Comparative Effectiveness of Emergency Resuscitative Thoracotomy versus Closed Chest Compressions among Patients with Critical Blunt Trauma: A Nationwide Cohort Study in Japan

Background

Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions.

Methods

This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching.

Results

In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1%) underwent emergency resuscitative thoracotomy and 893 (64.9%) received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001) and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001). Multivariable generalized mixed-effects regression analysis with and without a propensity score-matched dataset revealed that the odds ratio for an unfavorable survival rate after 24 h was lower for emergency resuscitative thoracotomy than for closed-chest compressions (P < 0.001).

Conclusions

Emergency resuscitative thoracotomy was independently associated with decreased odds of a favorable survival rate compared to closed-chest compressions.     

Feasibility of AmbulanCe-Based Telemedicine (FACT) Study: Safety,Feasibility and Reliability of Third Generation In-Ambulance Telemedicine

Background

Telemedicine is currently mainly applied as an in-hospital service, but this technology also holds potential to improve emergency care in the prehospital arena. We report on the safety, feasibility and reliability of in-ambulance teleconsultation using a telemedicine system of the third generation.

Methods

A routine ambulance was equipped with a system for real-time bidirectional audio-video communication, automated transmission of vital parameters, glycemia and electronic patient identification. All patients ( ≥18 years) transported during emergency missions by a Prehospital Intervention Team of the Universitair Ziekenhuis Brussel were eligible for inclusion. To guarantee mobility and to facilitate 24/7 availability, the teleconsultants used lightweight laptop computers to access a dedicated telemedicine platform, which also provided functionalities for neurological assessment, electronic reporting and prehospital notification of the in-hospital team. Key registrations included any safety issue, mobile connectivity, communication of patient information, audiovisual quality, user-friendliness and accuracy of the prehospital diagnosis.

Results

Prehospital teleconsultation was obtained in 41 out of 43 cases (95.3%). The success rates for communication of blood pressure, heart rate, blood oxygen saturation, glycemia, and electronic patient identification were 78.7%, 84.8%, 80.6%, 64.0%, and 84.2%. A preliminary prehospital diagnosis was formulated in 90.2%, with satisfactory agreement with final in-hospital diagnoses. Communication of a prehospital report to the in-hospital team was successful in 94.7% and prenotification of the in-hospital team via SMS in 90.2%. Failures resulted mainly from limited mobile connectivity and to a lesser extent from software, hardware or human error. The user acceptance was high.

Conclusions

Ambulance-based telemedicine of the third generation is safe, feasible and reliable but further research and development, especially with regard to high speed broadband access, is needed before this approach can be implemented in daily practice.     

Nontraumatic Hypotension and Shock in the Emergency Department and the Prehospital setting,Prevalence, Etiology,and Mortality: A Systematic Review

Background

Acute patients presenting with hypotension in the prehospital or emergency department (ED) setting are in need of focused management and knowledge of the epidemiology characteristics might help the clinician. The aim of this review was to address prevalence, etiology and mortality of nontraumatic hypotension (SBP ≤ 90 mmHg) with or without the presence of shock in the prehospital and ED setting.

Methods

We performed a systematic literature search up to August 2013, using Medline, Embase, Cinahl, Dare and The Cochrane Library. The analysis and eligibility criteria were documented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-guidelines) and The Cochrane Collaboration. No restrictions on language, publication date, or status were imposed. We used the Newcastle-Ottawa quality assessment scale (NOS-scale) and the Strengthening the Reporting of Observational studies in Epidemiology (STROBE-statement) to assess the quality.

Results

Six observational studies were considered eligible for analysis based on the evaluation of 11,880 identified papers. Prehospital prevalence of hypotension was 19.5/1000 emergency medicine service (EMS) contacts, and the prevalence of hypotensive shock was 9.5-19/1000 EMS contacts with an inhospital mortality of shock between 33 to 52%. ED prevalence of hypotension was 4-13/1000 contacts with a mortality of 12%. Information on mortality, prevalence and etiology of shock in the ED was limited. A meta-analysis was not feasible due to substantial heterogeneity between studies.

