A scoping review to evaluate occupational controls and their effectiveness when handling engineered nanomaterials in workplaces.

Research has shown that controlling worker exposure to engineered nanomaterials (ENMs) helps to reduce the exposure risk to employees in workplaces. This study aimed to identify the available evidence on the effectiveness of various control methods used in the workplace to reduce worker exposure to ENMs. The search was conducted in databases-Medline, OVID, Scopus, Science Direct, Web of Science, and Cochrane and the gray literature published from January 2010 to December 2022. The search keywords included ENM controls and their efficiency in workplace environments. Of the 152 studies retrieved, 22 were included in the review. The control measures in the review included (1) substitution controls; (2) engineering measures (i.e., isolation, direct source extraction, and wetting technologies); (3) personal protective equipment; and (4) administrative and work practices. The study results indicate that the above-mentioned control measures were effective in reducing ENM exposures. This information can be used to help employers choose the most effective controls for their workplaces.

Pre-employment hearing threshold levels of 59,601 Australian male coal miners compared to an otologically normal international male population (ISO7029:2019).

OBJECTIVE: This study compared the pre-employment median hearing threshold level (HTL) distribution from a population of coal miners from New South Wales (NSW), Australia, to an otologically normal, age-matched population described by the International Standards Organisation (ISO) ISO 7029:2019, to determine any differences. DESIGN: This was an observational, retrospective, repeated cross-sectional study. STUDY SAMPLE: De-identified audiometric records of 59,601 male employees entering NSW coal mining in three representative five-year periods between 1991 and 2015 were utilised. RESULTS: The median HTL deviation of the mining population was statistically significantly different (p < 0.05) from the ISO population, for almost all analyses. Overall, the mining population cohorts have higher (worse) median HTLs compared to the ISO population. The greatest difference occurs at 4 kHz in older age groups, likely indicating noise-induced hearing loss. CONCLUSION: These findings indicate that some NSW coal mine workers commence their careers with evidence of pre-existing hearing loss (HL), in an industry with excessive noise exposures. These results provide Australian mining and other noisy industries with evidence to support a review of hearing conservation strategies to improve mitigation of hearing loss across the working lifespan.

The coal mining industry in Australia typically employs 20,000­30,000 workers annually. These workers are potentially exposed to noise levels between 80 dB(A) and 120 dB(A) whilst at work, and thus at high risk of developing noise induced hearing loss (NIHL). NIHL is the most compensated, occupational disease for coal mining in Australia, costing the Australian State of New South Wales (NSW) up to $4 million each year. And yet: NIHL is entirely preventable.This is the second of two studies of Australian coal mining, analysing a database containing de-identified mandatory audiometric testing results. Evidence of hearing loss within this population was determined in the first study, and the aim of this follow-up study was to determine if there were differences in the median hearing threshold levels in the mining population compared to an otologically normal, international population (ISO7029). The results indicate that the mining population HTLs for males are significantly different (worse) compared to an age and gender matched otologically normal population, specifically at 4 kHz for older workers. Evidence of age-related hearing loss was also found.From a workplace perspective, employers need to consider appropriate workplace interventions to promote hearing loss prevention strategies across the workforce. This information can be used to inform future noise and hearing policies and procedures within this, as well as other noisy industries, to prevent and reduce further exposure of workers to excessive noise.

Variations in Concurrent Validity of Two Independent Inertial Measurement Units Compared to Gold Standard for Upper Body Posture during Computerised Device Use.

