Summary
This study addresses the critical need to improve emergency medical services (EMS) response to motor vehicle crashes (MVCs), particularly in rural areas where trauma injuries and fatalities are disproportionately high. The primary motivation was to reduce the adverse impacts of MVC trauma by enhancing the efficiency and effectiveness of information handoff between EMS field personnel and hospital emergency departments (EDs). Existing communication methods, such as synchronous radio calls and delayed electronic patient care records, often result in fragmented, incomplete, or missed information, which can hinder clinical decision-making and patient outcomes. To address this gap, the researchers developed and tested "CrashHelp," a multimedia mobile application designed to allow paramedics to capture and securely transmit voice, video, images, and patient data to EDs in real-time. The research involved a six-month Phase II pilot demonstration of CrashHelp version 2.0 in the greater Boise, Idaho area, conducted from November 2012 to May 2013. The study employed a mixed-methods approach, combining quantitative usage data with qualitative feedback from practitioners. The system allowed 81 paramedics from Ada County, Canyon County, and Homedale Ambulance to send reports to eight hospital EDs. During the pilot, 1,513 CrashHelp reports were transmitted, including 306 digital images and 1,121 voice recordings, though video usage was minimal (five files). The system utilized 3G/4G networks to send data to a middleware subsystem, which notified ED staff via pager, email, or phone. Qualitative data were gathered through group interviews with EMS and ED staff who used the system, assessing ease of use, technical performance, and perceived clinical value. The findings indicated that when used, the system was helpful and well-received by practitioners. EMS and ED staff generally found the interface easy to use and noted that the multimedia information, particularly images and audio recordings, provided valuable insights into patient conditions and incident severity. Participants highlighted advantages over traditional radio communication, such as the ability to record information asynchronously, allowing paramedics to multitask and ED staff to review recordings repeatedly. Images were specifically noted to expedite trauma activation processes by visually validating injury severity. However, the voluntary nature of the pilot led to inconsistent usage over time, limiting the extent to which the information was utilized. The study also noted challenges in integrating the technology into time-critical patient care workflows. The significance of this research lies in demonstrating the potential of multimedia information to enhance clinical decision-making and streamline the EMS-to-ED handoff process. The study concludes that while CrashHelp is technically viable and clinically useful, future efforts must focus on establishing protocols and procedures to integrate multimedia data seamlessly into standard workflows. Mandatory usage protocols are recommended to better assess clinical value and patient outcomes. Additionally, the authors suggest that further research should explore business models for long-term sustainability and evaluate the system’s impact on traffic clearance operations and overall patient survivability.
Key finding
When used, the CrashHelp multimedia application was perceived by EMS and ED staff as easy to use and helpful for clinical decision-making, but voluntary participation resulted in inconsistent usage that limited overall information utilization.
