Use of Pentobarbital Among Veterinarians Survey

Contract No.: 75F40120P00437

OMB Control No. 0910-0697

Expiration Date: 12/31/2023

Survey to Determine Euthanasia Practices and Use of Pentobarbital Among Veterinarians Practicing in the United States

A quantitative survey of the American Veterinary Medical Association (AVMA) members will be conducted to gauge practitioner understanding of euthanasia methods and gathering information for decision-making considerations for choice of euthanasia method by species, and recommendations made (or not) for disposal of the resulting carcass.

According to the Paperwork Reduction Act of 1995, an agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a valid OMB control number. The valid OMB control number for this information collection is 0910-0697 and the expiration date is 12/31/2023. The time required to complete this information collection is estimated to average 10 minutes, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

Send comments regarding this burden estimate or any other aspects of this collection of information, including suggestions for reducing burden, to [email protected].

Web Greeting

(Web greeting will be on the opening survey page with the title of the survey and the AVMA’s logo)

Thank you for participating in this AVMA survey. Your feedback is important to us and will help us determine additional needs for information and options around euthanasia and carcass disposal that we hope will assist you as you practice.

This survey is being conducted by the AVMA in collaboration with the U.S. Food and Drug Administration’s Center for Veterinary Medicine (FDA CVM). Individual responses will be kept secure to the extent permitted by law, and only group statistics are compiled and included in reports. Your responses to demographic questions may be used to update your profile in the AVMA’s database.

Should you have questions, please contact the AVMA by emailing Laura Pikel at [email protected].