Conclusion

There is inadequate evidence to establish concise estimates of the characteristics of nontraumatic hypotension and shock in the ED or in the prehospital setting. The available studies suggest that 2% of EMS contacts present with nontraumatic hypotension while 1-2% present with shock. The inhospital mortality of prehospital shock is 33-52%. Prevalence of hypotension in the ED is 1% with an inhospital mortality of 12%. Prevalence, etiology and mortality of shock in the ED are not well described.     

Experience in Prehospital Endotracheal Intubation Significantly Influences Mortality of Patients with Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis

Background

Patients with severe traumatic brain injury (TBI) are at high risk for airway obstruction and hypoxia at the accident scene, and routine prehospital endotracheal intubation has been widely advocated. However, the effects on outcome are unclear. We therefore aim to determine effects of prehospital intubation on mortality and hypothesize that such effects may depend on the emergency medical service providers’ skill and experience in performing this intervention.

Methods and Findings

PubMed, Embase and Web of Science were searched without restrictions up to July 2015. Studies comparing effects of prehospital intubation versus non-invasive airway management on mortality in non-paediatric patients with severe TBI were selected for the systematic review. Results were pooled across a subset of studies that met predefined quality criteria. Random effects meta-analysis, stratified by experience, was used to obtain pooled estimates of the effect of prehospital intubation on mortality. Meta-regression was used to formally assess differences between experience groups. Mortality was the main outcome measure, and odds ratios refer to the odds of mortality in patients undergoing prehospital intubation versus odds of mortality in patients who are not intubated in the field. The study was registered at the International Prospective Register of Systematic Reviews (PROSPERO) with number CRD42014015506. The search provided 733 studies, of which 6 studies including data from 4772 patients met inclusion and quality criteria for the meta-analysis. Prehospital intubation by providers with limited experience was associated with an approximately twofold increase in the odds of mortality (OR 2.33, 95% CI 1.61 to 3.38, p<0.001). In contrast, there was no evidence for higher mortality in patients who were intubated by providers with extended level of training (OR 0.75, 95% CI 0.52 to 1.08, p = 0.126). Meta-regression confirmed that experience is a significant predictor of mortality (p = 0.009).

Conclusions

Effects of prehospital endotracheal intubation depend on the experience of prehospital healthcare providers. Intubation by paramedics who are not well skilled to do so markedly increases mortality, suggesting that routine prehospital intubation of TBI patients should be abandoned in emergency medical services in which providers do not have ample training, skill and experience in performing this intervention.     

Bringing the hospital to the patient: first treatment of stroke patients at the emergency site

Background

Early treatment with rt-PA is critical for favorable outcome of acute stroke. However, only a very small proportion of stroke patients receive this treatment, as most arrive at hospital too late to be eligible for rt-PA therapy.

Methods and Findings

We developed a “Mobile Stroke Unit”, consisting of an ambulance equipped with computed tomography, a point-of-care laboratory system for complete stroke laboratory work-up, and telemedicine capabilities for contact with hospital experts, to achieve delivery of etiology-specific and guideline-adherent stroke treatment at the site of the emergency, well before arrival at the hospital. In a departure from current practice, stroke patients could be differentially treated according to their ischemic or hemorrhagic etiology even in the prehospital phase of stroke management. Immediate diagnosis of cerebral ischemia and exclusion of thrombolysis contraindications enabled us to perform prehospital rt-PA thrombolysis as bridging to later intra-arterial recanalization in one patient. In a complementary patient with cerebral hemorrhage, prehospital diagnosis allowed immediate initiation of hemorrhage-specific blood pressure management and telemedicine consultation regarding surgery. Call-to-therapy-decision times were 35 minutes.

Conclusion

This preliminary study proves the feasibility of guideline-adherent, etiology-specific and causal treatment of acute stroke directly at the emergency site.     

