Telemedicine & Its Impact on Veterinary Medicine
Telemedicine as a Tool in the Veterinary Practice
Telemedicine is currently a hot topic in the veterinary profession. But what is telemedicine, and what does it mean for veterinary professionals and their clients?
Telemedicine is just another tool that can be useful in daily practice to increase client communication, provide client convenience, promote the client’s bond with the practice, and improve patient care. However, just as an ultrasound machine is not relevant to every case, not every case will be appropriate for telemedicine. Veterinarians will need to use good judgement to determine when telemedicine modalities will help them, their patients, and their clients.
At the AVMA Convention in Indianapolis, the AVMA House of Delegates voted to implement a new policy regarding telemedicine. (See Key Highlights from the AVMA Policy on Telemedicine.) See Definitions for the AVMA definitions of telehealth and telemedicine, which will help provide a framework for telemedicine discussions.1 Simply communicating with a client via email, text, or other electronic means is using telemedicine.1
- Telehealth is the overarching term that encompasses all uses of technology geared to the remote delivery of health information or education. In other words, telehealth could be used to describe everything from websites to activity trackers for pets. If a veterinary team updates clients about their pets’ health by using the phone, emailing, or sending and receiving text messages, images, and videos, they are using telehealth tools.
- Telemedicine is a subcategory of telehealth in which technology is used to exchange medical information about a patient’s clinical health status from one site to another. The most obvious uses for telemedicine are for diagnosing cases and prescribing medications (eg, a client‒veterinarian video call that replaces a physical visit to the practice).
a Definitions adapted from the AVMA Practice Advisory Panel’s final report on telemedicine, published January 2017.
When using telemedicine tools, just as when using any other diagnostic or treatment tool, the veterinarian must have an established veterinarian–client–patient relationship (VCPR). The Federal Drug Administration (FDA), along with most states, has specific laws and regulations regarding the VCPR, and practitioners must know what is applicable in their state. In addition, legal liability and responsibility extend to both the state where the practitioner is located and the state where the patient is located.1 (See Telemedicine: The Scale of Legal Implications.) Outside an existing VCPR, any veterinary advice given via electronic means should be general in nature and not specific to the animal’s medical condition, according to a personal communication with the AVMA Professional Liability Insurance Trust.
Teleconsulting (eg, sending radiographs to be reviewed by a radiologist or ECGs to be reviewed by a cardiologist) is a common component of telemedicine that most practitioners use regularly. Emergency teletriage is another important component of telemedicine. Animal poison control services are a prime example, as are potential heat stroke or drowning cases. Although the AVMA supports emergency teletriage until a veterinarian can see the patient, the organization is opposed to remote consulting offered directly to the public when the intent is to diagnose and/or treat a patient in the absence of a VCPR.1 Telemedicine can also be used to monitor herd health or disease outbreaks (eg, avian influenza at a poultry farm) or in times of a natural or manmade disaster. During a disaster, clients and their animals may not have access to veterinary care because roads are impassable, transportation is shut down, or veterinary care is not available at the evacuation facility. A client and his or her veterinarian can use telemedicine tools to manage basic medical concerns (eg, stress-related diarrhea, treatment of minor wounds) until the client can gain access to veterinary care.
The AVMA is creating a toolkit that practitioners can use to further incorporate telemedicine tools into their existing practices. The toolkit will include potential applications, various service model descriptions, case studies, legal and regulatory considerations, equipment resources, and monetization guidelines (ie, many smartphone apps will allow practitioners to charge for their time and services). Further details will be released when the full toolkit is rolled out at the July 2018 AVMA convention in Denver.
Telemedicine is expected to become increasingly more common in practices,2,3 especially because millennials, who typically prefer electronic communication—particularly text-based—are the largest and fastest growing segment of pet owners.4,5
Various telemedicine platforms (eg, text, email, smartphone apps) can help veterinary professionals better communicate with clients. For example, consider sending postoperative surgery pictures to let a client know her pet came through with flying colors, or send a client a text to let him know his pet’s urinalysis was normal and the previous urinary tract infection has cleared. These modalities can also be used to further build on the education the veterinary team provides in the examination room (eg, a refresher on new puppy housetraining, instructions for performing a glucose curve at home on a newly diagnosed diabetic cat).
