- Description: Summary: Survival after hospitalisation for hip fracture by age group and sex relative to survival in the general population was assessed in people aged 65+. Men had double the risk of death compared with women to 1 year, but age effects lasted only to 3 months. Clinical outcomes need to be improved. Introduction: We assessed the relative survival of hospitalised fall-related hip fracture patients aged 65+ years leaving hospital in New South Wales, Australia, between July 2000 and December 2003. Method: We carried out a population-based study of all hospital separations for NSW residents with a principal diagnosis of hip fracture (ICD-10-AM S72.0 to S72.2) and first external cause of fall (ICD-10-AM codes W00 to W19), linked to NSW death data. A total of 16,836 cases were included. Relative survival 3 to 36 months post-admission by 10-year age groups and sex was calculated, using NSW life tables for 2002-2004. Relative excess risk was modelled using a generalised linear model with Poisson error structure, using the life table data. Results: One-year cumulative relative survival in 65- to 74-year-olds was 82% (men), 90% (women); in 85+-year-olds 65% (men), 80% (women). Men have a relative excess risk of death of 2.2 (95% CI 2.03-2.38) times that of women. Only 21% of deaths mention the hip fracture as contributing to death. Conclusion: There is a need to reduce the number of hip fractures and improve clinical outcomes for older people hospitalised with hip fractures. © 2008 International Osteoporosis Foundation and National Osteoporosis Foundation.

- Description: In this study, the recently introduced International Classification of Disease, 10th revision, code for hot tap water scalds was used to examine the epidemiology of these cases and other scalds injuries in children younger than 5 years of age and adults aged 65 years and older. Although the trunk was the most common area in which scalds occurred, young children were more likely to sustain head and neck scalds (15%, 95% confidence interval 10.8-18.3) because of hot tap water than older people (2%, 95% confidence interval 0.2-4.4). Hospital separation rates for hot water scalds decreased significantly during the study period in both boys ([chi]2 = 15.6, df = 1, P < .001) and girls ([chi]2 = 5.6, df = 1, P < .001) who were younger than 5 years of age, which might be attributable to the introduction of new standards regulating the provision of hot tap water to various buildings. The severity of scalds cases did not seem to be correlated with the length of hospital stay, which remained unchanged in both age groups.

- Description: Information about the regional population distribution of sports injury rates is important for the identification of priority groups for injury prevention and sports medicine service delivery. This study describes the relationship between regional measures of social disadvantage (socio-economic index for areas, SEIFA) and remoteness (accessibility/remoteness index of Australia, ARIA) and the incidence of sport/leisure hospitalisation episodes for 2003-2004. All hospital separations, of New South Wales (NSW, Australia) residents, with an ICD-10-AM principal diagnosis indicating an injury and an activity code indicating sport/leisure activity were included. Age-standardised hospitalisation rates were calculated across SEIFA and ARIA categories. There was no clear trend in hospitalisation rates across SEIFA quintiles, with rates ranging from a low of 150.3/100,000 population (95% CI: 145.5-155.2) in the quintile of most disadvantage to a high of 201.8/100,000 population (196.1-207.4) in the middle quintile. In contrast, there was a strong positive and significant trend across ARIA groups (p < 0.001) with rates ranging from a low of 156.2/100,000 population (153.2-159.2) in the most urban areas to a high of 335.5/100,000 population (306.5-364.6) in remote areas. Reasons for these trends are unclear but may include differences in medical and allied health service provision, sport/leisure infrastructure and opportunities across regions or differential participation in sport across NSW. Further investigations into why remote and very remote areas, in particular, have such high rates, including exploration of participation rates, sport/leisure opportunity delivery factors and the provision of sports medicine services need to be undertaken before injury rates can be reduced in these areas. © 2008 Sports Medicine Australia.

- Description: Summary: Policy decisions about the allocation of current and future resources should be based on the most accurate predictions possible. A functional data analysis (FDA) approach improves the understanding of current trends and future incidence of injuries. FDA provides more valid and reliable long-term predictions than commonly used methods. Introduction: Accurate information about predicted future injury rates is needed to inform public health investment decisions. It is critical that such predictions derived from the best available statistical models to minimise possible error in future injury incidence rates. Methods: FDA approach was developed to improve long-term predictions but is yet to be widely applied to injury epidemiology or other epidemiological research. Using the specific example of modelling age-specific annual incidence of fall-related severe head injuries of older people during 1970-2004 and predicting rates up to 2024 in Finland, this paper explains the principles behind FDA and demonstrates their superiority in terms of prediction accuracy over the more commonly reported ordinary least squares (OLS) approach. Results: Application of the FDA approach shows that the incidence of fall-related severe head injuries would increase by 2.3-2.6-fold by 2024 compared to 2004. The FDA predictions had 55% less prediction error than traditional OLS predictions when compared to actual data. Conclusions: In summary, FDA provides more accurate predictions of long-term incidence trends than commonly used methods. The production of FDA prediction intervals for future injury incidence rates gives likely guidance as to the likely accuracy of these predictions. © 2010 International Osteoporosis Foundation and National Osteoporosis Foundation.