Prehospital Thrombolysis: A Manual from Berlin

In acute ischemic stroke, time from symptom onset to intervention is a decisive prognostic factor. In order to reduce this time, prehospital thrombolysis at the emergency site would be preferable. However, apart from neurological expertise and laboratory investigations a computed tomography (CT) scan is necessary to exclude hemorrhagic stroke prior to thrombolysis. Therefore, a specialized ambulance equipped with a CT scanner and point-of-care laboratory was designed and constructed. Further, a new stroke identifying interview algorithm was developed and implemented in the Berlin emergency medical services. Since February 2011 the identification of suspected stroke in the dispatch center of the Berlin Fire Brigade prompts the deployment of this ambulance, a stroke emergency mobile (STEMO). On arrival, a neurologist, experienced in stroke care and with additional training in emergency medicine, takes a neurological examination. If stroke is suspected a CT scan excludes intracranial hemorrhage. The CT-scans are telemetrically transmitted to the neuroradiologist on-call. If coagulation status of the patient is normal and patient''s medical history reveals no contraindication, prehospital thrombolysis is applied according to current guidelines (intravenous recombinant tissue plasminogen activator, iv rtPA, alteplase, Actilyse).Thereafter patients are transported to the nearest hospital with a certified stroke unit for further treatment and assessment of strokeaetiology. After a pilot-phase, weeks were randomized into blocks either with or without STEMO care. Primary end-point of this study is time from alarm to the initiation of thrombolysis. We hypothesized that alarm-to-treatment time can be reduced by at least 20 min compared to regular care.

First Things First: Effectiveness and Scalability of a Basic Prehospital Trauma Care Program for Lay First-Responders in Kampala,Uganda

Background

We previously showed that in the absence of a formal emergency system, lay people face a heavy burden of injuries in Kampala, Uganda, and we demonstrated the feasibility of a basic prehospital trauma course for lay people. This study tests the effectiveness of this course and estimates the costs and cost-effectiveness of scaling up this training.

Methods and Findings

For six months, we prospectively followed 307 trainees (police, taxi drivers, and community leaders) who completed a one-day basic prehospital trauma care program in 2008. Cross-sectional surveys and fund of knowledge tests were used to measure their frequency of skill and supply use, reasons for not providing aid, perceived utility of the course and kit, confidence in using skills, and knowledge of first-aid. We then estimated the cost-effectiveness of scaling up the program.At six months, 188 (62%) of the trainees were followed up. Their knowledge retention remained high or increased. The mean correct score on a basic fund of knowledge test was 92%, up from 86% after initial training (n = 146 pairs, p = 0.0016). 97% of participants had used at least one skill from the course: most commonly haemorrhage control, recovery position and lifting/moving and 96% had used at least one first-aid item. Lack of knowledge was less of a barrier and trainees were significantly more confident in providing first-aid. Based on cost estimates from the World Health Organization, local injury data, and modelling from previous studies, the projected cost of scaling up this program was $0.12 per capita or $25–75 per life year saved. Key limitations of the study include small sample size, possible reporter bias, preliminary local validation of study instruments, and an indirect estimate of mortality reduction.

Conclusions

Lay first-responders effectively retained knowledge on prehospital trauma care and confidently used their first-aid skills and supplies for at least six months. The costs of scaling up this intervention to cover Kampala are very modest. This may be a cost-effective first step toward developing formal emergency services in Uganda other resource-constrained settings. Further research is needed in this critical area of trauma care in low-income countries.     

Pulse oximetry at the roadside: a study of pulse oximetry in immediate care.

The measurement of tissue oxygen saturation with a pulse oximeter is of proved value in the hospital setting. The development of a portable oximeter has allowed this investigation to be performed during the prehospital phase of a patient''s care. Pulse oximetry was performed at the roadside in 25 patients with abnormal trauma scores and found to be of benefit in detecting and monitoring hypoxia in patients with airway obstruction, depressed respiration due to head injury, and, in particular, with closed chest injuries. There were no practical difficulties associated with the use of the instrument either at the roadside or in a moving ambulance. The portable pulse oximeter is a valuable aid in the prehospital monitoring of patients with trauma.     

