Abstract: Introduction: To evaluate the validity of the 12-item Short Form Health Survey (SF-12), Sickness Impact Profile (SIP) and the Short Musculoskeletal Functional Assessment Questionnaire (SMFA) for use in an orthopaedic trauma population. Materials and methods: A prospective validation trial was completed at a Level 1 adult trauma centre in Melbourne, Australia. One hundred and fifty four patients with orthopaedic trauma managed or followed-up by an orthopaedic unit were prospectively recruited. Patients with pathological fractures related to metastatic disease and/or an isolated orthopaedic injury, a documented history of mental illness or dementia or those for whom follow-up was likely to be difficult were excluded. The SF-12, SIP and SMFA were administered by a trained interviewer at one and six months. Each questionnaire was scored for the physical and mental components and then compared for content and construct validity at each time point. Results: Complete data were collected for 134 patients at one and six months. The one and six month component scores correlated strongly between the SF-12 physical, SIP physical (r =0.513–0.669) and SMFA dysfunction (r =0.529–0.778); the SF-12 mental, SIP mental (r =0.643–0.719) and SMFA bother (r =0.564–0.602) components. The strength of association was greater for the six month time point compared to the one month measure. The SF-12 demonstrated no ceiling or floor effects, and provided a lower time burden on participants and researchers when compared to the SIP and SMFA. Conclusions: For large population-based surveillance research into orthopaedic injury the SF-12 provides a valid and versatile tool. [Copyright &y& Elsevier]

Summary: Precise prehospital trauma triage criteria are critical for ensuring patients with severe injuries are transported to trauma centres. Most prehospital trauma triage criteria adopt a combination of physiological, anatomic and mechanism of injury components, but this approach still fails to identify a number of patients with severe injuries and often burdens trauma centres with patients suffering minor injuries. Paramedic judgement has been identified as an alternative method for the triage of trauma patients. This study critically reviewed the literature regarding the ability of paramedics to predict injury severity, and found there is no clear evidence supporting paramedic judgement as an accurate triage method. However, the studies were limited due to significant data losses, variable definitions of major trauma, differences across EMS and trauma care systems, variable paramedic experience levels and incomparable methods of data collection. The role of paramedic judgement in identifying patients with severe blunt anatomic injuries requires further investigation. [Copyright &y& Elsevier]

Objective: To i) quantify the agreement between comorbidities documented within medical records and an orthopaedic trauma dataset; and ii) compare agreement between these sources before and after the introduction of new comorbidity coding rules in Australian hospitals.Study Design and Setting: A random sample of adult (≥ 16 years) orthopaedic trauma patients (n = 400) were extracted from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Diagnoses of obesity, arthritis, diabetes and cardiac conditions documented within patients' medical records were compared to ICD-10-AM comorbidity codes (provided by hospitals) for the same admission. Agreement was calculated (Cohen's kappa) before and after the introduction of new coding rules.Results: All comorbidities had the same or higher prevalence in medical record data compared to coded data. Kappa values ranged from <0.001 (poor agreement) for coronary artery disease to 0.94 (excellent agreement) for type 2 diabetes. There was improvement in agreement between sources for most conditions following the introduction of new coding rules.Conclusion: There has been improvement in the coding of certain comorbidities since the introduction of new coding rules, suggesting that, since 2015, administrative data has improved capacity to capture patients' comorbidity profiles. Consideration must be taken when using the ICD-10-AM data due to its limitations. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to assess changes in patient activities and interactions observed in response to a new trauma ward at a level 1 trauma centre, and subsequently, a new allied health staffing model. Design: Explorative case study using behavioural mapping. Setting: Level 1 trauma centre in Melbourne, Australia. Participants: Hospitalised trauma patients. Main measures: Behavioural mapping of patients' activities and interactions was conducted by two observers over three 4-day observation phases: (i) at baseline, (ii) on the new ward and (iii) with the new staffing model. Changes in activities and interactions were assessed via negative binomial regression models and reported as incident rate ratios. Results: In total, 1264 patient observations were recorded over an 18-month period. After moving to the new ward, patients were observed performing activities of daily living at a 2.1-fold higher rate than at baseline (95% confidence interval: 1.18, 3.81) but walking/standing/climbing stairs 54% less (95% confidence interval: 0.22, 0.94). Subsequent to the new staffing model, patients were observed in the gym at a 4.1-fold higher rate (95% confidence interval: 1.60, 10.32) and interacting with allied health professionals at a 9.1-fold higher rate (95% confidence interval: 4.88, 16.98), than at baseline. After COVID-19 restrictions were introduced, patients were observed lying down 22% more (95% confidence interval: 1.04, 1.43), with 73% fewer visitor interactions (95% confidence interval: 0.17, 0.43). Conclusions: Greater engagement in physical and social activities was observed following the implementation of the new allied health staffing model at a level 1 trauma centre. Whether these changes translate to improved trauma outcomes is important to investigate. [ABSTRACT FROM AUTHOR]

