Abstract:
Telemedicine has the potential to help bridge the time and distance gaps that can mean life or death for some patients. It can provide live video conferencing between local, rural doctors and clinics to the necessary specialists at a major hospital or research center. These conferences can provide quick and accurate diagnosis and save both the patient and the doctor time and money. This article presents a background on telemedicine including components, applications and benefits of telemedicine, challenges and trends in telemedicine, and conclusion with some direction for future research in telemedicine.Keywords:

Successfully developing telemedicine systems is primarily about effective change management. The literature suggests that certain principles are likely to increase the chances of success in developing a telemedicine system. These are: (1) telemedicine applications and sites should be selected pragmatically, rather than philosophically; (2) clinician drivers and telemedicine users must own the systems; (3) telemedicine management and support should follow best-practice business principles; (4) the technology should be as user-friendly as possible; (5) telemedicine users must be well trained and supported, both technically and professionally; (6) telemedicine applications should be evaluated and sustained in a clinically appropriate and user-friendly manner; (7) information about the development of telemedicine must be shared. If telemedicine is to realize its full potential, it must be properly evaluated and the results of any evaluations published, whether the results are positive or negative. Since telemedicine is about communication with colleagues and patients across large distances, it should be possible for those involved in it to do the same with their experiences.

This report describes our experience using low-and moderate-cost videoconferencing systems for telemedicine. After determining that low-cost systems using a standard personal computer and personal computer camera were unsatisfactory, a demonstration project was carried out using a $4000 self-contained videoconferencing unit (telemedicine in a box), using eight simulated telemedicine consultation scenarios. The quality of the videoconferencing was good for all eight scenarios. All eight consultation simulations demonstrated different ways of improving patient care. Two of the major problems hindering the broad proliferation of telemedicine (high cost and high complexity) are solved by the telemedicine in a box concept. Focussing on the telemedicine in a box concept when planning a telemedicine system will improve its feasibility in the real world of health care.

We developed an integrated model of telemedicine services in emergency medical care. The architecture was designed to support pre-hospital management. The experimental work was carried out with the collaboration of the emergency medical services (EMS) in Madrid. Two different study populations were defined: a control population using conventional EMS protocols and a population using the telemedicine system. The telemedicine system was based on a telepresence service; electrocardiograms and images were transmitted from the ambulance to the health emergency coordination centre. The cost of dealing with 100 patients using telemedicine was €6030 less than the cost of conventional care. The response times using telemedicine were significantly lower.

Early efforts to incorporate telemedicine into Emergency Medicine focused on connecting remote treatment clinics to larger emergency departments (EDs) and providing remote consultation services to EDs with limited resources. Owing to continued ED overcrowding, some EDs have used telemedicine to increase the number of providers during surges of patient visits and offer scheduled "home" face-to-face, on-screen encounters. In this study, we used remote on-screen telemedicine providers in the "screening-in-triage" role.This study aimed to compare the efficiency and patient safety of in-person screening and telescreening.This cohort study, matched for days and proximate hours, compared the performance of real-time remote telescreening and in-person screening at a single urban academic ED over 22 weeks in the spring and summer of 2016. The study involved 337 standard screening hours and 315 telescreening hours. The primary outcome measure was patients screened per hour. Additional outcomes were rates of patients who left without being seen, rates of analgesia ordered by the screener, and proportion of patients with chest pain receiving or prescribed a standard set of tests and medications.In-person screeners evaluated 1933 patients over 337 hours (5.7 patients per hour), whereas telescreeners evaluated 1497 patients over 315 hours (4.9 patients per hour; difference=0.8; 95% CI 0.5-1.2). Split analysis revealed that for the final 3 weeks of the evaluation, the patient-per-hour rate differential was neither clinically relevant nor statistically discernable (difference=0.2; 95% CI -0.7 to 1.2). There were fewer patients who left without being seen during in-person screening than during telescreening (2.6% vs 3.8%; difference=-1.2; 95% CI -2.4 to 0.0). However, compared to prior year-, date-, and time-matched data on weekdays from 1 am to 3 am, a period previously void of provider screening, telescreening decreased the rate of patients LWBS from 25.1% to 4.5% (difference=20.7%; 95% CI 10.1-31.2). Analgesia was ordered more frequently by telescreeners than by in-person screeners (51.2% vs 31.6%; difference=19.6%; 95% CI 12.1-27.1). There was no difference in standard care received by patients with chest pain between telescreening and in-person screening (29.4% vs 22.4%; difference=7.0%; 95% CI -3.4 to 17.4).Although the efficiency of telescreening, as measured by the rate of patients seen per hour, was lower early in the study period, telescreening achieved the same level of efficiency as in-person screening by the end of the pilot study. Adding telescreening during 1-3 am on weekdays dramatically decreased the number of patients who left without being seen compared to historic data. Telescreening was an effective and safe way for this ED to expand the hours in which patients were screened by a health care provider in triage.

One year ago, shortly after the onset of the coronavirus disease 2019 (COVID-19) pandemic, we published our initial experience with telemedicine. We showed that during the early pandemic, there was a dramatic shift to telemedicine and that 70% of our patients would decline telemedicine in favor of an in-person visit. As clinical limitations and stay-at-home orders relaxed, we sought to define how we have used telemedicine since. After the initial month of the pandemic, our utilization of telemedicine fell to an average of only 5% of visits over the past year. Nearly 80% of all telemedicine visits were routine follow-up visits, with its usage being unaffected by local policy and pandemic surges. The usefulness and applications of telemedicine have been well described; however, after our initial reliance on telemedicine, its use has been minimal. Moving forward, attention will need to focus on innovation and expanding comprehensive virtual examinations for otolaryngology to fully embrace this technology.
