Vertical flight was sought-after by scientists for centuries, finding early beginnings in children's toys and slowly developing into the modern helicopter. For centuries, true success was elusive, and many machines failed to achieve safe, controlled flight. Despite slow progress, vertical flight enthusiasts were unrelenting and continued trialing new concepts until one finally rose above the rest. As technology advanced, the critical role of helicopters in medical evacuation became apparent. Throughout recent history, continuous progress in vertical flight technology has led to widespread and multifaceted use of helicopters in civilian and military medical operations.

Chest pain is a common complaint for consultation of emergency medical services worldwide. Currently, ambulance nurses (AN) base their decision to transport a patient to the hospital on their own professional experience. The HEART score could improve prehospital risk stratification and patient treatment. The aim of this study is to investigate the interrater reliability and predictive accuracy of the HEART score between AN and emergency physicians (EP). A retrospective analysis on data of 569 patients 18 years and older included in two prehospital HEART score studies. The endpoints are interrater reliability (intraclass correlation [ICC]) and predictive accuracy for major adverse cardiac events within 30 days of the HEART score calculated by AN versus EP. Predictive accuracy is sensitivity, specificity, positive predicted value (PPV) and negative predicted value (NPV). Interrater reliability was good for total HEART score (ICC 0.78; 95% CI 0.75-0.81). However, focusing on the decision to transport a patient, the ICC dropped to 0.62 (95% CI 0.62-0.70). History and Risk factors caused the most variability. Predictive accuracy of HEART differed between AN and EP. The HEART score calculated by AN was sensitivity 91%, specificity 38%, PPV 26%, and NPV 95%. The HEART score calculated by EP was sensitivity 98%, specificity 32%, PPV-26%, and NPV 99%. With a cut-off value of 0-2 for a low HEART score, predictive accuracy significantly improved for the HEART score calculated by AN: sensitivity 98%, specificity 18%, PPV 22%, and NPV 98%. Our study shows a moderate interrater reliability and lower predictive accuracy of a HEART score calculated by AN versus EP. AN underestimate the risk of patients with acute chest pain, with the largest discrepancies in the elements History and Risk factors. Reconsidering the cut-off values of the low-risk HEART category, as well as a carefully developed training program, will possibly lead to a higher interrater reliability of the HEART score and higher predictive accuracy used by AN.

Objective: The aim of this study was to examine the influence of work-related behavior and experience patterns on sleep quality in emergency medical service personnel. Methods: From the total sample of 508 emergency medical service workers who took part in the Germany-wide online survey, 368 respondents completed the questionnaires on sleep characteristics (Pittsburgh Sleep Quality Index [PSQI]) and work-related behavior and experience pattern. Three hundred sixty-seven of the 368 participants also finished the Regensburg Insomnia Scale. Results: Based on their work-related behavior and experience pattern results, individuals were categorized into one of the four following patterns: two risk patterns (A, B) and two healthy behavior and experience patterns (G, S). Participants that were classified into risk-pattern A and B (33.85%) scored significantly higher in both PSQI and Regensburg Insomnia Scale overall score and all PSQI components implicating a poorer sleep quality. A total of 78.5% of the individuals with pattern A and B were considered bad sleepers whereas only 43.4% of individuals with pattern G and S were scored as bad sleepers. Conclusions: Work-related behavior and experience patterns showed a strong association to sleep characteristics and may therefore be used to identify appropriate preventative measures.

Study Design.: Retrospective study. Objective.: The importance of attenuating the cardiovascular autoregulatory disturbances accompanying acute spinal cord injury (SCI) has long been recognized. This report assembles SCI emergency service data and correlates cardiovascular parameters to preserved functional neuroanatomy. Summary of Background Data.: The nascent nature of evidence-based reporting of prehospital cardiovascular autoregulatory disturbances in SCI indicates the need to assemble more information. Materials and Methods.: SCI data for <24 hours were extracted from ambulance and hospital records. The mean arterial pressure (MAP) was calculated. The International Standard for Neurological Classification of SCI (ISNCSCI) evaluates the primary outcome of motor incomplete injury (grades C/D) at acute presentation. Logistic regression was adjusted for multiple confounders that were expected to influence the odds of grade C/D. Results.: A cohort of 99 acute SCI cases was retained; mean (SD) age 40.7±20.5 years, 88 male, 84 tetraplegic, 65 grades A/B (motor complete injury), triage time 2±1.6 hours. The lowest recorded prehospital MAP [mean (SD): 77.9±19, range: 45–145 mm Hg] approached the nadir for adequate organ perfusion. Thirty-four (52%) grade A/B and 10 (30%) C/D cases had MAP readings <85 mm Hg. In data adjusted for age, injury level, and triage time a 5 mm Hg increase in the lowest MAP value was associated with a 34% increase in the odds of having motor incomplete injury at acute presentation (adjusted odds ratio=1.34; 95% CI: 1.11–1.61; P =0.002). Conclusion.: An important observation with implications for timely and selective cardiovascular resuscitation during SCI prehospital care involves significant negative associations between the depth of systemic hypotension and preserved functional neuroanatomy. Regardless of the mechanism, our confounder-adjusted logistic regression model extends in-hospital evidence and provides a conceptual bedside-bench framework for future investigations.

