The morbidity and mortality of severely injured patients are commonly affected by multiple factors. Especially, severe chest trauma has been shown to be a significant factor in considering outcome. Contemporaneously, weight-associated endocrinological, haematological, and metabolic deviations from the norm seem to have an impact on the posttraumatic course. Therefore, the aim of this study was to determine the influence of body weight on severely injured patients by emphasizing chest trauma. A total of 338 severely injured patients were included. Multivariate regression analyses were performed on patients with severe chest trauma (AIS ≥ 3) and patients with minor chest trauma (AIS < 3). The influence of body weight on in-hospital mortality was evaluated. Of all the patients, 70.4% were male, the median age was 52 years (IQR 36–68), the overall Injury Severity Score (ISS) was 24 points (IQR 17–29), and a median BMI of 25.1 points (IQR 23–28) was determined. In general, chest trauma was associated with prolonged ventilation, prolonged ICU treatment, and increased mortality. For overweight patients with severe chest trauma, an independent survival benefit was found (OR 0.158; p = 0.037). Overweight seems to have an impact on the mortality of severely injured patients with combined chest trauma. Potentially, a nutritive advantage or still-unknown immunological aspects in these patients affecting the intensive treatment course could be argued.
miR-142-3p expression is predictive for severe traumatic brain injury (TBI) in trauma patients
(2020)
Background: Predictive biomarkers in biofluids are the most commonly used diagnostic method, but established markers in trauma diagnostics lack accuracy. This study investigates promisingmicroRNAs(miRNA)releasedfromaffectedtissueafterseveretraumathathavepredictive values for the effects of the injury.
Methods: A retrospective analysis of prospectively collected data and blood samples of n = 33 trauma patients (ISS≥16) is provided. Levels of miR-9-5p, -124-3p, -142-3p, -219a-5p, -338-3pand-423-3p inseverelyinjuredpatients (PT)withouttraumatic braininjury (TBI) or with severe TBI (PT + TBI) and patients with isolated TBI (isTBI) were measured within 6 h after trauma.
Results: The highest miR-423-3p expression was detected in patients with severe isTBI, followed by patients with PT + TBI, and lowest levels were found in PT patients without TBI (2−∆∆Ct,p = 0.009). ApositivecorrelationbetweenmiR-423-3plevelandincreasingAIShead (p = 0.001) and risk of mortality (RISC II, p = 0.062) in trauma patients (n = 33) was found. ROC analysis of miR-423-3p levels revealed them as statistically significant to predict the severity of brain injury in trauma patients (p = 0.006). miR-124-3p was only found in patients with severe TBI, miR-338-3p was shown in all trauma groups. miR-9-5p, miR-142-3p and miR-219a-5p could not be detected in any of the four groups. Conclusion: miR-423-3p expression is significantly elevated after isolated traumatic braininjuryandpredictableforsevereTBIinthefirsthoursaftertrauma. miR-423-3pcouldrepresent a promising new biomarker to identify severe isolated TBI.
The inflammatory response plays an important role in the pathophysiology of multiple injuries. This study examines the effects of severe trauma and inflammatory response on markers of neuronal damage. A retrospective analysis of prospectively collected data in 445 trauma patients (Injury Severity Score (ISS) ≥ 16) is provided. Levels of neuronal biomarkers (calcium-binding Protein B (S100b), Enolase2 (NSE), glial fibrillary acidic protein (GFAP)) and Interleukins (IL-6, IL-10) in severely injured patients (with polytrauma (PT)) without traumatic brain injury (TBI) or with severe TBI (PT+TBI) and patients with isolated TBI (isTBI) were measured upon arrival until day 5. S100b, NSE, GFAP levels showed a time-dependent decrease in all cohorts. Their expression was higher after multiple injuries (p = 0.038) comparing isTBI. Positive correlation of marker level after concomitant TBI and isTBI (p = 0.001) was noted, while marker expression after PT appears to be independent. Highest levels of IL-6 and -10 were associated to PT und lowest to isTBI (p < 0.001). In all groups pro-inflammatory response (IL-6/-10 ratio) peaked on day 2 and at a lower level on day 4. Severe TBI modulates kinetic profile of inflammatory response by reducing interleukin expression following trauma. Potential markers for neuronal damage have a limited diagnostic value after severe trauma because undifferentiated increase.
