IntroductionPrevious studies reported divergent results concerning the effect of gender on patient outcome after severe injury. Results suggest that women have better outcomes because they have lower rates of sepsis and multi-organ failure. The objective of this analysis was to study gender differences in a Level 1 trauma center in Germany.MethodsPatients who were admitted to hospital between 2002 and 2011 with an Injury Severity Score (ISS) ≥16 were included. Data were collected from the Trauma Registry of the German Society for Trauma Surgery and from hospital records. The effects of gender on a variety of parameters were investigated. To eliminate the influence of differences in ISS, an analysis of groups with similar ISS was performed. Also, a matched-pair analysis of 422 patients was performed.ResultsA total of 962 patients met the inclusion criteria. The mortality rate was lower in male patients (25.4% versus 36.59%). Female patients had more severe head injuries, received less fluid volume and had a lower rate of sepsis. Men were more frequently involved in motorcycle accidents and sustained more penetrating trauma. Women were more frequently involved in pedestrian accidents and sustained more falls from under 3 m. The effects of gender were reduced when the data were analyzed by matching ISS. The mortality rate was significantly different in the ISS 26 to 35 group but in mostly all groups, the mortality rate was higher in women. In the matched-pair analysis, the rate of sepsis and the length of the ICU stay were significantly lower in women and the mortality rate showed no significant difference (28.1% for male patients versus 33.01% for female patients). Women died after an average of 5.22 days, and men died after an average of 9.02 days.ConclusionsGender-based differences in patient outcome after severe trauma were observed in this study. Women are more likely to die in the first days after trauma. Upon extended hospital stay, women had a better survival rate because they had a lower rate of sepsis. No significant differences in mortality rate could be found, but there was a trend towards a higher rate in female patients.

BackgroundTrauma in pediatric patients is a major cause of death. This study investigated differences between decedents and survivors. Furthermore, an analysis of preventable and potential preventable trauma deaths was conducted and errors in the acute trauma care were investigated.MethodsAll patients aged less than 16 years with an Injury Severity Score (ISS) ≥ 16 upon primary admission to the hospital between July 2002 and December 2011 were included in this study. Decedents were compared with survivors and an analysis of deceased children for preventable and potential preventable deaths was conducted. The acute trauma care was investigated regarding errors in treatment.ResultsSignificant differences were found in Glasgow Coma Scale, Injury Severity Score, Revised Trauma Score, New ISS, Revised Injury Severity Classification, and Trauma and Injury Severity Score. Decedents had a worse head trauma with associated coagulopathy. The overall mortality rate was 13.4%. The majority of death occurred soon after arrival. No long term intensive care unit stay was found.No preventable but one potential preventable death was analyzed. Most errors occurred in fluid volume management and in a delay of starting the therapy for hemorrhage and coagulopathy.Prolonged preclinical rescue time and surgery time within the first 24 hours was found.ConclusionsHead trauma is the determinant factor for mortality in severely injured pediatric patients. Death occurred shortly after arrival and long term intensive care stays might be an exception. In treatment of severely injured children volume management, hemorrhage and coagulopathy management, rescue time, and total surgery time should receive more attention.

Preventable and potentially preventable errors still occur in the treatment of severely injured patients. Errors in hemorrhage control and airway management are the most common human treatment errors. The knowledge of these errors could help to improve trauma care in the future.

IntroductionTraumatic injuries are amongst the leading causes of death worldwide, frequently as a result of uncontrolled hemorrhage. Critical deficiencies in clotting factors have been noted in trauma-induced coagulopathy. However, the exact underlying conditions that result in devastating coagulopathies remain unclear. The purpose of this study was to elucidate these underlying deficiencies.MethodsBlood samples were drawn from 45 severely injured trauma patients on their arrival at the resuscitation room, and the activities of all soluble clotting factors and routine coagulation tests were assessed. The Mann–Whitney-U-test was used to assess differences in coagulation activity between the patients and healthy controls. Furthermore, Spearman’s rank correlation was used to analyze the blood work.ResultsAfter severe trauma the levels of serum fibrinogen and calcium were significantly reduced. Furthermore, traumatized patients had a significantly increased International Normalized Ratio (INR) compared to healthy controls. The median activities of all clotting factors were reduced after severe multiple trauma, with the exception of factor VIII, which was increased. Statistically significant differences were observed for factors II (80 vs. 122 %, P < 0.0001), V (76 vs. 123 %, P < 0.0001), VII (90 vs. 114 %, P = 0.002), VIII (200 vs. 108 %, P < 0.0001), and X (86 vs. 122 %, P < 0.0001). Spearman’s correlation indicated a significant negative correlation between INR on arrival with fibrinogen and levels of factors II, V, and VII, whereas Partial Thromboplastin Time was significantly negatively correlated with factor VIII (all P < 0.0001).ConclusionsThese findings suggest a general but rather moderate impairment of clotting factor activities following severe multiple trauma. In the concept of a calculated coagulation therapy, this could demand for the use of factor concentrates with higher ratios of clotting factors. Finally, the physiological importance of strongly elevated factor VIII activity remains unclear, but a possible interference with ex vivo measurements of Partial Thromboplastin Time has to be considered.