Background: The treatment of supracondylar humerus (SCH) fractures is increasingly centralized in tertiary centers. Interfacility transfer from other facilities may occur by ground ambulance or privately owned vehicle (POV). The objective of this study was to determine if interfacility transfer by POV is equivalent in transfer time and perioperative complications compared with ground ambulance., Methods: This was a single-institution, retrospective study of SCH fractures with an intact pulse transferred by POV or ground ambulance. Transfer time points were collected to determine transfer time and speed. Associated injuries of ipsilateral fracture, skin at risk, and motor nerve palsy were recorded from orthopaedic documentation at the presentation. Insurance status and the Area Deprivation Index (ADI) were used as measures of socioeconomic disparity., Results: 676 "urgent" Type III, IV, and flexion type SCH fractures and 167 "nonurgent" Type II SCH fractures were transferred by ambulance or POV. Open reduction was similar between urgent transfers transported by ambulance or POV (10% vs. 9%, P =0.344). There was no difference in transfer time ( P =0.391) or transfer speed ( P =0.416) between transfer groups. POV transfers were independently associated with no skin at risk (OR 2.1; 95% CI: 1.3-3.3, P =0.003), neurovascularly intact (OR 2.5; 95% CI: 1.4-4.4, P =0.001), and patients in the low (OR 1.9; 95% CI: 1.3-2.5, P =0.041) and moderate deprivation (OR 1.9; 95% CI: 1.1-3.5, P =0.034) compared with the high deprivation group. Medicaid insurance was associated with a lower odds ratio of private transport compared with commercial insurance (OR 0.54; 95% CI: 0.38-0.76, P =<0.001)., Conclusions: Interfacility transfer of nonemergent SCH fractures by privately owned vehicles has a similar speed of transfer and perioperative complication rate to transfer by ground ambulance. Our findings allow the triaging of nonemergent SCH fractures for potential interfacility transfer by privately owned vehicles and bring attention to disparities in interfacility transfer methods., Level of Evidence: Level III- Retrospective cohort study., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background and Objectives: To analyze the ability of prehospital lactate levels to predict 2-day in-hospital mortality in patients with traumatic brain injury (TBI), severe TBI (Glasgow Coma Scale (GCS) ≤ 8 points), and mild or moderate TBI (GCS ≥ 9 points). Second, 90-day mortality was also explored., Methods: This was a prospective, multicenter, emergency medical services (EMSs) delivery, ambulance-based, derivation-validation cohort study developed in 5 tertiary hospitals (Spain), from November 1, 2019, to July 31, 2022. Patients were recruited from among all phone requests for emergency assistance among adults who were later evacuated to referral hospitals with acute TBI. The exclusion criteria were minors, pregnancy, trauma patients without TBI, delayed presentations, patients were discharged in situ, participants with cardiac arrest, and unavailability to obtain a blood sample. The primary outcome was all-cause 2-day in-hospital mortality and 90-day mortality in patients with moderate or mild TBI compared with patients with severe TBI. Clinical and analytical parameters (lactate and glucose) were collected. The discriminative power (area under the receiver operating characteristic curve [AUC]) and calibration curve were calculated for 2 geographically separated cohorts., Results: A total of 509 patients were ultimately included. The median age was 58 years (interquartile range: 43-75), and 167 patients were female (32.8%). The primary outcome occurred in 9 (2.2%) of 415 patients with moderate or mild TBI and in 42 (44.7%) of 94 patients with severe TBI. The predictive capacity of the lactate concentration was globally validated in our cohort, for which the AUC was 0.874 (95% CI 0.805-0.942) for the validation cohort. The ability of the GCS score to predict lactate concentration was greater in patients with a GCS score ≥9 points, with an AUC of 0.925 (95% CI 0.808-1.000) and a negative predictive value of 99.09 (95% CI 98.55-99.64) in the validation cohort., Conclusion: Our results show the benefit of using lactate in all patients with TBI, particularly in those with a GCS ≥9 points. Routine incorporation of lactate in the screening of patients with TBI could presumably reduce mortality and deterioration rates because of quicker and better identification of patients at risk.

The time it takes to begin treatment in life-threatening situations is critical. Ambulance transport to the hospital in such situations ensures quick and effective treatment but is not always readily available in nonurban areas, or not preferred by the public, for various reasons. The purpose of this qualitative study was to examine the factors that deter or encourage ambulance use in life-threatening situations in the geographic periphery from clients' perspectives. We conducted interviews with 71 patients in 3 medical centers who had arrived by ambulance or by private transport, and with the 3 emergency department directors. The findings revealed that awareness of the clinical situation and health literacy, accessibility of emergency services, geographical conditions, and social and economic factors are central in the decision to utilize this service. We detail research recommendations for strengthening public health literacy and access to services. [ABSTRACT FROM AUTHOR]

Digital technology has an essential role in the development and application of innovations within the health care system. Its application is not limited to the hospital environment but extends to the emergency medical services system. The experimental phase of the shift to electronic emergency medical services documentation was performed within the Azienda Sanitaria Universitaria Friuli Centrale of Udine (Italy), a local health authority covering about 533 000 inhabitants. Considering the results of this study, we believe it is important to continue to update the methods of data collection and analysis in correlation with the management and outcomes of the patients.

Background: Early treatment with a potent oral platelet P2Y12 inhibitor is recommended in patients presenting with ST-segment-elevation myocardial infarction scheduled to undergo primary percutaneous coronary intervention (pPCI). The impact on coronary reperfusion of crushed P2Y12 inhibitor tablets, which lead to more prompt and potent platelet inhibition, is unknown.Methods: We conducted a randomized controlled, multicenter trial in the Netherlands, enrolling patients with ST-segment-elevation myocardial infarction scheduled to undergo pPCI. Patients were randomly allocated to receive in the ambulance, before transfer, a 60-mg loading dose of prasugrel either as crushed or integral tablets. The independent primary end points were thrombolysis in myocardial infarction (TIMI) 3 flow in the infarct-related artery at initial coronary angiography, and complete (≥70%) ST-segment resolution 1 hour after pPCI. The safety end points were TIMI major and Bleeding Academic Research Consortium ≥3 bleedings. Secondary end points included platelet reactivity and ischemic outcomes.Results: A total of 727 patients were assigned to either crushed or integral tablets of prasugrel loading dose. The median time from study treatment to wire-crossing during pPCI was 57 (47-70) minutes. The primary end point TIMI 3 flow in the infarct-related artery before pPCI occurred in 31.0% in the crushed group versus 32.7% in the integral group (odds ratio, 0.92 [95% CI, 0.65-1.30], P=0.64). Complete ST-segment resolution 1 hour after pPCI was present in 59.9% in the crushed group versus 57.3% in the integral group (odds ratio, 1.11 [95% CI, 0.78-1.58], P=0.55). Platelet reactivity at the beginning of pPCI, measured as P2Y12 reactivity unit, differed significantly between groups (crushed, 192 [132-245] versus integral, 227 [184-254], P≤0.01). TIMI major and Bleeding Academic Research Consortium ≥3 bleeding occurred in 0% in the crushed group versus 0.8% in the integral group, and in 0.3% in the crushed group versus 1.1% in the integral group, respectively. There were no differences observed between groups regarding ischemic events at 30 days.Conclusions: Prehospital administration of crushed prasugrel tablets does not improve TIMI 3 flow in the infarct-related artery before pPCI or complete ST-segment resolution 1 h after pPCI in patients presenting with ST-segment-elevation myocardial infarction scheduled for pPCI.