Background: Although orthopaedic trauma results in significant disability and substantial financial cost, there is a paucity of large cohort studies that collectively describe the functional outcomes of a variety of these injuries. The current study aimed to investigate the outcomes of patients admitted with a range of orthopaedic injuries to adult Level 1 trauma centres. Methods: Patients were recruited from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR), which included all patients with orthopaedic trauma admitted to the two adult Level 1 trauma centres in Victoria (Australia). Patients were categorised into three groups; isolated orthopaedic injuries, multiple orthopaedic injuries and orthopaedic and other injuries. Demographic and injury data were collected from the medical record and hospital/trauma databases, and functional outcome instruments were given at 6 months post-injury. Results: Of the 1303 patients recruited for VOTOR over a 12-month period, 1181 patients were eligible for the study and a response rate of 75.6% was obtained at 6 months post-injury. Patients reported ongoing pain (moderate-severe: 37.2%), disability (79.5%) and inability to return to work (35.2%). Poorer outcomes were evident in patients with orthopaedic and other injuries than those with single or multiple orthopaedic injuries alone. Conclusion: A large percentage of patients have ongoing pain and disability and a reduced capacity to return to work 6 months after orthopaedic trauma. Further research into the long-term outcomes of patients with orthopaedic injuries is required to identify patient subgroups and specific injuries and procedures that result in high morbidity.

Trauma registries, like disease registries, provide an important analysis tool to assess the management of patient care. Trauma registries are well established and relatively common in the USA and have been used to change legislation, promote trauma prevention and to evaluate trauma system effectiveness. In Australia, the first truly statewide trauma registry was established in Victoria in 2001 with an estimated capture of 1700 major trauma cases annually. The Victorian State Trauma Registry, managed by the Victorian State Trauma Outcomes Registry and Monitoring (VSTORM) group, was established in response to a ministerial review of trauma and emergency services undertaken in 1997 to advise the Victorian Government on a best practice model of trauma service provision that was responsive to the particular needs of critically ill trauma patients. This taskforce recommended the establishment of a new system of care for major trauma patients in Victoria and a statewide trauma registry to monitor this new system. The development of the Victorian state trauma registry has shown that there are certain issues that must be resolved for successful implementation of any system-wide registry. This paper describes the issues faced by VSTORM in developing, implementing and maintaining a statewide trauma registry. [ABSTRACT FROM AUTHOR]

Objectives: To develop a hospital indicator of resource use for injury admissions.Methods: We focused on resource use for acute injury care and therefore adopted a hospital perspective. We included patients ≥16 years old with an Injury Severity Score >9 admitted to any of the 57 trauma centers of an inclusive Canadian trauma system from 2014 to 2018. We extracted data from the trauma registry and hospital financial reports and estimated resource use with activity-based costing. We developed risk-adjustment models by trauma center designation level (I/II and III/IV) for the whole sample, traumatic brain injuries, thoraco-abdominal injuries, orthopedic injuries, and patients ≥65 years old. Candidate variables were selected using bootstrap resampling. We performed benchmarking by comparing the adjusted mean cost in each center, obtained using shrinkage estimates, to the provincial mean.Results: We included 38 713 patients. The models explained between 12% and 36% (optimism-corrected r2) of the variation in resource use. In the whole sample and in all subgroups, we identified centers with higher- or lower-than-expected resource use across level I/II and III/IV centers.Conclusions: We propose an algorithm to produce the indicator using data routinely collected in trauma registries to prompt targeted exploration of potential areas for improvement in resource use for injury admissions. The r2 of our models suggest that between 64% and 88% of the variation in resource use for injury care is dictated by factors other than patient baseline risk. [ABSTRACT FROM AUTHOR]

Background Injuries represent one of the leading causes of preventable morbidity and mortality. For countries with ageing populations, admissions of injured older patients are increasing exponentially. Yet, we know little about hospital resource use for injured older patients. Our primary objective was to evaluate inter-hospital variation in the risk-adjusted resource use for injured older patients. Secondary objectives were to identify the determinants of resource use and evaluate its association with clinical outcomes. Methods We conducted a multicenter retrospective cohort study of injured older patients (≥65 years) admitted to any trauma centres in the province of Quebec (2013–2016, N  = 33,184). Resource use was estimated using activity-based costing and modelled with multilevel linear models. We conducted separate subgroup analyses for patients with trauma and fragility fractures. Results Risk-adjusted resource use varied significantly across trauma centres, more for older patients with fragility fractures (intra-class correlation coefficients [ICC] = 0.093, 95% CI [0.079, 0.102]) than with trauma (ICC = 0.047, 95% CI = 0.035–0.051). Risk-adjusted resource use increased with age, and the number of comorbidities, and varied with discharge destination (P  < 0.001). Higher hospital resource use was associated with higher incidence of complications for trauma (Pearson correlation coefficient r  = 0.5, 95% CI = 0.3–0.7) and fragility fractures (r  = 0.5, 95% CI = 0.3–0.7) and with higher mortality for fragility fractures (r  = 0.4, 95% CI = 0.2–0.6). Conclusions We observed significant inter-hospital variations in resource use for injured older patients. Hospitals with higher resource use did not have better clinical outcomes. Hospital resource use may not always positively impact patient care and outcomes. Future studies should evaluate mechanisms, by which hospital resource use impacts care. [ABSTRACT FROM AUTHOR]

