Evidence-based veterinary medicine is the use of best relevant evidence in conjunction with clinical expertise to make the best possible decision about a veterinary patient. The circumstances of each patient, and the circumstances and values of the owner/carer, must also be considered when making an evidence-based decision.

The basis of EVM is good clinicians using good science to make good decisions about their patients to benefit their health and welfare. To be able to do this the veterinary profession needs high quality, relevant science made readily available to them in clinical practice.
There are five steps to Evidence-based Veterinary Medicine, the "Five As":
1. Ask - This step is about identifying the right questions the veterinary surgeons need answers to.