The article discusses a Swedish study wherein drones equipped with automated external defibrillators (AEDs) dispatched for suspected out-of-hospital cardiac arrests delivered AEDs before ambulance arrived in two-thirds of cases.

Objective: The aim was to describe the characteristics of the transport system of critically ill pediatric patients in the emergency departments (EDs) in Latin America (LA)., Methodology: This is a prospective cross-sectional study in a 1-year period. Patients were recruited on days 1, 7, 14, 21, and 28 of each month in the EDs in LA. We included ill-pediatric patients aged 1 month to 18 years. Patients who needed transfer for a diagnostic study, with arrival mode not by ambulance, or with the impossibility of interviewing the transfer team were excluded from the study., Results: A total of 389 patients were included in the study. The majority were males (57%) with a median age of 49 months (interquartile range, 10-116). Thirty-three percent (129) of transfers had the participation of a coordinating center; 97.1% (375) were carried out by road ambulance, and 84.3% (323) were interhospital transfers, with a mean distance traveled of 83.2 km (SD, 105 km). The main reason for transfer in 88.17% (343) was the need for a more complex health center. The main diagnosis was respiratory distress (71; 18.2%), acute abdomen (70; 18%), Traumatic Brain Injury (33; 8.48%), multiple trauma (32; 8.23%), septic shock (31; 7.9%), and COVID-19-related illness (19; 4.8%). A total of 296 (76.5%) patients had peripheral vascular access, and 171 (44%) patients had oxygen support with 49 (28.6%) having invasive ventilation; the most frequent monitoring method (67.8%) was pulse oximetry, and 83.4% (313) did not record adverse events. Regarding the transfer team, 88% (342) had no specialized personnel, and only 62.4% (243) had a physician on their teams., Conclusions: In LA, there is great variability in personnel training, equipment for pediatric transport, team composition, and characterization of critical care transport systems. Continued efforts to improve conditions in our countries may help reduce patient morbidity and mortality., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background and Importance: Ensuring prompt ambulance responses is complicated and costly. It is a general conception that short response times save lives, but the actual knowledge is limited., Objective: To examine the association between the response times of ambulances with lights and sirens and 30-day mortality., Design: A registry-based cohort study using data collected from 2014-2018., Settings and Participants: This study included 182 895 individuals who, during 2014-2018, were dispatched 266 265 ambulances in the Capital Region of Denmark., Outcome Measures and Analysis: The primary outcome was 30-day mortality. Subgroup analyses were performed on out-of-hospital cardiac arrests, ambulance response priority subtypes, and caller-reported symptoms of chest pain, dyspnoea, unconsciousness, and traffic accidents. The relation between variables and 30-day mortality was examined with logistic regression., Results: Unadjusted, short response times were associated with higher 30-day mortality rates across unadjusted response time quartiles (0-6.39 min: 9%; 6.40-8.60 min: 7.5%, 8.61-11.80 min: 6.6%, >11.80 min: 5.5%). This inverse relationship was consistent across subgroups, including chest pain, dyspnoea, unconsciousness, and response priority subtypes. For traffic accidents, no significant results were found. In the case of out-of-hospital cardiac arrests, longer response times of up to 10 min correlated with increased 30-day mortality rates (0-6.39 min: 84.1%; 6.40-8.60 min: 86.7%, 8.61-11.8 min: 87.7%, >11.80 min: 85.5%). Multivariable-adjusted logistic regression analysis showed that age, sex, Charlson comorbidity score, and call-related symptoms were associated with 30-day mortality, but response time was not (OR: 1.00 (95% CI [0.99-1.00]))., Conclusion: Longer ambulance response times were not associated with increased mortality, except for out-of-hospital cardiac arrests., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: The Emergency Medical Treatment and Active Labor Act (EMTALA) was enacted in 1986 in the United States to address "patient dumping," or refusing to provide emergency care to patients and instead transferring them to other hospitals. Under EMTALA, the "reverse-dumping" provision prevents hospitals from refusing patients who require specialized capabilities or facilities if the hospital has the capacity to treat them. Despite this provision, patients continue to be transferred to distant tertiary care centers.Methods: We reviewed the literature on EMTALA in the context of a critically ill woman with an infection associated with an orthopaedic implant who was rejected from 2 geographically closer tertiary care centers and was ultimately transferred by helicopter ambulance to an academic teaching hospital that was 169 miles away from her home.Results: After transfer to our tertiary care, level-I trauma center, the patient spent 61 days in the intensive care unit; she required 9 operative procedures, which totaled 1,520 minutes of operative time. Eighteen medical specialties and 8 ancillary medical consulting teams were involved in her care. She underwent 1,436 laboratory and 83 radiographic studies. The total reimbursement from Medi-Cal (California's Medicaid program) for her care in our tertiary care center was $463,753; the hospital charges were more than tenfold higher.Conclusions: Dumping and reverse dumping continue despite compromise of patient care and the high financial burden of the accepting institutions. This may be due to ineffective monitoring and enforcement, lack of uniformity among the courts, and lack of incentive to receive uninsured or poorly funded patients. Under EMTALA, it is difficult for tertiary care centers to argue lack of specialized capabilities or capacity to accept patients, and neither hospitals nor physicians are compensated for the charges of providing care to uninsured or underinsured patients. Moving forward, efforts to better align financial incentives through cost-sharing between community hospitals and tertiary care centers, increased clinician literacy regarding the provisions of EMTALA, and increased transparency with hospital transfers may help improve EMTALA compliance and patient care.

