Low Earth Orbit Communication Satellites: A Positively Disruptive Technology That Could Change the Delivery of Health Care in Rural and Northern Canada

Canada is a progressive nation that endeavors to provide comprehensive, universal, and portable health care to all its citizens. This is a challenge for a country with a population of 40 million living within a land expanse of 10 million km2 and where 18% live in rural or highly remote locations. The combined population of Yukon, Northwest Territories, and Nunavut is only 128,959 (0.32% of the population), living within 3.92 million km2, and many of these citizens live in isolated communities with unique health needs and social issues. The current solution to providing health care in the most remote locations has been to transport the patient to the health care provider or vice versa, which incurs considerable financial strain on our health care system and personal stress to the patient and provider. The recent global deployment of low Earth orbit communication satellites (LEO-ComSats) will change the practice and availability of online medicine everywhere, especially in northern Canada. The deployment of LEO-ComSats could result in disruptive but positive changes in medical care for underserved communities in remote geographic locations across Canada. LEO-ComSats can be used to demonstrate online medical encounters between a patient and a doctor in Canada, separated by thousands of kilometers. Most certainly, the academic medical centers in lower Canada could perform online telementored medical care to our northern communities like the remote care provided to many Canadians during the COVID-19 pandemic. An online health care model requires effective design, testing, and validation of the policies, standards, requirements, procedures, and protocols. Although the COVID-19 pandemic was the initial prime mover across all of Canada in the use of online medical encounters and creating rapidly devised reimbursement models, it was nonetheless created reactively, using real-time managerial fiat and poorly defined procedures based on minimal pedagogical experience, which made it "difficult to prove it was universally safe." It is essential to proactively derive the medical policies, standards, and procedures for telementored medicine and "prove it is safe" before LEO-ComSat technology is ubiquitously deployed in northern Canada. This viewpoint was written by subject matter experts who have researched online and internet-based medicine for many years, sometimes 3 decades. In many cases, a literature review was not necessary since they already had the articles in the bibliography or knowledge in their possession. In many cases, internet search engines (ie, Google or PubMed) and Canadian government documents were used to provide corroborating evidence.

Point-of-care resuscitation research: From extreme to mainstream: Trauma Association of Canada Fraser Gurd Lecture 2019

The Gurd Family surgical legacy was deeply intertwined with National service in both World Wars. My own personal research mission has attempted to emulate such service, by enhancing the tools and techniques available to facilitate point-of-care diagnosis and resuscitation in extreme and adverse environments. Our efforts involving point-of-care diagnosis/resuscitation and the telementored guidance of those remotely responding to catastrophic injury have included collaborations with National Aeronautics and Space Administration (NASA) the Canadian Space Agency, the Canadian Forces, its democratic allies, and non-governmental surgical organizations. Research has been conducted in resuscitative suites and operating theaters, research laboratories, parabolic flight aircraft, on humanitarian surgical missions, and from ski-hills and firehalls. The initial phases of these efforts involved inaugural studies in resuscitative sonography including defining the Extended Focused Assessment with Sonography for Trauma (EFAST) examination. Although the original work was commissioned for Space Medicine, generalization to mainstream practice further justifies space medicine research. Iterative steps in advancing telementored resuscitation have subsequently involved the maturation of space-mandated telementored ultrasound support (TMUS), exploration of TMUS in terrestrial clinical practice, and the creation of increasingly mobile (hand-held) TMUS solutions. Subsequently it was recognized that teleultrasound is simply one informatic dimension of remote telemedicine, and current efforts are focused in a Program known as TeleMentored Ultrasound Supported Medical Interactions (TMUSMI) of remote responders required to intervene with catastrophic trauma. While this research program has yielded many techniques and findings that have benefited mainstream terrestrial practice, these investigations are currently ongoing, and we hope to demonstrate that TMUSMI may benefit all Canadians especially those in remote areas, as well as potentially every global inhabitant without immediate access to care. Further, we propose that to fully utilize these techniques, a new specialty, that of the remote medical mentor will be required, a new specialty that will require the creation and scientific validation of its principles and techniques.