Video, another useful aspect of telemedicine, can be pivotal in cases in which determining if the animal is having seizures or syncopal episodes is difficult. In addition, in those common, frustrating intermittent lameness cases, the client can video the pet’s limp and send the video to the veterinarian, who is then able to determine how to localize the problem and where radiographs should be taken to diagnose the cause.
How Communication Pays Off
- Enhancing client communication, whether traditional or electronic, is one of the top changes that would have the most significant positive impact on the practice.
- What’s the financial payoff? Enhanced client communication often results in improved client compliance, leading to a stronger average invoice amount. Just a $10 increase for a veterinarian generating 3000 invoices per year would grow revenue by $30 000.

None of these problems preclude the need for an established VCPR, a physical examination, and potentially other diagnostics, but the tools of telemedicine can help enhance patient care. Many veterinary professionals are already using these tools every day without realizing they are practicing telemedicine.
Key Highlights from the AVMA Policy on Telemedicine
The AVMA Policy on Telemedicine was developed after 2 years of intensive study and input from members and stakeholders. The policy provides a balance between ensuring access to the convenience and benefits afforded by this tool and promoting the responsible provision of high-quality veterinary care. The policy also reinforces that telemedicine should only be conducted within an existing VCPR. The AVMA recognizes that future policies will be evaluated and informed by evidence-based research on the impact of telemedicine with regard to access to care and patient safety.
The AVMA recognizes the need for emergency teletriage services (eg, poison control) but is otherwise opposed to remote consulting offered directly to the public when the intent is to diagnose and/or treat a patient outside an established VCPR. A veterinarian who has an established VCPR, however, has the professional discretion to consult with specialists or other experts, and the consultant should not be required to hold a license in the state where the veterinarian with the VCPR practices or where the patient resides (ie, the veterinarian with the VCPR should be able to have a radiologist in another state read a patient’s radiographs).
Telemedicine guidelines should be harmonized across the nation and strongly enforced to protect patient and public safety. The AVMA supports regulatory efforts to clarify where the actual practice of veterinary medicine occurs when offered through telemedicine modalities, who has regulatory enforcement and disciplinary authority, and what remedies are available in case of patient harm.
Eligibility to provide telemedicine services should be restricted to those people who are legally authorized to practice veterinary medicine in that state, and the credentials of all advice givers, as well as any disclaimers, should be unambiguous and clearly displayed. Clients should be aware of the advice giver’s identity, location, licensure status, and potential privacy and security issues with electronic communications.
Finally, the AVMA policy states that the legal accountability, liability, and responsibility of the practicing veterinarian should be in both the state where the patient is located and the state where the veterinarian is located.
1Be familiar with the definition of VCPR in the state where you practice.
2Document any telemedicine services in the medical record in the same manner as traditional professional services.
3Do not be afraid to add telemedicine services to your practice to improve patient care and bond clients to your practice.
4Be familiar with your state’s legal telemedicine requirements.
The Scale of Legal Implications
Telemedicine is changing the world of veterinary medicine, and veterinary teams need to know the legal ins and outs.
The terms telehealth and telemedicine are sometimes used interchangeably, but they have different meanings. (See Definitions and Key Highlights from the AVMA Policy on Telemedicine.)
When clients have the potential to access veterinary healthcare over the internet or via an app, geographic boundaries could become irrelevant. Veterinary clients, the consumers of veterinary services, want access to better, less expensive, and more convenient solutions to their pets’ health problems.
