Time spent in the emergency department and mortality rates in severely injured patients admitted to the intensive care unit: An observational study (original) (raw)

The impact of emergency department length of stay on the outcomes of trauma patients requiring hospitalization: a retrospective observational study

World Journal of Emergency Medicine

BACKGROUND: We aimed to explore the impact of the emergency department length of stay (EDLOS) on the outcome of trauma patients. METHODS: A retrospective study was conducted on all trauma patients requiring hospitalization between 2015 and 2019. Patients were categorized into 4 groups based on the EDLOS (<4 h, 4-12 h,12-24 h, and >24 h). Data were analyzed using Chi-square test (categorical variables), Student's t-test (continuous variables), correlation coefficient, analysis of variance and multivariate logistic regression analysis for identifying predictors of short EDLOS and hospital mortality. RESULTS: The study involved 7,026 patients with a mean age of 32.1±15.6 years. Onefifth of patients had a short EDLOS (<4 h) and had higher level trauma team T1 activation (TTA-1), higher Injury Severity Score (ISS), higher shock index (SI), and more head injuries than the other groups (P=0.001). Patients with an EDLOS >24 h were older (P=0.001) and had more comorbidities (P=0.001) and fewer deaths (P=0.001). Multivariate regression analysis showed that the predictors of short EDLOS were female gender, GCS, SI, hemoglobin level, ISS, and blood transfusion. The predictors of mortality were TTA-1 (odds ratio [OR]=4.

Factors influencing lengths of stay in the intensive care unit for surviving trauma patients: a retrospective analysis of 30,157 cases

Critical care (London, England), 2014

There are many potential influencing factors that affect the duration of intensive care treatment for patients who have survived multiple trauma. Yet the respective factors' relevance to ICU length of stay (LOS) has been rarely studied. Thus, the aim of the present study was to investigate to what extent specific factors influence ICU LOS in surviving trauma patients. We retrospectively analyzed a dataset of 30,157 surviving trauma patients from the TraumaRegister DGU® who were older than six years of age and received subsequent intensive care treatment for more than one day, from 2002 to 2011. Univariate analysis and multiple linear regression analysis were used to examine 25 categorical pre- and post-trauma parameters. Univariate analysis confirmed the impact of all analyzed factors. In subsequent multiple linear regression analyses, coefficients ranged from -1.3 to +8.2 days. The factors that influenced the prolongation of ICU LOS most were renal failure (+8.1 days), sepsis (...

The Association between Time Intervals in Emergency Medical Services and In-hospital Mortality of Trauma Patients

Original Article intROductiOn Trauma, with over 6 million deaths annually, is the leading cause of mortality in the world and imposes huge socioeconomic burdens. [1,2] This issue is more critical in the low-and middle-income countries, where resources and capacities for timely management of trauma patients are limited. In Iran, trauma causes over 27,000 deaths plus 800,000 disabilities, and over 60% of deaths occur at the scene or on the way to the hospital. [3] The "Golden hour of trauma" is a well-known premise in literature, which underlines the importance of patient transport and delivering definite trauma care at a trauma center within an hour of injury. [4] Meeting such standard of care requires emergency medical service (EMS) to utilize all its resources including ambulances, choppers, and personnel at the highest possible level for traumatic injuries. Hence, this puts the whole EMS system under pressure and may increase the risk of injuries, burnout, and depreciation. [5-8] Context: While the clinical practice recommends field stabilization in trauma patients, in some situations, the speed of transport is crucial. Aims: This study aimed to evaluate the association between emergency medical services (EMS) time intervals (response time [RT], scene time [ST], and transport time [TT]) and in-hospital mortality in trauma patients in Tehran, the largest metropolis of Iran. Settings and Design: A prospective cohort study was conducted between May 2017 and April 2018. Methods: All EMS operations related to trauma events in the Tehran city that were transferred to three targeted major trauma centers were included. Statistical Analysis: Logistic regression analysis was used to assess the relationship between EMS time intervals and other risk factors of trauma death. Results: A total of 14,372 trauma patients were included in the final analysis. In-hospital mortality occurred in 225 (1.6%) patients. After adjustment for confounding variables, older age (odds ratio [OR] = 1.04/year), female gender (OR = 2.16), low Mechanism, Glasgow Coma Scale (GCS), age, and arterial pressure score (OR = 0.84 for each unit), low GCS (OR = 0.56 for each unit), longer ST (OR = 1.17/10 min), and longer TT (OR = 1.21/10 min) were found to be risk factors for death in trauma. Conclusions: Our study showed that in-hospital mortality of trauma patients correlated with longer EMS ST and TT, but the RT was not associated with mortality. Our results recommend that the EMS system should consider ST and TT rather than RT, as indexes of quality control in prehospital care of trauma patients.