- Description: The epidemiology and trends in wrist fracture admissions to public and private acute hospitals in New South Wales (NSW), Australia, between July 1993 and June 2003 were examined using routinely collected hospital separations statistics. During the study period, the number of hospital separations for wrist fractures increased by 71% in men, an average yearly increase of 6.5%, and by 43% in women, an average yearly increase of 3.9%. A modest, but significant, increase in age-specific and age-standardised hospitalisation rates for wrist fractures was also observed. Whilst the majority of wrist fractures were due to falls, the proportion of falls-related wrist fractures decreased significantly over time. This decrease was more pronounced in males and was accompanied by a rise in the proportion of wrist fractures resulting from high energy mechanisms such as transport, violence and machinery-related incidents. The difference in hospitalised wrist fracture rates between men and women could not be explained solely on the basis of the role played by osteoporosis, indicating the need for more research to improve our understanding of the underlying factors of this type of fracture in older people.

- Description: Hamstring injuries are the most common injury sustained by elite Australian football players and result in substantial costs because of missed training time, unavailability for matches and lost player payments. Evidence to support proposed risk factors for hamstring injury is generally lacking, limiting the development of appropriate prevention strategies. To identify intrinsic risk factors for hamstring injury at the elite level of Australian football. A prospective cohort of 222 players underwent baseline measurement in the form of a self-report questionnaire and a musculo-skeletal screen during the pre-season period of the 2002 Australian football season. Injury surveillance and exposure data were collected for the full season. Logistic regression analyses were used to identify independent predictors of hamstring injury in this group of players. Thirty-one players sustained a hamstring injury. A past history (previous 12 months) of hamstring injury and increasing age were found to be independent predictors of hamstring injury. Older players and those with a previous history of hamstring injury are target groups for further research and implementation of injury prevention strategies. Restricted ankle dorsiflexion range of movement warrants consideration in the development of prevention programs for hamstring injury.

- Description: Sport is an important context for physical activity and it is critical that safe environments are provided for such activity. Sports safety is influenced by the presence of sports ground environmental hazards such as ground hardness, poorly maintained playing fields, surface irregularities and the presence of debris/rubbish. To reduce injury risk, sports governing bodies need to ensure regular assessment of grounds safety and the removal of identified hazards. This study describes sports ground safety guidelines and recommendations of a sample of sports governing bodies and provides recommendations for how they could be improved. Semi-structured key informant interviews were conducted with nominees of state governing bodies for Australian football, cricket, soccer and hockey. The use of matchday checklists to identify ground hazards, as mandated by insurance companies was widely promoted across all levels of play. Sports governing bodies had more direct involvement in assessing grounds used for higher level of play, than grounds used for community or junior sport. There was a general presumption that identified hazards on community grounds would be corrected by local councils or clubs before anyone played on them, but this was rarely monitored. Sports governing bodies run the risk of being negligent in their duty of care to sports participants if they do not formally monitor the implementation of their ground safety polices and guidelines. There is also further scope for sports bodies to work closely with insurers to develop ground safety assessment guidelines specific to their sport. © 2008 Sports Medicine Australia.

- Description: Participation in appropriate exercise can help reduce the risk of falls and falls injury in older people. Delivery of population-level exercise interventions requires an expert workforce with skills in development and delivery of group exercise programs and prescription of individually targeted exercise. This study assessed the current knowledge of university exercise science students (as future exercise professionals) across different levels of study. A structured survey designed to assess knowledge in relation to falls in older people and exercise prescription for falls prevention was administered during second, third and fourth year lectures in seven Australian universities. Students' knowledge was assessed as the percent of correct responses. Overall, 566 students completed the survey and knowledge levels increased significantly with study year. Mean knowledge levels were significantly <70%, indicating limited knowledge. They were lowest for falls risk factor questions and highest for issue/cost related questions in second and third year students. Fourth year students had best knowledge about falls interventions and this was the only group and topic with a mean score >70%. In conclusion, knowledge about falls and exercise prescription for falls prevention in current students does not meet a desired competency level of 70% and is therefore insufficient to ensure an adequately equipped future workforce in this area. There is a clear need for the development and widespread delivery of an evidence-based "exercise for falls prevention" curriculum module for exercise professionals. © 2009 Sports Medicine Australia.

