Acute effect of the COVID-19 pandemic on emergency transportation due to acute alcoholic intoxication: a retrospective observational study.

BACKGROUND: The COVID-19 pandemic has caused changes in people's drinking habits and the emergency management system for various diseases. However, no studies have investigated the pandemic's impact on emergency transportation for acute alcoholic intoxication. This study examines the effect of the pandemic on emergency transportation due to acute alcoholic intoxication in Kochi Prefecture, Japan, a region with high alcohol consumption. METHODS: A retrospective observational study was conducted using data of 180,747 patients from the Kochi-Iryo-Net database, Kochi Prefecture's emergency medical and wide-area disaster information system. Chi-squared tests and multiple logistic regression analyses were performed. The association between emergency transportation and alcoholic intoxication was examined. The differences between the number of transportations during the voluntary isolation period in Japan (March and April 2020) and the same period for 2016-2019 were measured. RESULTS: In 2020, emergency transportations due to acute alcoholic intoxication declined by 0.2%, compared with previous years. Emergency transportation due to acute alcoholic intoxication decreased significantly between March and April 2020, compared with the same period in 2016-2019, even after adjusting for confounding factors (adjusted odds ratio 0.67; 95% confidence interval 0.47-0.96). CONCLUSIONS: This study showed that lifestyle changes due to the COVID-19 pandemic affected the number of emergency transportations; in particular, those due to acute alcoholic intoxication decreased significantly.

Complications Associated With the Anesthesia Transport of Pediatric Patients: An Analysis of the Wake Up Safe Database.

BACKGROUND: Transporting patients under anesthesia care incurs numerous potential risks, especially for those with critical illness. The purpose of this study is to identify and report all pediatric anesthesia transport-associated adverse events from a preexisting database of perioperative adverse events. METHODS: An extract of the Wake Up Safe database was obtained on December 14, 2017, and screened for anesthesia transport-associated complications. This was defined as events occurring during or immediately after transport or movement of a pediatric patient during or in proximity to their care by anesthesiologists, including repositioning and transfer to recovery or an inpatient unit, if the cause was noted to be associated with anesthesia or handover. Events were excluded if the narrative clearly states that an event was ongoing and not impacted by anesthesia transport, such as a patient who develops cardiac arrest that then requires emergent transfer to the operating room. The search methodology included specific existing data elements that indicate transport of the patient, handover or intensive care status preoperatively as well as a free-text search of the narrative for fragments of words indicating movement. Screened events were reviewed by 3 anesthesiologists for inclusion, and all data elements were extracted for analysis. RESULTS: Of 2971 events in the database extract, 63.8% met screening criteria and 5.0% (148 events) were related to transport. Events were primarily respiratory in nature. Nearly 40% of all reported events occurred in infants age ≤6 months. A total of 59.7% of events were at least somewhat preventable and 36.4% were associated with patient harm, usually temporary. Of the 86 reported cardiac arrests, 50 (58.1%) had respiratory causes, of which 74% related to anesthesia or perioperative team factors. Respiratory events occurred at all stages of care, with 21.4% during preoperative transport and 75.5% postoperatively. Ninety-three percent of unplanned extubations occurred in patients 6 months and younger. Ten medication events were noted, 2 of which resulted in cardiac arrest. Root causes in all events related primarily to provider and patient factors, with occasional references to verbal miscommunication. CONCLUSIONS: Five percent of reported pediatric anesthesia adverse events are associated with transport. Learning points highlight the risk of emergence from anesthesia during transport to recovery or intensive care unit (ICU). ICU patients undergoing anesthesia transport face risks relating to transitions in providers, equipment, sedation, and physical positioning. Sedation and neuromuscular blockade may be necessary for transport in some patients but has been associated with adverse events in others.

Who receives naloxone from emergency medical services? Characteristics of calls and recent trends.

Background: With the rapid rise in opioid overdose-related deaths, state policy makers have expanded policies to increase the use of naloxone by emergency medical services (EMS). However, little is known about changes in EMS naloxone administration in the context of continued worsening of the opioid crisis and efforts to increase use of naloxone. This study examines trends in patient demographics and EMS response characteristics over time and by county urbanicity. Methods: We used data from the 2013-2016 National EMS Information System to examine trends in patient demographics and EMS response characteristics for 911-initiated incidents that resulted in EMS naloxone administration. We also assessed temporal, regional, and urban-rural variation in per capita rates of EMS naloxone administrations compared with per capita rates of opioid-related overdose deaths. Results: From 2013 to 2016, naloxone administrations increasingly involved young adults and occurred in public settings. Particularly in urban counties, there were modest but significant increases in the percentage of individuals who refused subsequent treatment, were treated and released, and received multiple administrations of naloxone before and after arrival of EMS personnel. Over the 4-year period, EMS naloxone administrations per capita increased at a faster rate than opioid-related overdose deaths across urban, suburban, and rural counties. Although national rates of naloxone administration were consistently higher in suburban counties, these trends varied across U.S. Census Regions, with the highest rates of suburban administration occurring in the South. Conclusions: Naloxone administration rates increased more quickly than opioid deaths across all levels of county urbanicity, but increases in the percentage of individuals requiring multiple doses and refusing subsequent care require further attention.

