RESUMEN
BACKGROUND: Hospitalized patients are well described as having a high prevalence of constipation. While the risks associated with constipation in trauma patients are well known, the prevalence rate is not. OBJECTIVE: This study aims to measure the prevalence of constipation and associated risk factors in trauma patients. METHODS: This study is a single-center analytic cross-sectional study on constipation in hospitalized trauma patients aged 18-65 years, admitted from January 2021 to July 2021 to the trauma service at The Royal Melbourne Hospital, a Level I major trauma and teaching hospital servicing the state of Victoria, Australia. Exclusion criteria include patients with traumatic brain injury, blunt or penetrating abdominal or spinal injuries, pregnancy, and gastrointestinal comorbidities. RESULTS: A total of N = 99 patients were studied, of which n = 78 (78.8%) were male with a median (interquartile range) age of 46 years (33-58). The overall prevalence of constipation was 76%. The univariate analysis demonstrated higher constipation rates in males and patients with multisystem injuries. However, in the multivariate analysis, mode of toileting and mobility were not associated with constipation after adjusting for confounding factors. CONCLUSION: This study demonstrated a high prevalence of constipation in all trauma patients. There is a strong association between the development of constipation in patients with multisystem injuries when compared to those with single system.

BACKGROUND: The proliferation of electric scooters globally has been associated with an increase in related injuries and consequent economic burden. This study aims to assess the injury patterns and the economic impact associated with electric scooter use in Melbourne, Australia. METHODS: A retrospective cohort study was conducted using hospital and registry data from January 2022 to January 2023. Data collected included demographic details, alcohol and helmet use, injury type and severity, operative treatment provided, and direct medical costs. The economic impact (in AUD) of the patient's emergency presentation and hospital admission was calculated. RESULTS: During the study period, 256 electric scooter related injuries were recorded, comprising 247 riders and nine pedestrians. The majority of patients were males (69%) with a median age of 29.5 (15-78). Alcohol use was reported by 34% and helmet use by 33%. Injuries most commonly affected the upper limb (53%) and head (50%), with abrasions (75%) and fractures (48%) being the most common type of injury sustained. The total hospital cost was $1 911 062, and the median cost was $1321.66 per patient (IQR: $479.37-$5096.65). CONCLUSION: Electric scooter usage, as observed through patient presentations to the Royal Melbourne Hospital, is associated with a considerable number of injuries, primarily among young males, and an ensuing substantial economic burden. The findings underscore the urgent need for improved safety measures to minimize electric scooter-related injuries and their clinical and economic repercussions.

PURPOSE: Interhospital transfer of critically injured patients to a major trauma service reduces preventable death in major trauma. Yet some of those transferred die without intervention. These 'futile' interhospital trauma transfers (IHTs), and other potentially avoidable IHTs place enormous stress on families of trauma victims, can delay care, and incur great cost to public health resources. This study sought to characterise these IHTs using current state guidelines for interhospital transfer. METHODS: A retrospective cohort study was conducted using our institution's trauma registry from January 2016-December 2020. All adult patients transferred to our major trauma service were analysed. Futile IHTs were defined as death or transfer to hospice care without surgical, endoscopic, or radiological intervention, and without ICU admission, within 72 h of admission. Potentially avoidable IHTs were defined as all patients discharged alive without intervention or ICU care, and secondary over-triage patients are a subset of these patients who were discharged within 72 h of admission. Patient demographics, injuries, and treatments were categorised from electronic records and analysed. RESULTS: Of 2,837 IHTs, seven (0.2 %) met criteria for futility. The majority were female, median age of 80 (IQR 85-75) and had a median Injury Severity Score (ISS) of 16 (IQR 25.5-11.5). By contrast, 1391 patients (49 %) were classified as potentially avoidable and 513 (18 %) were considered secondary over-triage. The majority were male, median age of 43 (IQR 62-28), and had a median ISS of 9 (IQR 13-4). Of these potentially avoidable IHTs, 984 (70.7 %) were discharged directly home. CONCLUSION: Futile IHTs were infrequent, however over half of all trauma patients transferred from other hospitals were discharged without tertiary-level intervention. Trauma services should consider developing systems such as telehealth to support regional general and orthopaedic surgeons to co-manage lower risk trauma, particularly minor head and minor spinal trauma patients. This could be an integral part of safely reducing potentially avoidable IHTs and their associated costs while maintaining a low rate of preventable mortality in trauma.

