RESUMO
PURPOSE: Postinjury multiple organ failure (MOF) is the sequela to the disease of polytrauma. We aimed to describe the contemporary population-based epidemiology of MOF within a mature trauma system, to analyse the time taken for MOF to develop, and to evaluate the temporal patterns and contributions of the individual constituent organ failures. METHODS: Prospective observational study conducted across five Level-1 trauma centers in New South Wales, Australia. Trauma patients at-risk of MOF (Denver > 3 from 48 h post-admission), aged > 16 years, ISS > 15, and who stayed in ICU for ≥ 48 h were eligible for inclusion. RESULTS: From May 2018-February 2021, 600 at-risk polytrauma patients were prospectively enrolled (mean(SD)age = 49(21)years, males = 453/600(76%),median(IQR)ISS = 26(20,34)). MOF incidence was 136/600(23%) among at-risk patients, 142/6248(2%) among major trauma patients (ISS > 12 per Australian definition), and 0.8/100,000 in the general population. The mortality rate was 55/600(11%) in the overall study population, and 34/136(25%) in MOF patients. 82/136(60%) of MOF patients developed MOF on day-3. No patients developed MOF after day-13. Among MOF patients, 60/136(44%) had cardiac failures (mortality = 37%), 39/136(29%) had respiratory failures (mortality = 23%), 24/136(18%) had renal failures (mortality = 63%), and 12/136(9%) had hepatic failures (mortality = 50%). CONCLUSION: Although a rare syndrome in the general population, MOF occurred in 23% of the most severely injured polytrauma patients. When compared to previous risk-matched cohorts, MOF become more common, but not more lethal, despite a decade older cohort. The heart has superseded the lungs as the most common organ to fail. Cardiac and respiratory failures occurred earlier and were associated with lower mortality than renal and hepatic failures.
RESUMO
BACKGROUND: Handheld ultrasound devices present an opportunity for prehospital sonographic assessment of trauma, even in the hands of novice operators commonly found in military, maritime, or other austere environments. However, the reliability of such point-of-care ultrasound (POCUS) examinations by novices is rightly questioned. A common strategy being examined to mitigate this reliability gap is remote mentoring by an expert. OBJECTIVES: To assess the feasibility of utilizing POCUS in the hands of novice military or civilian emergency medicine service (EMS) providers, with and without the use of telementoring. To assess the mitigating or exacerbating effect telementoring may have on operator stress. METHODS: Thirty-seven inexperienced physicians and EMTs serving as first responders in military or civilian EMS were randomized to receive or not receive telementoring during three POCUS trials: live model, Simbionix trainer, and jugular phantom. Salivary cortisol was obtained before and after the trial. Heart rate variability monitoring was performed throughout the trial. RESULTS: There were no significant differences in clinical performance between the two groups. Iatrogenic complications of jugular venous catheterization were reduced by 26% in the telementored group (P < 0.001). Salivary cortisol levels dropped by 39% (P < 0.001) in the telementored group. Heart rate variability data also suggested mitigation of stress. CONCLUSIONS: Telementoring of POCUS tasks was not found to improve performance by novices, but findings suggest that it may mitigate caregiver stress.

