Trauma Care in India and Germany

Background

Road traffic accidents are among the leading causes of death worldwide in individuals younger than 45 years. In both India and Germany, there has been an increase in registered motor vehicles over the last decades. However, while the number of traffic accident victims steadily dropped in Germany, there has been a sustained increase in India. We analyze this considering the sustained differences in rescue and trauma system status.

Questions/purposes

We compared India and Germany in terms of (1) vehicular infrastructure and causes of road traffic accident-related trauma, (2) burden of trauma, and (3) current trauma care and prevention, and (4) based on these observations, we suggested how India and other countries can enhance trauma care and prevention.

Methods

Data for Germany were obtained from federal statistical databases, German Automobile Club, and German Trauma Registry. Data from India were available from the Ministry of Road Transport and Highways. We also performed a standardized literature search of PubMed for India and Germany using the following key words: “road traffic accidents”, “prevention”, “prehospital trauma care”, “trauma system”, “trauma registry”, “trauma centers”, and “development of vehicles.”

Results

The total number of registered motor vehicles increased 473-fold in India and 100-fold in Germany from 1951 to 2011. The number of road traffic deaths increased in both countries until 1970, but thereafter decreased in Germany (3606 in 2012) while continuing to increase in India (142,485 in 2011). The differences between Germany and India relate to the relative sizes and populations of the countries (1:9 and 1:15, respectively), and differences in prevention and prehospital care (nationwide versus big cities) and hospital trauma systems (nationwide versus exceptional).

Conclusions

Improvement requires attention to three major issues: (1) prevention through infrastructure, traffic laws, mandatory licensing; (2) establishment of a prehospital care system; and (3) establishment of regional trauma centers and a trauma registry.     

Medizinisches Qualitätsmanagement mit Hilfe ausgewählter Zieldiagnosen

Finding the answers to various questions in medical quality management is hampered by the current possibilities for documentation in emergency medicine.The available tools for documentation such as the DIVI protocol for emergency physicians and databases such as MIND are inadequate for assessing prehospital care with a view to subsequent diagnosis-related evaluation. Appropriate test criteria must first be determined for data analysis in quality management with which the quality of prehospital care for specific diagnoses can be appraised. This article presents a survey of the test criteria for diagnoses encountered in everyday emergency medicine: “acute coronary syndrome,” “acute apoplexy,” “severe craniocerebral trauma,” and “multiple trauma.” These are derived from current action guidelines of the medical specialty associations.Thus, in the future, it will be possible to implement uniform data analysis and comprehensive nationwide quality management.     

Aktuelle Konzepte der Patientensicherheit

The “100,000 lives campaign” initiated a wide-spread implementation of rapid response teams in the United States. A standardized rapid response system (RRS) is designed to reduce the preventable mortality of hospitalized patients who frequently have progressive signs of physiological deterioration minutes to hours before cardiac arrest. The implementation and maturation of a team-based RRS has been shown to significantly reduce the incidence of “COR zero” calls and, in some studies, the in-hospital mortality rate. An alternative model to rapid response teams has been recently proposed which is based on defined clinical triggers to initiate a “rapid response escalation”. This clinical triggers program overcomes the classic limitations of a team-based system, such as the overuse of resources and the fragmentation of patient care. The present review outlines the basic RRS concept with a focus on the debate related to the “perfect” patient safety system, namely the validity of a distinct rapid response teams approach versus a trigger-based escalation modality. The implementation of a standardized RRS should also be considered in German hospitals with the aim of improving patient safety and reducing preventable in-hospital mortality.     

Außerklinische Notfallmedizin in Deutschland, Österreich und der Schweiz

Background

Only randomized clinical trials can improve the outcome of life-threatening injuries or diseases but observations from England and North America suggest that the number of such randomized clinical trials is decreasing. In this study contributions from German speaking countries with regards to randomized clinical trials in emergency medicine over the last 22 years were investigated.

Methods

The Medline database was searched from January 1990 to December 2012 for prospective randomized clinical trials in the prehospital setting using the criteria “cardiac arrest”, “cardiopulmonary resuscitation”, “multiple trauma”, “hemorrhagic shock”, “head trauma”, “stroke” as well as myocardial infarction and emergency medical service. Only studies originating from Germany, Austria or Switzerland were included.

