Impact of a physician - critical care practitioner pre-hospital service in Wales on trauma survival: a retrospective analysis of linked registry data.

The Emergency Medical Retrieval and Transfer Service for Wales launched in 2015. This service delivers senior pre-hospital doctors and advanced critical care practitioners to the scene of time-critical life- and limb-threatening incidents to provide advanced decision-making and pre-hospital clinical care. The impact of the service on 30-day mortality was evaluated retrospectively using a data linkage system. The study included patients who sustained moderate-to-severe blunt traumatic injuries (injury severity score ≥ 9) between 27 April 2015 and 30 November 2018. The association between pre-hospital management by the Emergency Medical Retrieval and Transfer Service and 30-day mortality was assessed using multivariable logistic regression. In total, data from 4035 patients were analysed, of which 412 (10%) were treated by the Emergency Medical Retrieval and Transfer Service. A greater proportion of patients treated by the Emergency Medical Retrieval and Transfer Service had an injury severity score ≥ 16 and Glasgow coma scale ≤ 12 (288 (70%) vs. 1435 (40%) and 126 (31%) vs. 325 (9%), respectively). The unadjusted 30-day mortality rate was 11.7% for patients managed by the Emergency Medical Retrieval and Transfer Service compared with 9.6% for patients managed by standard pre-hospital care services. However, after adjustment for differences in case-mix, the 30-day mortality rate for patients treated by the Emergency Medical Retrieval and Transfer Service was 37% lower (adjusted odds ratio 0.63 (95%CI 0.41-0.97); p = 0.037). The introduction of an emergency medical retrieval service was associated with a reduction in 30-day mortality for patients with blunt traumatic injury.

The Funding, Administrative, and Policy Influences on the Evaluation of Primary Prevention Programs in Australia.

Evaluation of primary prevention and health promotion programs contributes necessary information to the evidence base for prevention programs. There is increasing demand for high-quality evaluation of program impact and effectiveness for use in public health decision making. Despite the demand for evidence and known benefits, evaluation of prevention programs can be challenging and organizations face barriers to conducting rigorous evaluation. Evaluation capacity building efforts are gaining attention in the prevention field; however, there is limited knowledge about how components of the health promotion and primary prevention system (e.g., funding, administrative arrangements, and the policy environment) may facilitate or hinder this work. We sought to identify the important influences on evaluation practice within the Australian primary prevention and health promotion system. We conducted in-depth semi-structured interviews with experienced practitioners and managers (n = 40) from government and non-government organizations, and used thematic analysis to identify the main factors that impact on prevention program evaluation. Firstly, accountability and reporting requirements impacted on evaluation, especially if expectations were poorly aligned between the funding body and prevention organization. Secondly, the funding and political context was found to directly and indirectly affect the resources available and evaluation approach. Finally, it was found that participants made use of various strategies to modify the prevention system for more favorable conditions for evaluation. We highlight the opportunities to address barriers to evaluation in the prevention system, and argue that through targeted investment, there is potential for widespread gain through improved evaluation capacity.

Revised Functional Capacity Index as a predictor of outcome following injury.

BACKGROUND: Assessment of functional outcomes in survivors of severe injury is an identified priority for trauma systems. The predictive Functional Capacity Index (pFCI) within the 2008 Abbreviated Injury Scale dictionary (pFCI08) offers a widely available tool for predicting functional outcomes without requiring long-term follow-up. This study aimed to assess the 12-month functional outcome predictions of pFCI08 in a major trauma population, and to test the assumptions made by its developers to ensure population homogeneity. METHODS: Patients with major trauma from Victoria, Australia, were followed up using routine telephone interviews. Assessment of survivors 12 months after injury included the Glasgow Outcome Scale - Extended (GOS-E). κ scores were used to measure agreement between pFCI08 and assessed GOS-E scores. RESULTS: Of 20 098 patients with severe injury, 12 417 had both pFCI08 and GOS-E scoring available at 12 months. The quadratic weighted κ score across this population was 0·170; this increased to 0·244 in the subgroup of 1939 patients who met all pFCI assumptions. However, expanding the age range used in this group did not significantly affect κ scores until patients over the age of 70 years were included. DISCUSSION: The pFCI08 has only a slight agreement with outcomes following major trauma. However, the age limits in the pFCI development assumptions are unnecessarily restrictive. The pFCI08 may be able to contribute to future systems predicting functional outcomes following severe injury, but is likely to explain only a small proportion of the variability in patient outcomes.

