RESUMO
Currently arbitrary, inconsistent and non-evidence-based age cutoffs are used in the literature to classify pediatric emergencies. None of these classifications have valid medical rationale. This leads to confusion and poor comparability of the different study results. To clarify this problem, this paper presents a systematic review of the commonly used age limits from 115 relevant articles. In the literature search 6226 articles were screened. To be included, the articles had to address the following three topics: "health services research in emergency medicine", "pediatrics" and "age as a differentiator". Physiologic and anatomic principles with reference to emergency medicine were used to solve the problem to create a medically based age classification for the first time.The Munich Age Classification System (MACS) presented in this paper is thus consistent with previous literature and is based on medical evidence. In the future, MAC should lead to ensure that a uniform classification is used. This will allow a better comparability of study results and enable meta-analyses across studies.

BACKGROUND: The use of the emergency medical services (EMS) in Bavaria has been increasing for years. We hypothesized that emergency response without patient transport (RoT) is often an expression of inadequate alert planning. The aim of the study was to describe the differences between the integrated dispatch centers (ILSs) for such operations with regard to the characteristics of transport quotas and ranges according to the reason for deployment as well as times and days of the week. METHOD: Retrospective cross-sectional study of data from all 26 ILSs in the Free State of Bavaria in 2018. Transport quotas for emergency operations for essential reasons without emergency physician involvement were analyzed comparatively in relation to dispatch center area, time of day, and day of the week. Deployments were categorized as RoT or ambulance deployment with transport (TP). RESULTS: Of 510,145 call-outs, 147,621 (28.9%) were RoT and 362,524 (71.1%) were TP. There were significant regional differences in the transport quotas for all deployment reasons investigated. The highest range among the ILSs was found for the deployment reasons "fire alarm system" (16.8 percentage points), "personal emergency response system" (16.1%), and "heart/circulation" (14.6%). In the morning hours, the number of calls decreases with increasing TP. The fewest RoT took place between 8 and 10â¯am. The days of the week analysis revealed small differences in the frequency of RoT on Mondays as well as on weekends without planning relevance. CONCLUSION: We found significant differences in the ranges. This could indicate locally different alert planning specifications or dispatching decisions by the ILS. The control centers probably have considerable potential for controlling and improving resource allocation.

BACKGROUND: Mechanical chest compression (mCPR) offers advantages during transport under cardiopulmonary resuscitation. Little is known how devices of different design perform en-route. Aim of the study was to measure performance of mCPR devices of different construction-design during ground-based pre-hospital transport. METHODS: We tested animax mono (AM), autopulse (AP), corpuls cpr (CC) and LUCAS2 (L2). The route had 6 stages (transport on soft stretcher or gurney involving a stairwell, trips with turntable ladder, rescue basket and ambulance including loading/unloading). Stationary mCPR with the respective device served as control. A four-person team carried an intubated and bag-ventilated mannequin under mCPR to assess device-stability (displacement, pressure point correctness), compliance with 2015 ERC guideline criteria for high-quality chest compressions (frequency, proportion of recommended pressure depth and compression-ventilation ratio) and user satisfaction (by standardized questionnaire). RESULTS: All devices performed comparable to stationary use. Displacement rates ranged from 83% (AM) to 11% (L2). Two incorrect pressure points occurred over 15,962 compressions (0.013%). Guideline-compliant pressure depth was > 90% in all devices. Electrically powered devices showed constant frequencies while muscle-powered AM showed more variability (median 100/min, interquartile range 9). Although physical effort of AM use was comparable (median 4.0 vs. 4.5 on visual scale up to 10), participants preferred electrical devices. CONCLUSION: All devices showed good to very good performance although device-stability, guideline compliance and user satisfaction varied by design. Our results underline the importance to check stability and connection to patient under transport.