The aim of this study was to explore the relationship between changes in prehospital blood pressure (BP) and the incidence of early neurological deterioration (END) after spontaneous intracerebral hemorrhage (SICH) in patients who arrive at the emergency department (ED) with a normal Glasgow Coma Scale (GCS) score. Records of consecutive adults with SICH transported by ambulance and treated in our ED from January 2015 to December 2017 were retrospectively reviewed. The study cohort included all patients with SICH occurring within the previous 6 hr who had a normal GCS score on ED arrival. Detailed information was retrieved from our hospital's intracerebral hemorrhage databank and then cross-checked in the medical and nursing charts to confirm completeness and accuracy. Early neurological deterioration was defined as a decrease of 2 or more points in the GCS score within 6 hr after ED arrival. The change in prehospital BP was defined as the BP on ED arrival minus the initial on-scene BP. An association between a change in prehospital BP and the occurrence of END was assessed by univariate and multivariate analyses (multiple logistic regression analysis). Of the 168 patients evaluated, 36 (21.4%) developed END. Factors associated with END on univariate analysis were regular antiplatelet agent use, shorter elapsed time, on-scene systolic blood pressure (SBP), prehospital SBP increase of 15 mmHg or more, intraventricular extension of the hematoma, and the presence of 3 or more noncontrast computed tomographic signs of hematoma expansion. After adjusting for other covariates, an increase in prehospital SBP of 15 mmHg or more was significantly associated with a higher risk of END. In patients with SICH who arrive at the ED with a normal GCS score, an increase in the prehospital SBP of more than 15 mmHg is associated with a higher incidence of END. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is available in the text. Background: In out-of-hospital cardiac arrest (OHCA), geographic disparities in outcomes may reflect baseline variations in patients' characteristics but may also result from differences in the number of ambulances providing basic life support (BLS) and advanced life support (ALS). We aimed at assessing the association between allocated ambulance resources and outcomes in OHCA patients in a large urban community. Methods: From May 2011 to January 2016, we analyzed a prospectively collected Utstein database for all OHCA adults. Cases were geocoded according to 19 neighborhoods and the number of BLS (firefighters performing cardiopulmonary resuscitation and applying automated external defibrillator) and ALS ambulances (medicalized team providing advanced care such as drugs and endotracheal intubation) was collected. We assessed the respective associations of Utstein parameters, socioeconomic characteristics, and ambulance resources of these neighborhoods using a mixed-effect model with successful return of spontaneous circulation as the primary end point and survival at hospital discharge as a secondary end point. Results: During the study period, 8754 nontraumatic OHCA occurred in the Greater Paris area. Overall return of spontaneous circulation rate was 3675 of 8754 (41.9%) and survival rate at hospital discharge was 788 of 8754 (9%), ranging from 33% to 51.1% and from 4.4% to 14.5% respectively, according to neighborhoods (P <0.001). Patient and socio-demographic characteristics significantly differed between neighborhoods (P for trend <0.001). After adjustment, a higher density of ambulances was associated with successful return of spontaneous circulation (respectively adjusted odds-ratio [aOR], 1.31 [1.14–1.51]; P <0.001 for ALS ambulances >1.5 per neighborhood and aOR, 1.21 [1.04–1.41]; P =0.01 for BLS ambulances >4 per neighborhood). Regarding survival at discharge, only the number of ALS ambulances >1.5 per neighborhood was significant (aOR, 1.30 [1.06–1.59] P =0.01). Conclusions: In this large urban population-based study of out-of-hospital cardiac arrests patients, we observed that allocated resources of emergency medical service are associated with outcome, suggesting that improving healthcare organization may attenuate disparities in prognosis.

Objectives: Public health and social services spending have been shown to improve health outcomes at the county level, although there are significant state and regional variations in such spending. Texas offers an important opportunity for examining nuances in the patterns of association between local government health and social services spending and population health outcomes. The primary objectives of this study were to describe local investments in education, health, and social services at the county-area level for all of Texas from 2002 through 2012 and to examine how changes in local investment over time were associated with changes in health outcomes.Methods: We used two large secondary data sources for this study. First, US Census Bureau data were used to measure annual spending by all local governments on public hospitals, community health care and public health, and >1 dozen social services. Second, County Health Rankings & Roadmaps data measured county health outcomes. We performed regression models to examine the association between increases in local government spending and a county's health outcomes ranking 4 years later. Multilevel mixed-effects linear regression models accounted for mean spending in each category, county health factors ranking, and county and state random effects.Results: Local governments in Texas spent an average of $4717 per capita across all health and social services. Although spending was relatively consistent across 2002-2012, there was notable variation in spending across counties and services. Regression models found that changes in four spending categories were associated with significant improvements in health outcomes: fire and ambulance, community health care and public health, housing and community development, and libraries. For each, an additional one-time investment of $15 per capita was associated with a 1-spot improvement in statewide county health rankings within 4 years.Conclusions: Existing evidence regarding the association between social services spending and health outcomes may not yield sufficiently granular data for policy makers within a single state. Investments in certain social services in Texas were associated with improvements in health outcomes, as measured by improvements in the County Health Rankings, in the years subsequent to spending increases. Similar analyses in other states and regions may yield actionable avenues for policy makers to improve population health. [ABSTRACT FROM AUTHOR]

This article discusses the implementation of 3 targeted interventions aimed at reducing infection rates in patients due to prolonged in situ intravascular catheters (IVCs) during their admission to the hospital. These IVCs are inserted by paramedics with Queensland Ambulance Service (QAS) in prehospital settings. The 3 interventions involved were the application of "QAS-IVC" stickers by QAS paramedics to indicate QAS-inserted IVCs, the implementation of mandatory IVC documentation during patient handover, and clinician engagement to provide patient education on IVC infection signs. Audits undertaken in wards reflected that the interventions were apparent and beneficial; this is evident from the limited number of patients having in-dwelling QAS-IVC and increased awareness among medical staff and patients alike. We, however, did not have comparative data to objectively quantify the success of the interventions implemented. [ABSTRACT FROM AUTHOR]

Making nonconveyance decisions can be demanding for care providers in prehospital emergency services. Studies have found homecare instructions and counseling of patients and family members partly insufficient. A descriptive cross-sectional design was applied for this pilot study to explore emergency patients' and family members' experiences of nonconveyance situations and counseling. Data were collected by questionnaires from acutely ill patients ( n= 97) treated on-site and not transported to hospital and from their family members ( n= 72) in 2015-2016. Responses to quantified statements were analyzed statistically, whereas responses to open questions were analyzed using qualitative inductive content analysis. Patients and family members had mostly received verbal home care instructions. Just more than 10% of patients found the instructions insufficient for their coping at home. Male patients were slightly more satisfied with counseling than female patients. One-fifth of female patients but only 6% of male patients were dissatisfied with nonconveyance decisions. In family members, the proportion of dissatisfied respondents was 14%. Older patients were more often dissatisfied than younger patients. Although the majority of the respondents were satisfied with the emergency medical services in general, patients suggested that home care instructions, staff competence, and availability of ambulances should be improved and resources and attention given to patients' opinions increased. Family members proposed more careful assessment of conveyance needs, increased resources, and attention given to the patient. The results highlight the importance of developing a more family-centered approach to emergency care. [ABSTRACT FROM AUTHOR]

