According to the Animal Welfare Act regulations, "the ACUC shall determine that the principal investigator has considered alternatives to procedures that may cause more than slight pain or distress to the animals, and has provided a written narrative of the methods and sources used to determine that alternatives were not available." The ACUC is also responsible for ensuring that the proposed research does not unnecessarily duplicate other research. To assist the ACUC with this task, the PI is required to conduct a literature search when proposing to utilize regulated species in studies that propose procedures that may cause more than momentary pain or distress to animals. The PI is required to provide the ACUC with the following information under Section G of the NCI Animal Study Proposal form for these studies: the name of minimum two databases used to search for alternatives, the date of your search, the period covered, the keywords that were used, and a brief narrative of the results.
