Assessment of clinical consultations in an academic occupational medicine clinic.

BACKGROUND: Occupational medicine clinical consultation services are relatively under-recognized and under-utilized in Canada. AIMS: To describe clinical consultations in a university-affiliated general occupational medicine clinic. METHODS: All of the charts of patients seen in referral to our general occupational medicine clinic over a 2-year period were reviewed to extract information to provide a descriptive summary of the nature of these consultations. We evaluated patient demographic factors and work- and exposure-related information, as well as the source of referral and the nature of the presenting clinical problem. RESULTS: The 131 patients had a mean (SD) age of 50.6 (14.0) years, 55% were men and 62% were referred by their family physicians. They presented with a broad spectrum of clinical problems, with neurological problems (29%) and multisystem problems (24%) being the most prevalent. The patients worked in a variety of occupational sectors, with manufacturing and the service sector being the most frequent. Seventy-two per cent of patients came for investigation of an occupational problem and 28% came for an environmental issue. Only 36% of patients were found to have their presenting problem due to an exposure, which highlights the need for in-depth clinical assessment before making a causal attribution. CONCLUSIONS: This study provides information about the nature of clinical problems seen in an academic general occupational medicine referral clinic. The results might assist in increasing awareness and utilization of occupational medicine clinical services, which are beneficial for patient education, diagnosis and management.

Construction sector joint health and safety committees: Can their effectiveness be assessed using the JHSC assessment eTool?

BACKGROUND: Joint health and safety committees (JHSCs) are a legal requirement for most Ontario workplaces. However, few evidence-based tools exist to assess JHSC effectiveness. The JHSC Assessment eTool has been developed and tested in the healthcare and education sectors with positive results. OBJECTIVE: The objective of this study is to test the usability and feasibility of the JHSC Assessment eTool in the construction sector. METHODS: Testing was carried out in two phases using a non-experimental study design. In the first phase, construction sector health and safety experts reviewed the content of the eTool to ensure that it had relevance for the sector. In phase two, a convenience sample of JHSCs from construction sector workplaces were recruited to pilot the eTool and provide feedback. RESULTS: Feedback from six constructor sector health and safety experts and six JHSC committees indicated that the eTool had value and relevance for use in the sector. Additionally, our study identified several minor areas for refinement including the addition of construction-specific resources in the final report. CONCLUSIONS: The results of our study suggest minor modifications to the eTool for use by construction sector workplaces.

A scoping review to identify strategies that work to prevent four important occupational diseases.

BACKGROUND: Despite being largely preventable, many occupational diseases continue to be highly prevalent and extremely costly. Effective strategies are required to reduce their human, economic, and social impacts. METHODS: To better understand which approaches are most likely to lead to progress in preventing noise-related hearing loss, occupational contact dermatitis, occupational cancers, and occupational asthma, we undertook a scoping review and consulted with a number of key informants. RESULTS: We examined a total of 404 articles and found that various types of interventions are reported to contribute to occupational disease prevention but each has its limitations and each is often insufficient on its own. Our principal findings included: legislation and regulations can be an effective means of primary prevention, but their impact depends on both the nature of the regulations and the degree of enforcement; measures across the hierarchy of controls can reduce the risk of some of these diseases and reduce exposures; monitoring, surveillance, and screening are effective prevention tools and for evaluating the impact of legislative/policy change; the effect of education and training is context-dependent and influenced by the manner of delivery; and, multifaceted interventions are often more effective than ones consisting of a single activity. CONCLUSIONS: This scoping review identifies occupational disease prevention strategies worthy of further exploration by decisionmakers and stakeholders and of future systematic evaluation by researchers. It also identified important gaps, including a lack of studies of precarious workers and the need for more studies that rigorously evaluate the effectiveness of interventions.

Adult Asthma among Workers in Ontario. Results from the Occupational Disease Surveillance System.

