QS231. Physical Examination is a Poor Screening Test for Abdominal-Pelvic Injury in Adult Blunt Trauma Patients

Objective: to assess predictors of intra-abdominal injuries in blunt trauma patients admitted without abdominal pain or abnormalities on the abdomen physical examination. Methods: We conducted a retrospective analysis of trauma registry data, including adult blunt trauma patients admitted from 2008 to 2010 who sustained no abdominal pain or abnormalities on physical examination of the abdomen at admission and were submitted to computed tomography of the abdomen and/or exploratory laparotomy. Patients were assigned into: Group 1 (with intra-abdominal injuries) or Group 2 (without intra-abdominal injuries). Variables were compared between groups to identify those significantly associated with the presence of intra-abdominal injuries, adopting p<0.05 as significant. Subsequently, the variables with p<0.20 on bivariate analysis were selected to create a logistic regression model using the forward stepwise method. Results: A total of 268 cases met the inclusion criteria. Patients in Group I were characterized as having significantly (p<0.05) lower mean AIS score for the head segment (1.0±1.4 vs. 1.8±1.9), as well as higher mean AIS thorax score (1.6±1.7 vs. 0.9±1.5) and ISS (25.7±14.5 vs. 17,1±13,1). The rate of abdominal injuries was significantly higher in run-over pedestrians (37.3%) and in motorcyclists (36.0%) (p<0.001). The resultant logistic regression model provided 73.5% accuracy for identifying abdominal injuries. The variables included were: motorcyclist accident as trauma mechanism (p<0.001 - OR 5.51; 95%CI 2.40-12.64), presence of rib fractures (p<0.003 - OR 3.00; 95%CI 1.47-6.14), run-over pedestrian as trauma mechanism (p=0.008 - OR 2.85; 95%CI 1.13-6.22) and abnormal neurological physical exam at admission (p=0.015 - OR 0.44; 95%CI 0.22-0.85). Conclusion Intra-abdominal injuries were predominantly associated with trauma mechanism and presence of chest injuries.

Cervical spine (CS) injury occurs in 1 to 3 per cent of blunt trauma patients. The goal of this study is to evaluate the use of magnetic resonance imaging (MRI) as an adjunct to CS computed tomography (CT) in the presence of persistent pain with a normal physical examination or obtundation. A retrospective chart review was performed on 389 blunt trauma patients undergoing both CS CT and MRI between 2007 and 2010. Abnormal CT findings were found in 199. The remaining 190 patients with normal CT scans underwent MRI for persistent pain (109), neurologic symptoms (57), or obtundation (24). Motor vehicle crashes predominated (50%) followed by falls (19%) and motorcycle crashes (12%). In the patients with persistent pain, CT showed no acute injury (89%) with subsequent MRI demonstrating ligamentous edema or injury not seen on CT in 12 per cent of patients. No patient required an operation for CS instability. All the obtunded patients demonstrated localizing motion of four extremities. MRI of these patients demonstrated ligamentous edema or injury not seen on CT in 20 per cent of patients. No obtunded patient had CS instability or needed operative intervention. A localizing physical examination in conjunction with normal CS CT safely precludes a CS injury requiring cervical fixation. MRI does not add substantially to this decision-making and the cervical collar can be safely removed.

Abstract Background: Pelvic fractures are common among blunt trauma patients, and timely and accurate diagnosis can improve patient outcomes. However, it remains unclear whether physical examinations are sufficient in this context. This study aims to perform a systematic review and meta-analysis of studies on the diagnostic accuracy and clinical utility of physical examination for pelvic fracture among blunt trauma patients.Methods: Studies were identified using the MEDLINE, EMBASE, and CENTRAL databases starting from the creation of the database to January 2020. A total of 20 studies (49,043 patients with 8,300 cases [16.9%] of pelvic fracture) were included in the quality assessment and meta-analysis. Two investigators extracted the data and evaluated the risk of bias in each study. The meta-analysis involved a hierarchical summary receiver operating curve (ROC) model to calculate the diagnostic accuracy of the physical exam. Subgroup analysis assessed the extent of between-study heterogeneity. Clinical utility was assessed using decision curve analysis.Results: The median prevalence of pelvic fracture was 10.5% (interquartile range: 5.1–16.5). The pooled sensitivity (and corresponding 95% confidence interval) of the hierarchical summary ROC parameters was 0.859 (0.761–0.952) at a given specificity of 0.920, which was the median value among the included studies. Subgroup analysis revealed that the pooled sensitivity among patients with a Glasgow Coma Scale score ≥ 13 was 0.933 (0.847–0.998) at a given specificity of 0.920. The corresponding value for patients with scores ≤ 13 was 0.761 (0.560–0.932). For threshold probability < 0.01 with 10%–15% prevalence, the net benefit of imaging tests was higher than that of physical examination. Conclusion: Imaging tests should be performed in all trauma patients regardless of findings from physical examination or patients’ levels of consciousness. However, the clinical role of physical examination should be considered given the prevalence and threshold probability in each setting.