Medical care provided at the hospital emergency rooms in Germany has hardly been explored. On the occasion of restructuring the Municipal Hospital, the Munich City Council initiated the "Round Table Emergency Care" in order to determine reference figures for capacity planning. The present study was designed to analyze treatment data from 14 emergency departments which mainly carry the city's hospital emergency service. For inpatient cases, data were used in accordance with §21 Hospital Charges Act, for outpatient cases - as far as available - similar data were used, anonymized and combined with data from prehospital emergency medical services (EMS). In order to describe the domains treatment urgency, diagnostic/therapeutic effort and bed requirements, data were categorized in a 4-stage system. Over 12 months, 524,716 treatment cases were recorded: 34% were admitted to hospital, 80% came without EMS. One in 7 patients who independently went to an emergency room needed a bed in the intensive care or intermediate care unit (ICU/IMC). There were 64 cases per day and per 100,000 inhabitants requiring 7 ICU/IMC and 15 regular ward beds. Most cases (66%) were treated as outpatients and presented to the hospital's emergency department at times when facilities of the ambulatory care system would have been available. Urgency of these cases was usually low (50.9%), but effort was often high, due to diagnostics and surgical procedures. This study offers fundamental knowledge for planning emergency care. A large proportion of the presentations, especially those with injuries and those with diagnosis that require a more differentiated work-up, seem to be medically justified, which is why appropriate capacities have to be planned in. The study also shows that capacity planning on the basis of EMS cases alone is an inappropriate, one-sided approach.

We present a new method for estimating a change point in the hazard function of a survival distribution assuming a constant hazard rate after the change point and a decreasing hazard rate before the change point. Our method is based on fitting a stump regression to p values for testing hazard rates in small time intervals. We present three real data examples describing survival patterns of severely ill patients, whose excess mortality rates are known to persist far beyond hospital discharge. For designing survival studies in these patients and for the definition of hospital performance metrics (e.g. mortality), it is essential to define adequate and objective end points. The reliable estimation of a change point will help researchers to identify such end points. By precisely knowing this change point, clinicians can distinguish between the acute phase with high hazard (time elapsed after admission and before the change point was reached), and the chronic phase (time elapsed after the change point) in which hazard is fairly constant. We show in an extensive simulation study that maximum likelihood estimation is not robust in this setting, and we evaluate our new estimation strategy including bootstrap confidence intervals and finite sample bias correction.

BACKGROUND: Trauma team activation (TTA) represents a considerable expenditure of trauma centre resources. It is mainly triggered by field triage criteria. The overall quality of the criteria may be evaluated based on the rate of over- and undertriage. However, there is no gold standard that defines which adult patients truly require a trauma team. The objective of this study was to develop consensus-based criteria defining the necessity for a trauma team. METHODS: A consensus group was formed by trauma specialists experienced in emergency and trauma care with a specific interest in field triage and having previously participated in guideline development. A literature search was conducted to identify criteria that have already been used or suggested. The initial list of criteria was discussed in two Delphi round and two consensus conferences. The entire process of discussion and voting was highly standardized and extensively documented, resulting in a final list of criteria. RESULTS: Initially 95 criteria were identified. This was subsequently reduced to 20 final criteria to appropriately indicate the requirement for attendance of a trauma team. The criteria address aspects related to injury severity, admission to an intensive care unit, death within 24 h, need for specified invasive procedures, need for surgical and/or interventional radiological procedures, and abnormal vital signs within a defined time period. CONCLUSIONS: The selected criteria may be applied as a tool for research and quality control concerning TTA. However, future studies are necessary to further evaluate for possible redundancy in criteria that may allow for further reduction in criteria.

PURPOSE: U-shaped sacral fractures are extremely rare injuries that usually occur as a result of falls from considerable heights. Almost all treatment methods described to date aim solely at stabilizing the fracture but do not contribute to supporting the reduction of such fractures. Using existing implants the purpose of this study is to present a surgical technique that facilitates both the reduction and the stabilization of these injuries. The presented technique was evaluated in a series of three cases. METHODS: Polyaxial pedicle screws were placed through vertebral bodies L4 and L5. Two long pedicle screws were implanted in the posterior iliac spine. The lumbar pedicle screws were held with two longitudinal rods, and the pelvic screws with one transverse connecting rod. The lumbar longitudinal and pelvic transverse rods were connected via two hinge-like connecting elements. First, distraction was performed between lumbar pedicle screws L5 and the sacral transverse rod. Lordosis was then restored via the hinge joint, thereby eliminating kyphosis. After tightening all moving elements, the fracture was reduced and stabilized. RESULTS: Computed tomography documented anatomical reduction and fracture healing was achieved in all cases. Two of three patients could be fully mobilized immediately; mobilization of the third patient was delayed due to multiple injuries. Two patients showed neurological symptoms. In one case, complete remission was achieved within 3 weeks, while in the other patient a clear improvement was observed. In all cases, the implant was removed after 8-12 months. There were no post-operative complications, such as infections, wound-healing disorders, neurological deterioration, implant failure, or premature loosening. CONCLUSIONS: The surgical procedure was successful, since it considerably facilitated reduction, thereby shortening surgery time. The stabilization was sufficient to fully mobilize the patients. The procedure is based on existing implant components and is thus routinely available.