Injury surveillance in community sport: Can we obtain valid data from sports trainers?

A lack of available injury data on community sports participants has hampered the development of informed preventive strategies for the broad-base of sports participation. In community sports settings, sports trainers or first-aiders are well-placed to carry out injury surveillance, but few studies have evaluated their ability to do so. The aim of this study was to investigate the reporting rate and completeness of sports trainers' injury records and agreement between sports trainers' and players' reports of injury in community Australian football. Throughout the football season, one sports trainer from each of four clubs recorded players' injuries. To validate these data, we collected self-reported injury data from players via short message service (SMS). In total, 210 discrete injuries were recorded for 139 players, 21% by sports trainers only, 59% by players via SMS only, and 21% by both. Completeness of injury records ranged from 95% to 100%. Agreement between sports trainers and players ranged from K = 0.32 (95% confidence interval: 0.27, 0.37) for date of return to football to K = 1.00 for activity when injured. Injury data collected by sports trainers may be of adequate quality for providing an understanding of the profile of injuries. However, data are likely to underestimate injury rates and should be interpreted with caution.

Triaging the right patient to the right place in the shortest time.

Trauma systems have been successful in saving lives and preventing disability. Making sure that the right patient gets the right treatment in the shortest possible time is integral to this success. Most trauma systems have not fully developed trauma triage to optimize outcomes. For trauma triage to be effective, there must be a well-developed pre-hospital system with an efficient dispatch system and adequately resourced ambulance system. Hospitals must have clear designations of the level of service provided and agreed protocols for reception of patients. The response within the hospital must be targeted to ensure the sickest patients get an immediate response. To enable the most appropriate response to trauma patients across the system, a well-developed monitoring programme must be in place to ensure constant refinement of the clinical response. This article gives a brief overview of the current approach to triaging trauma from time of dispatch to definitive treatment.

Indicators of the quality of trauma care and the performance of trauma systems.

BACKGROUND: Valid and reliable measures of trauma system performance are needed to guide improvement activities, benchmarking and public reporting, future investment and research. Traditional measures of in-hospital mortality fail to take into account prehospital and posthospital care, recovery after discharge, and the nature and costs of long-term disability. METHODS: Drawing on recent systematic reviews, an overview was conducted of existing and emerging trauma care performance indicators. Changes in the nature and purpose of indicators were assessed. RESULTS: Among a large number of existing, mostly locally developed performance indicators, only peer review of deaths has evidence of validity or reliability. The usefulness of the traditional performance measure of in-hospital mortality has been challenged. There is an emerging shift in focus from mortality to non-mortality outcomes, from hospital-based to long-term community-based outcome assessment, and from single measures of trauma centre performance to measures better suited to monitoring the performance of systems of care spanning the entire patient journey. As a result, a new generation of indicators is emerging that are both feasible and potentially more useful for commissioners and payers of population-based services. CONCLUSION: A global endeavour is now under way to agree on a set of standardized performance indicators that are meaningful to patients, carers, clinicians, managers and service funders, are likely to contribute to desired outcomes, and are valid, reliable and have a strong evidence base.

Predictors of death and new disability after critical illness: a multicentre prospective cohort study.

