The incidence and burden of hospital-treated sports-related injury in people aged 15+ years in Victoria, Australia, 2004-2010 : A future epidemic of osteoarthritis?

Objectives: Previous sports injury is a known risk factor for subsequent osteoarthritis (OA), but population-based rates of sports injury are unknown. The aims of this study were to: (1) describe the trends in the population incidence and burden of all hospital-treated sports injury in Victoria, Australia in adults aged 15+ years; (2) determine the incidence of lower limb and knee injuries; and (3) quantify their population health burden as average direct hospital costs per injury and lengths of stay. Methods: Health sector data relating to adults aged 15+ years, for 2004-2010 inclusive, was extracted from the Victorian Admitted Episodes Dataset (VAED) and Victorian Emergency Minimum Dataset (VEMD). Data relating to sports injuries were identified using activity codes in each dataset Trends in injury frequency and rates were determined, and economic burden was calculated. Results: The overall annual rate of hospital treated sports injuries increased by 24% (P = 0.001), and lower limb injuries by 26% (P = 0.001) over the 7 years. The associated accumulated economic burden was $265 million for all sports injuries and$110 million for lower limb injuries over the 7-years. Conclusions: The findings of this study show a significant increase in sports injuries in the state of Victoria, Australia over a 7-year period. As previous sports injury is a risk factor for the development of OA, the future incidence of OA will escalate, placing an even greater burden on health care systems. Population-wide preventative strategies that reduce the risk of sports injury are urgently required in order to reduce the future burden of OA. © 2015 Osteoarthritis Research Society International

Time to add a new priority target for child injury prevention? The case for an excess burden associated with sport and exercise injury: population-based study

OBJECTIVE: To determine the population-level burden of sports injuries compared with that for road traffic injury for children aged <15 years in Victoria, Australia. DESIGN: Retrospective observational study. SETTING: Analysis of routinely collected data relating to non-fatal hospital-treated sports injury and road traffic injury cases for children aged <15 years in Victoria, Australia, over 2004-2010, inclusive. PARTICIPANTS: 75 413 non-fatal hospital-treated sports injury and road traffic injury cases in children aged <15 years. Data included: all Victorian public and private hospital hospitalisations, using the International Statistical Classification of Diseases and Health Related Problems, 10th Revision, Australian Modification (ICD-10-AM) activity codes to identify sports-related cases and ICD-10-AM cause and location codes to identify road traffic injuries; and injury presentations to 38 Victorian public hospital emergency departments, using a combination of activity, cause and location codes. MAIN OUTCOME MEASURES: Trends in injury frequency and rate were analysed by log-linear Poisson regression and the population-level injury burden was assessed in terms of years lived with disability (YLD), hospital bed-days and direct hospital costs. RESULTS: Over the 7-year period, the annual frequency of non-fatal hospital-treated sports injury increased significantly by 29% (from N=7405 to N=9923; p<0.001) but the frequency of non-fatal hospital-treated road traffic injury decreased by 26% (from N=1841 to N=1334; p<0.001). Sports injury accounted for a larger population health burden than did road traffic injury on all measures: 3-fold the number of YLDs (7324.8 vs 2453.9); 1.9-fold the number of bed-days (26 233 vs 13 886) and 2.6-fold the direct hospital costs ($A5.9 millions vs$A2.2 millions). CONCLUSIONS: The significant 7-year increase in the frequency of hospital-treated sports injury and the substantially higher injury population-health burden (direct hospital costs, bed-day usage and YLD impacts) for sports injury compared with road traffic injury for children aged <15 years indicates an urgent need to prioritise sports injury prevention in this age group

Suicide among those who use mental health services: Suicide risk factors as evidenced from contact-based characteristics in Victoria

