A comprehensive list of asthmagens to inform health interventions in the Australian workplace

Objective: To develop a comprehensive list of asthmagens which may occur in occupational settings in Australia. Methods: Potential asthmagens considered for this list were identified through work health and safety classification databases in Australia and through lists developed by professional associations in other countries. Inclusion criteria were: there is evidence that the agent is asthmagenic; it is used in occupational settings; and it is available in Australia. Results: The final list contained 277 asthmagens in 27 groups that may be found in occupational circumstances in Australia. Three other agents that have been documented as asthmagens in Australia were included: almond dust, fluoride (in aluminium pot room fumes); and sawdust from the Australian Blackwood. Conclusions: This is the first comprehensive and inclusive list of Australian occupationally relevant asthmagens to have been compiled. Implications: This list is specific for Australian workplace exposure to asthmagens. It will help focus policy and preventative practices and reduce the burden of occupational asthma. It will also be useful in future studies to identify those who are exposed to the asthmagens and provide information to assist regulators to identify industries, occupations, specific activities and existing exposure standards that can be targeted to improve worker health and welfare

Construction accident causality: learning from different countries and differing consequences

This is an Accepted Manuscript of an article published in Construction Management and Economics on 20 May 2014, available online: http://www.tandfonline.com/10.1080/01446193.2014.907498Fundamental questions remain about the practical value and generalizability of accident causation frameworks for explaining construction accidents. Relevant causality literature is reviewed; three research projects compared and implications of accident causation theories for accident investigation and analysis discussed, particularly for accidents with differing consequences and in different national contexts. The effectiveness of the UK accident causality framework ConAC (Construction Accident Causality) in identifying occupational accident causes in different industry contexts (Australia and the USA) is evaluated; and the implications of the choice of theoretical framework in the analysis of construction accident causation considered. The ConAC framework was developed from a real-time analysis of 100 relatively minor construction accidents. The Australian study used this framework to analyse the National Coroners reports of 258 construction fatalities and the USA study used it to develop research instruments for interviews regarding 27 construction accidents of varying consequences. The results suggest that the ConAC framework is helpful for the analysis of the causes of accidents with outcomes of differing severity. The studies also suggest that it has international applicability despite differing occupational health and safety legislative contexts and industrial arrangements. Furthermore, significant learning can be obtained from considering underlying causes of accidents

Estimated prevalence of exposure to occupational carcinogens in Australia (2011-2012)

Background and objectives: Although past studies of workplace exposures have contributed greatly to our understanding of carcinogens, significant knowledge gaps still exist with regard to the actual extent of exposure among current workers, with no routinely collected population-based data being available in most countries. This study, the Australian Work Exposures Study (AWES), aimed to investigate the current prevalence of occupational exposure to carcinogens. Methods: A random sample of men and women aged between 18 and 65, who were currently in paid employment, were invited to participate in a telephone interview collecting information about their current job and various demographic factors. Interviews were conducted using a web-based application (OccIDEAS). OccIDEAS uses the expert exposure method in which participants are asked about their job tasks and predefined algorithms are used to automatically assign exposures. Responses were obtained from 5023 eligible Australian residents, resulting in an overall response rate of 53%. Results: 1879 respondents (37.6%) were assessed as being exposed to at least one occupational carcinogen in their current job. Extrapolation of these figures to the Australian working population suggested 3.6 million (40.3%) current workers could be exposed to carcinogens in their workplace. Exposure prevalence was highest among farmers, drivers, miners and transport workers, as well as men and those residing in regional areas. Conclusions: This study demonstrates a practical, web-based approach to collecting population information on occupational exposure to carcinogens and documents the high prevalence of current exposure to occupational carcinogens in the general population

Designing safer working interventions through a literature review using a mechanisms-based approach

The explanation for what safety interventions work in any particular circumstance remains elusive, resulting in many work-related fatalities and injuries every year. We propose a shift in perspective from a preoccupation with safety interventions and their effects to an elucidation of the generative mechanisms underpinning safety and its contiguous context. Using an analytical framework based on contexts, interventions, mechanisms and outcomes (CIMO) we were able to review 43 empirical studies of safety interventions deployed by leaders in organizations. This motivated the development of 10 design propositions; 5 related to accident and injury reduction and 5 to changing safety behaviours. Greater understanding of the mechanisms by which interventions exert their effects will lead to the design of more context appropriate safety interventions thereby enhancing individual and organizational safety in the future and the development of evidence-based safety

The reliability of information on work-related injuries available from hospitalisation data in Australia

Objective: To examine the reliability of work-related activity coding for injury-related hospitalisations in Australia. Method: A random sample of 4373 injury-related hospital separations from 1 July 2002 to 30 June 2004 were obtained from a stratified random sample of 50 hospitals across 4 states in Australia. From this sample, cases were identified as work-related if they contained an ICD-10-AM work-related activity code (U73) allocated by either: (i) the original coder; (ii) an independent auditor, blinded to the original code; or (iii) a research assistant, blinded to both the original and auditor codes, who reviewed narrative text extracted from the medical record. The concordance of activity coding and number of cases identified as work-related using each method were compared. Results: Of the 4373 cases sampled, 318 cases were identified as being work-related using any of the three methods for identification. The original coder identified 217 and the auditor identified 266 work-related cases (68.2% and 83.6% of the total cases identified, respectively). Around 10% of cases were only identified through the text description review. The original coder and auditor agreed on the assignment of work-relatedness for 68.9% of cases. Conclusions and Implications: The current best estimates of the frequency of hospital admissions for occupational injury underestimate the burden by around 32%. This is a substantial underestimate that has major implications for public policy, and highlights the need for further work on improving the quality and completeness of routine, administrative data sources for a more complete identification of work-related injuries