Results

A total of 474 studies were found and 25 studies (5.3?%) fulfilled the inclusion criteria. In the last 22 years German speaking countries have published approximately one prospective, randomized, clinical trial per year on prehospital emergency medicine. The median number of patients included in the trials was 159 (minimum 16, maximum 1,219). Most (80?%) studies originated from Germany and most (64?%) studies were conducted by anesthesiology departments. Cardiac arrest was the most frequent subject of the investigated studies. Approximately 50?% of the studies had financial support from industrial companies.

Conclusion

A significant increase or decrease in the number of prospective randomized clinical trials in the out-of-hospital setting could not be found in German speaking countries despite the fact that the absolute numbers of studies had increased. Only about one prospective, randomized clinical trial with an emergency medicine core tracer diagnosis originated from Germany, Austria and Switzerland per year.     

"Highlights" in emergency medicine -- severe head trauma, polytrauma and cardiac arrest

According to scientific publications focusing on emergency medicine and published in international journals in the past few months, new and clinically important results can be identified. In patients with severe head trauma (SHT), application of hypertonic solutions is possible; long term outcome, however, is not improved by this measure. Prehospital capnometry is important, because otherwise up to 40 % of all mechanically ventilated patients are hypoventilated. In a study in 200 patients with prehospital cardiac arrest and ventricular fibrillation as initial cardiac rhythm, subgroup analysis (alarm-response time > 5 min) showed an increase in survival rate (14 % vs. 2 %), if defibrillation was proceeded by 3 min of conventional cardiopulmonary resuscitation (CPR) for reperfusion. If ACD ("active compression decompression")-CPR is combined with a specific ventilatory valve ("inspiratory impedance threshold device", ITD) which does not allow passive inspiration, survival rate after cardiac arrest is increased for up to 24 h. Such a device facilitates an increase in venous return to the heart during decompression of the thorax. High-dose adrenalin for intrahospital CPR in children is not associated with better survival but with worse outcome. Comparison of an emergency medical service (EMS) system from U.K. with paramedics and a physician-staffed German EMS system demonstrated that survival rate following prehospital cardiac arrest is markedly increased with doctors on board. The European multicentre trial comparing vasopressin vs. adrenalin as first vasopressor during CPR in 1219 patients did not reveal any differences between both groups. In subgroup analyses of patients with asystoly and prolonged CPR, vasopressin was superior without being associated with a benefit on neurological outcome. Further subgroup analyses revealed beneficial effects of amiodarone and thrombolysis during CPR. Thrombolysis during CPR apears to be associated with an increased rate of haemodynamic stabilisation without increased risk of bleeding complications. In a very clear advisory statement, the "International Liaison Committee on Resuscitation" (ILCOR) has recommended mild therapeutic hypothermia (i. e., cooling of cardiac arrest victims to 32 - 34 degrees C central body temperature for 12 - 24 h following cardiac arrest of cardiac etiology) not only for unconciuous patients with ventricular fibrillation as initial prehospital rhythm, but also for all other adult patients (other rhythms, intrahospital CPR) following cardiac arrest. In randomised controlled clinical trials, this therapy has markedly improved survival rate and neurological outcome. Such therapeutic cooling can be initiated nearly everywhere and with simple methods - like the infusion of ice-cold cristalloid solutions.     

Prehospital resuscitative thoracotomy for cardiac arrest after penetrating trauma: rationale and case series

OBJECTIVE: The purpose of this study is to present the rationale for an algorithm that describes the place of resuscitative thoracotomy in the prehospital management of a patient with penetrating chest injury, and to review a 6-year experience using this algorithm. METHODS: This study was a retrospective review of all cases where a prehospital thoracotomy was performed by the medical teams of the London Helicopter Emergency Medical Service. RESULTS: Thirty-nine prehospital thoracotomies were performed. Four (10%) patients survived, one with long-term disability. Factors associated with survival were stab wound, single cardiac wound, cardiac tamponade, and loss of pulse in the presence of an experienced prehospital doctor. CONCLUSION: Current evidence suggests that patients who suffer a cardiac arrest more than 10 minutes away from emergency room thoracotomy are very unlikely to survive. Prehospital thoracotomy is associated with a small number of survivors. This intervention should be considered if there is an appropriately experienced, trained, and equipped doctor present, who is acting within a trauma system with ongoing training and quality assurance.     