BACKGROUND: The Prevent Alcohol and Risk Related Trauma in Youth (P.A.R.T.Y) program is an interactive injury prevention intervention, specifically designed for "at risk" youths aged 15 to 19 years. Emerging evidence has highlighted its positive impact on altering student attitudes towards risk-taking behaviour across several Australian and international settings. This study aims to describe the risk-taking behaviours of youths in South-Western and Greater Western Sydney, and assess the effectiveness of the Liverpool P.A.R.T.Y program to alter attitudes towards risk-taking. METHODS: From 2015 to 2020, schools and youth organisations across South-Western and Greater Western Sydney were invited to participate in the Liverpool Hospital P.A.R.T.Y program. Youths aged 15 to 19 years were selected to attend by their respective teachers based on eligibility criteria. Knowledge and attitudes towards risk-taking behaviours were measured using surveys across three time points (pre-program, immediately post-program, 3-to-6 months post-program). RESULTS: A total of 2544 participants from 50 schools and youth organisations attended the Liverpool Hospital P.A.R.T.Y program. There were 130 participants who did not record a response to a single question across all three time points and were omitted from analysis. Of the remaining 2414 participants, 49% were male, and 41% had access to a provisional driver's license or learner's permit. There were significant changes in knowledge and attitudes to risk-taking behaviours from pre-to immediately-post-program. A separate analysis across all three time points was conducted in response to a poor 3-to-6-month follow-up rate (25%). There was decay in improvements across all six questions, with the largest change seen in perceived likelihood of injury when engaging in physically risk-taking activities (52.2% to 36.9%, OR 0.44, 95% CI 0.33 - 0.60, p < 0.001). CONCLUSION: This study demonstrated significant changes in participant attitudes towards risk-taking behaviours and their consequences, immediately after participating in the Liverpool Hospital P.A.R.T.Y program. However, the poor response rates at later follow-up highlight the need for ongoing engagement of the South-Western and Greater Western Sydney youths, to ensure these improvements are sustained.

BACKGROUND: It is unknown how frequently damage control (DC) laparotomy is used across trauma centers in different countries. We conducted a cross-sectional survey of trauma centers in the United States, Canada, and Australasia to study variations in use of the procedure and predictors of more frequent use of DC laparotomy. METHODS: A self-administered, electronic, cross-sectional survey of trauma centers in the United States, Canada, and Australasia was conducted. The survey collected information about trauma center and program characteristics. It also asked how often the trauma program director estimated DC laparotomy was performed on injured patients at that center on average over the last year. Multivariable logistic regression was used to identify predictors of a higher reported frequency of use of DC laparotomy. RESULTS: Of the 366 potentially eligible trauma centers sent the survey, 199 (51.8%) trauma program directors or leaders responded [United States = 156 (78.4%), Canada = 26 (13.1%), and Australasia = 17 (8.5%)]. The reported frequency of use of DC laparotomy was highly variable across trauma centers. DC laparotomy was used more frequently in level-1 than level-2 or -3 trauma centers. Further, high-volume level-1 centers used DC laparotomy significantly more often than lower volume level-1 centers (p = 0.02). Nearly half (48.4%) of high-volume volume level-1 trauma centers reported using the procedure at least once weekly. Significant adjusted predictors of more frequent use of DC laparotomy included country of origin [odds ratio (OR) for the United States vs. Canada = 7.49; 95% confidence interval (CI) 1.39-40.27], level-1 verification status (OR = 6.02; 95% CI 2.01-18.06), and the assessment of a higher number of severely injured (Injury Severity Scale score > 15) patients (OR per-100 patients = 1.62; 95% CI 1.20-2.18) and patients with penetrating injuries (OR per-5% increase = 1.27; 95% CI 1.01-1.58) in the last year. CONCLUSIONS: The reported frequency of use of DC laparotomy was highly variable across trauma centers. Those centers that most need to evaluate the benefit-to-risk ratio of using DC laparotomy in different scenarios may include high-volume, level-1 trauma centers, particularly those that often manage penetrating injuries.

