Trends and Patterns in Unintentional Injury Fatalities in Australian Agriculture.

Agriculture is recognized internationally as a hazardous industry. This article describes the trends and patterns of unintentional farm fatalities in Australia. Data from the National Coronial Information System were analyzed to assess all unintentional farm fatalities for the 2001-2015 period. A secondary comparison with earlier coronial system data from 1989-1992 was also completed to ascertain historical changes. There was no statistically significant change in the rate of work-related fatalities per 100,000 workers in the 2001-2015 period. However, there was a significant curvilinear reduction in all cases of fatality (work and non-work related) per 10,000 agricultural establishments, which decreased from 2001 to 2009-2011 and then increased to 2015. The longer-term data from 1989-2015 revealed a reduction of 30% in work-related cases per 100,000 workers and a reduction of 35% in all cases (work and non-work) per 10,000 agricultural establishments. For both work-related and all cases, there was a statistically significant reduction from 1989 to 2005 and then no change thereafter. The longer-term reduction in farm fatalities ceased in the mid-2000s, and the rate has remained stable since. Fatal injuries continue to impose a significant burden on Australian farming communities, with the rate remaining relatively static for the past ten years. New evidence-based interventions targeting priority areas are required to reduce the incidence of fatalities in Australia agriculture.

Fatal Incidents in Australia's Older Farmers (2001-2015).

OBJECTIVES: This study assesses nonintentional injury deaths of older farmers and the causal agents associated with these fatalities in Australia (2001-2015). It also explores approaches based on the hierarchy of risk controls to reduce fatalities and injuries in this cohort. METHODS: Data on farm-related incidents were sourced from the National Coroners Information System (NCIS) for the study period and coded. Rates were calculated and regression analyses completed to assess trends over time. RESULTS: Those in the 50+ years category (n = 610) accounted for 49.8% of all on-farm nonintentional injury deaths, with males (n = 566) dominating the cases. The annual mean was 40.66 cases (SD = 8.08) and the average rate 36/100,000. Trend analysis revealed a nonstatistically significant (P < 0.05) increase in cases over the period. Farm vehicles and machinery were responsible for almost two thirds of the fatal cases. CONCLUSION: Nonintentional fatality rates for older farmers have remained relatively unchanged for a significant period in Australia. There is a need to examine additional approaches that not only maintain the benefits of work activity for older farmers but also balance this against a safety perspective.

Non-intentional farm injury fatalities in NSW, Australia, 2001-2015.

BACKGROUND: Agriculture is one of the most hazardous industries in Australia. The Australian Centre for Agricultural Health and Safety is the only agency that records all non-intentional injury-related events (work and nonwork) on Australian farms. MATERIALS AND METHODS: Drawing on records from the National Coronial Information System, data for New South Wales (NSW), Australia, were analysed to assess cases in the 2001-2015 period. Each case was reviewed in accordance with the Farm Injury Optimal Dataset to ascertain gender, age, work relatedness and causal agents. The location of each incident was also mapped by Statistical Area Level 4. Denominator data on the number of agricultural establishments in each area and the number of workers involved in agriculture across all of NSW were sourced from the Australian Bureau of Statistics (ABS). Two-piece linear regressions using 2007 as the change point were completed to ascertain trends for the work-related cases and all deaths (work and nonwork). Differences in rates of all deaths by regions were assessed using Poisson regression models. RESULTS: Results indicate no change in the rate of work-related deaths per 100 000 workers over the 15-year period (mean 17.3). Although there was a statistically significant reduction in all deaths (work and nonwork) per 10 000 farms through to 2007, the rate has remained stable since this time. There was no significant variation in the all-deaths rate (work and nonwork) between any of the geographic areas. Study limitations included estimations based on ABS data for the distribution of farms, the lack of data by statistical area on agricultural worker numbers and a case closure rate of 87%. LESSONS LEARNT: There has been no improvement in work-related fatality rates in the sector in NSW for at least 15 years, and similarly no improvement in the all-injury fatality rate (work and nonwork) since 2007. Data in this study can be used to strengthen investment and revitalise the adoption of evidence based approaches that address relevant issues.

Effectiveness of a multifactorial intervention on preventing development of frailty in pre-frail older people: study protocol for a randomised controlled trial.