Paediatric cardiac arrest and resuscitation provided by physician-staffed emergency care units

Background: Most paediatric cardiac arrest studies have been conducted in the USA, where paramedics provide prehospital emergency care. We wanted to study the outcome of paediatric cardiac arrest patients in an emergency medical system which is based on physician staffed emergency care units.
Methods: We analysed retrospectively the files of 100 prehospital cardiac arrest patients from Southern Finland during a 10-year study period. The patients were less than 16 years of age.
Results: Fifty patients were declared dead on the scene (DOS) without attempted resuscitation, and cardiopulmonary resuscitation (CPR) was initiated in 50 patients. The sudden infant death syndrome was the most common cause of arrest in the DOS patients (68%) as well as in those receiving CPR (36%). Asystole was the initial cardiac rhythm in 70% of the patients in whom CPR was attempted. Resuscitation was successful in 13 patients, 8 of whom were ultimately discharged. Six of the patients survived with mild or no disability and 4 of them had near-drowning aetiology. In multivariate analysis, the short duration of CPR (≤15 min) was the only factor significantly associated with better survival.
Conclusions: Although prehospital care was provided by physicians, the overall rate of survival was found to be equally poor as reported from systems with paramedics. The only major difference between physician- and paramedic-staffed emergency care units is the ability of physicians to refrain from resuscitation already on the scene when prognosis is poor.     

Prehospital management by EMS of a potential non-heart-beating donor

After their prehospital management by EMS system and on-scene declaration of death, some patients are potential non-heart-beating donors. We report the case of refractory cardiac arrest, transferred to the hospital assisted by chest compression device. Time factor might be an important brake on prehospital recruitment. Future networks should attempt to shorten the time intervals.     

Notfallmedizinische Betreuung von Palliativpatienten am Lebensende

Background

The treatment of out-of-hospital palliative emergency care situations during cardiac arrest is a special situation. The prehospital emergency physician (EP) and the paramedic must be informed about the medical, legal, and ethical specifics of these situations, but this knowledge is not integrated within emergency medical curricula at all. We present a case study to discuss such legal and ethical specifics.

Methods

We retrospectively analysed six emergency cases with palliative care patients in the final stages of their illnesses. On the basis of these case studies, we present six different emergency cases with different regulatory frameworks for each EP and paramedic. In accordance with the Declaration of Helsinki, data were collected pseudonymously.

Results

The six case studies show therapeutic concepts concerning the emergency medical care of palliative care patients during cardiac arrest. The differences are apparent in the treatment given by EPs and by paramedics (such as whether to start or stop resuscitation). EPs and paramedics differ in their therapeutic approach to these specific situations (e.g. paramedics more often start resuscitation during cardiac arrest even though patients would refuse this according to their advance directives). These differences may be important for the patient and his or her caregivers.

Conclusions

Every EP and paramedic may be involved in the care of palliative care patients who are at the end of their lives. EPs and paramedics do not always adapt their treatment to the will or supposed will of the patient (especially in accordance with the new German law concerning advance directives). The reasons for this usually concern legal uncertainties. Therefore, EPs and paramedics should know that different legal meanings could be important in emergency medical care therapy of palliative care patients. A written “do not resuscitate” order as an advance directive must be evaluated as a desired therapeutic limitation.     

Aktuelle prähospitale und frühe klinische Therapie des akuten Koronarsyndroms (ACS)

A symposium on “Current prehospital and early clinical treatment of acute coronary syndrome (ACS)” was held in Heidelberg on 14.01.2006. In the course of this event the present importance of preclinical thrombolysis in emergency medical treatment of ACS was discussed, as were the challenges to preclinical emergency medical treatment of ACS from the viewpoint of a specialised intervention centre. In addition, reports were received on the actual emergency medical and early clinical care of ACS patients in Germany. Special emphasis was given to temporally optimal efficient patient care and friction-free link-up of prehospital and clinical care. The creation of interdisciplinary supraregional emeregency medical networks with particular reference to local infrastructure was discussed as an essential element in care. In a final digression, the question of whether the indications for prehospital thrombolysis might need to be widened in future and whether thrombolysis in cardiac attest (TROICA) will have a place was examined.     