BACKGROUND: Given the increasing numbers of older patients presenting with trauma, and the potential influence of delirium on outcomes, we sought to investigate the proportion of such patients who were diagnosed with delirium during their stay-and patient factors associated therewith-and the potential associations between delirium and hospital length of stay (LOS). We hypothesized that delirium would be common, associated with certain patient characteristics, and associated with long hospital LOS (highest quartile). METHODS: We conducted a retrospective observational cohort study of all trauma patients aged ≥65 years presenting in September to October 2019, interrogating medical records and the institutional trauma database. The primary outcome measure was occurrence of delirium. RESULTS: Among 99 eligible patients, delirium was common, documented in 23% (23 of 99). On multivariable analysis, adjusting for age, frailty and history of dementia, frailty (OR 4.09, 95% CI 1.08 to 15.53, p=0.04) and dementia (OR 5.23, 95% CI 1.38 to 19.90, p=0.02) were independently associated with likelihood of delirium. Standardized assessment tools were underused, with only 34% (34 of 99) screened within 4 hours of arrival. On univariate logistic regression analysis, having an episode of delirium was associated with long LOS (highest quartile), OR of 5.29 (95% CI 1.92 to 14.56, p<0.001). In the final multivariable model, adjusting for any (non-delirium) in-hospital complication, delirium was independently associated with long LOS (≥16 days; OR 4.81, p=0.005). DISCUSSION: In this study, delirium was common. History of dementia and baseline frailty were associated with increased risk. Delirium was independently associated with long LOS. However, many patients did not undergo standardized screening at admission. Early identification and targeted management of older patients at risk of delirium may reduce incidence and improve care of this vulnerable cohort. These data are hypothesis generating, but support the need for initiatives which improve delirium care, acknowledging the complex interplay between frailty and other geriatric syndromes in the older trauma patients. LEVEL OF EVIDENCE: III.
RESUMO
OBJECTIVE: The primary objective of this study was to evaluate the utility, clinical impact, and work flow of a new trauma hybrid operating theater. SUMMARY BACKGROUND DATA: The potential utility and clinical benefit of hybrid operating theaters are increasingly postulated. Unfortunately, the clinical outcomes and efficiencies of these environments remain unclear. METHODS: All severely injured patients who were transferred to the hybrid suite for emergent intervention between 2013 and 2017 were compared to consecutive prehybrid patients. Standard statistical methodology was employed (P < 0.05â=âsignificant). RESULTS: One hundred sixty-nine patients with severe injuries (mean ISS = 23; hemodynamic instability = 70%; hospital/ICU stay = 12 d; mortality = 14%) were transferred urgently to the hybrid suite. Most were young (38 yrs) males (84%) with blunt injuries (51%). Combined hybrid trauma procedures occurred in 18% of cases (surgery (82%) and angiography (11%) alone). Procedures within the hybrid suite included: laparotomy (57%), extremity (14%), thoracotomy/sternotomy (12%), angioembolization of the spleen/pelvis/liver/other (9%), neck (9%), craniotomy (4%), and aortic endostenting (6%). Compared with historical controls, use of the hybrid suite resulted in shorter arrival to intervention and total procedure times (P < 0.05). A clear benefit for survival was evident (42% vs. 22%). CONCLUSIONS: Availability of a hybrid environment for severely injured patients reduces time to intervention, total procedural duration, blood product transfusion and salvages a small subset of patients who would not otherwise survive. The cost associated with a hybrid suite remains prohibitive for many centers.

BACKGROUND: We aimed to evaluate the evolution and implementation of the massive transfusion protocol (MTP) in an urban level 1 trauma centre. Most data on this topic comes from trauma centres with high exposure to life-threatening haemorrhage. This study examines the effect of the introduction of an MTP in an Australian level 1 trauma centre. METHODS: A retrospective study of prospectively collected data was performed over a 14-year period. Three groups of trauma patients, who received more than 10 units of packed red blood cells (PRBC), were compared: a pre-MTP group (2002-2006), an MTP-I group (2006-2010) and an MTP-II group (2010-2016) when the protocol was updated. Key outcomes were mortality, complications and number of blood products transfused. RESULTS: A total of 168 patients were included: 54 pre-MTP patients were compared to 47 MTP-I and 67 MTP-II patients. In the MTP-II group, fewer units of PRBC and platelets were administered within the first 24 h: 17 versus 14 (P = 0.01) and 12 versus 8 (P < 0.001), respectively. Less infections were noted in the MTP-I group: 51.9% versus 31.9% (P = 0.04). No significant differences were found regarding mortality, ventilator days, intensive care unit and total hospital lengths of stay. CONCLUSION: Introduction of an MTP-II in our level 1 civilian trauma centre significantly reduced the amount of PRBC and platelets used during damage control resuscitation. Introduction of the MTP did not directly impact survival or the incidence of complications. Nevertheless, this study reflects the complexity of real-life medical care in a level 1 civilian trauma centre.

