The telecommunication revolution in the medical field: present applications and future perspective

Improving forensic healthcare: ARMED, a new telemedical examination

BACKGROUND

the Istanbul Convention demands care to victims of violence while upholding forensic standards. Victims, however, often seek medical help at hospitals where the availability of forensic experts is limited. This results in overlooked injuries and lost or damaged evidence, ultimately impacting court proceedings and identification of individuals at risk. The aim of this paper was to establish real-time remote guidance for distant physicians during the forensic examination of violence victims.

METHODS

Augmented Reality Assisted Medical Evidence Collection and Documentation (ARMED) was established in Heidelberg at the Institute for Forensic and Traffic Medicine (IFTM) in 2023 as an innovative telementoring model. Video-teleconferencing components including a head-mounted device (HMD), a customized software package, hardware devices, and a data management portal were employed to facilitate seamless expert care delivery, data sharing, and to ensure privacy and confidentiality. ARMED platform was evaluated in three partner hospitals with parameters including internet connection stability, clarity of live-streaming and audio-visual communication, the quality of photos, and the safety of data management.

RESULTS

The combination of RealWear Navigator 500 as HMD, a customized version of videoconferencing software, and a portal server system for safe and secure patient data management constituted a robust, user-friendly, and practical telemedicine solution.

CONCLUSION

ARMED facilitates real-time communication between healthcare providers and forensic experts, enhancing their ability to recognize and detect injuries effectively. This holds the potential to significantly improve the process of evidence collection for documenting cases of violence, ultimately aiding in the pursuit of justice and the protection of victims.

5G mobile communication applications for surgery: An overview of the latest literature

Fifth-generation wireless network, 5G, is expected to bring surgery to a next level. Remote surgery and telementoring could be enabled and be brought into routine medical care due to 5G characteristics, such as extreme high bandwidth, ultra-short latency, multiconnectivity, high mobility, high availability, and high reliability. This work explores the benefits, applications and demands of 5G for surgery. Therefore, the development of previous surgical procedures from using older networks to 5G is outlined. The current state of 5G in surgical research studies is discussed, as well as future aspects and requirements of 5G in surgery are presented.

Factors Affecting Use of Telemedicine and Telesurgery in Cancer Care (TTCC) among Specialist Physicians

Background: Considering the increasing incidence of different cancers, use of modern technologies such as TTCC can make a dramatic change in treatment of these diseases. So, if the evolution strategy conflicts with the organizational culture, national culture, and organizational structure of experts in this field, resistance will rise. Objective: The purpose of this study was to determine the effective factors on the use of TTCC in hospitals affiliated to Tehran University of Medical Sciences using the AHP model. Materials and Methods: This current descriptive study was carried out in 2018 on specialist physicians from five hospitals of Tehran University of Medical Sciences. The data gathering tool was a questionnaire consisting of two sections; demographic items and 27 effective factors influencing the implementation of TTCC technology, which was evaluated for validity and reliability. Data analysis was performed using analytical hierarchy process with expert choice and for empirical illustration are used to discuss the use of covariance-based SEM versus smart PLS software. Results: Based on AHP comparisons in the studied factors, the highest priority was the Cultural factor. In other words, commitment of senior executives to support the provision of a new technology with a weight of 0.327. The lowest priority, however, was related to support diverse approaches, innovation, creativeness, and acceptance of new ideas with a weight of 0.038. In regard with technical and organizational factors, out-of-hospital access to the intranet network and support provided by the doctors, with the weight of 0.221 and 0.205 in order, acquired the highest rates. Conclusion: Considering the high prevalence of cancer in Iran and the necessity of using new technologies in its treatment and by addressing the specialists’ views and opinions in this field, organizational and national culture in the application of TTCC technology should be promoted. This target can be hit through acceptance, change in attitude, and successful use of TTCC technology by medical professionals.

Effectiveness of Telementoring in Surgery Compared With On-site Mentoring: A Systematic Review

BACKGROUND

Mentorship is important but may not be feasible for distance learning. To bridge this gap, telementoring has emerged. The purpose of this systematic review was to evaluate the effectiveness of telementoring compared with on-site mentoring.

METHODS

A search was done up to March 2015. Studies were included if they used telementoring between surgeons during a clinical encounter and if they compared on-site mentoring and telementoring.

