Evidence-based practice = best available evidence + expert clinical judgment + patient & family values/preferences.
When clinicians diagnose & treat based on outdated or inadequate knowledge, then outcomes are at best uncertain. The internet itself is a poor information source; & colleagues may be no more up-to-date that you.
Good sources are the world-wide Cochrane Collaboration and the specific evidence-based practice journals that are beginning to grow–these take best information from the research report all the way through clinical recommendations. For research reports per se, PubMed is a comprehensive, U.S. tax-supported database; & there when you find information that fits using your key search terms, you can also look for related articles & get full-text through interlibrary loan or online. Another strategy is take the article that fits your clinical issue to your librarian, and ask for help in finding more research on the identical clinical issue.
While no one can read everything in the literature, everyone can read something. You can do a focused review on any particular problem.
Critical thinking: Is there a clinical issue that you think could use a better solution? Plug related words into PubMed & see what you can learn.