PURPOSE: This study aimed to determine the prevalence and predictors of death or new disability following critical illness. METHODS: Prospective, multicentre cohort study conducted in six metropolitan intensive care units (ICU). Participants were adults admitted to the ICU who received more than 24 h of mechanical ventilation. The primary outcome was death or new disability at 6 months, with new disability defined by a 10% increase in the WHODAS 2.0. RESULTS: Of 628 patients with the primary outcome available (median age of 62 [49-71] years, 379 [61.0%] had a medical admission and 370 (58.9%) died or developed new disability by 6 months. Independent predictors of death or new disability included age [OR 1.02 (1.01-1.03), P = 0.001], higher severity of illness (APACHE III) [OR 1.02 (1.01-1.03), P < 0.001] and admission diagnosis. Compared to patients with a surgical admission diagnosis, patients with a cardiac arrest [OR (95% CI) 4.06 (1.89-8.68), P < 0.001], sepsis [OR (95% CI) 2.43 (1.32-4.47), P = 0.004], or trauma [OR (95% CI) 6.24 (3.07-12.71), P < 0.001] diagnosis had higher odds of death or new disability, while patients with a lung transplant [OR (95% CI) 0.21 (0.07-0.58), P = 0.003] diagnosis had lower odds. A model including these three variables had good calibration (Brier score 0.20) and acceptable discriminative power with an area under the receiver operating characteristic curve of 0.76 (95% CI 0.72-0.80). CONCLUSION: Less than half of all patients mechanically ventilated for more than 24 h were alive and free of new disability at 6 months after admission to ICU. A model including age, illness severity and admission diagnosis has acceptable discriminative ability to predict death or new disability at 6 months.

The association between hip and groin injuries in the elite junior football years and injuries sustained during elite senior competition.

OBJECTIVE: To establish the relationship between the history of hip and groin injuries in elite junior football players prior to elite club recruitment and the incidence of hip and groin injuries during their elite career. DESIGN: Retrospective cohort study. SETTING: Analysis of existing data. PARTICIPANTS: 500 Australian Football League (AFL) players drafted from 1999 to 2006 with complete draft medical assessment data. ASSESSMENT OF RISK FACTORS: Previous history of hip/groin injury, anthropometric and demographic information. MAIN OUTCOME MEASUREMENT: The number of hip/groin injuries resulting in > or =1 missed AFL game. RESULTS: Data for 500 players were available for analysis. 86 (17%) players reported a hip/groin injury in their junior football years. 159 (32%) players sustained a hip/groin injury in the AFL. Players who reported a previous hip or groin injury at the draft medical assessment demonstrated a rate of hip/groin injury in the AFL >6 times higher (IRR 6.24, 95% CI 4.43 to 8.77) than players without a pre-AFL hip or groin injury history. CONCLUSIONS: This study demonstrated that a hip or groin injury sustained during junior football years is a significant predictor of missed game time at the elite level due to hip/groin injury. The elite junior football period should be targeted for research to investigate and identify modifiable risk factors for the development of hip/groin injuries.

Outcomes of midfoot and hindfoot fractures in multitrauma patients.

INTRODUCTION: Multitrauma patients suffering hindfoot fractures, including calcaneal and talar fractures, often result in poor outcomes. However, less is known about the outcomes following midfoot fracture in the mutitrauma population. This study aims to describe the epidemiology of midfoot fractures in multitrauma patients and to compare the outcomes of midfoot and hindfoot fractures in this population. METHODS: Data about multitrauma patients (Injury Severity Score >12) sustaining a unilateral midfoot or hindfoot fracture were obtained from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) and from retrospective review of medical records at a major trauma centre. Further outcome data were obtained via a survey using the American Academy of Orthopedic Surgeons Foot and Ankle Score (AAOS FAS) and the 12-item Short Form Health Survey (SF-12). RESULTS: 122 multitrauma patients were included; 81 with hindfoot fractures and 41 with midfoot fractures. The median ISS (IQR) was 22 (17-29) and 27 (17-24) for the hindfoot and midfoot groups, respectively (p = 0.23). Hindfoot and midfoot fractures were commonly associated with intracranial injuries (80.3%), spine injuries (60.7%), ipsilateral lower extremity injuries (24.6%) and pelvic injuries (16.4%). The mean (SD) time to follow up was 4.5 (±2.7) years. There were no differences in mean SF-12 physical (37.97 vs 35.22, p = 0.33) or mental (46.90 vs 46.67, p = 0.94) component summary scores between the groups. There were no differences in mean AAOS FAS standard scores (69.3 vs 69.1, p = 0.97) or shoe comfort scores (median 40 vs 40 p = 0.18) between the groups. CONCLUSION: Functional outcomes in multitrauma patients with midfoot or hindfoot fractures were comparable. These findings suggest that midfoot fractures should be treated with the same degree of due diligence as hindfoot fractures in the multitrauma patient.