- Description: Introduction: Published netball data have indicated that the ankle and knee are common sites for injury, often as a result of incorrect landing technique. Promising results have been demonstrated across various sports using training intervention studies designed to reduce lower limb injury rates. This qualitative study examines the barriers and facilitators towards the implementation of a 6-week landing intervention program (“Down to Earth”) by coaches of junior netball teams. Methodology: Coaches of junior teams (n = 30) were recruited prior to the competition season (October 2007 to March 2008) and attended a workshop where the coaching requirements of the program were demonstrated. Coaches were instructed to implement the program at training, noting any issues regarding program compliance. Pre- and post-season surveys modelled on the Theory of Planned Behaviour were used to indicate coaches’ attitudes, perceived social norms and behavioural control towards safe landing programs in netball. Retention of correct landing principles was assessed and barriers and facilitators for broader implementation among junior netball coaches were determined. Results and discussion: Results will be presented to indicate how coaches’ attitudes and knowledge towards landing intervention programs can assist in the development of an effective implementation strategy of a training injury prevention intervention, to a broader netball community. An example of feedback provided was”…we have noticed quite an improvement in the kids, and their landing and balancing, so it is all been worth while. We were also discussing…about including the program into our junior training next year and how best to do this”.

- Description: Objective: Despite the popularity of cricket at the junior community level, few studies have described injuries for this level of play. This study describes the epidemiology of cricket injuries in junior club cricket across three playing seasons to identify priorities for prevention. Design: Prospective on-field injury data collection during match observation of acute injuries. Pre and post observational evaluation of mandatory helmet wearing. Setting: The Sutherland Shire Junior Cricket Association, New South Wales, Australia during the 2002-03, 2003-04 and 2004-05 playing seasons. Participants: All junior teams (Under 8 (U8)-U16). Intervention: Compulsory headgear introduced for all batters before the 2004-05 season. Main outcome measures: Frequency of injury according to age level, grade of play and playing position, and injury rates per 100 registered players. Results: 155 injuries were reported. No U8 player sustained an injury, and injury frequency increased with age. Traditional cricket was associated with more injuries than modified cricket. At each age level, the most skilled players had the lowest frequency of injury. Overall, batting accounted for 49% of all injuries and 29% occurred when fielding; contact with a moving ball was responsible for 55% of injuries. The most commonly injured body region was the face (20%), followed by the hand (14%). In batters, the frequency of head/neck/facial injuries fell from 62% in 2002/03 to 35% in 2003-04 to just 4% in 2004-05 after headgear use was compulsory. Conclusions: Injury rates in junior players are low, but increase with age and level of play. Use of protective headgear, particularly by batters, leads to a significant reduction in injuries.

- Description: Scalds from hot tap water are serious injuries that are potentially preventable by restricting the temperature of hot tap water delivery. In July 1999, regulations were introduced in NSW to require that all new hot water installations deliver water at temperatures not exceeding 50 °C to sanitary fixtures. This study investigates trends in hot tap water scald injury hospitalisations following the introduction of these regulations. Hot tap water scald cases for 1999-2007 were identified from hospitalisation data for all public and private hospitals in NSW. To investigate hot tap water scald hospitalisations over time, negative binomial regression analysis was performed. There were 845 hospitalisations for hot tap water scalds in NSW over the period of the study. Hospital admission rates for hot tap water scalds decreased by an estimated 6% (3.2-8.5, 95%CI) per year since the introduction of regulations. While those most at risk were infants, toddlers and the elderly, almost a third of hospitalisations were for adults (25-64 years). The majority of hot tap water scalds were sustained at home and a further 4% occurred in a residential institute or school. The majority of scalds were severe, and a quarter required admission for longer than a week. The introduction of regulations in NSW appears to have had a positive impact on the rates of hospitalisations for hot tap water scalds; however, scalds continue to cause significant morbidity and mortality. This highlights the need for a review of the scope and implementation of the existing regulations and ongoing education of the general public to the dangers of hot tap water. © 2009 Elsevier Ltd and ISBI.