Medevac Utilization and Patient Characteristics in Rural Alaska 2010 to 2018.

OBJECTIVE: Little is known about medevac utilization in remote, rural Alaska where there is no road access and communities are reliant on medevacs for emergency care. With high financial costs and risks to flight crews, there is an urgent need to understand medevac utilization in rural Alaska. This article aimed to describe medevac utilization and patient characteristics over 9 years in the remote, air transport dependent in Alaska. METHODS: Deidentified data (2010-2018) were obtained for all medevacs originating within the Yukon-Kuskokwim Delta. Descriptive statistics were calculated, and chi-square tests of independence were conducted to identify differences. RESULTS: Four thousand nine hundred ninety-one medevacs were performed, averaging 555 (standard deviation = 67.7) per year. Medevacs for respiratory complaints were predominant for children, whereas trauma predominated for adults 18 to 40 years old. Traumatic injury was more common in males than females aged < 65 years but was more common in females than males aged ≥ 65 years. Significant variability occurred in medevacs based on the community and the hour of the day. CONCLUSION: Medevacs are a critical part of health care in rural, remote Alaska but appear subject to clinical and nonclinical determinants. These baseline data provide a foundation for future studies aiming to increase medevac safety and provide decision-making support.

Does a Mobile ECLS Program Reduce Mortality for Patients Transported for ECLS Therapy for Severe Acute Respiratory Failure?

OBJECTIVE: To understand if mobile extracorporeal membrane oxygenation reduces patient mortality during and after transport of patients requiring extracorporeal membrane oxygenation for acute respiratory distress syndrome. DESIGN: Retrospective chart review. SETTING: University affiliated tertiary care hospitals. PARTICIPANTS: Seventy-seven patients. INTERVENTIONS: Introduction of a mobile extracorporeal membrane oxygenation (ECMO) program designed to facilitate the implementation of ECMO at outside hospitals in patients too unstable for transport for ECMO. MEASUREMENTS AND MAIN RESULTS: The 28-day in-hospital mortality was significantly lower in the post-mobile group (12/51 [23.5%] v 12/24 [50%], adjusted risk difference: 28.6%, [95% CI 4.7-52.5, p = 0.011]). CONCLUSIONS: These findings suggest that patients with severe acute respiratory failure who require transport to a referral center for extracorporeal life support may benefit from the availability of a mobile extracorporeal life support team.

The 8-Year Experience of the Florence Referral ECMO Center and Retrieval Team for Acute Respiratory Failure.

OBJECTIVE: Many extracorporeal membrane oxygenation (ECMO) centers for respiratory failure and ECMO mobile teams were instituted during the H1N1 pandemic. Data on transportation are scarce and heterogeneous. The authors therefore described the experience of their referral ECMO center for severe respiratory failure from 2009 to 2016 and gave a comprehensive report of transfers performed by their mobile ECMO team. DESIGN: Observational retrospective study. SETTING: An intensive care unit (ECMO referral center) in a teaching hospital. PARTICIPANTS: One hundred and sixty consecutive patients with acute respiratory distress syndrome refractory to conventional treatment requiring veno-venous (VV)-ECMO. INTERVENTION: VV-ECMO implantation. MEASUREMENTS AND MAIN RESULTS: In this series, the transferred patients on ECMO averaged 57%, with annual percentages ranging from 28% to 90% over the years. No adverse event was observed during transportation. A progressive increase in simplified acute physiology score (SAPS) values and in the use of norepinephrine were detectable (p = 0.048 and p = 0.037, respectively) as well as in neuromuscular blockers use (p = 0.004). Dual-lumen cannule were more frequently used in recent years (p < 0.001). The overall mortality rate was 40% (64/160), with no differences over the years or between transferred and local patients. Body mass index and pre-ECMO neuromuscular blockers and SAPS were independent predictors for early mortality (when adjusted for age). CONCLUSIONS: The workload of the authors' referral center and mobile team did not change, documenting that severe respiratory failure requiring VV-ECMO support is still a clinical need. No difference in mortality rate was detectable during this period or between transferred and local patients who were managed by the same team.