ObjectiveThe majority of suicide decedents have had contact with health services in the months before their death. Contacts for mental health services present potential suicide prevention opportunities. This study aims to compare contact-based characteristics among suicide decedents and living controls in the year subsequent to clinical mental health contact with the public health system in Victoria, Australia.MethodsA population-based nested case-control study of those who had mental health-related hospital and community contacts with the public health system was conducted. Cases (suicide decedents) were age and gender-matched to living controls (suicide non-decedents). These records were linked to records of suicides that occurred in the 12 months following the health service contact, between January 1, 2011, and December 31, 2016. Victorian residents aged 10 years and above were selected at the time of contact (483,933 clients). In the study population, conditional logistic regression models were used to assess the relationship between contact-based characteristics and suicide. Socio-demographics and mental health-related hospital and community contact data was retrieved from the Victorian Admitted Episodes Dataset, the Victorian Emergency Minimum Dataset and the Public Clinical Mental Health database and suicide data from the Victorian Suicide Register.ResultsDuring a six-year period, 1,091 suicide decedents had at least one mental health contact with the public health system in the 12 months preceding the suicide. Overall, controls used more mental health services than cases; however, cases used more mental health services near the event. The relationship between the type of service and suicide differed by service type: hospital admissions and emergency department presentations had a significant positive association with suicide with an OR of 2.09 (95% CI 1.82–2.40) and OR of 1.13 (95% CI 1.05–1.22), and the effect size increased as the event approached, whereas community contacts had a significant negative association with an OR of 0.93 (95% CI 0.92–0.94), this negative association diminished in magnitude as the event approached (OR∼1).ConclusionSuicide decedents had less contact with mental health services than non-decedents; however, evidence suggests suicide decedents reach out to mental health services proximal to suicide. An increase in mental health service contact by an individual could be an indication of suicide risk and therefore an opportunity for intervention. Further, community level contact should be further explored as a possible prevention mechanism considering the majority of suicide decedents do not access the public clinical mental health services

Cost-effectiveness of installing barriers at bridge and cliff sites for suicide prevention in Australia

Importance: Installation of barriers has been shown to reduce suicides. To our knowledge, no studies have evaluated the cost-effectiveness of installing barriers at multiple bridge and cliff sites where suicides are known to occur. Objective: To examine the cost-effectiveness of installing barriers at bridge and cliff sites throughout Australia. Design, Setting, and Participants: This economic evaluation used an economic model to examine the costs, costs saved, and reductions in suicides if barriers were installed across identified bridge and cliff sites over 5 and 10 years. Specific and accessible bridge and cliff sites across Australia that reported 2 or more suicides over a 5-year period were identified for analysis. A partial societal perspective (including intervention costs and monetary value associated with preventing suicide deaths) was adopted in the development of the model. Interventions: Barriers installed at bridge and cliff sites. Main Outcomes and Measures: Primary outcome was return on investment (ROI) comparing cost savings with intervention costs. Secondary outcomes included incremental cost-effectiveness ratio (ICER), comprising the difference in costs between installation of barriers and no installation of barriers divided by the difference in reduction of suicide cases. Uncertainty and sensitivity analyses were undertaken to examine the association of changes in suicide rates with barrier installation, adjustments to the value of statistical life, and changes in maintenance costs of barriers. Results: A total of 7 bridges and 19 cliff sites were included in the model. If barriers were installed at bridge sites, an estimated US $145 million (95$90 to $160 million) could be saved in prevented suicides over 5 years, and US$270 million (95% UI, $176 to$298 million) over 10 years. The estimated ROI ratio for building barriers over 10 years at bridges was 2.4 (95% UI, 1.5 to 2.7); the results for cliff sites were not significant (ROI, 2.0; 95% UI, -1.1 to 3.8). The ICER indicated monetary savings due to averted suicides over the intervention cost for bridges, although evidence for similar savings was not significant for cliffs. Results were robust in all sensitivity analyses except when the value of statistical life-year over 5 or 10 years only was used. Conclusions and Relevance: In an economic analysis, barriers were a cost-effective suicide prevention intervention at bridge sites. Further research is required for cliff sites

