Enabling the Mission Through Trans-Atlantic Remote Mentored Musculoskeletal Ultrasound: Case Report of a Portable Hand-Carried Tele-ultrasound System for Medical Relief Missions

Abstract

Modern medical practice has become extremely dependent upon diagnostic imaging technologies to confirm the results of clinical examination and to guide the response to therapies. Of the various diagnostic imaging techniques, ultrasound is the most portable modality and one that is repeatable, dynamic, relatively cheap, and safe as long as the imaging provided is accurately interpreted. It is, however, the most user-dependent, a characteristic that has prompted the development of remote guidance techniques, wherein remote experts guide distant users through the use of information technologies. Medical mission work often brings specialist physicians to less developed locations, where they wish to provide the highest levels of care but are often bereft of diagnostic imaging resources on which they depend. Furthermore, if these personnel become ill or injured, their own care received may not be to the standard they have left at home. We herein report the utilization of a compact hand-carried remote tele-ultrasound system that allowed real-time diagnosis and follow-up of an acutely torn adductor muscle by a team of ultrasonographers, surgeons, and physicians. The patient was one of the mission surgeons who was guided to self-image. The virtual network of supporting experts was located across North America, whereas the patient was in Lome, Togo, West Africa. The system consisted of a hand-carried ultrasound, the output of which was digitized and streamed to the experts within standard voice-over-Internet-protocol software with an embedded simultaneous videocamera image of the ultrasonographer's hands using a customized graphical user interface. The practical concept of a virtual tele-ultrasound support network was illustrated through the clinical guidance of multiple physicians, including National Aeronautics and Space Administration Medical Operations remote guiders, Olympic team-associated surgeons, and ultrasound-focused emergentologists.

The use of portable ultrasound devices in low‐ and middle‐income countries: a systematic review of the literature

“…Another study from India assessed the feasibility of cervical ultrasound to detect cervical spine fractures in children . Hand‐carried ultrasound has been successfully used for surgical patient selection across a broad spectrum of diseases, such as abdominal tumours and congenital malformations, as well as for telemedicine‐guided diagnosis in rural areas .…”

Joint Recommendations and Resources for Clinical Ultrasound Education Amidst the COVID‐19 Era

“…The fellow can continue mastering educational skills when not physically present using well-described do-it-yourself methods of remote monitoring or new technologies that offer teleguidance features. 20,21 • Develop novel teaching opportunities. Fellows may give virtual presentations to residents and rotators during weekly conferences.…”

The need for a robust 24/7 subspecialty “clearing house” response for telementored trauma care

“…Initial experiences have shown that smartphones are incredibly powerful and might enable global telemedical outreach on an unprecedented scale. 8 Traditionally, Canadians have welcomed a presence in international security missions, and this presence has often been heavily weighted to emphasize medical support in multinational military collaborations. Providing the backbone for a temporary or better permanent telementoring network infrastructure might conceivably be a deliverable that would fit well with Canada's geopolitical resources and philosophies and a task that might further justify the existence of subspecialist physicians with the CF.…”
