Establishing a Chinese older hip fracture registry for older patients: a Delphi study to define the focus and key variables for this registry.

A national hip fracture registry does not yet exist in China. This is the first to recommend a core variable set for the establishment of a Chinese national hip fracture registry. Thousands of Chinese hospitals will build on this and improve the quality of management for older hip fracture patients. The rapidly ageing population of China already experiences over half a million hip fractures every year. Many countries have developed national hip fracture registries to improve the quality of hip fracture management, but such a registry does not exist in China. The study is aimed at determining the core variables of a national hip fracture registry for older hip fracture patients in China. A rapid literature review was conducted to develop a preliminary pool of variables from existing global hip fracture registries. Two rounds of an e-Delphi survey were conducted with experts. The e-Delphi survey used a Likert 5-point scale and boundary value analysis to filter the preliminary pool of variables. The list of core variables was finalised following an online consensus meeting with the experts. Thirty-one experts participated. Most of the experts have senior titles and have worked in a corresponding area for more than 15 years. The response rate of the e-Delphi was 100% for both rounds. The preliminary pool of 89 variables was established after reviewing 13 national hip fracture registries. With two rounds of the e-Delphi and the expert consensus meeting, 86 core variables were recommended for inclusion in the registry. This study is the first to recommend a core variable set for the establishment of a Chinese national hip fracture registry. The further development of a registry to routinely collect data from thousands of hospitals will build on this work and improve the quality of management for older hip fracture patients in China.

Cost-effectiveness of a multidisciplinary co-management program for the older hip fracture patients in Beijing.

The multidisciplinary co-management program for geriatric patients with hip fracture is cost-effective in the Chinese population and it has the potential to be scaled up in China. INTRODUCTION: The study aimed to investigate the cost-effectiveness of a multidisciplinary co-management program for patients with hip fracture in China. METHODS: Hip fracture patients who were admitted to an orthopedic hospital in Beijing were included in the multidisciplinary co-management program. The cost-effectiveness of intervention was evaluated compared to the conventional management. A Markov microsimulation model was developed to simulate lifetime costs and effectiveness. Costs including intervention, hospitalization, medications, and long-term care costs were expressed using 2019 US dollars and the healthcare perspective was adopted. Effectiveness was evaluated using both 1-year mortality-averted and quality-adjusted life years (QALYs). Costs and effectiveness were discounted at 5% per annum. The willingness-to-pay (WTP) threshold was set at $26,481 per QALY gained which was three times gross domestic product (GDP) per capita in China. One-way and probabilistic sensitivity analyses were conducted. RESULTS: The lifetime cost for the conventional management (n = 1839) and intervention group (n = 1192) was $11,975 and $13,309 respectively. The lifetime QALYs were 2.38 and 2.45 years and the first-year mortality was 17.8% and 16.1%. The incremental cost-effectiveness ratio was $19,437 per QALY gained or $78,412 per 1-year mortality-averted. Given the Chinese WTP threshold, the intervention had a 78% chance being cost-effective. The cost-effectiveness of the intervention was sensitive to cost of intervention and the proportion of patients who underwent surgery within 48 h. CONCLUSIONS: The multidisciplinary co-management program for patients with hip fracture is cost-effective and it has the potential to be scaled up in the Chinese population.

Parenthood and risk of hip fracture: a 10-year follow-up prospective study of middle-aged women and men in China.

