An Analysis of Injured Patients Treated at Level 1 Trauma Centers Versus Other Centers: A Scoping Review.

INTRODUCTION: Trauma systems continue to evolve to create the best outcomes possible for patients who have undergone traumatic injury. OBJECTIVE: This review aims to evaluate the existing research on outcomes based on field triage to a Level 1 trauma center (L1TC) compared to other levels of hospitals and nontrauma centers. METHODS: A structured literature search was conducted using PubMed, CINAHL, Embase, and the Cochrane Database. Studies analyzing measures of morbidity, mortality, and cost after receiving care at L1TCs compared to lower-level trauma centers and nontrauma centers in the United States and Canada were included. Three independent reviewers reviewed abstracts, and two independent reviewers conducted full-text review and quality assessment of the included articles. RESULTS: Twelve thousand five hundred fourteen unique articles were identified using the literature search. 61 relevant studies were included in this scoping review. 95.2% of included studies were national or regional studies, and 96.8% were registry-based studies. 72.6% of included studies adjusted their results to account for injury severity. The findings from receiving trauma care at L1TCs vary depending on severity of injury, type of injury sustained, and patient characteristics. Existing literature suffers from limitations inherent to large de-identified databases, making record linkage between hospitals impossible. CONCLUSIONS: This scoping review shows that the survival benefit of L1TC care is largest for patients with the most severe injuries. This scoping review demonstrates that further research using high-quality data is needed to elucidate more about how to structure trauma systems to improve outcomes for patients with different severities of injuries and in different types of facilities.

Individualized Performance Feedback to Surgical Residents Improves Appropriate Venous Thromboembolism Prophylaxis Prescription and Reduces Potentially Preventable VTE: A Prospective Cohort Study.

OBJECTIVE: To investigate the effect of providing personal clinical effectiveness performance feedback to general surgery residents regarding prescription of appropriate venous thromboembolism (VTE) prophylaxis. BACKGROUND: Residents are frequently charged with prescribing medications for patients, including VTE prophylaxis, but rarely receive individual performance feedback regarding these practice habits. METHODS: This prospective cohort study at the Johns Hopkins Hospital compared outcomes across 3 study periods: (1) baseline, (2) scorecard alone, and (3) scorecard plus coaching. All general surgery residents (n = 49) and surgical patients (n = 2420) for whom residents wrote admission orders during the first 9 months of the 2013-2014 academic year were included. Outcomes included the proportions of patients prescribed appropriate VTE prophylaxis, patients with preventable VTE, and residents prescribing appropriate VTE prophylaxis for every patient, and results from the Accreditation Council for Graduate Medical Education resident survey. RESULTS: At baseline, 89.4% of patients were prescribed appropriate VTE prophylaxis and only 45% of residents prescribed appropriate prophylaxis for every patient. During the scorecard period, appropriate VTE prophylaxis prescription significantly increased to 95.4% (P < 0.001). For the scorecard plus coaching period, significantly more residents prescribed appropriate prophylaxis for every patient (78% vs 45%, P = 0.0017). Preventable VTE was eliminated in both intervention periods (0% vs 0.35%, P = 0.046). After providing feedback, significantly more residents reported receiving data about practice habits on the Accreditation Council for Graduate Medical Education resident survey (87% vs 38%, P < 0.001). CONCLUSIONS: Providing personal clinical effectiveness feedback including data and peer-to-peer coaching improves resident performance, and results in a significant reduction in harm for patients.

Synchronous tracheostomy and gastrostomy placement results in shorter length of stay in traumatic brain injury patients.