Background:Tension pneumothorax is a frequent cause of potentially preventable death. Tube thoracostomy (TT) can obviate death but is invasive and fraught with complications even in experienced hands. We assessed the utility of a remote international virtual network (RIVN) of specialized mentors to remotely guide military medical technicians (medics) using wireless informatics.Methods:Medics were randomized to insert TT in training mannequins (TraumaMan; Abacus ALS, Meadowbrook, Australia) supervised by RIVN or not. The RIVN consisted of trauma surgeons in Canada and Australia and a senior medic in Ohio. Medics wore a helmet-mounted wireless camera with laser pointer to confirm anatomy and two-way voice communication using commercial software (Skype®). Performance was measured through objective task completion (pass/fail) regarding safety during the procedure, proper location, and secure anchoring of the tube, in addition to remote mentor opinion and subjective debrief.Results:Fourteen medics attempted TT, seven mentored and seven not. The RIVN was functional and surgeons on either side of the globe had real-time communication with the mentees. TT placement was considered safe, successful, and secure in 100% of mentored (n = 7) procedures, although two (29%) received corrective remote guidance. All (100%) of the unmentored attempted and adequately secured the TT and were safe. However, only 71% (n = 5) completed the task successfully (p = 0.46). Participating medics subjectively felt remote telementoring (RTM) increased self-confidence (strong agreement mean 5/5 ± 0); confidence to perform field TT (agreement (4/5 ± 1); and decreased anxiety (strong agreement 5/5 ± 1). Subjectively, the remote mentors felt in 100% of the mentored procedures that "yes" they were able to assist the medics (1.86 ± 0.38), and in 71% (n = 5) felt "yes" they made TT safer (2.29 ± 0.49).Conclusions:RTM descriptively increased the success of TT placement and allowed for real-time troubleshooting from thousands of kilometers with a redundant capability. RTM was subjectively associated with high levels of satisfaction and self-reported self-confidence. Continued controlled and critical evaluation and refinement of telemedical techniques should continue. Trial Registration: ID ISRCTN/77929274.

OBJECTIVES: To characterize and evaluate indications for use of damage control (DC) surgery in civilian trauma patients. BACKGROUND: Although DC surgery may improve survival in select, severely injured patients, the procedure is associated with significant morbidity, suggesting that it should be used only when appropriately indicated. METHODS: Two investigators used an abbreviated grounded theory method to synthesize indications for DC surgery reported in peer-reviewed articles between 1983 and 2014 into a reduced number of named, content-characteristic codes representing unique indications. An international panel of trauma surgery experts (n = 9) then rated the appropriateness (expected benefit-to-harm ratio) of the coded indications for use in surgical practice. RESULTS: The 1107 indications identified in the literature were synthesized into 123 unique pre- (n = 36) and intraoperative (n = 87) indications. The panel assessed 101 (82.1%) of these indications to be appropriate. The indications most commonly reported and assessed to be appropriate included pre- and intraoperative hypothermia (median temperature <34°C), acidosis (median pH <7.2), and/or coagulopathy. Others included 5 different injury patterns, inability to control bleeding by conventional methods, administration of a large volume of packed red blood cells (median >10 units), inability to close the abdominal wall without tension, development of abdominal compartment syndrome during attempted abdominal wall closure, and need to reassess extent of bowel viability. CONCLUSIONS: This study identified a comprehensive list of candidate indications for use of DC surgery. These indications provide a practical foundation to guide surgical practice while studies are conducted to evaluate their impact on patient care and outcomes.