Integration othe MG 50 into the routine of a hospital transfusion center

Groupamatic MG 50 equipment looks to be quite well adapted to suit the needs of small or medium size blood transfusion centers, in which the number of blood grouping determinations daily processed is in the range of 100 to 500. In its present configuration (after some modifications have been brought in), the MG 50 offers significant advantages which will be discussed in detail. For a batch of 58 samples tested in one hour on twelve channels a single technician is required instead of 3 to 4; sample supply of equipment is therefore made in a more regular way. In case of run interrupt a single series of 12 determinations is implicated and can be immediately checked. The whole analysis process is limited to twice 11 minutes due to the continuous agitation of discs. The tubing pump priming is automatically performed and the reagent homogeneity is better insured; the presence of dilution tubes is easily controlled. Different programs are easily interchangeable and make the use of equipment smooth. We do think that MG 50 allows a better distribution of work throughout the day and accepts emergency blood grouping requests without any special difficulty.     

Descriptive Analysis of Patients’ EMS Use Related to Severity in Tokyo: A Population-Based Observational Study

Introduction

Few studies are available on the clinical characteristics of patients using emergency medical transports in Japan. In this study, we aimed to investigate reasons for emergency medical transports and their relation to clinical severity.

Methods

We conducted a 3-year population-based observational study of patients transported by ambulance to emergency departments (ED) in the capital of Japan, Tokyo, which has a population of about 13 million. Demographic data, reasons for transport, and the severity of initial assessment at ED were recorded. Logistic regression was used to determine the odds of the clinical severity of each reason for transport.

Results

The number of emergency medical transports in the three-year study period was 1,832,637. Mean age was 53±26. Males were 976,142 (53%). Overall, 92% of all transported patients were in a mild or moderate medical state and patients with the 17 most frequent reasons for transport occupied 82% (1,506,017) of all transports. Pain was the most frequent reason for transport, followed by traffic accident. Considering all the patients and their reasons for transport, patients whose reason was pain or a traffic accident (29% of all patients) were in a relatively mild state compared with patients with other reasons for transport. Patients in an altered mental state in the prehospital setting (6.8% of all patients) were in a more severe medical state than other patients.

Conclusions

In Tokyo, Japan, 92% of transported patients were in a mild or moderate medical state. In particular, most patients from traffic accidents were in a mild state, even though traffic accidents were the second most frequent reason for transport. Patients in an altered mental state were most likely to be in a severe medical state.     

Current concepts in trauma: 1. Principles and directions for development.

Despite considerable advances in treatment in the last 20 years, trauma continues to be the main cause of disability and death for people under the age of 40 years. The outcome after injury has been improved by the introduction of advanced prehospital life support, early transfer and the establishment of specialized programs. Trauma care is governed by two underlying principles: early definitive management and a continuum of treatment from the time of injury to the return to the activities of daily life. Most important, a team approach is necessary in the treatment of the trauma patient. This requires the cooperation and participation of prehospital emergency personnel and referring hospitals as well as multidisciplinary collaboration within each trauma centre. There continue to be areas of neglect that prevent optimal trauma care and must be addressed.     

Educating Internists in Emergency Medicine

The education of internists in emergency medicine needs to be thoughtfully planned by those involved in their education. Objectives for their emergency medicine rotation include the recognition and initial treatment of true medical and surgical emergencies, clinical experience with and knowledge of common acute primary care problems, the ability to handle several patients with problems having different degrees of urgency, effective use of consultants in the follow-up and management of difficult patients and a knowledge of and clinical experience with the prehospital care system. A curriculum should be designed to give the resident a core of didactic material in addition to supervised clinical experience. The rotation should be evaluated by both residents and faculty from internal medicine and emergency medicine to determine if it is accomplishing the objectives set forth.     