INTRODUCTION: Frailty is a major concern due to its costly and widespread consequences, yet evidence of effective interventions to delay or reduce frailty is lacking. Our previous study found that a multifactorial intervention was feasible and effective in reducing frailty in older people who were already frail. Identifying and treating people in the pre-frail state may be an effective means to prevent or delay frailty. This study describes a randomised controlled trial that aims to evaluate the effectiveness of a multifactorial intervention on development of frailty in older people who are pre-frail. METHODS AND ANALYSIS: A single centre randomised controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. Two hundred and thirty people aged above 70 who meet the Cardiovascular Health Study frailty criteria for pre-frailty, reside in the community and are without severe cognitive impairment will be recruited. Participants will be randomised to receive a multifactorial intervention or usual care. The intervention group will receive a 12-month interdisciplinary intervention targeting identified characteristics of frailty and problems identified during geriatric assessment. Participants will be followed for a 12-month period. Primary outcome measures will be degree of frailty measured by the number of Cardiovascular Health Study frailty criteria present, and mobility measured with the Short Physical Performance Battery. Secondary outcomes will include measures of mobility, mood and use of health and community services. ETHICS AND DISSEMINATION: The study was approved by the Northern Sydney Local Health District Health Research Ethics Committee (1207-213M). The findings will be disseminated through scientific and professional conferences, and in peer-reviewed journals.

Economic evaluation of a multifactorial, interdisciplinary intervention versus usual care to reduce frailty in frail older people.

OBJECTIVE: To compare the costs and cost-effectiveness of a multifactorial interdisciplinary intervention versus usual care for older people who are frail. DESIGN: Cost-effectiveness study embedded within a randomized controlled trial. SETTING: Community-based intervention in Sydney, Australia. PARTICIPANTS: A total of 241 community-dwelling people 70 years or older who met the Cardiovascular Health Study criteria for frailty. INTERVENTION: A 12-month multifactorial, interdisciplinary intervention targeting identified frailty characteristics versus usual care. MEASUREMENTS: Health and social service use, frailty, and health-related quality of life (EQ-5D) were measured over the 12-month intervention period. The difference between the mean cost per person for 12 months in the intervention and control groups (incremental cost) and the ratio between incremental cost and effectiveness were calculated. RESULTS: A total of 216 participants (90%) completed the study. The prevalence of frailty was 14.7% lower in the intervention group compared with the control group at 12 months (95% CI 2.4%-27.0%; P = .02). There was no significant between-group difference in EQ-5D utility scores. The cost for 1 extra person to transition out of frailty was $A15,955 (at 2011 prices). In the "very frail" subgroup (participants met >3 Cardiovascular Health Study frailty criteria), the intervention was both more effective and less costly than the control. A cost-effectiveness acceptability curve shows that the intervention would be cost-effective with 80% certainty if decision makers were willing to pay $A50,000 per extra person transitioning from frailty. In the very frail subpopulation, this reduced to $25,000. CONCLUSION: For frail older people residing in the community, a 12-month multifactorial intervention provided better value for money than usual care, particularly for the very frail, in whom it has a high probability of being cost saving, as well as effective.

Effect of a multifactorial, interdisciplinary intervention on risk factors for falls and fall rate in frail older people: a randomised controlled trial.

BACKGROUND: frail older people have a high risk of falling. OBJECTIVE: assess the effect of a frailty intervention on risk factors for falls and fall rates in frail older people. DESIGN: randomised controlled trial. PARTICIPANTS: 241 community-dwelling people aged 70+ without severe cognitive impairment who met the Cardiovascular Health Study frailty definition. INTERVENTION: multifactorial, interdisciplinary intervention targeting frailty characteristics with an individualised home exercise programme prescribed in 10 home visits from a physiotherapist and interdisciplinary management of medical, psychological and social problems. MEASUREMENTS: risk factors for falls were measured using the Physiological Profile Assessment (PPA) and mobility measures at 12 months by a blinded assessor. Falls were monitored with calendars. RESULTS: participants had a mean (SD) age of 83.3 (5.9) years, 68% were women and 216 (90%) completed the study. After 12 months the intervention group had significantly better performance than the control group, after controlling for baseline values, in the PPA components of quadriceps strength (between-group difference 1.84 kg, 95% CI 0.17-3.51, P = 0.03) and body sway (-90.63 mm, 95% CI -168.6 to -12.6, P = 0.02), short physical performance battery (1.58, 95% CI 1.02-2.14, P ≤ 0.001) and 4 m walk (0.06 m/s 95% CI 0.01-0.10, P = 0.02) with a trend toward a better total PPA score (-0.40, 95% CI -0.83-0.04, P = 0.07) but no difference in fall rates (incidence rate ratio 1.12, 95% CI 0.78-1.63, P = 0.53). CONCLUSION: the intervention improved performance on risk factors for falls but did not reduce the rate of falls. TRIAL REGISTRATION: ACTRN12608000250336.