Inertial measurement units (IMUs) may provide an objective method for measuring posture during computer use, but research is needed to validate IMUs' accuracy. We examine the concurrent validity of two different IMU systems in measuring three-dimensional (3D) upper body posture relative to a motion capture system (Mocap) as a potential device to assess postures outside a laboratory environment. We used 3D Mocap and two IMU systems (Wi-Fi and Bluetooth) to capture the upper body posture of twenty-six individuals during three physical computer working conditions (monitor correct, monitor raised, and laptop). Coefficient of determination (R2) and root-mean-square error (RMSE) compared IMUs to Mocap. Head/neck segment [HN], upper trunk segment [UTS], and joint angle [HN-UTS] were the primary variables. Wi-Fi IMUs demonstrated high validity for HN and UTS (sagittal plane) and HN-UTS (frontal plane) for all conditions, and for HN rotation movements (both for the monitor correct and monitor raised conditions), others moderate to poor. Bluetooth IMUs for HN, and UTS (sagittal plane) for the monitor correct, laptop, and monitor raised conditions were moderate. Frontal plane movements except UTS (monitor correct and laptop) and all rotation had poor validity. Both IMU systems were affected by gyroscopic drift with sporadic data loss in Bluetooth IMUs. Wi-Fi IMUs had more acceptable accuracy when measuring upper body posture during computer use compared to Mocap, except for trunk rotations. Variation in IMU systems' performance suggests validation in the task-specific movement(s) is essential.

Mental health and mining: the Ghanaian gold mining story.

PURPOSE: There is limited empirical evidence regarding mental health in workplace settings in Africa. Gold mining is a major industry in Ghana, and this study investigated mental health-related symptoms and the factors contributing to such symptoms among employees in the Ghanaian. METHODS: A cross-sectional survey design study was used to collect data from employees working in the mining industry across five gold mines in Ghana. All mining employees were invited to participate in the survey. Sociodemographic and work characteristic data (including job content) was collected alongside measures of recent mental health-related symptoms (Kessler-10). Questionnaires were administered in English. Data were analysed using descriptive statistics and logistic regression models. RESULTS: Of 1165 participants (response rate: 78%), 87% were male and 13% were female. The majority of the participants were in the 25-34 age category. Psychological distress was categorized as low (62.6%), moderate (24.3%), high (10.0%) and very high (3.2%). Shift type (working 12 h or more), physical working conditions and financial factors were significantly associated with psychological distress. Job resources and job demands was not significantly associated with levels of psychological distress. CONCLUSION: This is the first study to explore mental health in the Ghanaian gold mining industry. The findings identify workplace factors associated with psychological distress in the mining industry in Ghana and support the importance of promoting mental health as part of workplace health and safety strategy to improve mental health across the mining population.

Hearing threshold levels of Australian coal mine workers: a retrospective cross-sectional study of 64196 audiograms.

OBJECTIVE: This study examined the hearing threshold levels (HTL) of workers commencing employment in Australian coal mines in the State of New South Wales (NSW). The aim was to establish if some degree of hearing loss was identifiable in the mandatory pre-employment audiograms of workers. DESIGN: This was an observational, retrospective, repeated cross-sectional study. STUDY SAMPLE: De-identified audiometric records of 64196 employees entering NSW coal mining in three representative five-year periods between 1991-2015 were utilised. RESULTS: Although HTLs were lower (better) in more recent years, the results showed clinically significant hearing loss (≥25dBHL) for older workers, 45-60 years. Pure tone average (PTA) hearing losses were greater at the higher frequencies associated with excessive noise exposure (3-6 kHz), than at the speech frequencies (0.5-4 kHz). Hearing loss in the left ears were higher compared to the right ears, with higher prevalence of audiometric notches in males. CONCLUSION: Almost a fifth (14.8-20.1%) of male workers commencing work in NSW coal mines presented with an audiometric notch at 4 kHz. Further research is required to determine if these notches represent true NIHL, and how the residual hearing of workers may be conserved.

Evidence for the Effectiveness of Feedback from Wearable Inertial Sensors during Work-Related Activities: A Scoping Review.

Background: Wearable inertial sensor technology (WIST) systems provide feedback, aiming to modify aberrant postures and movements. The literature on the effects of feedback from WIST during work or work-related activities has not been previously summarised. This review examines the effectiveness of feedback on upper body kinematics during work or work-related activities, along with the wearability and a quantification of the kinematics of the related device. Methods: The Cinahl, Cochrane, Embase, Medline, Scopus, Sportdiscus and Google Scholar databases were searched, including reports from January 2005 to July 2021. The included studies were summarised descriptively and the evidence was assessed. Results: Fourteen included studies demonstrated a 'limited' level of evidence supporting posture and/or movement behaviour improvements using WIST feedback, with no improvements in pain. One study assessed wearability and another two investigated comfort. Studies used tri-axial accelerometers or IMU integration (n = 5 studies). Visual and/or vibrotactile feedback was mostly used. Most studies had a risk of bias, lacked detail for methodological reproducibility and displayed inconsistent reporting of sensor technology, with validation provided only in one study. Thus, we have proposed a minimum 'Technology and Design Checklist' for reporting. Conclusions: Our findings suggest that WIST may improve posture, though not pain; however, the quality of the studies limits the strength of this conclusion. Wearability evaluations are needed for the translation of WIST outcomes. Minimum reporting standards for WIST should be followed to ensure methodological reproducibility.

