Lefering R, Waydhas C. Prediction of prolonged length of stay on the intensive care unit in severely injured patients-a registry-based multivariable analysis. Front Med (Lausanne) 2024; 11:1358205. [PMID: 38903820 PMCID: PMC11188296 DOI: 10.3389/fmed.2024.1358205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 05/22/2024] [Indexed: 06/22/2024] Open
Abstract
Purpose Mortality is the primary outcome measure in severely injured trauma victims. However, quality indicators for survivors are rare. We aimed to develop and validate an outcome measure based on length of stay on the intensive care unit (ICU). Methods The TraumaRegister DGU of the German Trauma Society (DGU) was used to identify 108,178 surviving patients with serious injuries who required treatment on ICU (2014-2018). In a first step, need for prolonged ICU stay, defined as 8 or more days, was predicted. In a second step, length of stay was estimated in patients with a prolonged stay. Data from the same trauma registry (2019-2022, n = 72,062) were used to validate the models derived with logistic and linear regression analysis. Results The mean age was 50 years, 70% were males, and the average Injury Severity Score was 16.2 points. Average/median length of stay on ICU was 6.3/2 days, where 78% were discharged from ICU within the first 7 days. Prediction of need for a prolonged ICU stay revealed 15 predictors among which injury severity (worst Abbreviated Injury Scale severity level), need for intubation, and pre-trauma condition were the most important ones. The area under the receiver operating characteristic curve was 0.903 (95% confidence interval 0.900-0.905). Length of stay prediction in those with a prolonged ICU stay identified the need for ventilation and the number of injuries as the most important factors. Pearson's correlation of observed and predicted length of stay was 0.613. Validation results were satisfactory for both estimates. Conclusion Length of stay on ICU is a suitable outcome measure in surviving patients after severe trauma if adjusted for severity. The risk of needing prolonged ICU care could be calculated in all patients, and observed vs. predicted rates could be used in quality assessment similar to mortality prediction. Length of stay prediction in those who require a prolonged stay is feasible and allows for further benchmarking.

Abstract
BACKGROUND The interdisciplinary care of severely injured patients is staff and resource intensive. Since the introduction of the G‑DRG system in Germany in 2003, most studies have identified a financial deficit in the care of severely injured patients. The aim of this study was to analyze the effects of the new aG-DRG system introduced in 2020 on cost recovery in the treatment of severely injured patients. For the first time, the costs for organization, certification and documentation as well as the costs for non-seriously injured shock room patients were included. METHODS All patients who were treated in the surgical shock room of the emergency department of the Leipzig University Hospital in 2017 were included. For the analysis, the cost model according to Pape et al. was extended by the module organization, documentation and certification and for the first time the costs for overtriaged patients were considered. A cost calculation was performed for the years 2017-2020 as well a comparison with the respective earnings. RESULTS A total of 834 patients were treated in the shock room and 258 severely injured patients were divided into 3 groups: ISS 9-15 + ICU (n 72; ∅ ISS 11.9; costs per patient 14,715 €),ISS ≥ 16 (n 186; ∅ ISS 27.7; costs per patient 30,718 €) and DRG polytrauma (n 59; ∅ ISS 32.4; costs per patient 26,102 €). CONCLUSION Polytrauma care under the aG-DRG 2020 is in deficit. Overall, in 2020 a deficit of 5858 € per severely injured patient resulted.