Rationale: Given that approximately 15% of new-onset adult asthma cases originate because of exposures in the workplace, there is a need for systematic and ongoing monitoring of risk among workers. Objectives: To characterize the risk of new-onset adult asthma among workers in Ontario. Methods: We used 575,379 provincial accepted time-loss workers' compensation claimants data linked to physician billing data. Workers aged 15 to 65 years with a nonasthma compensation claim between January 1, 2002, and December 31, 2013, were eligible for inclusion. Cohort entry corresponded to the date of the claim. The case definition required two or more records for asthma within a 12-month period, within a 3-year time window after cohort entry. A 3-year washout period preceding cohort entry was used to exclude prevalent cases. Workers at risk of new-onset adult asthma were followed from cohort entry date to date of diagnosis, emigration, age 65 years, death, or end of study period. Cox regression models were used to generate birth year- and sex-adjusted hazard ratios (HRs) by occupation, industry, and exposures identified using a job exposure matrix. Sex-stratified risk estimates were also generated. Results: Increased risks were detected among well-recognized groups, including bakers (HR, 1.60; 95% confidence interval [CI], 1.22-2.09) and painters and decorators (HR, 1.67; 95% CI, 1.23-2.28). In the job exposure matrix analysis, flour and isocyanates were associated with increased risk of asthma. Concrete finishers (HR, 1.93; 95% CI, 1.12-3.32) and shipping and receiving clerks (HR, 1.21; 95% CI, 1.03-1.43) also showed elevated risk, whereas results varied across woodworker groups. Decreased risks were detected for nursing and farming groups. Conclusions: This practical data linkage approach was successful for examining associations across hundreds of jobs. Unexpected and previously unrecognized findings deserve further investigation and emphasize the importance of an ongoing system to guide research as well as prevention.

The experiences of workers who do not successfully return to work following a work-related injury.

BACKGROUND: A minority of workers with work-related injuries experience challenges returning to work. While factors that hinder return-to-work (RTW) are well-documented, the consequences of failing to successfully return to work on the lives of workers who have experienced a workplace injury remain poorly understood. OBJECTIVE: The purpose of this study is to explore the experiences of workers who do not successfully return to work following a work-related injury. METHODS: Using an interpretive approach to qualitative research and maximal variability sampling, 11 workers who have sustained work-related injuries without a successful RTW and four service providers were recruited through community organizations. Participants were interviewed using a semi-structured interview guide. A constant comparative approach was used to identify key themes across the worker and service provider experiences. RESULTS: The findings that emerged from the analysis capture the challenging RTW experiences of workers and describe wide ranging impacts on their lives when their workers' compensation claims are denied or discontinued, including ongoing financial strain, family tensions, subsequent health concerns, and negative employment experiences. The findings also highlight the negative consequences of existing cost-cutting frameworks that can restrict entitlement and benefits for many people with disabilities. CONCLUSIONS: The findings from this study highlight the experiences of workers who might need additional supports throughout the RTW process, and begin to shed light on the impact on their lives when RTW is not successful.

From awareness to action: Sudbury, mining and occupational disease in a time of change.

BACKGROUND: Miners work in highly hazardous environments, but surprisingly, there are more fatalities from occupational diseases, including cancers, than from fatalities from injuries. Over the last few decades, the mining environment has become safer with fewer injuries and less exposure to the toxins that lead to occupational disease. There have been improvements in working conditions, and a reduction in the number of workers exposed, together with an overall improvement in the health of miners. OBJECTIVES: This study attempted to gain a deeper understanding of the impetus for change to reduce occupational exposures or toxins at the industry level. It focuses on one mining community in Sudbury, Ontario, with a high cancer rate, and its reduction in occupational exposures. It explored the level of awareness of occupational exposures from the perspective of industry and worker representatives in some of the deepest mines in the world. Although awareness may be necessary, it is often not a sufficient impetus for change, and it is this gap between awareness and change that this study explored. It examined the awareness of occupational disease as an impetus to reducing toxic exposures in the mining sector, and explores other forces of change at the industrial and global levels that have led to an impact on occupational exposures in mining. METHODS: From 2014 and 2016, 60 interviews were conducted with individuals who were part of, or witness to the changes in mining in Sudbury. From these, 12 labour and 10 industry interviews and four focus groups were chosen for further analysis to gain a deeper understanding of industry and labour's views on the changes in mining and the impact on miners' health from occupational exposures. The results from this subsection of the data is the focus for this paper. RESULTS: The themes that emerged told a story about Sudbury. There is awareness of occupational exposures, but this awareness is dwarfed in comparison to the attention that is given to the tragic fatal injuries from injuries and accidents. The mines are now owned by foreign multinationals with a change from an engaged, albeit paternalistic sense of responsibility for the health of the miners, to a less responsive or sympathetic workplace culture. Modernization has led to the elimination, substitution, or reduction of some of the worst toxins, and hence present-day miners are less exposed to hazards that lead to occupational disease than they were in the past. However, modernization and the drop in the price of nickel has also led to a precipitous reduction in the number of unionized miners, a decline in union power, a decline in the monitoring of present-day exposures, and an increase in non-unionized contract workers. The impact has been that miners have lost their solidarity and power to investigate, monitor or object to present-day exposures. CONCLUSIONS: Although an increase in the awareness of occupational hazards has made a contribution to the reduction in occupational exposures, the improvement in health of miners may be considered more as a "collateral benefit" of the changes in the mining sector. Multiple forces at the industrial and global level have differentially led to an improvement in the working and living environment. However, with the loss of union power, the miners have lost their major advocate for miner health.