Cardiopulmonary resuscitation after traumatic cardiac arrest is not always futile

INTRODUCTION: The use of guidelines regarding the termination or withholding of cardiopulmonary resuscitation (CPR) in traumatic cardiac arrest patients remains controversial. This study aimed to describe the outcomes for victims of penetrating and blunt trauma who received prehospital CPR. METHODS: We conducted a retrospective review of a statewide major trauma registry using data from 2001 to 2004. Subjects suffered penetrating or blunt trauma, received CPR in the field by paramedics and were transported to hospital. Demographics, vital signs, injury severity, prehospital time, length of stay and mortality data were collected and analysed. RESULTS: Eighty-nine patients met inclusion criteria. Eighty percent of these were blunt trauma victims, with a mortality rate of 97%, while penetrating trauma patients had a mortality rate of 89%. The overall mortality rate was 95%. Sixty-six percent of patients had a length of stay of less than 1 day. Four patients survived to discharge, of which two were penetrating and two were blunt injuries. Hypoxia and electrical injury were probable associated causes of two cardiac arrests seen in survivors of blunt injury. CONCLUSIONS: While only a small number of penetrating and blunt trauma patients receiving CPR survived to discharge, this therapy is not always futile. Prehospital emergency personnel need to be aware of possible hypoxic and electrical causes for cardiac arrest appearing in combination with traumatic injuries.     

Thrombolytics in CPR. Current advantages in cardiopulmonary resuscitation

Cardiac arrest carries a very poor prognosis. More than 70% of cardiac arrests are caused by acute myocardial infarction (AMI) or massive pulmonary embolism (PE). Thrombolysis during CPR has two major effects: first, it causally treats the condition that caused cardiac arrest and second, it has been shown to have beneficial effects on the microcirculatory cerebral reperfusion after cardiac arrest. However, this treatment has been widely withheld mainly because of the fear of severe bleeding complications. We reviewed the currently available in- and out-of-hospital studies on thrombolysis during CPR. Most studies found that thrombolytic therapy during CPR improves the chance for a restoration of spontaneous circulation in patients suffering from cardiac arrest and may even result in a better outcome. In addition, the neurological condition of surviving patients may be markedly improved by thrombolysis. Although thrombolytic therapy is associated with a risk of bleeding complications, currently available data do not suggest an increase of bleeding complications if thrombolysis is administered during CPR. Recently, a large randomized multicentre study has started to assess the efficacy and safety of thrombolysis during prehospital CPR.

Standardized documentation in emergency departments with the core dataset of the DIVI

In Germany the documentation of every prehospital emergency medical treatment has been standardized since 1997 based on the core data-set MIND (minimal emergency physician data-set). Against this background it is very surprising that there is still no standardized data-set implemented for the documentation of early inhospital emergency care. In order to create such a data-set the current state of documentation in many different hospitals all over the country was scrutinized. In addition existing registries and international requirements were taken into consideration. Finally, a modular data-set was created using a Delphi process. This data-set was tested, clinically validated and finally ratified by the executive committee of the DIVI (German Interdisciplinary Association of Critical Care Medicine). The modular data-set was designed in such a way that a basic module forms the foundation for every patient. Process-oriented modules (e.g. surveillance) and symptom-oriented modules (e.g. trauma, neurology) were added if necessary. Along with this data-set a set of six modules was created for graphical representation when required. This high level of standardization not only allows an internal and external quality assessment but also provides a sophisticated documentation system especially to the trauma team in the emergency department. In terms of content major parameters of interhospital quality management are recorded and important factors of process management, such as MTS (Manchester triage system), ATLS (advanced trauma life support) and EWS (early warning score) have been implemented. The data-set includes all necessary information for transfers between physicians and non-academic staff as well as between physicians and could also be used as a fundamental discharge letter. Moreover, this new core data-set is the implementation of items required by existing registries into the daily routine documentation in order to reduce unnecessarily time-consuming and error-prone secondary data acquisition. For example, all items of the preclinical and emergency room documentation for the TraumaRegister DGU? (documentation phase S, A and B of the standard and QM form) have been included. This is sufficient for participation as a TraumaNetzwerk DGU? member as far as the early clinical treatment of multiple injured patients is concerned.     