Technologies ranging from apps that enable video calling to smart litter boxes that analyze urine to at-home chemistry analyzers all have the potential to change the way veterinary practices deliver services and communicate with clients. Increased access to an individual patient’s data has the potential to increase client portability and access to a wide range of service providers. Telemedicine is frequently discussed because it has the potential to disrupt the veterinary profession.
Standing somewhat in the way of this disruption are laws and regulations. Most states require that the practice of veterinary medicine start only after formation of the veterinarian–client–patient relationship (VCPR). Traditionally, this is when the veterinarian meets with the client and examines the patient.
Several states (eg, Texas,1 Tennessee,2 Utah,3 Georgia,4 Illinois,5 Iowa,6 Mississippi,7 Washington8) have laws that prohibit forming the VCPR by electronic or telephonic means. Some states insert the word “physical” in front of “examination,” which could easily be interpreted to mean a face-to-face meeting. Other states (eg, Delaware, Washington DC, Alaska) have no VCPR requirement before a patient is diagnosed or treated.
Federal laws generally leave regulation regarding the practice of veterinary medicine to the states, but the US Food and Drug Administration controls the medications veterinarians use. Federal regulations limit a veterinarian’s ability to prescribe a drug in an extra-label manner without first establishing a VCPR. Although more drugs are becoming available with more labels, practicing veterinary medicine without reaching for extra-label drugs is still difficult. Even in states without a VCPR requirement, telemedicine providers cannot legally prescribe extra-label drugs.
Federal regulations also prevent telemedicine providers from writing veterinary feed directives for food animals, including backyard poultry and potbellied pigs kept as pets.
State veterinary boards are responsible for ensuring that veterinarians comply with the practice act. In most states, a veterinary professional who practices veterinary medicine without a valid VCPR is subject to state board action.
Board actions have led to at least one lawsuit concerning telemedicine in veterinary medicine.9 The author expects state legislatures, state boards, and regulatory agencies to provide more detail in the future. Regardless, here are the author’s recommended boundaries and best practices.
- Be licensed in the state where the client and pet live
- Know the difference between interactions in which a VCPR does and does not exist
- Remember that the same Standard of Care that applies to face-to-face medicine applies to telemedicine. Providing low-level care is not an option just because the veterinarian and pet are not in the same room.
- The same record-keeping requirements apply to telemedicine as to face-to-face practice.
The VCPR Requirement
The VCPR requirement includes 4 subcategories. (See The Veterinarian–Client–Patient Relationship Requirement.) Any potential telemedicine offerings in the practice should be separated into these categories.
Telehealth already is changing veterinary medicine, and veterinary professionals must remain aware of their clients’ needs as well as the laws and regulations that govern the profession. There is no doubt the laws will change, and veterinarians must help facilitate that change as more details and guidance emerge in telehealth and telemedicine.
The Veterinarian–Client–Patient Relationship Requirement
The requirement includes 4 subcategories.
1 Telemedicine for New Clients
Starting a VCPR through electronic communications (ie, displacing the physical examination in lieu of electronic communication) is the most contentious issue surrounding telemedicine. Before attempting this form of telemedicine, check your state’s practice act and board regulations for language barring a VCPR from being formed by “electronic means” or language that requires a “physical” examination to form the VCPR.
2 Telemedicine for Existing Clients
After the VCPR is established, veterinary practices can communicate with their clients on a regular basis. The time, duration, and scope of the conditions that the continuing VCPR covers have not been fully decided in most states; however, in all cases, knowing what the state practice act allows is important. For example, in California, a new VCPR must be established for each condition (ie, a veterinarian cannot see an animal for a femur fracture and then use telehealth tools to diagnose and treat the patient’s otitis externa), and the veterinarian must examine a patient at least once a year in order to write prescriptions for that patient.10
3 Telemedicine Between Veterinarians
The consultant relationship has been long used in veterinary medicine for advice on specific cases. The veterinarian of the VCPR often transmits images or information (eg, radiographs) and receives advice on interpretation, diagnosis, and treatment. Some grey areas remain, including whether or not the consultant can communicate directly with the client and possible liability to the consultant veterinarian.