AbstractBackgroundThe study aims to perform systematic review and meta-analysis to identify the diagnostic accuracy of physical examination for pelvic fracture among the blunt trauma patients.MethodWe will perform a systematic review and meta-analysis for diagnostic test accuracy (DTA). We will include all reports on the diagnostic accuracy of physical examinations for detecting pelvic fractures. We will include the studies designed as prospective or retrospective observational (cohort or cross-sectional) studies or secondary analysis of randomized controlled trials. The target participants are blunt trauma patients with potential pelvic injury. The target condition is pelvic fracture. The index test being investigated is physical examination for pelvic fracture. The reference standard is X-ray or computed tomography to confirm the target condition. We will search MEDLINE, EMBASE and The Cochrane Library inclusive of Cochrane Controlled Trials Register. Two authors will independently screen the study eligibility and extract data. Screening will be a two-step process with initial title/abstract screening followed by full-text screening. We will evaluate the risk of bias independently by two investigators and reported according to the QUADAS-2 tool. In the meta-analysis, we will use a bivariate random-effects model to report the summary receiver operating characteristic (SROC) point (summary values for sensitivity and specificity) and the 95% confidence region around the summary ROC point.Trial registrationThis review is submitted with University hospital medical information network clinical trial registry (UMIN-CTR) [UMIN000038785].

Operative Outcomes

Introduction Traumatic bronchial injury (TBI) is uncommon, difficult to diagnose and often missed. The incidence of TBI among blunt trauma patients is estimated to be around 0.5–2%. Bronchoplastic surgery is indicated in most cases to repair the tracheobronchial airway and preserve lung capacity. There is limited existing literature addressing the management of this condition in view of its rarity. The comprehensive management and outcomes of these patients are discussed. Methods The case notes of all patients who presented with persistent lung collapse due to trauma since July 2017 were reviewed retrospectively. Those patients requiring surgical intervention were included in the review. The mode of injury, clinical, radiological and bronchoscopy findings, concurrent injuries, type of surgery, length of stay (LOS) and operative outcomes were reviewed. Results Out of 11 patients who presented with persistent lung collapse post-blunt trauma, four (36%) were found to have structural bronchial disruption. All of them underwent successful repair of the injured bronchus, without the need of a pneumonectomy. The other seven patients were successfully treated conservatively. Conclusion The repair of the injured bronchus is essential in improving respiratory function and to prevent a pneumonectomy. Routine bronchoscopic evaluation should be performed for all suspected airway injuries as recommended in our management algorithm. Delayed presentations should not hinder urgent referral to thoracic centers for tracheobronchial reconstruction.

Mode Of Transportation

Abstract Introduction: Early police transport (PT) of penetrating trauma patients has the potential to improve survival rates for trauma patients. There are no well-established guidelines for the transport of blunt trauma patients by PT currently. Study Objective: This study examines the association between the survival rate of blunt trauma patients and the transport modality (police versus ground ambulance). Methods: A retrospective, matched cohort study was conducted using the National Trauma Data Bank (NTDB). All blunt trauma patients transported by police to trauma centers were identified and matched (one-to-four) to patients transported by ground Emergency Medical Services (EMS) for analysis. Descriptive analysis was carried out. This was followed by comparing all patients’ characteristics and their survival rates in terms of the mode of transportation. Results: Out of the 2,469 patients with blunt injuries, EMS transported 1,846 patients and police transported 623 patients. Most patients were 16-64 years of age (86.2%) with a male predominance (82.5%). Fall (38.4%) was the most common mechanism of injury with majority of injuries involving the head and neck body part (64.8%). Fractures were the most common nature of injury (62.1%). The overall survival rate of adult blunt trauma patients was similar for both methods of transportation (99.2%; P = 1.000). Conclusion: In this study, adult blunt trauma patients transported by police had similar outcomes to those transported by EMS. As such, PT in trauma should be encouraged and protocolized to improve resource utilization and outcomes further.
