Comparing sources of disruptions to telemedicine-enabled stroke care in an ambulance.
This study investigated the nature and source of disruptions in an ambulance during the telemedicine-based caregiving process for stroke patients to enhance the ambulance design for supporting telemedicine-based care. Thirteen simulated telemedicine-based stroke consults were video recorded and then coded and analyzed using an existing systems-based flow disruption (FD) taxonomy. Factors that impacted disruptions included seat size, arrangement of assessment equipment, location of telemedicine equipment, and design of the telemedicine camera. The left ambulance seat zone and head of the patient bed had more environmental hazard-related disruptions, while the right zone was more prone to interruptions and communication-related disruptions.

Applications and user perceptions of smart glasses in emergency medical services: semistructured interview study.
This study’s aim was to understand the potential of smart glasses to support the work practices of prehospital providers, such as emergency medical services (EMS) personnel. The authors conducted semistructured interviews with 13 EMS providers recruited from 4 hospital-based EMS agencies in an urban area in the east coast region of the United States. Interview question topics included EMS workflow, challenges encountered, technology needs, and users' perceptions of smart glasses in supporting daily EMS work. During the interviews, they demonstrated a system prototype to elicit more accurate and comprehensive insights regarding smart glasses. They identified four potential application areas for smart glasses in EMS: enhancing teleconsultation between distributed prehospital and hospital providers, semiautomating patient data collection and documentation in real time, supporting decision-making and situation awareness, and augmenting quality assurance and training. Voice commands and hand gestures were indicated as the most preferred and suitable interaction mechanisms as compared to using a built-in touch pad. EMS providers expressed positive attitudes toward using smart glasses during prehospital encounters, however several potential barriers and user concerns need to be considered and addressed before implementing and deploying smart glasses in EMS practice. These barriers include hardware limitations, human factors, reliability, workflow, interoperability, and privacy.

An exploratory study investigating the barriers, facilitators, and demands affecting caregivers in a telemedicine integrated ambulance-based setting for stroke care.
This study investigates the impact of telemedicine on workload, teamwork, workflow, and communication of geographically distributed caregivers delivering stroke care in ambulance-based telemedicine. Simulated stroke sessions were conducted with selected caregivers, then followed with a survey and interviews. Findings showed that barriers included frustration with equipment, the loss of personal connection of the neurologists with the patients, and physical constraints in the ambulance. Facilitators included live visual communication increasing teamwork and efficiency, the ease of access to neurologist, increased flexibility, and high overall satisfaction and usability.

Delays in recognition of the need for telephone-assisted CPR due to caller descriptions of chief complaint.
The objective of this study was to test if caller descriptions of chief complaint delays emergency medical dispatchers' (EMDs) recognition of the need for telephone-assisted CPR (T-CPR). The investigators conducted an analysis of N = 433 cardiac arrest calls from six large call centers in the United States. They concluded that caller chief complaint description affected the time to recognition of the need for T-CPR.