The Abdominal Compartment Society (www.wsacs.org) previously created highly cited Consensus Definitions/Management Guidelines related to intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS). Implicit in this previous work, was a commitment to regularly reassess and update in relation to evolving research. Two years preceding the Fifth World Congress on Abdominal Compartment Syndrome, an International Guidelines committee began preparation. An oversight/steering committee formulated key clinical questions regarding IAH/ /ACS based on polling of the Executive to redundancy, structured according to the Patient, Intervention, Comparator, and Outcome (PICO) format. Scientific consultations were obtained from Methodological GRADE experts and a series of educational teleconferences were conducted to educate scientific review teams from among the wscacs. org membership. Each team conducted systematic or structured reviews to identify relevant studies and prepared evidence summaries and draft Grades of Recommendation Assessment, Development and Evaluation (GRADE) recommendations. The evidence and draft recommendations were presented and debated in person over four days. Updated consensus definitions and management statements were derived using a modified Delphi method. A writingcommittee subsequently compiled the results utilizing frequent Internet discussion and Delphi voting methods to compile a robust online Master Report and a concise peer-reviewed summarizing publication. A dedicated Paediatric Guidelines Subcommittee reviewed all recommendations and either accepted or revised them for appropriateness in children. Of the original 12 IAH/ACS definitions proposed in 2006, three (25%) were accepted unanimously, with four (33%) accepted by > 80%, and four (33%) accepted by > 50%, but required discussion to produce revised definitions. One (8%) was rejected by > 50%. In addition to previous 2006 definitions, the panel also defined the open abdomen, lateralization of the abdominal musculature, polycompartment syndrome, abdominal compliance, and suggested a refined open abdomen classification system. Recommendations were possible regarding intra-abdominal pressure (IAP) measurement, approach to sustained IAH, philosophy of protocolized IAP management and same-hospital-stay fascial closure, use of decompressive laparotomy, and negative pressure wound therapy. Consensus suggestions included use of non-invasive therapies for treating IAH/ACS, considering body position and IAP, damage control resuscitation, prophylactic open abdomen usage, and prudence in early biological mesh usage. No recommendations were made for the use of diuretics, albumin, renal replacement therapies, and utilizing abdominal perfusion pressure as a resuscitation-endpoint. Collaborating Methodological Guideline Development and Clinical Experts produced Consensus Definitions/Clinical Management statements encompassing the most contemporary evidence. Data summaries now exist for clinically relevant IAH/ACS questions, which will facilitate future scientific reanalysis.

BACKGROUND: The use of abbreviated or damage control (DC) interventions may improve outcomes in severely injured patients when appropriately indicated. We sought to determine which indications for DC interventions have been most commonly reported in the peer-reviewed literature to date and evaluate the opinions of experts regarding the appropriateness (expected benefit-to-harm ratio) of the reported indications for use in practice. METHODS: Two investigators used an abbreviated grounded theory method to synthesize indications for 16 different DC interventions reported in peer-reviewed articles between 1983 and 2014 into a reduced number of named, content-characteristic codes representing unique indications. For each indication code, an international panel of trauma surgery experts (n = 9) then rated the appropriateness of conducting the DC intervention of interest in an adult civilian trauma patient. RESULTS: The 424 indications identified in the literature were synthesized into 101 unique indications. The panel assessed 12 (70.6%) of the coded indications for the 7 different thoracic, 47 (78.3%) for the 7 different abdominal/pelvic, and 18 (75.0%) for the 2 different vascular interventions to be appropriate for use in practice. These included indications for rapid lung-sparing surgery (pneumonorrhaphy, pulmonary tractotomy, and pulmonary wedge resection) (n = 1); pulmonary tractotomy (n = 3); rapid, simultaneously stapled pneumonectomy (n = 1); therapeutic mediastinal and/or pleural space packing (n = 4); temporary thoracic closure (n = 3); therapeutic perihepatic packing (n = 28); staged pancreaticoduodenectomy (n = 2); temporary abdominal closure (n = 12); extraperitoneal pelvic packing (n = 5); balloon catheter tamponade (n = 6); and temporary intravascular shunting (n = 11). CONCLUSION: This study identified a list of candidate appropriate indications for use of 12 different DC interventions that were suggested by authors of peer-reviewed articles and assessed by a panel of independent experts to be appropriate. These indications may be used to focus future research and (in the interim) guide surgical practice while studies are conducted to evaluate their impact on patient outcomes.

