RESUMO
BACKGROUND: Postinjury multiple organ failure (MOF) is the leading cause of late death in trauma patients. Although MOF was first described 50 years ago, its definition, epidemiology, and change in incidence over time are poorly understood. We aimed to describe the incidence of MOF in the context of different MOF definitions, study inclusion criteria, and its change over time. METHODS: Cochrane Library, EMBASE, MEDLINE, PubMed, and Web of Science databases were searched for articles published between 1977 and 2022 in English and German. Random-effects meta-analysis was performed when applicable. RESULTS: The search returned 11,440 results, of which 842 full-text articles were screened. Multiple organ failure incidence was reported in 284 studies that used 11 unique inclusion criteria and 40 MOF definitions. One hundred six studies published from 1992 to 2022 were included. Weighted MOF incidence by publication year fluctuated from 11% to 56% without significant decrease over time. Multiple organ failure was defined using four scoring systems (Denver, Goris, Marshall, Sequential Organ Failure Assessment [SOFA]) and 10 different cutoff values. Overall, 351,942 trauma patients were included, of whom 82,971 (24%) developed MOF. The weighted incidences of MOF from meta-analysis of 30 eligible studies were as follows: 14.7% (95% confidence interval [CI], 12.1-17.2%) in Denver score >3, 12.7% (95% CI, 9.3-16.1%) in Denver score >3 with blunt injuries only, 28.6% (95% CI, 12-45.1%) in Denver score >8, 25.6% (95% CI, 10.4-40.7%) in Goris score >4, 29.9% (95% CI, 14.9-45%) in Marshall score >5, 20.3% (95% CI, 9.4-31.2%) in Marshall score >5 with blunt injuries only, 38.6% (95% CI, 33-44.3%) in SOFA score >3, 55.1% (95% CI, 49.7-60.5%) in SOFA score >3 with blunt injuries only, and 34.8% (95% CI, 28.7-40.8%) in SOFA score >5. CONCLUSION: The incidence of postinjury MOF varies largely because of lack of a consensus definition and study population. Until an international consensus is reached, further research will be hindered. LEVEL OF EVIDENCE: Systematic Review and Meta-analysis; Level III.

OBJECTIVE: Describe the characteristics and predictors of mortality for patients who spend more than 24 h in the ED waiting for an in-patient bed and compare baseline clinical and demographic characteristics between tertiary and non-tertiary hospitals. METHODS: This was a state-wide analysis data linkage analysis of adult (age >16 years) ED presentations across New South Wales from 2019 to 2020. Cases were included if their mode of separation from ED indicated admission to an in-patient unit including critical care ward and their ED length of stay was greater than or equal to 24 h. Cases were categorised by service-related groups based on principle diagnosis. RESULTS: A total of 26 854 eligible cases were identified. The most common diagnosis groups were psychiatry, cardiology and respiratory. The odds ratio (OR) for 30-day all-cause mortality in admitted patients with an ED length of stay greater than 24 h were highest in those aged >75 years (OR 15.18, 95% confidence interval [CI] 9.99-23.07, P < 0.001), oncology (OR 10.45, 95% CI 7.93-13.77, P < 0.001) and haematology patients (OR 2.95, 95% CI 2.01-4.33, P < 0.001). CONCLUSION: Interventions and models of care to address ED access block need to focus on mental health patients, older patients particularly those with cardiorespiratory illness and oncology and haematology patients for whom risk of mortality is disproportionately higher.