Changes in emotions and perceived stress following time spent in an artistically designed multisensory environment.

Self-management strategies that enhance positive emotions are considered most effective to cope with stress and maintain good mental health and well-being. An artistically designed multisensory environment, The Sensory-Art Space (SAS), was installed in a university in NSW Australia as a new self-management intervention. The design of the SAS was informed by evidence regarding the benefits of viewing art, experiencing nature and accessing sensory rooms.A pilot pre-post intervention study measured changes in affect and perceived stress in 224 participants who spent time in the SAS. Descriptive statistics were completed on the individual affective states, and paired sample t-tests were used to determine changes in Positive and Negative Affect (PANAS-X) and perceived stress (Visual Analogue Scale).The Wilcoxon signed-rank test showed that negative affect reduced, z=-10.23 (p<0.001), and positiveaffect increased, z=-2.57 (p=0.01), following spending time in the SAS. In addition, stress levels reduced after time spent in the SAS, z=-11.29 (p<0.0001).Self-management benefits were found following time in the SAS and future implications for public health and well-being are discussed.

It's like another world: the perceived beneficial effects of an artistically designed multisensory environment.

Self-management strategies have been identified as having a key role in supporting mental health and preventing mental illness. Evidence suggests that spending time in nature, experiencing or viewing artwork and accessing sensory rooms all support self-management and positive mental health among varied clinical populations. This evidence informed the design of the sensory-art space (SAS), an artistically designed multisensory environment, which drew on themes and images of nature.The aim of this study was to explore the experiences and perceived benefits of the SAS among members of a university community.A maximum variation approach to sampling was used, and 18 participants were included in this qualitative study. Data were gathered via semi-structured interviews, which were audio-recorded and transcribed verbatim for thematic analysis.The findings presented six themes. The two core themes were: it's like another world, and easy to focus and describe how the SAS produced the beneficial effects described in the four remaining themes of: emotionally nutritious, meditative effects, relaxation and therapeuticParticipants identified beneficial effects of the SAS that were consistent with the evidence for other self-management strategies. The identified benefits also aligned with existing theories suggesting that the SAS functioned as a restorative environment. This study is the first to explore the experience of art in a multisensory and multidimensional capacity, which further contributes to the growing field of receptive engagement with the arts for health outcomes.

Occupational Therapy Domestic Needs Assessment: Lawyer Perspectives.

Occupational therapists are experts in understanding the impact an injury has on a claimant's capacity to perform their pre-injury level of domestic activities. Lawyers use this information when litigating claims for domestic assistance support. This is the first study exploring lawyers' experiences with occupational therapy domestic assistance reports using an online survey. The online survey was completed by 20 lawyers who practise in New South Wales, Australia. Results indicated occupational therapy reports were used to determine the amount of gratuitous domestic care the claimant received, the impact injury has on daily function and tasks requiring assistance. Lawyers used therapists with medico-legal experience although the timeframe for receiving the report was also influential. A high-quality report uses supportive evidence linking function and recommendations for care. Therapists require a clear understanding of the legislation and transparent reasoning while lawyers need to provide sufficient information to assist therapists' conclusions.

Content validity of the WorkHab functional capacity evaluation.