Prospective use of unmanned aerial vehicles for military medical evacuation in future conflicts.

In order to continue to deliver outstanding medical care on the battlefield, the UK Defence Medical Services must continue to adapt, overcome and actively embrace change. One potential area is the rapid proliferation and sophistication of automated and remote systems such as unmanned aerial vehicles (UAVs). UAVs are already used to deliver blood to remote military locations in Afghanistan and defibrillators to those that need them in the USA and Sweden. An area of future opportunity would be to facilitate rapid evacuation of wounded personnel from high intensity, high threat, remote and austere areas directly to specialist care. Such a capability would reduce threat to human life while allowing rapid extraction of casualties from high risk or inaccessible environments straight back to Role 3 care, all of which in these situations is either not possible or carries too much risk using conventional aerial assets. The article aims to highlight a potential future capability, stimulate debate and reflection, all of which is essential for innovation and future organisational development. The potential uses and benefits of UAVs are highlighted including both the challenges and rewards of utilising UAVs for casualty evacuation. Key benefits are reduced risk to human life, cost, ability to insert into areas conventional aircraft cannot and the rapidity of transfer. Challenges are likely to be airspace management, decisions on appropriate level of care to deliver during transit and ultimately user acceptability. The article also highlights that in order to maximise our ability to exploit new technologies, all arms and trades within the military must be involved in collective research and development. Furthermore, sensible corroboration with private companies will further enhance our ability to acquire products that best serve our needs.

Effect of a mass media campaign on ambulance use for chest pain.

OBJECTIVES: To evaluate the impact of comprehensive public awareness campaigns by the National Heart Foundation of Australia on emergency medical service (EMS) use by people with chest pain. DESIGN, SETTING AND PARTICIPANTS: A retrospective analysis of 253428 emergency ambulance attendances for non-traumatic chest pain in Melbourne, January 2008 - December 2013. Time series analyses, adjusted for underlying trend and seasonal effects, assessed the impact of mass media campaigns on EMS use. MAIN OUTCOME MEASURE: Monthly ambulance attendances. RESULTS: The median number of monthly ambulance attendances for chest pain was 3609 (IQR, 3011-3891), but was higher in campaign months than in non-campaign months (3880 v 3234, P<0.001). After adjustments, campaign activity was associated with a 10.7% increase (95% CI, 6.5-14.9%; P<0.001) in monthly ambulance use for chest pain, and a 15.4% increase (95% CI, 10.1-20.9%; P<0.001) when the two-month lag periods were included. Clinical presentations for suspected acute coronary syndromes, as determined by paramedics, increased by 11.3% (95% CI, 6.9-15.9%; P<0.001) during campaigns. Although the number of patients transported to hospital by ambulance increased by 10.0% (95% CI, 6.1-14.2%; P<0.001) during campaign months, the number of patients not transported to hospital also increased, by 13.9% (95% CI, 8.3-19.8%; P<0.001). CONCLUSION: A public awareness campaign about responding to prodromal acute myocardial infarction symptoms was associated with an increase in EMS use by people with chest pain and suspected acute coronary syndromes. Campaign activity may also lead to increased EMS use in low risk populations.

Acceptability of Alternatives to Traditional Emergency Care: Patient Characteristics, Alternate Transport Modes, and Alternate Destinations.

To determine the acceptability of alternatives to traditional emergency care, we assessed the proportion of subjects willing to consider alternative modes of transportation and alternative destinations. We further identified patient characteristics associated with willingness to consider these alternatives. We conducted a cross-sectional survey study in the emergency department (ED) of an academic medical center. Research assistants screened all non-critically ill ED patients for eligibility and willingness to participate and administered an interview-based survey that included questions on demographic and clinical characteristics, perceived illness severity, and acceptability of alternatives to traditional emergency care for acute illness and injuries. We calculated the proportions and 95% confidence intervals for subjects who found alternative transport modes and destinations acceptable and developed a log-binomial regression model to identify patient characteristics associated with acceptability of alternative modes of transport and alternative destinations. Complete data were available on 1,058 subjects. Forty-two percent of the study sample arrived to the ED via emergency medical services (EMS). Over two-thirds of the study sample (68.2%) was willing to consider transport via either taxi or medical transport van and 69.0% was willing to consider either transportation to an urgent care center or their primary care physician's office. Other alternatives, including delayed EMS response time, were less frequently endorsed as acceptable alternatives. Subject characteristics associated with willingness to accept alternative modes of transportation included younger age, chief complaint, previous ED use, and place of residence (p < 0.05). Subject characteristics associated with willingness to accept alternative destinations included younger age, non-white race, lower patient acuity, and lower self-perceived illness severity (p < 0.05). In our ED, some patients found alternative transport modes and alternative destinations acceptable. We identified patient-level characteristics associated with willingness to accept alternatives; however, the predictive ability and clinical utility of these factors is limited. Future research should further explore the acceptability and effectiveness of these alternative care delivery options.