BACKGROUND: Hemorrhage is a leading cause of preventable death in trauma. Prehospital medical teams can streamline access to massive transfusion and definitive hemorrhage control by alerting in-hospital trauma teams of suspected life-threatening bleeding in unstable patients. This study reports the initial experience of an Australian "Code Crimson" (CC) pathway facilitating early multidisciplinary care for these patients. METHODS: This data-linkage study combined prehospital databases with a trauma registry of patients with an Injury Severity Score greater than 12 between 2017 and 2019. Four groups were created; prehospital CC activation with and without in-hospital links and patients with inpatient treatment consistent with CC, without one being activated. Diagnostic accuracy was estimated using capture-recapture methodology to replace the missing cell (no prehospital CC and Injury Severity Score < 12). RESULTS: Of 72 prehospital CC patients, 50 were linked with hospital data. Of 154 potentially missed patients, 42 had a prehospital link. Most CC patients were young men who sustained blunt trauma and required more prehospital interventions than non-CC patients. Code Crimson patients had more multisystem trauma, especially complex thoracic injuries (80%), while missed CC patients more frequently had single organ injuries (59%). Code Crimson patients required fewer hemorrhage control procedures (60% vs. 86%). Lower mortality was observed in CC patients despite greater hospital and intensive care unit length of stay. Despite a low sensitivity (0.49; 95% confidence interval [CI], 0.38-0.61) and good specificity (0.92; 95% CI, 0.86-0.96), the positive likelihood ratio was acceptable (6.42; 95% CI, 3.30-12.48). CONCLUSION: The initiation of a statewide CC process was highly specific for the need for hemorrhage control intervention in hospital, but further work is required to improve the sensitivity of prehospital activation. Patients who had a CC activation sustained more multisystem trauma but had lower mortality than those who did not. These results guide measures to improve this pathway. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

PURPOSE: To describe the characteristics of major injury and identify determinants of long-term unplanned readmission and mortality after self-inflicted and non-self-inflicted injury to inform potential readmission screening. METHOD: A retrospective cohort study of 11,269 individuals aged ≥ 15 years hospitalised for a major injury during 2013-2017 in New South Wales, Australia. Unplanned readmission and mortality up to 27-month post-injury were examined. Logistic regression was used to examine predictors of unplanned readmission. RESULTS: During the 27-month follow-up, 2700 (24.8%) individuals with non-self-inflicted and 98 (26.1%) with self-inflicted injuries had an unplanned readmission. Individuals with an anxiety-related disorder and a non-self-inflicted injury who were discharged home were three times more likely (OR: 3.27; 95%CI 2.28-4.69) or if they were discharged to a psychiatric facility were four times more likely (OR: 4.11; 95%CI 1.07-15.80) to be readmitted. Compared to individuals aged 15-24 years, individuals aged ≥ 65 years were 3 times more likely to be readmitted (OR 3.12; 95%CI 2.62-3.70). Individuals with one (OR 1.60; 95%CI 1.39-1.84) or ≥ 2 (OR 1.88; 95%CI 1.52-2.32) comorbidities, or who had a drug-related dependence (OR 1.88; 95%CI 1.52-2.31) were more likely to be readmitted. The post-discharge age-adjusted mortality rate following a self-inflicted injury (35.6%; 95%CI 29.9-41.8) was higher than for individuals with a non-self-inflicted injury (11.0%; 95%CI 10.4-11.8). CONCLUSIONS: Unplanned readmission after injury is associated with injury intent, age, and comorbid health. Screening for anxiety and drug-related dependence after major injury, accompanied by service referrals and post-discharge follow-up, has potential to prevent readmission.

OBJECTIVE: The study aims to determine whether ED presentation volume or hospital occupancy had a greater impact on ED performance before and during the COVID-19 health response at a tertiary referral hospital in Sydney, Australia. METHODS: Single centre time series analysis using routinely collected hospital and ED data from January 2019 to September 2020. The primary outcome was ED access block measured by emergency treatment performance (ETP; i.e. percentage of patients who were discharged or transferred to a ward from ED within 4 h of ED arrival time). Secondary outcomes were hospital occupancy, elective theatre cases and ambulance ramping. Multivariate time series analysis was performed using vector autoregression, to model effects of changes in various endogenous and correlated variables on ETP. RESULTS: There was an increase in ETP, drop in ED presentations and decrease in hospital occupancy between April and June 2020. Elective surgery and hospital occupancy had significant effects up to 2 days prior on ETP, while there were no significant effects of either ED or ambulance presentations on ETP. Hospital occupancy itself increased with ED presentations after 2-4 days and decreased with elective surgery after 1 day. Shocks (a one standard deviation increase) in hospital occupancy had a peak impact nearly two times greater compared to ED presentations (-1.43, 95% confidence interval -1.92, -0.93 vs -0.73, 95% confidence interval -1.21, -0.25). CONCLUSION: The main determinants of the reduction of ED overcrowding and access block during the pandemic were associated with reductions in hospital occupancy and elective surgery levels, and more research is required to assess more complex associations beyond the scope of this manuscript.