RESULTS

A total of 11 studies were included. All reported no difference in complication rates, and 9 (82%) reported similar operative times; 4 (36%) reported technical issues, which was 3% of the total number of cases in the 11 studies. No study reported on higher levels of evidence for effectiveness of telementoring as an educational intervention.

CONCLUSION

Studies reported that telementoring is associated with similar complication rates and operative times compared with on-site mentoring. However, the level of evidence to support the effectiveness of telementoring as a training tool is limited. There is a need for studies that provide evidence for the equivalence of the effectiveness of telementoring as an educational intervention in comparison with on-site mentoring.

Telesimulation: An Innovative Tool for Health Professions Education

Telesimulation is a new and innovative concept and process that has been used to provide education, training, and assessment in health-related fields such as medicine. This new area of simulation, and its terminology, has its origins within the past decade. The face validity and ability to provide the benefits of simulation education to learners at off-site locations has allowed the wide and rapid adoption of telesimulation in the field of medical education. Telesimulation has been implemented in areas such as pediatric resuscitation, surgery, emergency medicine, ultrasound-guided regional anesthesia in anesthesiology, nursing, and neurosurgery. However, its rapid expansion and current use has outgrown its recent description less than a decade ago. To date, there is no unifying definition of telesimulation that encompasses all the areas where it has been used while simultaneously allowing for growth and expansion in this field of study. This article has two main objectives. The first objective is to provide a comprehensive and unifying definition of telesimulation that encompasses all the areas where it has been used while allowing for growth and expansion in the field of study. The secondary objective is to describe the utility of telesimulation for emergency medicine educators in the context of the current evidence to serve as a background and framework that educators may use when considering creating educational programs that incorporate telecommunication and simulation resources. This article is complementary to the large group presentation where this new comprehensive and unifying definition was introduced to the simulation community at the International Meeting on Simulation in Healthcare in January 2016.

An evaluation of a surgical telepresence system for an intrahospital local area network

summary

We evaluated a digital telepresence system in an operating theatre (OR) environment which enabled a consultant to join the surgical team from a remote site by audiovisual communication. The system is based on video transmission using a streaming technique, with a server and a client connected via a local area network (LAN). Two cameras can be remotely controlled: one camera is built into the OR lamp and a second, laparoscopic camera is mounted on a robotic arm. Another feature of the system is teledemonstration, which permits the remote consultant to demonstrate points of particular interest. We evaluated the system clinically in 237 cases. In 28 cases (12%), telepresence could not be established for various reasons, mainly human failure. In 42 cases (18%), the full potential of telepresence was used. Technical evaluation showed that a data rate of 2 Mbit/s provides sufficient audio and video quality, as well as reliable teledemonstration. The data transmission delay was acceptable for clinical purposes (video 0.92 s, audio 0.6s from OR to client, audio 0.7s from client to OR). The study showed that telepresence is a promising means of providing highly specialized expertise within the OR.

Patient-Clinician Communication: The Roadmap for HCI

Effective communication between patients and their clinicians during clinical encounters has a positive impact on health outcomes. Technology has the potential to help transform this synchronous interaction, but researchers are still at early stages of developing interventions to assess and improve patient-clinician communication. In this workshop, we envision opening up a dialogue among researchers and clinicians who wish to discuss directions for future research in this domain. In particular, the workshop will focus on exploring how technologies available today, as well as projected for the future, can support the communication needs of clinicians and patients.

Safe introduction of a new surgical technique: remote telementoring for posterior retroperitoneoscopic adrenalectomy

BACKGROUND

Posterior retroperitoneoscopic adrenalectomy (PRA) is a safe and effective approach to adrenalectomy, offering less pain and faster recovery than open or laparoscopic surgery. Although the popularity of PRA is increasing, few surgical centres have extensive experience with the procedure. The ideal approach to achieve proficiency with any new technique involves on-site observation of an experienced surgeon-mentor, followed by mentored hands-on experience of the surgeon-learner. However, it is not always feasible for a surgeon-mentor to offer on-site supervision to the surgeon-learner in his or her home institution. Advances in Internet applications have made remote telementoring a viable alternative to on-site mentoring in selected situations.

METHODS

We describe our experience in safely introducing PRA to Melbourne, Australia, where no highly experienced surgeon-mentors were available. A surgeon with experience of 12 PRA procedures attended from interstate, along with live telementoring via Skype video link by an overseas surgeon who had performed more than 200 PRA procedures, to mentor the surgeon-learner performing her first three cases.