INTRODUCTION: Validity is a dynamic process and as part of a continual process of evaluation of tools, this study aimed to evaluate content validity of the WorkHab functional capacity evaluation, a tool used in occupational rehabilitation. METHODS: A cross sectional survey of health professionals who conduct FCEs investigated their ratings of item relevance and item difficulty across different categories of work and injuries. The survey also explored the relationship of the WorkHab FCE items with the physical demand items of the Dictionary of Occupational Titles (DOT). RESULTS: The majority of items of the WorkHab FCE were rated as relevant for manual work and vocational retraining with over 90% agreement between the 106 respondents. Therapists identified the WorkHab items of climbing, crawling and balance as less relevant for sedentary work. Lifting items were perceived as the most difficult for those with a lower back injury, or an upper limb injury. Sixteen of the 18 WorkHab FCE items had 100% agreement with the equivalent items on the DOT. The WorkHab FCE items that had poor agreement with the DOT were mainly sensory items such as see, feel, talk and hear. CONCLUSIONS: The findings of this study support the content validity for the WorkHab FCE specifically in relation to manual work and for vocational retraining purposes.

Occupational therapy intervention addressing weight gain and obesity in people with severe mental illness: A scoping review.

BACKGROUND: Individuals diagnosed with severe mental illness have higher rates of obesity than the general population due to a range of factors, including: medication side effects, poor nutrition and reduced physical activity. Obesity is associated with increased mortality and reduced quality of life. Evidence suggests that lifestyle interventions can be effective in addressing this issue. While such interventions would appear to fit within the scope of practice of occupational therapy, there is no publication synthesising the existing literature regarding occupational therapy interventions addressing lifestyle factors associated with obesity. AIM: To determine what is known from the existing literature about occupational therapy interventions addressing weight gain and obesity in adults diagnosed with severe mental illness. METHODS: A scoping review was conducted. Searches were performed in online databases, occupational therapy journals and grey literature databases. Thematic analysis occurred across all articles included in the review. RESULTS: A total of 14 articles were included in the review. Analysis revealed a central theme of supporting occupational performance and participation in health promoting occupations. This central theme consisted of four categories; facilitating client-centred practice, addressing personal performance issues, addressing environmental barriers and providing the 'just right' challenge. CONCLUSION/SIGNIFICANCE: These findings suggest occupational therapists are providing occupation focused interventions that are aligned with current clinical guidelines. However, more research is required to strengthen evidence-based occupational therapy practice in this important area.

Occupational therapy medicolegal assessment of domestic assistance requirements: Focus group perspectives.

BACKGROUND/AIM: Estimating domestic assistance requirements within the medicolegal field is a role for occupational therapists. It is a complex multidimensional process of clinical reasoning with no published research outlining how an occupational therapist translates assessment data into the number of hours of domestic assistance required. This study describes the current occupational therapy practice of estimating domestic assistance hours within the medicolegal context. METHOD: Three focus groups, totalling 14 occupational therapists providing medicolegal reports in New South Wales, were conducted. Sydney University provided ethics approval. Focus group data were thematically analysed. RESULTS: Four themes were identified: Tasks included as housework. Assessment process - interview of pre-injury and recovery status; functional performance on specific tasks and a tour of the home. Influential factors - include legal system restrictions, medical management, cultural and society values, family expectations, location and impact of diagnosis. Strategies to determine care - triangulation of observed data with medical reports and clinical experience. Knowledge of community and own performance times within the framework of occupational therapy philosophy DISCUSSION: No single method of translating assessment data to hours of care was identified. Therapists use of their own housework performance raises ethical issues. Use of claimant only statements raises issues of inaccurate data on which to base decisions. Therapists should refer to occupational therapy process of clinical reasoning to explain their recommendations even though the reasoning does not give a definite number of care hours. CONCLUSION: Therapists need to understand the factors influencing their clinical reasoning when integrating all available information into an estimating of domestic assistance hours. Further study analysing the content of medicolegal report may provide information as to how therapists document their clinical reasoning for court.

The "Double Whammy": Women's Experiences of Weight Gain After Diagnosis and Treatment for Schizophrenia Spectrum Disorders.

High levels of lifestyle risk factors compound medication side effects, resulting in high rates of obesity among people with schizophrenia spectrum disorders (SSDs). Obesity and related comorbidities increase the levels of disability and disadvantage in this population. Little research has explored the lived experiences in relation to this issue, and less has considered the experiences of women. Our aim in this study was to understand the experiences of women who gained weight after their diagnosis and treatment for SSDs. We carried out up to three in-depth qualitative interviews with 11 women over 2 years. Data were analyzed using constructivist grounded theory procedures. The women described a "double whammy"-like experience whereby weight gain and obesity came with their diagnosis and treatment of an SSD and brought with it additional challenges. The double whammy parallels the co-occurrence of mental illness and substance misuse. Implications of these parallels for service provision are discussed.