BACKGROUND: Prehospital tourniquets (PHTQ) for trauma have been shown to be safe and effective in the military environment and in some civilian settings. However, the supporting civilian data are mostly from North America with a differing case mix and trauma system and may not be applicable to the Australian environment. The aim of this study is to describe our initial experience with PHTQ from safety and efficacy viewpoints. METHOD: Retrospective review of all patients with PHTQ from 1 August 2016 to 31 December 2019 was conducted. Data were matched from the RMH Trauma Registry and Ambulance Victoria Registry. Clinical presentation including prehospital observations, PHTQ times, limb outcomes and complications are described. RESULTS: Thirty-one cases met inclusion criteria, for whom median age was 37 (IQR: 23.9-66.3), median ISS 17 (13-34) and 80.6% were male. The majority (n = 19, 61.3%) were as a result of road traffic crash, and six (19.4%) from penetrating mechanisms, usually glass. Over a quarter (29.0%) suffered a traumatic amputation. The median prehospital SBP was 100 (IQR: 80-110), the median prehospital HR was 101 (IQR: 77.0-122.3) and was the median PHTQ time was 124 min (IQR: 47-243). Complications attributable to the tourniquet were seen in 4/30 cases (13.3%). CONCLUSION: This Australian series differs from North American civilian PHTQ series with a lower penetrating trauma rate and longer PHTQ times. Despite this, complication rates are within the published literature's range. Concerns regarding limited transferability of overseas studies to the Australian context suggests that ongoing audit is required.

OBJECTIVES: Drug and alcohol intoxication is common among injured patients altering trauma presentation and characteristics. However, uncertainty exists regarding the effect of intoxication on injury severity, as well as outcomes. The present study aims to provide an update on substance-use patterns and their association with traumatic presentation and outcome within a contemporary Australian context. METHODS: All major trauma patients captured in our centre's Trauma Registry between July 2010 and June 2020 were included. Demographic, injury characteristic, outcome and substance-use data were collected. Differences in injury severity and characteristics were explored using χ2 tests, while outcomes were modelled using adjusted binomial logistic regression. RESULTS: Among 9700 patients, 9% were drug-intoxicated prior to injury, while 9.4% were alcohol-intoxicated. Drug use almost tripled between 2010 (4.8%) and 2020 (13.3%), while alcohol intoxication fell, from 11.7% to 7.3%, over the same period. Although there were significant differences in trauma mechanism among intoxicated patients, group comparison found no difference in Injury Severity Score for any group. Regarding outcomes, all intoxication resulted in significantly greater odds (odds ratio 1.62-2.41) of ICU admission. No difference in mortality was found among individual substance-use groups; however, polysubstance-intoxicated patients had 3.52 times greater odds of dying (95% confidence interval 1.21-10.23) compared to non-intoxicated patients. CONCLUSION: Within this contemporary Australian population, we demonstrate escalating rates of drug intoxication and declining rates of alcohol intoxication prior to trauma. Intoxication was associated with more frequent violent and non-accidental injury, and despite no difference in severity, it was associated with worse outcomes.