This prospective study of Chinese adults demonstrated an inverse J-shaped association of number of children with risk of hip fracture in both men and postmenopausal women aged 50 years or older. Women with 2 or 3 children and men with 4 children had the lowest risk of hip fracture. INTRODUCTION: Women have higher absolute risks of fracture than men, which is believed to reflect differences in oestrogen exposure. The aim of this study was to compare the associations of number of children with risk of hip fracture between men and women aged over 50 years. METHODS: The China Kadoorie Biobank (CKB) recruited 133,399 women and 110,296 men, aged 50 years or older between 2004 and 2008. During 10-year follow-up, 2068 participants (1394 women and 674 men) suffered a hip fracture. Cox regression analysis was used to estimate sex-specific adjusted hazard ratios (HRs) and 95% CI for incident hip fracture. RESULTS: Over 98% of both subsets of men and women aged 50 or older reported having children. Women who had 2 or 3 children had the lowest risks of hip fracture compared with other groups. Compared with nulliparous women, the adjusted HR for hip fracture were 0.89 (95% CI; 0.72, 1.10) for 1 child, 0.79 (0.70, 0.90) for 2 children, 0.79 (0.72, 0.87) for 3 children, 0.81 (0.72, 0.91) for 4 children, and 0.95 (0.83, 1.10) for those with 5 or more children. The associations of number of children with hip fracture were broadly consistent in men of a similar age. CONCLUSIONS: The concordant effects of the number of children with risk of hip fracture between men and women suggest that the lower risks in multiparous women are not due to differences in oestrogen exposure or other biological effects, but may reflect residual confounding by socioeconomic or lifestyle factors.

Opportunities for gender transformative approaches in a community-based drowning reduction program in Bangladesh.

BACKGROUND: Community-based programs in rural low-and middle-income country settings are well-placed to conduct gender transformative activities that aid program sustainability and catalyse wider social change, such as reducing gender inequities that in turn improve health outcomes. The Anchal program is a drowning prevention intervention for children aged 1-5 years old in rural Bangladesh. It provides community crèche-based supervision delivered by local trained paid-female volunteers. We aimed to identify the influence of the Anchal program on gender norms and behaviours in the community context, and the effects these had on program delivery and men and women's outcomes. METHODS: Qualitative in-depth interviews, focus group discussions and observations were conducted with program beneficiaries and providers. Gender outcomes were analysed using FHI 360's Gender Integration Framework. RESULTS: The Anchal program was found to be a gender accommodating program as it catered for communities' gender-based roles and constraints but did not actively seek to change underlying beliefs, perceptions and norms that led to these. The program in some cases enhanced the independence and status of female community staff. This changed perceptions of communities towards acceptable levels of physical mobility and community involvement for women. Conversely, gender affected program delivery by reducing the ability of female supervisory staff to engage with male community leaders. The double burden of wage and household labour carried by local female staff also limited performance and progression. Gender-based constraints on staff performance, attrition and community engagement affected efficiency of program delivery and sustainability. CONCLUSIONS: The Anchal program both adapted to and shaped community gender norms and roles. The program has well-established relationships in the community and can be leveraged to implement gender transformative activities to improve gender-based equity. Health programs can broaden their impacts and target social determinants of health like gender equity to increase program sustainability and promote equitable health outcomes.

Cost of injury care in India: cross-sectional analysis of National Sample Survey 2014.

BACKGROUND: Injuries account for nearly 10% of total deaths in India and this burden is likely to rise. We aimed to estimate the out-of-pocket (OOP) expenditure and catastrophic expenditure due to hospitalisation or outpatient care as a result of any injury and factors associated with incurring catastrophic expenditure. METHODS: Secondary analysis of nationally representative data for India collected by National Sample Survey Organization in 2014, reporting on health service utilisation and healthcare-related OOP expenditure by income quintiles and by type of health facility (public or private). RESULTS: The median expenditure per episode of hospitalisation due to any injury was US$156, and it was three times higher among the richest quintile compared with the poorest quintile (p<0.001). There was a significantly higher prevalence (p<0.001) of catastrophic expenditure among the poorest quintile (32%) compared with the richest (21%). Mean private sector OOP hospitalisation expenditure was five times higher than in the public sector (p<0.001). Medicines accounted for 37% and 58% of public sector hospitalisation and outpatient care, respectively. Patients treated in a private facility, hospitalised for over 7 days, in the poorest wealth quintiles and of general caste had higher odds of incurring catastrophic expenditure. CONCLUSION: People who sustain an injury have a high risk of catastrophic household expenditure, particularly for those in lowest income quartiles. There is a clear need for publicly funded risk protection mechanisms targeting the poor. Promotion of generic medicines and subsidisation for the poorest wealth quintile may also reduce OOP expenditure in public sector facilities.