Background: Variations in adjusted costs have been observed among trauma centres in the United States but patient outcomes were not better in centres with higher costs. Attempts to improve injury care efficiency are hampered by insufficient patient-level information on resource use and on the drivers of resource use intensity.Objectives: To estimate patient-level resource use for injury admissions, identify determinants of resource use intensity, and evaluate inter-hospital variations in resource use.Methods: We conducted a retrospective cohort study including ≥16-year-olds admitted to adult trauma centres in a mature, inclusive Canadian trauma system between 2014 and 2016. We extracted data from the trauma registry and hospital financial reports. We estimated resource use with activity-based costs, identified determinants of resource use intensity using a multilevel linear model and assessed the relative importance of each determinant with Cohen's f2. We evaluated inter-provider variations with intraclass correlation coefficients (ICC) and 95% confidence intervals.Results: We included 32,411 patients. Median costs per admission were $4857 (Quartiles 1 and 3 2961-8448). The most important contributors to total resource use were the medical ward (57%), followed by the operating room (OR; 23%) and the intensive care unit (13%). The strongest determinant of resource use intensity was discharge destination (Cohen's f2 = 7%). The most resource intense patient group was spinal cord injuries with $11,193 (7115-17,606) per admission. While resource use increased with increasing age for the medical ward, it decreased with increasing age for the OR. Resource use was 18% higher in level I centres compared to level IV centres and we observed significant variations in resource use across centres (ICC = 5% [4-6]), particularly for the OR (28% [20-40]).Conclusions: Resource use for acute injury care in Quebec is not solely due to the clinical status of patients. We identified determinants of resource use that can be used to establish evidence-based resource allocations and improve injury care efficiency. The method we developed for estimating patient-level, in-hospital resource use for injury admissions and identifying related determinants could be reproduced using local trauma registry data and our unit costs or unit costs specific to each setting.

Background: Self-harm and intentional injuries represent a significant public health concern. People who survive serious injury from self-harm can experience poor outcomes that negatively impact on their daily life. The aim of this study was to investigate a cohort of major trauma patients hospitalised for self-harm in Victoria, and to identify risk factors for longer term mortality, functional recovery and return to work.Method: 482 adult major trauma patients who were injured due to self-harm and survived to hospital discharge, and were captured by the population-based Victorian State Trauma Registry (VSTR), were included. For those with a date of injury from January 1, 2007 to December 31, 2013, demographics and injury event data, Glasgow Outcome Scale Extended (GOS-E) and return to work (RTW) outcomes at 6, 12 and 24 months post-injury were extracted from the registry. Post-discharge mortality was identified through the Victorian Registry of Births, Deaths and Marriages (BDM). Multivariable logistic regression was used to determine predictors of the GOS-E and RTW and survival analysis was used to identify predictors of mortality.Results: A total of 37 (7.7%) deaths occurred post-discharge. There were no clear predictors of all-cause mortality. Overall, 36% of patients reported making a good recovery at 24 months. Older age (p=0.01), transport-related methods of self-harm (p=0.02), higher Injury Severity Score (p<0.001) and having a Charlson Comorbidity Index weighting of one or more (p=0.02) were predictive of poorer functional recovery. Of patients who were working or studying prior to injury, 54% reported returning to work by 24 months post-injury. Higher Injury Severity Score was an important predictor of not returning to work (p=0.002).Conclusion: The vast majority of major trauma patients who self-harmed and survived to hospital discharge were alive at two years post-injury, yet only half of this cohort returned to work and just over a third of patients experienced a good recovery.

Introduction: Trampoline-related injuries in adults are uncommon. Participation in trampolining is increasing following its admission as a sport in the Olympics and the opening of local recreational trampoline centres. The aim of this study was to assess the number and outcomes of adult trampoline-related orthopaedic injuries presenting to four trauma hospitals in Victoria.Methods: A cohort study was performed for the period 2007-2013. Adult patients registered by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) who had sustained a trampolining related injury were included in this study. Descriptive analyses were used to describe the patient population, the injuries sustained and their in-hospital and 6-month outcomes.Results: There was an increase in trampolining injuries from 2007 (n=3) to 2012 (n=14) and 2013 (n=18). Overall, fifty patients with a median age of 25 (range 16-66) were identified. Thirty-five patients (70%) had lower limb injuries, 20 patients (40%) had spinal injuries and one patient had an upper limb injury. Thirty-nine patients (78%) required surgery. Fractures of the tibia (n=13), ankle fractures (n=12) and cervical spine injuries (n=7) were the most common injuries; all of which required surgery. Complications included death, spinal cord injuries, compartment syndrome and open fractures. At 6 months post injury, more than half (52%) of the patients had not achieved a good recovery, 32% had some form of persistent disability, 14% did not get back to work and overall physical health for the cohort was well below population norms for the SF-12.Conclusion: Adult trampoline-related injuries have increased in the last few years in this cohort identified through VOTOR. Lower limb and spinal injuries are most prevalent. Public awareness and education are important to reduce the risk for people participating in this activity. [ABSTRACT FROM AUTHOR]