Trauma in Canada: a spirit of equity & collaboration

BACKGROUND

The delivery of equitable trauma care in Canada is not without challenges within our universal health care system. Notably, the tyranny of geography is intermittently at odds with adequate access for our rural, indigenous, and impoverished populations. Other differences exist when compared with neighbouring trauma systems, for example in the United States.

METHODS

As a critical review, we chose to compare and critique the overall system of trauma organization and perceived societal expectations of a high-income, North American country (Canada) to assist with discussions on trauma systems for the future.

RESULTS

Tele-technology is providing some early solutions. Trauma systems and delivery of care in Canada differ from the United States due to our single-payer system, regionalization and universal provision. Care for injured Canadians has a long history of being multidisciplinary, with collaborative research programs. Canada also has a history of global surgical endeavours, beginning with Dr. Norman Bethune and his recognition of the political causes of trauma and continuing as a global public health concern for all.

CONCLUSIONS

While challenges continue to exist for the provision of equitable trauma care in Canada, unique multidisciplinary, collaborative and technology-based solutions continue to be developed, both locally and globally, to address this critical public health issue.

Clinician performed resuscitative ultrasonography for the initial evaluation and resuscitation of trauma

BACKGROUND

Traumatic injury is a leading cause of morbidity and mortality in developed countries worldwide. Recent studies suggest that many deaths are preventable if injuries are recognized and treated in an expeditious manner - the so called 'golden hour' of trauma. Ultrasound revolutionized the care of the trauma patient with the introduction of the FAST (Focused Assessment with Sonography for Trauma) examination; a rapid assessment of the hemodynamically unstable patient to identify the presence of peritoneal and/or pericardial fluid. Since that time the use of ultrasound has expanded to include a rapid assessment of almost every facet of the trauma patient. As a result, ultrasound is not only viewed as a diagnostic test, but actually as an extension of the physical exam.

METHODS

A review of the medical literature was performed and articles pertaining to ultrasound-assisted assessment of the trauma patient were obtained. The literature selected was based on the preference and clinical expertise of authors.

DISCUSSION

In this review we explore the benefits and pitfalls of applying resuscitative ultrasound to every aspect of the initial assessment of the critically injured trauma patient.

Resuscitative Long-Bone Sonography for the Clinician: Usefulness and Pitfalls of Focused Clinical Ultrasound to Detect Long-Bone Fractures During Trauma Resuscitation

Bone has one of the highest acoustic densities (AD) in the human body. Traditionally, bone has been considered to be a hindrance to the use of ultrasound (US), as US waves are reflected by the dense matrix and obscure underlying structures. The intense wave reflection, however, can clearly illustrate the cortical bony anatomy of long bones, making cortical disruption obvious. Ultrasound can be used at the bedside concurrently with the overall trauma resuscitation, and may potentially limit the patient's and treating team's exposure to ionizing radiation, corroborate clinical findings, and augment procedural success. The extended focused assessment with sonography for trauma (EFAST) is an essential tool in the resuscitation of severe torso trauma, frequently demonstrating intra- pericardial and intra-peritoneal fluid, inferring hemo/pneumothoraces, and demonstrating cardiac function. Although it is typically considered as a diagnosis of exclusion, multiple long-bone fractures may be a source of shock and can be quickly confirmed at the bedside with EFAST. Further, the early detection of long-bone fractures can also aid in the early stabilization of severely injured patients. Sonographic evaluation for long-bone fractures may be particularly useful in austere environments where other imaging modalities are limited, such as in the battlefield, developing world, and space. While prospective study has been limited, selected series have demonstrated high accuracy among both physician and para-medical clinicians in detecting long-bone fractures. Pitfalls in this technique include reduced accuracy with the small bones of the hands and feet, as well as great reliance on user experience.