The epidemiology and characteristics of injuries to under 5's in a secondary city in Uganda: a retrospective review of hospital data.

Child injuries are largely preventable yet cause significant mortality and morbidity globally. Injury data from low-income countries is limited for children under the age of 5 and therefore the current understanding of the magnitude of injuries in this age group is low. Hospital-based registries are one mechanism by which injury data can be gathered. This paper presents findings from a retrospective hospital record review of 4 hospitals in Jinja, a rural setting in Uganda, involving the extraction of data for children under the age of 5-years who sustained an injury during a 6-month period in 2019. A total of 225 injury cases were retrieved from the hospitals. Over half (57.3%) of the events occurred among males. The majority (92%) suffered one injury per injury event. Most of the injuries occurred among those aged 13 to 24 months (32.9%). Burns (32%) and cuts (20%) were the most common cause of injury. This study presents a hospital-based analysis of injuries amongst under 5's in rural Uganda. It provides information on the characteristics of children entering healthcare facilities in Uganda and highlights the burden of paediatric injuries in the hospital setting.

Understanding novice driver policy agenda setting.

BACKGROUND: Despite the acute impact of road trauma involving novice drivers, there have been few efforts to identify the main factors influencing the novice driver policy agenda. Increasing the transparency of such policy dynamics may help inform future novice driver policy agenda-setting processes, as well as those in other public health settings. METHODS: Forty interviews were conducted between 2007 and 2009 with individuals involved in novice driver policy debates and processes in four Australian states. RESULTS: An increasing body of positive evaluations from other jurisdictions was seen to provide an initial stimulus for Australian novice driver policy activities. The dissemination of evidence by researchers, lobbying and advocacy by other influential stakeholders, and media reporting of multiple-fatality novice driver crashes were seen as other factors central to policy agenda setting. CONCLUSIONS: Australian graduated driver licensing (GDL) policy initiatives may only be acted upon once adequate political support is identified in terms of community demand for action and public acceptance of GDL policy in neighboring states. As such, researcher encouragement of community support for unpopular evidence-based policies during windows of opportunity for policy reform may act as an influential agenda-setting force.

Population-based estimates of injuries in Sri Lanka.

BACKGROUND: Injuries are the leading cause of public hospital admission in Sri Lanka. Data on injury epidemiology to plan prevention programmes to reduce injury burden are not readily available. OBJECTIVES: To assess the incidence of various types of injuries in the Galle district, Sri Lanka. METHODS: 9568 individuals of all ages were selected from 2000 households in a population-based cross-sectional survey using a stratified cluster sampling technique. Data on non-fatal injuries in the last 30 days irrespective of severity, fatal injuries and those that resulted in disability in the last 12 months were documented. Proxy data were used for half of the injury cases. RESULTS: 195 (2%) individuals reported non-fatal injuries during the last 30 days, giving an age-sex-urban-rural adjusted annual incidence of 24.6 per 100 population. The leading causes of non-fatal injuries were falls (adjusted annual incidence 6.7 per 100 population, 95% CI 6.0 to 7.3) and mechanical injuries (6.3; 95% CI 5.7 to 6.8), followed by road traffic injuries (4.9; 95% CI 4.4 to 5.5). 114 (58.5%) individuals needed outpatient care and 50 (25.6%) needed inpatient care for their injuries. The annual injury mortality rate and disability rate were 177 (95% CI 72 to 283) and 290 (95% CI 250 to 330) per 100,000 population, respectively. CONCLUSIONS: Nearly one in four people reported non-fatal injury; the majority sought medical attention in this population. It is important to utilise injury epidemiology to develop and implement interventions to reduce the burden of injuries in the population and on the hospitals in Sri Lanka.