OBJECTIVE: To determine specific patient, clinical and service factors associated with increased ED length of stay and investigate whether prolonged ED length of stay, as measured by emergency treatment performance (ETP) non-compliance, is an independent predictor of all cause 30-day mortality for patients presenting to, and admitted from ED. METHODS: This was a retrospective analysis of linked state-wide emergency, inpatient and death data from New South Wales. All patients who presented to a tertiary level public hospital (level 5 or 6) ED and admitted to an in-patient unit were included. Outcomes were the proportion of admitted patients who met ETP targets, and 30-day all-cause mortality. RESULTS: A total of 697 600 eligible cases were identified and analysed. The odds of meeting ETP benchmarks were 62% lower in those with complex or multiple medical comorbidities (odds ratio 0.38, 95% confidence interval 0.37-0.40, P < 0.001) compared with patients with no medical comorbidities. Admission under psychiatry, surgical and oncology service-related groups were associated with decreased ETP. The hazard ratio for 30-day all-cause mortality over time was 28% higher in those not meeting ETP benchmarks after adjusting for age, triage category, comorbidities, ICU and service-related group (hazard ratio 1.28, 95% confidence interval 1.26-1.30, P < 0.001). CONCLUSION: Patients with complex and multiple medical comorbidities, and those admitted under certain service-related groups such as psychiatry, surgery and oncology were found to have poorer ETP performance. Overall, failure to meet ETP was associated with increased mortality after adjusting for age, case-mix, comorbidities and acuity.

OBJECTIVES: To describe the trend in major trauma surgical procedures and interventional radiology in major trauma patients in Australia over the past 6 years. METHODS: This was a retrospective review of adult major trauma (Injury Severity Score greater than 15) patients using the New South Wales Statewide Trauma Registry between 2009 and 2014. Major trauma surgical procedures were classified into abdominal, neurosurgery, cardiothoracic and interventional radiology. The proportion of patients undergoing such procedures per year was the outcome of interest. RESULTS: There were around ten thousand cases analysed. The proportion of cases undergoing interventional radiology procedures increased from 1% in 2009 to around 6% in 2014. Other major trauma surgical procedures remained stable. Only around 100 laparotomies were performed in 2014. The predictors of having an IR procedure performed were increasing from 2009 (OR 1.5 95% CI 1.4, 1.6 p < 0.001), hypotension (OR 1.5 95% CI 1.1, 2.1 n = 0.01), severe abdominal injury (OR 4.2 95% CI 3.2, 5.3 p < 0.001) and lower limb (including pelvic) injury (OR 3.8 95% CI 3.0, 4.7 p < 0.001). CONCLUSION: There has been a rapid increase in the use of interventional radiology over the past few years which will need to be addressed in future trauma service planning and models of care.

BACKGROUND: The rate of hospitalization in elderly patients because of falls is increasing. The objective of this study was to investigate long-term trends in injury profiles of low-energy falls and to identify injuries associated with need for in-patient rehabilitation. METHODS: A single-centre retrospective study was performed at an inner city Major Trauma Centre in Sydney. Trauma registry data were obtained from patients who were 65 years of age or over with low-energy falls (trip and fall from height ≤ 1 m, including falls from standing) from the trauma registry between January 2000 and December 2011. Demographic data, time and date of presentation and injury characteristics were collected. Outcomes of interests were proportions of hip fractures, head injuries and discharge to in-patient rehabilitation facilities. RESULTS: A total of 4964 cases were identified. There was a 6.5% per annum decrease in the proportion of elderly patients with low-energy falls who sustained hip fractures compared with a relative increase in severe head injuries, 5.7% per annum. Around 25% of patients were transferred to in-patient rehabilitation. Severe head injuries and lower-limb injuries were the two injuries most associated with transfer to in-patient rehabilitation. CONCLUSION: In elderly patients with low-energy falls, a significant decrease in hip fractures was associated with a rise in severe head injuries over the past decade.