RESULTS

The operating surgeon's first three PRA procedures proceeded uneventfully, with no complications, relatively short operative times and one-night hospital stays for all three patients. Twenty-two more have been performed since, without complications.

CONCLUSION

Remote telementoring is a safe and feasible way to assist surgeons in safely introducing new techniques. This strategy is particularly applicable in centres where no surgeon-mentor is locally available. It is important that the surgeon-learner has the skills and experience to complete the procedure using alternative techniques in the case of complications or technical failure.

The value of microsurgery in liver research

The use of an operating microscope in rat liver surgery makes it possible to obtain new experimental models and improve the already existing macrosurgical models. Thus, microsurgery could be a very valuable technique to improve experimental models of hepatic insufficiency. In the current review, we present the microsurgical techniques most frequently used in the rat, such as the portacaval shunt, the extrahepatic biliary tract resection, partial and total hepatectomies and heterotopic and orthotopic liver transplantation. Hence, reducing surgical complications allows for perfecting the resulting experimental models. Thus, liver atrophy related to portacaval shunt, prehepatic portal hypertension secondary to partial portal vein ligation, cholestasis by resection of the extrahepatic biliary tract, hepatic regeneration after partial hepatectomies, acute liver failure associated with subtotal or total hepatectomy and finally complications derived from preservation or rejection in orthotopic and heterotopic liver transplantation can be studied in more standardized experimental models. The results obtained are therefore more reliable and facilitates the flow of knowledge from the bench to the bedside. Some of these microsurgical techniques, because of their simplicity, can be performed by researchers without any prior surgical training. Other more complex microsurgical techniques require in-depth surgical training. These techniques are ideal for achieving a complete surgical training and more select microsurgical models for hepatology research.

The future of robotics in hand surgery

Robotics has spread over many surgical fields over the last decade: orthopaedic, cardiovascular, urologic, gynaecologic surgery and various other types of surgery. There are five different types of robots: passive, semiactive and active robots, telemanipulators and simulators. Hand surgery is at a crossroad between orthopaedic surgery, plastic surgery and microsurgery; it has to deal with fixing all sorts of tissues from bone to soft tissues. To our knowledge, there is not any paper focusing on potential clinical applications in this realm, even though robotics could be helpful for hand surgery. One must point out the numerous works on bone tissue with regard to passive robots (such as fluoroscopic navigation as an ancillary for percutaneous screwing in the scaphoid bone). Telemanipulators, especially in microsurgery, can improve surgical motion by suppressing physiological tremor thanks to movement demultiplication (experimental vascular and nervous sutures previously published). To date, the robotic technology has not yet become simple-to-use, cheap and flawless but in the future, it will probably be of great technical help, and even allow remote-controlled surgery overseas.

Evolving role and current state of robotics in minimally invasive gynecologic surgery

Advancements in conventional laparoscopy afford gynecologists the ability to treat disease with minimally invasive interventions. Procedures such as hysterectomy are still performed predominantly via laparotomy. Instrumentation, complex disease, and steep learning curves are often cited as obstacles to minimally invasive surgery. The advent of robotic technology may provide a means to overcome the limitations of conventional laparoscopy through the use of 3-dimensional imaging and more dextrous and precise instruments. Current studies clearly demonstrate the feasibility and safety of applying robotics to the entire spectrum of gynecologic procedures. Rigorous scientific studies and long-term data are needed to determine the appropriate applications of robotics in gynecology. Numerous questions still exist pertaining to costs, credentialing and privileging, and training.

Remote video management for intraoperative consultation and surgical telepresence

Telemedicine applications can connect surgeons from one operating room (OR) to a distant consultant. The additional capacity of telepresence provides remote consultants the ability to control their own view of the surgical field using robotic management of a network camera. The goal of this study was to compare access to surgical field by robotic camera versus image controlled by the surgeon using a camera mounted to the table. A Stryker laparoscopic camera was attached to the OR table using a Mediflex arm, and video image was transmitted with a Polycom Transfer Control Protocol (TCP)/Internet Protocol (IP) connection. A network Sony camera was mounted on a tripod, connected over the Internet using a parallel TCP/IP connection. A Web interface allowed control of the camera angle and zoom. In 22 consultations effective bandwidth was 800 Kbps for the network camera and 1024 Kbps for the Stryker camera. The operation was thyroidectomy and the consultant was either in Moscow, Russia, or Bucharest, Romania. The quality of the image in both methods was indiscernible. The ability to identify critical surgical anatomy was also indiscernible. No transmission session failed or had an interruption. The robotic camera can be a powerful tool for surgical collaboration.