BACKGROUND: American Society for Parenteral and Enteral Nutrition (ASPEN) guidelines recommend gastrostomy for patients suspected to require enteral access device for 4-6 weeks. Our hypothesis was that traumatic brain injury (TBI) patients undergoing synchronous tracheostomy/gastrostomy (SYNC) compared to tracheostomy first (DELAY) have shorter length of stay (LOS) but higher rates of unnecessary gastrostomy. METHODS: Retrospective review of TBI patients requiring tracheostomy in 2017-2022 â€‹at a Level 1 trauma center was conducted. SYNC and DELAY patients were compared, and CoxPH analysis was performed for LOS. RESULTS: 394 patients were included [mean age: 42 (SD:18); mortality: 9 â€‹%]. The DELAY group had longer LOS (39 vs 32 days, p â€‹< â€‹0.001). There was no significant difference in unnecessary gastrostomy rate between groups (p â€‹= â€‹0.1331). In adjusted hazard analysis, SYNC predicted shorter LOS (HR:1.54; 95 â€‹% CI:1.20-1.98, p â€‹< â€‹0.001). CONCLUSIONS: Synchronous gastrostomy was associated with shorter length of stay and similar rates of unnecessary gastrostomy in TBI patients.

Performance Improvement Program Review of Institutional Massive Transfusion Protocol Adherence: An Opportunity for Improvement.

BACKGROUND: Given the acuity of patients who receive MTPs and the resources they require, MTPs are a compelling target for performance improvement. This study evaluated adherence with our MTP's plasma:red blood cell ratio (FFPR) of 1:2 and platelet:red blood cell ratio (PLTR) of 1:12, to test the hypothesis that ratio adherence is associated with lower inpatient mortality. MATERIALS AND METHODS: The registry of an urban level I trauma center was queried for adult patients who received at least 6 units of packed red blood cells within 4 hours of presentation. Patients were excluded for interfacility transfer, cardiac arrest during the prehospital phase or within one hour of arrival, or for head AIS ≥5. Univariate analysis and multiple logistic regressions were performed to identify variables associated with early transfusion protocol noncompliance and the effect on inpatient mortality. RESULTS: Three hundred and eighty-three patients were included, with mean ISS of 25.9 ± 13.3 and inpatient mortality of 28.5%. Increasing age, ISS, INR, and total units of blood product transfused were associated with increased odds of mortality, while an increase in revised trauma score was associated with a decreased odds ratio of mortality. Achieving our goal ratios were protective against mortality, with OR of .451 (P = .013) and .402 (P=.003), respectively. DISCUSSION: Large proportions of critically injured patients were transfused fewer units of plasma and platelets than our MTP dictated; failure to achieve intended ratios at 4 hours was strongly associated with inpatient mortality. MTP processes and outcomes should be critically assessed on a regular basis as part of a mature performance improvement program to ensure protocol adherence and optimal patient outcome.

Trust but Verify? Utility of Intraoperative Angiography After Revascularization for Vascular Trauma.

BACKGROUND: Trauma surgical dogma teaches that patients should have intraoperative angiography (IA) if the surgeon cannot identify a pulse in the injured extremity following a vascular repair. This study was undertaken to assess the utility of IA in trauma patients who underwent open brachial or femoral artery revascularization. METHODS: Retrospective analysis of the Prospective Observational Vascular Injury Trial (PROOVIT) database from 2013 to 2021 evaluated patients >15 years with penetrating or blunt injuries requiring operative intervention of the brachial, superficial femoral, or common femoral arteries. Prospective Observational Vascular Injury Trial data evaluated included documented pulse in the injured extremity at revascularization completion, adjunctive IA, immediate revision, and vascular reintervention during the hospitalization. RESULTS: Of the 5057 patients with vascular injury, 185 patients met our inclusion criteria. The majority were male (86.5%) with a median age, injury severity score, and systolic blood pressure of 29, 12, and 117, respectively. Of the study patients, 39% underwent IA, 14% had immediate revision, and 8% required vascular reoperation during their admission. Patients who underwent IA and with no documented palpable pulse after repair were significantly more likely to require immediate revision before leaving the operating room (22% vs 9%, P = .013) and were not more likely to require reoperation, than those who did not undergo IA (7% vs 9%, P = .613). CONCLUSIONS: Intraoperative angiography is a valuable tool for surgeons for vascular extremity trauma and is associated with a greater rate of immediate revision. Familiarity with angiographic technique is essential for vascular trauma and should be a focal point of training.

