The COVID-19 pandemic has pushed us all into the ether. We’re working online, shopping online and even having family gatherings online. It has also accelerated the move from traditional medical appointments to virtual doctor visits, referred to as telehealth or telemedicine.

Telehealth is the use of electronic information and telecommunications technologies to support and promote long-distance clinical health care, patient and professional health-related education, public health and health administration (Source: U.S. Department of Health and Human Services). Telemedicine is a specific branch of telehealth focused on facilitating health professionals to provide services to patients who are in remote locations. It involves using advanced telecommunication to consult with patients and transfer medical data and information, such as high-resolution images and videos needed for consultation, diagnosis, treatment and monitoring of the patients.

Some of the advantages of telemedicine are listed below:

  • Lower treatment costs
  • Improved healthcare access in remote areas and to those with mobility issues
  • 24/7 access to specialists
  • Improved patient experience by reducing wait and travel times
  • Improved efficiency of healthcare systems by reducing visits to emergency rooms and hospitalization
  • Improved quality of healthcare

Telemedicine is not a new concept. It was envisioned as early as 1924 when science fiction writer, Hugo Gernsback, described a tool he called “teledactyl”, configured with robotic fingers and a video projection feed to examine a patient from afar. Recent advances in information and communication technology have made such long distance approaches possible. However, the general adoption of telemedicine has been thwarted by various barriers such as government regulations, low interest amongst existing practitioners, reimbursement difficulty for patients and insurance providers and the need for stringent data privacy rules. Additional roadblocks include the cost of the technology, a perceived increased risk of misdiagnosis, the lack of awareness of telemedicine services and technical competence among patients to use telemedicine services. These barriers have become minor bumps in the road in the wake of COVID-19, which has made remote healthcare services, a necessary tool in the fight against the virus.

A review of patents and patent applications related to telemedicine revealed that innovations in this space can be broadly categorized under one or more of the following areas: (1) Consultation and Scheduling, (2) Telediagnosis, (3) Remote Monitoring, (4) Treatment, and (5) Non-Clinical – Mentoring, Research, Analytics, EMR, etc. Let’s take a closer look at these areas.

  1. Consultation and Scheduling
  2. Telediagnosis
  3. Remote Monitoring
  4. Treatment
  5. Non-Clinical

A Body-worn ECG Monitoring System that Measures ECG Information and Wirelessly Transmits it to an Internet-based System Associated with the System

Telemetry systems used for providing medical health services aid the physician to collect data from patients, conduct research, and perform analysis on the data. Internet based systems, such as the one disclosed by Baxter Healthcare in U.S. patent 9282894 collects data seamlessly from a patient before, during, and after a cardiovascular procedure such as electrophysiology. The system collects information describing the patient’s response to programmed electrical stimulation (PES) and the ablation process, ECG waveforms and other features, such as cardiac arrhythmias, patient demographics, and patient outcomes. Once the data is collected, the system stores it on an internet-accessible computer system that can deploy a collection of user-selected and custom-developed algorithms. Before and after the procedure, the system also integrates with body-worn and/or implanted devices to collect similar data while the patient is either ambulatory, or in a clinic associated with a hospital. The figure above, depicts a body-worn ECG monitoring system that measures ECG information and wirelessly transmits it to an associated internet-based system.