INTRODUCTION: Alcohol use is an important contributor to injuries. Simple bedside tools to identify trauma patients with potentially harmful drinking may assist in brief intervention efforts in clinical practice. The objective of the study was to determine and compare the accuracy of alcohol use disorders identification test (AUDIT) and an abbreviated version of this test, in the detection of hazardous drinking. METHODS: A cross-sectional study of a convenience sample of admitted trauma patients at a single Australian major trauma centre. Eligible patients completed the AUDIT. AUDIT survey responses were scored in two ways, using the full form scale and secondly an abbreviated (AUDIT C) scale which uses only the first 3 questions. AUDIT and AUDIT-C scores were then evaluated with respect to the primary study measure; the detection of hazardous alcohol consumption based on a full alcohol consumption history. Sensitivities for each relevant score were calculated and receiver operator characteristic (ROC) curve analysis was used to determine test accuracy. RESULTS: During the study period, 523 trauma admissions were identified and of these 146 (28%) were screened. The optimum cut off scores for AUDIT and AUDIT-C were 8 and 5 respectively corresponding to sensitivities of 88% and 91% and both tests had excellent overall accuracy for the detection of hazardous alcohol consumption. There was no significant difference between AUDIT-C and AUDIT performance (p=0.395) (AUDIT-C AUROC 0.96 95%CI 0.93, 0.99). CONCLUSION: AUDIT-C appears to be a potentially useful screening tool for use trauma centres, but that further research with larger samples is required.

OBJECTIVE: This study aimed to determine the relative effect of elderly patients and increasing injury severity on acute hospital costs and inpatient length of stay. METHODS: A prospective study of all trauma team activations at a single inner city trauma centre was conducted over a 1-year period. Costs were imputed using Australian Refined Diagnosis-Related Groups. Costs and inpatient length of stays were compared between elderly (age ≥65 years) and non-elderly patients. Relative effects of increasing injury severity score (ISS) and age categories were modelled using generalized linear regression. RESULTS: Over the study period, 1096 consecutive patients were studied. Falls were the most common mechanism and contributed the highest proportion of aggregate costs. There was a moderately high correlation between cost and ISS (Spearman's rank correlation coefficient 0.65, P < 0.001). Median costs for elderly patients were around three times higher than that for non-elderly patients and median length of stay was over twice that of non-elderly patients (7 days versus 3 days, P < 0.001). After adjusting for injury severity, the predicted costs of elderly trauma patients were around 30% higher compared with non-elderly patients. An increasing effect of injury severity on cost was observed across minor and major trauma. CONCLUSION: Both injury severity and elderly patients have a significant impact on acute hospital costs across the spectrum of major and minor trauma.

BACKGROUND: Elderly patients with major trauma are an increasingly important public health concern. The objective of the study was to describe the long term trend in patients aged 65 years and older with major trauma. METHODS: A retrospective single centre trauma registry study conducted at an inner city Major Trauma Centre in Sydney. Data on patients aged 65 years or older with major trauma (Injury Severity Score greater than 15) presenting between 1991 and 2010 were extracted from the data registry. Demographic data, mechanism of injury, injury severity scores and outcomes were collected. Study outcomes were proportion of total major trauma volume due to patients aged 65 years and older, in hospital mortality and total beddays occupied per year. RESULTS: The proportion of major trauma volume due to older patients increased by 4.9% per year currently accounting for a third of major trauma volume. The proportion of major trauma in older patients due to falls has also increased. Standardised mortality rates have declined by 2.2% per year. CONCLUSION: There has been a disproportionate increase in the proportion of major trauma due to older patients at this institution over the past twenty years. If this trend continues, it is likely to have significant impacts on future hospital and rehabilitation resources.