Practices and Processes Used in the Return to Work of Injured New South Wales nurses: Are These Consistent With RTW Best Practice Principles?

Purpose Workplace injury and illness rates are high within the nursing profession, and in conjunction with current nursing shortages, low retention rates, and the high cost of workplace injury, the need for effective return to work (RTW) for injured nurses is highlighted. This study aimed to identify current practices and processes used in the RTW of injured nurses, and determine if these are consistent with the seven principles for successful RTW as described by the Canadian Institute for Work & Health. Method As part of a larger cross-sectional study, survey data were collected from New South Wales nurses who had sustained a major workplace injury or illness. Survey questions were coded and matched to the seven principles for successful RTW. Results Of the 484 surveys eligible for analysis, most were from Registered Nurses (52%) in the Public Hospital Sector (48%). Responses indicated four main areas of concern: a commitment to health and safety by the workplace; early and considerate employer contact; provision of modified work; and individual knowledge of and involvement in the RTW process. Positive participant responses to co-worker and supervisor involvement were identified as areas consistent with best practice principles. Conclusions These findings suggest the practices and processes involved in the RTW of injured nurses are inconsistent with best practice principles for RTW, highlighting the need for interventions such as targeted employer education and training for improved industry RTW outcomes.

Alcohol consumption in the Australian coal mining industry.

OBJECTIVES: To investigate patterns of alcohol use within the coal mining industry, and associations with the personal, social, workplace and employment characteristics. DESIGN: 8 mine sites across 3 eastern Australian states were surveyed, selected to encompass key geographic characteristics (accessibility and remoteness) and mine type (open cut and underground). Problematic alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT) to determine: (1) overall risky or hazardous drinking behaviour; and (2) frequency of single-occasion drinking (6 or more drinks on 1 occasion). RESULTS: A total of 1457 employees completed the survey, of which 45.7% of male and 17.0% of female participants reported levels of alcohol use within the range considered as risky or hazardous, considerably higher than the national average. Hierarchical linear regression revealed a significant contribution of many individual level factors associated with AUDIT scores: younger age, male, current smoking status; illicit substance use; previous alcohol and other drug use (AOD) problems; and higher psychological distress. Workplace factors associated with alcohol use included working in mining primarily for the high remuneration, and the type of mining, with underground miners reporting higher alcohol use than open-cut miners. CONCLUSIONS: Our findings provide support for the need to address alcohol use in the coal mining industry over and above routine on-site testing for alcohol use.

Shifting gears: An inpatient medical record audit and post-discharge survey of return-to-driving following stroke/transient ischaemic attack.

BACKGROUND/AIM: In Australia, all stroke survivors should not drive for four weeks and transient ischaemic attack (TIA) survivors should not drive for two weeks. This study investigates the provision of return-to-driving education in the acute hospital setting and the use of this education by a cohort of Australian patients who have experienced a mild stroke or TIA and who are discharged directly home from their acute hospital admission. METHODS: A medical record audit was conducted of stroke patients discharged home from a regional hospital in Australia. All audited patients were sent a post-discharge anonymous survey of their post-stroke driving behaviours. RESULTS: A total of 78 medical records were audited (32 women, 46 men; 15 TIA, 63 strokes). Mean age was 67.4 years (SD = 13.7, range 20-89 years). Only 27 (34.6%) patients had documented evidence that return-to-driving was discussed with them by a health professional, with only 10 (12.8%) having a restriction period documented. A total of 31 surveys were analysed (10 females, 21 males) and 20 participants had returned to driving. From 31 survivors of mild stroke/TIA, 21 recalled receiving advice on return-to-driving and seven resumed driving during the non-driving period of one month. CONCLUSIONS: Inconsistencies exist in the documentation of return-to-driving management after acute stroke or TIA and it is unknown whether patients who lack documentation in their medical records were provided with education or not.

