Telemedicine is a term that covers the use of technology to deliver clinical care at a distance. It ensures that a person receives healthcare when needed, especially for those with limited access to care.
Telemedicine uses electronic and telecommunication technology to provide an exchange of medical information, despite a person and their doctor not being in the same room.
It can be as simple as text messaging medical care to as advanced as remotely controlled surgery.

Experts also telemedicine used differently in various fields of medicine, such as:
- Telestroke: Experts use telemedicine in emergency departments for neurologists to communicate remotely with emergency doctors, reducing the need for in-house neurologists. This helps deal with the shortage of neurologists in many hospitals.
- Teleradiology: Practitioners send images and reports from in-person or telemedicine exams to a remote radiologist, who then sends their report to the physician or another healthcare professional.
- Telepsychiatry: Direct interaction between a person and a psychiatrist through telephone or video conferencing.
Telemedicine has several benefits for the people and the medical professionals involved.
Comfort and convenience

A 2020 review found that there was a reduction in health costs by 56% and travel costs by 94% when doctors used telemedicine in the following settings:
- intensive care unit (ICU) rooms
Telemedicine allows family members and caregivers to join in the consultation, ask questions, and provide information to contribute to their family member’s care.
Prevention of chronic diseases
A 2021 review found that telemedicine helps provide timely delivery of preventive care to people with cardiovascular diseases. This helps prevent acute events and the progression of these diseases.
Controls the transmission of illnesses
Scheduling appointments and creating more efficient clinic workflows lessen people’s exposure to others who may be ill. It also helps prevent and
Telemedicine helps healthcare professionals like occupational and physical therapists observe a person in their natural environment. This allows them to perform more thorough evaluations of the person’s abilities to move around and interact with their environment.
Some of the common disadvantages of telemedicine
- technological glitches when using devices
- inability to physically examine people
- lack of patient-doctor rapport and trust
- lack of access to the necessary infrastructure, such as high-speed internet
- diagnosis hindrance due to the poor quality camera, images, or lighting
- challenges in ensuring electronic health records remain protected
- lack of clarity on malpractice and liability concerns
- Medicaid and private payers have inconsistent policies on reimbursements
- Medicare only covers people in some rural regions
- individuals should meet with practitioners licensed in the state where they are in at the time of the visit

A person may use a platform that keeps track of their expenses and documents receipts required by their payers. They should also keep up to date with their insurer’s allowable reimbursements.
Clinics and hospitals must have a robust electronic health record (EHR) system to ensure data privacy and security. Doctors and patients should also ensure that they have a secure network connection and that the mode of delivery is easy to understand.
More importantly, since doctors rely on a person’s report, they must ask more questions to gain a more comprehensive medical history of their patient.
Practitioners need to be aware of their state’s regulations since most regulations on telemedicine vary across states.