Major trauma in older persons.

BACKGROUND: Globally, populations are ageing, creating challenges for trauma system design. Despite this, little is known about causes of injury and long-term outcomes in older injured patients. This study aims to describe temporal trends in the incidence, causes and functional outcomes of major trauma in older adults. METHODS: The population-based Victorian State Trauma Registry was used to identify patients with major trauma aged 65 years and older with a date of injury between 1 January 2007 and 31 December 2016. Temporal trends in population-based incidence rates were evaluated. Functional outcome was measured using the Glasgow Outcome Scale - Extended. RESULTS: There were 9250 older adults with major trauma during the study period. Low falls were the most common mechanism of injury (62·5 per cent), followed by transport-related events (22·2 per cent) and high falls (9·5 per cent). The number of patients with major trauma aged 65 years and older more than doubled from 2007 to 2016, and the incidence increased by 4·3 per cent per year (incidence rate ratio 1·043, 95 per cent c.i. 1·035 to 1·050; P < 0·001). At 12 months after injury, 41·8 per cent of older adults with major trauma had died, and 52·2 per cent of those who survived to hospital discharge were not living independently. CONCLUSIONS: The number and proportion of older adults with major trauma are increasing rapidly and this will impact on trauma system design. Given the poor long-term outcomes, there needs to be greater emphasis on ensuring that appropriate interventions are targeted to the right patients and enhanced efforts in primary prevention.

Does the disabilities of the arm, shoulder and hand (DASH) scoring system only measure disability due to injuries to the upper limb?

Although the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was designed, and has been validated, as a measure of disability in patients with disorders of the upper limb, the influence of those of the lower limb on disability as measured by the DASH score has not been assessed. The aim of this study was to investigate whether it exclusively measures disability associated with injuries to the upper limb. The Short Musculoskeletal Functional Assessment, a general musculoskeletal assessment instrument, was also completed by participants. Disability was compared in 206 participants, 84 with an injury to the upper limb, 73 with injury to the lower limb and 49 controls. We found that the DASH score also measured disability in patients with injuries to the lower limb. Care must therefore be taken when attributing disability measured by the DASH score to injuries of the upper limb when problems are also present in the lower limb. Its inability to discriminate clearly between disability due to problems at these separate sites must be taken into account when using this instrument in clinical practice or research.

Does warming up prevent injury in sport? The evidence from randomised controlled trials?

BACKGROUND: The practice of warming up prior to exercise is advocated in injury prevention programs, but this is based on limited clinical evidence. It is hypothesised that warming up will reduce the number of injuries sustained during physical activity. METHODS: A systematic review was undertaken. Relevant studies were identified by searching Medline (1966-April 2005), SPORTDiscus (1966-April 2005) and PubMed (1966-April 2005). This review included randomised controlled trials that investigated the effects of warming up on injury risk. Studies were included only if the subjects were human, and only if they utilised other activities than simply stretching. Studies reported in languages other than English were not included. The quality of included studies was assessed independently by two assessors. RESULTS: Five studies, all of high quality (7-9 (mean=8) out of 11) reported sufficient data (quality score>7) on the effects of warming up on reducing injury risk in humans. Three of the studies found that performing a warm-up prior to performance significantly reduced the injury risk, and the other two studies found that warming up was not effective in significantly reducing the number of injuries. CONCLUSIONS: There is insufficient evidence to endorse or discontinue routine warm-up prior to physical activity to prevent injury among sports participants. However, the weight of evidence is in favour of a decreased risk of injury. Further well-conducted randomised controlled trials are needed to determine the role of warming up prior to exercise in relation to injury prevention.