Key Findings on Computed Tomography of the Head that Predict Death or the Need for Neurosurgical Intervention From Traumatic Brain Injury.

BACKGROUND: Traumatic brain injury (TBI) requires rapid management to avoid secondary injury or death. This study evaluated if a simple schema for quickly interpreting CT head (CTH) imaging by trauma surgeons and trainees could be validated to predict need for neurosurgical intervention (NSI) or death from TBI within 24 hours. METHODS: We retrospectively reviewed TBI patients presenting to our trauma center in 2020 with blunt mechanism and GCS ≤ 12. Primary independent variables were presence of 7 normal findings on CTH (CSF at foramen magnum, open fourth ventricle, CSF around quadrigeminal plate, CSF around cerebral peduncles, absence of midline shift, visible sulci/gyri, and gray-white differentiation). Trauma surgeons and trainees separately evaluated each patient's CTH, scoring findings as normal or abnormal. Primary outcome was NSI/death in 24 hours. RESULTS: Our population consisted of 444 patients; 21.4% received NSI or died within 24 hours. By trainees' interpretation, 5.8% of patients without abnormal findings had NSI/death vs 52.0% of patients with ≥1 abnormality; attending interpretation was 8.7% and 54.9%, respectively (P < .001). Sulci/gyri effacement, midline shift, and cerebral peduncle effacement maximized sensitivity and specificity for predicting NSI/death. Considering pooled results, when ≥1 of those 3 findings was abnormal, sensitivity was 77.89%, specificity was 80.80%, positive predictive value was 52.48%, and negative predictive value was 93.07%. DISCUSSION: Any single abnormality in this schema significantly predicted a large increase in NSI/death in 24 hours in TBI patients, and three particular findings were most predictive. This schema may help predict need for intervention and expedite management of moderate/severe TBI.

Clinical decompensation after trauma laparotomy: It's probably not a pulmonary embolus.

Introduction Computed Tomography (CT) to rule out pulmonary embolus (PE) is often ordered during post-trauma laparotomy clinical decompensation (CD) involving fever, tachycardia, tachypnea, and/or leukocytosis. We hypothesize this diagnostic modality is low-yield in the postoperative period when surgery-related sequelae are more probable. Methods This is a single-center retrospective cohort study of patients who underwent trauma laparotomy and had subsequent CT for CD from March 19, 2019 to June 30, 2022. Descriptive statistics and multiple logistic regression were performed. The primary outcome was saddle and lobar PE incidence. Results 1032 adult patients underwent trauma laparotomy with 434 undergoing CT for CD: 137 CT abdomen and pelvis only, 30 CTPE, 265 both. The majority (80.2 %) was male, age 33[interquartile range (IQR) 24-45], suffered penetrating mechanism (57 %), and had ISS 23[IQR16-30]. Injuries at laparotomy included 47 % solid organ, 62 % GI tract, 7 % biliary, 11 % vascular, and 42 % other. 176 (41 %) required damage control laparotomy. Median time to CT post-laparotomy was 174 h [111-235] with saddle and lobar PE in 3 (1 %), peripheral PE 18 (5 %), and abdominal abscess, leak, fluid, or pseudoaneurysm in 222 (51 %). Clinical management was altered (40 %) by antibiotics, therapeutic anticoagulation, drainage, aspiration, filter, thrombectomy, or surgical operation. Patients for whom CT findings changed management were more likely to have had GI tract surgery (69% vs 57 %, p = 0.021), higher white blood cell (WBC) (16.4 [13.1-20.5] vs 15.1 [9.9-19.5], p = 0.002), more hours between CT and laparotomy (184 [141-245] vs 162 [89-230], p = 0.002), and lower mortality (2% vs 8 %, p = 0.008). In-hospital mortality was 5 %; none were PE-related. Predictors of clinical intervention required based on CT imaging were GI tract injury (AOR: 1.65, p = 0.0182), and elevated WBC (AOR: 1.038, p = 0.010 Conclusion Saddle and lobar PE incidence post-trauma laparotomy is low. SIRS-type symptoms prompting postoperative CT commonly have no procedural or antibiotic requirement. Postoperative decompensation is more likely related post-operative complications, and less likely a PE.