BACKGROUND: Acute colonic pseudo-obstruction (ACPO) is a potentially highly morbid surgical complication. The incidence of ACPO following spinal trauma is unknown, but is likely higher than after elective spinal fusion. The purpose of this study was to establish the incidence of ACPO in patients with major trauma undergoing spinal fusion for unstable thoracic and lumbar fracture, and secondly, to characterize the nature of ACPO in this group, including treatment and complications. METHODS: A metropolitan hospital prospective trauma database was utilized to identify all patients from November 2015 to December 2021 meeting major trauma criteria and undergoing thoracic or lumbar spinal fusion for fracture. Individual records were then evaluated for occurrence of ACPO. ACPO was defined as radiologic evidence of colonic dilation without mechanical obstruction in symptomatic patients undergoing dedicated abdominal imaging. RESULTS: After exclusions, 456 patients with major trauma undergoing thoracic or lumbar spinal fusion were identified. ACPO occurred in 34-an incidence rate of 7.5%. There was no evidence of difference in terms of the spinal fracture type, level, surgical approach, or number of segments fused. There were no perforations; only 2 patients required colonoscopic decompression and none required surgical resection. CONCLUSIONS: ACPO occurred at a high frequency in this group of patients, although it required relatively simple treatment. High vigilance for ACPO should be maintained in trauma patients requiring thoracic or lumbar fixation, with a view to early intervention. The etiology driving the high rates of ACPO in this cohort is not understood and would benefit from further investigation.
RESUMEN
BACKGROUND: The COVID-19 pandemic has had a profound effect on the presentation and management of trauma at the Royal Melbourne Hospital, a level 1 adult major trauma service and a designated COVID-19 hospital. This study compares the changes in epidemiology and trauma patient access to emergency imaging and surgery during the pandemic response. METHODS: The population of interest was all trauma patients captured in the hospital's trauma registry from 16 March 2016 to 10 September 2020. Regression modelling assessed changes in mechanism and severity of the injury, and mortality during two lockdowns compared with the proceeding 4 years. Cases were matched with hospital administrative databases to assess mean time from admission to emergency computed tomography (CT) scan, operating theatre, length of stay (LOS) and immediate surgery (OPSTAT). RESULTS: Throughout 2020, the hospital treated 525 COVID-19 patients. Compared with previous years, there was up to 34% reduction in major trauma and a 28% reduction in minor trauma admissions during the pandemic (p < 0.05). Intensive care unit admissions were almost half of predicted. Some of the largest reductions were seen in motor vehicle crashes (49%) and falls (28%) (p < 0.05). Time to CT, surgery and immediate surgery (OPSTAT) showed no change and having a suspected COVID-19 diagnosis did not prolong any of these times except for the LOS. Mortality was similar to previous years. CONCLUSION: The COVID-19 pandemic has had widespread societal changes, resulting in a substantial decrease in trauma presentations. Despite COVID's immense impact on the hospital's trauma service, the quality of care was not impaired.

INTRODUCTION: Traumatic internal carotid artery (ICA) injuries are an uncommon complication of petrous temporal bone (PTB) fractures that can have devastating consequences of stroke, haemorrhage and death. Current guidelines suggest that all PTB fractures should be screened for blunt cerebrovascular injury, however clinical practice varies. The purpose of this study was to identify features associated with PTB fractures that increase the likelihood of ICA injury. METHODS: A retrospective cohort study was performed on all patients with PTB fractures who were investigated with computed-tomography angiography (CTA) scan admitted to a Level One Trauma Service in Melbourne, Australia from 2015-2020. Patient demographic and injury data were obtained from The Royal Melbourne Hospital Trauma Registry and medical records. Multivariate binomial logistic regression was performed to identify features associated with ICA injury. RESULTS: Out of 377 patients with 419 PTB fractures, 205 received a CTA scan and were included, identifying 22 ICA injuries (9.4%). The median age of ICA injuries was 33 (IQR 23-61), median Abbreviated Injury Scale (AIS) score for the head region was 5 (IQR 5-5) and the in-hospital mortality rate was 45.5%, mainly due to unsurvivable brain injury. Five patients (22.7%) developed ICA-specific complications of stroke or carotid-cavernous fistula. We identified five factors that were significantly associated with ICA injury. These included PTB fractures involving the carotid canal (OR 6.7, 95% CI 1.9-23.9, p=0.003), presenting with an initial GCS less than nine (OR 5.7, 95% CI 1.2-26.5, p=0.025) and increasing head AIS (OR 2.4, 95% CI 1.2-4.6, p=0.009). Mechanisms of injury that were associated with ICA injury were motor vehicle crash (OR 4.4, 95% CI 1.4-14.2, p=0.012) and motorbike crash (OR 4.6, 95% CI 1.2-18, p=0.029). CONCLUSION: Patients with PTB fractures and an additional feature of carotid canal involvement, presenting GCS less than nine, increasing head AIS indicative of severe head trauma or mechanism of injury by motor vehicle or motorbike crash, are at an increased risk of ICA injury and should be screened with a CTA scan.