Disseminating best-evidence health-care to Indigenous health-care settings and programs in Australia: identifying the gaps.

Indigenous Australians experience a disproportionately greater burden of harm from smoking, poor nutrition, alcohol misuse and physical inactivity (SNAP risk factors) than the general Australian population. A critical step in further improving efforts to reduce this harm is to review existing efforts aimed at increasing the uptake of evidence-based interventions in Indigenous-specific health-care settings and programs. This study systematically identifies and reviews published Indigenous-specific dissemination studies targeting SNAP interventions. An electronic search of eight databases and a manual search of reference lists of previous literature reviews were undertaken. Eleven dissemination studies were identified for review: six for nutrition and physical activity as a component of diabetes care, three for alcohol and two for smoking. The majority of studies employed continuing medical education (n = 9 studies), suggesting that improving health-care providers' knowledge and skills is a focus of current efforts to disseminate best-evidence SNAP interventions in Indigenous health-care settings. Only two studies evaluated reminder systems, despite their widespread use in Indigenous-specific health-care services, and only one study employed academic detailing, despite its cost-effectiveness at modifying health-care provider behavior. There is a clear need for more Indigenous-specific dissemination research targeting the uptake of secondary prevention and to establish reliable and valid measures of Indigenous-specific health-care delivery, in order to determine which dissemination strategies are most likely to be effective in Indigenous health-care settings and programs.

Helmets for preventing injury in motorcycle riders.

BACKGROUND: Motorcycle crash victims form a high proportion of those killed or injured in road traffic crashes. Injuries to the head, following motorcycle crashes, are a common cause of severe morbidity and mortality. It seems intuitive that helmets should protect against head injuries but it has been argued that motorcycle helmet use decreases rider vision and increases neck injuries. This review will collate the current available evidence on helmets and their impact on mortality, and head, face and neck injuries following motorcycle crashes. OBJECTIVES: To assess the effects of wearing a motorcycle helmet in reducing mortality and head and neck injury following motorcycle crashes. SEARCH STRATEGY: We searched the Cochrane Injuries Group Specialised Register, Cochrane Central Register of Controlled Trials (The Cochrane Library issue 2, 2007), MEDLINE (up to April 2007), EMBASE (up to April week 16, 2007), CINAHL (January 1982 to February 2003), TRANSPORT (up to issue 12, 2006) (TRANSPORT combines the following databases: Transportation Research Information Services (TRIS) International Transport Research Documentation (ITRD) formerly International Road Research Documentation (IRRD), ATRI (Australian Transport Index) (1976 to Feb 2003), Science Citation Index were searched for relevant articles. Websites of traffic and road safety research bodies including government agencies were also searched. Reference lists from topic reviews, identified studies and bibliographies were examined for relevant articles. SELECTION CRITERIA: We considered studies that investigated a population of motorcycle riders who had crashed, examining helmet use as an intervention and with outcomes that included one or more of the following: death, head, neck or facial injury. We included any studies that compared an intervention and control group. Therefore the following study designs were included: randomised controlled trials, non-randomised controlled trials, cohort, case-control and cross-sectional studies. Ecological and case series studies were excluded. DATA COLLECTION AND ANALYSIS: Two authors independently screened reference lists for eligible articles. Two authors independently assessed articles for inclusion criteria. Data were abstracted by two independent authors using a standard abstraction form. MAIN RESULTS: Sixty-one observational studies were selected of varying quality. Despite methodological differences there was a remarkable consistency in results, particularly for death and head injury outcomes. Motorcycle helmets were found to reduce the risk of death and head injury in motorcyclists who crashed. From four higher quality studies helmets were estimated to reduce the risk of death by 42% (OR 0.58, 95% CI 0.50 to 0.68) and from six higher quality studies helmets were estimated to reduce the risk of head injury by 69% (OR 0.31, 95% CI 0.25 to 0.38). Insufficient evidence was found to estimate the effect of motorcycle helmets compared with no helmet on facial or neck injuries. However, studies of poorer quality suggest that helmets have no effect on the risk of neck injuries and are protective for facial injury. There was insufficient evidence to demonstrate whether differences in helmet type confer more or less advantage in injury reduction. AUTHORS' CONCLUSIONS: Motorcycle helmets reduce the risk of death and head injury in motorcycle riders who crash. Further well-conducted research is required to determine the effects of helmets and different helmet types on mortality, head, neck and facial injuries. However, the findings suggest that global efforts to reduce road traffic injuries may be facilitated by increasing helmet use by motorcyclists.

