential access to a health science library can be a valuable asset for medical literature searching.

After you have identified the information databases that you want to search, then you ne to decide forward what key words to use in your search. That heartys easy enough, type in a leash of words and out ensues the evidence you need to answer your clinical question! Well if your search issues up with no matches you will probably not be too happy. Perhaps your snare or Boolean terms were not the chiefly appropriate for the search. by conversion if your search comes up with 3000 matches you probably will be quite overwhelmed. In this case you may ne to use a narrower period of time and/or set limits to your search. As you can behold information database searching has a language of its be in possession of Table 3 outlines some of the explanation terms used in MEDLINE/PubMed database searching.

PubM is an easily accessible MEDLINE search tool that is used extensively in the biomedical sciences including physical therapy. PubM was cause to growed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) located at the National Institutes of Health (NIH). Entrez is a search and retrieval method that integrates information from databases at NCBI. Figure 1 illustrates the Entrez databases including PubM PubM provides citations and abstracts of research journal articles. abounding text documents also may be available by the and of links to journals at Web sites of participating publishers. User registration or a subscription fee-simple may be required to access full-text articles in more [i]or[/i] less journals. MEDLINE database searching via PubM will be used as an example to discuss about of the options and [i]modus operandi[/i]s to effectively find information to answer clinical questions.
