Defining emergency telehealth.

The American College of Emergency Physicians Emergency Telehealth Section was charged with development of a working definition of emergency telehealth that aligns with the College's definition of emergency medicine. A modified Delphi method was used by the section membership who represented telehealth providers in both private and public health-care delivery systems, academia and industry, rural and urban settings. Presented in this manuscript is the final definition of emergency telehealth developed with an additional six clarifying statements to address the context of the definition. Emergency telehealth is a core domain of emergency medicine and is inclusive of remotely providing all types of care for acute conditions of any kind requiring expeditious care irrespective of any prior relationship. The development of this definition is important to the global community of emergency physicians and all patients seeking acute care to ensure that appropriately trained clinicians are providing the highest quality of emergency services via the telehealth modality. We recommend implementing emergency telehealth in a manner that ensures appropriate qualifications of providers, appropriate/parity reimbursement for telehealth services and, most importantly, the delivery of quality care to patients in a safe, efficient, timely and cost-effective manner.

Bolus Dose Epinephrine Improves Blood Pressure but is Associated with Increased Mortality in Critical Care Transport.

Objective: Hypotension in the prehospital environment is common and linked to dose-dependent mortality. Bolus dose epinephrine (BDE) may reverse hypotension. We tested if BDE use to treat profound hypotension is associated with 24-hour survival. Methods: We performed a retrospective case-cohort study of critical care transport patients with systolic blood pressure (SBP) <70 mmHg from January 2011 to January 2017. To account for baseline differences between treated and untreated patients, we used nearest neighbor matching to estimate the average treatment effect of BDE on 24-hour survival. Included covariates were age, gender, shock type (cardiogenic, distributive, obstructive or hypovolemic), weight, type of service, vitals (heart rate, SBP and diastolic blood pressure, respiratory rate, oxygen saturation, end-tidal carbon dioxide, and Glasgow Coma Scale score) at the time of the first hypotensive episode, as well as pretreatment characteristics including cardiopulmonary resuscitation, defibrillation, transcutaneous pacing, needle thoracostomy, vasopressors, intubation, or arrhythmias. After statistical analysis, we assessed for residual bias by selecting random matched patient records and asking 2 blinded physicians to rate overall illness severity on a Likert scale. We compared perceived illness severity between cases and matched controls using a rank-sum test. Results: There were 6,992 patients transported with SBP <70 mmHg at least once and 4,374 meet inclusion criteria. Of the 1,620 patients transported after protocol implementation, 574 (35%) received BDE. Overall 24-hour survival, survival to discharge and 30-day survival were 80, 57, and 54%, respectively. Survival at 24 hours differed between the BDE group (66%) and controls (82%). These differences persisted at both discharge and 30 days. Administration of BDE was associated with increased post-treatment SBP. BDE treated patients were also more likely to receive cardiopulmonary resuscitation and vasopressors after treatment than untreated hypotensive patients, but there was no association with tachydysrhythmias requiring defibrillation. Conclusions: Bolus dose epinephrine increases blood pressure in the prehospital setting. Despite robust efforts to control for confounding, BDE remained associated with increased mortality in this observational cohort. This association may be due to unmeasured confounding and a randomized controlled trial is necessary to establish a causal relationship between bolus dose vasopressors and mortality.

The effect of shift length on fatigue and cognitive performance in air medical providers.

OBJECTIVE: To employ a battery of previously validated surveys and neuropsychological tests to compare changes in fatigue and cognitive abilities of air medical providers after 12- and 24-hour shifts. METHODS: A convenience sample of 34 flight nurses and flight paramedics employed by one air medical service completed the Pittsburgh Sleep Quality Index (PSQI) and the Chalder Fatigue Questionnaire (CFQ) to determine fatigue before and after 12-hour (n = 16) and 24-hour (n = 19) shifts. A battery of neuropsychological tests, including the University of Southern California Repeatable Episodic Memory Test (USC-REMT), Paced Auditory Serial Addition Test (PASAT), Trail Making Test (TMT), and Stroop Color-Word Test were administered before and after the shift to measure changes in cognition. We compared the change in scores stratified by shift length using t-tests, Wilcoxon signed-rank test, and Fisher's exact test. RESULTS: Participants in the 12- and 24-hour shift groups were aged 36 ± 8 years (12-hour shifts) and 39 ± 6 years (24-hour shifts) (mean ± standard deviation) and were preponderantly male (62% 12-hour shifts; 63%, 24 hour shifts). The PSQI scores identified 50% of both 12-hour and 24-hour shift subjects as having poor sleep quality. Preshift fatigue was described as a median 2/10 (interquartile range [IQR] = 2-4) and fatigue declined by the end of the shift to a median 1/10 [IQR = 1-2], p = 0.006. Providers averaged 6.8 hours of sleep during 24-hour shifts and 1 hour of sleep during 12-hour shifts. Changes in cognitive scores did not differ between groups. CONCLUSIONS: This study identified no changes in cognitive performance following 12- and 24-hour shifts in air medical providers. This suggests that 24-hour shifts in an air medical service with low to moderate utilization do not have a detrimental effect on cognition as measured by this test battery, and are comparable to 12-hour shifts in terms of impact on cognitive function.

Comparison of three airway management techniques in a simulated tactical setting.

INTRODUCTION: Several different methods for emergent airway management are feasible in the tactical environment. Current studies fail to identify which method minimizes the exposure of the tactical medic or which is most rapid with the greatest chance of first-attempt success. METHODS: We evaluated three commonly used airway management techniques, including standard direct laryngoscopy with endotracheal intubation, digital endotracheal intubation, and use of the King LT laryngotracheal airway device. Study participants were volunteer emergency medicine (EM) residents and medical flight crew members with difficult airway management skills. We compared the times to successful ventilation, numbers of attempts to successful ventilation, and heights of presentation of the participants above a barricade used to simulate concealment. RESULTS: Thirty-one subjects completed the study, of whom 12 (39%) were medical flight crew members and 19 (61%) were EM residents. All subjects were able to successfully ventilate manikins using each of the three methods. The mean number of attempts to intubate and ventilate the manikin was 1.03 for direct laryngoscopy, 1.26 for the King LT, and 1.67 for digital endotracheal intubation. Mean time to ventilation was 59.7 seconds for the King LT, 63.3 seconds for laryngoscopy, and 125.4 seconds for digital intubation. The maximum height the medic reached above the barricade during airway management was 17.7 inches for the King LT, 19.7 inches for laryngoscopy, and 23.5 inches for digital intubation. Comparison of all three factors across groups showed significance, with the exception of time to ventilation between laryngoscopy and use of the King LT. CONCLUSION: In a simulated tactical airway management scenario, use of the King LT provided less exposure than digital or standard endotracheal intubation techniques. Digital intubation behind the simulated barricade was the least successful by all measures. Although direct laryngoscopy was the most successful on the first attempt, use of the King LT in our scenario provided the least exposure of the medic and was as effective as direct laryngoscopy with regard to time to ventilation.