Reducing the burden of road traffic injury: translating high-income country interventions to middle-income and low-income countries.

OBJECTIVE: To increase seat belt restraint use in Guangzhou City, People's Republic of China. DESIGN: Comparison group pre-test, post-test design. SETTING: Guangzhou City. INTERVENTIONS: Interventions to increase the prevalence of seat belt use in high-income countries (enhanced training and enforcement practices along with raising of public awareness) were adapted and implemented in Guangzhou. The prevalence of seat belt use was determined before and after the introduction of the 12-month intervention. Seat belt prevalence was also examined over the same time period in the neighboring city of Nanning, and an incremental cost-effectiveness analysis of the intervention was undertaken. MAIN OUTCOME MEASURES: Prevalence rates and incremental cost effectiveness ratios. RESULTS: A 12% increase in seat belt use was observed in Guangzhou over the study period, increasing from a prevalence of 50% before (error range 30-62%) to 62% after (error range 60-67%) (p<0.001) the intervention; an absolute change difference between the intervention and reference city of 20% was achieved. The incremental cost-effectiveness ratio of the intervention was yen 3246 (US dollars 418) per disability-adjusted life year saved. CONCLUSIONS: This city-wide intervention demonstrates that it is possible to increase the prevalence of seat belt use using similar methods to those used in high-income countries and, importantly, that such an approach is cost-effective.

The burden of fatal and non-fatal injury in rural India.

BACKGROUND: Little is known about the burden or causes of injury in rural villages in India. OBJECTIVE: To examine injury-related mortality and morbidity in villages in the state of Andhra Pradesh, India. METHODS: A verbal-autopsy-based mortality surveillance study was used to collect mortality data on all ages from residents in 45 villages in 2003-2004. In early 2005, a morbidity survey in adults was carried out using stratified random sampling in 20 villages. Participants were asked about injuries sustained in the preceding 12 months. Both fatal and non-fatal injuries were coded using classification methods derived from ICD-10. RESULTS: Response rates for the mortality surveillance and morbidity survey were 98% and 81%, respectively. Injury was the second leading cause of death for all ages, responsible for 13% (95% CI 11% to 15%) of all deaths. The leading causes of fatal injury were self-harm (36%), falls (20%), and road traffic crashes (13%). Non-fatal injury was reported by 6.7% of survey participants, with the leading causes of injury being falls (38%), road traffic crashes (25%), and mechanical forces (16.1%). Falls were more common in women, with most (72.3%) attributable to slipping and tripping. Road traffic injuries were sustained mainly by men and were primarily the result of motorcycle crashes (48.8%). DISCUSSION: Injury is an important contributor to disease burden in rural India. The leading causes of injury-falls, road traffic crashes, and suicides-are all preventable. It is important that effective interventions are developed and implemented to minimize the impact of injury in this region.

Using emergency trauma team activations to measure trauma activity and injury severity: 10 years of experience using an Australian major trauma centre registry.