O blood type is not associated with worse coagulopathy or outcome in exsanguinating trauma.

BACKGROUND: Despite improving understanding of trauma-induced coagulopathy (TIC), mortality and morbidity due to exsanguinating trauma remain high. Increased complications due to hemorrhage have been reported in blood group O, possibly due to reduced levels of von Willebrand factor (vWF). METHODS: An urban level 1 adult trauma center registry was retrospectively queried. Patients receiving ≥6 units of pRBC within 4 â€‹h of presentation were included. Patient demographics, admission labs and outcomes were obtained. Univariate and multiple logistic regression analyses were performed. RESULTS: 562 patients were identified. There were no significant differences in demographics, admission labs, or outcome between different ABO groups. After adjustment, Type A patients were more likely to be hypocoagulable compared to Type O patients (p â€‹= â€‹0.014). No mortality differences were seen between ABO types in multiple regression analysis. CONCLUSIONS: No outcome or mortality differences were seen between ABO types, therefore factors other than vWF expression should be considered to explain coagulopathy in trauma patients.

Clinical Implications of Over- and Under-Triage Using Need for Trauma Intervention and Cribari Indices.

BACKGROUND: Need for Trauma Intervention (NFTI) score was proposed to help identify injured trauma patients while minimizing under (UT) and over triage (OT). Using a national database, we aimed to describe UT and OT of NFTI vs standard Cribari method (CM) and hypothesized triage sensitivity remains poor. METHODS: The 2021 Trauma Quality Improvement Program (TQIP) database was queried. Demographics, mechanism, verification level, interfacility transfer (IF), and level of activation were collected. Patients were stratified by both NFTI [+ vs -] and CM [Injury severity score (ISS) < 15 vs > 15]. UT was defined as NFTI + or ISS >15 without full trauma activation. RESULTS: 1,030,526 patients were identified in TQIP. 84,969 were UT and 97,262 were OT using NFTI while 94,020 were UT and 108,823 were OT using CM. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of NFTI is 49%, 89%, 45%, and 90%, respectively vs 43%, 87%, 39%, and 89% of CM, respectively. Age was higher in the UT group using both scores (52 vs 42, P < .0001 and 54 vs 42, P < .0001, respectively). Using MLR, level 2 and 3 verification, blunt mechanism, female, IF, and older age were associated with UT in both NFTI and CM. Level 1 verification, penetrating mechanism, male, no IF, and younger age were associated with OT. CONCLUSIONS: Current prehospital triage criteria have poor sensitivity for identifying severely injured trauma patients by both NFTI and CM. UT increases as age of the patient increases. Further studies are needed to improve triage.

Isolated facial fractures transferred for higher level of care.

BACKGROUND: Isolated facial fractures (IFF) have been identified as overtriaged injuries in multiple single-center studies. We sought to describe IFF in a national database. METHODS: The 2019 Trauma Quality Improvement Program database was queried for all patients with facial fractures and Abbreviated Injury Score<1 for other body regions. Descriptive statistics were performed. RESULTS: Of 1,097,190 trauma patients, 36,077 (3.3%) had IFF. Median age was 39 [26-89], 92% had blunt mechanism, median Glasgow Coma Scale 15 [15-15], and vital signs were normal (ED systolic blood pressure 137 [125-153], ED pulse 86 [73-99]). 0.3% required unplanned intubation. 25.7% underwent operation after a median interval 26.4 [14.4-47.9] hours. IFF patients represented 4.4% of interfacility transfers and were more likely to have been transferred (34.4% vs 25%, p < 0.001). Hospital stay was 3 [2-4] days. CONCLUSIONS: IFF are rarely surgical emergencies and frequently nonoperative, yet are disproportionately represented among transfers. IFFs may represent an opportunity for outpatient follow-up or telehealth consultation to decrease resource utilization.