OBJECTIVE: Analyze sex differences in TraumaRegister DGU (TR-DGU). BACKGROUND: Sex differences are considered to influence trauma outcomes. However, clinical study results are controversial. METHODS: Of 29,353 prospectively recorded cases of TR-DGU, we included primary trauma room admissions with Injury Severity Score of 9 or more into the analysis. Pairs (n = 3887) were formed from 1 male and 1 female according to age, mechanism, injury severity by Abbreviated Injury Scale (for head, thorax, abdomen, extremities), and occurrence of prehospital shock. Biochemical markers, treatment modalities, length of stay, and outcome (multiple organ failure, sepsis, mortality rates) were assessed. Statistical significance was accepted at P < 0.05. Odds ratios (ORs) are given with 95% confidence interval (CI). RESULTS: Females had less multiple organ failure [OR: 1.18 (95% CI, 1.05-1.33); P = 0.007], particularly in age group of 16 to 44 years; sepsis [OR: 1.45 (95% CI, 1.21-1.74); P < 0.001]), particularly at age more than 45 years; and mortality [OR: 1.14 (95% CI, 1.01-1.28); P = 0.037]. Prehospital chest tube insertions (214 vs 158) and surgical procedures before intensive care unit admission were more often performed in males (79.7% vs 76.4%). Females had lower mean hemoglobin levels [10.7 ± 2.6 vs 11.9 ± 2.8 (mg/dL)]. There were no sex differences in fluid resuscitation, shock index, coagulation, and base excess. CONCLUSIONS: Males are more susceptible to multiple organ failure, sepsis, and mortality after trauma. Differences were not exclusively related to reproductive age and thus cannot be attributed to sex hormones alone. Females aged 16 to 44 years seem to tolerate shock better. Higher susceptibility to sepsis might be explained by male immune function or increased systemic burden from higher rates of surgical interventions.

PURPOSE: Advanced Trauma Life Support (ATLS®) is one of the world's best-known training programs for medical providers. Revisions of the ATLS manual have been evidence based for a number of years. In 2011, a level 3 (S3) evidence- and consensus-based guideline on the treatment of patients with severe and multiple injuries was published in Germany. The scope of this study was the systematic comparison of the educational content of the ATLS concept and the interdisciplinary "S3 polytrauma guideline." METHODS: A total of 123 key recommendations of the guideline were compared with the content of the ATLS manual (9th edition). Depending on the level of agreement, the recommendations were classed in the following categories: (1) Agreement. (2) Minor variation. (3) Major variation. RESULTS: An overall 86% conformity was found between the key recommendations of the guideline and the ATLS® manual. The ATLS® primary survey (ABCDE) showed an 85% conformity. The degree of conformity for the individual priorities was as follows: A (Airway) 79%, B (Breathing) 79%, C (Circulation) 86%, D (Disability) 93%, E (Exposure) 100%. The ATLS® secondary survey showed a 94% conformity. The main differences were in the areas of anesthetic induction, fluid administration, and coagulation therapy. CONCLUSIONS: According to our comparison, the educational content and manual of the ATLS are largely compatible with a high level of evidence S3 guideline. However, subsequent editions of both the ATLS® and the S3 guideline should re-examine and reassess a number of aspects.