A pilot randomised controlled trial of eccentric exercise to prevent hamstring injuries in community-level Australian Football.

Hamstring injuries are the most common injury sustained by Australian Football players. Eccentric training has been proposed as a potential preventative strategy. This pilot randomised controlled trial (RCT) evaluated the effectiveness of a pre-season eccentric training program for preventing hamstring injuries at the community level of Australian Football. Seven amateur clubs (n=220 players) were recruited. Players were randomised within clubs to the intervention (eccentric exercise) or control (stretching) groups and randomisation was stratified according to previous history of hamstring injury. Five exercise sessions were completed over a 12-week period, three during the pre-season and two during the first 6 weeks of the season. Compliance was recorded and players were monitored for the season to collect injury and participation data. There was no difference between the control (n=106) or intervention (n=114) groups with respect to baseline characteristics. Only 46.8% of all players completed at least two program sessions. Compliance was poorest for the intervention group. Intention-to-treat analysis suggested that players in the intervention group were not at reduced risk of hamstring injury (RR 1.2, 95% CI: 0.5, 2.8). When only control and intervention group players who participated in at least the first two sessions were analysed, 4.0% of intervention and 13.2% of control group players sustained a hamstring injury (RR 0.3, 95% CI: 0.1, 1.4; p=0.098). The findings suggest that a simple program of eccentric exercise could reduce the incidence of hamstring injuries in Australian Football but widespread implementation of this program is not likely because of poor compliance.

Inter-rater agreement on assessment of outcome within a trauma registry.

INTRODUCTION: To better evaluate the degree of ongoing disability in trauma patients, it has been recommended that trauma registries introduce routine long-term outcome measurement. One of the measures recommended for use is the Extended Glasgow Outcome Scale (GOS-E). However, few registries have adopted this measure and further research is required to determine its reliability with trauma populations. This study aimed to evaluate the inter-rater agreement of GOS-E scoring between an expert rater and trauma registry follow-up staff with a sample of detailed trauma case scenarios. METHODS: Sixteen trauma registry telephone interviewers participated in the study. They were provided with a written summary of 15 theoretical adult trauma cases covering a spectrum of disability and asked to rate each case using the structured GOS-E interview. Their ratings were compared with those of an expert rater in order to calculate the inter-rater agreement for each individual rater-expert rater pair. Agreement was reported as the percentage of agreement, the kappa statistic, and weighted kappa. A multi-rater kappa value was also calculated for agreement between the 16 raters. RESULTS: Across the 15 cases, the percentage of agreement between individual raters and the expert ranged from 63% to 100%. Across the 16 raters, the percentage of agreement with the expert rater ranged from 73-100% (mean=90%). Kappa values ranged from 0.65 to 1.00 across raters (mean=0.86) and weighted kappa values ranged from 0.73 to 1.00 (mean=0.89) The multi-rater kappa value was 0.78 (95% CI: 0.66, 0.89). CONCLUSIONS: Sixteen follow-up staff achieved 'substantial' to 'almost perfect' agreement with an expert rater using the GOS-E outcome measure to score 15 sample trauma cases. The results of this study lend support to the use of the GOS-E within trauma populations and highlight the importance of ongoing training where multiple raters are involved to ensure reliable outcome reporting. It is also recommended that the structured GOS-E interview guide be used to achieve better agreement between raters. Ensuring the reliability of trauma outcome scores will enable more accurate evaluation of patient outcomes, and ultimately, more targeted trauma care.

Health status and return to work in trauma patients at 3 and 6 months post-discharge: an Australian major trauma centre study.