Objectives: The aims of this study were to identify the pediatric transport methods used by Emergency Medical Services (EMS) personnel in our area and to highlight the need for federal standards to unify prehospital transport of children., Methods: Children and Restraints Study in Emergency Ambulance Transport is a retrospective observational study of EMS arrivals to an academic pediatric emergency department for 1 year. Review of existing security footage from the ambulance entrance focused on the appropriateness of the selected restraints and the correctness of their application. A total of 3034 encounters were adequate for review and were matched to an emergency department encounter. Weight and age were identified from the chart. Patient weight was used in conjunction with video review to assess for the appropriateness of restraint selection., Results: A total of 53.5% (1622) of patients were transported using a weight appropriate device or restraint system. In 77.1% of all cases (2339), the devices or restraint systems were applied incorrectly. The best results were observed for commercial pediatric restraint devices (54.5% secured appropriately) and for convertible car seats (55.5%). Ambulance cot was used alone in 69.35% of all transports despite it being the appropriate choice in just 18.2% of transports., Conclusions: Our findings confirmed that most pediatric patients transported by EMS are not appropriately secured and are at increased injury in a crash and potentially during normal vehicle operation. Opportunity exists for regulators, industry, and leaders in EMS and pediatrics to develop fiscally and operationally prudent techniques and devices to improve the safety of children in ambulances., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Over the past decades, continuous technological advances and the availability of novel therapies have enabled treatment of more acute medical conditions than ever before. Many of these treatments, such as intravenous thrombolysis and mechanical thrombectomy for acute ischemic stroke, are highly time sensitive. This has raised interest in shifting advanced acute care from hospitals to the prehospital setting. Key objectives of advanced prehospital stroke care may include (1) early targeted treatments in the prehospital setting, for example, intravenous thrombolysis for acute stroke, and (2) advanced prehospital diagnostics such as prehospital large vessel occlusion and intracranial hemorrhage detection, to help inform patient triage and potentially reduce subsequent workload in emergency departments. Major challenges that may hamper a swift transition to more advanced prehospital care are related to conducting clinical trials in the prehospital setting to provide sufficient evidence for emergency interventions, as well as ambulance design, infrastructure, emergency medical service personnel training and workload, and cost barriers. Utilizing new technologies such as telemedicine, mobile stroke units and portable diagnostic devices, customized software applications, and smart storage space management may help surmount these challenges and establish efficient, targeted care strategies that are achievable in the prehospital setting. In this article, we delineate the paradigm of shifting advanced stroke care to the prehospital setting and outline future directions in providing evidence-based, patient-centered prehospital care. While we use acute stroke as an illustrative example, these principles are not limited to stroke patients and can be applied to prehospital triage for any time-critical disease., Competing Interests: Disclosures Dr Ospel is a consultant for Nicolab.

Interhospital transport of acute respiratory distress syndrome (ARDS) patients bears transport-associated risks. It is unknown how interhospital extracorporeal membrane oxygenation (ECMO) transfer of COVID-19 patients by mobile ECMO units affects ARDS mortality. We compared the outcome of 94 COVID-19 patients cannulated in primary care hospitals and retrieved by mobile ECMO-teams to that of 84 patients cannulated at five German ECMO centers. Patients were recruited from March 2020 to November 2021. Twenty-six transports were airborne, 68 were land-based. Age, sex, body-mass-index, Simplified Acute Physiology Score (SAPS) II, days invasively ventilated, and P/F-Ratio before ECMO initiation were similar in both groups. Counting only regional transports (≤250 km), mean transport distance was 139.5 km ± 17.7 km for helicopter (duration 52.5 ± 10.6 minutes) and 69.8 km ± 44.1 km for ambulance or mobile intensive care unit (duration 57.6 ± 29.4 minutes). Overall time of vvECMO support (20.4 ± 15.2 ECMO days for transported patients vs. 21.0 ± 20.5 for control, p = 0.83) and days invasively ventilated (27.9 ± 18.1 days vs. 32.6 ± 25.1 days, p = 0.16) were similar. Overall mortality did not differ between transported patients and controls (57/94 [61%] vs. 51/83 [61%], p = 0.43). COVID-19 patients cannulated and retrieved by mobile ECMO-teams have no excess risk compared with patients receiving vvECMO at experienced ECMO centers. Patients with COVID-19-associated ARDS, limited comorbidities, and no contraindication for ECMO should be referred early to local ECMO centers., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © ASAIO 2023.)

Methods: A prospective, multicenter, ambulance-based study of adult patients with an acute illness involving six advanced life support units and 38 basic life support units, referring to five emergency departments in Spain., Results: The primary outcome was long-term mortality with a 1-year follow-up. The compared scores included: National Early Warning Score 2, VitalPAC early warning score, modified rapid emergency medicine score (MREMS), Sepsis-related Organ Failure Assessment, Cardiac Arrest Risk Triage Score, Rapid Acute Physiology Score, and Triage Early Warning Score. Discriminative power [area under the receiver operating characteristic curve (AUC)] and decision curve analysis (DCA) were used to compare the scores. Additionally, a Cox regression and Kaplan-Meier method were used. Between 8 October 2019, and 31 July 2021, a total of 2674 patients were selected. The MREMS presented the highest AUC of 0.77 (95% confidence interval, 0.75-0.79), significantly higher than those of the other EWS. It also exhibited the best performance in the DCA and the highest hazard ratio for 1-year mortality [3.56 (2.94-4.31) for MREMS between 9 and 18 points, and 11.71 (7.21-19.02) for MREMS > 18]., Conclusion: Among seven tested EWS, the use of the MREMS presented better characteristics to predict 1-year mortality; however, all these scores present moderate performances., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Stroke is a leading cause of death and disability among the Korean population. Ischemic stroke patients tend to delay arrival at the hospital and often miss the "golden" 3-hour window, which is optimal for tissue plasminogen activator treatment. Objective: The purposes of this study were to compare demographic, clinical/behavioral, and sociocultural characteristics of ischemic stroke patients who reside in urban and rural areas of Korea and to identify factors contributing to the time taken from symptom onset to hospital arrival. Methods: A cross-sectional, descriptive study was conducted using a structured survey in a convenience sample of 229 ischemic stroke patients in Korea. Results: Individuals who resided in rural areas were more likely to be female, older, less educated; had lower incomes; contacted adult children at the onset of stroke; and took a longer time to be transported to a hospital than did those who resided in urban areas (P < .05). Patients who visited an emergency room, transferred via an ambulance, contacted emergency medical services, perceived symptoms as serious, had a family history of stroke, or experienced hemiparesis as the primary stroke symptom arrived at the hospital relatively sooner, whereas patients who experienced unclear symptoms took relatively more time to arrive at the hospital following symptom onset (P < .05). Conclusions: Nationwide efforts are needed to promote public awareness of stroke and to develop strategies to reduce prehospital delay time for ischemic stroke patients, particularly those who reside in rural areas in Korea.