BACKGROUND: Abdominal Compartment Syndrome (ACS) is an uncommon but deleterious complication after trauma laparotomy. Early recognition of patients at risk of developing ACS is crucial for their outcome. The aim of this study was to compare the characteristics of patients who developed high-grade intra-abdominal hypertension (IAH) (i.e., grade III or IV; intra-abdominal pressure, IAP >20 mm Hg) following an injury-related laparotomy versus those who did not (i.e., IAP ≤20 mm Hg). METHODS: A retrospective analysis of consecutive trauma patients admitted to a level 1 trauma centre in Australia between January 1, 1995 and January 31, 2010 was performed. A comparison was made between characteristics of patients who developed high-grade IAH following trauma laparotomy versus those who did not. RESULTS: A total of 567 patients (median age 31 years) were included in this study. Of these patients 10.2% (58/567) developed high-grade IAH of which 51.7% (30/58) developed ACS. Patients with high-grade IAH were older (p<0.001), had a higher Injury Severity Score (p<0.001), larger base deficit (p<0.001) and lower temperature at admission (p=0.011). In the first 24h of admission, patients with high-grade IAH received larger volumes of crystalloids (p<0.001), larger volumes of colloids (p<0.001) and more units of packed red blood cells (p<0.001). Following surgery prolonged prothrombin (p<0.001) and partial thromboplastin times (p<0.001) were seen. The patients with high-grade IAH suffered higher mortality rates (25.9% (15/58) vs. 12.2% (62/509); p=0.012). CONCLUSION: Of all patients who underwent a trauma laparotomy, 10.2% developed high-grade IAH, which increases the risk of mortality. Patients with acidosis, coagulopathy, and hypothermia were especially at risk. In these patients, the abdomen should be left open until adequate resuscitation has been achieved, allowing for definitive surgery. LEVEL OF EVIDENCE: This is a level III retrospective study.

AIM: The ideal strategy for prehospital intravenous fluid resuscitation in trauma remains unclear. Fluid resuscitation may reverse shock but aggravate bleeding by raising blood pressure and haemodilution. We examined the effect of prehospital i.v. fluid on the physiologic status and need for blood transfusion in hypotensive trauma patients after their arrival in the emergency department (ED). METHODS: Retrospective analysis of trauma patients (n=941) with field hypotension presenting to a level 1 trauma centre. Regression models were used to investigate associations between prehospital fluid volumes and shock index and blood transfusion respectively in the emergency department and mortality at 24h. RESULTS: A 1L increase of prehospital i.v. fluid was associated with a 7% decrease of shock index in the emergency department (p<0.001). Volumes of 0.5-1L and 1-2L were associated with reduced likelihood of shock as compared to volumes of 0-0.5L: OR 0.61 (p=0.03) and OR 0.54 (p=0.02), respectively. Volumes of 1-2L were also associated with an increased likelihood of receiving blood transfusion in ED: OR 3.27 (p<0.001). Patients who had received volumes of >2L have a much greater likelihood of receiving blood transfusion in ED: OR 9.92 (p<0.001). Mortality at 24h was not associated with prehospital i.v. fluids. CONCLUSION: In hypotensive trauma patients, prehospital i.v. fluids were associated with a reduction of likelihood of shock upon arrival in ED. However, volumes of >1L were associated with a markedly increased likelihood of receiving blood transfusion in ED. Therefore, decision making regarding prehospital i.v. fluid resuscitation is critical and may need to be tailored to the individual situation. Further research is needed to clarify whether a causal relationship exists between prehospital i.v. fluid volume and blood transfusion. Also, prospective trials on prehospital i.v. fluid resuscitation strategies in specific patient subgroups (e.g. traumatic brain injury and concomitant haemorrhage) are warranted.