Delayed Tracheostomy After Cervical Fixation is Not Associated With Improved Outcomes: A Trauma Quality Improvement Program Analysis.

BACKGROUND: Patients with unstable cervical spine (C-spine) fractures are at a significant risk of respiratory failure. There is no consensus on the optimal timing of tracheostomy in the setting of recent operative cervical fixation (OCF). This study evaluated the impact of tracheostomy timing on surgical site infections (SSIs) in patients undergoing OCF and tracheostomy. METHODS: Trauma Quality Improvement Program (TQIP) was used to identify patients with isolated cervical spine injuries who underwent OCF and tracheostomy between 2017 and 2019. Early tracheostomy (<7 days from OCF) was compared with delayed tracheostomy (≥7 days from OCF). Logistic regressions identified variables associated with SSI, morbidity, and mortality. Pearson correlations evaluated time to tracheostomy and length of stay (LOS). RESULTS: Of 1438 patients included, 20 had SSI (1.4%). There was no difference in SSI between early vs delayed tracheostomy (1.6% vs 1.2%, P = .5077). Delayed tracheostomy was associated with increased ICU LOS (23.0 vs 17.0 days, P < .0001), ventilator days (19.0 vs 15.0, P < .0001), and hospital LOS (29.0 vs 22.0 days, P < .0001). Increased ICU LOS was associated with SSI (OR 1.017; CI 0.999-1.032; P = .0273). Increased time to tracheostomy was associated with increased morbidity (OR 1.003; CI 1.002-1.004; P < .0001) on multivariable analysis. Time from OCF to tracheostomy correlated with ICU LOS (r (1354) = .35, P < .0001), ventilator days (r (1312) = .25, P < .0001), and hospital LOS (r (1355) = .25, P < .0001). CONCLUSION: In this TQIP study, delayed tracheostomy after OCF was associated with longer ICU LOS and increased morbidity without increased SSI. This supports the TQIP best practice guidelines recommending that tracheostomy should not be delayed for concern of increased SSI risk.

Cryoprecipitate use during massive transfusion: A propensity score analysis.

INTRODUCTION: Cryoprecipitate is frequently administered as an adjunct to balanced transfusion in the setting of traumatic hemorrhage. However, civilian studies have not demonstrated a clear survival advantage, and prior observational studies noted selection bias when analyzing cryoprecipitate use. Additionally, due to the logistics involved in cryoprecipitate administration, it is inconsistently implemented alongside standardized massive transfusion protocols. This study aims to evaluate the effects of early cryoprecipitate administration on inpatient mortality in the setting of massive transfusion for exsanguinating trauma and to use propensity score analysis to minimize selection bias. METHODS: The registry of an urban level 1 trauma center was queried for adult patients who received at least 6 units of packed red blood cells within 4 h of presentation. Univariate analysis, multiple logistic regression, and propensity score matching were performed. RESULTS: 562 patients were identified. Patients with lower median RTS (6.86 (IQR 4.09-7.84) vs 7.6 (IQR 5.97-7.84), P<0.01), decreased Glasgow coma scale (12 (IQR 4-15) vs 15 (IQR 10-15), P<0.01), and increased lactate (7.5 (IQR 4.3-10.2) vs 4.9 (IQR 3.1-7.2), P<0.01) were more commonly administered cryoprecipitate. Mortality was greater among those who received cryoprecipitate (40.2% vs 23.7%, p<0.01) on univariate analysis. Neither multiple logistic regression (OR 0.917; 95% confidence interval 0.462-1.822; p = 0.805) nor propensity score matching (average treatment effect on the treated 2.3%, p = 0.77) revealed that cryoprecipitate administration was associated with a difference in inpatient mortality. CONCLUSIONS: Patients receiving cryoprecipitate within 4 h of presentation were more severely injured at presentation and had increased inpatient mortality. Multivariable logistic regression and propensity score analysis failed to show that early administration of cryoprecipitate was associated with survival benefit for exsanguinating trauma patients. The prospect of definitively assessing the utility of cryoprecipitate in exsanguinating hemorrhage warrants prospective investigation.