Telemedicine and Electronic Health Information for Clinical Continuity in a Mobile Surgery Program

INTRODUCTION

An intermittent surgical services program in rural Ecuador was able to benefit from close collaboration between surgeons and primary care physicians through the use of telemedicine technologies.

METHODS

Inexpensive telemedicine workstations capable of patient documentation, imaging, and video-conferencing at extremely low bandwidth were established in collaborative primary care sites in rural Ecuador. Patients were screened for intermittent surgical services by primary caregivers according to the surgeons' guidelines. Real-time and store-and-forward telemedicine allowed appropriate collaborative, informed decision-making. Surgery was performed, and postoperative care was similarly handled by on-site, familiar primary caregivers.

RESULTS

To date, this system has been used in more than 124 patient encounters (74 preoperative and 50 postoperative visits). The system allowed advance screening of patients on the part of the surgeons, leading to cancellations for 9 patients. Postoperatively, the system allowed 100% concurrence in postoperative diagnoses between the primary caregivers and the surgeons.

CONCLUSIONS

Inexpensive, low-bandwidth telemedicine solutions can support intermittent surgical services by providing patients to have contact with specialist care through their familiar, local primary caregivers.

Telementoring in Endocrine Surgery: Preliminary Indian Experience

Telemedicine is starting to play an important role in the health field in India. In this case report we describe the successful use of telementoring to remove a parathyroid tumor in a patient with residual hyperparathyroidism after two previous unsuccessful attempts in tumor excision. A 21-yr-old patient crippled with advanced hyperparathyroidism was taken up for third-time exploration at Amrita Institute of Medical Sciences (AIMS), Kochi, with guidance from the Sanjay Gandhi Postgraduate Institute of Medical Sciences (SGPGIMS), Lucknow, using telemedicine technology. These two centers are located 2,500 km apart, and telementoring from the more experienced endocrine surgeons at SGPGIMS resulted in successful tumor localization and removal. For this session both the institutions were provided with a dedicated 512 Kbps very small aperture terminal (VSAT) link and two-way video-audio connectivity. Even though two previous explorations were unsuccessful, with the help of telemedicine technology the same surgeon was successful in locating and removing the tumor. The video and audio quality was of good enough quality for the expert at SGPGIMS to guide the team at AIMS satisfactorily. The patient benefited since he did not have to travel to a far-off specialized center for surgery. This case report testifies to the usefulness of telemedicine in the field of surgery, especially in developing countries, which have few medical experts in certain specialized areas.

Telemedicine and robotics: paving the way to the globalization of surgery

The concept of delivering health services at a distance, or telemedicine is becoming an emerging tool for the field of surgery. For the surgical services, telepresence surgery through robotics is gradually being incorporated into health care practices. This article will provide a brief overview of the principles surrounding telemedicine and telepresence surgery as they specifically relate to robotics. Where limitations have been reached in laparoscopy, robotics has allowed further steps forward. The development of robotics in medicine has been a progression from passive to immersive technology. In gynecology, the utilization of robotics has evolved from the use of Aesop, a robotic arm for camera manipulation, to full robotic systems such as Zeus, and the daVinci surgical system. These systems have not only been used directly for a variety of procedures but have also become a useful tool for conferencing and the mentoring of surgeons from afar. As this mode of technology becomes assimilated into the culture of surgery and medicine globally, caution must be taken to carefully navigate the economic, legal and ethical implications of telemedicine. Despite the challenges faced, telepresence surgery holds promise for more widespread applications.

Technical Controversies in Fundoplication Surgery

Gastroesophageal reflux disease (GERD) is a common health problem affecting more than 50% of the population. For those who experience more than occasional symptoms, GERD has a profound effect on their quality of life. With the advent of laparoscopic surgery, fundoplication has been used to treat GERD. Fundoplication also is used in the surgical management of paraesophageal hernias. Technical controversies are addressed in this article, including open versus laparoscopic approaches, the choice of complete (360 degres) or partial fundoplication, whether or not a gastroplasty is required, and the use of prosthetic materials in crural repair.