OBJECTIVES: To describe the outcomes of Emergency Department trauma team activations over a 10-year period with respect to injury severity and hospital length of stay. METHODS: This was a retrospective study using trauma registry data at a single Major Trauma Centre in Australia. All trauma team activations and arrivals on pre-hospital major trauma (T1) protocol recorded in the trauma registry between June 2006 and July 2016 were included. The outcome of interest was major trauma, defined as an Injury Severity Score (ISS) >12 or length of stay >3 days or requiring urgent operative intervention or admission to the Intensive Care Unit following trauma. RESULTS: A total of 9876 hospital trauma activations were analysed from January 2006 to June 2016. Of these 53.3% were admitted as an in-patient and 16.6% were classified as having an ISS >15. Major trauma occurred in 38% of cases. With respect to hospital utilisation, patients with an ISS <16 accounted for around half of total cumulative in-patient bed-days. CONCLUSIONS: Analysis of data from trauma team activations in ED has allowed a description of trauma activity and hospital bed day utilisation as a function of injury severity. The results confirm that those with minor trauma accounted for the vast majority of cases and around half of all hospital in-patient bed-days.

Where to from here? A quality improvement project investigating burns treatment and rehabilitation practices in India.

OBJECTIVE: To describe the capacity of the Indian healthcare system in providing appropriate and effective burns treatment and rehabilitation services. RESULTS: Health professionals involved in burns treatment or rehabilitation at seven hospitals from four states in India were invited to participate in consultative meetings. Existing treatment and rehabilitation strategies, barriers and enablers to patient flow across the continuum of care and details on inpatient and outpatient rehabilitation were discussed during the meetings. Seventeen health professionals from various clinical backgrounds were involved in the consultation process. Key themes highlighted (a) a lack of awareness on burn first aid at the community level, (b) a lack of human resource to treat burn injuries in hospital settings, (c) a gap in burn care training for medical staff, (d) poor hospital infrastructure and (e) a variation in treatment practices and rehabilitation services available between hospitals. A number of opportunities exist to improve burns treatment and rehabilitation in India. Improvements would most effectively be achieved through promoting multidisciplinary care across a number of facilities and service providers. Further research is required to develop context-specific burn care models, determining how these can be integrated into the Indian healthcare system.

Rehabilitation practices for burn survivors in low and middle income countries: A literature review.

OBJECTIVE: To systematically review the delivery and effectiveness of rehabilitation for burn survivors in low and middle income countries (LMIC). METHODS: We systematically searched the literature through 11 electronic databases and the reference lists of relevant studies. Studies were suitable for inclusion if they were primary research with a focus on burns rehabilitation in LMIC settings describing either service delivery or treatment effectiveness. No time, design or other limitations were applied, except English language. RESULTS: Of 226 studies identified, 17 were included in the final review, including 7 from India. The results were summarised in a narrative synthesis as the studies had substantial heterogeneity and small sample sizes, with many relying on retrospective data from non-representative samples with no control groups. Most studies (12) described service delivery and 5 examined the effectiveness of different types of rehabilitation. Multiple studies stressed the need for rehabilitation and multidisciplinary teams for burns management. CONCLUSIONS: The published research on burns rehabilitation is very limited and little is known about current practices in LMIC settings. In order to inform policy and service delivery, the effectiveness, feasibility and sustainability of current services needs to be investigated.

The psychological impact of traffic injuries sustained in a road crash by bicyclists: A prospective study.

OBJECTIVE: The objective of this study was to investigate the psychological impact of traffic injuries in bicyclists (cyclists) in comparison to car occupants who also sustained traffic injuries. Factors predictive of elevated psychological distress were also investigated. METHODS: An inception cohort prospective design was used. Participants included cyclists aged ≥17 years (mean age 41.7 years) who sustained a physical injury (n = 238) assessed within 28 days of the crash, following medical examination by a registered health care practitioner. Injury included musculoskeletal and soft tissue injuries and minor/moderate traumatic brain injury (TBI), excluding severe TBI, spinal cord injury, and severe multiple fractures. Assessment also occurred 6 months postinjury. Telephone-administered interviews assessed a suite of measures including sociodemographic, preinjury health and injury factors. Psychological impact was measured by pain catastrophization, trauma-related distress, and general psychological distress. The psychological health of the cyclists was compared to that of the car occupants (n = 234; mean age 43.1 years). A mixed model repeated measures analysis, adjusted for confounding factors, was used to determine differences between groups and regression analyses were used to determine contributors to psychological health in the cyclists 6 months postinjury. RESULTS: Cyclists had significantly better psychological health (e.g., lower pain catastrophizing, lower rates of probable posttraumatic stress disorder [PTSD], and lower general distress levels) compared to car occupants at baseline and 6 months postinjury. Factors predictive of cyclists' psychological distress included younger age, greater perceived danger of death, poorer preinjury health, and greater amount of time in hospital after the injury. CONCLUSIONS: These data provide insight into how cyclists perceive and adjust to their traffic injuries compared to drivers and passengers who sustain traffic injuries, as well as direction for preventing the development of severe psychological injury. Future research should examine the utility of predictors of psychological health to improve recovery.