OBJECTIVE: Clinical handover is a critical point in medical care in the ED, which can contribute to adverse effects for patient care and staff workloads. Over a 4 and a half months in a tertiary referral hospital ED, a centralized whiteboard handover was performed followed by a multidisciplinary review of each patient. This round was referred to as the 'Cow Round'. METHODOLOGY: This observational study used a standardized feedback survey of clinicians leading each Cow Round. The survey asked participants in the round to report issues found, which were not handed over during the centralized whiteboard handover. Data were analysed for the number of issues identified, the type of issue identified, and to determine if there was a relationship between the number of issues reported and patients in the department. RESULTS: 204 surveys met inclusion criteria. Clinical issues not handed over at the standard whiteboard round were found in 64% of Cow Rounds. Of the 2411 patients reviewed on Cow Rounds, 14.1% had at least one clinical issue not handed over during the whiteboard round. A mean of 2.2 issues per round (95% CI 1.9-2.5) were found. Pearson correlation found a relationship between the number of issues identified and the total number of patients in the department (r= 0.246 P= 0.005). CONCLUSION: Review of patients led by a senior member of medical staff, at the patient bedside enables the timely identification and management of issues not communicated during the whiteboard handover process. This review is important when more patients are receiving treatment in the department.

OBJECTIVE: The authors previously developed a dynamic and integrated electronic decision support system called ACAFE (Asthma Clinical Assessment Form and Electronic decision support). The objective of this present study was to evaluate the effectiveness of this system on asthma management and documentation in an ED. METHOD: Observational study using a pre- and post-intervention design, comparing patients managed using ACAFE after its implementation with historical controls. A systematic data abstraction process was used to compare patient records. RESULTS: A total of 50 patients were enrolled in the study group. These were compared with 50 historical controls. Use of ACAFE was associated with significantly higher rates of documentation of asthma severity (98% vs 18%, P < 0.01), as well as other clinically important variables, such as asthma precipitants, intensive care admission history and smoking history. ACAFE was also associated with significantly higher rate of asthma discharge plan documentation (76% vs 16%, P < 0.01), and this remained significant after adjustment for triage category and seniority of treating doctor in a regression model. CONCLUSION: The use of this decision support system in patients presenting to emergency with asthma was associated with improvements in clinical documentation and discharge management plans. Electronic decision support systems developed collaboratively with clinicians should play an important part of system-wide efforts to improve guideline adherence and compliance in ED.

OBJECTIVE: The importance of immediate versus delayed pulmonary contusions among severely injured blunt trauma patients is unknown. We hypothesized that patients with pulmonary contusions apparent on initial chest radiographs have higher rates of mortality and acute respiratory distress syndrome than patients who have delayed radiographic changes of pulmonary contusions. DESIGN: Retrospective cohort study. SETTING: Level 1 designated trauma centre in Ontario Canada. METHODS: Eligible cases were identified through the hospital trauma registry over a 5-year period. All intubated severe trauma patients (ISS ≥ 16) with a discharge diagnosis of pulmonary contusion who presented within 2 h of injury time, were included. All cases had chest CT performed within 24 h of admission with reported findings consistent with pulmonary contusions. Patients with pulmonary contusions apparent on initial chest radiographs (CXR+) were compared with patients with delayed initial radiographic findings (CXR-). Primary outcomes were assessed by logistic regression controlling for covariates of interest. RESULTS: A total of 135 intubated trauma patients with pulmonary contusions were identified over the study period. Only 52% of these patients had contusions apparent on initial chest radiograph. The overall mortality was higher in CXR+ group compared with those in CXR- group (43% vs. 25% p = 0.02). In multivariable analyses controlling for injury severity, age, sex and head injury, the CXR+ group was associated with significantly increased odds of mortality and ARDS (odds ratio for CXR+ vs. CXR- 4.19, 95%CI 1.54-11.45, p < 0.01). CONCLUSION: Amongst intubated blunt trauma patients with confirmed pulmonary contusions diagnosis, an initial chest radiograph that reveals immediate pulmonary contusion is associated with higher mortality and ARDS compared with the absence of such findings. This suggests that the initial chest radiographs have prognostic significance in relation to pulmonary contusions due to blunt trauma.
