A systematic review of literature on occupational health and safety interventions for older workers.

As the global population ages there is an imperative to enhance labour participation of older workers in ways that support good physical and psychological health. However, there is limited guidance for organisations on how to do this effectively. This systematic review examined literature identified through four databases and a targeted web-search, yielding 39 PRISMA records (32 scholarly, seven grey literature) reporting workplace interventions aimed at improving the injury outcomes of older workers. The review revealed that organisational and composite interventions may be most effective, although an absence of robust research in this area and a scarcity of empirical evidence-based interventions known to improve injury outcomes for older workers was noted. Responding to these shortcomings, this article presents 'A future research agenda for older worker health, safety and well-being interventions.' This systems-based approach has a dual focus on organisational and composite interventions combined with robust research design.Practitioner summary: We conducted a systematic literature review of studies focussed on workplace interventions to improve the physical and psychological safety of older workers. Within the existing literature, evidence for effective interventions and guidance for organisations is weak. We present a future research agenda with a systems approach to address these gaps.

Impact of Public Seating Design on Mobility and Independence of Older Adults.

Background:Mobility and independence of older adults are influenced by age-related capabilities and limitations, as well as environmental factors such as non-optimum design of public seating (e.g., inappropriate seat height, angle, and compressibility as well as armrests). This study was the first part of a multi-stage investigation of the impact of public seating on older adults. Method:One hundred and six older adults (aged 65 and over) completed an online survey regarding difficulties experienced with standing up from public seating (e.g. frequency; location; type of seating; effects). Results:A majority (59.4%) reported experiencing problems, with seat height the most common issue. Shopping malls, cafes and restaurants, doctor's offices, outdoor locations, and public toilets were the most common locations. Effects included inconvenience, embarrassment, discomfort, pain, and needing help from another person to stand. Discussion:Further research is needed to explore the locations and features of seating that can contribute to this problem.

Optimizing aged care environments to promote resident functional mobility and reduce staff injury risk.

Introduction: This study aimed to evaluate the suitability and usability of the Pro-Mobility patient/person handling assessment tool (ProMob) within residential aged care. Physiological changes associated with ageing influence an older person's ability to perform functional mobility tasks such as transferring from furniture and walking. Strategies that improve capability and/or reduce the physical demands of the task have the potential to promote an older person's mobility, independence and wellbeing. Environment-related strategies in Manual Handling of People (MHP), such as optimum seated heights, in part address this challenge, as they can promote resident functional mobility while also protecting staff from injury. The ProMob tool was developed to address this issue through systematic evaluation of these environmental factors. Methods: The participants in this study were seven (7) residential aged care facilities (RACFs) operated by a not-for-profit aged care organization. A qualified assessor evaluated MHP risk management with the ProMob tool at each RACF through collection of data for a random sample of residents (n = 67) regarding their living environments and available mobility information. Data was transferred to an SPSS-22 statistical software database for analysis which involved descriptive statistics and cross tabulations. Results: Application of the ProMob tool provided effective quantification of the nature and extent of environment-related MHP interventions that may influence resident mobility. Areas for improvement with MHP risk management were identified, with variation evident across RACF's within the same organisation, which was not consistent with levels of care (e.g., lack of clear space to facilitate mobility). Low level care facilities were observed to have fewer adaptive environmental features that could potentially slow decline in independence. Discussion: Features of the aged care environment can be used to facilitate the functional mobility of aged care residents, and simultaneously reduce injury risk for staff in MHP interactions. The ProMob tool can be used for auditing care facilities, planning re-development, and continual improvement in provision of care and management of staff injury risk exposure.

A systems model for the design of occupational health and safety management systems inclusive of work-from-home arrangements.

The study addressed an important knowledge gap in the literature by co-designing a model for OHS management systems inclusive of workers who work-from-home, with a focus on psychosocial risks. This qualitative research study utilised a series of co-design focus groups involving Australian regulators, health and safety managers and practitioners, senior managers, middle managers and workers who work-from-home, to better understand the types of measures that organisations can apply to improve their health and safety management systems. Using a systems approach, consideration was given to the organisation of the remote working system, the home-work interface for remote workers, the competencies of managers and employees in regard to their occupation health and safety (OHS) responsibilities, and the complexity of identifying, reporting and monitoring psychosocial hazards for employees working from home. The study identified a need for tools designed to support both managers and workers in promoting psychologically safe working from home.

Older Worker-Orientated Human Resource Practices, Wellbeing and Leave Intentions: A Conservation of Resources Approach for Ageing Workforces.