Rapid Detection of Significant Traumatic Brain Injury Requiring Emergency Intervention.

Moderate and severe traumatic brain injuries (TBI) are a major cause of severe morbidity and mortality; rapid diagnosis and management allow secondary injury to be minimized. Traumatic brain injury is only one of many potential causes of altered mental status; head computed tomography (HCT) is used to definitively diagnose TBI. Despite its widespread use and obvious importance, interpretation of HCT images is rarely covered by formal didactics during general surgery or even acute care surgery training. The schema illustrated here may be applied in a rapid and reliable fashion to HCT images, expediting the diagnosis of clinically significant traumatic brain injury that warrants emergent medical and surgical therapies to reduce intracranial pressure. It consists of 7 normal anatomic structures (cerebrospinal fluid around the brain stem, open fourth ventricle, "baby's butt," "Mickey Mouse ears," absence of midline shift, sulci and gyri, and gray-white differentiation). These 7 features can be seen even as the CT scanner obtains images, allowing the trauma team to expedite medical management of intracranial hypertension and pursue neurosurgical consultation prior to radiologic interpretation if the features are abnormal.

Outcomes and complications for portal vein or superior mesenteric vein injury: No improvement in the era of damage control resuscitation.

INTRODUCTION: Portal vein (PV) and superior mesenteric vein (SMV) injuries are lethal. We hypothesised outcomes have improved with modern trauma care. METHODS: We reviewed patients presenting to our Level 1 trauma centre over ten-years with PV/SMV injuries, analysing physiology, operative management, associated injuries, and outcomes. RESULTS: Twenty-four patients had 7 PV and 15 SMV injuries, 2 had both; all had operative exploration. Sixty-seven percent had penetrating trauma. While many had normal vitals, profound acidosis was common. All patients had ≥2 additional abdominal injuries, liver most common (50%). Additional abdominal vascular injuries were more common in non-survivors than survivors: IVC 46% vs 22%, common hepatic artery 20% vs 0%, SMA 26% vs 11%. The mean injury severity score (ISS) was 32.4, and the mean new injury severity score (NISS) was 44.5. Mortality was 63%. Eleven patients died from exsanguination, two from SMV thrombosis, and two from sequelae of other injuries. All survivors had venorrhaphy, as did 8 non-survivors. Non-survivors were also shunted; had ligation; or bypass, shunting, and ligation. Three exsanguinated prior to repair. Two survivors had SMV related complications. One with proximal SMV injury developed severe venous congestion and multiple enterocutaneous fistulae. Another developed an arterioportal fistula, managed with embolisation and percutaneous portal vein stenting. CONCLUSION: Despite advances (REBOA, damage control surgery and resuscitation, liberal use of ED thoracotomy), PV and SMV injuries remain lethal. Injuries to other structures are ubiquitous. Early exsanguination is the major cause of death. All survivors had successful venorrhaphy; those who required more complex repairs died. Compromised mesenteric venous flow causes morbidity and mortality.

Statewide Analysis of Peptic Ulcer Disease: As Hospitalizations Decrease, Procedural Volume Remains Steady.