Srpski arhiv za celokupno lekarstvo

Introduction/Objective. The aim of this study was to determine independent predictors and the best trauma scoring system (REMS, RTS, GSC, SOFA, APPACHE II) of in-hospital mortality in patients with severe trauma at the Department of Emergency, Emergency Center, Clinical Center of Serbia, Belgrade. Methods. Longitudinal study included 208 consecutive patients with severe trauma. In order to determine independent survival contributors, univariate and multivariate Cox regression analyses were performed. The power of above-mentioned scoring systems (measured at admission to the Emergency center) to predict mortality was compared using the area under the curve (AUC). Results. There were 208 patients (159 male, 49 female), with the average age of 47.3 ? 20.7 years. Majority of patients were initially intubated (86.1%) on admission to the emergency department, and 59.6% patients were sedated before intubation. After finishing of diagnostic procedures, 17 patients were additionally intubate...

A Comparison of Prehospital and Hospital Data in Trauma Patients

The Journal of Trauma: Injury, Infection, and Critical Care, 2004

The use of prehospital data as an indicator for trauma team activation has been established. The relationship between field (Fd) and emergency department (ED) systolic blood pressure (SBP), Glasgow Coma Scale (GCS) score, and airway control as it relates to outcomes is unclear. We hypothesized that ED and Fd physiologic parameters are equally valid predictors of outcomes. In addition, we hypothesized that early field intubation will improve survival compared with later ED intubation. Methods: Trauma registry data from two academic Level I centers from 1994 to 2001, excluding all transfers and burn patients, were analyzed using Wilcoxon signed-rank test and multivariate logistic regression with appropriate adjustments. Results: There were 19,409 patients, 16,277 blunt and 3,132 penetrating trauma. There were 3,571 Fd and 746 ED intubations. ED intubation was associated with increased risk of fatal outcome compared with nonintubated patient (adjusted odds ratio, 3.1; p < 0.0001) and field intubations (adjusted odds ratio, 3.0; p < 0.0001). ED-GCS score was not significantly different from Fd-GCS score, with 82% having the same GCS category. This was not the case for SBP, and only in 60% of the cases were ED-SBP and Fd-SBP in the same category. In 31% of the patients, the ED-SBP increased, and in 9% of cases, the ED-SBP decreased compared with Fd-SBP. This was true for both blunt and penetrating trauma. Both Fd-SBP and ED-SBP were independent predicators of fatal outcome, and mortality rate significantly increased if ED-SBP category decreased compared with Fd-SBP. Conclusion: Early field intubation was associated with a decreased risk of fatal outcome compared with ED intubation. ED-GCS score was not significantly different from Fd-GCS score, and either one can be used to predict fatal outcome. However, ED-SBP was different from Fd-SBP in 40% of the patients, with the majority of cases having higher ED-SBP. Although ED-SBP was a better predictor of outcome, the best model is achieved when both ED and field SBP are used.

The intensive care unit admission predicting the factors of late complications in trauma patients: A prospective cohort study

Archives of Trauma Research, 2019

Original Article Background: Organ failure (OF) and sepsis are important causes of late death in trauma. Previous studies reported the methods that could predict OF at the time of patient arrival. However, most of the evidence is from high-income countries, where health-care systems were different from developing countries. This research aimed to identify the factors to predict late complications in trauma patients in surgical intensive care units (SICUs). Methods: This study was a secondary data analysis from the THAI-SICU study, which was a prospective cohort study in nine university-based-SICUs in Thailand. Late complications were defined as any OF or sepsis that occurred after 48 h of ICU admission. Multivariable logistic regression was conducted to identify the significant factors. Results: Three hundred and fourteen patients were eligible for the analysis. Late complications occurred in 60 patients (19%). Patients who had complications had higher Acute Physiology and Chronic Health Enquiry (APACHE II) (15.8 vs. 12.4, P = 0.02) and Sequential OF Assessment (SOFA) scores on admission (6.7 vs. 3.8, P < 0.001). Multivariable analysis showed that current smoking (odds ratio [OR] =1.9, 95% confidence interval [CI]; 1.03-3.67, P = 0.04) and SOFA score on admission (OR = 1.2, 95% CI; 1.12-1.29, P < 0.001) increased the risk of late complications. Late complications had hazards ratio of mortality of 5.9 (95% CI; 2.53-13.88, P < 0.001). Conclusions: The incidence of late complications in trauma patients in the SICU was 19%. Current smoking and SOFA score might be valuable in future prediction of late complications during admission.