Stroke and Helicopter Emergency Medical Service Transports: An Analysis of 25,332 Patients.

OBJECTIVE: Helicopter emergency medical services (HEMS) are effective in time-sensitive illnesses, including stroke. Intravenous tissue plasminogen activator is beneficial for ischemic stroke within 4.5 hours of onset. This study analyzed the largest repository of US HEMS electronic medical record data characterizing demographic and logistical trends during stroke center accreditation. This study developed a methodology to aggregate, analyze, and report data from multiple providers. METHODS: This is a descriptive study of aggregate, deidentified data from 67 US providers from 2004 to 2011. Retrospective data including age, ethnicity, total transport time, mission type, and locality were analyzed. The effect of primary stroke center (PSC) designation was assessed for 2011. RESULTS: A total of 25,332 patients were transported for "stroke." Stroke increased from 1.4% to 3.9% during the study. Ninety-six percent of transports arrived at definitive care within 2 hours. Seventy-two percent of transports were "interfacility," and 58% were from "rural" or "super-rural" localities. Seventy-nine percent of 2011 transports were to PSCs. Ethnicity and age were significant barriers to transport to PSCs (P < .001). CONCLUSIONS: HEMS has increased access to stroke care for super-rural, rural, and urban communities offering timely transport within the treatment window if symptoms are recognized within 2.5 hours of onset. This study created a methodology for future multicenter aggregate data studies.

The state of innovative emergency medical service programs in the United States.

BACKGROUND: The primary objective of this study was to determine how EMS organizations that are piloting patient-centered treatment and transport protocols are approaching the challenges of implementation, reimbursement, and quality assurance. We were particularly interested in determining if these pilot efforts have raised any patient safety concerns. METHODS: We conducted a set of discussions with a small group of key EMS stakeholders regarding the status of pioneering efforts to develop and evaluate innovative approaches to EMS in the United States. RESULTS: We had discussions with 9 EMS agencies to better understand their innovative programs, including: the history of their service policy and procedure for transports that do not require emergency department care; the impact of their innovative program on service costs and/or cost savings; any reimbursement issues or changes; patient safety; patient satisfaction; and overall impression as well as recommendations for other EMS systems considering adoption of this policy. CONCLUSIONS: In general, EMS systems are not reimbursed for service unless the patient is transported to an ED. Spokespersons for all nine sites covered by this project said that this policy creates a powerful disincentive to implementing pilot programs to safely reduce EMS use by directing patients to more appropriate sites of care or proactively treating them in their homes. Even though private and public hospitals and payers typically benefit from these programs, they have been generally reluctant to offer support. This raises serious questions about the long-term viability of these programs.

Military trauma system in Afghanistan: lessons for civil systems?

PURPOSE OF REVIEW: This review focuses on development and maturation of the tactical evacuation and en route care capabilities of the military trauma system in Afghanistan and discusses hard-learned lessons that may have enduring relevance to civilian trauma systems. RECENT FINDINGS: Implementation of an evidence-based, data-driven performance improvement programme in the tactical evacuation and en route care elements of the military trauma system in Afghanistan has delivered measured improvements in casualty care outcomes. SUMMARY: Transfer of the lessons learned in the military trauma system operating in Afghanistan to civilian trauma systems with a comparable burden of prolonged evacuation times may be realized in improved patient outcomes in these systems.

Impact of emergency medical helicopter transport directly to a university hospital trauma center on mortality of severe blunt trauma patients until discharge.

