Search strategies for alternatives are frequently divided into two phases, reduction and refinement, and replacement.
Phase 1: Reduction and Refinement usually consists a generalized database search to retrieve citations relevant to the investigator's field of study. Such searches should provide information on current research, alert the investigator to whether or not they are performing duplicative studies, and possibly provide information on refining experimental techniques. Goals are to minimize the number of animals used and to use techniques and procedures that reduce pain and distress.
Phase 2: Replacement begins once the investigator has a basic understanding of the research, area, including the literature published in the field, the techniques used, and the commonly used species. Goal is to substitute animal models with non-animal techniques or lower organisms whenever possible.
In searching for alternatives, multiple databases should be searched using search terms such as:
animal testing alternatives
animal use alternatives
It is important to remember that although electronic databases are powerful tools, some of the subject databases still do not cover journal articles published before the1960s. Print indexes in relevant areas are still available in the Purdue Libraries if the online version does not cover earlier years.