Objectives: The purpose of the study was to review the impact on survival of trauma victims who were transported via helicopter ambulance versus ground transportation and who received cardiopulmonary resuscitation (CPR) within 1 hour of hospital arrival.Methods: A retrospective analysis of the trauma patients who underwent CPR within 1 hour of arrival to the trauma centers and transported either via air or ground ambulances was performed. Data were extracted from the Research Data Set 2007-2010 from the American College of Surgeons National Trauma Data Bank. Patient and hospital characteristics were compared between the groups. Propensity score matching was performed to balance the baseline characteristics and absolute risk reduction was calculated using the McNemar test to evaluate the risk difference of survival at discharge with the mode of transportation.Results: A total of 1269 patients qualified for the final analysis; 314 patients were transported by helicopter and 955 by ground ambulances. There were significant differences in baseline characteristics between the groups regarding age (P = 0.015), Injury Severity Score (P < 0.001), Glasgow Coma Scale (P < 0.001), male sex (P < 0.001), race (P < 0.001), and injury type (blunt vs penetrating, P < 0.001). After propensity score matching, no significant differences were seen on baseline characteristics between the groups. The mean standardized difference was <10% between the groups after matching in all covariates. There was a higher rate of survival of patients who were brought in via helicopter ambulance (absolute risk reduction 0.066, confidence interval 0.008-0.125, P = 0.02).Conclusions: Higher survival was seen in patients who were transported by helicopter ambulance and received CPR within 1 hour of hospital arrival.

Background: Treatment of patients with acute ischemic stroke on mobile stroke units (MSUs) improves outcomes compared with management by standard emergency medical services ambulances and is associated with more patients treated with intravenous tPA (tissue-type plasminogen activator) in the first golden hour after last known normal. We explored the predictors and outcomes of first-hour treatment (FHT) compared with later treatment in an alternating-week cluster-controlled trial of MSUs., Methods: We analyzed all patients treated with intravenous tPA in the BEST-MSU Study (Benefits of Stroke Treatment Delivered by a Mobile Stroke Unit Compared to Standard Management by Emergency Medical Services). After stratifying by treatment timeframe, we identified factors associated with FHT. We performed adjusted analyses of the association between FHT and clinical outcome and modeled the shape of the relationship between last known normal-to-treatment time and excellent outcome., Results: Among 941 tPA-treated patients, 206 (21.8%) had lytic started within 60 minutes. Treatment on the MSU, older age, male sex, alert by 911, faster arrival on-scene and imaging, more severe stroke, atrial fibrillation, and absence of heart failure and pretreatment antihypertensive treatment were associated with FHT. Compared with later treatment, FHT was associated with higher adjusted odds ratio for 90-day modified Rankin Scale score of 0 to 1 (odds ratio, 1.87 [95% CI, 1.25-2.84]; P =0.003). Among FHT patients, 68% achieved a 90-day modified Rankin Scale of 0 or 1 or returned to their baseline status. FHT was not associated with higher risk of hemorrhage and was associated with reduced risk of treating neurovascular mimics., Conclusions: FHT almost doubles the odds of excellent clinical outcome without increased risk compared with later treatment, which supports the use of MSUs.

Objective: To compare head and trunk acceleration during transport on 2 medical utility vehicles. Design: Within subject. Setting: Controlled laboratory. Participants: Nineteen male volunteers (21.8 ± 1.4 years, 176.5 ± 5.5 cm, 90.3 ± 16.1 kg). Interventions: Participants were secured to a spineboard and stretcher on the Husqvarna HUV 4421DXL ambulance (HUV) and modified John Deere Gator TH (Gator) and driven over synthetic field turf transitioning to concrete slab (interval 1) and concrete slab transitioning to natural grass (interval 2). Three-dimensional (x, y, and z) accelerometers recorded head and trunk acceleration. At each data point, acceleration of the trunk was subtracted from the acceleration of the head and the peak acceleration difference was determined. Independent variables were vehicle (HUV, Gator) and interval (interval 1, interval 2). Main Outcome Measures: The average peak acceleration differences in 3 directions (x, y, z) were analyzed using a 2-factor within analysis of variance (P ≤ 0.05). Results: Forx, Gator in interval 2 (28.34 ± 7.45 m/s/s) was greater than HUV in interval 2 (21.87 ± 6.28 m/s/s), and HUV (11.05 ± 3.29 m/s/s) and Gator (12.56 ± 4.32 m/s/s) in interval 1. The HUV in interval 2 was greater than HUV and Gator in interval 1. For z, Gator in interval 2 (22.12 ± 4.8 m/s/s) was greater than HUV in interval 2 (15.21 ± 2.84 m/s/s), and HUV (9.51 ± 3.01 m/s/s) and Gator (12.5 ± 3.78 m/s/s) in interval 1. The HUV in interval 2 was greater than HUV and Gator in interval 1. Gator in interval 1 was greater than HUV in interval 1. Conclusions: Varying head and trunk accelerations exist in healthy spine-boarded participants during transport on medical utility vehicles dependent on surface and vehicle type. Clinical Relevance: Intermediate transport vehicles vary in their ability to mitigate perturbations conveyed to the patient from the terrain travelled over. [ABSTRACT FROM AUTHOR]

To measure the effect of quality improvement interventions, it is appropriate to use analysis methods that measure data over time. Examples of such methods include statistical process control analysis and interrupted time series with segmented regression analysis. This article compares the use of statistical process control analysis and interrupted time series with segmented regression analysis for evaluating the longitudinal effects of quality improvement interventions, using an example study on an evaluation of a computerized decision support system.