Evaluation of Video-Assisted Thoracoscopic Surgery for Pulmonary Metastases: A Meta-Analysis

Background

To evaluate the evidence comparing video-assisted thoracic surgery (VATS) and open thoracotomy in the treatment of metastatic lung cancer using meta-analytical techniques.

Methods

A literature search was undertaken until July 2013 to identify the comparative studies evaluating disease-free survival rates and survival rates. The pooled odds ratios (OR) and the 95% confidence intervals (95% CI) were calculated with the fixed or random effect models.

Results

Six retrospective studies were included in our meta-analysis. These studies included a total of 546 patients: 235 patients were treated with VATS, and 311 patients were treated with open thoracotomy. The VATS and the thoracotomy did not demonstrate a significant difference in the 1-,3-,5-year survival rates and the 1-year disease-free survival rate. There were significant statistical differences between the 3-year disease free survival rate (p = 0.04), which favored open thoracotomy.

Conclusions

The VATS approach is a safe and feasible treatment in terms of the survival rate for metastatic lung cancer compared with the thoracotomy. The 3-year disease-free survival rate in the VATS group is inferior to that of open thoracotomy. The VATS approach could not completely replace open thoracotomy.     

Medical direction and control of emergency medical services in Canada.

OBJECTIVE: To determine the level of physician involvement in prehospital emergency medical services (EMS) in Canada, as compared with published principles of medical control and direction. DESIGN: Mail and telephone survey by means of a questionnaire from March to November 1991. SETTING: All Canadian provinces and territories. PARTICIPANTS: Fifty-six key prehospital EMS physicians, senior government administrators and senior representatives of the agencies responsible for licensing physicians in each province or territory. MAIN OUTCOME MEASURES: Responses to questions regarding the legislation, organization, administration, practice and regulation of medical direction and control by physicians in each province or territory. RESULTS: EMS legislation describing medical direction and control was completely lacking in five provinces and both territories and was incomplete in the remainder. Provincial guidelines written by physicians for prehospital patient care were present in only four provinces. Formal organization of medical directors varied from none to partially remunerated networks. Regional medical-director systems were present in three provinces, and local medical directors were required for all communities in three. Most rural ambulance services were found to engage physicians only when there was local interest. CONCLUSIONS: The level of physician involvement in the medical direction and control of EMS appears to be inconsistent across Canada and insufficient in most jurisdictions, as compared with accepted principles.     

The OPALS Major Trauma Study: impact of advanced life-support on survival and morbidity

Background

To date, the benefit of prehospital advanced life-support programs on trauma-related mortality and morbidity has not been established

Methods

The Ontario Prehospital Advanced Life Support (OPALS) Major Trauma Study was a before–after systemwide controlled clinical trial conducted in 17 cities. We enrolled adult patients who had experienced major trauma in a basic life-support phase and a subsequent advanced life-support phase (during which paramedics were able to perform endotracheal intubation and administer fluids and drugs intravenously). The primary outcome was survival to hospital discharge.

Results

Among the 2867 patients enrolled in the basic life-support (n = 1373) and advanced life-support (n = 1494) phases, characteristics were similar, including mean age (44.8 v. 47.5 years), frequency of blunt injury (92.0% v. 91.4%), median injury severity score (24 v. 22) and percentage of patients with Glasgow Coma Scale score less than 9 (27.2% v. 22.1%). Survival did not differ overall (81.1% among patients in the advanced life-support phase v. 81.8% among those in the basic life-support phase; p = 0.65). Among patients with Glasgow Coma Scale score less than 9, survival was lower among those in the advanced life-support phase (50.9% v. 60.0%; p = 0.02). The adjusted odds of death for the advanced life-support v. basic life-support phases were nonsignificant (1.2, 95% confidence interval 0.9–1.7; p = 0.16).