Background. Prehospital volume therapy remains widely used after trauma, while evidence regarding its disadvantages is growing. The primary objective of this study was to investigate the volume administered in a prehospital setting as an independent risk factor for mortality. Material and Methods. Patients who met the following criteria were analyzed retrospectively: Injury Severity Score = 16, primary admission (between 2002 and 2010), and age = 16 years. The following data had to be available: volume administered (including packed red cells), blood pressure, Glasgow Coma Scale, therapeutic measures, and laboratory results. Following a univariate analysis, independent risk factors for mortality after trauma were investigated using a multivariate regression analysis. Results. A collective of 7,641 patients met the inclusion criteria, showing that increasing volumes administered in a prehospital setting were an independent risk factor for mortality (odds ratio: 1.34). This tendency was even more pronounced in patients without severe traumatic brain injury (TBI) (odds ratio: 2.71), while the opposite tendency was observed in patients with TBI. Conclusions. Prehospital volume therapy in patients without severe TBI represents an independent risk factor for mortality. In such cases, respiratory and circulatory conditions should be stabilized during permissive hypotension, and patient transfer should not be delayed.

Background The COVID 19 pandemic is a major challenge to all social systems, particularly the healthcare system. Within an international study, German Trauma Centres DGU and Geriatric Trauma Centres DGU have been questioned about their situation. Method The questionnaire was translated from English into German and sent to all contacts. The evaluation was performed descriptively. Results 71 of 692 centres participated in this study. Government instructions to avoid elective treatments have been adhered to by 68% of the hospitals, and the remaining performed only urgent elective treatments. There was also a decline in the number of traumatological patients. In more than 90% of the hospitals, only 0 – 4% of all patients treated for proximal femur fracture were tested positive for COVID-19. It appears that 84% of these hospitals have or will have financial deficits. Almost all hospitals were organised and ready to fight the pandemic with their personal and/or infrastructural resources they possess. Conclusion Our questionnaire shows that the pandemic had an enormous effect on Trauma Centres DGU and Geriatric Trauma Centres DGU. The hospitals expect financial losses. Almost all the hospitals have provided personal and infrastructural resources to be used in the fight against the pandemic with a better outcome in Germany in comparison with international standards.

BackgroundDemographic change is expected to result in an increase in cases of severely injured elderly patients. To determine special considerations in treatment and outcome, patients aged 75 years and older were studied.MethodsAll patients in the included age group with an Injury Severity Score (ISS) ≥ 16 upon primary admission to hospital between July 2002 and December 2011 were included in this mortality analysis. The data used for this study was gained partly from data submitted to the German Trauma Register and partly from patients’ hospital records. A comparison between survivors and decedents was performed, as well as age-adjusted and ISS-adjusted analyses. The odds ratio and relative risk were used to determine predictors for mortality.ResultsOne-hundred eight patients met the inclusion criteria. The overall mortality proportion was 57.4%. The decedents were more severely injured (ISS 26 vs. 20, p < 0.001) and suffered more severe head traumas (GCS 4 vs. 12, p < 0.001; AIS head 5 vs. 4, p = 0.006). No differences were found in vital parameters measured at the accident scene or trauma room. Decedents had deranged coagulation with a prolonged PTT (41.1 sec vs. 27.6 sec, p = 0.008) and reduced prothrombin ratio (66.5% vs. 82.8%, p = 0.016).Only 17.1% of patients presenting an ISS > 25 survived, suggesting that an injury of such severity is hardly survivable in the subject age group.Predictors for mortality were: ISS > 25, GCS < 9, PTT > 32.4 seconds, prothrombin ratio < 70%, AIS head > 3, and Hb < 12 g/dl.ConclusionsThe treatment of severely injured elderly patients is challenging. The most common cause of accident is falling from less than 3 m with head injuries being determinant. We identified deranged coagulopathy as an important predictor for mortality, suggesting rapid normalization of coagulation might be a key to reducing mortality.
