Veterinary medicine is the branch of medicine that deals with the prevention, diagnosis and treatment of disease, disorder and injury in non-human animals. The scope of veterinary medicine is wide, covering all animal species, both domesticated and wild, with a wide range of conditions which can affect different species.
Veterinary medicine is widely practiced, both with and without professional supervision. Professional care is most often led by a veterinary physician (also known as a vet, veterinary surgeon or veterinarian), but also by paraveterinary workers such as veterinary nurses or technicians. This can be augmented by other paraprofessionals with specific specialisms such as animal physiotherapy or dentistry, and species relevant roles such as farriers.
Veterinary science helps human health through the monitoring and control of zoonotic disease (infectious disease transmitted from non-human animals to humans), food safety, and indirectly through human applications from basic medical research. They also help to maintain food supply through livestock health monitoring and treatment, and mental health by keeping pets healthy and long living. Veterinary scientists often collaborate with epidemiologists, and other health or natural scientists depending on type of work. Ethically, veterinarians are usually obliged to look after animal welfare.
Veterinary care and management is usually led by a veterinary physician (usually called a vet, veterinary surgeon or veterinarian). This role is the equivalent of a doctor in human medicine, and usually involves post-graduate study and qualification.
In many countries, the local nomenclature for a vet is a protected term, meaning that people without the prerequisite qualifications and/or registration are not able to use the title, and in many cases, the activities that may be undertaken by a vet (such as animal treatment or surgery) are restricted only to those people who are registered as vet. For instance, in the United Kingdom, as in other jurisdictions, animal treatment may only be performed by registered vets (with a few designated exceptions, such as paraveterinary workers), and it is illegal for any person who is not registered to call themselves a vet or perform any treatment.
Most vets work in clinical settings, treating animals directly. These vets may be involved in a general practice, treating animals of all types; may be specialized in a specific group of animals such as companion animals, livestock, laboratory animals, zoo animals or horses; or may specialize in a narrow medical discipline such as surgery, dermatology, laboratory animal medicine, or internal medicine.
As with healthcare professionals, vets face ethical decisions about the care of their patients. Current debates within the profession include the ethics of purely cosmetic procedures on animals, such as declawing of cats, docking of tails, cropping of ears and debarking on dogs.
Paraveterinary workers, including veterinary nurses, technicians and assistants, either assist vets in their work, or may work within their own scope of practice, depending on skills and qualifications, including in some cases, performing minor surgery.
The role of paraveterinary workers is less homogeneous globally than that of a vet, and qualification levels, and the associated skill mix, vary widely.
A number of professions exist within the scope of veterinary medicine, but which may not necessarily be performed by vets or veterinary nurses. This includes those performing roles which are also found in human medicine, such as practitioners dealing with musculoskeletal disorders, including osteopaths, chiropractors and physiotherapists.
There are also roles which are specific to animals, but which have parallels in human society, such as animal grooming and animal massage.
Some roles are specific to a species or group of animals, such as farriers, who are involved in the shoeing of horses, and in many cases have a major role to play in ensuring the medical fitness of the horse.
Veterinary research includes research on prevention, control, diagnosis, and treatment of diseases of animals and on the basic biology, welfare, and care of animals. Veterinary research transcends species boundaries and includes the study of spontaneously occurring and experimentally induced models of both human and animal disease and research at human-animal interfaces, such as food safety, wildlife and ecosystem health, zoonotic diseases, and public policy.
As in medicine, randomized controlled trials are fundamental also in veterinary medicine to establish the effectiveness of a treatment. However, clinical veterinary research is far behind human medical research, with fewer randomized controlled trials, that have a lower quality and that are mostly focused on research animals.Possible improvement consists in creation of network for inclusion of private veterinary practices in randomized controlled trials.Source : Wikipedia
