Notifying investigators of IACUC protocol review outcomes in writing is:

Notifying investigators of IACUC protocol review outcomes in writing is required by the USDA Animal Welfare Act Regulations and PHS Policy. This requirement stems from the need to ensure transparency and communication regarding the status of research protocols that involve animal subjects. By providing written notification, IACUCs fulfill their obligation to convey important decisions, including approvals, modifications, or disapprovals of research protocols.

This practice not only reinforces the commitment to ethical research but also supports the adherence to proper standards and regulations governing animal research. Written notifications serve as an official record, which is crucial for both compliance purposes and for the investigators to understand any necessary changes to their protocols or to seek clarification regarding the review process. Thus, adherence to these regulations is vital for maintaining the integrity of the research process and the ethical treatment of animals in research settings.