Nausea and vomiting are frequent symptoms in emergency medicine and require a targeted drug intervention. Despite known disadvantages in terms of efficacy and side effects, metoclopramide is still often used in the emergency medical service to treat nausea and vomiting. Recent studies show that, especially in the therapy of opioid-triggered vomiting, metoclopramide is not significantly effective when compared to placebo. Dimenhydrinate seems to be an effective drug for various forms of nausea, but can often be relatively or absolutely contraindicated in emergency medicine due to its sedative effect. Based on a literature review, 5-HT3-antagonists appear to be a good alternative for the treatment of emesis in the emergency service. However, as for all antiemetics, the maximum dosage and potential side effects need to be paid attention to. In addition, neither of the 5-HT3-antagonists are approved for therapy of non-chemotherapy-induced vomiting or PONV. In conclusion, it may be considered to include 5-HT3-antagonists in addition to dimenhydrinate in the ambulance medical equipment. The routine use of a specific antiemetic is not recommended.

PURPOSE: Our aim was to review and update the existing evidence-based and consensus-based recommendations for the management of chest injuries in patients with multiple and/or severe injuries in the prehospital setting. This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries. METHODS: MEDLINE and Embase were systematically searched to May 2021. Further literature reports were obtained from clinical experts. Randomised controlled trials, prospective cohort studies, cross-sectional studies, and comparative registry studies were included if they compared interventions for the detection and management of chest injuries in severely injured patients in the prehospital setting. We considered patient-relevant clinical outcomes such as mortality and diagnostic test accuracy. Risk of bias was assessed using NICE 2012 checklists. The evidence was synthesised narratively, and expert consensus was used to develop recommendations and determine their strength. RESULTS: Two new studies were identified, both investigating the accuracy of in-flight ultrasound in the detection of pneumothorax. Two new recommendations were developed, one recommendation was modified. One of the two new recommendations and the modified recommendation address the use of ultrasound for detecting traumatic pneumothorax. One new good (clinical) practice point (GPP) recommends the use of an appropriate vented dressing in the management of open pneumothorax. Eleven recommendations were confirmed as unchanged because no new high-level evidence was found to support a change. CONCLUSION: Some evidence suggests that ultrasound should be considered to identify pneumothorax in the prehospital setting. Otherwise, the recommendations from 2016 remained unchanged.
RESUMO
Background/Objective: This prospective, multicenter observational cohort study was carried out in 12 trauma centers in Germany and Switzerland. Its purpose was to evaluate the rate of undertriage, as well as potential consequences, and relate these with different Trauma Team Activation Protocols (TTA-Protocols), as this has not been done before in Germany. Methods: Each trauma center collected the data during a three-month period between December 2019 and February 2021. All 12 participating hospitals are certified as supra-regional trauma centers. Here, we report a subgroup analysis of undertriaged patients. Those included in the study were all consecutive adult patients (age ≥ 18 years) with acute trauma admitted to the emergency department of one of the participating hospitals by the prehospital emergency medical service (EMS) within 6 h after trauma. The data contained information on age, sex, trauma mechanism, pre- and in-hospital physiology, emergency interventions, emergency surgical interventions, intensive care unit (ICU) stay, and death within 48 h. Trauma team activation (TTA) was initiated by the emergency medical services. This should follow the national guidelines for severe trauma using established field triage criteria. We used various denominators, such as ISS, and criteria for the appropriateness of TTA to evaluate the undertriage in four groups. Results: This study included a total of 3754 patients. The average injury severity score was 5.1 points, and 7.0% of cases (n = 261) presented with an injury severity score (ISS) of 16+. TTA was initiated for a total of 974 (26%) patients. In group 1, we evaluated how successful the actual practice in the EMS was in identifying patients with ISS 16+. The undertriage rate was 15.3%, but mortality was lower in the undertriage cohort compared to those with a TTA (5% vs. 10%). In group 2, we evaluated the actual practice of EMS in terms of identifying patients meeting the appropriateness of TTA criteria; this showed a higher undertriage rate of 35.9%, but as seen in group 1, the mortality was lower (5.9% vs. 3.3%). In group 3, we showed that, if the EMS were to strictly follow guideline criteria, the rate of undertriage would be even higher (26.2%) regarding ISS 16+. Using the appropriateness of TTA criteria to define the gold standard for TTA (group 4), 764 cases (20.4%) fulfilled at least one condition for retrospective definition of TTA requirement. Conclusions: Regarding ISS 16+, the rate of undertriage in actual practice was 15.3%, but those patients did not have a higher mortality.
RESUMO