Interpretation

The OPALS Major Trauma Study showed that systemwide implementation of full advanced life-support programs did not decrease mortality or morbidity for major trauma patients. We also found that during the advanced life-support phase, mortality was greater among patients with Glasgow Coma Scale scores less than 9. We believe that emergency medical services should carefully re-evaluate the indications for and application of prehospital advanced life-support measures for patients who have experienced major trauma.Each year in the United States, an estimated 500 000 adult patients are transported to hospital after experiencing major trauma.^1,2 Major trauma can be described as life-or limb-threatening injury due to blunt force, penetrating injury or burn injury. Considering both frequency and associated mortality, major trauma is the second most important condition for children and the fourth most important condition for adults treated by emergency medical service providers.² About 20% of these patients die, and many survivors are left with permanent disability.Throughout most urban areas of the United States and Canada, paramedics provide prehospital advanced life-support to many of these critically injured patients. Advanced life-support protocols include advanced airway management (endotracheal intubation) and intravenous fluid therapy. In contrast, basic life-support providers administer oxygen, ventilate with a bag valve mask, and provide immobilization and dressings. The relative effectiveness of community-based advanced life-support programs for major trauma patients has not been clearly established, and there have been calls for larger and more rigorously designed studies.^3–5Endotracheal intubation in the field has not been proven to reduce mortality and morbidity among severely injured patients, and there are concerns that performing this difficult task under trying conditions may cause harm.^6,7 The value of prehospital intravenous resuscitation has also been questioned.^8,9 In addition, there are concerns that the on-scene time spent providing advanced life-support measures may actually delay life-saving expeditious transfer to the hospital and the operating room.¹⁰ To date, no large controlled clinical trials have been conducted to evaluate the impact of prehospital advanced life-support programs on trauma-related mortality and morbidity.³As part of the Ontario Prehospital Advanced Life Support (OPALS) studies, we recently demonstrated that advanced life-support programs had no impact on the outcomes of patients who had experienced cardiac arrest, but they did lead to significant improvement in survival among patients with respiratory distress.^11,12 The primary objective of the current study, the OPALS Major Trauma Study, was to assess any change in survival that might result from the systemwide introduction of prehospital advanced life-support programs in multiple cities with existing basic life-support programs provided through emergency medical services. We also evaluated the impact of advanced life-support on morbidity and processes of care.     

Randomised trial of a mobile coronary care unit for emergency calls.

A randomised trial was conducted to assess the value of sending a mobile coronary care unit (MCCU) to all emergency calls other than those for children or for patients injured in road-traffic accidents or brawls. Over 15 months 6223 calls for emergency ambulances were considered for the study, but a routine ambulance had to be dispatched on 2583 occasions because the MCCU was not available. A group of 1664 patients was randomly allocated to transport by the MCCU and 1676 patients to routine transport. In these groups the prehospital mortality among patients with heart attacks was 45% and 47%, and no patient survived resuscitation attempts long enough to leave hospital. During the same period general practitioners sent 190 patients with heart attacks to hospital in routine ambulances and none of them died during the interval between the call for the ambulance and arrival at hospital. Although it may be worth equipping all emergency ambulances with a defibrillator, MCCUs as at present envisaged will not appreciably affect mortality from heart attacks.     

Penetrating chest wound: a case report.

An unusual penetrating chest injury was caused by a ball-point pen. Because of apparent penetration of the heart, preparations were made for an emergency open-heart procedure before emergency thoracotomy was undertaken, with the pen still in situ. The pen had bruised the epicardium but had not penetrated the pericardial sac. After removal of the pen, the wound was closed and a chest tube left in place. Recovery, apart from minor degrees of basal atelectasis, pleural effusion and wound infection, was uneventful. The outcome was consistent with that associated with current aggressive management of penetrating chest injuries. Management is based on three approaches. The primary one is intercostal thoracostomy tube drainage and fluid and blood replacement. In cases of massive hemorrhage or air leak, thoracotomy is necessary. The third approach is to prevent post-traumatic pulmonary insufficiency by using fine, high-efficiency filters during blood transfusion, avoiding excessive administration of intravenous fluids, performing tracheostomy after prolonged endotracheal intubation, and using a volume respirator with positive end-expiratory pressure. The average mortality for penetrating wounds of the heart is 25%.