After adjustment for season, day-of-week effects, long-term trend and autocorrelation, hip fracture rates are higher in both males and females aged 75+ years when there is a lower air temperature. This study investigated whether there was an association between fall-related hip fracture hospitalisations and air temperature at a day-to-day level, after accounting for seasonal trend and autocorrelation. Observation-driven Poisson regression models were used to investigate mean daily air temperature and fall-related hip fracture hospitalisations for the period 1 July 1998 to 31 December 2004, inclusive, in the Sydney region of New South Wales, Australia, which has a population of 4 million people. Lower daily air temperature was significantly associated with higher fall-related hip fracture hospitalisations in 75+-year-olds: men aged 75-84 years, rate ratio (RR) for a 1A degrees C increase in temperature of 0.98 with 95% confidence interval (0.96, 0.99), men 85+ years RR = 0.98 (0.96, 1.00), women 75-84 years RR = 0.99 (0.98, 1.00), women 85+ years RR = 0.98 (0.97, 0.99). Moreover, there were fewer hospitalisations on weekends compared to weekdays ranging from RR = 0.81 (0.73, 0.90) in women aged 65-74 years to RR = 0.89 (0.80, 0.98) in men aged 85+ years. After adjustment for season, day-of-week effects, long-term trend and autocorrelation, fall-related hip fracture hospitalisation rates are higher in both males and females aged 75+ years when there is a lower air temperature.

- Description: Objectives: Population modelling holds considerable promise for identifying the most efficient and cost-effective falls prevention measures, but the outcomes need to be in a readily useable form. This paper describes an iterative, collaborative process undertaken by researchers and falls prevention policy officers to develop such a format for falls prevention intervention evidence. Methods: The researchers developed a draft template that underwent several iterations and improvements, through three collaborative consultations with policy officers. Results: Although the researchers initially identified many key information needs, active engagement with policy officers ensured that policy requirements were met and that the value of the reporting formats for policy decision-making was maximised. Importantly, they highlighted the need to articulate underlying modelling assumptions clearly. The resulting formats, with complete data, were given to policy officers to inform their local jurisdictional policy decisions. Conclusions: There is strong benefit in researchers and policy officers collaborating to develop optimal formats for presenting scientific evidence to inform policy decisions. Such a process can reduce concerns of researchers that evidence is not incorporated into policy decisions. They also meet policy officers' needs for evidence to be provided in a way that can directly inform their decision-making processes. © 2009 Elsevier Ireland Ltd. All rights reserved.

- Description: Organised sports are a popular form of physical activity, but unfortunately, participation can result in injury. Despite this, there have been surprisingly few studies that have reported the population rate of sports injury. Data from the 2005 New South Wales (NSW, Australia) Population Health Survey were analysed to describe self-reported injury experiences during participation in organised sports activities and the source of treatment for such injuries during a 12-month period in a population representative sample of adults aged 16+ years. At interview, 2414 respondents stated that they had participated in organised sport in the previous 12 months and just under one-third (30.9%) reported that they had been injured during this participation. Half of all injuries required formal treatment from a health or medical practitioner. Physiotherapists most commonly provided treatment for sports injury (26.6% of cases) followed by general practitioners (15.6%). Only 2.8% of all injured sports participants were admitted to hospital for their injury and a further 6.1% received treatment in an emergency department. This corresponds to at most only 8.9% of all treated sports injuries receiving treatment in a hospital setting. Population-based estimates of the rate and burden of sports injuries that rely solely on routine hospital data collections are likely to grossly underestimate the size of the problem, as very few cases are treated in a hospital setting. © 2009 Sports Medicine Australia.

- Description: Falls and their injury outcomes have count distributions that are highly skewed toward the right with clumping at zero, posing analytical challenges. Different modelling approaches have been used in the published literature to describe falls count distributions, often without consideration of the underlying statistical and modelling assumptions. This paper compares the use of modified Poisson and negative binomial (NB) models as alternatives to Poisson (P) regression, for the analysis of fall outcome counts. Four different count-based regression models (P, NB, zero-inflated Poisson (ZIP), zero-inflated negative binomial (ZINB)) were each individually fitted to four separate fall count datasets from Australia, New Zealand and United States. The finite mixtures of P and NB regression models were also compared to the standard NB model. Both analytical (F, Vuong and bootstrap tests) and graphical approaches were used to select and compare models. Simulation studies assessed the size and power of each model fit. This study confirms that falls count distributions are over-dispersed, but not dispersed due to excess zero counts or heterogeneous population. Accordingly, the P model generally provided the poorest fit to all datasets. The fit improved significantly with NB and both zero-inflated models. The fit was also improved with the NB model, compared to finite mixtures of both P and NB regression models. Although there was little difference in fit between NB and ZINB models, in the interests of parsimony it is recommended that future studies involving modelling of falls count data routinely use the NB models in preference to the P or ZINB or finite mixture distribution. The fact that these conclusions apply across four separate datasets from four different samples of older people participating in studies of different methodology, adds strength to this general guiding principle. © 2009 Elsevier Ltd.
