BRINGING THE EVIDENCE UP TO DATE
One of the criteria for using a particular study in evidence-based practice it its currency. As more studies are done, more information comes forward on a particular intervention. This is particularly important in the instance of therapy where harms often are discovered in much later research. Although secondary and tertiary resources make every effort to have the most complete up-to-date information, it is your responsibility to explore all avenues.
To bring information from a secondary or tertiary resource forward:
1. Locate the record for the original reference in PubMed. ACP Journal Club and Clinical Evidence provide direct links to the PubMed record. In other instances, you will need to search for the original record (see the section on Searching PubMed ).
2. Click on the link labeled "Related Articles". This runs the original article through an algorithm that finds articles of a similar nature. Articles are listed by relevance with the original article appearing first.
3. To find the most recent articles on this topic, click on the box labeled "Sort" and select "Pub Date" (Publication Date). Then click on the grey button labeled "Display". This will re-sort your results.
Note: Not all articles retrieved this way will fit the rigorous criteria required for evidence-based practice. The most you can say is that you know what a particular valid study reported and subsequent research/opinion either bears it out or contradicts it.