Abstract
OBJECTIVES To compare the characteristics of adults admitted to the ICU in Australia and New Zealand after trauma with nonelective, nontrauma admissions. To describe trends in hospital mortality and rates of discharge home among these two groups. DESIGN Retrospective review (2005-2017) of the Australia and New Zealand Intensive Care Society's Center for Outcome and Resource Evaluation Adult Patient Database. SETTING Adult ICUs in Australia and New Zealand. PATIENTS Adult (≥17 yr), nonelective, ICU admissions. INTERVENTION Observational study. MEASUREMENTS AND MAIN RESULTS We compared 77,002 trauma with 741,829 nonelective, nontrauma patients. Trauma patients were younger (49.0 ± 21.6 vs 60.6 ± 18.7 yr; p < 0.0001), predominantly male (73.1% vs 53.9%; p < 0.0001), and more frequently treated in tertiary hospitals (74.7% vs 45.8%; p < 0.0001). The mean age of trauma patients increased over time but was virtually static for nonelective, nontrauma patients (0.72 ± 0.02 yr/yr vs 0.03 ± 0.01 yr/yr; p < 0.0001). Illness severity increased for trauma but fell for nonelective, nontrauma patients (mean Australia and New Zealand risk of death: 0.10% ± 0.02%/yr vs -0.21% ± 0.01%/yr; p < 0.0001). Trauma patients had a lower hospital mortality than nonelective, nontrauma patients (10.0% vs 15.8%; p < 0.0001). Both groups showed an annual decline in the illness severity adjusted odds ratio (odds ratio) of hospital mortality, but this was slower among trauma patients (trauma: odds ratio 0.976/yr [0.968-0.984/yr; p < 0.0001]; nonelective, nontrauma: odds ratio 0.957/yr [0.955-0.959/yr; p < 0.0001]; interaction p < 0.0001). Trauma patients had lower rates of discharge home than nonelective, nontrauma patients (56.7% vs 64.6%; p < 0.0001). There was an annual decline in illness severity adjusted odds ratio of discharge home among trauma patients, whereas nonelective, nontrauma patients displayed an annual increase (trauma: odds ratio 0.986/yr [0.981-0.990/yr; p < 0.0001]; nonelective, nontrauma: odds ratio 1.014/yr [1.012-1.016/yr; p < 0.0001]; interaction: p < 0.0001). CONCLUSIONS The age and illness severity of adult ICU trauma patients in Australia and New Zealand has increased over time. Hospital mortality is lower for trauma than other nonelective ICU patients but has fallen more slowly. Trauma patients have become less likely to be discharged home than other nonelective ICU patients.

Abstract
BACKGROUND The trauma registry of the German Trauma Society (TraumaRegister DGU®) is not only a tool for quality management but also for research purposes. OBJECTIVE Evaluation of the impact of the TraumaRegister DGU® on scientific output and patient treatment. MATERIAL AND METHODS Analysis of publications from the TraumaRegister DGU® with respect to numbers, impact factors, journals, citations and presentations. RESULTS AND CONCLUSION The number and impact factors of publications from the TraumaRegister DGU® rose steeply during the last 10 years and in the last 3 years consisted of 25 publications per year. More than two thirds of them were published in high quality international journals and reflect the great scientific importance. For the German speaking readership and the specific aspects of treatment of the severely injured relevant to Germany, the large number of German language articles are just as important. Independent of the impact factor publications in Deutsches Ärzteblatt, the journal with the highest circulation and Der Unfallchirurg play the most important role. A large amount of scientific information gained from the TraumaRegister DGU® has been included in treatment guidelines and structures. The register is a basic prerequisite for the TraumaNetzwerk DGU®. Since almost all severely injured patients in Germany are now included in the registry, it is possible to obtain epidemiologically reliable data of treatment and outcomes for these patient groups.

Abstract
BACKGROUND Every year up to 35,000 people in Germany are severely injured in accidents in traffic, during work or leisure activities. The 24-h availability of the trauma room as well as surgical and intensive care unit capacities are essential to provide optimal acute care. This study analyzed the frequency of utilization of the resource trauma room in a level I trauma center in the past. METHODS Data of a level I trauma center from 2005 to 2016 including trauma room alerts deployed by the rescue coordination center and the number of patients found to be severely injured (ISS ≥ 16) during trauma room diagnostics were analyzed retrospectively. Additionally, alerts due to trauma mechanism, accompanying by the emergency physician, ventilation and resuscitation were evaluated via a web-based interdisciplinary care capacity system (IVENA) from 2012 to 2016. Therefore, a comparison between the number of trauma room alerts and the number of severely injured patients was performed for the time after 2012. RESULTS For the time from 2012 to 2016, data obtained by IVENA showed a continuous increase in the number of trauma room alerts (n = 367 to n = 623). At the same time, the number of patients admitted under resuscitation (n = 15 to n = 45) as well as ventilated patients (n = 78 to n = 139) increased significantly; however, there was also an increase in the number of trauma alerts due to trauma mechanisms (n = 84 to n = 194) as well as the number of patients admitted to the trauma room not accompanied by an emergency physician (n = 38 to n = 132). The ratio between the number of trauma room alerts and severely injured patients (ISS ≥ 16) increased from 3.1 in 2012 to 5.4 in 2015 and 4.6 in 2016. CONCLUSION The data at hand showed a constant number of severely injured trauma patients admitted to a level I trauma center over the past few years. At the same time, there was a significant increase in utilization of the trauma room; however, in a considerable number of patients admitted to the trauma room the diagnostic process resulted in non-traumatic diagnostic findings. In the analyzed cohort, especially patients admitted to the trauma room due to trauma mechanism or without an accompanying emergency physician contributed to this development, necessitating an increased operational readiness of the trauma room team.

