Define

Terms and ideas from proposed study, possible search terms, possible search questions

Reading through the protocol, make notes of terminology, procedures, drugs, considering what questions need to be asked related to replacement (model choice/necessity), reduction (unnecessary duplication, study design), and refinement (methods/procedures potential pain/distress), and current best practice/SOP/guidelines.

Questions to be searched common to all protocols

Is the proposed research necessary, what has already been done in this area, what models have been used, what best methods/procedures, and
alternative consideration for potential pain and distress

  • List every procedures in the protocol that has the potential to cause pain or distress.
  • Identify other possible terms for each technique that you have identified; determine if a subject heading for each procedure exists in the database that you are using. 
  • Search each of these procedures, considering alternative methods to accomplish the same goal.
  • Begin by searching broadly for each technique. Next, try combining each technique with some of the keywords and subject headings for pain/distress prevention and control, analgesia/anesthesia, and refinement as listed in keywords and in the search examples.

Formulate the questions

for example

What is the effect of [intervention/exposure] on [outcome measures] in [animal species/population] for [disease/health problem]?

How to teach [procedure/technique] to [populaton]?

 

Consider the research-related terms
Scientific, common names of any species
Scientific, common names of any diseases, conditions
Generic name, trade names of any drugs, chemicals
Scientific, common terms for tissues, systems, or cell lines
Treatments, procedures

 

Note keywords and synonyms
It is important to record these keywords at the beginning of your literature search so that you are able to both be consistent across searches and provide the required narrative account of your literature search in your protocol. If you make changes or additions to your list of keywords, include those changes in your records.




3Rs-related keywords
There are many options for keywords in the 3Rs. When choosing keywords, it is important to know if the specific database has a special vocabulary - it may index one keyword but not its synonym. It may also require you to put your keywords in a specific format.  

For example, PubMed's subject headings, MeSH, are different from that used by CAB or AGRICOLA.

USDA's Policy #11: Painful and Distressful Procedures  Defines a painful procedure as "any procedure that would reasonably be expected to cause more than slight or momentary pain or distress in a human being to which that procedure is applied, that is, pain in excess of that caused by injections or other minor procedures."
 
USDA's Policy #12: Consideration of Alternatives to Painful/Distressful Procedures  Details the requirement of considering alternatives to painful and distressful procedures, recommending a database search as the most effective method to determine alternatives.