A multifactorial interdisciplinary intervention reduces frailty in older people: randomized trial.

BACKGROUND: Frailty is a well known and accepted term to clinicians working with older people. The study aim was to determine whether an intervention could reduce frailty and improve mobility. METHODS: We conducted a single center, randomized, controlled trial among older people who were frail in Sydney, Australia. One group received an intervention targeting the identified characteristics of frailty, whereas the comparison group received the usual health care and support services. Outcomes were assessed by raters masked to treatment allocation at 3 and 12 months after study entry. The primary outcomes were frailty as assessed by the Cardiovascular Health Study criteria, and mobility as assessed by the Short Physical Performance Battery. Secondary outcome measures included disability, depressive symptoms and health-related quality of life. RESULTS: A total of 216 participants (90%) completed the study. Overall, 68% of participants were women and the mean age was 83.3 years (standard deviation, 5.9). In the intention-to-treat analysis, the between-group difference in frailty was 14.7% at 12 months (95% confidence interval: 2.4%, 27.0%; P = 0.02). The score on the Short Physical Performance Battery, in which higher scores indicate better physical status, was stable in the intervention group and had declined in the control group; with the mean difference between groups being 1.44 (95% confidence interval, 0.80, 2.07; P <0.001) at 12 months. There were no major differences between the groups with respect to secondary outcomes. The few adverse events that occurred were exercise-associated musculoskeletal symptoms. CONCLUSIONS: Frailty and mobility disability can be successfully treated using an interdisciplinary multifaceted treatment program.

Treating frailty--a practical guide.

Frailty is a common syndrome that is associated with vulnerability to poor health outcomes. Frail older people have increased risk of morbidity, institutionalization and death, resulting in burden to individuals, their families, health care services and society. Assessment and treatment of the frail individual provide many challenges to clinicians working with older people. Despite frailty being increasingly recognized in the literature, there is a paucity of direct evidence to guide interventions to reduce frailty. In this paper we review methods for identification of frailty in the clinical setting, propose a model for assessment of the frail older person and summarize the current best evidence for treating the frail older person. We provide an evidence-based framework that can be used to guide the diagnosis, assessment and treatment of frail older people.

Frailty Intervention Trial (FIT).

BACKGROUND: Frailty is a term commonly used to describe the condition of an older person who has chronic health problems, has lost functional abilities and is likely to deteriorate further. However, despite its common use, only a small number of studies have attempted to define the syndrome of frailty and measure its prevalence. The criteria Fried and colleagues used to define the frailty syndrome will be used in this study (i.e. weight loss, fatigue, decreased grip strength, slow gait speed, and low physical activity). Previous studies have shown that clinical outcomes for frail older people can be improved using multi-factorial interventions such as comprehensive geriatric assessment, and single interventions such as exercise programs or nutritional supplementation, but no interventions have been developed to specifically reverse the syndrome of frailty.We have developed a multidisciplinary intervention that specifically targets frailty as defined by Fried et al. We aim to establish the effects of this intervention on frailty, mobility, hospitalisation and institutionalisation in frail older people. METHODS AND DESIGN: A single centre randomised controlled trial comparing a multidisciplinary intervention with usual care. The intervention will target identified characteristics of frailty, functional limitations, nutritional status, falls risk, psychological issues and management of chronic health conditions. Two hundred and thirty people aged 70 and over who meet the Fried definition of frailty will be recruited from clients of the aged care service of a metropolitan hospital. Participants will be followed for a 12-month period. DISCUSSION: This research is an important step in the examination of specifically targeted frailty interventions. This project will assess whether an intervention specifically targeting frailty can be implemented, and whether it is effective when compared to usual care. If successful, the study will establish a new approach to the treatment of older people at risk of further functional decline and institutionalisation. The strategies to be examined are readily transferable to routine clinical practice and are applicable broadly in the setting of aged care health services.