INTRODUCTION: The aim of this study was to describe post-discharge outcomes, and determine predictors of 3 and 6 months health status outcomes in a population of trauma patients at an inner city major trauma centre. METHODS: This was a prospective cohort study of adult trauma patients admitted to this hospital with 3 and 6 months post-discharge outcomes assessment. Outcome measures were the Physical Component Scores (PCS) and Mental Component Scores (MCS) of the Short Form 12, EQ-5D, and return to work (in any capacity) if working prior to injury. Repeated measures mixed models and generalised estimating equation models were used to determine predictors of outcomes at 3 and 6 months. RESULTS: One hundred and seventy-nine patients were followed up. Patients with lower limb injuries reported lower mean PCS scores between 3 and 6 months (coefficient -4.21, 95 % CI -7.58, -0.85) than those without lower limb injuries. Patients involved in pedestrian incidents or assaults and those with pre-existing mental health diagnoses reported lower mean MCS scores. In adjusted models upper limb injuries were associated with reduced odds of return to work at 3 and 6 months (OR 0.20, 95 % CI 0.07, 0.57) compared to those without upper limb injuries. DISCUSSION: Predictors of poorer physical health status were lower limb injuries and predictors of mental health were related to the mechanism of injury and past mental health. Increasing injury severity score and upper limb injuries were the only predictors of reduced return to work. The results provide insights into the feasibility of routine post-discharge follow-up at a trauma service level.

Twelve-month mortality and functional outcomes in hip fracture patients under 65 years of age.

INTRODUCTION: There has been a recent call for improved functional outcome reporting in younger hip fracture patients. Younger hip fracture patients represent a different population with different functional goals to their older counterparts. Therefore, previous research on mortality and functional outcomes in hip fracture patients may not be generalisable to the younger population. The aims of this study were to report 12-month survival and functional outcomes in hip fracture patients aged <65 years and predictors of functional outcome. METHODS: Hip fracture patients aged <65years (range 17-64) registered by the Victorian Orthopaedic Trauma Outcomes Registry over four years were included and their 12-month survival and functional outcomes (Extended Glasgow Outcome Scale) reported. Ordered multivariable logistic regression was used to identify predictors of higher function. RESULTS: There were 507 patients enrolled in the study and of the 447 patients (88%) with 12-month outcomes, 24 (5%) had died. The majority of patients had no comorbidities or pre-injury disability and were injured via road trauma or low falls. 40% of patients sustained additional injuries to their hip fracture. 23% of patients had fully recovered at 12 months and 39% reported ongoing moderate disability. After adjusting for all key variables, odds of better function 12-months post-fracture were reduced for patients with co-morbidities, previous disability or additional injuries, those receiving compensation or injured via low falls. CONCLUSIONS: While 12-month survival rates were satisfactory in hip fracture patients aged under 65 years, their functional outcomes were poor, with less than one quarter having fully recovered 12 months following injury. This study provides new information about which patients may have difficulty returning to their pre-injury level of function. These patients may require additional or more intensive post-discharge care in order to fulfil their functional goals and continue to contribute productively to society.

Twelve-month outcomes following surgical repair of the Achilles tendon.

INTRODUCTION: Incidence of Achilles tendon rupture (ATR) has increased over recent years, and debate regarding optimal management has been widely documented. Most papers have focused on surgical success, complications and short term region-specific outcomes. Inconsistent use of standardised outcome measures following surgical ATR repair has made it difficult to evaluate the impact of ATR on a patient's health status post-surgery, and to compare this to other injury types. This study aimed to report the frequency of surgical repairs of the Achilles tendon over a five-year period within an orthopaedic trauma registry, and to investigate return to work (RTW) status, health status and functional outcomes at 12 months post-surgical repair of the Achilles tendon. METHODS: Two hundred and four adults registered by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) who underwent surgical repair of the Achilles tendon between July 2009 and June 2014 were included in this prospective cohort study. The Extended Glasgow Outcome Scale (GOS-E), 3-level European Quality of Life 5 Dimension measure (EQ-5D-3L), and RTW status 12 months following surgical ATR repair were collected through structured telephone interviews conducted by trained interviewers. RESULTS: At 12 months, 92% of patients were successfully followed up. Of those working prior to injury, 95% had returned to work. 42% of patients reported a full recovery on the GOS-E scale. The prevalence of problems on the EQ-5D-3L at 12 months was 0.5% for self-care, 11% for anxiety, 13% for mobility, 16% for activity, and 22% for pain. 16% of patients reported problems with more than one domain. The number of surgical repairs of the Achilles tendon within the VOTOR registry decreased by 68% over the five-year study period. CONCLUSIONS: Overall, patients recover well following surgical repair of the Achilles tendon. However, in this study, deficits in function persisted for over half of patients at 12 months post-injury. The decreased incidence of surgical Achilles tendon repair may reflect a change in practice at VOTOR hospitals whereby surgery may be becoming less favoured for initial ATR management.