BACKGROUND AND IMPORTANCE: The COVID-19 pandemic affected the utilization of health care services and posed organizational challenges. While many previous studies focused on the misuse of pre-hospital EMS for low-urgency health problems, the pandemic has put more emphasis on the avoidance of medically necessary calls. OBJECTIVE: To compare the utilization of pre-hospital emergency medical services before and after specific pandemic periods. DESIGN, SETTING AND PARTICIPANTS: This was a retrospective, descriptive analysis of routine data from 26 dispatch centers in Bavaria, Germany. OUTCOMES MEASURE AND ANALYSIS: We investigated the number of emergencies per 100,000 population, as well as the relative change in the emergency rates and transport rates in 2020, compared to the two previous years. Boxplots showed the distributions across the Bavarian districts per calendar week. The mean rates and standard deviations as well as the relative changes were presented for the specific periods. A paired samples t-test was used to compare the rates. MAIN RESULTS: Compared to the average of the two previous years, the emergency rates in 2020 were lower in 35 out of 52 calendar weeks. The strongest reductions were observed during the first wave, where the average emergency rate declined by 12.9% (SD 6.8, p < 0.001). There was no statistically significant difference in the overall emergency rate during the summer holidays. Lower transport rates were observed throughout the year, especially during the first wave. CONCLUSIONS: Utilization of pre-hospital emergency medical services decreased in 2020, especially during the periods with strict measures. This could be due to the lower morbidity from the behavioral changes during the pandemic, but also to the avoidance of medical services for both less urgent and severe conditions. While a reduction in unnecessary care would be beneficial, patients must be encouraged to seek necessary urgent care, even during a pandemic.
RESUMO
BACKGROUND: To date, no detailed analysis of pediatric emergencies treated in emergency departments (ED) exists. However, in the context of capacity planning and upcoming emergency care reform in Germany, these data are urgently needed. METHODS: Retrospective, multicenter cross-sectional study for the period 01 July 2013 to 01 June 2014 of pediatric cases in emergency departments in Munich. RESULTS: A total of 103,830 cases were analyzed (age: 6.9⯱ 5.4 years, boys/girls 55%/45%). A total of 85.9% of cases were treated as outpatients, 12.4% (9.6 per 100,000 children) were admitted to normal and 1.7% (1.0 per 100,000 children) to intensive care. However, the real bed requirements exceeded these guideline numbers, with an absolute requirement of 4.9 ICU beds and 35.1 normal ward beds per day. Load peaks were seen on Wednesday and Friday afternoons and on weekends. Every 8th patient who presented to an ED as a self-referral was treated as an inpatient. CONCLUSION: Capacity planning for inpatient emergency care of pediatric patients requires planning for more beds than can be expected on a population basis. The availability of panel physician care influences patient volume in the EDs. Initial medical assessment tools for treatment need and urgency are needed to distribute patients. The pediatric emergency centers planned as part of the current reform of emergency care must be adequately staffed and financed in order to be able to handle-in close cooperation with statutory health insurance-accredited medical care-the expected demand for care.
RESUMO
BACKGROUND: Checklists are a powerful tool for reduction of mortality and morbidity. Checklists structure complex processes in a reproducible manner, optimize team interaction, and prevent errors related to human factors. Despite wide dissemination of the checklist, effects of checklist use in the prehospital emergency medicine are currently unclear. The aim of the study was to demonstrate that participants achieve higher adherence to guideline-recommended actions, manage the scenario more time-efficient, and thirdly demonstrate better adherence to the ABCDE-compliant workflow in a simulated ROSC situation. METHODS: CHIPS was a prospective randomized case-control study. Professional emergency medical service teams were asked to perform cardiopulmonary resuscitation on an adult high-fidelity patient simulator achieving ROSC. The intervention group used a checklist which transferred the ERC guideline statements of ROSC into the structure of the 'ABCDE' mnemonic. Guideline adherence (performance score, PS), utilization of process time (items/minute) and workflow were measured by analyzing continuous A/V recordings of the simulation. Pre- and post-questionnaires addressing demographics and relevance of the checklist were recorded. Effect sizes were determined by calculating Cohen's d. The level of significance was defined at p < 0.05. RESULTS: Twenty scenarios in the intervention group (INT) and twenty-one in the control group (CON) were evaluated. The average time of use of the checklist (CU) in the INT was 6.32 min (2.39-9.18 min; SD = 2.08 min). Mean PS of INT was significantly higher than CON, with a strong effect size (p = 0.001, d = 0.935). In the INT, significantly more items were completed per minute of scenario duration (INT, 1.48 items/min; CON, 1.15 items/min, difference: 0.33/min (25%), p = 0.001), showing a large effect size (d = 1.11). The workflow did not significantly differ between the groups (p = 0.079), although a medium effect size was shown (d = 0.563) with the tendency of the CON group deviating stronger from the ABCDE than the INT. CONCLUSION: Checklists can have positive effects on outcome in the prehospital setting by significantly facilitates adherence to guidelines. Checklist use may be time-effective in the prehospital setting. Checklists based on the 'ABCDE' mnemonic can be used according to the 'do verify' approach. Team Time Outs are recommended to start and finish checklists.