At a time where there are ageing populations, global shortages of skilled labour, and migration pathways impacted by the COVID-19 pandemic, retaining older workers presents as a vital strategic initiative for organizations globally. This study examines the role of Human Resource Practices (HRPs), which are oriented towards accommodating the needs of an ageing workforce in mitigating psychological distress and turnover intentions. The study collected self-reported survey data from 300 Australian employees over the age of 45, over two time points. Using structural equation modelling, the study analyzed the extent to which Older Worker-oriented Human Resources Practices (OW-HRPs) translate into employee psychological health and retention within organizations, through the mediation of ageism and work-life conflict. The results support our hypothesis that OW-HRPs are associated with lower ageism, better work-life balance; and in combination these reduce psychological distress and help retain older workers in the workforce. We conclude that OW-HRPs can foster work environments conducive to older worker wellbeing, supporting the retention of talent and maintaining effectiveness, in the face of substantial labour supply challenges brought on by the COVID-19 pandemic and an ageing population.

Relative risk perception for terrorism: implications for preparedness and risk communication.

Terrorism presents a significant risk that is often approached at public policy, infrastructure, or emergency management level. Public perceptions of the likelihood of terrorist events, and how this may relate to individual preparedness, are not always extensively examined. The tendency to think that negative events are less likely to happen to oneself than to the average person is known as optimism bias. Optimism bias is relevant to perceptions of terrorism, because it is thought to be related to a reduction in precaution use. Using an online survey of 164 participants, this study aimed to determine whether Sydney residents thought they had a lower likelihood of experiencing terrorist events than other Australians. Significant optimism bias was observed for witnessing terrorist events, but not for personally experiencing terrorist events. In addition, Sydney residents tended to think that terrorist attacks were more likely to occur in Sydney than another major Australian city in the next five years. At the same time, household and workplace preparedness for terrorism was quite low, as was awareness of emergency strategies in the central business district. Perceptions of high likelihood of terrorism happening in one's own city, yet low preparedness present a challenge for risk communication and emergency management strategies. The diversity of possible terrorist targets, and the simple plans that can moderate the effects of a disaster may need to be emphasized in future anti-terrorism initiatives.

Musculoskeletal disorders in aged care workers: a systematic review of contributing factors and interventions.

BACKGROUND: There is limited evidence on contributing factors and effective interventions for musculoskeletal injuries in aged care workers. PURPOSE: To systematically review the factors that contribute to musculoskeletal disorder risk amongst workers in the aged care industry, and to undertake a qualitative comparison of the interventions designed and implemented to prevent injury within this workforce. METHODS: A systematic review of the literature was conducted in Web of Science, Scopus, ProQuest, Medline, and PubMed. Relevant grey literature was also examined. Articles that reported factors that contribute to musculoskeletal injuries, or interventions to prevent and manage musculoskeletal injuries in residential aged care workers were included. FINDINGS: Of the 864 articles and 35 grey literature publications found, 63 and 29 were included in the review respectively. Results indicate that physical factors such as manual handling of people, use of assistive devices, and physical work environment are most commonly associated with musculoskeletal disorders in this population. Limited evidence of organisational and psychosocial factors considered staffing issues, work schedules, and violence. The heavy emphasis on physical factors is echoed in the grey literature in relevant guidance material and codes of practice focused on assessment and control of risks. There was limited evidence for interventions specific to aged care; existing evidence focused on equipment, training and education, policy and procedure. Interventions incorporating a combination of approaches, such as equipment and training, showed promise while preliminary evidence of the effectiveness of participatory approaches are positive. DISCUSSION: Interventions which address multiple types of contributing factors are needed to adequately prevent musculoskeletal injuries in aged care workers. Tweetable abstract: Review of contributing factors, interventions, and application of knowledge for work-related musculoskeletal injuries in aged care.

Drowsiness and driving performance on commuter trips.

INTRODUCTION: Driver fatigue is a major road safety problem. While much is known about the effects of fatigue and the factors that contribute to it, fatigue on commuter trips has received comparatively little attention in road safety. Most interventions have focused on longer trips, while investigations of commuting have typically examined particular groups, such as shift workers. METHOD: This study examined the effects of mild sleep deprivation on driving performance in simulated driving tasks in the morning and evening. Three groups of participants with different levels of sleep deprivation (Group 1: no deprivation; Group 2: two-hour deprivation; Group 3: four-hour deprivation) drove in a simulator for 45 min in the morning and evening, following a practice session the previous day. RESULTS: Results showed that participants reported feeling more drowsy in the afternoon, and performance impairments (increased lane deviations) were most evident in the morning for those with sleep deprivation. Measurements of eye closure did not reflect drowsiness in participants, despite performance impairments. PRACTICAL APPLICATIONS: These results suggest that mild levels of sleep deprivation (2 h), which many people regularly experience, can result in poor on-road performance, and that these effects are present in the morning, and on relatively short trips. These results warrant follow-up in naturalistic and on-road studies.

Selecting trainee pilots: Predictive validity of the WOMBAT situational awareness pilot selection test.