Predicting factors associated with in-hospital mortality in severe multiple-trauma patients

Archives of Trauma Research

Original Article intROductiOn Trauma is the leading cause of death under the age of 40 years [1] and one of the most important causes of death and disability at all ages. [1,2] According to the world health organization report entitled Road Traffic Injuries, released in February 2020, approximately 1.35 million people die each year due to road accidents alone. According to these reports, 93% of road deaths occur in low-to middle-income countries (Iran is in the middle-income group); however, only 60% of the world's vehicles are in these countries. [2] In addition, trauma is one of the four leading causes of death in middle-income countries such as Iran. [3] Trauma has different causes; road accidents, followed by falls from heights, are the most common causes of trauma. [3-8] Previous studies have shown that these two mechanisms alone account for about 80% of trauma cases. [1,3,5,6] This number Background and Objectives: Traumatic injuries have become a health problem worldwide, especially in low-to middle-income countries. Therefore, this study was conducted to identify predicting factors of death in adult severe multiple trauma patients. Methods: This retrospective cross-sectional study was performed on 1397 adult multiple trauma patients referred to the emergency department (ED) of Poursina Hospital between June 2019 and August 2021. The demographic characteristics, on admission clinical parameters, laboratory tests, the need for packed red blood cell transfusion, and the need for endotracheal intubation were recorded. The revised trauma score (RTS) was calculated according to the physiological variables collected on admission to ED. The primary outcome was 1-day mortality after admission. Results: The mean age of subjects was 37.12 ± 13.61 (18-60) years, and 1250 (89.5%) subjects were male. The 1-day mortality was 339 patients (24.3%). Initial RTS score and the mean Glasgow coma scale (GCS) scores were significantly higher in the survived group than in the nonsurvived group (6.6 ± 1.2 vs. 4.9 ± 1.0, 10.2 ± 3.7 vs. 4.9 ± 2.4, P < 0.001). The multivariate analysis resulted in low GCS (odds ratio [OR] = 1.527, 95%CI 1.434-1625, P < 0.001), low O 2 saturation (OR = 1.023, 95%CI 1.003-1.043, P = 0.022), and need for intubation in the ED (OR = 0.696, 95%CI 0.488-0.993, P = 0.046) as predictors of 1-day mortality. The area under the curves receiver operating characteristics of RTS and GCS scores to predict mortality were 0.853 (95% CI: 0.831-0.874) and 0.866 (95% CI: 0.846-0.887), respectively. Conclusion: Multiple factors associated with 1-day mortality were reduced GCS score, decreased oxygen saturation, and need for intubation in the ED. The RTS and GCS scores are good predictors of mortality survival in multiple trauma patients.

Risk factors for death of trauma patients admitted to an Intensive Care Unit

Revista Latino-Americana de Enfermagem, 2020

Objective: To analyze the risk factors for death of trauma patients admitted to the intensive care unit (ICU). Method: Retrospective cohort study with data from medical records of adults hospitalized for trauma in a general intensive care unit. We included patients 18 years of age and older and admitted for injuries. The variables were grouped into levels in a hierarchical manner. The distal level included sociodemographic variables, hospitalization, cause of trauma and comorbidities; the intermediate, the characteristics of trauma and prehospital care; the proximal, the variables of prognostic indices, intensive admission, procedures and complications. Multiple logistic regression analysis was performed. Results: The risk factors associated with death at the distal level were age 60 years or older and comorbidities; at intermediate level, severity of trauma and proximal level, severe circulatory complications, vasoactive drug use, mechanical ventilation, renal dysfunction, failure ...

Survival outcomes after prolonged intensive care unit length of stay among trauma patients: The evidence for never giving up

Surgery, 2016

Background. Prolonged intensive care unit length of stay (ICU-LOS) is associated with high mortality for medical and surgical patients. Existing literature suggests that this may not be true for trauma patients. The objective of this study was to determine mortality associated with varying ICU-LOS among trauma patients and to assess for independent predictors of mortality. Methods. Adult ICU patients (16-64 years) in the National Trauma Data Bank (2007-2012) were categorized by ICU-LOS: 1, 2-9, 10-40, and >40 days (determined based on inflection points). Multivariable logistic regression was used to determine associations with mortality for each. Models accounted for clustering of patients within hospitals and potential confounding associated with: age, gender, race/ethnicity, insurance status, Injury Severity Score, blunt/penetrating injury, Glasgow Coma Scale, in-hospital complications, ventilator dependency, and emergency department disposition. Results. Among the 596,598 patients included, 6.5% (n = 38,812) died. Mortality varied with ICU-LOS: 9.9%, 4.9%, 6.6%, and 9.8%. Age >35 years was a significant predictor of mortality in each. Injury Severity Score and the Glasgow Coma Scale independently predicted mortality in patients with LOS #40 days as did penetrating injuries, cardiac arrest, and renal failure. Identification with non-Hispanic black race/ethnicity was also consistently significant. Once patients survived 9 days, mortality steadily decreased, remaining relatively stable until 40 days. Thereafter, trauma patients continued to demonstrate high survival with >87% remaining alive in the ICU >90 days. Conclusion. The results reveal that in contrast to expectations of high mortality associated with prolonged ICU-LOS, critically injured adult trauma patients who do not die within the first few days demonstrate an enhanced ability to survive, with an overall survival of >92% and maintained at >85% among extreme ICU-LOS (>40 days). The data advocate the utility of aggressive critical-care support for trauma patients, irrespective of duration of ICU stay.