Hospitalizations for peptic ulcer disease (PUD) have decreased since the advent of specific medical therapy in the 1980s. The authors' clinical experience at a tertiary center, however, has been that procedures to treat PUD complications have not declined. This study tested the hypothesis that despite decreases in PUD hospitalizations, the volume of procedures for PUD complications has remained consistent. The study population included all inpatient encounters in the state of Maryland from 2009 to 2014 with a primary ICD-9 diagnosis code for PUD. Data on annual patient volume, demographics, anatomic location, procedures, complications, and outcomes were collected, and PUD prevalence rates were calculated. The study population consisted of the state's entire population, not a sample; statistical analysis was not applied. Hospitalizations for PUD declined from 2,502 in 2009 to 2,101 in 2014, whereas the percentage of hospitalizations with procedures increased from 27.1 to 31.5 per cent. Endoscopy was performed in 19.8 per cent of hospitalizations, operation in 9.4 per cent, and angiography in 1.3 per cent. Of 13,974 inpatient encounters, 30 per cent had at least one inhospital complication. Overall inpatient mortality was 2.2 per cent. PUD hospitalizations are declining in Maryland, mirroring national trends. A subset of patients continue to need urgent procedures for PUD complications, including nearly 10 per cent needing operation. Inpatient mortality among patients admitted for PUD was 2.2 per cent, congruent with other studies. Despite the efficacy of modern medical therapy, these data underscore the importance of teaching surgical residents the cognitive and operative skills necessary to manage PUD complications.

Is thromboelastography (TEG)-based resuscitation better than empirical 1:1 transfusion?

Thomboelastography (TEG) is a whole blood measure of coagulation which was originally described in the 1950s. However, it has only been in the last few decades that assays have become accessible and viable as a point-of-care test. Following the observation that hemorrhagic shock is associated with an intrinsic coagulopathy, TEG has been used as a method of diagnosing specific coagulation defects in order to direct individualized blood products resuscitation. An alternative transfusion strategy is the administration of fixed ratio products, a paradigm borne out of military experience. It is unknown which strategy is superior and this topic was debated at the 36th Annual Point/Counterpoint Acute Care Surgery Conference. The following article summarizes the discussants points of view along with a summary of the evidence. LEVEL OF EVIDENCE: Level III.

Epidemiology of road traffic injury patients presenting to a tertiary hospital in Hyderabad, India.

BACKGROUND: Road traffic injuries kill more people in India than in any other country in the world, and these numbers are rising with increasing population density and motorization. Official statistics regarding road traffic injuries are likely subject to underreporting. This study presents results of a surveillance program based at a public tertiary hospital in Hyderabad, India. METHODS: All consenting patients who presented to the casualty ward after a road traffic injury over a 9-month period were enrolled. Interviews were performed and data abstracted from clinical records by trained research assistants. Data included demographics, injury characteristics, risk factors, safety behaviors, and outcomes. RESULTS: A total of 5,298 patients were enrolled; their mean age was 32.4 years (standard deviation 13.8) and 87.3% were men; 58.2% of patients were injured while riding a motorcycle or scooter, 22.5% were pedestrians, and 9.2% used motorized rickshaws. The most frequent collision type was skid or rollover (40.9%). Male victims were younger than female victims and were overrepresented among motorized 2-wheeler users. Patients were most frequently injured from 1600 to 2400. A total of 27.3% of patients were admitted. Hospital mortality was 5.3%, and 48.2% of deaths were among motorized 2-wheeler users. CONCLUSION: This is one of the few prospective, hospital-based studies of road traffic injury epidemiology in India. The patient population in this study was similar to prior hospital-based studies. When compared to government surveillance systems, this study showed motorized 2-wheeler users to be more frequently represented among the overall population and among fatalities. Further research should be done to develop interventions to decrease mortality associated with 2-wheeled vehicles in India.

Peritoneal free air due to evacuation of pneumobilia in blunt abdominal trauma.

Pneumobilia is mostly observed on computed tomography (CT) following surgical biliary-enteric anastomosis and biliary manipulation through endoscopic procedures. Although pneumobilia can be seen in pathological conditions, post-surgical pneumobilia is typically not associated with morbidity. In the present article, we report a case in which blunt abdominal trauma led to the evacuation of pre-existing pneumobilia causing pneumoperitoneum. Given that the subsequent laparotomy proved to be non-therapeutic, this report adds to the few cases of intra-peritoneal free air not helped by surgical intervention.