An exploratory study into the application of psychological theories and therapies in Australian mental health occupational therapy practice: Challenges to occupation-based practice.

BACKGROUND: While legitimate practice tools have been the subject of debate within the profession, little attention has been paid to psychological frames of reference (PFsOR). Hence, this article explores the ways psychological theories and therapies shape occupation-based practice in mental health settings. METHODOLOGY: Narrative inquiry methods and thematic analysis were used to explore the career stories of nine occupational therapists who had worked in mental health practice for more than five years. FINDINGS: Respondents found it difficult to hold onto their occupational focus in the psychology-dominated world of mental health practice. The main themes to emerge were (i) tension between occupation and psychology; (ii) overwhelming pressures to adopt PFsOR; (iii) resistance to PFsOR; and (iv) using PFsOR to enhance professional repertoires. Findings pointed to the need to ensure PFsOR include occupational considerations for occupation-based practice in mental health. CONCLUSION: A occupation-based perspective means balancing PFsOR with occupation-based considerations, so service-user issues are holistically addressed. There is a need to critically review occupational therapists' use of PFsOR lest their most visible practical actions appear psychologically based rather than occupation based.

In the Driver's Seat: Development and Implementation of an e-Learning Module on Return-to-Driving After Stroke.

Gaps exist in the knowledge of return-to-driving guidelines, and education is needed for Australian health professionals working in the field of stroke. In this paper, authors evaluate the implementation of an e-learning module. A pre- and post-module knowledge test and survey were used to assess the e-module's success in achieving its learning objectives. Initially, 204 learners completed the module, with 68% of learners scoring 100% in the post-module knowledge test. Only 12 learners completed the survey. The authors recommend that health professionals other than occupational therapists access this e-module, and a review on e-module structure is required to improve results of knowledge tests.

Help-seeking for mental health problems by employees in the Australian Mining Industry.

BACKGROUND: The current study examined help-seeking behavior for mental health problems of employees in the mining industry. METHODS: The research involved a paper-based survey completed by a cross-section of employees from eight coalmine sites. The research aimed to investigate the frequency of contact with professional and non-professional sources of support, and to determine the socio-demographic and workplace factors associated. RESULTS: A total of 1,457 employees participated, of which, 46.6 % of participants reported contact with support to discuss their own mental health within the preceding 12 months. Hierarchical logistic regression revealed a significant contribution of workplace variables, with job security and satisfaction with work significantly associated with help-seeking behavior. CONCLUSIONS: The results provide an insight into the help-seeking behaviour of mining employees, providing useful information to guide mental health workplace program development for the mining industry, and male-dominated industry more broadly.

The role of the Australian workplace return to work coordinator: essential qualities and attributes.

INTRODUCTION: In the Australian context, a return to work (RTW) Coordinator assists an injured worker with workplace-based support and regulatory guidance for the duration of their injury. Coordinating the RTW process has been considered an effective approach for managing workplace injuries, however few studies have described the skills, traits or characteristics required to fulfil the role of workplace RTW Coordinator. This study aims to provide insight as to the skills and attributes needed for the role of the workplace RTW Coordinator from their experience and perception. METHOD: Focus groups were conducted with workplace RTW Coordinators from six major Australian cities. Twenty five participants were recruited through a national RTW Coordinator website, and professional RTW interest groups using a snowballing technique. Participating workplace RTW Coordinators were required to have a minimum 2 years' experience and to have been involved with the development and implementation of workplace policies and procedures. Thematic analysis was performed to identify meaningful patterns and themes. RESULTS: The data analysed provided clear insight as to the specific role requirements necessary for working as an Australian workplace RTW Coordinator. Three key themes clearly emerged; communication skills, RTW Coordinator characteristics, and managing the RTW process. CONCLUSION: The findings indicate that RTW Coordinators require a wide range of traits, skills, and attributes to successfully perform this role. Effective management by the RTW Coordinator of the complex RTW process is essential to facilitate a smooth transition for the injured worker, alongside maintaining a professional relationship with the employer and external stakeholders. The results of this study can be utilised to further improve the selection of future RTW Coordinators.