The burden of fall-related injury among older persons in New South Wales

OBJECTIVE: To develop a comprehensive estimate of the burden of fall-related injury among older people in New South Wales. METHODS: Fall injuries in 2006/07 were estimated using information from several datasets and the literature. Healthcare costs were calculated using Australia-Refined--Diagnostic-Related Group costs for hospital episodes of care and average costs for Emergency Department presentations, ambulance transport and residential aged care (RAC). Ratios of the cost of inpatient care relative to other health services, derived from the literature, were used to estimate the costs associated with these services. RESULTS: In 2006/07, in NSW, there were almost 143,000 falls, among older people, resulting in injuries requiring medical treatment. The total cost of healthcare associated with these falls was estimated at $558.5 million. Although accounting for only 6% of the NSW population aged 65 years and older, persons in RAC accounted for 15% of the total cost of falls injury and 21% of hospital inpatient costs. CONCLUSION AND IMPLICATIONS: This study demonstrates the extremely high economic cost of falls in older persons and highlights the disproportionate impact of falls in RAC. The study underscores the urgent need for significant investment in fall-injury prevention efforts in both the community and RAC settings.6 page(s

Hospital-treated snow sport injury in Victoria, Australia : A summary of 2003–2012

Introduction: To determine the incidence rate and changes over time for ice and snow sports injury in Victoria, Australia, from 2003 to 2012 and describe the most common types and causes of these injuries. Methods: Retrospective data from the Victorian Injury Surveillance Unit describing hospital admissions and emergency department presentations were extracted for the 10-year period of 2003 to 2012 for all ice- and snow-related injury. Descriptive injury data and participation-adjusted trend analyses using log-linear regression modelling of data (statistical significance, P<0.05) from the Exercise, Recreation and Sport Survey 2003 to 2010 are presented. Results: Overall, there were 7387 ice- and snow-related injuries, with a significant increase in hospital-treated snowboard injuries and a (nonsignificant) decline in hospital-treated ski injuries over the 10 years. Skiing (39%) and snowboarding (37%) had the highest incidence of hospital-treated injury, with males aged 15 to 24 years injured most frequently in both sports. Falls were the most common cause of injury in both skiing (68%) and snowboarding (78%). Conclusions: Patterns of snow sports injury in Australia during 2003 to 2012 remain similar to findings of national studies conducted decades earlier. More importantly, however, Australian injury patterns are comparable to international statistics and thus may be generalizable internationally. Head injuries, although infrequent, are associated with great injury severity due to a high frequency of hospitalization. Furthermore, research into the use of personal protective equipment and other injury prevention measures among Australian participants, particularly by young, male snowboarders, is required. Given the similar injury patterns, injury prevention measures implemented internationally could reasonably translate to an Australian setting

Increasing incidence of hospitalisation for sport-related concussion in Victoria, Australia

Objective: To describe trends in hospitalisation for sport-related concussion. Design, setting and patients: Analysis of routinely collected hospital admissions data from all Victorian hospitals (public and private) over the 2002-03 to 2010-11 financial years for patients aged ≥15 years with a diagnosis of concussion and an ICD-10-AM external cause activity code indicating sport. Main outcome measures: Number and cost of hospitalisations; rate of hospitalisation per 100000 participants overall and for specific sports; and percentage change in frequency and hospitalisation rate per 100000 participants over 9 years. Results: There were 4745 hospitalisations of people aged ≥15 years for sport-related concussion, with a total hospital treatment cost of $17944799. The frequency of hospitalisation increased by 60.5% (95% CI, 41.7%-77.3%) over the 9 years, but could only partially be explained by increases in sports participation, as the rate per 100000 participants also increased significantly, by 38.9% (95% CI, 17.5%-61.7%). After adjustment for participation, rates were highest for motor sports, equestrian activities, Australian football, rugby and roller sports. The greatest significant increases in rates were seen in roller sports, rugby, soccer and cycling. Conclusions: The frequency and participation-adjusted rate of hospitalisation for sport-related concussion, both overall and across several sports, increased significantly over the 9 years. These findings, along with high levels of public concern, make prevention of head injury in sport a population health priority in Australia