Various poison control hotlines have been doing teletriage for years. In the context of private practice, the client receives general advice, applies the advice to his or her situation, and makes the decision whether to rush the pet to the emergency room or wait until the practice is open. Teletriage has been generally accepted by state boards, but there is a fine line when it becomes the practice of veterinary medicine, and the wording of the recommendation sentence becomes very important. General advice concerning the situation is permitted, but rendering advice to diagnose or treat becomes the practice of veterinary medicine. Some new services provide teletriage for practices, and these grey areas will need definition.
Monitoring Advances in Technology
As in-house technology increases our ability to care for veterinary patients, so does the use of remote technology-based resources. Never before have so many resources been available to improve the health and care of all animals, even in the far corners of the world.
Traditionally, telemedicine consultations have been helpful, but the amount of information specialists can access is limited because they are not in physical contact with the patient. However, advances in technology mean advances in telemedicine in general and anesthesiology in particular.
Currently, anesthesia telemedicine services include email or telephone consultations before anesthetizing patients with increased anesthetic risk or after adverse outcomes. Picture messages or short video clips can be transmitted during a case when help is needed to interpret physiologic waveforms, provided the anesthesiologist is available at that moment to read them.
Advances in telemedicine currently enable remote monitoring of patient vital signs via Bluetooth, allowing veterinary team members and remote specialists to continuously monitor the vital signs of patients under anesthesia or in recovery. Cloud-based applications will be available in 2018. Physiologic data sent over the cloud can include pulse, respiratory rate, temperature, pulse oximetry, blood pressure, and glucose levels.1
Anesthesia services that telemedicine will bring also likely include:
- Real-time remote monitoring of anesthetized patients in 2018
- Continuous monitoring of patient status, which enables earlier recognition of downward physiologic trends and can facilitate earlier interventions and potentially decrease patient morbidity and mortality
- Continued observation of patients, allowing them to return home earlier after sickness or surgery instead of remaining in the practice
Through telemedicine, the ability to easily transmit real-time physiologic data is an exciting new opportunity to better care for patients under anesthesia and those recovering at home. This capability will be available in 2018 and should help strengthen all team member–client–patient relationships.

Critical Help for Those Working Alone
As a young clinician fresh out of my internship, I worked for an overnight emergency practice. My internship had (mostly) prepared me for emergency work, but still, some horrible cases that were crashing and burning arrived in the middle of the night, leaving me struggling alone to decide what I should do.
Being alone, without a team member or someone more experienced to consult, was an isolated and scary feeling. Those early experiences inspired Critical Consults, the company I started in 2014 to help meet the needs of veterinarians faced with difficult emergency and critical care cases.
Feeling alone and not knowing what to do next is stressful, whether during a busy day or in the middle of the night. Hearing the relief in another team member’s voice as we create a treatment plan together is one reason telemedicine is so important.
How We Use Telemedicine
Here is how Critical Consults provides support.
- Veterinarians call our board-certified criticalists who are available at all hours, every day of the year. Six criticalists provide consultation on small animal emergency and critical care cases, with one consultant on call at any one time. All the consultants, who have academic backgrounds and private practice experience, are chosen for their ability to provide high-level service.
- Calls ring straight through to an experienced specialist.
- A board-certified anesthesiologist provides consultations to specialty practices and general practitioners for difficult cases. We also help practices set up anesthetic protocols.
- We help direct the diagnostics and treatments that are most essential when the clock is ticking, allowing the consulting veterinarian to concentrate on the most important aspects of the case (eg, providing insight into management of unstable respiratory cases, helping the veterinarian in charge treat a case of shock and hypotension).
- We have removed any barriers that take up precious time—no account set-up is required and no credit card is needed. Case information and the practice address are recorded during the consultation, and the practice is billed directly each month.
- To ensure greater service, we work with a group of small, independently owned telemedicine consulting companies that provide a variety of specialty services (ie, radiology, neurology, oncology) and serve as a virtual referral practice.