OBJECTIVE: To investigate screening variables identifying patients at risk of developing intra-abdominal hypertension (IAH) after cardiac surgery. DESIGN AND SETTING: Prospective observational study in a tertiary general intensive care unit. PARTICIPANTS: One hundred and eight patients admitted to the ICU after cardiac surgery, with measurements of intraabdominal pressure (IAP). MAIN OUTCOME MEASURES: Routinely collected clinical, physiological and biochemical variables were analysed with at least twice-daily measurements of IAP during the postoperative stay in the ICU. Variables available within 24 hours of admission to the ICU were evaluated against the incidence of IAH using logistic regression analysis to develop a set of screening criteria to identify patients at risk. RESULTS: Fifty patients (46%) developed IAH during their stay in the ICU and were ventilated for longer, needed more vasopressors and stayed one more day in the ICU. Plasma albumin concentration, central venous pressure, minimal abdominal perfusion pressure, cardiopulmonary and aortic cross-clamp times and the presence of abdominal distension within the first 24 hours were associated with the occurrence of IAH. A logistic regression model using these variables correctly identified 85% of patients who developed IAH. CONCLUSIONS: A set of screening criteria routinely available within the first 24 hours of admission to the ICU after cardiac surgery could correctly identify most patients at risk of IAH.

AIMS: To Describe injury profile and costs of older person trauma in New South Wales; quantify variations with peer group costs; and identify predictors of higher costs. METHODS: Nine level 1 New South Wales trauma centres provided data on major traumas (aged ≥ 55 years) during 2008-2009 financial year. Trauma register and financial data of each institution were linked. Treatment costs were compared with peer group Australian Refined Diagnostic Related Groups costs, on which hospital funding is based. Variables examined through multivariate analyses. RESULTS: Six thousand two hundred and eighty-nine patients were admitted for trauma. Most common injury mechanism was falls (74.8%) then road trauma (14.9%). Median patient cost was $7044 (Q1-3: $3405-13 930) and total treatment costs $76 694 252. Treatment costs were $5 813 975 above peer group average. Intensive care unit admission, age, injury severity score, length of stay and traumatic brain injury were independent predictors of increased costs. CONCLUSION: Older person trauma attracts greater costs and length of stay. Cost increases with age and injury severity. Hospital financial information and trauma registry data provides accurate cost information that may inform future funding.

BACKGROUND: Modern trauma care relies heavily on nonoperative, emergent percutaneous procedures, particularly in patients with splenic, pelvic and hepatic injuries. Unfortunately, specific quality measures (e.g., arrival to angiography times) have not been widely discussed. Our objective was to evaluate the time interval from arrival to initiation of emergent percutaneous procedures in severely injured patients. METHODS: All severely injured trauma patients (injury severity score [ISS] > 12) presenting to a level 1 trauma centre (2007-2010) were analyzed with standard statistical methodology. RESULTS: Among 60 severely injured patients (mean ISS 31, hypotension 18%, mortality 12%), the median time interval to the initiation of an angiographic procedure was 270 minutes. Of the procedures performed, 85% were therapeutic embolizations and 15% were diagnostic procedures. Splenic (median time 243 min, range 32-801 min) and pelvic (median time 278 min, range 153-466 min) embolizations accounted for 43% and 25% of procedures, respectively. The median embolization procedure duration for the spleen was 28 (range 15-153) minutes compared with 59 (range 34-171) minutes for the pelvis. Nearly 22% of patients required both an emergent percutaneous and subsequent operative procedure. Percutaneous therapy typically preceded open operative explorations. CONCLUSION: The time interval from arrival at the trauma centre to emergent percutaneous procedures varied widely. Improved processes emphasizing patient transition from the trauma bay to the angiography suite are essential. Discussion regarding the appropriate time to angiography is needed so this marker can be used as a quality outcome measure for all level 1 trauma centres.
