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

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. One-fifth 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]=4.081, 95%CI: 2.364-7.045), head injury (OR=3.920, 95%CI: 2.413-6.368), blood transfusion (OR=2.773, 95%CI: 1.668-4.609), SI (OR=2.132, 95%CI: 1.364-3.332), ISS (OR=1.077, 95%CI: 1.057-1.096), and age (OR=1.040, 95%CI: 1.026-1.054). CONCLUSIONS: Patients with shorter EDLOS had different baseline characteristics and hospital outcomes compared with patients with longer EDLOS. Patients with prolonged EDLOS had better outcomes; however, the burden of prolonged boarding in the ED needs further elaboration.

Trouble in Tiger country: isolated traumatic pancreatic transection - a case report.

Isolated pancreatic transection is a rare surgical condition that occurs more commonly following blunt abdominal trauma. It carries a high degree of morbidity and mortality, and the management remains a source of debate as universally accepted guidelines are not well established owing to the paucity in clinical experience and large series. We presented a case of an isolated pancreatic transection following blunt abdominal trauma. The surgical management of pancreatic transection has evolved over the decades from aggressive approaches to more conservative measures. Given the lack of large series and clinical experience, no universal consensus exists, except for applying damage control surgery and resuscitation principles in critically unstable patients. For transections of the main pancreatic duct, most recommend excision of the distal pancreas. Concerns over the iatrogenic complications of wide excisions, particularly diabetes mellitus, have led to reconsideration and more conservative approaches, but it may fail in some cases.

Predisposing Factors and Outcome of Acute Kidney Injury After Blunt Trauma: A 10-Year Study.

INTRODUCTION: Acute kidney injury (AKI) indicates an impairment of the renal function following blunt trauma. It is multifactorial and associated with an increased risk of morbidity and mortality. The incidence and risk factors of AKI in young patients with trauma are not well-described. This study aimed to evaluate the incidence, clinical characteristics, and outcomes of post-traumatic AKI. We hypothesized that AKI is associated with worse outcomes in patients with trauma. METHODS: This was a retrospective study of all adult trauma patients admitted to a level 1 trauma center between 2011 and 2021. AKI was diagnosed on the basis of the Kidney Disease Improving Global Outcomes criteria. Data were collected and analyzed for patients with and without AKI using chi-square test and Student's t-test. Multivariate logistic regression analysis and Kaplan-Meier curves were performed. RESULTS: A total of 17,341 patients with trauma were evaluated, of which 140 (0.8%) developed AKI. Patients with AKI were older (40 ± 20 versus 32 ± 16 y), had more comorbidities, and had a higher injury severity score (ISS) and in-hospital mortality (65% versus 3.2%) than non-AKI patients. Direct trauma to the kidney was reported in only nine (6.4%) patients in the AKI group. Among patients with AKI, nonsurvivors had a higher ISS and were more likely to have hypotension, elevated serum lactate, positive troponin, and a lower platelet-to-lymphocyte ratio than survivors. Multiple logistic regression analyses showed that age, ISS, acute respiratory distress syndrome, blood transfusion, diabetes mellitus, onadmission Glasgow coma scale score, and shock index were predictors of AKI in trauma patients, whereas ISS (odds ratio (OR) = 1.05; 95% confidence interval (CI):1.003-1.100; P = 0.03), serum lactate level (OR = 1.25; 95% CI: 1.019-1.533; P = 0.03), and hypotension (OR = 3.22; 95% CI: 1.044-9.945; P = 0.04) were independent predictors of mortality in patients with posttraumatic AKI. Kaplan-Meier survival analysis showed significant differences in mortality among the three stages of AKI (P = 0.03), with the worst outcome in stage III. However, after adjusting for age, hypotension, and ISS, the Cox regression model showed that only stage I had better survival than stages II and III, whereas no survival difference was noted between stages II and III (P = 0.06). CONCLUSIONS: AKI in young trauma patients is uncommon and associated with a prolonged hospital course and higher mortality. This study identified factors that independently predicted the development of AKI and its outcomes in patients with trauma. However, further prospective and multicenter studies are required to minimize the incidence and complications of posttraumatic AKI.

Rotterdam and Marshall Scores for Prediction of in-hospital Mortality in Patients with Traumatic Brain Injury: An observational study.

Background: We aimed to assess the prognostic value of Rotterdam and Marshall scoring systems to predict in-hospital mortality in patients with traumatic brain injury (TBI).Methods: A retrospective analysis was conducted for patients with TBI who underwent head computerized tomography (CT) scan at a Level I trauma center between 2011 and 2018. Receiver operating characteristic (ROC) curves were used to determine the cutoff values for predicting in-hospital mortality.Results: A total of 1035 patients with TBI were included with a mean age of 30 years. The mean Rotterdam and Marshall scores were higher among non-survivors (p = .001). Patients with higher Rotterdam (>3) or Marshall (>2) CT scores were older, had higher injury severity scores and in-hospital mortality and had lower GCS and blood ethanol levels than those with lower scores. The cutoff point of Rotterdam score was 3.5 (sensitivity, 61.2%; specificity, 85.6%) and Marshall score was 2.5 (74.3% sensitivity and 76.3% specificity). Multivariable logistic regression analyses showed that Marshall and Rotterdam scoring systems were independent predictors of mortality (odds ratio 8.4; 95% confidence interval 4.95-14.17 and odds ratio 4.4; 95% confidence interval 2.36-9.39, respectively).Conclusion: Rotterdam and Marshall CT scores have independent prognostic values in patients with TBI even in alcoholic patients.