Quality of care for patients with a fracture of the hip in major trauma centres: a national observational study.

AIMS: In this study, we aimed to determine whether designation as a major trauma centre (MTC) affects the quality of care for patients with a fracture of the hip. PATIENTS AND METHODS: All patients in the United Kingdom National Hip Fracture Database, between April 2010 and December 2013, were included. The indicators of quality that were recorded included the time to arrival on an orthopaedic ward, to review by a geriatrician, and to operation. The clinical outcomes were the development of a pressure sore, discharge home, length of stay, in-hospital mortality, and re-operation within 30 days. RESULTS: There were 289 466 patients, 49 350 (17%) of whom were treated in hospitals that are now MTCs. Using multivariable logistic and generalised linear regression models, there were no significant differences in any of the indicators of the quality of care or clinical outcomes between MTCs, hospitals awaiting MTC designation and non-MTC hospitals. CONCLUSION: These findings suggest that the regionalisation of major trauma in England did not improve or compromise the overall care of elderly patients with a fracture of the hip. TAKE HOME MESSAGE: There is no evidence that reconfiguring major trauma services in England disrupted the treatment of older adults with a fracture of the hip.

Risk factors for hamstring injuries in community level Australian football.

OBJECTIVES: To identify risk factors for hamstring injury at the community level of Australian football. METHODS: A total of 126 community level Australian football players participated in this prospective cohort study. To provide baseline measurements, they completed a questionnaire and had a musculoskeletal screen during the 2000 preseason. All were monitored over the season. Injury surveillance and exposure data were collected for the full season. Survival analysis was used to identify independent predictors of hamstring injury. RESULTS: A hamstring injury was the first injury of the season in 20 players (16%). After adjustment for exposure, increasing age and decreased quadriceps flexibility were identified as significant independent predictors of the time to sustaining a hamstring injury. Older age (> or =23 years) was associated with an increased risk of hamstring injury (RR 3.8; 95% confidence interval (CI) 1.1 to 14.0; p = 0.044). Players with increased quadriceps flexibility (as measured by the modified Thomas test) were less likely to sustain a hamstring injury (RR 0.3; 95% CI 0.1 to 0.8; p = 0.022). CONCLUSIONS: The findings of this study can be used in the development of hamstring injury prevention strategies and to identify Australian football players at increased risk of hamstring injury.

Incidence of serious injury and death during sport and recreation activities in Victoria, Australia.

BACKGROUND: Participation in sport and recreation is widely encouraged for general good health and the prevention of some non-communicable diseases. However, injury is a significant barrier to participation, and safety concerns are a factor in the decision to participate. An understanding of the sport/recreation activities associated with serious injury is useful for informing physical activity choices and for setting priorities for the targeting of injury prevention efforts. OBJECTIVES: To describe the epidemiology of serious injuries sustained in sport/recreation activities by adults in Victoria, Australia. METHODS: The Victorian State Trauma Registry and the National Coroner's Information Service were used to identify and describe sport/recreation related serious injuries, including deaths, occurring during the period July 2001 to June 2003. Age adjusted rates of serious injury and death were calculated using participation figures for each sport and general population data. RESULTS: There were 150 cases of serious injury and 48 deaths. The rates of serious injury and death were 1.8 and 0.6 per 100,000 participants per year respectively. Motor, power boat, and equestrian sports had the highest rates of serious injury. Most deaths were due to drowning. CONCLUSION: Although the risk of serious injury through sport/recreation participation is low, motor, power boat, and equestrian sports should be priorities for further research into injury prevention. Most sport/recreation related deaths are due to drowning, highlighting this area for prevention efforts.