Background and Objective: Stroke reperfusion therapy is time critical. Improving prehospital diagnostic accuracy including the likelihood of large vessel occlusion can aid with efficient and appropriate diversion decisions to optimize onset-to-treatment time. In this study, we investigated whether prehospital telestroke improves diagnostic accuracy when compared with paramedic assessments and assessed feasibility., Methods: We conducted a pragmatic, community-based, cluster randomized controlled trial comparing the diagnostic accuracy of telestroke assessments inside the ambulance with a modified Los Angeles Motor Scale (PASTA score). The primary outcome was the accuracy of predicting reperfusion candidates; secondary outcomes were accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of either approach to identify IV thrombolysis (IVT) and endovascular thrombectomy (EVT) candidates and true stroke patients by study group. The accuracy of telestroke and PASTA assessments was compared against in-person assessment in the emergency department and with the final diagnosis/intervention for the patient. We also monitored for technical challenges., Results: We recruited 76 patients (35 telestroke and 41 PASTA) between August 2019 and September 2020. The mean age was 72.2 (±14.6) years. Telestroke was 100% (95% CI 90%-100%) and PASTA 70.7% (54.5%-83.9%) accurate in predicting reperfusion candidates compared with preimaging emergency department neurologist assessment ( p < 0.001). When compared with actual reperfusion therapy administered, the predictive accuracy was 80% (63.1%-91.6%) and 60.1% (44.5%-75.8%) for telestroke and PASTA, respectively ( p < 0.001). In predicting the administration of IVT, telestroke was 80% (63.1-91.6) and PASTA was 56.1% (39.8-71.5) accurate ( p < 0.001). In predicting intervention with EVT, telestroke was 88.6% (73.3-96.8) and PASTA 56.1% (39.8-71.5) accurate ( p = 0.005). The service model proved technically feasible and was acceptable to neurologists., Discussion: Prehospital telestroke assessment is feasible, accurate, and superior to the PASTA score in predicting acute reperfusion therapies, presenting an effective option to guide prehospital diversion decisions., Trial Registration: The trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12619001678189).anzctr.org.au/Trial/Registration/TrialReview.aspx?id=378655&isReview=true., Classification of Evidence: This study provides Class I evidence that intra-ambulance telestroke evaluation has a greater diagnostic accuracy compared with the PASTA score performed by paramedics in distinguishing hyperacute stroke patients who are candidates for reperfusion therapy., (© 2022 American Academy of Neurology.)

Aim This study aims to identify the processes and frameworks that support an evidence-based approach to clinical policy decision-making practices in ambulance services. Methods This literature review focused on: (i) the setting (pre-hospital); and (ii) the process of evidence translation, for studies published after the year 2000. Searches of Medline, CINAHL and Google were undertaken. Reference lists of eligible publications were searched for relevant articles. Results A total of 954 articles were identified. Of these, 20 full text articles were assessed for eligibility and seven full text articles met the inclusion criteria. Three provided detailed descriptions of the evidence-based practice processes used to inform ambulance service protocol or guideline development or review. Conclusions There is little published literature that describes the processes involved, and frameworks required, to inform clinical policy decision making within ambulance services. This review found that processes were iterative and involved collaborations across many internal and external stakeholders. In several jurisdictions, these were coordinated by a dedicated team. Success appears dependent on committed leadership and purposive human and structural resources. Although time consuming, structured processes have been developed in some jurisdictions to assist decision-making processes. Further insight is likely to be obtained from literature published by those from other disciplines. [ABSTRACT FROM AUTHOR]

This study examines the individual and sociocultural factors related to severity of injury among emergency department (ED) patients across six countries (United States, Canada, Mexico, Australia, Spain, and Italy). Secondary analysis of existing data using probability samples of injured patients from 15 studies (N = 9,599) were analyzed for severity of injury as measured by arrival by ambulance and admission to the hospital, using logistic regression models and multilevel hierarchical linear models. Patients drinking greater quantities of alcohol before the injury were more likely to have arrived to the ED by ambulance or admitted to the hospital after the injury event. Country-level detrimental drinking pattern explained some of the study variation for patients arriving by ambulance but not for patients admitted to the ED. Findings support a relationship between acute alcohol consumption to injury severity; however, further examination of the clinical implications related to triage, patient evaluation, and intervention for alcohol-related problems is merited.

Objectives: Quality standards for pediatric intensive care transport services in the U.K. state that at least one parent should be allowed to travel with their child during emergency transport to a PICU. We aimed to identify the reasons why parents do, or do not, accompany their child and whether there is an association between parental presence in the ambulance and their satisfaction with the transport., Design: National cross-sectional parent questionnaire., Setting: Pediatric Critical Care Transport (PCCT) teams and PICUs in England and Wales., Participants: Parents of children transferred to one of 24 participating PICUs between January 2018 and January 2019., Interventions: None., Measurements and Main Results: A parent feedback questionnaire was completed by parents whose child received an emergency interhospital transfer. As part of the questionnaire, a brief nine-item scale was developed to summarize parental transport experience (ranging from 1 to 5). The association between parental presence in the ambulance and parental experience was analyzed. A total of 4,558 children were transported during the study. Consent was obtained from 2,838 parents, and questionnaires received in 2,084 unique transports (response rate: 45.7%). In 1,563 transports (75%), at least one parent traveled in the ambulance. Parents did not travel in 478 transports (23%) and, in most instances (442 transports; 93%), offered reasons (emotional, practical, and health-related) for declining to travel or explanations why they were not permitted to travel (mainly due to space restrictions). Most parents rated their experience with the retrieval teams very highly, and within this context, we found evidence of greater variability in experience ratings if parents were not present in the ambulance and if this was not their choice., Conclusions: Most parents who completed questionnaires rated their experience with their PCCT team highly. Parental presence and choice to travel in the ambulance were associated with a more positive experience., Competing Interests: Drs.

Objective: Telephone triage service in emergency care has been introduced in many countries, and it is important to determine the effect of telephone triage service on the outcome of emergency patients. The aim of this study was to evaluate the effect of telephone triage service on the outcome of emergency patients using propensity score., Methods Design, Settings, and Participants: This was a retrospective study with a study period from January 2016 to December 2019. We included all patients transported by ambulances of the Osaka Municipal Fire Department during study period., Exposure: Telephone triage service., Outcome Measures and Analysis: The main outcome of this study was unfavorable outcome following use of the telephone triage service. In this study, unfavorable outcome was defined as patients who were admitted, transferred, or died after care in the emergency department. Propensity scores were calculated using a logistic regression model with 12 variables that were present before the telephone triage service was used or were indicative of the patient's condition. Data analyses were not only propensity score matching but also a multivariable logistic regression model and regression model with propensity score as a covariate., Main Results: The number of patients eligible for analyses was 707 474. Of these patients, 8008 (1.0%) used the telephone triage services and 699 466 patients (99.0%) did not use it. The number of patients with an unfavorable outcome was 407 568 (57.6%) in the total cohort. Of them, 2305 patients (28.8%) used the telephone triage service and 297 601 patients (42.5%) did not use it. For propensity score matching, 8008 patients were matched from each group. Use of the telephone triage service was inversely associated with unfavorable outcome in a multivariate logistic regression model with propensity score as a covariate [adjusted odds ratio (OR) 0.874; 95% confidence interval (CI), 0.831-0.919] and propensity score matching (crude OR, 0.875; 95% CI, 0.818-0.936)., Conclusions: This study revealed that the use of the telephone triage service in Osaka city, Japan was associated with better outcomes of patients transported by ambulance., (Copyright © 2022 The Author(s).