INTRODUCTION: The benefits of transporting severely injured patients by helicopter remain controversial. This study aimed to analyze the impact on mortality of helicopter compared to ground transport directly from the scene to a University hospital trauma center. METHODS: The French Intensive Care Research for Severe Trauma cohort study enrolled 2,703 patients with severe blunt trauma requiring admission to University hospital intensive care units within 72 hours. Pre-hospital and hospital clinical data, including the mode of transport, (helicopter (HMICU) versus ground (GMICU), both with medical teams), were recorded. The analysis was restricted to patients admitted directly from the scene to a University hospital trauma center. The main endpoint was mortality until ICU discharge. RESULTS: Of the 1,958 patients analyzed, 74% were transported by GMICU, 26% by HMICU. Median injury severity score (ISS) was 26 (interquartile range (IQR) 19 to 34) for HMICU patients and 25 (IQR 18 to 34) for GMICU patients. Compared to GMICU, HMICU patients had a higher median time frame before hospital admission and were more intensively treated in the pre-hospital phase. Crude mortality until hospital discharge was the same regardless of pre-hospital mode of transport. After adjustment for initial status, the risk of death was significantly lower (odds ratio (OR): 0.68, 95% confidence interval (CI) 0.47 to 0.98, P = 0.035) for HMICU compared with GMICU. This result did not change after further adjustment for ISS and overall surgical procedures. CONCLUSIONS: This study suggests a beneficial impact of helicopter transport on mortality in severe blunt trauma. Whether this association could be due to better management in the pre-hospital phase needs to be more thoroughly assessed.

How effective are programs at managing transition from hospital to home? A case study of the Australian Transition Care Program.

BACKGROUND: An increasing demand for acute care services due in part to rising proportions of older people and increasing rates of chronic diseases has led to new models of post-acute care for older people that offer coordinated discharge, ongoing support and often a focus on functional restoration. Overall, review of the literature suggests there is considerable uncertainty around the effectiveness and resource implications of the various model configurations and delivery approaches. In this paper, we review the current evidence on the efficacy of such programs, using the Australian Transition Care Program as a case study. DISCUSSION: The Australian Transition Care Program was established at the interface of the acute and aged care sectors with particular emphasis on transitions between acute and community care. The program is intended to enable a significant proportion of care recipients to return home, rather than prematurely enter residential aged care, optimize their functional capacity, and reduce inappropriate extended lengths of hospital stay for older people. Broadly, the model is configured and targeted in accordance with programs reported in the international literature to be effective. Early evaluations suggest good acceptance of the program by hospitals, patients and staff. Ultimately, however, the program's place in the array of post-acute services should be determined by its demonstrated efficacy relative to other services which cater for similar patient groups. SUMMARY: Currently there is a lack of robust evaluation to provide convincing evidence of efficacy, either from a patient outcome or cost reduction perspective. As the program expands and matures, there will be opportunity to scrutinise the systematic effects, with lessons for both Australian and international policy makers and clinical leaders.

[Transport with ongoing cardiopulmonary resuscitation - when does is it make sense?]. / Kardiopulmonale Reanimation (CPR) - Transport Unter CPR - Wann macht es Sinn?

The currently valid guidelines for resuscitation of the European Resuscitation Council (ERC) do not give any unambiguous recommendations for "transport with ongoing cardiopulmonary resuscitation". Furthermore, up to now there are no generally accepted criteria for terminating cardiopulmonary resuscitation, apart from certain signs of death. In spite of the generally poor outcome of patients being transported with ongoing cardiopulmonary resuscitation, there are a number of positive case reports and undisputable indications (e.g., in cases with a potentially reversible cause of cardiac arrest). The increase observed over the past few years in the number of patients being transported under cardiopulmonary resuscitation has as yet not been reflected in an improved prognosis for these patients. The use of mechanical chest compression devices with a better quality of chest compression, also under transport conditions, may have an influence on the number transports but this has not yet been evaluated sufficiently with regard to patient outcome. However, the decision to transport a patient resides with the responsible emergency physician who has to evaluate the prognosis for the patient on an individual basis.

Emerging technologies for pediatric and adult trauma care.

PURPOSE OF REVIEW: Current Emergency Medical Service protocols rely on provider-directed care for evaluation, management and triage of injured patients from the field to a trauma center. New methods to quickly diagnose, support and coordinate the movement of trauma patients from the field to the most appropriate trauma center are in development. These methods will enhance trauma care and promote trauma system development. RECENT FINDINGS: Recent advances in machine learning, statistical methods, device integration and wireless communication are giving rise to new methods for vital sign data analysis and a new generation of transport monitors. These monitors will collect and synchronize exponentially growing amounts of vital sign data with electronic patient care information. The application of advanced statistical methods to these complex clinical data sets has the potential to reveal many important physiological relationships and treatment effects. SUMMARY: Several emerging technologies are converging to yield a new generation of smart sensors and tightly integrated transport monitors. These technologies will assist prehospital providers in quickly identifying and triaging the most severely injured children and adults to the most appropriate trauma centers. They will enable the development of real-time clinical support systems of increasing complexity, able to provide timelier, more cost-effective, autonomous care.