The WOMBAT pilot selection test is widely used to select candidates for pilot training programs. Despite use in many countries, little information is available regarding the predictive validity of the test. This study was designed to test the ability of the WOMBAT test to predict performance outcomes in a sample of ab-initio pilots. Sixty students commenced the study in 3 cohorts, and completed the WOMBAT test before their performance in the training program was evaluated through flight time to solo, flight time to licence level achievement, and instructor ratings of performance. Higher WOMBAT total scores were significantly related to reduced time to solo, achieving flight licences, as well as some early ratings of performance by flight instructors. Further research now needs to examine the exact nature of the skills and abilities that the test indexes in order to further improve pilot selection and training procedures.

Manual Handling in Aged Care: Impact of Environment-related Interventions on Mobility.

The manual handling of people (MHP) is known to be associated with high incidence of musculoskeletal disorders for aged care staff. Environment-related MHP interventions, such as appropriate seated heights to aid sit-to-stand transfers, can reduce staff injury while improving the patient's mobility. Promoting patient mobility within the manual handling interaction is an endorsed MHP risk control intervention strategy. This article provides a narrative review of the types of MHP environmental controls that can improve mobility, as well as the extent to which these environmental controls are considered in MHP risk management and assessment tools. Although a range of possible environmental interventions exist, current tools only consider these in a limited manner. Development of an assessment tool that more comprehensively covers environmental strategies in MHP risk management could help reduce staff injury and improve resident mobility through auditing existing practices and guiding the design of new and refurbished aged care facilities.

Perceptions of personal vulnerability to workplace hazards in the Australian construction industry.

INTRODUCTION: The importance of risk perception for workplace safety has been highlighted by the inclusion of risk appraisals in contemporary models of precautionary behavior at work. Optimism bias is the tendency to think that negative events are less likely to happen to oneself than to the average person, and is proposed to be related to the reduced use of precautions. METHOD: Building on studies of optimism bias for workplace hazards using samples with heterogenous risk profiles, the current study aimed to investigate whether optimism bias is present in a sample of workers exposed to similar workplace hazards. 175 Australian construction workers completed a brief survey that asked them to rate the likelihood of common construction industry hazards occurring to them and to the average worker of the same age doing the same job. Significant levels of optimism bias were found for many hazards (including being electrocuted, being trapped in a confined space, falling from heights, and causing someone else to have an injury). RESULTS: Optimism bias was not related to perceived controllability, contrary to findings in other domains, yet consistent with findings of optimism bias for workplace hazards. Optimism bias was not found to be related to a reduction in safe work behaviors, though this may be due to difficulties in measuring safe or precautionary behavior, such as social desirability. IMPACT ON INDUSTRY: That most workers think that hazards are less likely to happen to them than to the average worker presents a significant problem because it may ameliorate the efficacy of safety programs, yet constitutes a largely unexplored opportunity for improving workplace safety performance.

A reliability and usability study of TRACEr-RAV: the technique for the retrospective analysis of cognitive errors--for rail, Australian version.

The aim of this study was to compare the usability and reliability of two human error identification tools: TRACEr-Rail (developed by the Rail Safety and Standards Board in the UK) and TRACEr-RAV (an Australian specific version of the tool). Following an attempt to modify TRACEr-Rail to more appropriately suit the Australian rail context, it was predicted that TRACEr-RAV would be rated as more usable and be applied more consistently by Australian users than TRACEr-Rail. In Experiment 1, twenty-five rail employees used either TRACEr-Rail or TRACEr-RAV1 to extract and classify errors from six Australian rail incident reports. In Experiment 2, eleven university students used both TRACEr-Rail and TRACEr-RAV2 to extract and classify errors from three incident summaries. The results revealed that although modification of TRACEr-Rail to become TRACEr-RAV1 and TRACEr-RAV2 did not result in improved inter-rater reliability, modification resulted in improved ratings of usability in Experiment 2. Most participants in Experiment 2 preferred TRACEr-RAV2 to TRACEr-Rail. The poor inter-rater reliability observed was most likely the result of inadequate training, limited practice in using the tools, and insufficient human factors knowledge.

Workshop-based methodology to understand the risks in grain export inspection and certification.

Much of the human factors contribution in risk assessment and risk management has been focused on systems or product safety; the profession has a much smaller research base regarding risks to do with regulation, certification and public policy, for example. This paper discusses an explicitly human factors contribution to understanding and managing risk for the inspection and export certification of grain and plant products in Australia. Training and awareness workshops, incorporating elements of focus groups, were run for 12 groups of staff and managers from the government department concerned. As well as training in risk management the workshops were used to come to an understanding of the work of the inspectors and other staff, to identify the sources of risk to the successful completion of their work and to develop the basis for a risk assessment framework and tool. The paper is methodological in focus and describes the development and running of the workshops and explains how a human factors oriented risk register was developed on the basis of identification of potential threats and errors in the system. Whilst the contribution of ergonomics is increasingly important as regards safety risk assessment, professionals have been less active as regards business, public policy and even engineering risk. This paper describes an approach within which a new domain was studied and the risks of all kinds identified, preparatory to development of a risk assessment tool.