The article presents a study on the role of primary percutaneous coronary intervention (PCI) in the improvement of ST-segment elevation resolution (STR). The study involved patients with acute segment elevation myocardial infarction (STEMI) who received abciximab in the ambulance or in the catheterization laboratory. Although the flow rate of STR or TIMI did not improve from the administration of abciximab in STEMI, the TIMI flow pre-PCI and decreased distal embolization tended to improve.

Mobile stroke units (MSUs) are specialized ambulances equipped with the personnel, equipment, and imaging capability to diagnose and treat acute stroke in the prehospital setting. Over the past decade, MSUs have proliferated throughout the world, particularly in European and US cities, culminating in the formation of an international consortium. Randomized trials have demonstrated that MSUs increase stroke thrombolysis rates and reduce onset-to-treatment times but until recently it was uncertain if these advantages would translate into better patient outcomes. In 2021, 2 pivotal, large, controlled clinical trials, B&#95;PROUD and BEST-MSU, demonstrated that as compared with conventional emergency care, treatment aboard MSUs was safe and led to improved functional outcomes in patients with stroke. Further, the observed benefit of MSUs appeared to be primarily driven by the higher frequency of ultra-early thrombolysis within the golden hour. Nevertheless, questions remain regarding the cost-effectiveness of MSUs, their utility in nonurban settings, and optimal infrastructure. In addition, in much of the world, MSUs are currently not reimbursed by insurers nor accepted as standard care by regulatory bodies. As MSUs are now established as one of the few proven acute stroke interventions with an effect size that is comparable to that of intravenous thrombolysis and stroke units, stroke leaders and organizations should work with emergency medical services, governments, and community stakeholders to determine how MSUs might benefit individual communities, and their optimal organization and financing. Future research to explore the effect of MSUs on intracranial hemorrhage and thrombectomy outcomes, cost-effectiveness, and novel models including the use of rendezvous transports, helicopters, and advanced neuroimaging is ongoing. Recommended next steps for MSUs include reimbursement by insurers, integration with ambulance networks, recognition by program accreditors, and inclusion in registries that monitor care quality.

Objective: The aim of this study was to identify work-related experience and behavior patterns among rescue workers in different urban and rural organizational structures., Methods: The subjects included 276 paramedics from Germany (average age 39.3 ± 8.04 years) in three groups (professional fire department, aid organization in urban or rural regions). Work-related behavior and experience patterns (AVEM) were examined. Influences of age, gender, professional qualifications, frequency of operation, and organization were analyzed., Results: AVEM risk patterns were detectable in 44.3% of professional fire department personnel and in 20% of both aid organization groups. There were differences in the various AVEM dimensions. Age had a strong influence on the AVEM dimension work-related ambition., Conclusions: There is a need for workplace health promotion and prevention measures, which are especially useful for employees in professional fire departments. Aid organizations in urban and rural regions should also attend to these measures., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 American College of Occupational and Environmental Medicine.)

Abstract: The emergency medical system, one of the essential elements of public health, has been around for more than 50 years. Although many studies have assessed the factors associated with overcrowding and prolonged length of stay in emergency departments, whether the clinical characteristics and background of a patient are associated with prolonged hospitalization among patients transported by ambulance is unknown. The purpose of this study was to reveal factors associated with the continuation of hospitalization at 21 days after hospital admission among patients transported by ambulance using a population-based patient registry in Osaka, Japan.This was a retrospective observational study whose study period was the three years from January 2016 to December 2018. In this study, we included patients who were hospitalized after transportation by ambulance in Osaka, Japan. The main outcome was continuation of hospitalization at 21 days after hospital admission. We calculated the adjusted odds ratios (AOR) and 95% confidence interval (CI) with a multivariable logistic regression model to assess factors associated with the outcome.We included 481,886 patients in this study, of whom 158,551 remained hospitalized at 21 days after hospital admission and 323,335 had been discharged home by 21 days after hospital admission. Factors associated with prolonged hospitalization were elderly (AOR: 1.767 [95% CI: 1.730-1.805]), traffic accident (AOR: 1.231 [95% CI: 1.183-1.282]), no fixed address (AOR: 4.494 [95% CI: 3.632-5.314]), need for nursing care (AOR: 1.420 [95% CI: 1.397-1.443]) and solitary person (AOR: 1.085 [95% CI: 1.050-1.120]).In this study, the elderly, traffic accidents, no fixed address, need for nursing care, and solitary person were associated with prolonged hospitalization of patients transported by ambulance in Japan., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).

Background and Purpose: Mobile stroke units (MSUs) improve reperfusion therapy times in acute ischemic stroke (AIS). However, prehospital management options for intracerebral hemorrhage (ICH) are less established. We describe the initial Melbourne MSU experience in ICH., Methods: Consecutive patients with ICH and AIS treated by the Melbourne MSU were included. We describe demographics, proportions of patients receiving specific therapies, and bypass to comprehensive/neurosurgical centers. We also compare operational time metrics between patients with MSU-ICH and MSU-AIS., Results: During a 2-year period, the Melbourne MSU managed 49 patients with ICH, mean (SD) age 74 (12) years, median (interquartile range) National Institutes of Health Stroke Scale 17 (12–20). Intravenous antihypertensives were the commonest treatment provided (46.9%). Bypass of a primary center to a comprehensive center with neurosurgical expertise occurred in 32.7% of patients with MSU-ICH compared with 20.5% of patients with MSU-AIS. Compared with patients with MSU-AIS, patients with MSU-ICH had faster onset-to-emergency-call, and onset-to-scene-arrival times at the median and 75th percentiles., Conclusions: MSUs can facilitate ultra-early ICH diagnosis, management, and triage.
