Comparative StudyIdentification of dynamic prehospital changes with continuous vital signs acquisition.
In most trauma registries, prehospital trauma data are often missing or unreliable because of the difficult dual task consigned to prehospital providers of recording vital signs and simultaneously resuscitating patients. The purpose of this study was to test the hypothesis that the analysis of continuous vital signs acquired automatically, without prehospital provider input, improves vital signs data quality, captures more extreme values that might be missed with conventional human data recording, and changes Trauma Injury Severity Scores compared with retrospectively compiled prehospital trauma registry data. ⋯ Real-time continuous vital signs monitoring and data acquisition can identify dynamic prehospital changes, which may be missed compared with vital signs recorded manually during distinct prehospital intervals. In the future, the use of automated vital signs trending may improve the quality of data reported for inclusion in trauma registries. These data may be used to develop improved triage algorithms aimed at optimizing resource use and enhancing patient outcomes.

Assessing satisfaction and quality in the EMS/HEMS working relationship.
Treatment provided to critically ill and injured patients during air medical transport bridges initial local emergency medical service (EMS) treatment and the care provided upon arrival to the emergency department. Transition of care from EMS to air medical service includes multiple elements, many of which have been previously undefined. These include operational details surrounding the handoff and attention to issues of continuity in patient care. The purpose of this study is to pilot the development of survey instrumentation to measure key elements of quality in the interaction between EMS and air medical crews. ⋯ Using qualitative and quantitative approaches, a survey instrument was developed to assess satisfaction with HEMS care from the EMS provider's perspective. Evaluating the EMS perspective on the working relationship with HEMS is a new field of discovery for the air medical transport industry and process improvement activities.

Activation intervals for a helicopter emergency medical service in Japan.
Prehospital time is crucial for treating acute disease; therefore, it is important to activate helicopter emergency medical services (HEMS) promptly. We investigated the differences in the activation intervals (the time elapsed from receiving the emergency call to the time of HEMS request) under various conditions to evaluate the current status of HEMS-related prehospital triage in Japan. ⋯ Endogenous conditions had longer activation intervals, which may reflect a lack of mechanisms assessing their severity. We are considering developing new triage criteria for dispatchers.

An investigation of pilot fatigue in helicopter emergency medical services.
Pilot error has caused the majority of helicopter emergency medical services (HEMS) accidents in the United States for almost 2 decades. Pilot fatigue may have contributed to some of these accidents. This nonexperimental quantitative study investigated the relationships between fatigue reported by on-duty HEMS pilots (the criterion variable) and consecutive HEMS pilot day shifts, consecutive HEMS pilot night shifts, age, and experience as an HEMS pilot (the predictor variables). ⋯ Multivariate regression analysis suggested that experience as an HEMS pilot predicted HEMS pilot night shift respondent BFI scores. Additional quantitative research is recommended to confirm the results of this study and to investigate relationships between fatigue experienced by HEMS pilots and other variables that were not considered in this investigation. Qualitative research to identify and document fatigue management strategies that are used by experience HEMS pilots is also recommended.