Background: Surgical complications are associated with a significant burden to patients and hospitals and are increasingly discussed in recent literature. This cohort study reviewed surgery-related complications in a Level I trauma center. The effect of a complication avoidance care bundle on the rate of surgical complications was analyzed. Methods: All complications (surgical and nonsurgical) that occur in our trauma department are prospectively captured using a standardized documentation form and are discussed and analyzed in a weekly trauma Morbidity and Mortality (M&M) conference. Surgical complication rates are calculated using the annual surgical procedure numbers. Based on discussions in the M&M conference, a complication avoidance care bundle consisting of five measures was established: (1) Improving team situational awareness; (2) reducing operating room traffic by staff members and limiting door-opening events; (3) preoperative screening for infectious foci; (4) adapted preoperative antibiotic prophylaxis in anatomic regions with a high risk of infectious complications; and (5) use of iodine-impregnated adhesive drape. Results: The number of surgical procedures steadily increased over the study years, from 3587 in 2015 to 3962 in 2019 (an increase of 10.5%). Within this 5-year study period, the overall rate of surgical complications was 0.8%. Surgical site infections were the most frequently found complications (n = 40, 24.8% of all surgical complications), followed by screw malposition (n = 20, 12.4%), postoperative dislocations of arthroplasties (n = 18, 11.2%), and suboptimal fracture reduction (n = 18, 11.2%). Following implementation of the complication avoidance care bundle, the overall rate of surgical complications significantly decreased, from 1.14% in the year 2016 to 0.56% in the study year 2019, which represents a reduction of 51% within a 3-year time period. Conclusions: A multimodal strategy targeted at reducing the surgical complication rate can be successfully established based on a transparent discussion of adverse surgical outcomes. The combination of the different preventive measures was associated with reducing the overall complication rate by half within a 3-year time period.
Background: The treatment of severely injured patients, especially in older age, is complex, and based on strict guidelines. Methods: We conducted a retrospective study by analyzing our internal registry for mortality risk factors in deceased trauma patients. All patients that were admitted to the trauma bay of our level-1-trauma center from 2014 to 2018, and that died during the in-hospital treatment, were included. The aim of this study was to carry out a quality assurance concerning the initial care of severely injured patients. Results: In the 5-year period, 135 trauma patients died. The median (IQR) age was 69 (38–83) years, 71% were male, and the median (IQR) Injury Severity Score (ISS) was 25 (17–34) points. Overall, 41% of the patients suffered from severe traumatic brain injuries (TBI) (AIShead ≥ 4 points). For 12.7%, therapy was finally limited owing to an existing patient’s decree; in 64.9% with an uncertain prognosis, a ‘therapia minima’ was established in consensus with the relatives. Conclusion: Although the mortality rate was primarily related to the severity of the injury, a significant number of deaths were not exclusively due to medical reasons, but also to a self-determined limitation of therapy for severely injured geriatric patients. The conscientious documentation concerning the will of the patient is increasingly important in supporting medical decisions.
Introduction: In patients with severe pelvic ring injuries, exsanguination still is the leading cause of death in the early post-injury phase. While mechanical pelvic ring stabilization and pre-peritoneal pelvic packing are mainly addressing venous bleeding, angio-embolization aims to control arterial bleeding. The goal of the present study was to evaluate the rate of postoperative angio-embolization after mechanical pelvic ring injury stabilization and pre-peritoneal pelvic packing. Bleeding sources detected in the angiography and the patient's outcome were investigated. Patients and Methods: Retrospective observational cohort study at a single academic level I trauma center, reviewing all patients with pelvic ring injuries admitted from 01/2010 to 12/2019. Patients with emergent mechanical pelvic ring stabilization (supraacetabular external fixator and/or pelvic C-clamp) and direct pre-peritoneal pelvic packing were further analyzed. Patients that underwent postoperative angio-embolization were compared with those that did not. All postoperative angio-embolizations were evaluated with regards to bleeding sources and type of embolization. Results: During the study period, a total of 39 patients required immediate mechanical pelvic stabilization and direct pre-peritoneal pelvic packing. Of these, 12 patients (30.8%) underwent a postoperative angio-embolization. The following vessels were identified as bleeding sources: superior gluteal artery (n = 6), obturator artery (n = 2), internal pudendal artery (n = 2), unnamed branches of the internal iliac artery (n = 3). A selective embolization was successful in 11 patients; in 1 patient, an unilateral complete occlusion of the internal iliac artery was performed to control the bleeding. Mean time from hospital admission to the surgical procedure was 52.8 ± 14.7 min and the mean time from admission to angio-embolization was 189.1 ± 55.5 min. The in-hospital mortality rate of patients with angio-embolization was 25.0% (n = 3). Of these, 2 patients died due to multiple organ failure and 1 patient due to severe head injury. Conclusion: Secondary angio-embolization after external pelvic fixation and pre-peritoneal pelvic packing was effective in controlling ongoing bleeding. The most frequently detected bleeding vessel was the superior gluteal artery, which is difficult to surgically address, further highlighting the importance of angio-embolization in the management algorithm.
Since the introduction of rental E-scooters in Germany in mid-June 2019, the safety of this new means of transport has been the subject of extensive public debate. However, valid data on injuries and usage habits are not yet available. This retrospective two-center study included a total of 76 patients who presented to the emergency department following E-scooter-related accidents. The mean age was 34.3 ± 12.4 years and 69.7% of the patients were male. About half of the patients were admitted by ambulance (42.1%). Fractures were found in 48.6% of patients, and 27.6% required surgical treatment due to a fracture. The upper extremities were the most commonly affected body region, followed by injuries to the lower extremity and to the head and face. Only one patient had worn a helmet. In-hospital treatment was necessary for 26.3% of the cases. Patients presented to the emergency department mainly during the weekend and on-call times. This is the first report on E-scooter-related injuries in Germany. Accidents with E-scooters can cause serious injuries and, therefore, represent a further burden to emergency departments. The use of E-scooters appears to be mostly recreational, and the rate of use of protective gear is low.