BACKGROUND: The decision of the Federal Joint Committee has resulted in the further development of in-hospital emergency medicine through the establishment of central emergency departments and staged emergency care. In addition, the additional training in clinical acute and emergency medicine was established. AIM: The aim of this work is on the one hand to make trauma surgeons aware of these structural changes. On the other hand, we would like to evaluate an opinion and discuss the position of trauma surgery in emergency medicine. METHODS: A web-based online survey was conducted at the Trauma Network and Trauma Registry Congress to collect participants' opinions on the position of trauma surgery in emergency medicine. RESULTS: Of 143 congress participants, 98 (67%) responded to the survey. The majority of participants were male (nâ¯= 78, 80%), over 40 years of age (nâ¯= 62, 63%), and in a professional position with staff responsibility (nâ¯= 73, 75%). Emergency medicine (mean: 84.8; SD: 18.7) and intensive care medicine (mean: 78.3; SD: 20.4) training appears important. On the other hand, subsequent work in these areas appears less important (prehospital emergency medicine: mean: 65.1; SD: 28.0; ICU: mean: 53.7, SD: 30.3); however, activity in an emergency department is rated higher (MW: 87.0; SD: 18.7). There is high agreement that the trauma leader should be a trauma surgeon (mean 87.9; SD: 19.7). DISCUSSION: A high volume of emergency trauma surgery patients and the care of severely injured patients in designated trauma centers show that trauma surgery expertise is mandatory in a central emergency department. Senior positions should also be sought to ensure high quality standards.

BACKGROUND: Not all patients who call the ambulance service are subsequently transported to hospital. In 2018, a quarter of deployments of an emergency ambulance in Bavaria were not followed by patient transport. This study describes factors that influence patient transport rates. METHOD: This is a retrospective cross-sectional study based on data from all Integrated Dispatch Centres of the Free State of Bavaria in 2018. Included were ambulance deployments without emergency physician involvement, which were subdivided into ambulance deployments without transport and ambulance deployments with transport. The proportion of transported patients were determined for the primary reasons for deployment and for the different community types. On-scene time was compared for calls with and without patient transport. Differences were tested for statistical significance using Chi2 tests and the odds ratio was calculated to determine differences between groups. RESULTS: Of 510,145 deployments, 147,621 (28.9%) could be classified as ambulance deployments without transport and 362,524 (71.1%) as ambulance deployments with transport.The lowest proportion of patients transported was found for activations where the fire brigade was involved ("fire alarm system" 0.6%, "fire with emergency medical services" 5.4%) and "personal emergency response system active alarm" (18.6%). The highest transport rates were observed for emergencies involving "childbirth/delivery" (96.9%) and "trauma" (83.2%). A lower proportion of patients is transported in large cities as compared to smaller cities or rural communities; in large cities, the odds ratio for emergencies without transport is 2.02 [95% confidence interval 1.98-2.06] referenced to rural communites. The median on-scene time for emergencies without transport was 20.8 min (n = 141,052) as compared to 16.5 min for emergencies with transport (n = 362,524). The shortest on-scene times for emergencies without transport were identified for activations related to "fire alarm system" (9.0 min) and "personal emergency response system active alarm" (10.6 min). CONCLUSION: This study indicates that the proportion of patients transported depends on the reason for deployment and whether the emergency location is urban or rural. Particularly low transport rates are found if an ambulance was dispatched in connection with a fire department operation or a personal emergency medical alert button was activated. The on-scene-time of the rescue vehicle is increased for deployments without transport. The study could not provide a rationale for this and further research is needed. Trial registration This paper is part of the study "Rettungswageneinsatz ohne Transport" ["Ambulance deployment without transport"] (RoT), which was registered in the German Register of Clinical Studies under the number DRKS00017758.