The structure and process of workers' compensation systems and the role of doctors: A comparison of Ontario and Québec.

BACKGROUND: This study sought to identify impacts of compensation system characteristics on doctors in Québec and Ontario. METHODS: (i) Legal analysis; (ii) Qualitative methods applied to documentation and individual and group interviews with doctors (34) and other system participants (31); and (iii) Inter-jurisdictional transdisciplinary analysis involving cross-disciplinary comparative and integrative analysis of policy contexts, qualitative data, and the relationship between the two. RESULTS: In both jurisdictions the compensation board controlled decisions on work-relatedness and doctors perceived the bureaucratic process negatively. Gatekeeping roles differed between jurisdictions both in initial adjudication and in dispute processes. Québec legislation gives greater weight to the opinion of the treating physician. These differences affected doctors' experiences. CONCLUSIONS: Policy-makers should contextualize the sources of the "evidence" they rely on from intervention research because findings may reflect a system rather than an intervention effect. Researchers should consider policy contexts to both adequately design a study and interpret their results. Am. J. Ind. Med. 59:1070-1086, 2016. © 2016 Wiley Periodicals, Inc.

The Ergonomic Program Implementation Continuum (EPIC): integration of health and safety--a process evaluation in the healthcare sector.

INTRODUCTION: This article presents a health and safety intervention model and the use of process evaluation to assess a participatory ergonomic intervention. METHOD: The effectiveness of the Ergonomic Program Implementation Continuum (EPIC) was assessed at six healthcare pilot sites in Ontario, Canada. The model provided a framework to demonstrate evaluation findings. RESULTS: Participants reported that EPIC was thorough and identified improvements related to its use. Participants believed the program contributed to advancing an organizational culture of safety (COS). Main barriers to program uptake included resistance to change and need for adequate funding and resources. The dedication of organizational leaders and consultant coaches was identified as essential to the program's success. IMPACT ON INDUSTRY: In terms of impact on industry, findings contribute to the evidence-based knowledge of health and safety interventions and support use of the framework for creating a robust infrastructure to advance organizational COS and link staff safety and wellness with patient safety in healthcare.

Factors affecting attainment of paid employment after lung transplantation.

BACKGROUND: Limited data exist regarding return to or attainment of paid employment after lung transplantation. Accordingly, the purpose of our study was to identify the issues relating to paid employment after this procedure. METHODS: We conducted a mailed survey using Dillman's protocol. We mailed questionnaires to surviving Toronto General Hospital lung transplant recipients (n = 190). We used descriptive statistics, t-tests, and chi-square tests to analyze the data. RESULTS: A total of 117 lung transplant recipients completed the questionnaires (70% response rate). The mean age of respondents was 51 +/- 13 years. Fifty-one percent of the sample were women and 72% were married. Cystic fibrosis and chronic obstructive pulmonary disease were the most frequent pre-transplant diagnoses. Fifty-six percent of participants had paid employment at some point before transplant. After transplant, 37% of respondents obtained employment. Individuals who obtained paid employment were more likely to be younger (p = 0.002), to have university degrees (p = 0.02), to report higher health ratings (p = 0.001), and to feel physically able to work (p = 0.01). They also were more likely to express a desire to enter the paid workforce (p < 0.0001); to describe receiving physician encouragement to work (p < 0.0001); to identify the possibility of obtaining paid employment as a primary motivator for the transplantation (p = 0.01); and to report that their previous jobs were available after transplantation (p = 0.01). All individuals who did not obtain paid employment cited personal or transplant-related factors. CONCLUSIONS: Medical and social factors influence attainment of paid employment after lung transplantation. Important components of the pre-transplant assessment are discussion of expectations about attaining employment and openly exploring the recipient's motivation for employment.