The prehospital management of hypothermia — An up-to-date overview

BackgroundAccidental hypothermia concerns a body core temperature of less than 35 °C without a primary defect in the thermoregulatory system. It is a serious threat to prehospital patients and especially injured patients, since it can induce a vicious cycle of the synergistic effects of hypothermia, acidosis and coagulopathy; referred to as the trauma triad of death. To prevent or manage deterioration of a cold patient, treatment of hypothermia should ideally begin prehospital. Little effort has been made to integrate existent literature about prehospital temperature management. The aim of this study is to provide an up-to-date systematic overview of the currently available treatment modalities and their effectiveness for prehospital hypothermia management.Data sourcesDatabases PubMed, EMbase and MEDLINE were searched using the terms: “hypothermia”, “accidental hypothermia”, “Emergency Medical Services” and “prehospital”. Articles with publications dates up to October 2017 were included and selected by the authors based on relevance.ResultsThe literature search produced 903 articles, out of which 51 focused on passive insulation and/or active heating. The most effective insulation systems combined insulation with a vapor barrier. Active external rewarming interventions include chemical, electrical and charcoal-burning heat packs; chemical or electrical heated blankets; and forced air warming. Mildly hypothermic patients, with significant endogenous heat production from shivering, will likely be able to rewarm themselves with only insulation and a vapor barrier, although active warming will still provide comfort and an energy-saving benefit. For colder, non-shivering patients, the addition of active warming is indicated as a non-shivering patient will not rewarm spontaneously. All intravenous fluids must be reliably warmed before infusion.ConclusionAlthough it is now accepted that prehospital warming is safe and advantageous, especially for a non-shivering hypothermic patient, this review reveals that no insulation/heating combinations stand significantly above all the others. However, modern designs of hypothermia wraps have shown promise and battery-powered inline fluid warmers are practical devices to warm intravenous fluids prior to infusion. Future research in this field is necessary to assess the effectiveness expressed in patient outcomes.     

Prehospital care in patients with severe traumatic brain injury: does the level of prehospital care influence mortality?

Introduction and purpose

The controversy between the “scoop and run” versus the “stay and play” approach in severely injured trauma patients has been an ongoing issue for decades. The present study was undertaken to investigate whether changes in prehospital care for patients with severe traumatic brain injury in the Netherlands have improved outcome.

Methods

In this retrospective study, files (n = 60) were analyzed from a prospectively collected database including all patients admitted to one of six hospitals in the Limburg region in the Netherlands with a Glasgow Coma Scale (GCS) score ≤8 on admittance over the period from January 2006 to December 2008. All patients had traumatic brain damage proven on computed tomography (CT) or magnetic resonance imaging (MRI). Relevant prehospital and clinical data from the present cohort were compared to data from a similar study (n = 30) conducted 20 years ago. The primary outcome assessed was mortality.

Results

The two study groups had similar characteristics with regard to the GCS score. In the historic cohort, Basic Life Support (BLS) and the “scoop and run” approach in patients with major traumatic brain injury was common, with an average time on scene of 7.5 min. Currently, prehospital care is performed mainly on the level of prehospital Advanced Life Support (ALS), with the average time on scene being about four times as long as in the historic cohort. However, the overall mortality rate for the current cohort compared to the historic cohort has not changed.

Conclusion

Despite more on-site ALS in severely head injured patients nowadays compared to the historic cohort, there was no reduction in mortality.     

Inflammatory response after out-of-hospital cardiac arrest—Impact on outcome and organ failure development

Background

Post-cardiac arrest syndrome that occurs in out-of-hospital cardiac arrest (OHCA) patients is characterized by inflammatory response. We conducted a scoping review of current evidence regarding several inflammatory markers' usefulness for assessment of patient outcome and illness severity. We also discuss the proposed underlying mechanisms leading to inflammatory response after OHCA.