Abstract
Background and purpose Thoracic trauma remains to be a relevant injury to the polytraumatised patient. However, literature regarding how far changes in clinical guidelines for pre- and in-hospital trauma management and diagnostic procedures affect the outcome of multiple injured patients with severe chest injury during a long-term observation period is sparse. Methods Multiple traumatised patients (age≥16y) documented in the TraumaRegister DGU® (TR-DGU) from January 1st 2005 to December 31st 2014 with severe chest trauma (AIS≥3) were included in this study. Demographic data, the pattern of injury, injury severity, radiographic emergency procedures, indication for intubation, duration of mechanical ventilation, emergency surgery, occurrence of complications and mortality were evaluated per year and over time. Results A total of 16,773 patients were analysed. The use of whole body computer tomography increased (p<0.001), while the incidence of plain x-rays decreased (p<0.001). Furthermore, incidence of AISThorax = 3 graded injuries increased (p<0.001) while AISThorax = 4 decreased (p<0.001). Both, rate of patients being intubated at the time of ICU admission decreased (p<0.001) and the time of mechanical ventilation decreased (p<0.001). Additionally, need for emergency surgery, lung failure, sepsis, and multi organ failure all decreased (p<0.001). However, mortality remained unchanged. Interpretation Severity of severe chest trauma and associated complications decreased while diagnostics and treatment improved over time. However, mortality remained unchanged. Our results are in line with those expected in the context of the incidence of CT diagnostics, which has increased parallel to the clinical outcome Thus, our data demonstrate a positive trend in the treatment of patients with severe chest trauma.

Trends in intubation rates and durations in ventilated severely injured trauma patients: an analysis from the TraumaRegister DGU®. Patient Saf Surg 2016; 10:24. [PMID: 27822309 PMCID: PMC5094000 DOI: 10.1186/s13037-016-0109-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2016] [Accepted: 10/13/2016] [Indexed: 01/15/2023] Open
Abstract
Background Endotracheal intubation in severely injured patients is known to be a risk factor for systemic complications. We aimed to examine the changes in intubation rates and durations in severely injured trauma patients, and rates of the systemic complications associated with ventilation changes by using a large trauma registry over the period of 13 years. Methods Patient demographics, Injury Severity Score (ISS), ventilation days, ventilation free days (VFD), and prevalence of systemic complications (sepsis and multiple organ failure (MOF)) were obtained from the TraumaRegister DGU® and were compared over the study period. Results During the study period (2002 – 2014), 35,232 patients were recorded in TraumaRegister DGU®. 72.7 % of patients (n = 25,629) were intubated, and 27.3 % (n = 9603) of patients did not require mechanical ventilation throughout their hospital stay. The mean age was 48 ± 21 years, mean ISS was 27.9 ± 11.5, mean length of ICU stay was 11.7 ± 13.8 days, mean time on mechanical ventilator was 7.1 ± 11.3 days, and mean ventilation free days (spontaneous respiration) was 19.5 ± 11.9 days. We observed a reduction in the intubation rates (87.5 % in 2002 versus 63.6 % in 2014), and early extubation (10 ventilation days in 2002, and 5.9 days in 2014) over time. Conclusion Our study reveals a reduction in intubation rates and ventilation duration during the observation period. Moreover, we were able to observe decreased incidence of systemic complications such as sepsis over the 13 year study period, while no changes in incidence of MOF were registered. The exact relationship can not be proven in our study. This needs to be addressed in further analysis.