Predictors of older drivers' involvement in rapid deceleration events.

Rapid deceleration occurs when substantial force slows the speed of a vehicle. Rapid deceleration events (RDEs) have been proposed as a surrogate safety measure. As there is concern about crash involvement of older drivers and the effect of age-related declining visual and cognitive function on driving performance, we examined the relationship between RDEs and older driver's vision, cognitive function and driving confidence, using naturalistic driving measures. Participants aged 75 to 94 years had their vehicle instrumented for 12 months. To minimise the chance of identifying false positives, accelerometer data was processed to identify RDEs with a substantial deceleration of >750 milli-g (7.35m/s2). We examined the incidence of RDEs amongst older drivers, and how this behaviour is affected by differences in age; sex; visual function, cognitive function; driving confidence; and declines over the 12 months. Almost two-thirds (64%) of participants were involved in at least one RDE, and 22% of these participants experienced a meaningful decline in contrast sensitivity during the 12 months. We conducted regression modelling to examine associations between RDEs and predictive measures adjusted for (i) duration of monitoring and (ii) distance driven. We found the rate of RDEs per distance increased with age; although, this did not remain in the multivariate model. In the multivariate model, we found older drivers who experienced a decline in contrast sensitivity over the 12 months and those with lower baseline driving confidence were at increased risk of involvement in RDEs adjusted for distance driven. In other studies, contrast sensitivity has been associated with increased crash involvement for older drivers. These findings lend support for the use of RDEs as a surrogate safety measure, and demonstrate an association between a surrogate safety measure and a decline in contrast sensitivity of older drivers.

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.

Diabetes and risk of fracture: The Blue Mountains Eye Study.

OBJECTIVE: To examine associations between measures of diabetes and risk of fracture in a population-based sample of older Australians. RESEARCH DESIGN AND METHODS: This was a prospective study of 3,654 subjects aged 49 years and older who were residents in the Blue Mountains, west of Sydney, Australia. At baseline, subjects were asked questions about history and treatment of diabetes, and fasting blood samples were taken. Photographs were taken of the retina and lens to grade retinopathy and cataract. Details of fractures (excluding rib and vertebral fractures) were collected by a combination of self-report and medical record searches; all fractures were radiologically confirmed. RESULTS: After 2 years of follow-up, we found that several diabetes-related factors were significantly associated (in multivariate models) with increased risk of all fractures combined, including presence of diabetic retinopathy (adjusted RR 5.4, 95% CI 2.7-10.8), diabetes duration > or = 10 years (3.3, 1.3-8.2), cortical cataract involving > or = 25% of the lens area (2.5, 1.3-4.7), and insulin treatment (5.9, 2.6-13.5). The proximal humerus was the only individual fracture site associated with diabetes. Diabetic retinopathy (10.3, 2.2-48.0), diabetes duration (for > or = 10 years duration; 11.4, 2.4-54.2), and insulin treatment (18.8, 4.0-88.7) were all associated with proximal humerus fracture. CONCLUSIONS: These data suggest a significantly increased risk of fracture associated with diabetic retinopathy, advanced cortical cataract, longer diabetes duration, and insulin treatment. However, there are some shortcomings in this study that may limit these findings.