Methods

We searched the MEDLINE, PubMed Central, Cochrane CENTRAL and Web of Science Core Collection databases with the following search terms: (“inflammation” OR “cytokines”) AND “out-of-hospital cardiac arrest.” Each inflammatory marker found was combined with “out-of-hospital cardiac arrest” using “AND” to find further relevant studies. We included original studies measuring inflammatory markers in adult OHCA patients that assessed their prognostic capabilities for mortality, neurological outcome, or organ failure severity.

Results

Fifty-nine studies met the inclusion criteria, covering in total 65 different markers. Interleukin-6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP) were the most studied markers, and they were associated with poor outcomes in 13/15, 13/14 and 11/17 studies, respectively. Based on area under the receiver operating characteristic curve (AUC) value, the time point of best discriminatory capacity for poor outcome was ICU admission for IL-6 (median AUC 0.78, range 0.71–0.98) and day one after OHCA for PCT (median AUC 0.84, range 0.61–0.98). Seven studies reported AUCs for CRP (range 0.52–0.76) with no measurement time point being superior to others. The association of IL-6 and PCT with outcome appeared stronger in studies with more severely ill patients. Studies reported conflicting results regarding each marker's association with organ failure severity.

Conclusion

Inflammatory markers are potentially useful for early risk stratification after OHCA. PCT and IL-6 have moderate prognostic value during the first 24 h of the ICU stay. Predictive accuracy appears to be associated with the study overall event rate.     

Cardiac arrest in France: Why a national register?

Cardiac arrest is a public health issue for which international guidelines are updated every five years (last bringing up to date on 2010 october). The lake of epidemiologic data on cardiac arrest justifies the building of a national register. French SAMU experienced registers especially in the field of acute coronary syndrom. Our national register "RéAC"is planned to deploy the present year for out-of-hospital cardiac arrest with the help of our scientific societies and the Department of Health. It is integrated in a program of evaluation and improvement of professional practices for physicians and prehospital teams who will be involved in its exhaustive use.     

Joint Position Paper of the Working Group of Pacing and Electrophysiology of the French Society of Cardiology (SFC) and the Société française d’imagerie cardiaque et vasculaire diagnostique et interventionnelle (SFICV) on magnetic resonance imaging in patients with cardiac electronic implantable devices

Magnetic resonance imaging (MRI) has become the reference imaging for the management of a large number of diseases. The number of MR examinations increases every year, simultaneously with the number of patients receiving a cardiac electronic implantable device (CEID). A CEID was considered an absolute contraindication for MRI for years. The progressive replacement of conventional pacemakers and defibrillators by MR-conditional CEIDs and recent data on the safety of MRI in patients with “MR-nonconditional” CEIDs have progressively increased the demand for MRI in patients with a CEID. However, some risks are associated with MRI in CEID carriers, even with “MR-conditional” devices because these devices are not “MR-safe”. A specific programing of the device in “MR-mode” and monitoring patients during MRI remain mandatory for all patients with a CEID. A standardized patient workflow based on an institutional protocol should be established in each institution performing such examinations. This joint position paper of the Working Group of Pacing and Electrophysiology of the French Society of Cardiology and the Société française d’imagerie cardiaque et vasculaire diagnostique et interventionnelle (SFICV) describes the effect and risks associated with MRI in CEID carriers. We propose recommendations for patient workflow and monitoring and CEID programming in MR-conditional, “MR-conditional nonguaranteed” and MR-nonconditional devices.     

Ein weiterer Fall von „Lazarus-Phänomen“?

The “Lazarus phenomenon” describes the spontaneous resumption of respiration and circulation after cardiac arrest has occurred which could not be reversed by emergency medical procedures. This phenomenon can by all means acquire forensic relevance. This contribution presents a case of possible Lazarus phenomenon that recently occurred in Hamburg. Based on this event, the problems involved in determining death during EMS deployment are discussed. It becomes apparent that such guidelines are lacking that are both explicit and practicable at the scene for declaring death during EMS missions. Cessation of resuscitation attempts when the EKG exhibits no activity should definitely be documented accordingly. The “provisional death certificate” introduced in Hamburg makes it possible to certify death during the rescue operation, and the mandatory autopsy is then performed in the Institute of Forensic Medicine. In view of the problems inherent in apparent death and the Lazarus phenomenon, the autopsy should be performed as promptly as possible.