CONTEXTE: De nos jours, en traumatologie, les soins reposent largement sur des interventions non chirurgicales percutanées d'extrême urgence, particulièrement chez les patients blessés à la rate, au bassin et au foie. Malheureusement, les indices de qualité spécifiques (p. ex., temps écoulé entre l'arrivée et l'angiographie) n'ont pas fait l'objet de discussions approfondies. Notre objectif était de mesurer le temps écoulé entre l'arrivée et l'instauration des interventions percutanées d'extrême urgence chez les grands blessés. MÉTHODES: Tous les grands polytraumatisés (indice de gravité des blessures [IGB] > 12) amenés dans un centre de traumatologie de niveau 1 (20072010) ont fait l'objet d'une analyse au moyen d'une méthodologie statistique standard. RÉSULTATS: Pour 60 patients gravement blessés (IGB moyen 31, hypotension 18 %, mortalité 12%), le temps écoulé avant l'instauration d'une intervention angio gra phique a été de 270 minutes. Parmi les interventions effectuées, 85% ont été des embolisations thérapeutiques et 15% des interventions diagnostiques. Les embolisations spléniques (temps écoulé médian 243 minutes, intervalle 32801 minutes) et pelviennes (temps écoulé médian 278 minutes, intervalle 153466 minutes) ont représenté 43% et 25% des interventions, respectivement. La durée médiane de l'intervention d'embolisation dans le cas de la rate a été de 28 (intervalle 15153) minutes, contre 59 (intervalle 34171) minutes pour les blessures touchant le bassin. Près de 22 % des patients ont eu besoin d'une intervention percutanée d'extrême urgence et d'une intervention chirurgicale par la suite. Les explorations chirurgicales ouvertes ont généralement été précédées d'un traitement percutané. CONCLUSION: Le temps écoulé entre l'arrivée au centre de traumatologie et les interventions percutanées d'extrême urgence varie beaucoup. Il faut, sans contredit, améliorer les processus en soulignant l'importance du transfert des patients de la salle de traumatologie à la salle d'angiographie et poursuivre la discussion sur le temps écoulé avant l'angiographie pour que ce marqueur puisse servir comme paramètre de mesure de la qualité dans tous les centres de traumatologie de niveau 1.

PURPOSE OF REVIEW: In recent years, combined interventional radiology and operative suites have been proposed and are now becoming operational in select trauma centres. Given the infancy of this technology, this review aims to review the rationale, benefits and challenges of hybrid suites in the management of seriously injured patients. RECENT FINDINGS: No specific studies exist that investigate outcomes within hybrid trauma suites. Endovascular and interventional radiology techniques have been successfully employed in thoracic, abdominal, pelvic and extremity trauma. Although the association between delayed haemorrhage control and poorer patient outcomes is intuitive, most supporting scientific data are outdated. The hybrid suite model offers the potential to expedite haemorrhage control through synergistic operative, interventional radiology and resuscitative platforms. Maximizing the utility of these suites requires trained multidisciplinary teams, ergonomic and workplace considerations, as well as a fundamental paradigm shift of trauma care. This often translates into a more damage-control orientated philosophy. SUMMARY: Hybrid suites offer tremendous potential to expedite haemorrhage control in trauma patients. Outcome evaluations from trauma units that currently have operational hybrid suites are required to establish clearer guidelines and criteria for patient management.