Background: Trauma registries are a crucial component of trauma systems, as they could be utilized to perform a benchmarking of quality of care and enable research in a critical but important area of health care. The aim of this study is to compare the performance of two national trauma systems: Germany (TraumaRegister DGU®, TR-DGU) and Israel (Israeli National Trauma Registry, INTR). Methods: The present study was a retrospective analysis of data from the described above trauma registries in Israel and Germany. Adult patients from both registries treated during 2015-2019 with an Injury Severity Score (ISS) ≥ 16 points were included. Patient demographics, type, distribution, mechanism, and severity of injury, treatment delivered and length of stay (LOS) in the ICU and in the hospital were included in the analysis. Results: Data were available from 12,585 Israeli patients and 55,660 German patients. Age and sex distribution were comparable, and road traffic collisions were the most prevalent cause of injuries. The ISS of German patients was higher (ISS 24 vs. 20), more patients were treated on an intensive care unit (92 vs. 32%), and mortality was higher (19.4 vs. 9.5%) as well. Conclusion: Despite similar inclusion criteria (ISS ≥ 16), remarkable differences between the two national datasets were observed. Most probably, this was caused by different recruitment strategies of both registries, like trauma team activation and need for intensive care in TR-DGU. More detailed analyses are needed to uncover similarities and differences of both trauma systems.

INTRODUCTION: To improve the quality of criteria for trauma-team-activation it is necessary to identify patients who benefited from the treatment by a trauma team. Therefore, we evaluated a post hoc criteria catalogue for trauma-team-activation which was developed in a consensus process by an expert group and published recently. The objective was to examine whether the catalogue can identify patients that died after admission to the hospital and therefore can benefit from a specialized trauma team mostly. MATERIALS AND METHODS: The catalogue was applied to the data of 75,613 patients from the TraumaRegister DGU® between the 01/2007 and 12/2016 with a maximum abbreviated injury score (AIS) severity ≥ 2. The endpoint was hospital mortality, which was defined as death before discharge from acute care. RESULTS: The TraumaRegister DGU® dataset contains 18 of the 20 proposed criteria within the catalogue which identified 99.6% of the patients who were admitted to the trauma room following an accident and who died during their hospital stay. Moreover, our analysis showed that at least one criterion was fulfilled in 59,785 cases (79.1%). The average ISS in this group was 21.2 points (SD 9.9). None of the examined criteria applied to 15,828 cases (average ISS 8.6; SD 5). The number of consensus-based criteria correlated with the severity of injury and mortality. Of all deceased patients (8,451), only 31 (0.37%) could not be identified on the basis of the 18 examined criteria. Where only one criterion was fulfilled, mortality was 1.7%; with 2 or more criteria, mortality was at least 4.6%. DISCUSSION: The consensus-based criteria identified nearly all patients who died as a result of their injuries. If only one criterion was fulfilled, mortality was relatively low. However, it increased to almost 5% if two criteria were fulfilled. Further studies are necessary to analyse and examine the relative weighting of the various criteria. Our instrument is capable to identify severely injured patients with increased in-hospital mortality and injury severity. However, a minimum of two criteria needs to be fulfilled. Based on these findings, we conclude that the criteria list is useful for post hoc analysis of the quality of field triage in patients with severe injury.
