Mobile point-of-care MRI demonstration of a normal volunteer in a telemedicine-equipped ambulance.

OBJECTIVE: Several centers have implemented ambulances equipped with CT scanners and telemedicine capabilities, known as mobile stroke units (MSU), to expedite acute stroke care delivery in the pre-hospital setting. While MSUs have been shown to improve outcomes compared with standard emergency medical management, there are limitations to incorporating CT, including radiation exposure to emergency medical services personnel. Recently, a portable, low-field strength MRI (Swoop®, Hyperfine, Inc., Guilford, CT) received FDA clearance for in-hospital use. Here, as proof-of-concept, we explore the possibility of performing MRI in a telemedicine-equipped ambulance during active transport. MATERIALS AND METHODS: In this initial technical demonstration, we imaged an MR phantom and a normal human volunteer using a standard stroke protocol during active ambulance transport. RESULTS: Images of the MR phantom and volunteer were successfully obtained and were immediately available for viewing in the hospital PACS system. The images were deemed of diagnostic quality by the radiologist. Active motion correction maintained superior image quality despite vehicle and scanner motion. In-plane, low contrast resolution of greater than 4 × 4 mm was achieved. Average transmit speeds were calculated to be 3.54 Megabits/second and upload data rates varied while in transit ranging from 8.54 to 4.13 Megabits/second. CONCLUSION: While MRI is not yet ready for clinical use in the MSU setting, our initial experience suggests potential technological feasible of this approach following future technical and MRI sequence development. Additional studies, incorporating patients, would be required to determine clinical feasibility.

Clinical and Technical Considerations of an Open Access Telehealth Network in South Carolina: Definition and Deployment.

BACKGROUND: Today, telehealth is experiencing exponential growth in utilization. Paralleling this trend is the growth in the telehealth industry, with sharp increases in the number of platforms, functionalities, and levels of integrations within both the electronic health record and other technical systems supporting health care. When a telehealth network is intended to be used across independent health care systems, an additional layer of complexity emerges. In the context of regionalized telehealth networks that are not within the same health care system, not only are technical interoperability challenges a practical barrier, but administrative, clinical, and competitive elements also quickly emerge, resulting in fragmented, siloed technologies. OBJECTIVE: The study aimed to describe a statewide approach to deploying an interoperable open access telehealth network across multiple health systems. METHODS: One promising solution to the abovementioned concerns is an open access telehealth network. In the field of telehealth, an open access network (OAN) can be defined as a network infrastructure that can be used by health care providers without a closed or proprietary platform, specific obligatory network, or service-specific telehealth technologies. This framework for the development of an OAN is grounded in practical examples of clinical programs that function in each stage of network maturity based on the experience of the South Carolina Telehealth Alliance (SCTA). The SCTA's experience details successes and challenges in an ongoing effort to achieve an OAN. The model describes an OAN in stages of collaborative maturity and provides insights into the technological, clinical, and administrative implications of making the collaboration possible. RESULTS: The four stages of an OAN are defined according to operational maturity, ranging from feasibility to demonstration of implementation. Each stage is associated with infrastructure and resource requirements and technical and clinical activities. In stage 1, technical standards are agreed upon, and the clinical programs are designed to utilize compliant technologies. In stage 2, collaboration is demonstrated through technical teams working together to address barriers, whereas clinical and administrative teams share best practices. In stage 3, a functional interoperable network is demonstrated with different institutions providing service through common telehealth end points at different patient care sites. In stage 4, clinical workflows are streamlined and standardized across institutions, and economies of scale are achieved through technical and administrative innovations. CONCLUSIONS: The approach to OAN development described provides a roadmap for achieving a functional telehealth network across independent health systems. The South Carolina experience reveals both successes and challenges in achieving this goal. The next steps toward the development of OANs include advocacy and ongoing engagement with the developers of telehealth technologies regarding their commitment to interoperability.

Hurricane Impact on Emergency Services and Use of Telehealth to Support Prehospital Care.

The impact of hurricanes on emergency services is well-known. Recent history demonstrates the need for prehospital and emergency department coordination to serve communities during evacuation, storm duration, and cleanup. The use of telehealth applications may enhance this coordination while lessening the impact on health-care systems. These applications can address triage, stabilization, and diversion and may be provided in collaboration with state and local emergency management operations through various shelters, as well as during other emergency medical responses.