Traumatic Pancreatic Injury Presentation, Management, and Outcome: An Observational Retrospective Study From a Level 1 Trauma Center.

BACKGROUND: We aimed to study the presentation, management, and outcomes of patients with a pancreatic traumatic injury. METHODS: We retrospectively analyzed data for all patients who were admitted with pancreatic injuries between 2011 and 2017 at the only level 1 trauma center in the country. RESULTS: There were 71 patients admitted with pancreatic trauma (0.6% of trauma admissions and 3.4% of abdominal injury admissions) with a mean age of 31 years. Sixty-two patients had pancreatic injury grade I-II and nine had injury grade III-IV. Thirty-eight percent had Glasgow Coma Scale (GCS) <9 and 73% had injury Severity Score (ISS) >16. The level of pancreatic enzymes was significantly proportional to the grade of injury. Over half of patients required laparotomy, of them 12 patients had an intervention on the pancreas. Eight patients developed complications related to pancreatic injuries ranging from pancreatitis to pancreatico-cutaneous fistula while 35% developed hemorrhagic shock. Mortality was 31% and regardless of the grade of injury, the mortality was associated with high ISS, low GCS, and presence of hemorrhagic shock. CONCLUSION: Pancreatic injuries following blunt trauma are rare, and the injured subjects are usually young men. However, most injuries are of low-grade severity. This study shows that regardless of the pancreatic injury grade on-admission shock, higher ISS and lower GCS are associated with worse in-hospital outcomes. Non-operative management (NOM) may suffice in patients with lower grade injuries, which may not be the case in patients with higher grade injuries unless carefully selected.

Combination of Common Problem in a Rare Disease: Right Iliac Fossa Pain in a Chronic Myeloid Leukemia Patient.

Abdominal symptoms in patients with hematological malignancies can occur due to an array of pathologies. Two diagnoses with similar presentation albeit, generally opposite treatment modalities, are typhlitis (inflammation of cecum) and acute appendicitis. Both diagnoses have to be kept in mind in such a patient presenting with right lower quadrant (RLQ) pain. Sagacious clinical judgment along with the aid of radiological imaging may help in differentiating between the two conditions. We present a case of a young male with chronic myeloid leukemia (CML) on imatinib, diagnosed and started on therapy four years earlier, who presented with symptoms of RLQ pain not typical of acute appendicitis. The accurate diagnosis was made with the assistance of ultrasound (US) imaging and prompt surgical therapy was instituted followed by a smooth postoperative recovery.

Small Intestinal Diverticulosis: A Rare Cause of Intestinal Perforation Revisited.

Jejunoileal diverticulosis (JID) is a rare and nonspecific symptomatic disease. It is usually an acquired condition associated with false diverticula and integrated with colonic diverticulosis which can be diagnosed incidentally or later with complications. A sixty-nine-year-old male presented with sudden onset generalized abdominal pain. Computed tomography (CT) imaging was suggestive of ileal diverticulitis with localized perforation. The patient was treated conservatively with IV fluids and antibiotics and kept nil per orem for three days and discharged after symptoms subsided. The patient returned with a similar presentation but with a greater intensity. CT with oral contrast revealed evidence of distal ileal perforation. The terminal ileum was resected, and a double barrel ileostomy was created. Six months later, the stoma was reversed after resecting 50 cm of proximal terminal ileum which included all diverticula. The patient had a smooth postoperative recovery. Small bowel diverticulitis is generally managed conservatively unless the patient's clinical condition mandates urgent exploration. This report may add knowledge and lead to a change in clinical practice.

Bio-Shock Index: Proposal and Rationale for a New Predictive Tool for In-Hospital Mortality in Patients with Traumatic Brain Injury.

BACKGROUND: We proposed a novel prognostic tool for the prediction of in-hospital mortality based on a combination of hemodynamic parameters and biomarkers in patients with traumatic brain injury (TBI). We hypothesized that a combination of shock index (SI) with high sensitive troponin T (HsTnT), the Bio-Shock Index (Bio-SI), has better prognostic power than its individual components. METHODS: A retrospective chart review was conducted (2011-2018) for patients with TBI. Patients were categorized into 2 groups (low and high Bio-SI) based on the receiver operating characteristic curve. RESULTS: A total of 2619 patients were admitted with TBI, and 1471 fulfilled the inclusion criteria and 73% had high Bio-SI (≥10). High Bio-SI values were associated with more intraventricular hemorrhage (P = 0.001), brain edema (P = 0.001), and had lower mean arterial pressure (P = 0.001), admission Glasgow Coma Scale score (P = 0.001), and higher SI (P = 0.001), serum lactate (P = 0.001), HsTnT values (P = 0.001), and Rotterdam score (P = 0.03). Patients with high Bio-SI had a prolonged hospital (P = 0.003) and intensive care unit stay (P = 0.001); longer ventilatory days (P = 0.001) and had higher rates of pneumonia (P = 0.001), sepsis (P = 0.001), and in-hospital mortality (P = 0.001). The Bio-SI showed high sensitivity and negative predictive value (91.4% and 94.4%, respectively) as compared with elevated SI (50.2% and 87.6%, respectively) and positive troponin (79.7% and 93.7%, respectively). CONCLUSIONS: The Bio-SI is potentially a better tool than its individual components to predict in-hospital mortality among patients with TBI; however, HsTnT alone outperforms SI. Prospective studies and multicenter trials studying troponin levels and SI in all patients with TBI with the inclusion of outcome scores will prove or disprove the predictability of the new index.