Our company’s goal is to provide a lifeline to those in need. Our services allow veterinarians to be more efficient when minutes matter, improve the quality of care, and, most importantly, lower the team’s stress level. If we can help point the team in the right direction, patient outcomes improve and treatment becomes more efficient and effective. We always hope our colleagues do not need us, but if they do, they know they are not alone.
The View Ahead
Teleradiology sounds simple: Send radiographs to the radiologist and receive a report that explains exactly what the problem is and what to do next. However, getting a clinically relevant report requires more planning than simply sending a brief request.
Radiologists can interpret radiographs and other imaging modalities (eg, ultrasonography, CT, MRI, nuclear scintigraphy). The radiologist’s comfort level with different species (eg, exotics) may vary, so be sure he or she is confident with the type of case to be submitted.
Some radiologists offer services in CE (eg, improving technique at practices, mobile ultrasonography). Teleradiology companies vary from an individual radiologist to large groups with multiple radiologists whose services are available all hours.
When sending radiographs to the radiologist, these tips can help ensure he or she is able to provide the most information possible.
- To make the most of the consult, images with ideal positioning (ie, straight, no legs superimposed over thorax or abdomen), collimated to the area of interest only, and with appropriate exposure are necessary.
- Rotated, under- or overexposed, uncollimated, or incomplete images will limit the amount of information that can be reported.
- Orthogonal views are ideal.
- If ideal views are not possible in the awake patient, sedation or anesthesia may be necessary.
- A complete study should include the full series of images (eg, all times and orthoganal views on an upper GI series).
History & Examination Findings
To be most helpful, provide a concise but thorough history that summarizes the client complaint, examination findings, and any pertinent medical history or prior treatment, which allows the radiologist to rank differential diagnoses or suggest further studies. For example, instead of recording lameness, consider non–weight-bearing lameness of the left thoracic limb, localized to the elbow, 2-week duration.
The majority of states require the telemedicine specialist to be licensed only in his or her state of residence, as the referring veterinarian holds the primary VCPR. (See The Veterinarian–Client–Patient Relationship Requirement.)
At this time, 3 states require separate licensing (ie, Connecticut, Michigan, New York), where the telemedicine specialist must be separately licensed and have completed the CE these states require. This is particularly important in New York because not all CE is approved by the New York board. (See The Scale of Legal Implications and Key Highlights from the AVMA Policy on Telemedicine.)
Working with the chosen radiologist by providing ideal background and images will provide the best report and experience—for the clinician, the radiologist, and the client.
Getting to the Root of the Problem
Intraoral radiographs are essential for planning and assessing outcomes of dental treatment. Use of dental films in veterinary medicine was first documented in 1958,1 and digital technology has made its use easier than ever.
Studies of the diagnostic value of full-mouth dental radiographs in dogs and cats found that radiographs of teeth without clinical lesions yielded clinically important findings in 41.7% of cats and 27.8% of dogs, whereas radiographs of teeth with clinically visible lesions yielded essential information in 22.6% of dogs and 32.2% of cats.2,3
The diagnostic yield of full-mouth radiography is high in new canine and feline patients referred for dental treatment,2,3 and routine use of full-mouth radiography is justified.
With the above data in mind, more practices are making intraoral dental radiography part of their dental procedures. Like most new diagnostic tools, there is a learning curve in determining normal from abnormal, which is where dental teleradiology comes into play.
Like most dentists who provide dental teleradiology services, NorthStar VETS offers stat and non-stat interpretations of dental radiographs. The stat interpretation, when available, allows patients still under anesthesia to benefit not only from a boarded diplomate’s diagnostic interpretation but also from his or her treatment recommendations. It is like having a veterinary dentist looking over your shoulder.
Dental teleradiology is likely to become increasingly important as the number of veterinary practices that adopt digital dental radiography as an essential diagnostic tool continues to grow.