Hintergrund: Die Analyse krankheitsspezifischer Kosten gewinnt in einem zunehmend ökonomisch ausgerichteten Gesundheitssystem an Relevanz, wobei vor allem chronische Erkrankungen aufgrund der langen Krankheitsdauer sowie häufiger Hospitalisierung und Arztbesuche von besonderem Interesse sind. Epilepsien stellen eine häufige neurologische Erkrankung dar, welche mit paroxysmal auftretenden epileptischen Anfällen und häufig hiermit assoziierten Verletzungen einhergeht und alle Altersgruppen betrifft.
Ziel: Ziel der Arbeit ist die Aufarbeitung der stationären Behandlungskosten anfallsbedingter Verletzungen sowie die Analyse hinsichtlich relevanter kostenverursachender Faktoren. Mittels alternativer Kalkulation der Versorgungskosten soll zusätzlich der Frage nach potenziellen Vergütungsproblemen im aktuellen DRG-System („diagnosis related groups“) nachgegangen werden.
Methoden: Grundlage dieser monozentrischen, retrospektiven Analyse ist der tatsächliche Erlös der stationären Behandlung von 62 Patienten, die zwischen 01/2010 und 01/2018 im Universitätsklinikum Frankfurt aufgrund von Verletzungen im Rahmen epileptischer Anfälle erfolgte. Die Analyse potenzieller kostenverursachender Faktoren bezog sich auf relevante soziodemographische und klinische Aspekte, die alternative Kalkulation der Versorgungskosten wurde mit gängigen gesundheitsökonomischen Methoden durchgeführt.
Ergebnisse: Der mittlere DRG-Erlös betrug 7408 € (±8993 €, Median 5086 €, Spanne 563–44.519 €), die mittleren kalkulierten Kosten 9423 € (±11.113 €, 5626 €, Spanne 587–49.830 €). Als signifikant kostenverursachender Faktor konnte eine Liegedauer ≥7 Tage (p = 0,014) identifiziert werden. Aufgrund des signifikanten Unterschieds (p < 0,001) zwischen Erlös und kalkulierten Kosten erfolgte eine Analyse nach Faktoren für potenzielle Vergütungsprobleme, welche für eine Aufenthaltsdauer von ≥7 Tagen (p = 0,014) sowie für eine Behandlung auf Intensivstation (p = 0,019) signifikant verblieb.
Schlussfolgerung: Die stationären Versorgungskosten von Patienten mit Frakturen aufgrund epileptischer Anfälle sind hoch und daher gesundheitsökonomisch relevant. Generell scheint die auf Fallpauschalen basierende Vergütung nach G‑DRG die tatsächlichen Kosten zu decken, bei Patienten mit einer langen Liegedauer oder einen Aufenthalt auf Intensivstation können jedoch Vergütungsprobleme bestehen.
Hintergrund: Die stationäre Aufnahme von Patienten mit Prellungen wird in Kliniken der Akutversorgung regelhaft praktiziert. Dabei stehen die pathophysiologischen Unfallfolgen oft im Hintergrund. Ziel dieser retrospektiven monozentrischen Untersuchung war die Untersuchung der Ätiologie sowie der kostenverursachenden Faktoren und Refinanzierung bei Aufnahmen durch Prellungen.
Methodik: Es erfolgte die Abfrage der Patienten entsprechend den Entlassdiagnosen aus dem krankenhausinternen Informationssystem (KIS). Eingeschlossen wurden 117 Patienten in einem Zeitraum von 2 Jahren. Es erfolgten hier die Klassifizierung nach Unfallmechanismus sowie die Einteilung in Altersgruppen. Des Weiteren erfolgte die Kostenkalkulation anhand von abteilungs- und klinikspezifischen Tagessätzen.
Ergebnisse: Bezüglich der Ätiologie war der häusliche Sturz die häufigste Ursache (48,7 %), gefolgt von dem Hochrasanztrauma (22,8 %). Innerhalb der Gruppe des häuslichen Sturzes lag das Durchschnittsalter im Mittel bei 77,8 Jahre. Diese Gruppe zeigte die längste Verweildauer (VWD) mit 5,2 Tagen. Im Rahmen der kalkulierten Kosten zeigte die Gruppe nach häuslichem Sturz die höchsten Kosten mit 2596,24 € bei einem mittleren DRG-Erlös von 1464,51 €.
Diskussion: Die Auswertung der klinikinternen Daten bestätigte die subjektive Wahrnehmung, dass ein Großteil der nach Prellung aufgenommenen Patienten aus der Altersgruppe >65 Jahre stammt. Die Aufnahme erfolgt hier vor dem Hintergrund der in dieser Altersgruppe zunehmenden Komorbiditäten sowie zur Abwendung von Folgeerkrankungen und Folgen der Immobilisierung. Ebenfalls konnte gezeigt werden, dass die Versorgungskosten gesundheitsökomisch relevant sind und die Behandlung in diesen Fällen nicht kostendeckend ist.