BACKGROUND: External fixation is commonly used as a means of definitive fixation of pelvic fractures. Pin site infection is common, with some cases of osteomyelitis and inpatient nursing can be challenging. The aim of this study is to report the outcomes and complications of an alternative minimally invasive technique, known as INFIX, utilising spinal pedicle screws inserted into the supra-acetabular bone and connected by a subcutaneous rod. METHODS: A single-centre prospective case series was performed. The primary outcome measures were fracture stability and displacement at time of implant removal and intra- and post-operative complications. RESULTS: Twenty-one patients were recruited, with 85.7 % of fractures being lateral compression type. Mean follow-up was 342 days. Mean application time was 51 min (range 44-65). Nineteen were removed electively, with mean time to removal 109 days. All cases were stable with no displacement. Two cases were removed emergently, one due to wound infection and the other due to lateral femoral cutaneous nerve neuropathic pain. Twelve patients sustained a lateral femoral cutaneous nerve palsy, with 20/42 nerves being affected. Improvement in all lateral femoral cutaneous nerve symptoms were reported with removal. Nine patients developed asymptomatic heterotopic ossification, and there were three deep infections and one symptomatic due to the bar. CONCLUSIONS: Minimally invasive internal fixation with the INFIX for anterior pelvic ring fractures is an alternative to anterior external fixation. However, a higher rate of lateral femoral cutaneous nerve palsy is noted, and the implant is not well tolerated by all patients. Further studies are required to define fracture types and patients best suited to the technique and how LFCN complications may be minimised. TRIAL REGISTRATION: ACTRN12616001421426 .

BACKGROUND: Penetrating or blunt injury to the biliary tree remains a rare complication of trauma occurring in 0.1% of trauma admissions. Because of the different presentations, sites of biliary tract injury, and associated organ injury, there are many possible management pathways to be considered. METHODS: A retrospective analysis of prospectively gathered data was performed for all gallbladder and biliary tract injuries presenting to the trauma service or hepatobiliary unit of the Royal Melbourne Hospital between January 1, 1999, and March 30, 2011. RESULTS: There were 33 biliary injuries in 30 patients (0.1%) among 26,014 trauma admissions. Three of the 30 patients (10%) died. Of 10 gallbladder injuries, 8 were managed with cholecystectomy. There were 23 injuries to the biliary tree. Fourteen patients had injuries to the intrahepatic biliary tree of which seven involved segmental ducts. Of these, four segmental duct injuries required hepatic resection or debridement. Nine patients had injury to the extrahepatic biliary tree of which five required T-tube placement ± bilioenteric anastomosis and one a pancreaticoduodenectomy. CONCLUSION: Biliary injury is a rare but important consequence of abdominal trauma, and good outcomes are possible when a major trauma center and hepatopancreaticobiliary service coexist. Cholecystectomy remains the gold standard for gallbladder injury. Drainage with or without endoscopic stenting will resolve the majority of intrahepatic and partial biliary injuries. Hepaticojejunostomy remains the gold standard for complete extrahepatic biliary disruption. Hepatic and pancreatic resection are only required in the circumstances of unreconstructable biliary injury. LEVEL OF EVIDENCE: Therapeutic study, level V.
