You can avoid re-inventing the wheel by checking in with top notch experts who have already examined the practice problem that you face.

In other words, it’s time to head to the library. After all that’s what the library is: the experiences and research written down by experts, who have spent a lot of time thinking about the same problem that you are facing. Really it’s pretty amazing that we have access to health professionals all over the world who are eager to help you avoid re-inventing the wheel.

The best experts in the field are talking directly to you through their publications!

Of course it’s important to ask your colleagues in your own and other institutions about their ideas on the problem, but that’s not enough. You will be limited by what they happen to know; or worse you will be limited by what they don’t happen to know! Nurses on your floor can provide practical, site-specific insights, but it’s easy to see why you would want to add newest information from the top experts. That is BEST evidence.

Remember: EBP = Best evidence + Clinical judgment + Patient/family preferences/values

HOW do you find the experts in the library?

1. The first step is to identify KEY WORDS from your PICO.
2. Use single words or put phrases in parenthesis in your list of words (e.g., “postoperative ileus”). A librarian can help with key words, too.
3. Google the site PubMed (PubMed is a complete database of healthcare publications)
4. In the search box at the top of the PubMed page, type in your key words
5. You will get a list of articles on your topic (and some related articles on the right side)
6. Click on the box beside the ones that you want & email that list to your facility librarian with a request to pull the complete articles for you! (Of course if you are a student with some direct access to full-text articles in a school library, then it may be quicker to get them on your own. It’s up to you, but part of your “village that it takes” might be the librarian.) [See “Take five!” if you want more on to why PubMed beats Google Scholar.]

EXAMPLE: Let’s get specific….

• Take this problem that we have discussed before:
  • P = Postoperative patients with ileus (Population or Problem)
  • I = Gum chewing postop (Intervention to try out)
  • C = NPO with gradual diet progression when bowel sounds start returning (Comparison intervention)
  • O = Reduce time of postop ileus with sooner return to nutritious eating (Outcome that you want)
• What are some key words from the above PICO stated problem? “Postoperative ileus” adults “gum chewing”
• Go ahead. Pull up PubMed. Paste in the key words You should get 11 articles about gum chewing & postoperative ileus. Check the boxes of the ones you want, then…
• Click on the “SEND TO” link near the upper right corner of the screen and email the list to the librarian with a request for full-text of the articles. (You can send to yourself, too)
• Congratulate yourself on an EBP literature search well-started!

CRITICAL THINKING: Why wouldn’t you simply use google.com to find expert opinions?  [If you want more “data”  related to this question.  Check out“Take five!”]
